But one thing isn’t up for debate: the evidence for climate change is unequivocal. We still control the future, however, as the magnitude of shifting weather patterns and the frequency of extreme climate events depends on how much more greenhouse gas we emit. We aren’t facing the end of the world as envisaged by many environmentalists in the late 1980s and early 1990s, but if we do nothing to mitigate climate change then billions of people will suffer. Causes of climate change Greenhouse gases absorb and re-emit some of the heat radiation given off by the Earth’s surface and warm the lower atmosphere. The most important greenhouse gas is water vapour, followed by carbon dioxide and methane, and without their warming presence in the atmosphere the Earth’s average surface temperature would be approximately -20°C. While many of these gases occur naturally in the atmosphere, humans are responsible for increasing their concentration through burning fossil fuels, deforestation and other land use changes. Records of air bubbles in ancient Antarctic ice show us that carbon dioxide and other greenhouse gases are now at their highest concentrations for more than 800,000 years. Evidence for climate change The Intergovernmental Panel on Climate Change (IPCC) presents six main lines of evidence for climate change. 1. We have tracked the unprecedented recent increase in the amount of atmospheric carbon dioxide and other greenhouse gases since the beginning of the industrial revolution. 2. We know from laboratory and atmospheric measurements that such greenhouse gases do indeed absorb heat when they are present in the atmosphere. 3. We have tracked significant increase in global temperatures of at least 0.85°C and a sea level rise of 20cm over the past century. 4. We have analysed the effects of natural events such as sunspots and volcanic eruptions on the climate, and though these are essential to understand the pattern of temperature changes over the past 150 years, they cannot explain the overall warming trend. 5. We have observed significant changes in the Earth’s climate system including reduced snowfall in the Northern Hemisphere, retreat of sea ice in the Arctic, retreating glaciers on all continents, and shrinking of the area covered by permafrost and the increasing depth of its active layer. All of which are consistent with a warming global climate. 6. We continually track global weather and have seen significant shifts in weather patterns and an increase in extreme events all around the world. Patterns of precipitation (rainfall and snowfall) have changed, with parts of North and South America, Europe and northern and central Asia becoming wetter, while the Sahel region of central Africa, southern Africa, the Mediterranean and southern Asia have become drier. Intense rainfall has become more frequent, along with major flooding. We’re also seeing more heat waves. According to the US National Oceanic and Atmospheric Administration (NOAA) between 1880 and the beginning of 2014, the 19 warmest years on record have all occurred within the past 20 years; and 2015 is set to be the warmest year ever recorded. What the future holds The continued burning of fossil fuels will inevitably lead to further climate warming The complexity of the climate system is such that the extent of this warming is difficult to predict, particularly as the largest unknown is how much greenhouse gas we keep emitting. The IPCC has developed a range of emissions scenarios or Representative Concentration Pathways (RCPs) to examine the possible range of future climate change. Using scenarios ranging from business-as-usual to strong longer-term managed decline in emissions, the climate model projections suggest the global mean surface temperature could rise by between 2.8°C and 5.4°C by the end of the 21st century. Even if all the current country pledges submitted to the Paris conference are achieved we would still only just be at the bottom end of this range. The sea level is projected to rise by between 52cm and 98cm by 2100, threatening coastal cities, low-lying deltas and small island nations. Snow cover and sea ice are projected to continue to reduce, and some models suggest that the Arctic could be ice-free in late summer by the latter part of the 21st century. Heat waves, droughts, extreme rain and flash flood risks are projected to increase, threatening ecosystems and human settlements, health and security. One major worry is that increased heat and humidity could make physical work outside impossible. Changes in precipitation are also expected to vary from place to place. In the high-latitude regions (central and northern regions of Europe, Asia and North America) the yearround average precipitation is projected to increase, while in most sub-tropical land regions it is projected to decrease by as much as 20%, increasing the risk of drought. In many other parts of the world, species and ecosystems may experience climatic conditions at the limits of their optimal or tolerable ranges or beyond. Human land use conversion for food, fuel, fibre and fodder, combined with targeted hunting and harvesting, has resulted in species extinctions some 100 to 1000 times higher than background rates. Climate change will only speed things up. We don’t have much time left This is the challenge our world leaders face. To keep global temperature rise below the agreed 2°C, global carbon emission must peak in the next decade and from 2070 onward must be negative: we must start sucking out carbon dioxide from the atmosphere. Defer to consensus – skeptics are wrong – contradictory research, cherry-picking, curve-fitting, and ignoring data. Shermer 15 (Dr. Michael Shermer is Founding Publisher of Skeptic magazine, Executive Director of the Skeptics Society, and columnist for Scientific American; "Why Climate Skeptics Are Wrong"; 12-1-2015; Scientific American; http://www.scientificamerican.com/article/why-climate-skeptics-are-wrong/; DT) At some point in the history of all scientific theories, only a minority of scientists—or even just one—supported them, before evidence accumulated to the point of general acceptance. The Copernican model, germ theory, the vaccination principle, evolutionary theory, plate tectonics and the big bang theory were all once heretical ideas that became consensus science. How did this happen? An answer may be found in what 19th-century philosopher of science William Whewell called a “consilience of inductions.” For a theory to be accepted, Whewell argued, it must be based on more than one induction—or a single generalization drawn from specific facts. It must have multiple inductions that converge on one another, independently but in conjunction. “Accordingly the cases in which inductions from classes of facts altogether different have thus jumped together,” he wrote in his 1840 book The Philosophy of the Inductive Sciences, “belong only to the best established theories which the history of science contains.” Call it a “convergence of evidence.” Consensus science is a phrase often heard today in conjunction with anthropogenic global warming (AGW). Is there a consensus on AGW? There is. The tens of thousands of scientists who belong to the American Association for the Advancement of Science, the American Chemical Society, the American Geophysical Union, the American Medical Association, the American Meteorological Society, the American Physical Society, the Geological Society of America, the U.S. National Academy of Sciences and, most notably, the Intergovernmental Panel on Climate Change all concur that AGW is in fact real. Why? It is not because of the sheer number of scientists. After all, science is not conducted by poll. As Albert Einstein said in response to a 1931 book skeptical of relativity theory entitled 100 Authors against Einstein, “Why 100? If I were wrong, one would have been enough.” The answer is that there is a convergence of evidence from multiple lines of inquiry—pollen, tree rings, ice cores, corals, glacial and polar ice-cap melt, sea-level rise, ecological shifts, carbon dioxide increases, the unprecedented rate of temperature increase—that all converge to a singular conclusion. AGW doubters point to the occasional anomaly in a particular data set, as if one incongruity gainsays all the other lines of evidence. But that is not how consilience science works. For AGW skeptics to overturn the consensus, they would need to find flaws with all the lines of supportive evidence and show a consistent convergence of evidence toward a different theory that explains the data. (Creationists have the same problem overturning evolutionary theory.) This they have not done. A 2013 study published in Environmental Research Letters by Australian researchers John Cook, Dana Nuccitelli and their colleagues examined 11,944 climate paper abstracts published from 1991 to 2011. Of those papers that stated a position on AGW, about 97 percent concluded that climate change is real and caused by humans. What about the remaining 3 percent or so of studies? What if they're right? In a 2015 paper published in Theoretical and Applied Climatology, Rasmus Benestad of the Norwegian Meteorological Institute, Nuccitelli and their colleagues examined the 3 percent and found “a number of methodological flaws and a pattern of common mistakes.” That is, instead of the 3 percent of papers converging to a better explanation than that provided by the 97 percent, they failed to converge to anything. “There is no cohesive, consistent alternative theory to human-caused global warming,” Nuccitelli concluded in an August 25, 2015, commentary in the Guardian. “Some blame global warming on the sun, others on orbital cycles of other planets, others on ocean cycles, and so on. There is a 97% expert consensus on a cohesive theory that's overwhelmingly supported by the scientific evidence, but the 2–3% of papers that reject that consensus are all over the map, even contradicting each other. The one thing they seem to have in common is methodological flaws like cherry picking, curve fitting, ignoring inconvenient data, and disregarding known physics.” For example, one skeptical paper attributed climate change to lunar or solar cycles, but to make these models work for the 4,000-year period that the authors considered, they had to throw out 6,000 years' worth of earlier data. Such practices are deceptive and fail to further climate science when exposed by skeptical scrutiny, an integral element to the scientific process. We don’t have time to wait – warming is anthropogenic but there’s no impact unless we exceed a tipping point of 2 degrees. Harvey 13 (Fiona Harvey is an award-winning environment journalist for the Guardian; “IPCC: 30 years to climate calamity if we carry on blowing the carbon budget”; https://www.theguardian.com/environment/2013/sep/27/ipccworld-dangerous-climate-change; The Guardian; https://www.theguardian.com/environment/2013/sep/27/ipcc-worlddangerous-climate-change; DT) The world's leading climate scientists have set out in detail for the first time how much more carbon dioxide humans can pour into the atmosphere without triggering dangerous levels of climate change – and concluded that more than half of that global allowance has been used up. If people continue to emit greenhouse gases at current rates, the accumulation of carbon in the atmosphere could mean that within as little as two to three decades the world will face nearly inevitable warming of more than 2C, resulting in rising sea levels, heatwaves, droughts and more extreme weather. This calculation of the world's "carbon budget" was one of the most striking findings of the Intergovernmental Panel on Climate Change (IPCC), the expert panel of global scientists who on Friday produced the most comprehensive assessment yet of our knowledge of climate change at the end of their four-day meeting in Stockholm. The 2,000-plus page report, written by 209 lead authors, also found it was "unequivocal" that global warming was happening as a result of human actions, and that without "substantial and sustained" reductions in greenhouse gas emissions we will breach the symbolic threshold of 2C of warming, which governments around the world have pledged not to do. Ban Ki-moon, the UN secretary-general, urged world leaders to pay heed to the "world's authority on climate change" and forge a new global deal on cutting emissions. "The heat is on. Now we must act," he said. John Kerry, the US secretary of state, said in a statement: "This is yet another wakeup call: those who deny the science or choose excuses over action are playing with fire." "Once again, the science grows clearer, the case grows more compelling, and the costs of inaction grow beyond anything that anyone with conscience or commonsense should be willing to even contemplate," he added. The IPCC also rebuffed the argument made by climate sceptics that a "pause" for the last 10-15 years in the upward climb of global temperatures was evidence of flaws in their computer models. In the summary for policymakers, published on Friday morning after days of deliberations in the Swedish capital, the scientists said: "Each of the last three decades has been successively warmer at the Earth's surface than any preceding decade since 1850. In the northern hemisphere, 19832012 was likely the warmest 30-year period of the last 1,400 years." Thomas Stocker, co-chair of the report working group, said measuring recent years in comparison to 1998, an exceptionally hot year, was misleading and that temperature trends could only be observed over longer periods, of about 30 years. International policies fall short of that target – we still have time to meet it but immediacy is key – expert analysis agrees. Radford 16 (Tim Radford, a founding editor of Climate News Network, worked for The Guardian for 32 years, for most of that time as science editor. He has been covering climate change since 1988; "Pledges Made at Paris Climate Talks Will Not Contain Global Warming"; 7-12-2016; Truthdig; http://www.truthdig.com/report/item/pledges_made_at_the_paris_climate_talks_will_not_contain_20160702; DT) LONDON—National promises made late last year to contain carbon dioxide emissions will not be nearly enough to meet the global warming target agreed last December by 195 nations, according to a new assessment. The signatories to the historic agreement at the UN conference on climate change in Paris pledged to limit global warming to below 2°C and to aim for no more than 1.5°C rise above pre-industrial levels. The planet has already warmed by 1°C in the last century. But, climate scientists say, the intended nationally determined contributions (INDCs) submitted before the meeting imply global warming of between 2.6°C and 3.1°C. So more needs to be done, they report in Nature journal. “The Paris Agreement was a historical achievement for the world’s response to climate change, aiming at limiting warming to below 1.5°C and 2°C,” says Joeri Rogelj, the International Institute for Applied Systems Analysis (IIASA) research scholar who led the study. Finite amount “It puts in place a flexible framework for a long-term transformation towards a low-carbon society. But our analysis shows that these measures need to be strengthened in order to have a good chance of keeping warming to well below 2°C, let alone 1.5°C.” The researchers argue in their study that to limit warming to any level implies that the total amount of CO2 that can ever be emitted into the atmosphere is finite. “About two-thirds of the available budget for keeping warming to below 2°C have already been emitted,” they write. “Global emissions urgently need to start to decline.” That it can be done, and that the Paris target is realistic and achievable, is confirmed by a second group of researchers in Nature Climate Change journal. “In order to ensure a chance of meeting these targets, we need further significant action from countries before 2030.” They reason that the difference between 1.5°C and 2°C is substantial, in terms of sea level rise, the loss of the glaciers and damage to the rainforests. However, the process of containing global average temperature rise demands a “controlled implosion” of the fossil fuel industry, and a technological explosion of renewable energy systems. “The Paris agreement is a historic achievement and a genuine triumph of reason,” says Hans Joachim Schellnhuber, director of the Potsdam Institute for Climate Impact Research, who led the study. “Now the pressure is on to implement that consensus in time, in order to avoid the looming humanitarian tragedy for good.” And the latest look at the challenges, led by the IIASA team, is another instance of that pressure. The researchers calculate—on the basis of all the INDCs submitted by the time of the Paris meeting, from up to 187 of the parties to the conference, and responsible for up to 96% of all greenhouse gas emissions—that the entire global budget for limiting global warming to below 2°C might have already been emitted by 2030. To put it briefly, the promises made so far are not enough. Since the Paris Agreement requires the signatories to submit fresh and ever more ambitious INDC pledges every five years, political opportunity exists, along with societal challenge. Range of uncertainties The latest Nature study considers a number of scenarios and a range of uncertainties, and then goes on to frame the probabilities of success. And it concludes that “substantial enhancement or over-delivery” of the promises made so far is necessary to maintain a reasonable chance of keeping warming to well below the 2°C target. “To go the rest of the way, we would need to assume much more stringent action after 2030, which leads to emissions reductions of 3%-4% per year globally,” says the report’s co-author, Niklas Höhne, founding partner of the Germany-based NewClimate Institute for Climate Policy and Global Sustainability. “But, in practice, switching to such stringent reductions right after 2030 would be challenging, and require time. That means that in order to ensure a chance of meeting these targets, we need further significant action from countries before 2030.” Several scenarios – One – warming over 2 degrees causes extinction – agriculture loss, collapse of civilization, and reverse carbon cycle.

Beyond two degrees, however, preventing mass starvation will be as easy as halting the cycles of the moon. First millions, then billions, of people will face an increasingly tough battle to survive. To find anything comparable we have to go back to the Pliocene – last epoch of the Tertiary period, 3m years ago. There were no continental glaciers in the northern hemisphere (trees grew in the Arctic), and sea levels were 25 metres higher than today’s. In this kind of heat, the death of the Amazon is as inevitable as the melting of Greenland. The paper spelling it out is the very one whose apocalyptic message so shocked in 2000. Scientists at the Hadley centre feared that earlier climate models, which showed global warming as a straightforward linear progression, were too simplistic in their assumption that land and the oceans would remain inert as their temperatures rose. Correctly as it would turn out, they predicted positive feedback. Warmer seas absorb less carbon dioxide, leaving more to accumulate in the atmosphere and intensify global warming. On land, matters would be even worse. Huge amounts of carbon are stored in the soil, the half-rotted remains of dead vegetation. The generally accepted estimate is that the soil carbon reservoir contains some 1600 gigatonnes, more than double the entire carbon content of the atmosphere. As soil warms, bacteria accelerate the breakdown of this stored carbon, releasing it into the atmosphere. The end of the world is nigh. A three-degree increase in global temperature – possible as early as 2050 – would throw the carbon cycle into reverse. Instead of absorbing carbon dioxide, vegetation and soils start to release it. So much carbon pours into the atmosphere that it pumps up atmospheric concentrations by 250 parts per million by 2100, boosting global warming by another 1.5C. In other words, the Hadley team had discovered that carbon-cycle feedbacks could tip the planet into runaway global warming by the middle of this century – much earlier than anyone had expected. Confirmation came from the land itself. Climate models are routinely tested against historical data. In this case, scientists checked 25 years’ worth of soil samples from 6,000 sites across the UK. The result was another black joke. As temperatures gradually rose the scientists found that huge amounts of carbon had been released naturally from the soils. They totted it all up and discovered – irony of ironies – that the 13m tonnes of carbon British soils were emitting annually was enough to wipe out all the country’s efforts to comply with the Kyoto Protocol.” All soils will be affected by the rising heat, but none as badly as the Amazon’s. “Catastrophe” is almost too small a word for the loss of the rainforest. Its 7m square kilometres produce 10% of the world’s entire photosynthetic output from plants. Drought and heat will cripple it; fire will finish it off. In human terms, the effect on the planet will be like cutting off oxygen during an asthma attack. In the US and Australia, people will curse the climate-denying governments of Bush and Howard. No matter what later administrations may do, it will not be enough to keep the mercury down. With new “super-hurricanes” growing from the warming sea, Houston could be destroyed by 2045, and Australia will be a death trap. “Farming and food production will tip into irreversible decline. Salt water will creep up the stricken rivers, poisoning ground water. Higher temperatures mean greater evaporation, further drying out vegetation and soils, and causing huge losses from reservoirs. In state capitals, heat every year is likely to kill between 8,000 and 15,000 mainly elderly people. It is all too easy to visualise what will happen in Africa. In Central America, too, tens of millions will have little to put on their tables. Even a moderate drought there in 2001 meant hundreds of thousands had to rely on food aid. This won’t be an option when world supplies are stretched to breaking point (grain yields decline by 10% for every degree of heat above 30C, and at 40C they are zero). Nobody need look to the US, which will have problems of its own. As the mountains lose their snow, so cities and farms in the west will lose their water and dried-out forests and grasslands will perish at the first spark. The Indian subcontinent meanwhile will be choking on dust. All of human history shows that, given the choice between starving in situ and moving, people move. In the latter part of the century tens of millions of Pakistani citizens may be facing this choice. Pakistan may find itself joining the growing list of failed states, as civil administration collapses and armed gangs seize what little food is left. As the land burns, so the sea will go on rising. Even by the most optimistic calculation, 80% of Arctic sea ice by now will be gone, and the rest will soon follow. New York will flood; the catastrophe that struck eastern England in 1953 will become an unremarkable regular event; and the map of the Netherlands will be torn up by the North Sea. Everywhere, starving people will be on the move – from Central America into Mexico and the US, and from Africa into Europe, where resurgent fascist parties will win votes by promising to keep them out. Chance of avoiding three degrees of global warming: poor if the rise reaches two degrees and triggers carbon-cycle feedbacks from soils and plants. Two – upticks in emissions causes ocean acidification – results in extinction. Huelsenbeck 13 (Matt Huelsenbeck is a marine scientist for the climate and energy campaign at Oceana; "Acid Test: Rising CO2 Levels Killing Ocean Life (Op-Ed)"; 7-16-2013; Live Science; http://www.livescience.com/38219-oceansacidifying-with-rising-co2.html; DT) The ocean absorbs approximately one-third of all human-caused carbon dioxide emissions at a rate of 300 tons per second, which helps slow global climate change. But, due to that carbon dioxide absorption, the ocean is now 30 percent more acidic than before the Industrial Revolution, and the rate of change in ocean pH, called ocean acidification, is likely unparalleled in Earth’s history. With today’s levels of atmospheric carbon dioxide so high, the ocean’s help comes at a cost to marine life and the millions of people who depend on healthy oceans. For the first time in human history, atmospheric carbon dioxide levels have risen above 400 parts per million (ppm) of carbon dioxide at the historic Mauna Loa Observatory in Hawaii. This observatory is where Scripps Institution of Oceanography researcher Charles David Keeling created the “Keeling Curve,” a famous graph showing that atmospheric carbon dioxide concentrations have been increasing rapidly in the atmosphere for decades. Carbon dioxide levels were around 280 ppm before the Industrial Revolution, when humans began releasing large amounts of the gas into the atmosphere by burning fossil fuels. On May 9, 2013, the reading was an alarming 400.08 ppm for a 24-hour period. This number would be even higher, however, if it were not for the help of the oceans. [Atmospheric Carbon Dioxide Breaks 3-Million-Year Record] Scientists already see ocean acidification harming marine animals like oysters, mussels and clams as well as coral reefs and floating marine snails called pteropods, dubbed the “potato chips of the sea” because of their significance to marine food webs. In the last decade, ocean acidification killed many oyster larvae at the Whisky Creek oyster hatchery in Oregon, shrunk the shells of pteropods in the Southern Ocean and slowed coral growth on Australia’s Great Barrier Reef. Society’s use of fossil fuels is putting the world’s marine life through a high-risk chemistry experiment with no fail-safes in place and no way to turn back. Earlier in Earth’s history, changes in ocean conditions that were much slower than today still managed to wipe out 95 percent of marine species. If emissions continue at current rates, our planet is risking a similar mass extinction event, one that could begin within our lifetimes. These impacts will ripple up to threaten people as well, who are at the top of the ocean food web. In September 2012, an Oceana report entitled “Ocean-Based Food Security Threatened in a High CO2 World” ranked nations based on their vulnerability to reductions in seafood production due to climate change and ocean acidification. Many island nations rely on seafood as one of their main food sources, since it is the cheapest and most readily available source of protein. Threats to seafood especially threaten small-scale fishermen, who simply aren’t capable of following fish into distant waters. Reducing carbon dioxide emissions is the only way to confront global ocean acidification and the primary means to stop climate change. Biodiversity loss is an impact filter – exacerbates existing crises and leads to extinction. Torres 16 (Phil is a graduate of Cornell University with degrees in Entomology and Biology; "Biodiversity Loss: An Existential Risk Comparable to Climate Change"; 5-20-2016; FLI - Future of Life Institute; http://futureoflife.org/2016/05/20/biodiversity-loss/; DT) Catastrophic consequences for civilization The consequences of this rapid pruning of the evolutionary tree of life extend beyond the obvious. There could be surprising effects of biodiversity loss that scientists are unable to fully anticipate in advance. For example, prior research has shown that localized ecosystems can undergo abrupt and irreversible shifts when they reach a tipping point. According to a 2012 paper published in Nature, there are reasons for thinking that we may be approaching a tipping point of this sort in the global ecosystem, beyond which the consequences could be catastrophic for civilization. As the authors write, a planetaryscale transition could precipitate “substantial losses of ecosystem services required to sustain the human population.” An ecosystem service is any ecological process that benefits humanity, such as food production and crop pollination. If the global ecosystem were to cross a tipping point and substantial ecosystem services were lost, the results could be “widespread social unrest, economic instability, and loss of human life.” According to Missouri Botanical Garden ecologist Adam Smith, one of the paper’s co-authors, this could occur in a matter of decades—far more quickly than most of the expected consequences of climate change, yet equally destructive. Biodiversity loss is a “threat multiplier” that, by pushing societies to the brink of collapse, will exacerbate existing conflicts and introduce entirely new struggles between state and non-state actors. Indeed, it could even fuel the rise of terrorism. (After all, climate change has been linked to the emergence of ISIS in Syria, and multiple high-ranking US officials, such as former US Defense Secretary Chuck Hagel and CIA director John Brennan, have affirmed that climate change and terrorism are connected.) The reality is that we are entering the sixth mass extinction in the 3.8-billion-year history of life on Earth, and the impact of this event could be felt by civilization “in as little as three human lifetimes,” as the aforementioned 2012 Nature paper notes. Furthermore, the widespread decline of biological populations could plausibly initiate a dramatic transformation of the global ecosystem on an even faster timescale: perhaps a single human lifetime. The unavoidable conclusion is that biodiversity loss constitutes an existential threat in its own right. As such, it ought to be considered alongside climate change and nuclear weapons as one of the most significant contemporary risks to human prosperity and survival. Climate change is more catastrophic than other impacts – evaluate probability times magnitude, historical precedence, and the fact that greater international action is needed to solve. Wagner & Weitzman 15 (Gernot Warner: Lead senior economist, Environmental Defense Fund; Martin L. Weitzman: Professor of economics, Harvard University; “How Does Climate Stack up against Other Worst-Case Scenarios?”; 4/1/2015; http://ensia.com/voices/how-does-climate-stack-up-against-other-worst-case-scenarios; DT) What we know about climate change is bad. What we don’t know makes it potentially much worse. But climate change isn’t the only big problem facing society. Opinions differ on what should rightly be called an “existential risk” or planetary-scale “catastrophe.” Some include nuclear accidents or terrorism. Others insist only nuclear war, or at least a large-scale nuclear attack, reaches dimensions worthy of the “global” label. There are half a dozen other candidates that seem to make it on various lists of the worst of the worst, and it’s tough to come up with a clear order of which most demands our attention and limited resources. In addition to climate change, let’s consider asteroids, biotechnology, nanotechnology, nukes, pandemics, robots and “strangelets,” strange matter with the potential of swallowing the Earth in a fraction of a second. That might strike some as a rather short list. Aren’t there thousands of potential risks? One could imagine countless ways to die in a traffic accident alone. That’s surely the case. But there’s an important difference: While traffic deaths are tragic on an individual level, they are hardly catastrophic as a class. Every entry on our list has the potential to wipe out civilization as we know it. All are global, highly impactful and mostly irreversible in human timescales. Most are highly uncertain. One response to any list like this is to say that each such problem deserves our (appropriate) attention, independently of what we do with any of the others. If there’s more than one existential risk facing the planet, we ought to consider and address each in turn. That logic has its limits. If catastrophe policies were to eat up all the resources we have, we’d clearly have to pick and choose. But we don’t seem to be anywhere close. A first step, then, should always be to turn to benefit-cost analysis, which in turn is something that every U.S. president since Ronald Reagan has affirmed as a guiding principle of government policy. Ideally, society should conduct serious benefit-cost analyses for each worst-case scenario: estimate probabilities and possible impacts, multiply the two, and compare it to the costs of action in each instance. If climate change and asteroids and biotechnology and nanotechnology and nukes and pandemics and robots and strangelets emerge as problems worthy of more of our attention, society should devote more resources to each. But we can’t just hide behind standard benefit-cost analysis that ignores extremes. Each of these scenarios may also have their own variant of “fat tails,” or underestimated and possibly unquantifiable extreme events that could dwarf all else. The analysis soon moves toward some version of a precautionary principle focused on extreme events. The further we move away from standard benefit-cost analysis, the more acute the need to compare across worst-case scenarios — a comparison that is getting increasingly difficult. How, then, to analyze these potential worst-case scenarios and decide which deserves more of our attention? For one, only two on the list — asteroids and climate change — allow us to point to history as evidence of the enormity of the problem. For asteroids, go back 65 million years to the one that wiped out the dinosaurs. For climate, go back a bit over 3 million years to find today’s concentrations of carbon dioxide in the atmosphere and sea levels up to 20 meters (66 feet) higher than today. Asteroids come in various shapes and sizes. We begin our book Climate Shock by looking at the one that exploded above Chelyabinsk Oblast in February 2013. The impact injured 1,500 and caused some limited damage to buildings. We shouldn’t wish for more of these impacts to happen just for the spectacular footage, but we’d be hard pressed to call an asteroid of that size a “worst-case scenario.” NASA’s attempts at cataloguing and defending against objects from space aims at much larger asteroids, the ones that come in civilization-destroying sizes. Astronomers may have been underestimating the likelihood of Chelyabinsk Oblast–size asteroids all along. That’s a problem that needs to be rectified, but it’s not a problem that will wipe out civilization. If we estimated the likelihood of a much larger impact incorrectly, the consequences could be significantly more painful. Luckily, when it comes to asteroids, there’s another feature working for us. Science should be able to observe, catalog and divert every last one of these large asteroids — if sufficient resources are provided. That’s a big if, but not an insurmountable one: A National Academy study puts the cost at $2 to $3 billion and 10 years’ research to launch an actual test of an asteroid deflection technology. That’s much more than we are spending at the moment, but the decision seems rather easy: Spend the money, solve the problem, move on. Strangelets are the opposite of the Chelyabinsk Oblast asteroid in that they have never been observed. They are straight out of science fiction and may be theoretically impossible. If it is possible, though, there may be a chance that large heavy-ion colliders like the one ramping up once again at CERN near Geneva could create them. That has prompted research teams to calculate the likelihood of a strangelet actually happening. Their verdict: Concrete numbers for the upper bound hover between 0.0000002 percent and 0.002 percent. That’s not zero, but it might as well be. So yes, swallowing the entire planet would be the ultimate bad — clearly worse, say, than melting the poles and raising sea levels by several meters or feet. Stranger things have happened. But strangelets very, very, very likely won’t. The same could be said of autonomous robots reproducing and taking over the world. It’s not that it can’t ever happen, but it certainly hasn’t happened before. That doesn’t mean it won’t, but if forced to put a probability on the eventuality, it would be very, very small. If we could rank worst-case scenarios by how likely they are to occur, we’d have taken a huge step forward. If the chance of a strangelet or robot takeover is so small as to be ignorable, probabilities alone might point to where to focus. But that’s not all. The size of the impact matters, too. So does the potential to respond. What then, if anything, still distinguishes climate change from the others remaining: biotechnology, nanotechnology, nukes and pandemics? For one, the relatively high chance of eventual planetary catastrophe. In Climate Shock, we zero in on eventual average global warming of 6 °C (11 °F) as the final cutoff few would doubt represents a true planetary catastrophe. Higher temperatures are beyond anyone’s grasp. Yet our current path doesn’t exclude eventual average global warming above 6 °C. In fact, our own analysis puts the likelihood at around 10 percent, and that’s for an indisputable global catastrophe. Climate change would trigger plenty of catastrophic events with temperatures rising by much less than 6 °C. Many scientists would name 2 °C (3.6 °F) as the threshold, and we are well on our way to exceeding that, unless there is a major global course correction. Second, the gap between our current efforts and what’s needed on climate change is enormous. We are no experts on any of the other worst-case scenarios, but there at least it seems like much is already being done. Take nuclear terrorism. The United States alone spends many hundreds of billions of dollars each year on its military, intelligence and security services. That doesn’t stamp out the chance of terrorism. Some of the money spent may even be fueling it, and there are surely ways to approach the problem more strategically at times, but at least the overall mission is to protect the United States and its citizens. It would be hard to argue that U.S. climate policy today benefits from anything close to this type of effort. As for mitigating pandemics, more could surely be spent on research, monitoring and rapid response, but here too it seems like needed additional efforts would plausibly amount to a small fraction of national income. Third, climate change has firm historical precedence. There’s ample reason to believe that pumping carbon dioxide into the atmosphere is reliving the past — the distant past, but the past nonetheless. The planet has seen today’s carbon dioxide levels before: over 3 million years ago, with sea levels some 20 meters higher than today, and camels roaming the high Arctic. There are considerable uncertainties in all of this, but there’s little reason to believe that humanity can cheat basic physics and chemistry. Contrast the historical precedent of climate change with that of biotechnology, or rather the lack of it. The fear that bioengineered genes and genetically modified organisms will wreak havoc in the wild is a prime example. They may act like invasive species in some areas, but a global takeover seems unlikely, to say the least. Much like climate change, historical precedent can give us some guidance. But unlike climate change, that same historical precedent gives us quite a bit of comfort. Nature itself has tried for millions of years to create countless combinations of mutated DNA and genes. The process of natural selection all but guarantees that only a tiny fraction of the very fittest permutations has survived. Genetically modified crops grow bigger and stronger and are pesticide-resistant. But they can’t outgrow natural selection entirely. None of that yet guarantees that scientists wouldn’t be able to develop permutations that could wreak havoc in the wild, but historical experience would tell us that the chance is indeed slim. In fact, the best scientists working on biotechnology seem to be much less concerned about the dangers of “Frankenfoods” and GMOs than the general public. The reverse holds true for climate change. The best climate scientists appear to be significantly more concerned about ultimate climate impacts than the majority of the general public and many policy makers. That alone should give us pause. Some of these same climate scientists — knowing what they know about the science, and knowing what they know about human responses to the climate problem — seem to have moved on. And they haven’t moved on to analyzing any of the other worst-case scenarios, believing that climate isn’t all that bad. Quite the opposite: Some have moved on to looking for solutions to the climate crisis in an entirely different realm, searching for anything that could pull the planet back from the brink of a looming catastrophe. Their focus: geoengineering. That, more than anything, should lead us to put the climate problem in its proper context. Climate is not the only “worst-case scenario” imaginable. Others, too, deserve more attention. But none of that excuses inaction on climate. And more importantly, there’s perhaps no other problem where the probability of disaster multiplied by the magnitude of disaster is as high as with climate. Contention 2: Solvency Plan: The United States Federal Government should offer the People’s Republic of China to launch the U.S.-China Partnership on Energy and Climate Change. The plan solves – a US-China led effort is key to kick-start a global effort on Climate Change. Holbrooke et. al 09 (Initiative for U.S.-China Cooperation on Energy and Climate, a partnership between: Asia Society Center on U.S.-China Relations (Richard Holbrooke, Chairman; Vishakha Desai, President; Orville Schell, Arthur Ross Director; Banning Garrett, Director, Initiative for U.S.-China Cooperation on Energy and Climate; Joanna Lewis, Initiative Research Director, Assistant Professor, Georgetown University School of Foreign Service; Jonathan Adams, Initiative Assistant Director) and Pew Center on Global Climate Change (Eileen Claussen, President; Elliot Diringer, Vice President, International Strategies; Steven Chu, Director, Lawrence Berkeley National Laboratory, Professor of Physics and Molecular and Cellular Biology, University of California, Berkeley*; John Thornton, Chairman, The Brookings Institution, Professor, Tsinghua University, Board Member, Asia Society) with help from The Brookings Institution: Kenneth Lieberthal and David Sandalow, Council on Foreign Relations: Elizabeth Economy and Michael Levi, Environmental Defense Fund: Peter Goldmark and David Yarnold, and National Committee on U.S.-China Relations: Steve Orlins and Jan Berris; Common Challenge, Collaborative Response; “A Roadmap for U.S.-China Cooperation on Energy and Climate Change”; January 2009; http://e360.yale.edu/images/features/us-china-roadmap.pdf; DT) A new comprehensive program for cooperation between the United States and China that focuses on reducing greenhouse gas emissions, and thus mitigating the potentially catastrophic effects of climate change, is both necessary and possible. Indeed, as this Report suggests, if human beings hope to avoid the worst consequences of global climate change, the United States and China—respectively the world’s largest developed and developing nations, the two largest energy consumers, and the two largest producers of greenhouse gases—have no alternative but to become far more active partners in developing low-carbon economies. To prevail in such a common effort, both countries will need not only bold leadership and a new set of national policies, but also a path-breaking cooperative agenda that can be sustained over the long run. The advent of a new U.S. presidential administration in Washington, D.C., coupled with a central leadership in Beijing that is increasingly aware of the destructive impact and long-term dangers of climate change, presents an unparalleled opportunity for this new strategic partnership. While the current global economic crisis could make joint action between the United States and China more difficult, it could also provide an unexpected impetus. If wisely allocated, funds invested by both governments in economic recovery can help address climate change while also advancing the “green technologies” and industries that will lead to a new wave of economic growth. Stronger bilateral collaboration on energy and climate change has at the same time the real prospect of helping to build a new, more stable, and constructive foundation under Sino-American relations, the most important bilateral relationship in the 21st century world. This Report—which was produced in partnership between Asia Society’s Center on U.S.-China Relations and Pew Center on Global Climate Change, in collaboration with The Brookings Institution, Council on Foreign Relations, National Committee on U.S.- China Relations, and Environmental Defense Fund—presents both a vision and a concrete Roadmap for such Sino-U.S. collaboration. With input from scores of experts and other stakeholders from the worlds of science, business, civil society, policy, and politics in both China and the United States, the Report, or “Roadmap,” explores the climate and energy challenges facing both nations and recommends a concrete program for sustained, high-level, bilateral engagement and on-the-ground action. The Report and its recommendations are based on the following understandings: That because there is overwhelming scientific consensus that human-induced climate change is well underway and poses grave economic and environmental risks to the world, the United States and China need to immediately begin acting in concert, without awaiting new domestic legislation or multilateral agreements, to jointly seek remedies for their emissions of greenhouse gases. That because climate change is largely a consequence of soaring global use of fossil fuels, addressing the problem will require a fundamental transformation of energy systems in both countries, as well as worldwide, through the development and deployment of new technologies and the widespread introduction of new energy sources capable of enhancing the diversity, reliability, independence, and “greenness” of national energy supplies. That even during a time of global economic upheaval, a strong bilateral effort to address the twin challenges of climate change and energy security can succeed while also contributing to economic recovery and laying the foundation for a prosperous, new, low carbon economy in each country. That a meaningful U.S.-China partnership on climate change issues can be forged on the basis of equity, taking into account the respective stages of development, capacities, and responsibilities of each country. That while enhanced U.S.-China cooperation must begin with collaboration between the two national governments, success will ultimately hinge on each nation’s ability to catalyze action and investment in the marketplace. That if fashioned carefully, closer collaboration on energy and climate can address the problem of climate change and enhance the economic prospects of both nations while conferring on neither an unfair competitive advantage. That by demonstrating global leadership and making significant new progress toward closer bilateral cooperation, the world’s two largest economies will help achieve stronger multilateral agreement and action under the United Nations (UN) Framework Convention on Climate Change. The Report recommends that, as a first step in forging this new partnership, the leaders of the two countries should convene a leaders summit as soon as practically possible following the inauguration of Barack Obama to launch a “U.S.-China Partnership on Energy and Climate Change.” This presidential summit should outline a major plan of joint-action and empower relevant officials in each country to take the necessary actions to ensure its implementation. The Report recommends that the partnership be directed by two parallel groups. A U.S.- China high-level council would be established to draw up overall plans for the collaboration. The Commission would include high-ranking environment, energy, and finance officials from both countries. It would meet regularly to establish and review the strategic direction of the new partnership as well as to discuss other issues of common concern, including those relating to ongoing multilateral negotiations. In addition, each of the highlighted concrete priority areas proposed below would be guided by a second tier of bilateral task forces. These would be composed of senior government officials and independent experts in science, technology, business, finance, civil society, and policy from each country. Their responsibilities would involve establishing goals, designating joint-research areas, developing collaborative programs within each of the designated areas, organizing concrete joint projects in each area of cooperation, and overseeing the implementation of these projects. Areas where direct collaboration is expected to yield the quickest and most substantial results on reducing greenhouse gas emissions have been given highest priority. They are listed below in shortened form, but discussed in greater detail in Section IV. Priority areas of collaboration include: - Deploying LowEmissions Coal Technologies. The likelihood that both the United States and China will continue to rely heavily on coal for many years to come necessitates immediate and large-scale investments in the research, development, and deployment of new technologies for the capture and sequestration of carbon emissions from coal-fired power plants. - Improving Energy Efficiency and Conservation. Both the United States and China have significant potential to lower their carbon emissions through low-cost, and even no-cost, energy efficiency and conservation measures that would have considerable impact on each country’s “carbon footprint” and energy security. - Developing an Advanced Electric Grid. Both the United States and China rely on outdated, decentralized, and inefficient electrical transmission systems. Both countries could profit from research, development, and adoption of new “smart grid” technologies capable of enabling these systems to handle larger quotients of low-carbon energy from episodic, but renewable sources of power more cheaply and efficiently. - Promoting Renewable Energy. There is an obvious need for both countries to develop a far broader deployment of solar, wind, and other renewable sources of energy in order to de-carbonize their respective electricity systems, expand their low-carbon economies, and thereby diminish their carbon emissions per unit of GDP. - Quantifying Emissions and Financing Low-Carbon Technologies. To help facilitate cooperation in the above areas, it will be important to continue to jointly address the crosscutting issues of quantifying and projecting emissions, and financing technology development and deployment. That our planet is now approaching a point of no return on the question of global warming is increasingly self-evident. Recognition of the daunting challenges that such moments pose can be unsettling, even paralyzing. However, with bold leadership, they can also be galvanic. It is unclear as yet whether the growing awareness of our tipping point moment will intersect in a timely manner with the new leadership that is now assuming office in Washington and the increasingly well-informed central leadership in Beijing to catalyze both countries toward mustering the necessary clarity of vision, intellectual resources, funding, technology, and international cooperation. What is clear, however, is that we are in uncharted waters that will beg an unprecedented effort from both the world at large and the United States and China in particular. For whether we choose to recognize it or not, these two countries are both crucial in the effort to address climate change. Simply put, if these two countries cannot find ways to bridge the long-standing divide on this issue, there will literally be no solution. Fortunately, it is the firm conviction of those who have worked on this Report over the past year that the United States and China will both benefit from the kind of collaboration outlined herein. Moreover, not only would such a collaboration allow the world to take a giant step forward in confronting the global climate change challenge, but both the United States and China would indirectly stand to profit immeasurably from it. If their leaders jointly play their cards astutely, the two countries could find themselves in the forefront of a new green-tech economy, and in a stronger, more strategic partnership, better able to help lead the world to meet other 21st century challenges. This Report presents both a vision and a concrete Roadmap for this new collaboration. With input from scores of experts, stakeholders, and policymakers from the worlds of science, business, civil society, policy, and politics in China and the United States, the Report explores the climate and energy challenges facing both nations and recommends a program for sustained high-level engagement and on-the-ground action. The Report and its recommendations are based on the following understandings: Action is Urgent. The United States and China should start now. There is overwhelming scientific consensus that human-induced climate change poses grave economic and environmental risks. Minimizing these risks requires that global greenhouse gas emissions, now rising at an unprecedented rate, peak as soon as possible and decline dramatically over the coming decades. Accomplishing this goal will be feasible only through concerted and sustained action, beginning immediately. The United States and China should not await new domestic legislation or multilateral agreements before launching stronger collaborative efforts. A Path to Energy Security. Climate change is largely a consequence of soaring global energy use, and addressing it requires a fundamental transformation of energy systems worldwide. This transformation presents an unparalleled opportunity to simultaneously address the urgent energy security challenges confronting the United States, China, and other nations by introducing new sources and technologies capable of enhancing the diversity, reliability, and independence of national energy supplies. New Economic Opportunity. At a time of global economic upheaval, strong efforts to address the twin challenges of climate change and energy security can contribute to economic recovery, while laying the foundation for a prosperous new low-carbon economy. The near-term investments that are needed will produce substantial long-term dividends through sustainable growth and employment. Conversely, delaying these investments will risk severe economic harm and drive up the cost of minimizing the impact of climate change. Common but Differentiated Responsibilities. As a point of departure, an equitable partnership must be built on a shared understanding of respective responsibilities and capacities. As the world’s largest economy and largest historic greenhouse gas emitter, the United States must demonstrate leadership by moving swiftly to reduce its emissions through mandatory national legislation. Although China has now surpassed the United States as the world’s largest annual emitter, its cumulative and per capita emissions are much lower, and development and poverty reduction will remain overriding national priorities for the foreseeable future. Having adopted a comprehensive national climate change program, National Climate Change Program, and agreed on the need to reduce its emissions below “business as usual,”China must now deliver an ambitious and effective national effort.2 PublicPrivate Engagement. While enhanced U.S.-China cooperation must begin with collaboration between the national governments, success will hinge on each nation’s ability to catalyze action by the private sector. Technology can be advanced, financing secured, and critical obstacles overcome only through a combination of bold leadership, ingenuity, expertise, and the mustering of the resources of leading investors, financial institutions, and companies in both the United States and China. But governments will play a critical role in creating the regulatory environment for large-scale private investment in and commercialization of low-carbon technologies through a wide range of tools, from tax incentives and subsidies to regulations and research. Cooperating while Competing. Fear of competitive harm has for too long stood as an obstacle to strong climate action. Competition can also be an engine for innovation and low-carbon growth. Under any scenario, companies and industries in the United States and China will remain vigorous economic competitors in the global marketplace. Fashioned carefully, closer collaboration on energy and climate can enhance the economic prospects of both nations while conferring on neither an unfair competitive advantage. Bilateral Means to Multilateral Ends. Climate change requires a global response, and stronger bilateral cooperation between the United States and China must contribute to, not deter, an effective multilateral climate agreement. By demonstrating global leadership and achieving bilateral practical progress, two of the[y] world’s largest economies can help all nations achieve fair and comprehensive agreements under the UN Framework Convention on Climate Change and beyond as envisioned in the Bali Action Plan. Past diplomatic initiatives failed because they had no enforcement mechanism and were all too small to have any impact – a US-China partnership is uniquely key to solve. Reynolds 6/30 (Ben Reynolds is a writer and foreign policy analyst based in New York; "Climate Change Outcomes of the 2016 Strategic and Economic Dialogue"; 6-30-2016; China US Focus; http://www.chinausfocus.com/finance-economy/climate-change-outcomes-of-the-2016strategic-and-economic-dialogue/; DT) Many of the new climate change-related developments within the Strategic and Economic Dialogue emerged from the “Second U.S.-China Climate-Smart / Low-Carbon Cities Summit.” The Summit brought U.S. and Chinese policymakers and private sector leaders together to establish cooperative relationships to address the challenges posed by climate change. This year, leaders of 66 U.S. and Chinese municipalities endorsed the Summit’s “ China U.S. Climate Leaders Declaration,” verbally committing to reporting greenhouse gas emissions, establishing emissions targets, and expanding their cooperative efforts with other municipal leaders. While the Declaration includes a number of commitments from states and cities in the U.S. and China to both monitor and reduce their greenhouse gas emissions, it makes no mention of any mechanism to ensure that the signatories live up to their statements. Previous climate accords have always struggled with the difficulties of enforcing climate targets that are often conveniently forgotten after big summits. In 2011, Bulgaria, Romania, and Ukraine were suspended from the Kyoto Protocol’s cap and trade markets due to inaccurate reporting of greenhouse gas emissions. When Canada faced penalties for its failure to meet emissions targets that same year, it simply pulled out of the Kyoto Protocol altogether. It remains to be seen whether the signatories of this year’s Declaration will actually comply with their commitments absent any sort of enforcement mechanisms. The Summit featured the signing of a number of interesting agreements between various public and private sector actors, a relatively rare concrete outcome of the S&ED. The cities of Los Angeles and Lanzhou agreed to partner in their attempts to promote clean energy, transportation, and buildings. WRI China and the C40 Cities Climate Leadership Group committed to help Wuhan and Shenzen, a major industrial center, develop greenhouse gas emissions inventories. PowerFlame, a U.S. company, and Beijing’s Municipal Environmental Protection Bureau agreed to conduct a pilot project to evaluate the use of U.S. burner technologies as a means to reduce air pollution from gas-fired boilers in Beijing. This list is not exhaustive, but all of the initiatives provide examples of commitments to concrete cooperative partnerships between actors in China and the United States. At this year’s S&ED, the U.S. and China launched a new effort under the Climate Change Working Group on Power Consumption, Demand, and Competition to increase the use of renewable energy in China. The irony of this effort is palpable. China is already the world’s largest market for solar panels, and the U.S. has levied steep tariffs on solar panel imports from Chinese manufacturers to protect its domestic industries. One of the best ways the U.S. could encourage the adoption of solar panels would be the removal of these tariffs, which hike the price of solar panels for U.S. consumers. Finally, the U.S. and China reiterated their commitment to the “Race to Zero Emissions” initiative, which is designed to encourage the deployment of zero-emissions buses in American and Chinese cities. U.S. transit agencies currently operate only around 300 zero emissions buses, while China operates at least 1,600 zero emissions buses and over 15,000 alternative fuel buses. The U.S. federal government currently offers modest subsidies to encourage local transit authorities to adopt zero emissions buses, but adoption could likely be greatly improved with a more generous contribution. The various initiatives detailed above are all relatively modest, but they represent small, productive steps toward the establishment of sustainable societies in China and the United States. If anything, these steps are better than nothing – they at least represent a minor commitment to meet the emissions targets established by the U.S. and China at the Paris Agreement. As I have previously argued, even if every country in the world were to religiously stick by its pledges under the Paris Agreement, we would still fail to prevent potentially catastrophic global warming within the 21st century. It is obvious that a more radical restructuring of the global economy is necessary, but we have to start somewhere. More than anything, the challenge of climate change should highlight the absolute necessity of U.S.-China cooperation and the extraordinary dangers of a deepening rivalry. Climate change poses a potentially existential threat to contemporary society. The U.S. and China are the world’s two largest emitters of carbon dioxide, and some scientists have suggested that a strong enough pact between the two countries would be enough to put the world back on track to relative climate stability. But the changes necessary to achieve climate stability will require painful compromises and sacrifices, neither of which will be feasible if the world’s largest emitters view each other with suspicion. The strategic rivalry between the U.S. and China continues to deepen, and this trend seems likely to continue under a presumptive Clinton administration. Yet, because of the challenge of climate change, we need the U.S. and China to embrace unprecedented levels of cooperation now more than ever. There are few historical examples of the leaders of competing great powers embracing peaceful cooperation to secure the common good. It will take a serious reorientation to ensure that we place the fate of our children before the struggle for hegemony. The Paris Agreements do very far from enough to solve global warming—most countries’ timelines regarding implementing the Paris Talks do not stretch beyond 2030, and many have no timeline of implementation at all.

She has won several awards for her work in the Middle East, and in 2003 covered the US invasion of Iraq from Baghdad. She is author of Madam President, about Hillary Clinton's historic run for White House. April 22nd, 2016. “Why the Paris climate change goals may already be slipping beyond reach”, theGuardian. https://www.theguardian.com/environment/2016/apr/22/paris-climate-agreement-unitednations] World leaders have failed to come to grips with the epic challenge of phasing out fossil fuels and running the entire global economy almost entirely on clean energy by the middle of this century, experts said this week. While more than 170 countries converged at the United Nations on Friday to demonstrate their support for the landmark deal to fight climate change reached at Paris last December, economists and scientists warned the accord’s goal of keeping temperatures below 1.5-2C may already be slipping beyond reach. So far, the commitments covered by the Paris agreement would allow warming of about 2.7C, according to the UN’s own estimates – which would unleash rising seas, extreme heat and other upheavals. “While we should be celebrating the signing ceremony on Friday we need to be aware of the gap, where the current contributions add up to and where we need to go,” said Shane Tomlinson, a senior research fellow in energy and climate change at Chatham House. Countries have to operate on two distinct time lines as they put the promises of Paris into action. First is the next five years, when they will need to radically increase emissions cuts to avoid locking out a 2C future.Second is the long term, when they must put plans in place for a late 21st-century economy powered almost entirely by clean energy, the experts said. The US – despite Barack Obama’s strong advocacy for climate action and a flurry of climate initiatives over the past two and a half years – has yet to engage in the long-term thinking needed for a historic economic transition, according to Jeffrey Sachs, director of Columbia University’s Earth Institute and a special advisor to Ban Ki-moon. “Why is it that with an administration that is gung-ho on climate we are in the eighth year and there is no plan at all? No sketch, no white paper, no scenario to 2050?” Sachs told a gathering this week. Most countries’ plans do not look beyond 2030 – despite agreement in Paris to begin phasing out greenhouse gas emissions completely by the middle of the century. Planning for a zero-carbon economy by mid-century demands long lead times, decades even, because it involves major decisions about power plants and transmission lines, building codes and vehicle standards, Sachs said. But most countries were still not looking as far down the road as 2050 – including the US. Obama, despite a flurry of climate initiatives since 2013, had yet to produce a coherent longterm plan for a 21st-century post-carbon economy, Sachs said. At the start of his presidency, Obama pledged to cut greenhouse gas emissions 80% by 2050. “The goal has been around since the beginning of the Obama administration. But as far as I know you can’t find out even one document that sketches out how this would be accomplished,” Sachs said. The near-universal support for the Paris agreement would avoid the backsliding that followed the Kyoto protocol of the 1990s, experts said. But the very nature of the deal – which gained widespread support precisely because its decentralised structure allows countries to set their own emissions cutting targets – makes it difficult to make big changes fast. Leaders would need the support of business and campaign groups to turn economies around swiftly. Some countries, including the US, face multiple challenges to their leaders’ efforts to cut emissions. Obama’s rules cutting carbon pollution from power plants face a legal challenge from states and industry groups. Donald Trump, the leading Republican presidential candidate, has expressed doubts even about the existence of climate change. China and India, while committing publicly to cut emissions, have also cracked down on campaign groups that would keep them to account, Tomlinson said. And climate pollution continued to rise in the 25 years it took negotiators to reach a deal. “The problem is that over the last decade we haven’t decarbonised our energy system. We have carbonised our energy system,” said Ottmar Edenhofer, chief economist at the Potsdam Institute for climate change research. Countries needed to radically ramp up ambition now – before 2020 – to avoid locking out the future of a 2C future, he said. If countries wait until 2030, the date envisaged in the Paris agreement, they would have to cut global emissions by 6% a year to keep the 2c goal in sight. “The longer we wait for effective climate policy, the more severe and the more traumatic will be the emissions reductions in the future,” he said. China will say yes – wants to establish a larger leadership role in terms of climate agreements. Hart 15 (Melanie Hart is a Senior Fellow and Director of China Policy at American Progress; "Assessing American Foreign Policy Toward China"; 9-29-2015; Center for American Progress; https://www.americanprogress.org/issues/security/report/2015/09/29/122283/assessingamerican-foreign-policy-toward-china/; DT) China’s new assertiveness creates new opportunities and new challenges for the United States. On the positive side, China is showing an increasing willingness to play a leadership role among nations outside the highly industrialized democratic block. China played a key role in the Iran nuclear negotiations, helping the process through shaky moments, and Chinese nuclear experts helped Iranian officials redesign the Arak plutonium reactor so that it will never produce nuclear fuel. On climate change, China’s willingness to issue bold climate targets with the United States last November challenged other developing nations to follow suit and knocked down a firewall that has hindered global climate negotiations for decades. China also appears to be leaning harder on North Korea. China supported the U.N. Security Council effort to sanction North Korea in response to that nation’s February 2013 nuclear test. Earlier this month, after North Korean officials announced plans to launch another long-range rocket, China’s foreign minister warned against “taking new actions that could lead to tensions” on the Korean peninsula and called for all nations to take a “responsible attitude.” On all of these issues, Beijing’s ability to speak to a different audience and from a different angle than the United States has made China a valuable diplomatic partner. Cooperation between the US and China will influence other countries to pledge emissions reductions – without the plan, countries won’t be on board. Stone 15 (Jessica Stone is a Washington Correspondent focusing on American politics, trade, and economics coverage; “China US cooperation crucial on global climate change”; CCTV America; http://www.cctv-america.com/2015/11/29/china-us-cooperation-crucial-on-globalclimate-change; DT) Wang Pu, a climate researcher at Harvard, said China’s commitment fits into its economic goals of reducing reliance on coal-powered manufacturing and moving to a services and technology-led economy that pollutes less, and emphasizes renewables. “I would say China is definitely one of the most important actors,” Wang said. “Climate policy is viewed by the Chinese government as both environmental and economic policy. I think it’s a win-win solution for environment and for the economy.” And win-win for China s relationship with the United States. Wang says finding common ground with Americans on climate policy is also a way to manage diplomatic differences. For the U.S., Chinese cooperation is essential to achieving a goal of President Barack Obama’s: slowing climate change, according to Elliot Diringer of the Center for Climate and Energy Solutions. “Unless both the U.S. and China are really committed to this, it’s very hard to get other countries to come along,” Diringer said. “I think the U.S. administration certainly recognized that and has worked really hard to reach out to China.” “I think China did set an example for these other emerging economies, particularly for India,” Pu said. “I think China has had some indirect influence over India decision to make their own national contributions.” Many experts also believe nations around the world are watching to see if and how the U.S. reaches its reduction targets. The U.S. has already reduced vehicle emissions and is now focusing on cutting emissions from power production, the largest source of carbon pollution nationwide. “That is a huge example to the rest of the world, that this is a challenge that can be met without sacrificing economic growth and development,” Diringer said. Beijing doubts whether the U.S. political system will allow it to accept any binding climate agreement. And Washington has reason to doubt whether Beijing will accept emissions transparency standards or commit to set new reduction goals every five years. But both have moved closer on other aspects of the climate negotiations. During Chinese President Xi Jinping’s U.S. state visit in September, China matched the U.S. contribution of nearly $3 billion to help developing countries combat climate change. And perhaps its greatest impact, aside from reducing its own carbon footprint, will be to inspire other major economies to pledge ambitious reduction targets. Heading into the Paris climate talks, U.N. Secretary General Ban Ki-moon said current commitments don’t achieve the goal of holding the increase in global temperature to two degrees Celsius. The U.S. and China in particular will need to use their influence to enlist the help of other countries during the negotiations to change that. Contention 3: Framing To succumb to the disguise of time is a fatal mistake—we cannot let global warming lull us into a feeling of false security. Guth 07 (Dr. Joseph H. Guth: Legal Director of the Science & Environmental Health Network, PhD in Biochemistry from University Of Wisconsin and JD from NYU; “LAW FOR THE ECOLOGICAL AGE”; Vermont Journal of Environmental Law; 9 Vt. J. Envtl. L. 431; Winter 20072008; http://sehn.org/wp-content/uploads/2013/01/VJEL10068.pdf; DT) The central presumption of the common law that environmental damage can be economically justified can be true only so long as the world is “empty.” It becomes false when the world is “full,” when cumulative environmental damage exceeds the capacity of the Earth to assimilate it. Thus, the belief of Justices Livingston and Holmes that economic activity tends to benefit the public will not always be true. Once we overshoot the Earth’s assimilative capacity, and begin to devastate the ecological systems on which we depend, the law can no longer justify a starting presumption that economic activity furthers the public welfare even where it causes ecological damage. Moreover, under these conditions, cost–benefit analysis can no longer be justified as a tool for evaluating the reasonableness of individual increments of environmental damage. Each incremental impact, if taken alone, might have caused little or even no harm at all in an empty world. But under conditions of ecological overshoot each increment of damage contributes to an immeasurable, indeed infinite, loss. This infinite loss cannot be meaningfully allocated among the various increments of damage. Once we are degrading the environment at an unsustainable rate, attempting to justify increments of damage using cost–benefit principles is profoundly misguided and represents a denial of the biological realities of life on the Earth. Under conditions of ecological overshoot, the core structure of the modern common law cannot be justified as one that furthers the public welfare. At that point, it is no longer legitimate as an American rule of law. Apocalyptic representations are necessary to mobilize support to solve warming – this sense of moral urgency results in an ecological ethic. Harvard 13 ("Social Movements and Climate Change"; 6-17-2013; Harvard University Center for the Environment; http://environment.harvard.edu/news/huce-headlines/social-movementsand-climate-change; DT) On the climate issue, the problem is that “urgency is not felt by many people,” says Marshall Ganz, a senior lecturer at Harvard Kennedy School. “But one thing that movements do is come up with ways to make the important urgent.” Ganz speaks from experience. He left Harvard during his junior year to work with the civil rights movement in Mississippi in 1964. He went on to work with Cesar Chavez and the United Farm Workers for 16 years, before eventually returning to Harvard to complete a Ph.D. in sociology. One of the lessons he draws from his decades working in and studying social movements is that moral urgency—a sense of injustice, or even anger—is often needed to move individuals to act. This is often accompanied by hope, or the sense of the plausible, the possible. Action of this kind may produce change in the participants themselves, as well as in the world around them. “If you look at the core of any social movement there are highly committed people who are ready to take risks,” he says. “It’s not just about passing a law—at heart they are movements of moral reform. Take the Harvard living wage campaign back in 2001, when the students sat in the president’s office and said, ‘We’re not going to leave until it gets dealt with.’” This had the effect of turning what the students saw as a morally urgent problem into a practically urgent problem for decision-makers to resolve. “How to make that cosmic sense of urgency immediately felt is one of the challenges of this (climate) movement,” Ganz continues. “That’s where civil disobedience and that kind of activity comes in—it’s a way of saying we’re not going to cooperate until you address this need.” Ganz met recently with a group of law school students seeking advice on the campaign to press Harvard’s administration to divest from fossil fuel companies. He says he supports the students’ efforts on the merits of their moral argument, but also as a means to stir up and “[that] mobilize the kind of movement it will take to make broader and deeper change.” “There is a very strong generational dynamic to this whole thing,” Ganz says. “Generation change is one of the great drivers of cultural and political change. Bill McKibben [’82] gets that, which is why he has this focus on divestment: give the rising generation a strategic focus.” War is not an impact – 1. This is the 21st century – major wars are obsolete – diplomacy, demilitarization, and political psychologies. Sangha 11 (Karina: BA in Political Science from the University of Victoria; “The Obsolescence of Major War: An Examination of Contemporary War Trends”; Vol 5, No 1: Spring 2011; http://web.uvic.ca/~onpol/spring2011/Two%20-%20Sangha.pdf; DT) Since the end of the Second World War, direct conflict among the great powers has been seemingly non-existent, marking the longest absence of major war since the days of the Roman Empire.8 Given the scale and frequency of major war in previous centuries, this absence may be the single most important discontinuity that the history of warfare has ever seen.9 Though not without tension, great power relations are now generally characterized by a sense of peace, with states carrying out aggressions through diplomatic or economic, rather than military, means. Indeed, as the threat of major war has declined, most great powers have chosen to invest fewer resources in developing a strong military, undergoing a notable downsizing in both the size of their armed forces and the quantity of weapons at their disposal since 1945.10 While most great powers had possessed forces numbering several million men throughout much of the twentieth century, as of the late 1990s, the only states maintaining forces exceeding a million and a half were India and China, and at that time, China had announced it would be cutting half a million of its troops.11 In addition to directly cutting their forces, most states have also eliminated conscription, a once useful system that provided a great deal of cannon fodder for the institution of major war.12 Air forces, naval forces, and nuclear weapons stores have also witnessed similar reductions worldwide.13 Indicative of the current sense of great power peace, these reductions would also seem to imply that none of the great powers anticipates a major war to break out any time in the near future, supporting the idea that major war is becoming obsolete. However, having said this, it is important to note that, in and of itself, the extended absence of major war is a necessary, but not a sufficient, criterion for the obsolescence of major war. In fact, it is arguable that the current absence is not an indication of the institution’s obsolescence, but simply a temporary period of peace within the broader cycle of major war, a cycle linked to the rise and fall of world orders.14 On this view, international stability is tied to the presence of a hegemon that is capable of maintaining order in an anarchic international system due to its economic and military supremacy. 15 When such hegemony is challenged by a rising power, this theory asserts that major war is likely to break out as power becomes more equally distributed and the control maintained by the hegemon is lost.16 Thus, just as the hegemonic presence of Great Britain ushered in a period of peace during the nineteenth century, it would seem that the prolonged peace we are currently witnessing may be attributable to the dominance of the United States in the contemporary international system, a dominance that remains open to challenge, particularly by rising powers like China and India. In this sense, instead of indicating its obsolescence, the current absence of major war may simply be a temporary manifestation of American hegemony that will inevitably be challenged and lost in the future, thus continuing the cycle of major war.17 Though not entirely devoid of merit, one should be wary of accepting this argument. Historically, some periods of hegemony have witnessed a general sense of peace among the great powers, but this does not mean that international stability is inherently tied to a unipolar structure. Indeed, many studies find little to no connection between power configurations and the incidence of war in the international system.18 Nonetheless, even if it can be accepted that war has been cyclical in the past, tied to changing power balances, economic waves, or otherwise, this need not imply that this cycle must continue, thereby discounting the thesis at hand. Even if the current period of peace is temporary, trends surrounding the frequency of major war for the past few centuries seem to indicate that such periods are becoming increasingly more frequent and may one day become the established norm. In fact, extrapolating from the works of individuals like J.S. Levy and Evan Luard, both of whom have performed analyses as to the frequency of major war, it is arguable that the absence we are seeing today has been taking shape for centuries, with periods of great power peace growing in both frequency and length. Focusing on various periods between the fifteenth and nineteenth centuries, both Levy and Luard find the nineteenth century to be the most peaceful, followed by the twentieth, the eighteenth, the sixteenth, and the fifteenth centuries, with the seventeenth century appearing the most warlike.19 Undeniably, the placement of the twentieth century in this sequence is problematic, though understandable given the spans of time these two scholars were considering. In 1984, the last year examined by Luard’s study, great power peace would have lasted for just under forty years, placing the twentieth century neatly between the nineteenth and eighteenth centuries, which Luard records as having seen fortythree and twenty-seven years of continuous peace, respectively.20 However, in light of the fact that the twentieth century saw no major wars between 1945 and its conclusion, exhibiting fifty-five years of peace that continues today, the twentieth century should arguably be readjusted in both Luard’s and Levy’s analysis as the most peaceful of those studied. Once this is done, it would seem that, with some exceptions, these analyses reveal an increasing tendency towards peace among the great powers, indicating that the current absence of major war may be the cementation of a trend that has been developing for centuries. Thus, if there is a cycle to major war, it would seem that we are witnessing its conclusion. The significance of the current absence of major war cannot be stressed enough. And yet, while significant, it is important to note that the years following the Second World War have not been marked by absolute peace, not even for the great powers. Shortly after the conclusion of the Second World War, the Cold War broke out, a contest between the Soviet Union and the United States that would define the next few decades of history. Although most of the wars fought during this period took place in the Global South, the Soviet Union, the United States, and their respective allies often participated in these battles, providing logistical support or even their own military forces. These proxy wars, wherein powerful countries utilized civil conflicts in the developing world to carry out their aggressions and extend their influence, resulted in indirect engagement among great power forces.21 Thus, although the last half century or so has not witnessed a major war in the proper sense, the great powers have engaged in indirect battles against one another. In the post-Cold War period, proxy wars are no longer a[n] well exercised avenue for great power aggressions, and, as indicated above, in recent years, even the United States and the Soviet Union have undergone notable reductions in the size of their armed forces and the amount of weaponry at their disposal. Yet, in spite of this, many great powers continue to prepare for and engage in war. What is noteworthy, however, is that the wars in which great powers are currently involved seem to fundamentally differ from those of the past. No longer do such wars seem to be primarily about expanding territory or influence, nor are they fought between great powers. Rather, these wars now seem to be generally motivated by humanitarian concerns, taking the form of collective operations sanctioned by multilateral institutions that aim to ensure the stability of developing countries wrought by violence.22 The North Atlantic Treaty Organization’s (NATO) efforts in Kosovo in 1999 and, more recently, in Afghanistan would seem indicative of such forms of intervention, with many great powers working together to protect human rights and promote human security worldwide. To be sure, such protection is more necessary now than ever before as less conventional forms of violence, such as terrorism, have begun to flourish.23 Ultimately, although the great powers are still engaged in war, such aggressions are no longer targeted at one another, nor do they appear to be aggressions in the proper sense. It would seem that their engagement in battle has undergone an evolution away from major war to humanitarian interventions, an evolution that can be tied to the shifting perceptions of war among populations in the developed world. Indeed, beyond analyses as to the frequency of major war, further support for the obsolescence of this institution can be found in a shift towards a non-militaristic political psychology.24 Evidenced not only by the reductions in military preparedness worldwide, but also by cultural and political trends, this shift would seem to be cementing in the developed world, particularly among the great powers whose behaviour is our primary concern. In the past, war has been glorified as a heroic and virtuous endeavour, an inevitable product of human nature that cannot be overcome.25 However, after centuries of violent warfare on the European and Asian continents, beginning as early as the seventeenth century, these views surrounding war began to change throughout the developed world.26 The first truly active and persistent group that sought to reform sentiments surrounding war appears to have been the Quakers, a religious group that formed in England in 1652 and It was not until the end of the Napoleonic Wars of 1803-1815 that anti-war sentiments truly began to flourish, with the Quakers and others establishing the first anti-war societies in Europe and North America.28 With many minority groups opposing or prophesising the conclusion of war, including such note-worthy scholars as Immanuel Kant and John Stuart Mill, anti-war sentiment grew in the years leading up to the First World War, resulting in governments of major countries having to justify war in a way that had not been needed in the past.29 In some states, including Spain, Sweden, Switzerland, Denmark, Portugal, and the Netherlands, anti-war sentiment became so pronounced that governments sought to reform their foreign policy and avoid war altogether.30 However, it was not until the cataclysm of World War I that anti-war sentiments moved to the forefront in great power societies.31 Novels and memoirs of the 1920s expressed espoused a strong reverence for life.27 Though vocal, their initial impact was limited. these views profoundly and pushed them into even wider circulation.32 Such sentiments were also present in international politics as almost all of the great powers of the time pursued a policy of war aversion. Arguably, World War II would not have broken out if it were not for the charismatic Hitler or the aggressive policies of the Japanese.33 The consequence of World War I was that most major countries had foresworn war, at least major war. World War II simply reaffirmed these sentiments. The growing disdain for war continued throughout the Cold War period and appears to have cemented today among the great powers. In the United States, the world’s current superpower, antiwar sentiment became particularly pronounced during the Vietnam War, and negative sentiments can be seen today surrounding the Iraq War in both the United States and the United Kingdom.34 None of these were wars were major wars, but the message remains the same, namely that citizens in these countries are wary of devoting resources and lives to the pursuit of war. Indeed, as indicated above, most of the great powers have reduced the amount of resources devoted to developing strong militaries and are generally on peaceful terms with one another. Countries like Germany and France, which, for centuries, have devoted significant amounts of time and resources to directly fighting one another or planning to do so, are now engaged in peaceful relations. Even Japan, a striking former aggressor state, seems to have embraced peace. Ultimately, it would seem that the current absence of major war is not simply a temporary lull, but a more lasting change that has been developing for centuries. Major war is not simply absent, it is obsolescent. A wide range of causes come together to account for such obsolescence, which we will now examine in greater detail. 2. No miscalculation – and deterrence, globalization, and democratic peace check conflict. Aziz 14 (John: analyst of economics, finance, geopolitics and history, “Don't worry: World War III will almost certainly never happen,” The Week, March 06, 2014, http://theweek.com/articles/449783/dont-worry-world-war-iii-almost-certainly-never-happen, accessed July 13, 2016) DDI-BL Next year will be the seventieth anniversary of the end of the last global conflict. There have been points on that timeline — such as the Cuban missile crisis in 1962, and a Soviet computer malfunction in 1983 thaterroneously suggested that the U.S. had attacked, and perhaps even the Kosovo War in 1999 — when a global conflict was a real possibility. Yet today — in the shadow of a flare up which some are calling a new Cold War between Russia and the U.S. — I believe the threat of World War III has almost faded into nothingness. That is, the probability of a world war is the lowest it has been in decades, and perhaps the lowest it has ever been since the dawn of modernity. This is certainly a view that current data supports. Steven Pinker's studies into the decline of violence reveal that deaths from war have fallen and fallen since World War II. But we should not just assume that the past is an accurate guide to the future. Instead, we must look at the factors which have led to the reduction in war and try to conclude whether the decrease in war is sustainable. So what's changed? Well, the first big change after the last world war was the arrival of mutually assured destruction. It's no coincidence that the end of the last global war coincided with the invention of atomic weapons. The possibility of complete annihilation provided a huge disincentive to launching and expanding total wars. Instead, the great powers now fight proxy wars like Vietnam and Afghanistan (the 1980 version, that is), rather than letting their rivalries expand into fullon, globe-spanning struggles against each other. Sure, accidents could happen, but the possibility is incredibly remote. More importantly, nobody in power wants to be the cause of Armageddon. But what about a non-nuclear global war? Other changes — economic and social in nature — have made that highly unlikely too. The world has become much more economically interconnected since the last global war. Economic cooperation treaties and free trade agreements have intertwined the economies of countries around the world. This has meant there has been a huge rise in the volume of global trade since World War II, and especially since the 1980s. Today consumer goods like smartphones, laptops, cars, jewelery, food, cosmetics, and medicine are produced on a global level, with supply-chains criss-crossing the planet. An example: The laptop I am typing this on is the cumulative culmination of thousands of hours of work, as well as resources and manufacturing processes across the globe. It incorporates metals like tellurium, indium, cobalt, gallium, and manganese mined in Africa. Neodymium mined in China. Plastics forged out of oil, perhaps from Saudi Arabia, or Russia, or Venezuela. Aluminum from bauxite, perhaps mined in Brazil. Iron, perhaps mined in Australia. These raw materials are turned into components — memory manufactured in Korea, semiconductors forged in Germany, glass made in the United States. And it takes gallons and gallons of oil to ship all the resources and components back and forth around the world, until they are finally assembled in China, and shipped once again around the world to the consumer. In a global war, global trade becomes a nightmare. Shipping becomes more expensive due to higher insurance costs, and riskier because it's subject to seizures, blockades, ship sinkings. Many goods, intermediate components or resources — including energy supplies like coal and oil, components for military hardware, etc, may become temporarily unavailable in certain areas. Sometimes — such as occurred in the Siege of Leningrad during World War II — the supply of food can be cut off. This is why countries hold strategic reserves of things like helium, pork, rare earth metals and oil, coal, and gas. These kinds of breakdowns were troublesome enough in the economic landscape of the early and mid-20th century, when the last global wars occurred. But in today's ultra-globalized and ultra-specialized economy? The level of economic adaptation — even for large countries like Russia and the United States with lots of land and natural resources — required to adapt to a world war would be crushing, and huge numbers of business and livelihoods would be wiped out. In other words, global trade interdependency has become, to borrow a phrase from finance, too big to fail. It is easy to complain about the reality of big business influencing or controlling politicians. But big business has just about the most to lose from breakdowns in global trade. A practical example: If Russian oligarchs make their money from selling gas and natural resources to Western Europe, and send their children to schools in Britain and Germany, and lend and borrow money from the West's financial centers, are they going to be willing to tolerate Vladimir Putin starting a regional war in Eastern Europe (let alone a world war)? Would the Chinese financial industry be happy to see their multi-trillion dollar investments in dollars and U.S. treasury debt go up in smoke? Of course, world wars have been waged despite international business interests, but the world today is far more globalized than ever before and well-connected domestic interests are more dependent on access to global markets, components and resources, or the repayment of foreign debts. These are huge disincentives to global war. But what of the militaryindustrial complex? While other businesses might be hurt due to a breakdown in trade, surely military contractors and weapons manufacturers are happy with war? Not necessarily. As the last seventy years illustrates, it is perfectly possible for weapons contractors to enjoy the profits from huge military spending without a global war. And the uncertainty of a breakdown in global trade could hurt weapons contractors just as much as other industries in terms of losing access to global markets. That means weapons manufacturers may be just as uneasy about the prospects for large-scale war as other businesses. Other changes have been social in nature. Obviously,democratic countries do not tend to go to war with each other, and the spread of liberal democracy is correlated against the decrease in war around the world. But the spread of internet technology and social media has brought the world much closer together, too. As late as the last world war, populations were separated from each other by physical distance, by language barriers, and by lack of mass communication tools. This means that it was easy for war-mongering politicians to sell a population on the idea that the enemy is evil. It's hard to empathize with people who you only see in slanted government propaganda reels. Today, people from enemy countries can come together in cyberspace and find out that the "enemy" is not so different, as occurred in the Iran-Israel solidarity movement of 2012. More importantly, violent incidents and deaths can be broadcast to the world much more easily. Public shock and disgust at the brutal reality of war broadcast over YouTube and Facebook makes it much more difficult for governments to carry out large scale military aggressions. For example, the Kremlin's own pollster today released a survey showing that 73 percent of Russians disapprove of Putin's handling of the Ukraine crisis, with only 15 percent of the nation supporting a response to the overthrow of the government in Kiev. There are, of course, a few countries like North Korea that deny their citizens access to information that might contradict the government's propaganda line. And sometimes countries ignore mass anti-war protests — as occurred prior to the Iraq invasion of 2003 — but generally a more connected, open, empathetic and democratic world has made it much harder for war-mongers to go to war. The greatest trend, though, may be that the world as a whole is getting richer. Fundamentally, wars arise out of one group of people deciding that they want whatever another group has — land, tools, resources, money, friends, sexual partners, empire, prestige — and deciding to take it by force. Or they arise as a result of grudges or hatreds from previous wars of the first kind. We don't quite live in a superabundant world yet, but the long march of human ingenuity is making basic human wants like clothing, water, food, shelter, warmth, entertainment, recreation, and medicine more ubiquitous throughout the world. This means that countries are less desperate to go to war to seize other people's stuff. But the tendency toward inertia is strong. It is clear at least that the incentives for world war are far lower than they were in previous decades, and the disincentives are growing. The apocalyptic visions of a new world war between nations or empires that three generations of children have been raised into continue to diminish. 3. Nuclear war doesn’t cause extinction – their evidence is propaganda. Wigner 04 (Eugene P. Wigner. Physicist, Nobel Laureate, and the only surviving initiator of the Nuclear Age; Nuclear War Survival Skills; “Ch. 1: The Dangers from Nuclear Weapons: Myths and Facts”; 2004; http://www.oism.org/nwss/s73p912.htm; DT) ° Facts: Unsurvivable "nuclear winter" is a discredited theory that, since its conception in 1982, has been used to frighten additional millions into believing that trying to survive a nuclear war is a waste of effort and resources, and that only by ridding the world of almost all nuclear weapons do we have a chance of surviving. Non-propagandizing scientists recently have calculated that the climatic and other environmental effects of even an all-out nuclear war would be much less severe than the catastrophic effects repeatedly publicized by popular astronomer Carl Sagan and his fellow activist scientists, and by all the involved Soviet scientists. Conclusions reached from these recent, realistic calculations are summarized in an article, "Nuclear Winter Reappraised", featured in the 1986 summer issue of Foreign Affairs, the prestigious quarterly of the Council on Foreign Relations. The authors, Starley L. Thompson and Stephen H. Schneider, are atmospheric scientists with the National Center for Atmospheric Research. " that on scientific grounds the global apocalyptic conclusions of the initial nuclear winter hypothesis can now be relegated to a vanishing low level of probability." Their models indicate that in July (when the greatest temperature reductions would result) the average temperature in the United States would be reduced for a few days from about 70 degrees Fahrenheit to approximately 50 degrees. (In contrast, under the same conditions Carl Sagan, his associates, and the Russian They showed scientists predicted a resulting average temperature of about 10 degrees below zero Fahrenheit, lasting for many weeks!) Persons who want to learn more about possible post-attack climatic effects also should read the Fall 1986 issue of Foreign Affairs. This issue contains a long letter from Thompson and Schneider which further demolishes the theory of catastrophic "nuclear winter " Continuing studies indicate there will be even smaller reductions in temperature than those calculated by Thompson and Schneider. Soviet propagandists promptly exploited belief in unsurvivable "nuclear winter to increase fear of nuclear weapons and war, and to demoralize their enemies. Prioritize inevitable extinction scenarios – reducing warming by just a billionth of a billionth of a percent is worth a hundred billion times as much as saving a billion lives. Bostrom 13 (Nick: a Swedish philosopher at the University of Oxford known for his work on existential risk, the anthropic principle, human enhancement ethics, superintelligence risks, the reversal test, and consequentialism; “Existential Risk Prevention as Global Priority”; Global Policy Volume 4 . Issue 1 . February 2013; http://www.existential-risk.org/concept.pdf; DT) But even this reflection fails to bring out the seriousness of existential risk. What makes existential catastrophes especially bad is not that they would show up robustly on a plot like the one in Figure 3, causing a precipitous drop in world population or average quality of life. Instead, their significance lies primarily in the fact that they would destroy the future. The philosopher Derek Parfit made a similar point with the following thought experiment: I believe that if we destroy mankind, as we now can, this outcome will be much worse than most people think. Compare three outcomes: 1. Peace. 2. A nuclear war that kills 99 per cent of the world’s existing population. 3. A nuclear war that kills 100 per cent. 2 would be worse than 1, and 3 would be worse than 2. Which is the greater of these two differences? Most people believe that the greater difference is between 1 and 2. I believe that the difference between 2 and 3 is very much greater. The Earth will remain habitable for at least another billion years. Civilisation began only a few thousand years ago. If we do not destroy mankind, these few thousand years may be only a tiny fraction of the whole of civilised human history. The difference between 2 and 3 may thus be the difference between this tiny fraction and all of the rest of this history. If we compare this possible history to a day, what has occurred so far is only a fraction of a second (Parfit, 1984, pp. 453–454). To calculate the loss associated with an existential catastrophe, we must consider how much value would come to exist in its absence. It turns out that the ultimate potential for Earth-originating intelligent life is literally astronomical. One gets a large number even if one confines one’s consideration to the potential for biological human beings living on Earth. If we suppose with Parfit that our planet will remain habitable for at least another billion years, and we assume that at least one billion potential exist for at least 1016 human lives of normal duration. These lives could also be considerably better than the average contemporary human life, which is so often marred by disease, poverty, injustice, and various biological limitations that could be partly overcome through continuing technological and moral progress. However, the relevant figure is not how many people could live on Earth but how many descendants we could have in total. One lower bound of the number of biological human life-years in the future accessible universe (based on current cosmological estimates) is 1034 years.7 Another estimate, which assumes that future minds will be mainly people could live on it sustainably, then the implemented in computational hardware instead of biological neuronal wetware, produces a lower bound of 1054 human-brainemulation subjective life-years (or 1071 basic computational operations) (Bostrom, 2003).8 If we make the less conservative assumption that future civilisations could eventually press close to the absolute bounds of known physics (using some as yet unimagined technology), we get radically higher estimates of the amount of computation and memory storage that is achievable and thus of the number of years of subjective experience that could be realised.9 Even if we use the most conservative of these estimates, which entirely ignores the possibility of space colonisation and software minds, we find that the expected loss of an existential catastrophe is greater than the value of 1016 human lives. This implies that the expected value of reducing existential risk by a mere one millionth of one percentage point is at least a hundred times the value of a million human lives. The more technologically comprehensive estimate of 1054 humanbrain-emulation subjective life-years (or 1052 lives of ordinary length) makes the same point even more starkly. Even if we give this allegedly lower bound on the cumulative output potential of a technologically mature civilisation a mere 1 per cent chance of being correct, we find that the expected value of reducing existential risk by a mere one billionth of one billionth of one percentage point is worth a hundred billion times as much as a billion human lives. One might consequently argue that even the tiniest reduction of existential risk has an expected value greater than that of the definite provision of any ‘ordinary’ good, such as the direct benefit of saving 1 billion lives. And, further, that the absolute value of the indirect effect of saving 1 billion lives on the total cumulative amount of existential risk—positive or negative—is almost certainly larger than the positive value of the direct benefit of such an action.10
