Climate Change, Peak oil and Biodiversity Loss: Why Scientists are Terrified and Economists Complacent Joshua Farley Community Development and Applied Economics Gund Institute for Ecological Economics Universit of Vermont Outline of Presentation ● ● ● ● ● Brief Overview of Triple Crisis Why are conventional economists complacent about the problems? Why are ecological economists terrified about the problems… …and reasonably complacent about the solutions? Leverage points for changing the system Brief Overview of the Triple Crisis ● ● ● Peak Oil Global Climate Change Natural resource depletion/biodiversity loss Energy and the Economy ● ● ● ● Laws of thermodynamics: It is impossible to do work without low entropy energy No work = no economic production 86% of global energy use is fossil fuels 95% of nitrogen in our bodies was fixed by Haber process using natural gas Is the Market the Driver of Economic Growth, or Is Energy? ● ● Wealth of nations: 1776 First effective steam engine: 1784 ● ● Used to pump water from coal mines One barrel of oil = 20,000 hrs human labor Our oil consumption increases our work capacity by 340 hrs per person per day Status of Oil Reserves: The Hubbert curve-discovery The Hubbert curve-production Peak Oil ● ● ● ● ● Declining EROI Once production can no longer increase with demand, prices will skyrocket If price of oil is rising faster than returns on alternative investments, incentive to keep oil in ground Substitution with coal, tar sands, oil shale could prove disastrous Can cause serious disruption of economic system Climate Change: History of Fluctuations Punctuated by Uniquely Stable Period Is Climate Change Happening and is it Human Caused? ● Scientific method and climate change ● Sample size of one Extremely complex system Uncertain facts High stakes Urgent decisions Values matter ‘It is virtually impossible for mortals outside the group that did the modeling to understand the detailed results’. Nordhaus, 2006 ● No definitive answer How Fast will it Happen? Feedback Loops ● ● ● Warmer tundra releases methane Ice pack reflects ~90% of heat back into space, open land and water absorbs ~90% Warmer oceans hold less CO2 ● ● BBC headlines “Oceans are 'soaking up less CO2‘” ~1/2 as much as in 1990s. Warmer soils release more CO2 Etc. etc. etc. Summary of potential problems • • • • • Crop failures Water shortages Biodiversity loss Extreme weather Sea level rise, etc. Natural Resource Depletion and Biodiversity Loss Extinction in the News ● ● ● ● “Species disappearing at an alarming rate, report says” “We are confronting an episode of species extinction greater than anything the world has experienced for the past 65 million years.” Peter Raven, Missouri Botanical Gardens “By 2048 all current fish, seafood species projected to collapse” Irreversible change Biodiversity Loss and Time Lags: Case Study of Brazil’s Atlantic Forest Highest Biodiversity Terrestrial Ecosystem Known; 93% gone Rule of thumb from Island Biogeography: Loss of 90% of Ecosystem eventually leads to 50% loss of biodiversity Without immediate action to restore ecosystem, biodiversity may collapse; irreversible and catastrophic change Time Lags 2: Cassowaries Ecological Thresholds: Case Study Amazon ● ● ● Amazon recycles 50% of its rainfall Loss of 30% of forest may lead to irreversible, catastrophic change Recent estimates in neighborhood of > 20% loss • Including selective logging increased previous estimates of deforestation by 60% 2005 Record Drought The Resilience Question R T S y s t e m S ta te M S A T i m R e s i li e n c e = e M S / R T lt e r n a t iv e s t a t e Why Are Economists Complacent? History ● ● ● ● ● ● Malthus Jevons: “The Coal Question” Meadows et al. “The Limits to Growth” Ehrlich vs. Simon Environmental Kuznets Curve Endless growth and a richer future Theory ● Substitutability: ● P=f(K,L) ● Scarcity price increase innovation (substitutes) “The Ultimate Resource” Invisible hand will solve our problems Raw materials do not enter the production function, nor do waste emissions P=f(K,L,N) When raw materials do enter the production function, labor and capital function as substitutes Growth ● ● ● ● The larger our economy, the more we have to spend on environmental problems The wealthier people are, the more they care about the environment The wealthier people are, the fewer babies they have Economic growth is the solution to poverty, environmental problems and overpopulation Discounting ● Less value given to future than present ● ● Opportunity cost Pure time preference Distant future assigned negligible value Assumes endless growth The Truly Rosy View ● Schelling (Nobel Prize in 2005): “Agriculture and Forestry are less than 3% of total output, and little else is much affected. Even if agricultural productivity declined by a third over the next half century, the per capita GNP we might have achieved by 2050 we would still achieve in 2051.” ● Nordhaus, Beckerman and others parrot this view The Pessimistic View: The Stern Review ● ● ● ● Many models show loss of 0-3% of GDP for 2-3 C increase 5-10% of GDP for 5-6 C increase in comparison to what otherwise would have occurred. Stern suggests 5-20% loss of GNP over what otherwise would have occurred Baseline is economic growth of 2.3% per capita per year. Why sacrifice for a wealthier future? Why Ecological Economists Terrified about the Problems… What is Economics? ● ● The allocation of scarce resources among alternative desirable ends Before we can decide how to allocate, we must understand the physical characteristics of the scarce resources The Nature of the Scarce Resource: The Laws of Physics ● You can't make something from nothing ● All economic production requires the transformation of resources provided by nature Energy is required to do work All economic production requires energy Fossil fuels drive our economy The Laws of Physics ● You can't make nothing from something, and you can't burn the same match twice Everything the economy uses eventually returns to the ecosystem as waste © Basel Action Network The Laws of Ecology ● ● The raw materials converted into economic products are elements of ecosystem structure Ecosystem services are provided by a special configuration of ecosystem structure The Laws of Ecology ● ● ● ● If we deplete ecosystem structure, we deplete ecosystem services When we return waste to the ecosystem, we deplete ecosystem services. All economic activity affects ecosystem services Humans like all species depend on ecosystem services for their survival • The nature of the scarce resources has changed • If we want more timber, we need more forest, not more sawmills • Ecosystem services have grown relatively scarcer, and do not fit into the market model The Laws of Economics ● Stop engaging in an activity when rising marginal costs exceed diminishing marginal benefits Ecosystem Goods: Raw Materials ● ● ● Required for all economic production We can use them up as fast as we like If I use it, you can't ● ● ● Competition for use Can generally be owned Market goods Ecosystem structure, building blocks of ecosystems Do Prices Reflect Scarcity of Raw Materials? Neoclassical Economics Ignores Raw Material Inputs and Waste Outputs X = … or considers inputs substitutable with labor and capital X X X = X = Ecosystem Services ● ● ● ● Essential to human survival Include the capacity to regenerate structure Provided at a given rate over time If I use it, you still can (except waste absorption) ● ● ● Cooperative in use Can't be owned Non-market goods—no price signal to indicate scarcity Markets ignore ES The Laws of Ecology • • The raw materials converted into economic products are elements of ecosystem structure Ecosystem services are provided by a special configuration of ecosystem structure Ecosystem Services, uncertainty and Ignorance ● We often don't know what services are until they're gone Sardines and global climate change Passenger pigeons The ozone layer Impacts of Growth Ecological footprint Rising marginal costs The Role of Information ● ● ● Can help solve many of our problems if used correctly Information improves through use Do profits allocate resources to produce most important information? ● Do patents slow advance in knowledge? ● Eflornithine Nobel prize, anti-commons Patents allow price rationing, create artificial scarcity Ozone depletion Triple Crisis Caused by Catastrophic Failure of Existing Economic System ● ● ● ● ● Phenomenally successful at producing certain commodities for certain people, but ignores others Ecosystem services systematically ignored Triple crisis caused by economic decisions, emphasis on endless growth “We may be lost, but we’re making great time” Yogi Berra Fundamental transformation required Why Ecological Economists are more Complacent about Solutions ● ● Economics is the allocation of scarce resources among alternative desirable ends First question an economist must ask is what are the desirable ends? What are the Desirable Ends? ● A high quality of life for this and future generations ● Sustainability, Justice, Health, education, happiness, satisfaction with life as a whole Conventional economists claim unlimited wants Desirable end is ever increasing material consumption Economic growth is the solution Are we insatiable? • The Hunter-Gatherer economy – 99% of human history – Accumulation = death Diminishing marginal benefits of growth Per Capita GDP in Trinidad: ~ $9,500 Conventional Economics: Microallocation ● ● ● How do we convert raw materials and energy provided by nature into highest value end products? Decisions based on one dollar, one vote No when-to-stop rule: how much natural capital should we convert? Sustainable Economics: Macro-Allocation ● ● ● How much ecosystem structure must be left intact to provide life support functions and other services, and how much can be converted to (or degraded by) economic production? Markets unable to make this decision Democratic and cooperative methods better than plutocratic and competitive ones Just Economics: Reclaiming the Commons ● ● ● If resources are finite, then distribution matters Common property rights to resources created by nature or society as a whole Community decisions over macroallocation: oil use, waste emissions, resource depletion, airwaves, etc. Internalizes externalities Scale: how much to use? Distribution: who is entitled to use it? Would Addressing the Triple Crisis be a Sacrifice? ● ● ● ● ● Over 80% reduction in fossil fuel use required Per capita income (adjusted for inflation) in 1969 was 1/3 of today’s GDP Poverty was lower (evidence we can’t grow our way out of poverty) Energy intensity of GDP in 1969 was 2x today’s intensity We could live at 1969 standard with 17% of current CO2 emissions With proper incentives in place, we could do even better How Miserable was Life in 1969?: The Genuine Progress Indicator How do We Get There? ● Changing the paradigm ● Economy is sustained and contained by the global ecosystem Continuous economic growth is impossible Macroallocation is central problem Changing the goals Shared vision of a sustainable and desirable future. Continuous economic growth is undesirable Doom and gloom doesn’t win converts How do We Get There? ● Changing the rules ● Democratic control over the commons and the problem of macroallocation Cooperative provision/management of non-rival resources Just distribution of resources provided by nature and society Information flows Information improves through use Prices ration use, create artificial scarcity Transparent government Independent media How do We Get There? ● ● Must take advantage of windows of opportunity Creating commons sector alongside public sector and private sector Conclusions ● In a no-growth economy “There would be as much scope as ever for all kinds of mental culture, and moral and social progress; as much room for improving the Art of Living, and much more likelihood of its being improved, when minds ceased to be engrossed by the art of getting on.” John Stuart Mill, Of the Stationary State
