Text shall be written for language skill of about Grade 6 level reading comprehension. Use short sentences and avoid words that represent complex concepts. Programming and Outreach opportunities. This experience could exist as an online portal, with nation-wide and in museum results being combined. Visitor experience: H1 Introduction to climate change. Located outside of the immersive glacier, this pod provides visitors with basic information that they need to understand climate change. H1 L1 Module Title: Climate Change H1 L1 Module Intro text Message: The way that we exploit natural resources to meet our needs and wants impacts our climate. Key quote (as wall writing): “Carbon dioxide is the most important anthropogenic greenhouse gas. […] The primary source of the increased atmospheric concentration of carbon dioxide since the pre-industrial period results from fossil fuel use.” Intergovernmental Panel on Climate Change H1-1 Climate change basics H1-1 L2 title: What is climate change? 30 April 2017 7:58 PM H1-1 L2 text (This is an exhibition team/corporation statement)- : We are using ‘climate change’ to specifically refer to anthropogenic climate change which is attributed to human activity - which is in addition to natural climate variability. H1-1 L3 title (under the above statement): Anthropogenic climate change H1-1 L3 text: The main cause of global warming since the industrial revolution is human activity. H1-1 graph: H1-1 graph caption: For the past 100,000 years, the Earth’s temperatures have naturally increased at a rate of 0.05 degrees Celsius per 100 years. Due to human induced climate change, temperatures observed over the past 50 years have already increased 0.7 degrees Celsius. (That’s at a rate of 1.4 degrees per 100 years!) Anthropogenic causes of climate changei: - Greenhouse gases including: o Carbon dioxide (CO2) – 90% of emissions o Methane o SF6 o Nitrous oxide - Conversion of land for forestry and agriculture (Beside Anthropogenic climate change under statement above) H1-1 L3 title: Natural changes H1-1 L3 text: The Earth's climate has changed throughout its history long before human activity could have played a role. For example, the planet has swung between cold glacial periods or "ice ages", and warm interglacial periods over the last few million years. Natural causes for change: - Output of the Sun - Changes in volcanic activity - Alterations of solar radiation reaching the Earth due to changes in the Earth’s orbit - Oceans phases - Naturally emitted greenhouse gases (e.g. water vapour) H1-1-2 title: Why do greenhouse gases cause the Earth to warm? (combination of the two graphics below) (50 words label, title, caption) 30 April 2017 7:58 PM H1-1-2 Graphic: H1-1-2 Graphic caption: See text in graphic below. http://thehigherlearning.com/2014/10/13/nasa-confirms-that-huge-methane-cloud-in-u-ssouthwest-is-real-deal/ http://climate.nasa.gov/system/content_pages/main_images/1_normPage-3.jpg L3 title: Climate change and global warming – what’s the difference? L3 text: Both terms refer to anthropogenic warming of the planet, but climate change is more than just temperature. Global warming is the long-term trend of rising average global temperature. Climate change includes all of the changes in the global climate such as changes in precipitation, wind, snowfall etc., which are a result of the increasing global temperature. H1-1-2 Graphic2 30 April 2017 7:58 PM H1-1-2 Graphic2 title: How much is the temperature increasing? H1-1-2 Graphic caption: Based on evidence collected since 1880, climate researchers have shown that the Earth’s average temperature has increased. Two-thirds of the warming has occurred since 1975, at a rate of roughly 0.15-0.20 degrees Celsius per decade. H1-1-3 L2 title: Why is there an increase of greenhouse gases in the atmosphere? (50 words) H1-1-3 L2 text: Greenhouse gases – especially CO2 - are the main contributors to global warming. We all make choices which add carbon to the atmosphere, or slows its removal. In addition to our personal transportation and food choices, industries which transform natural resources to produce the goods and services we need and want also impact CO2 levels. H1-1-3 L3 text: Individual contributions to CO2 levels (on left under L2 text) (30 words- could be done with little graphics (little car, steak, etc) Transportation choices – burning of fossil fuels. Food choices – producing meat increases CO2 emissions. Heating / cooling house – burning fossil fuels and produce electricity to heat \cool Our high demand for of appliances, electronics and lighting – use of natural resources, and energy to manufacture increases CO2 emissions High turn-over of goods. H1-1-3 L3 text: What industries contribute CO2 emissions? (on right under L2 text) H1-1-3 Graph title: CO2 emissions by industry sector (Can we can relabel show the % (not the absolute Mt of CO2), and can we change the labels to be more intuitive – or have information in caption). See backgrounder for more information. (40 words labels + caption) 30 April 2017 7:58 PM H1-2 Graph caption: Industrial CO2 emissions. Each economic sector includes emissions from energy-related and non-energy related processes. Source: Environment Canada H1-1-4 Graphic or 3D bathtub - Earth’s carbon balance (bathtub or other): natural and anthropogenic. How is carbon imbalance warming the planet? Perhaps we need to reinforce this point (https://climateinteractive.files.wordpress.com/2009/11/ngbathtub.jpg) 100 words total including labels and caption. H1-1-4: The Earth is naturally able to uptake carbon from the atmosphere. Carbon is required for life, and the carbon cycle provides a balance on Earth. When the amount of carbon entering the atmosphere exceeds the amount being removed, we have a carbon imbalance, which is contributing to the warming of the planet.

History of climate change. (We are suggesting this as a combination of a timeline, with graphs on same time scale. Perhaps this would be a counter panel which runs along the bottom of the text of H1, H3, potentially culminating in a large thermometer?). H1-2 L2 title: Climate change from 1775 to today. H1-2 Graph #1: Human population (indirect contributor to climate change) See graph at bottom of world population counter: http://www.worldometers.info/world-population/ (Significant milestones - potentially highlighted on graph): 1800 – World population reaches one billion. 1930 – Human population reaches two billion. 1960 – Human population reaches three billion. 1975 – Human population reaches four billion. 1987 – Human population reaches five billion. 1999 – Human population reaches six billion. 2011 – Human population reaches seven billion.

H1-2 Graph #3: Global temperature http://climate.nasa.gov/vital-signs/global-temperature/ (Potential Significant milestones to indicate on graph): 1990 – Warmest year on record due to strong El Nino and global warming. (To soon be beaten) 2015 – Mean global temperature is 14.7C, the warmest in thousands of years. Level of CO2 in the atmosphere reaches 400 ppm, the highest in millions of years. (NASA and NOAA) 2000-2016 – 15 of the first 16 years of this millennia have been the warmest on record. H1-2 TIMELINE CONTENT (to be depicted as a fourth line, running parallel to the three graphs above) (10 words per date) Late 1700s to first half of 1800s – The industrial revolution: the mechanization of production, high increase in use of coal (railways, factories and heating), iron and chemicals. 30 April 2017 7:58 PM 1824 – Physicist Joseph Fourier describes the Earth’s natural “greenhouse effect”. 1861 – Physicist John Tyndall shows that water vapour and certain gases create the greenhouse effect. 1886 – Karl Benz unveils the Motorwagen, regarded as the first internal combustion automobile. 1896 – Chemist Svante Arrhenius uses the concept of “man-made greenhouse” while concluding that industrial-age coal burning will enhance the natural greenhouse effect. 1908 – Henry Ford develops the first automobile that can be mass manufactured and used by many middle class citizens. 1938 – Using records from 147 weather stations around the world, British engineer Guy Callendar shows that temperatures had risen over the previous century. He also highlights that CO2 concentrations had increased over that same period, suggesting that this caused the warming. 1957 – Roger Revelle and chemist Hans Suess demonstrate that seawater is not able to absorb all of the additional CO2 entering the atmosphere. “Human beings are now carrying out a large scale geophysical experiment…” 1958 – Charles David Keeling designs systematic measurements of atmospheric CO2 at Mauna Loa in Hawaii and in Antarctica. Within four years, the project – which continues today – provides the first unequivocal proof that CO2 concentrations are rising. 1965 – A US President’s Advisory Committee panel warns that the greenhouse effect is a matter of “real concern”. 1972 – First UN environment conference. Climate change is hardly mentioned. 1975 – US scientist Wallace Broecker puts the term “global warming” into public domain in the title of a scientific paper. 1987 – Montreal Protocol signed. This protocol international treaty restricted the use of chemicals that damage the ozone layer. Although not the goal at the time, looking back, this treaty has had a major impact on greenhouse gas emissions, exceeding even the impacts of the later Kyoto Protocol. 1990 – IPCC produces First Assessment Report. Conclusions: temperatures have risen by 0.30.6C over the last century; humanity’s emissions are adding to the atmosphere’s natural complement of greenhouse gases which is expected to result in warming. 1992 –Earth Summit in Rio de Janeiro. Governments agree to the United Framework Convention on Climate Change whose key objective is to stabilize greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system. Developed countries agree to return their emissions to 1990 standards. 30 April 2017 7:58 PM 1995 – The first definitive statement that humans are responsible for climate change. The IPCC Second Assessment Report concludes that the balance of evidence suggests “a discernible human influence” on the Earth’s climate. 1997 – Kyoto Protocol signed. Developed nations pledge to reduce emissions by an average of 5% by the period 2008-12, with wide variations on targets for individual countries. US Senate immediately declares it will not ratify the treaty. 2003 – Numerous observations raise concern that collapse of ice sheets (West Antarctica, Greenland) can raise sea levels faster than most had believed. 2006 – The Stern Review concludes that climate change could cause severe economic damage – reducing gross domestic product (GDP) by up to 20% if left unchecked – but curbing it would cost about 1% of global GDP. 2007 – The IPCC and former US vice-president Al Gore receive the Nobel Peace Prize for spreading knowledge about climate change and for laying the foundations for the measures that are needed to counteract such change. 2011 – Canada withdraws from Kyoto Protocol 2013 – The first part of the IPCC’s fifth assessment report summarizes that humans are the dominant cause of global warming since the 1950s. 2015 – COP21 in Paris where 195 countries agreed to keep global warming to well below 2 degrees C. 2016 – COP22 in Marrakesh i World Meteorological Organization, “Causes of Climate Change”, wmo.int. https://www.wmo.int/pages/themes/climate/causes_of_climate_change.php IPCC Timeline https://www.ipcc.ch/news_and_events/docs/factsheets/FS_timeline.pdf
