Jones English Teacher, Chengdu, Sichuan, China B.A., Northwestern University M.A., University of Missouri TESOL, Univ. of California, Los Angeles Fields of Study: Public Speaking, Writing, International Relations, Art HistoryPowerPoint Presentation: outline definitions issues pro / con an inconvenient truth practice debate conclusionPowerPoint Presentation: global warming noun an increase in the average temperature of the earth's atmosphere and oceans, especially a sustained increase sufficient to cause climatic change.PowerPoint Presentation: definitionsPowerPoint Presentation: Global Warming Greenhouse Gas The Greenhouse Effect Intergovernmental Panel on Climate Change (IPCC) Tradable Pollution Quotas Kyoto ProtocolPowerPoint Presentation: WHAT IS GLOBAL WARMING? Temperatures are rising because we have dramatically increased the amount of carbon dioxide in the Earth’s atmosphere, by burning fossil fuels such as coal, gas, and oil, and by clearing forests.PowerPoint Presentation: Greenhouse Gas : A gas which traps the sun's heat:PowerPoint Presentation: Greenhouse Gas : A gas which traps the sun's heat: Water vapor (H 2 O) Carbon dioxide (CO 2 ) - exhaust from cars and power plants. Methane (CH 4 ) - from decomposing organic matter.PowerPoint Presentation: Carbon dioxide and methane levels are at their highest levels in the past 420,000 years.The Greenhouse Effect: The Greenhouse EffectPowerPoint Presentation: Intergovernmental Panel on Climate Change (IPCC) A scientific body formed in 1988 to evaluate the risk of climate change caused by human activity.PowerPoint Presentation: Tradable Pollution Quotas A country that wants to exceed its quota of greenhouse emissions can buy part of another country’s quota of polluting gases.PowerPoint Presentation: Kyoto Protocol A 1997 international treaty designed to limit global greenhouse gas emissions during the years 2008 - 2012. Goal: to reduce greenhouse-gas emissions 5% below 1990 levels.PowerPoint Presentation: Kyoto Protocol The United States and Australia have not ratified the Kyoto Protocol. The U.S. is responsible for about a quarter of the emissions that have been blamed for global warming.PowerPoint Presentation: issuesPowerPoint Presentation: Who is responsible?PowerPoint Presentation: Most scientists blame industrialization: Automotive Industry (low fuel economy) Oil companies (fossil fuels)PowerPoint Presentation: Power plants (coal) Agri-business (biofuels, deforestation, cattle producing methane) Logging Industry (deforestation)PowerPoint Presentation: Consequences of global warmingPowerPoint Presentation: Catastrophic weather such as hurricanes will increase.PowerPoint Presentation: Melting polar icecaps will raise ocean levels; the Arctic Ocean could be ice free in summer by 2050.Heat waves, droughts, and wildfires will be more frequent. : Heat waves, droughts, and wildfires will be more frequent.PowerPoint Presentation: Up to 300,000 people a year will die – partly from the spread of tropical diseases.PowerPoint Presentation: More than a million species worldwide could be extinct by 2050.PowerPoint Presentation: EndangeredPowerPoint Presentation: Global sea levels could rise by more than 20 feet, devastating coastal areas worldwide.PowerPoint Presentation: The future of our coastal cities?PowerPoint Presentation: Between 1970 and 2004 global greenhouse gas emissions have increased by 70 %PowerPoint Presentation: SOME FACTS:PowerPoint Presentation: From 1971 to 2005 CO2 vehicle emissions rose from 1.8 billion tons per year to 4.6 billion tons per year. The average global air temperature rose between 0.5 and 0.74 degrees C during the past century. An average 2 degrees C warming is predicted by 2100. Sea level has risen between 10 to 25 cm in the last 100 years.PowerPoint Presentation: The Earth is getting warmer. What causes the warming is hotly debated.The Argument:: The Argument: Human causes ( Anthropogenic ): Carbon dioxide (CO 2 ) exhaust from cars and power plants. Methane gas from waste DeforestationThe Argument:: The Argument: Natural causes: Some claim the sun is getting hotter. Also, the earth goes through natural cycles of climate change.Evidence that CO2 is Cause: Evidence that CO 2 is Cause carbon dioxide vs. global temperature graphIs Global Warming for Real?: Is Global Warming for Real?1973 CONFLICTING INFORMATION 2005: 1973 CONFLICTING INFORMATION 2005PowerPoint Presentation: Is it already too late?PowerPoint Presentation: an inconvenient truthPowerPoint Presentation: Al Gore 2007 Nobel Peace Prize Former Vice President of the United StatesPowerPoint Presentation: pro / conPowerPoint Presentation: The big debate is political:PowerPoint Presentation: Global warming's harmful potential has been proved; now we must prevent it from getting worse. OR The evidence is inconclusive; trying to prevent global warming could destroy the economy.PowerPoint Presentation: Who is responsible for slowing global warming, and at what cost?Industrialization is the primary cause of global warming.: Industrialization is the primary cause of global warming.Are alternative sources of energy the answer? : Are alternative sources of energy the answer?The Kyoto Protocol – effective or not? : The Kyoto Protocol – effective or not? Industries should cut greenhouse gas emissions now.: Industries should cut greenhouse gas emissions now. What are the costs of slowing global warming?: What are the costs of slowing global warming?PowerPoint Presentation: Can you have economic growth and protect the earth at the same time?Emissions quota trading: Emissions quota trading Will it work? Is unlimited economic growth really desirable?: Is unlimited economic growth really desirable?PowerPoint Presentation: practice debateTopic 1:: Industrial growth should be slowed or limited in order to curb global warming. Topic 1:Topic 2:: Topic 2: Do newly-developed economies, like India and China, have a right to increase their industrial emissions?Something to think about:: Something to think about:PowerPoint Presentation: Climate change may just be too big and too vague a problem for people to want to invest in trying to solve. People like to fund things they know will work.PowerPoint Presentation: It will be the political process and fear of the unknown that will generate the needed response by developed countries to mitigate carbon emissions worldwide, if this response is generated at all.Thank you: Thank you You do not have the permission to view this presentation.
