  2. Greenhouse Gases • Greenhouse Gases- Gases in the atmosphere that trap heat and reflect it back to Earth • Carbon Dioxide, Methane, Water Vapor, Nitrogen Oxide • Some Greenhouse gases occur naturally • Others are created solely through human activity • Without greenhouse gases, our planet would not be able to retain heat and would freeze

  3. Fossil Fuels • Fuels naturally made during the decomposition of dead organisms • Coal, Natural gas, oil • When burned, fossil fuels emit Carbon Dioxide

  4. What is Global Warming ? • Global warming • Warming of Earth’s surface temperature based on temperature records worldwide. • Occurs when greenhouse gases trap heat in Earth’s Atmosphere

  5. The planet will gradually heat up due to human contribution to greenhouse gases in the atmosphere

  6. Effects of Global Warming on Plants and Animals Icecaps melt Sea level rises More Natural Disasters/Killer Storms

  7. Direct Threats to Humans Higher risk of disease: - spread through insects More severe and higher amount of droughts and heat waves Crop Failure Damaged Economy Hurricane Damage costs, Disease control costs, Agricultural damage costs

  8. What is the Government Doing to Help? The government passes laws and regulations to limit the amount of greenhouse gases being released. Sponsoring research labs that are studying new sources of energy.

  9. The Clean Air Act • The Clean Air Act was amended in 1970 and in 1990 in the US • The act set requirements for what substances and how much of them could be released into the air

  10. What Can We Do to Help? • Carpool • Thermostat control: • - 2° down in winter and 2° up in the summer • Cover your pots when cooking • Purchase energy efficient products: • - Switching to fluorescent light bulbs will decrease 300 lbs. of carbon waste per year • Urge others to do the same thing!!

  11. Who Should We Call? • The World Resources Institute • The WRI provides practical strategies to help protect earth. • (202)343-9990 • Or Visit: http://www.wri.org/ • The US Environmental Protection Agency • The EPA enforces regulations and studies environmental issues such as global warming • (202)729-7600 • Or Visit: http://www.epa.gov/climatechange
