1. Global Warming Meagan Calhoun and Storm Asbury Period 3

2. What is Greenhouse Effect? The result of greenhouse gasses trapping the Sun’s heat and keeping it close to the Earth, crucial and essential for life What is Climate Change? A shift in long term temperatures and weather patterns What is Global Warming? The increase of Earth’s average surface temperature due to effect of greenhouse gassestrapping heat

3. How are they all related?

4. What causes global warming? Humans Greenhouse gas emissions: Burning of fossil fuels in cars, factories, and electricity production Methane from landfills and agriculture Nitrous oxide from fertilizers *Carbon dioxide is most responsible* Deforestation takes away trees that absorb carbon dioxide

5. What are the possible consequences if we don’t take action? Health hazards: Asthma/breathing problems Heat waves Threat to wildlife Ecosystems out of balance Some plants will not be able to handle extreme temperatures Glaciers and sea levels rising

6. Impact on the economy: High energy prices due to global warming can eventually devastate our economy Businesses face a big financial risk if they refuse to adapt to the changing climate APA-American Power Act draft: Puts limits on releasing of greenhouse gasses Proposes new energy efficiency Could potentially reduce climate Groups made to support: EPA (Environmental Protection Agency) USGCRP(United States Global Change Research Program) IPCC(International Panel On Climate Change)

7. How can we fight globalwarming? Conserve energy: Choose fluorescent light bulbs over regular, will keep nearly 700 pounds of CO² out of our atmosphere Energy star rated appliances such as a refrigerator or washer will use at least 15% less energy than federal requirements Switch to hybrid or electric car, or ride your bike

8. Arguments against global warming: Scientists don’t believe human activities threaten Earth’s climate (IPCC didn’t prove) Reliable sources of temperature data show no global warming trend Computer models are just predictions Costly to make changes, threat to the budget

9. Opinions: Global warming is bad!! Global warming cannot be reversed, but we can make changes to keep it from getting any worse. We need to take action and make changes: Ride my bike Turn off lights not in use Unplug things I’m not using
