Global warming ppt

  1. 1. Global Warming<br />Meagan Calhoun and Storm Asbury<br />Period 3<br />
  2. 2. What is Greenhouse Effect?<br />The result of greenhouse gasses trapping the Sun’s heat and keeping it close to the Earth, crucial and essential for life<br />What is Climate Change?<br />A shift in long term temperatures and weather patterns<br />What is Global Warming?<br />The increase of Earth’s average surface temperature due to effect of greenhouse gassestrapping heat<br />
  3. 3. How are they all related?<br />
  4. 4. What causes global warming?<br />Humans<br />Greenhouse gas emissions:<br />Burning of fossil fuels in cars, factories, and electricity production<br />Methane from landfills and agriculture<br />Nitrous oxide from fertilizers<br />*Carbon dioxide is most responsible*<br />Deforestation takes away trees that absorb carbon dioxide <br />
  5. 5. What are the possible consequences if we don’t take action?<br />Health hazards:<br />Asthma/breathing problems<br />Heat waves<br />Threat to wildlife<br />Ecosystems out of balance<br />Some plants will not be able to handle extreme temperatures<br />Glaciers and sea levels rising<br />
  6. 6. Impact on the economy:<br />High energy prices due to global warming can eventually devastate our economy<br />Businesses face a big financial risk if they refuse to adapt to the changing climate<br />APA-American Power Act draft:<br />Puts limits on releasing of greenhouse gasses<br />Proposes new energy efficiency<br />Could potentially reduce climate<br />Groups made to support:<br />EPA (Environmental Protection Agency)<br />USGCRP(United States Global Change Research Program)<br />IPCC(International Panel On Climate Change)<br />
  7. 7. How can we fight globalwarming?<br />Conserve energy:<br />Choose fluorescent light bulbs over regular, will keep nearly 700 pounds of CO² out of our atmosphere<br />Energy star rated appliances such as a refrigerator or washer will use at least 15% less energy than federal requirements<br />Switch to hybrid or electric car, or ride your bike<br />
  8. 8. Arguments against global warming:<br />Scientists don’t believe human activities threaten Earth’s climate (IPCC didn’t prove)<br />Reliable sources of temperature data show no global warming trend<br />Computer models are just predictions<br />Costly to make changes, threat to the budget<br />
  9. 9. Opinions:<br />Global warming is bad!! <br />Global warming cannot be reversed, but we can make changes to keep it from getting any worse.<br />We need to take action and make changes:<br />Ride my bike<br />Turn off lights not in use<br />Unplug things I’m not using<br />
