  1. 1. Climate Changes<br />By: Leah Hillegas and Alexa Claycomb<br />
  2. 2. What is….<br />Greenhouse Effect<br />Process that keeps earth’s climate warm and habitable.<br />80-90% is made of water vapor.<br />Made of carbon dioxide, methane, and a few other gases.<br />Climate Changes<br />Change in seasons and weather for a long period of time.<br />Can play a role in shaping natural ecosystems.<br />Global Warming<br />The human part of greenhouse gases.<br />This is what humans are putting into the atmosphere that’s bad for the earth.<br />
  3. 3. How are They Related?<br />Increases temperature and climate.<br />They are all effecting our earth.<br />All increasing at alarming rates.<br />
  4. 4. Primary Causes…<br />Accelerates natural climate cycles with human created emissions.<br />Humans burn too many fossil fuels.<br />Use of methane, nitrogen oxide from farming, and other harmful gases.<br />Buildup of CO2 in our atmosphere.<br />
  5. 5. Possible Consequences…<br />Greenhouse gases can stay in the atmosphere for hundred of years.<br />Spread of diseases – as northern get warmer, disease carrying insects migrate north. Bring disease with them.<br />Temperature of oceans rises; increases chance of more frequent and stronger hurricanes.<br />
  6. 6. Impacting Economy…<br />Good:<br />Longer growing season<br />Polar icecaps melting- opening N.W. passage; cheaper shipping costs.<br />Bad:<br />Killing trees; no timber.<br />More allergy and more health care costs.<br />Shorter winters.<br />
  7. 7. Several ways to Fight Global Warming….<br />Help reduce demand for fossil fuels.<br />Reduce, reuse, and recycle.<br />Use less heat and air conditioning.<br />Drive Less.<br />Use less hot water.<br />Buy energy efficient products. <br />
  8. 8. Basic Arguments….<br />Most scientists don’t believe human activities are a part of disrupting earth’s climate.<br />The IPCC do not prove human activities cause global warming.<br />Efforts to quickly reduce human greenhouse gas emissions would be too costly and would not stop the earth’s climate from changing.<br />
  9. 9. Our Personal Opinions….<br />From everything we have learned; we believe global warming in a serious issue on earth.<br />We believe humans affect global warming.<br />Everyone should do things to stop global warming.<br />
