  2. 2. Greenhouse Effect, Climate Change, Global Warming<br />Greenhouse Effect-Warming of the Earth’s surface as a result of atmospheric pollution by gases<br />Climate change-long term alteration in global weather patterns, especially a increase in temperature and storm activity. <br />Global Warming-an increase in the worlds temperature believed to be caused by greenhouse gases<br />
  3. 3. How are they related?<br />Climate change and global warming are both caused by greenhouse gases<br />Climate Change<br />Greenhouse gases<br />Global Warming<br />
  4. 4. What is Causing Global Warming?<br />The main cause for global warming is the excessive amount of carbon dioxide in the atmosphere<br />Other contributors include methane, nitrous oxide and deforestation<br />
  5. 5. Consequences if we don’t stop<br />Sea levels will rise <br />Hurricanes and other storms will be stronger<br />Species that depend on each other could go out of sync<br />Floods and droughts will be more common <br />Less freshwater will be available<br />Diseases will spread<br />Ecosystem will change some species will become extinct and others could be more successful <br />
  6. 6. How will global warming effect the economy?<br />High CO2<br /> Cause plants like corn and beans to grow very big causing farmers to have a abnormal growing season. <br />This cause the need for more food all around the world. <br />Prices will rise.<br />Insects have more to feed on, severe drought, and scarcity for water could happen due to all these plants. <br />
  7. 7. How can we fight global warming?<br />Buy cars that are efficient<br />Buy environment safe chemicals<br />Buy light bulbs that are CFLs or LED<br />Buy energy efficient light bulbs <br />
  8. 8. Basic arguments of Global warming<br />Some scientists do not believe human activities threaten to disrupt the Earths climate<br />Our most reliable sources of temperature how no global warming trend.<br />Is it a scam?<br />A modest amount of global warming, should it occur, would be beneficial to the natural world and to human civilians.<br />
  9. 9. Thoughts and Opinions<br />Though global warming is caused by natural effects as well as human effects, the human effects are causing thousands of years of damage to be done in a very short amount of time.<br />If we don’t change our energy system to a more eco-friendly one soon, the effects could be deadly.<br />
