1. Global Warming Maggie Dammer Seth Susavage

3. Primary Causes Greenhouse gases like carbon dioxide and methane Burning of fossil fuels, industrial farming, and deforestation Water vapors can also cause global warming.

4. Possible Consequences Increasing sea levels Change in weather patterns and precipitation More tropical storms and hurricanes Malaria Flooding Poor air quality Heat stroke Extinction of some species

5. Economy Many countries are against climate change treaties due to what effect it will have on their economies Resource-dependent countries are most likely to be affected by climate change Costs of climate change are likely to be small Consequences are uncertain

6. Solutions If we stop emitting greenhouse gases, the Earth will still heat up about 1 degree Fahrenheit There is potential to capture CO2 from fossil fuels and hide it underground (carbon sequestration) Planting trees and plants will absorb excess CO2 naturally

7. Arguments against global warming More than 17000 scientists signed a petition saying that humans are not responsible for global warming Satellites in the lower troposphere have recorded no temperature change in 23 years Global warming predictions are based on computer models, not history The IPCC has yet to prove humans are the cause of global warming Global warming could be helpful to the world, like it was in the Medieval Warm Period

8. Opinions Global warming is a very real factor in our life that most scientists agree. But there are some other scientists that try to prove that global warming is not true. Global warming, will cause many problems with the economy and the earth. And we should try to stop it before it becomes a big problem.
