1. GLOBAL WARMING By: Jennifer Travis

2. What is Global Warming?  Global Warming is the increase in the temperature of the worlds atmosphere caused by greenhouse gases.  In the past 100 years, the earths average surface temperature has increased by 0.8°C with 2/3 occurring just in the past 3 decades.

3. What causes Global Warming?  Carbon dioxide emissions from fossil fuel burning power plants.  Carbon dioxide emissions from burning gasoline for transportation.  Methane emissions from animals, agriculture such as rice paddies, and from Arctic sea beds.  Deforestation, especially tropical forests for wood, pulp, and farmland  Increase in usage of chemical fertilizers on croplands

4. What effect does Global Warming have on our earth?  An increase in temperature will cause sea levels to rise and will change the amount of precipitation.  It will cause more extreme weather conditions such as heat waves, drought, and heavy rainfall.  The Arctic Tundra is melting which may cause an increase in methane levels in the atmosphere.  Due to the climate, the agricultural market has become unstable, less efficient and therefore more expensive.  Animals species will become wiped out.
