  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.
