  1. - Glacial Melting
    - Flooding of Coasts
    - Changes in climate( change in crops and soils are not appropriate in other regions)
    - Atmosphere Changes ( More hurricanes and storms)
  2. The global sunscreen
    Ozone Layer
    1. Ozone is produced when oxygen molecules interact with lightning and UV radiation from the sun
    2. Keeps 99% of the suns harmful UV radiation from reaching Earths surface
    3. Helps protect human skin cancer, cateracts, sun burns, and damage to the immune system
    4. Protects plants and animals and prevents O2 from changing to O3
  3. 1. The amount of CO2 in the atmosphere is increasing by .4% per year
    2. The net effect would be an increase in the global temperature of about 2 degrees Celsius by 2100
    3. Gasses leading to global warming
    - Methane
    - Chlorofluorocarbons
    - Nitrous Oxide
  4. 1. At the poles
    2. Austrilla
    3. New Zealand
    4. South Africa
  5. 1. It would cost about $27 trillion for the US to lower CO2 emissions by 70% in the next 40 years
