  1. Human Impacts: Atmosphere

  2. Global Warming Definition: An increase in the average temperature of earth because of an increase in greenhouse gases.

  3. Global Warming Cause: A ‘blanket’ of greenhouse gases keeps Earth warm. Hot dog

  4. Global Warming • Gasses such as carbon dioxide and methane trap heat and help our planet support life. This is called the greenhouse effect. It is normal, and essential to life. Cause:

  5. Global Warming Cause: • Increased production of greenhouse gases has enhanced this warming effect, called global warming.

  6. Global Warming Effect: Changed precipitation patterns. Rise in sea levels and coastal flooding due to melting glaciers.

  7. Global Warming Solution: Reduce carbon dioxide emissions by using less fossil fuel. Explore alternative energy source. Big guy in a little car

  8. Acid Deposition Definition: Rain ( and snow, hail, etc.) with a pH below 5.6 Harmful chemicals settle as “dust”

  9. Acid Deposition Cause: • Sulfur dioxide and nitrogen dioxide pollution from the burning of fossil fuels.

  10. Acid Deposition Cause: Most of New York State’s acid precipitation originates in the mid-west and moves to us in the prevailing winds.

  11. Acid Deposition Effect: Destruction of limestone and marble monuments due to increased chemical weathering Acidification of aquatic ecosystems destroying the life in them.

  12. Acid Deposition Effect: Damage forests and other plants in a variety of ways

  13. Acid Deposition Solution: Reduce emissions sulfur and nitrogen from industry by use of scrubbers etc. Explore alternative energy sources. • . Reduce use of fossil fuel

  14. Ozone Depletion Definition: The reduction of the thin layer of O3 (ozone) that protects the earth from ultraviolet (UV) radiation.

  15. Ozone Depletion Cause: Chloroflurocarbons (CFC’s) pollution from refrigerants and plastics are destroying our thin ozone shield high up in our atmosphere.

  16. Ozone Depletion Effect: It is linked to increased incidence of skin cancers and cataracts in the human population. Increased UV radiation has been linked to amphibian declines.

  17. Ozone Depletion Solution: Ban CFC’s
