DN: For each of the following, state what it is, what causes it, and why it is bad for the environment:
Acid Rain
Ozone Depletion
HW: Air Pollution Exam Monday
HW Article and Questions #2
due Friday (BP Oil Spill)

2. A gradual increase in the temperature of the surface of the Earth
Global Warming
A gradual increase in the temperature of the surface of the Earth

3. The Greenhouse Effect The trapping of heat by gases in the atmosphere
Raises the average temperature of the Earth
Why is this needed?
This is needed for life to exist!!!

5. Greenhouse Gases Trap heat
1. Carbon Dioxide burning fossil fuels such as coal, oil and natural gas
2. Methane- decomposing wastes in landfills
Nitrous Oxide- fertilizers
Water Vapor
An increase in greenhouse gases in the atmosphere is caused by burning of fossil fuels.

6. WHAT ARE THE EFFECTS OF GLOBAL WARMING?????

7. 1. Rising Sea Levels Caused by melting glaciers
Flooding of coastal cites

8. 2. Extinction Species may not be able to adapt to change in climate
Decrease in biodiversity

9. 3. Effect on plants and animals
Possible migration to cooler areas
Change in life cycles
Extend time for warmer climate plants

10. 4. Human Health
Increased geographical area for tropical diseases- ideal conditions for many insects such as mosquitoes
Malaria, West Nile Virus, Dengue Fever
cholera

11. 5. Storms Warmer ocean water = more hurricanes
Floods, loss of lives, damage to property

12. 6. Droughts
Crop failure
Decrease in global food production- starvation

13. 7. Economy
Cost of natural disasters
Increase in food and energy costs

14. 8. Ecosystems Land, water, air
