1. Global Warming

2. Global Warming vs. Greenhouse Effect
Def: Increase of the Earth’s temperature due to the greenhouse effect

3. The Earth’s atmosphere acts like a piece of glass in a greenhouse.

4. Gases Responsible for Global Warming
1) Carbon Dioxide (CO₂)
Major gas responsible for global warming
Major sources of CO₂ are Electric utilities and transportation

5. 2) Chloroflorocarbons (CFC’s)
Major source: refrigerant , used to make Styrofoam and clean electrical circuits

6. 3) Methane gas Major sources:
Decomposition of organic matter (landfills, swamps)
Cows
Fracking
As the earth warms and the ice melts a major fear is that the amount of methane in the atmosphere will increase due to the escape of methane that is trapped in ice.

7. Effects of Global Warming
1) Change in Weather Patterns

8. 2) Shift in Biomes

9. Change in temperature over years
Temperature change from

10. Spread of Infectious Diseases
As Temperature increases, mosquitoes and other disease vectors move to more areas

11. Spread of Malaria

12. 3) Melting of ice caps
Break up of pack ice
Increase in Sea levels

13. How would Florida and Louisiana be affected?

14. 4) More severe storms (hurricanes/tornados)
The number and severity of hurricanes has increased .
In the U.S., hurricanes in the past 10 years have caused major damage. (Katrina)

16. Solutions to Global Warming
1) Stop or slow deforestation
Trees absorb carbon dioxide

17. 2) Reclaim CFC’s from refrigerators, etc

18. 3) Turn to a renewable energy source
