1. Climate Change

2. Some Climate Change Statistics
2007: Intergovernmental Panel on Climate Change (IPCC)
Oceans will rise 7-23 inches by year 2100
90% certain that humans caused accelerated warming of 20st century
Higher CO2  Global Warming  Climate Change
Changes timing & length of seasons
Changes rainfall amounts

3. Climate Change
Climate change: significant, long-lasting changes in weather patterns
Includes…
Intensity of weather
Number of severe weather events
Regional or Global

4. Is Climate Change the same as Global Warming?
No!
Global warming contributes to climate change
Warmer temperatures affect world weather patterns:
Rainfall amounts
Storms
Droughts
Sea Level

5. -OZONE (O3) -CFCS? -WHY DO WE NEED OZONE?
So what is Ozone?!

6. Greenhouse Gases
Greenhouse Gases are naturally present in the Earth’s atmosphere
GGs help maintain a “healthy” global temperature by trapping heat
Greenhouse Gases:
Water vapor (H2O)
Carbon Dioxide (CO2)
Methane (CH4)
Nitrous Oxide (N2O)
Ozone (O3)

7. Greenhouse Effect
“The Greenhouse Effect”: the “trapping” of heat by greenhouse gases in the atmosphere
The “trapped” warms the Earth
Greenhouse Effect is NORMAL, but has been amplified by human production of CO2

8. How does it work?

9. Humans  CO2 Production  Global Warming  Climate Change

10. Before Global Warming

11. After Global Warming

12. VERY close to ocean
Result of coastal erosion

13. So…
Officials had to move Cape Hatteras Lighthouse 2,870 feet inland!

14. Peterman Glacier, Greenland
