1. WARM UP /2/14
Describe the climate in each of these regions. Remember to include both TEMPERATURE and PRECIPITATION in your descriptions.
Dry
Highland
Polar
Humid mid-latitude
Humid tropical

2. Greenhouse Effect
Water vapor and carbon dioxide – major greenhouse gases
Trap heat in our atmosphere
Without the greenhouse gases, Earth would be too cold to live on

3. Example of the Greenhouse Effect
The Sun’s energy passes through the car’s windshield.
This energy (heat) is trapped inside the car and cannot pass back through the windshield, causing the inside of the car to warm up.

5. What are the 2 major greenhouse gases?

6. Greenhouse Effect Humans can impact the greenhouse effect
Burning of fossil fuels releases CO2 into the atmosphere
Increasing the amount of carbon dioxide which causes temperatures to increase beyond the normal amounts

7. What’s the difference between “global warming” and “climate change”?

8. Difference
GLOBAL WARMING is the increase of the Earth’s average surface temperature due to a build-up of greenhouse gases in the atmosphere.
CLIMATE CHANGE is a broader term that refers to long-term changes in climate, including average temperature and precipitation.

9. Global Warming
Global warming – increase in global temperatures from an increase in carbon dioxide
Might lead to the melting of the glaciers
Would raise sea level 60 meters and would flood coastal towns

10. Effects of Global Warming
Rising Sea Level
Increased Temperature
Habitat Damage and
Species Affected
Changes in Water Supply

12. What are 2 possible effects of global warming?

13. Measuring Global Warming
Temperatures in the Northern Hemisphere from 200 A.D. – 2000 A.D.
At the start of the Industrial Revolution – temperatures began to rise and have continued

14. Global Warming: Shifting Gears

15. Billions of Metric Tons Carbon
Goal: Reductions in
CO2 Per Year
2007

16. Billions of Metric Tons Carbon
Our Goal
Produce electricity efficiently
Use electricity efficiently
Vehicle efficiency
Solar and Wind Power
Biofuels
Carbon capture and storage
Billions of Metric Tons Carbon
Gigaton Carbon
Reductions in CO2
Per Year
2007

17. Measuring Global Warming
Arguments that skeptics of global warming put forth:
Before humans the Earth went through climate shifts
There is not enough evidence
2009-Global warming activists knowingly submitted false data to forward their agenda
