Unformatted text preview: Env 100 Lab 8 Climate Change Name: Section: 1. What’s the difference between climate and weather? 2. Explain what a greenhouse gas is and list 3. 3. Explain how the Earth's orbit affects its climate. 4. What are these cycles called? Go to http://climate.nasa.gov/ on the right click on NASA climate time machine, and then click on sea ice. 5. How has the arctic ice behaved through time? Click on average global temperature. 6. Slide the bar and watch what happens. How has the average temperature of the earth changed? Click on sea level rise 7. What’s the smallest rise in sea level to flood New Orleans, LA? Click on CO2 emissions 8. How much more CO2 did China produce in 2004 vs. 2000 9. How much more CO2 did the United States produce in 2004 vs. 1980 10. Why is there such a drastic change in CO2 emissions from Russia between 1991 and 1992? Think major world history event. Go to http://flood.firetree.net/?ll=43.32517767999296,‐101.6015625&z=13&m=7 11. Set the meter scale to 0m and look at the map of the world. What areas look vulnerable to flooding? 12. Zoom in to the following areas and fill in the chart below. Change the meter scale to the different levels of sea level rise as indicated. Describe what happens. 3m rise 5m rise 10m rise Area San Francisco Area New York City Washington, DC Temperature Anomaly data for 1900 through 2004 for 3 latitudinal bands 1 0.8 0.6 0.4 0.2 0 1880 ‐0.2 ‐0.4 ‐0.6 1900 1920 1940 1960 1980 2000 2020 North 90N‐23.6N Temperature Anomaly data for 1900 through 2004 for 3 latitudinal bands 0.8 0.6 0.4 0.2 0 1880 ‐0.2 ‐0.4 ‐0.6 1900 1920 1940 1960 1980 2000 2020 Tropics 23.6N‐2 3.6S Temperature Anomaly data for 1900 through 2004 for 3 latitudinal bands 0.5 0.4 0.3 0.2 0.1 0 ‐0.11880 ‐0.2 ‐0.3 ‐0.4 ‐0.5 1900 1920 1940 1960 1980 2000 2020 South 23.6S‐90S 13.
