2. 3,2,1...Blast off! Please get out paper and read the board! *** Corrected link to second carbon footprint now on the HUB!

4. The Greenhouse effect Solar radiation in with shorter wavelengths Converted to infrared energy at surface with longer wavelength Infrared energy trapped by greenhouse gases

5. Greenhouse gases CO 2

6. Methane CH 4 (25x more heat trapping ability than CO2!)

7. N 2 O Nitrous Oxide

8. Water!

9. CFC’s (chlorofluorocarbons)

10. And O 3

11. Greenhouse Warming potential Gas2010 Concentration Global warming potential (over 100 years) Residence time in atmosphere Water vaporVariable with temperature <19 days CO 2 390 ppm1Highly variable CH 4 1.8 ppm2512 years N2ON2O0.3 ppm300114 years CFCs0.9 ppm1,6000 to 13,00055 to >500 years

12. Atmosphere diagram – the last story! Sources on this sheet just like the others Show primary pollutants coming from each source correctly (greenhouse gases) Draw in greenhouse effect in green (get it?)

13. Why are these biomes in these places? What shapes climate?

14. Latitude – distance from equator

15. Convection cells Movement of air in these cells explains location of rainforests, deserts **Hadley cell Ferrel cell Polar cell

16. Earth’s axis – 23 o tilt = seasonality

17. Ocean currents also affect biome distribution.

19. Rome is same latitude as New York!

20. El Nino Normal conditions: winds blow west, cold waters rise El Nino: winds stop blowing, warm waters in Eastern Pacific block cold waters Effects: disrupt marine ecosystems, major weather changes over 2/3 Earth

21. La Nina

23. El Nino Southern Oscillation vs. La Nina

24. Check for understanding Name the 6 green house gases. What human activities create CH 4 ? Is the greenhouse effect beneficial or negative? What energy type reaches the earth from the sun?
