3,2,1 . . .Blast off!
• Please get out paper and read the board!
• *** Corrected link to second carbon footprint now on the HUB!
The Greenhouse effect
• Solar radiation in with shorter wavelengths• Converted to infrared energy at surface with
longer wavelength• Infrared energy trapped by greenhouse gases
Greenhouse Warming potential
Gas 2010 Concentration
Global warming potential (over 100 years)
Residence time in atmosphere
Water vapor Variable with temperature
<1 9 days
CO2 390 ppm 1 Highly variable
CH4 1.8 ppm 25 12 years
N2O 0.3 ppm 300 114 years
CFCs 0.9 ppm 1,6000 to 13,000 55 to >500 years
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?)
Convection cells
• Movement of air in these cells explains location of rainforests, deserts
• **Hadley cell• Ferrel cell• Polar cell
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
