  1. The Chemistry of Climate Change

  2. Greenhouse Effect 300 nm

  3. Greenhouse Gases Species Absorption Region Estimated Global Warming H2O 2.5, 3.5, 5-7 mm ~110 Wm-2 CO2 14-19 mm ~50 Wm-2 CH4 3-4, 7-8.5 mm ~1.7 Wm-2 O3 9-10 mm ~1.3 Wm-2

  4. Global Warming Potential Due to species i Due to CO2 Radiative forcing (net change in the flow of radiative energy per unit mass) Concentration of Greenhouse gas

  5. Global Warming Potential Climate Change Indicator Integration Time Period Maximum change in Temperature ~100 years Rate of change in Temperature ~20-50 years Maximum change in Sea Level >100 years Rate of change in Sea Level >50 years
