Document Summary

Global mean energy budget under present day climate conditions: worried about clouds, surface and atmosphere, not worried about the sun budget. Climate sensitivity: the amount of global average surface warming following a doubling of carbon dioxide concentrations: average is 2 degrees celsius to 4. 5 degrees celsius. Radiative forcing: measure of contribution of a greenhouse gas to the atmospheric greenhouse effect: refers to change in outgoing infrared flux due to the change in the concentration of a particular greenhouse gas. Measures from surface to top of the atmosphere.
