Document Summary

James hansen"s great mental image of the result: 2 tiny 1-watt bulbs over every square meter of earth"s surface, the extra energy thats retained in atmosphere. There are 2 ways to picture this surplus energy caused by excess ghg"s: The extra energy is forcing (climate shifts), forcing put more energy in the climate system, with more energy trapped by extra ghg"s. Changing the average (mean) climate, or changes the variance of the climate. Think of forcing a bell curve to shift right or flatten, be more variable. This is the diagram on nov1 lecture notes. What term is used partly depends on how one sees climate change. The rest of the notes is after the second quiz. More history of climate change science ( how we get to now): Remember the balance of nature view: one cause of it: humans too puny and weak to affect nature, today this has changed, humans are actually powerful.
