Document Summary
Week eleven geog 1350 earth: hazards and global change march 27th. Reponses time a measure of the time it takes the climate system to react fully to some imposed change in the forcing. Rates of forcing vs response: if forcing is slow compared to the climate systems response. An example of climate change that occurs over long time periods. Ex: tectonic forcing: if forcing is fast compared to the climate systems response. Little or no response to the climate forcing. Very few examples of brief forcing and climate response. Slightly longer time scale mount pinatubo eruption in 1991. Fine particles emitted blocked the sun"s radiation and caused average temperature to drop (0. 5: if time scales of forcing and response are nearly equal. Varying degrees (intensities) of response to forcing. Length of on" time directly effects magnitude of response. Flickering switch: but again on/off" climate forcing are rare.
