GEOG 001 Chapter Notes - Chapter 13: Runaway Greenhouse Effect, Greenhouse Gas, Keeling Curve
Document Summary
Kind of the gold standard on climate change. They have been around for a really long time, there are a bunch of reports that they have done. Mission: analyze best available data to develop predictions of the course of climate change: Co2 from fossil fuel burning (big one!) Methane (ch4) rice fields and ruminant gas production (burping and flatulence = Release of methane from tundra and marine sediments release enhanced by warming of environment potential for runaway greenhouse effects. The keeling curve: co2 vs. time and season. 50 years of data of rising co2. Undeniable that were seeing changes in co2 and temperature. Vostok-antarctica ice core: (vostok in russian part of antarctica: a 420,000 year record from core of ice 3,623 in length. Nobody is arguing that the earth is getting warmer, people are arguing about how it is getting warmer. ** natural factors (forcings) alone cannot explain recent temperature anomalies (variations)
