NIPCC IR1 - Chapter 2 - Forcings and Feedbacks

August 29, 2011

Chapter 2 summarizes the latest research on what is known about forcings and feedbacks. While rising levels of atmospheric carbon dioxide (CO2) would increase global temperatures through its thermal radiative properties, all else being equal, all else is not equal. More CO2 promotes more plant growth both on land and throughout the surface waters of the world’s oceans, and this vast assemblage of plant life has the ability to affect Earth’s climate in several ways, almost all of them tending to counteract the heating effects of CO2’s thermal radiative forcing.
