We shold be parading the heads of the carbon company execs around on pick staffs. The future is looking short and pain filled.

More bad news comes from a recently published study showing that Earth's vegetation could be saturated with carbon by the end of this century, and would thus cease acting as a break on ACD. However, this study could be an under-estimate of the phenomenon, as it is based on a predicted 4C rise in global temperature by 2100, and other studies and modeling predict a 4C temperature increase far sooner. (The Hadley Centre for Meteorological Research suggests a 4C temperature increase by 2060. The Global Carbon Project, which monitors the global carbon cycle, and the Copenhagen Diagnosis, a climate science report, predict 6C and 7C temperature increases, respectively, by 2100. The UN Environment Program predicts up to a 5C increase by 2050.)

Whenever we reach the 4C increase, whether it is by 2050, or sooner, this shall mark the threshold at which terrestrial trees and plants are no longer able to soak up any more carbon from the atmosphere, and we will see an abrupt increase in atmospheric carbon, and an even further acceleration of ACD
