Scientists report that, between 1990 and 2007, the world’s forests stored about 2.4 gigatons of carbon per year.

Their results suggest that forests account for almost all of the world’s land-based carbon uptake. Boreal forests are estimated to be responsible for 22 percent of the carbon stored in the forests. A warming climate (AGW) has the potential to increase fires and insect damage in the boreal forest and reduce its capacity to sequester carbon.
