The Amazon — the greatest carbon dioxide sink of them all, the lungs of our world — has flipped from a carbon sink to a carbon source; but for a different reason.In 2005 the Amazon experienced a 100-year drought, and then in 2010, a drought significantly more extreme. Billions of trees were killed. Because dead trees do not absorb carbon dioxide and instead emit it as they decompose, instead of absorbing carbon dioxide and helping stabilize our ever-increasing climate pollution emissions, the Amazon is now emitting half as much carbon dioxide as Brazil emits every year.
