Amazon Drought Releases More CO2 Than US

A Sink Becomes a Source

new study in Science predicts that last year’s drought in the Amazon rainforest, its worst on record, will lead to carbon emissions of about 8 billion metric tons by the end of this year, or 2.6 billion metric tons more than what the United States emitted in 2009. The drought, the study says, created a water deficit that increased tree mortality in three epicenters, hindering the forest’s ability to absorb carbon dioxide. (To visualize the scale of the drought, think of rainfall shortages over an area more than seven times that of California.) What’s most alarming about the Amazon’s droughts, though, is that they’re causing carbon-emission levels high enough to probably cancel out the amount of carbon the forest absorbed over the past decade.
