Scientists fear billions of tree deaths caused by a 2010 drought in the Amazon region of South America could see the vast forest turn from a carbon sink to a carbon source. Billions of trees died in the record drought that struck the Amazon in 2010, raising fears that the vast forest is on the verge of a tipping point, where it will stop absorbing greenhouse gas emissions and instead increase them. The dense forests of the Amazon soak up more than one-quarter of the world’s atmospheric carbon.
