The trees and vegetation of the Amazon Rainforest in Brazil soak up massive amounts of CO2 - a greenhouse gas responsible for global warming - but also release massive amounts when they die. Two major droughts there in 2005 and 2010 have caused the Amazon to be a source of CO2 not a sink, potentially fueling further global warming.
"The combined emissions caused by the two droughts were probably enough to have canceled out the carbon absorbed by the forest over the past 10 years, the study found."
