Amazon drought 'severe' in 2010, raising warming fears

[muriel_volestrangler]

Last year's drought in the Amazon raises concerns about the region's capacity to continue absorbing carbon dioxide, scientists say.

Researchers report in the journal Science that the 2010 drought was more widespead than in 2005 - the last big one - with more trees probably lost.

The 2005 drought had been termed a "one in a century" event.

In drought years, the Amazon region changes from being a net absorber of carbon dioxide into a net emitter.
