A new study in the journal Science shows that the Amazon suffered a serious drought last year—making for two severe droughts in the world's biggest rainforest within five years, and raising disturbing implications for global climate. While the Amazon normally absorbs huge amounts of CO2, droughts cause the reverse effect—with the forests releasing emissions as dead trees decay. Emissions from last year's drought may exceed the 5 billion tons of CO2 that the last drought in 2005 is believed to have released. This is roughly equal to the annual emissions of the United States.

Brazil's National Indigenous Foundation (FUNAI) has released new photographs of an isolated tribe living in a remote rainforest region of Acre state near the Peruvian border. FUNAI has been monitoring "uncontacted" tribes—those with only limited dealings with the outside world—from the air in recent years. Photographs of what is believed to be the same tribe were released to the world two years ago. Campaigners say the tribe, believed to be part of the Panoan indigenous group, are threatened by a rise in illegal logging on the Peruvian side of the border.
