The droughts associated with recent research findings suggest that rising CO2 will rapidly increase the frecuency and severity of droughts in the region.
The implications for people and biodiversity are unpromising.
Research at Instituto de Pesquisa Ambiental da Amazonia shown.
The drought results from a combination of above normal temperatures over much of the region combined with low precipitation.
We can see in the figure that most of the Amazon region received less than 75 percent of normal rainfall between 1 July and 30 September.
Large areas have received far less precipitation, in many cases less than 25 % of normal.
