In 2010, dry-season rainfall was low across Amazonia, with apparent similarities to the major 2005 drought. We analyzed a decade of satellite-derived rainfall data to compare both events. Standardized anomalies of dry-season rainfall showed that 57% of Amazonia had low rainfall in 2010 as compared with 37% in 2005 (≤–1 standard deviation from long-term mean). By using relationships between drying and forest biomass responses measured for 2005, we predict the impact of the 2010 drought as 2.2 × 1015 grams of carbon [95% confidence intervals (CIs) are 1.2 and 3.4], largely longer-term committed emissions from drought-induced tree deaths, compared with 1.6 ×1015 grams of carbon (CIs 0.8 and 2.6) for the 2005 event.

Cenários espaçotemporais para o desmatamento na Amazônia Legal brasileira
Pesquisadores do IPAM (Instituto de Pesquisa Ambiental da Amazônia) criaram, em parceria com o Banco Mundial, uma plataforma onde é possível prever o risco de desmatamento e estimar as áreas futuramente desmatadas nos estados da Amazônia Legal. A pesquisa pretende...
