A study published in Nature Climate Change today finds that tropical vegetation contains 21 percent more carbon than previous studies had suggested. Using a combination of remote sensing and field data, scientists from Woods Hole Research Center (WHRC), Boston University, and the University of Maryland were able to produce the first "wall-to-wall" map (with a spatial resolution of 500 m x 500 m) of carbon storage of forests, shrublands, and savannas in the tropics of Africa, Asia, and South America.

Articles in this series focus on the central arguments in the climate debate and examine the evidence for global warming and its consequences.

WISE RIVER, Mont. — The trees spanning many of the mountainsides of western Montana glow an earthy red, like a broadleaf forest at the beginning of autumn.

Estudo defende áreas protegidas como forma eficiente de evitar desmatamento no Brasil.

Estudo divulgado pela publicação “PLoS Biology” ressalta a importância das áreas protegidas para evitar a emissão de gases causadores do efeito estufa por desmatamento. Segundo o artigo, assinado por 13 pesquisadores de instituições dos EUA, Brasil e Europa, a criação e manutenção de áreas indígenas e outros tipos de reserva têm se mostrado uma forma relativamente barata e eficiente de amenizar a devastação.
