Careful Where You Put That Tree 190

Ant writes "Wired News is reporting that according to Stanford University's atmospheric scientist Ken Caldeira, forests in the wrong location can actually make the Earth hotter. From the article: 'Plants absorb large amounts of carbon dioxide during photosynthesis, so scientists and policy makers have long assumed new forest growth helps combat global warming. At an American Geophysical Union conference in San Francisco earlier this month, however, Caldeira rolled out a provocative new finding: Trees may be good at capturing carbon dioxide from the atmosphere, but their dark leaves are also very efficient at soaking up sunlight, which is later released as heat. At certain latitudes, the net effect of these two processes is warming, rather than cooling.'"
