Deforestation effects depend on location

The effect of deforestation on climate depends on three things — location, location and location.

Environmentalists concerned about global warming have long encouraged preservation of forests because they absorb carbon dioxide, the most abundant greenhouse gas in the atmosphere.

But the issue, like most things, may be more complicated than it first appears.

New research in this week’s online edition of Proceedings of the National Academy of Sciences, confirms the effectiveness of tropical forests at reducing warming by absorbing carbon. But it suggests that in snowy latitudes, forests may actually increase local warming by absorbing solar energy that would otherwise be reflected back out into space.
