Continued death of forests predicted in southwestern US due to climate change
If current climate projections hold true, the forests of the Southwestern United States face a bleak future, with more severe -- and more frequent -- forest fires, higher tree death rates, more insect infestation, and weaker trees. The findings by university and government scientists are published in this week's issue of the Proceedings of the National Academy of Sciences (PNAS).
