Researchers warn that sea levels will rise much faster than expected
COPENHAGEN -- By the end of the century, sea levels may rise twice as much as was predicted two years ago in the fourth assessment report by the U.N. Intergovernmental Panel on Climate Change. This means that the lives of some 600 million people living on low-lying islands, as well as those living in Southeast Asia's populous delta areas, will be put at serious risk if climate change is not quickly and radically mitigated.

Changing the carbon cycle of eastern U.S. forests, one hemlock at a time
There is a killer stalking the eastern hemlocks of Southern Appalachia, and it is weakening the ability of forests in the region to capture carbon dioxide emissions that are accelerating climate change. Researchers from the U.S. Forest Service recently reported that the killer, a non-native insect from Asia known as the hemlock woolly adelgid, could decimate hemlocks in this area within 10 years and forever change the structure and function of forests in the southern Appalachian region.
