Global Warming May Reroute Evolution

 Rising carbon dioxide levels associated with global warming may affect interactions between plants and the insects that eat them, altering the course of plant evolution, research at the University of Michigan suggests.

Arctic Continues to Warm at Unprecedented Rate

The Arctic region, also called the "planet's refrigerator," continues to heat up, affecting local populations and ecosystems as well as weather patterns in the most populated parts of the Northern Hemisphere, according to a team of 69 international scientists.

Warmer Arctic probably permanent

The signs of climate change were all over the Arctic this year -- warmer air, less sea ice, melting glaciers -- which probably means this weather-making region will not return to its former, colder state, scientists reported.

Genetically Altered Trees, Plants Help Counter Global Warming

Forests of genetically altered trees and other plants could sequester several billion tons of carbon from the atmosphere each year and so help ameliorate global warming, according to estimates published in the October issue of BioScience. The study, by researchers at Lawrence Berkeley National Laboratory and Oak Ridge National Laboratory, outlines a variety of strategies for augmenting the processes that plants use to sequester carbon dioxide from the air and convert it into long-lived forms of carbon, first in vegetation and ultimately in soil.
