The impact of global warming in the Arctic may differ from the predictions of computer models of the region, according to a pair of Penn State biologists. The team - which includes Eric Post, a Penn State associate professor of biology, and Christian Pederson, a Penn State graduate student - has shown that grazing animals will play a key role in reducing the anticipated expansion of shrub growth in the region, thus limiting their predicted and beneficial carbon-absorbing effect...
