Warming Climate Threatens Alaska's Forests

Reuters reports that climate change will effect Alaska more than any other US state and that - since the state is one-third forest - the effects will take the form of droughts, forest fires, and infestations of tree-killing insects - though further north near the arctic circle, receding sea ice will have major implications for polar bears, seals and dozens of other species, not to mention native humans who depend on the land and animals to sustain them.
