Obama fiscal plans strive for breakthrough energy research and low-carbon transportation

Pine bark beetles poised for new attacks on Canada's northern and eastern forests
After more than a decade, the mountain pine beetle epidemic that surged through British Columbia appears finally to be in remission. Having devastated the province's lodgepole pine forests, the insect is running out of food. But forest managers now see new beetle infestations appearing at the edge of the Boreal Forest, in Alberta, and in the Yukon and Northwest Territories -- areas well outside the insect's historical range. As a warming climate lifts the temperature limitations that once kept the beetle in check, scientists fear it may continue its push across the continent, perhaps as far as the Atlantic Coast.
