"Shift in Boreal Forest Has Wide Impact"

"Boreal forests across the Northern hemisphere are undergoing rapid, transformative shifts as a result of a warming climate that, in some cases, is triggering feedback loops producing even more regional warming, according to several new studies.

Russia's boreal forest - the largest continuous expanse of forest in the world - has seen a transformation in recent years from larch to conifer trees, according to new research by University of Virginia researchers.

In Alaska, where the larch were largely devastated by a disease outbreak in the late '90s, vast swathes of forest are becoming inhospitable to the dominant white and black spruce."
