Alaska's Boreal Forests Burning More with Climate Change

The largest U.S. wildfires in the last decade of record-breaking blazes have been in the wilds of Alaska, where fires have blackened more than a half-million acres at a time.

A new study predicts more of the same for all of North America’s boreal forests, the Far North belt of spruce and fir trees that extends from interior Alaska across Canada.

A warming climate could promote so much wildfire in the boreal zone that the forests may convert to deciduous woodlands of aspen and birch, researchers said.
