Traumatized Trees: Bug Them Enough, They Get Fired Up http://apocadocs.com/s.pl?1271269937
Whether forests are dying back, or just drying out, projections for warming show the Pacific Northwest is becoming primed for more wildfires. The area burned by fire each year is expected to double -- or even triple -- if temperatures increase by about 3.5 degrees Fahrenheit (2 C) in our region, according to University of Washington and USDA Forest Service research... "The difference between now and our prior history is the magnitude of the impact," said Elaine Oneil, UW research associate in forest resources. "We basically have massive bark beetle outbreaks in the western U.S. and Canada over the entire extent of pines that are susceptible. We're seeing these massive mortality events of millions and millions of acres."
