In this handout photo provided by the US Forest Service in Juneau from 2009, a yellow cedar tree is shown near Thorne Bay, Alaska. U.S. Forest Service researchers have confirmed what has long been suspected about a valuable tree in Alaska's Panhandle: a warming climate is killing off yellow cedar. The mighty trees can live more than 1,000 years, resisting bugs and rot and even defending themselves against injury, but their shallow roots are vulnerable to freezing if soil is not insulated by snow.
