New Study shows Rocky Mountain forests threatened by climate change and associated events

Experts from the Union of Concerned Scientists and the Rocky Mountain Climate Organization have released a new report, which documents how Rocky Mountain forests are under an unprecedented triple assault from wildfires, tree-killing insects, and heat-and drought-related stress—all fueled by climate change.

The report authors say bark beetle infestations have killed trees faster and on a larger scale than ever seen in U.S. history; wildfires in the West are burning nearly seven times more forests than 30 years ago; and tree deaths in undisturbed forests have doubled in recent decades, with a sharp increase in recent years, linked to periods of extreme heat and drought.
