Rocky Mountain Forests at Risk: The Growing Impacts of Climate Change

Tens of millions of trees have died in the Rocky Mountains over the past 15 years, victims of a triple assault of tree-killing insects, wildfires, and stress from heat and drought.
Global warming is the driving force behind these impacts, bringing hotter and drier conditions that amplify existing stresses, as well as cause their own effects.
The future of Rocky Mountain forests depends on us -- how much and how quickly we curb the heat-trapping emissions that are causing climate change.
