Mid-elevation forests – those between approximately 6,500 to 8,000 feet (1,981 to 2,438 meters) in elevation – are the most sensitive to rising temperatures and changes in precipitation and snowmelt associated with climate change, finds a new University of Colorado Boulder-led study co-funded by NASA. The study looked at how the greenness of Western U.S. forests is linked to fluctuations in year-to-year snowpack. Read more.
