Twelve national parks in the West are under serious threat from climate change. That’s the message of a new report from the NRDC and the Rocky Mountain Climate Organization, “Losing Ground.” According to the report, the parks in 11 western states are “endangered” as a result of climate change-related phenomena including drought, decreased snowfall, and wildfire. The report says landscapes in these national parks could be “drastically altered” if nothing is done to stave off the potential impacts of global warming. (An RMCO report released last summer showed western temperatures on the rise and snowflakes in decline.)
