A new report from the Union of Concerned Scientists (UCS) and the Rocky Mountain Climate Organization found that forests in Yellowstone, Grand Teton and Glacier National Park are facing annihilation from the skyrocketing incidents of heat, wildfires, tree-killing insects and drought.
The culprit behind it all?
“No obvious cause.”
That’s right. The study basically concluded with a collective shoulder shrug.
According to the article, “Trees Are Dying From ‘No Obvious Cause’ In Rocky Mountains, Report Says”, by Ari Phillips (@re_ari) on Climate Progress, the scientists only slightly allude to these changing conditions being the result of climate change.
Trees Are Dying From ‘No Obvious Cause’ In Rocky Mountains, Report Says
By Ari Phillips, Climate Progress, September 11, 2014
The Rocky Mountain forests that traverse the West are under unprecedented danger from climate-related impacts according to a new report from the Union of Concerned Scientists (UCS) and the Rocky Mountain Climate Organization. The Rockies include national parks like Yellowstone, Grand Teton, and Glacier National Park, and are facing a “triple assault — tree-killing insects, wildfires, and heat and drought — that could fundamentally alter these forests as we know them.”
According to the report, titled “Rocky Mountain Forests at Risk,” many western trees are dying from “no obvious cause” like the bark beetle epidemic or increasing threat of wildfire, with scientists suggesting that these deaths are due simply to the hotter and drier conditions associated with climate change. The mortality rate for old-growth trees in undisturbed forests has doubled recently, with a sharp increase in recent years, and there’s been no compensating increase in the number of seedlings.
