Mountain snowpack is shrinking and melting earlier in the spring. Warmer and longer summers dry out vegetation and increase the threat of wildfires in western mountain forests, where the fire season has lengthened by at least a month since 1979. The growing wildfire risk is just part of an accelerating cycle of global warming impacts in the world’s mountain regions, according to a new Intergovernmental Panel on Climate Change report that includes a section focused on mountains for the first time in more than 20 years. “Snow cover duration has declined in nearly all regions, especially at lower elevations, on average by five days per decade,” the mountain chapter of the IPCC report says. On average across Western North America, the European Alps and High Mountain Asia, temperatures are warming by 0.54 degrees Fahrenheit per decade. To view the full article visit Coyote Gulch.
