Since the early 1970s, less snow has fallen in nearly two-thirds of snow stations across the country, according to research group Climate Central, which decades of annual snowfall trends in over 2,041 locations.
In the Mountain West, snowfall has decreased in many areas of Nevada, Idaho, Wyoming, Colorado, New Mexico, and Utah. What鈥檚 more, some of the nation鈥檚 steepest declines are in the region. Notable examples include Gascon, N.M., where snowfall has decreased by 76 inches; Red Lodge, Mont. (69 inches); Crested Butte, Colo. (65 inches); Ruxton Park, Colo. (59 inches); and Fillmore, Utah (50 inches).
Each state has a few areas where snowfall has increased over the past 50 years. But the broader trend of less snowfall, which impacts the West in many ways, is driven by human-caused climate change, said Kaitlyn Trudeau, a senior research associate at Climate Central.
鈥淲hat winter means, what snow means to people culturally, just for our environment, and for our ecosystems, for our water supplies, it鈥檚 just incredibly important,鈥� Trudeau said. 鈥淎s we see snowpack decline, it not only means that we have more unstable and less water resources, but it also means that it's going to take a big hit on the mountain economies, the places where they really rely 鈥� ski resorts, snow parks.鈥�
Less snow is also bad for farmers, who face the risk of not having enough water to irrigate their crops.
