Colorado snowpack may shrink as climate change alters ski seasons

Average temperatures in Colorado have risen about 2 degrees since 1980, and scientists report warmer fall and spring temperatures are already bringing more rain instead of snow and earlier spring melt that shortens late-season ski days.

Colorado's alpine ski areas have long faced variable winter weather, from heavy blizzards to periodic snow droughts. Reporting finds that average temperatures across the state have risen about 2 degrees since 1980. Scientists say warmer conditions are already appearing at the start and end of the ski season. The series gathered scientific studies and interviews with researchers, industry groups and resort operators to examine how snowpack and skiing may change. Key observations: - Average temperatures across Colorado have risen about 2 degrees since 1980, as reported. - Warmer conditions at the beginning and end of the season are increasing the likelihood that rain will replace snowfall in the fall and spring, especially at lower elevations. - Earlier spring melt and faster snow loss are reducing late-season ski days and affecting snow quality. - Resorts are investing more in snowmaking and adjusting business practices, and major ski companies vary in how loudly they call for policy responses to climate change. Summary: Projected warming is likely to shorten early- and late-season skiing windows and change snow quality, with economic consequences for resorts and the wider ski industry. Undetermined at this time.
