The Average Winter Temperature in the U.S. Has Risen Drastically Over the Last Century - SnowBrains

"The data shows that winter temperatures have increased by nearly 4 degrees Fahrenheit in 98% of the cities studied. Salt Lake City, Utah, a major ski destination, has seen winter temperatures rise by roughly 3 degrees since 1970. Because much of the Salt Lake Valley depends on mountain snowpack for both recreation and water supply, even small temperature increases threaten snow reliability at higher elevations."

"More northern cities such as Detroit and Boston recorded even larger changes, with some locations experiencing winter temperature increases of 7 to 8 degrees over the 50-year period.

Average temperatures across the United States have risen substantially over the past 50 years, with winter showing the largest increases. Winter temperatures increased by nearly 4°F in 98% of studied cities, and some northern locations rose 7–8°F. Salt Lake City’s winter temperatures rose roughly 3°F since 1970, threatening mountain snowpack that supports recreation and water supply. Warmer winters produce poorer snow quality, reduced snowfall, shorter seasons, and more hazardous conditions for skiers and snowboarders. Broader consequences include melting polar ice, rising sea levels, more frequent and intense disasters, and prolonged droughts, amplifying stress on winter sports and water resources.
