"Researchers found that across 195 US cities, winters are on average nine days shorter today than they were from 1970 to 1997, as the climate crisis progresses. For the purposes of the study, analysts defined winter as the coldest 90 consecutive days of the year during the past period, 1970-1997, and then compared the frequency of winter-like temperatures during the most recent 28-year period, 1998-2025."
"Across the country, they found that winter-defining temperatures are arriving later and ending earlier than in the 20th century. Cities across the US south-east, north-east, upper midwest and south have experienced the largest average decrease in winter days, according to the research. Juneau and Anchorage in Alaska have seen winters shrink the most, by 62 and 49 days, respectively."
"A shorter winter doesn't mean no winter, Mathew Barlow, professor of climate science at the University of Massachusetts Lowell, said on Friday. Another important piece of [research] is that we expect greater precipitation intensity as the climate warms."
Climate Central researchers analyzed 195 US cities and found that winters have shortened by an average of nine days since the 1970s-1990s. Winter-defining temperatures now arrive later and end earlier than in the 20th century. The Southeast, Northeast, Upper Midwest, and South experienced the largest decreases in winter days. Juneau and Anchorage, Alaska saw the most dramatic reductions, losing 62 and 49 days respectively. About 15% of analyzed cities experienced longer winters, primarily along the California coast and Ohio valley. Despite shorter overall winters, climate scientists note that warmer temperatures increase precipitation intensity, explaining severe winter storms like recent nor'easters.
