A new study led by Northern Illinois University scientists suggests American winters late this century could experience significant decreases in the frequency, intensity and size of snowstorms.
Under an unabated greenhouse gas emissions scenario, the study projects 28% fewer snowstorms on average per year over central and eastern portions of North America by the century’s last decade, with one-third the amount of snow or frozen precipitation and a 38% loss in average snowstorm size.
“If we do little to mitigate climate change, the winter season will lose much of its punch in the future,” said Walker Ashley, an NIU professor of meteorology and lead author of the study, published today (May 25) in Nature Climate Change.
