There is a complex, counterintuitive relationship between rising global temperatures and the likelihood of increasingly intense snowstorms across Canada. Winters are becoming on average milder and warmer than they used to be, but there has also been a noted rise across the country in extreme weather events, such as intense snowstorms, said John Clague, a professor of geosciences at Simon Fraser University, in Burnaby, B.C.People might think it illogical that parts of the country are seeing more snowstorms as the climate warms, he said. “What climate modelers are finding is that climate change involves more frequent extremes.”
