Climate Change 2001:
Working Group II: Impacts, Adaptation and Vulnerability
Milder winter temperatures will decrease heavy snowstorms but could cause an increase in freezing rain if average daily temperatures fluctuate about the freezing point.
As Trenberth explained, the ideal temperature for a blizzard is just below freezing — just cold enough to crystalize water into snow.
“In the past, temperatures at this time of year would have been a lot below freezing,” Trenberth said. In other words, it’s been too cold to snow heavily.
Michael Oppenheimer, a climate change expert at Princeton University, said global warming is increasing extreme storms. “Storms like this tend to be heavier than they used to be,” he told HuffPost. “That’s a fact.”
Clearly, the science has settled to the climate phenomena of moreless snow.
