Does Record Snowfall Disprove Global Warming? 'Exactly the Opposite,' Scientist Says

he lakefront city of Erie, Pa. has been inundated by several feet of snow this week, “shattering many records," the National Weather Service said.

The historic storm—a whopping 62.9 inches since Dec. 23, with more flakes to come—prompted the city's police department to declare a “Snow Emergency" due to dangerous and impassable roads.

While climate deniers might point to the cold weather as more proof of the "global warming hoax," climate scientist Katharine Hayhoe begs to differ.

"What's with all the snow?" she tweeted Tuesday. "Does it mean global warming is finished? Nope; it's exactly the opposite, in fact. Warmer temperatures are increasing the risk of lake-effect snow."

At the end of her twitter thread, Hayhoe joked, "When two feet of snow's just been dumped on our driveway, we all think—I'd like a little global warming now, please!"

Recent studies have shown the effect of climate change on regional precipitation. In a study published earlier this month, researchers from Dartmouth College, the University of Maine and the University of New Hampshire revealed how they were shocked to find that the Alaska Range has received an average of 18 feet of snow per year—that's more than double the average of eight feet per year from 1600-1840.

The likely culprit is none other than climate change. The authors suggested that warmer waters from the tropical Pacific and Indian Oceans caused a strengthening of the "Aleutian Low" pressure system with its northward flow of warm, moist air, driving most of the snowfall increases.
