Does Record Snowfall Disprove Global Warming? 'Exactly the Opposite,' Scientist Says
The 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.
"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."
According to the National Weather Service, "Lake Effect snow occurs when cold air, often originating from Canada, moves across the open waters of the Great Lakes. As the cold air passes over the unfrozen and relatively warm waters of the Great Lakes, warmth and moisture are transferred into the lowest portion of the atmosphere. The air rises, clouds form and grow into narrow band that produces 2 to 3 inches of snow per hour or more."
Hayhoe went on to explain over several tweets that both natural cycles (i.e. the North Atlantic Oscillation, La Niña) and human factors (i.e. rising temperatures from man-made climate change) have exacerbated this weather phenomenon.
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.

Far-reaching allegations about how a climate-sinning American multinational could shamelessly lie to the public about its wrongdoing mobilized a small group of New York students on a cold November morning. They stood in front of New York's Supreme Court last week to follow the unprecedented lawsuit against ExxonMobil.

Leah Garcés used to hate poultry farmers.
The animal rights activist, who opposes factory farming, had an adversarial relationship with chicken farmers until around five years ago, when she sat down to listen to one. She met a poultry farmer called Craig Watts in rural North Carolina and learned that the problems stemming from factory farming extended beyond animal cruelty.
Temperatures plunged rapidly across the U.S. this week and around 70 percent of the population is expected to experience temperatures around freezing Wednesday.
