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.

First off: Bangkok Wakes to Rain, the intricately wrought, elegantly crafted debut novel by the Thai-American author Pitchaya Sudbanthad, isn't really about climate change. This tale set in the sprawling subtropical Thai capital is ultimately a kind of family saga — although its interconnected characters aren't necessarily linked by a bloodline. What binds them is their relationship to a small parcel of urban land on which has variously stood a Christian mission, an upper-class family house, and a towering condominium. All of the characters have either called this place home or had some other significant connection to it.
Maine Gov. Janet Mills signed a bill into law Thursday banning public schools or universities in the state from using Native American mascots, names or imagery. Mills' action will make Maine the first state in the nation with such a ban once it goes into effect later this year, The Bangor Daily News reported.
Inslee's 'Evergreen Economy Plan' Calls for $9 Trillion Investment in New Green Jobs, Would Help Fossil Fuel Workers Transition

A new climate action plan put forth by Democratic presidential candidate Gov. Jay Inslee on Thursday is being praised for highlighting the enormous benefits that would result from a rapid shift in the U.S. to a renewable energy economy that centers on the needs of workers and vulnerable communities.
