But for those of us living here, it’s not a pretty picture. We are being devastated by a slow-motion natural disaster of historic proportions. The disaster is eerily quiet. There are no floating bodies or vistas of destroyed homes. But there’s no denying that this is a catastrophe.
In just three weeks, between Jan. 27 and Feb. 15, we have had four epic blizzards — seven feet of precipitation over three weeks — which crushed roofs, burst gutters, destroyed roads and sidewalks, closed schools and businesses, shut down highways, crippled public transit and trapped people in their homes. The infamous Blizzard of 1978 brought around 27 inches of snow and shut down the region for a week. In less than a month, we’ve seen more than three times as much snow. The temperature has hovered between 5 and 25 degrees, so the snow and ice haven’t melted.E.J. Graff
But surely this means global warming is a myth! – you say.
Wrong, many models predict this precise consequence of global warming, caused by several mechanisms. In fact, this ‘blizzard from hell’ scenario was the subject of a SF novel by Kim Stanley Robinson, Fifty Degrees Below, and the current situation looks pretty damn similar to how the author imagined it 10 years ago.
What does that have to do with climate change? Sea ice is vanishing from the Arctic thanks to climate change, which leaves behind dark open ocean water, which absorbs more of the heat from the sun than reflective ice. That in turn is helping to cause the Arctic to warm faster than the rest of the planet, almost twice the global average. The jet stream—the belt of fast-flowing, westerly winds that essentially serves as the boundary between cold northern air and warmer southern air—is driven by temperature difference between the northerly latitudes and the tropical ones. Some scientists theorize that as that temperature difference narrows, it may weaken the jet stream, which in turns makes it more likely that cold Arctic air will escape the polar vortex and flow southward. Right now, an unusually large kink in the jet stream has that Arctic air flowing much further south than it usually would.Bryan Walsh
