No matter what this winter holds in store, someone, somewhere, will blame it on global warming.
Recall that the last two snowy and cold winters in the eastern U.S. were blamed, by some, on greater than normal snowfall amounts across Eurasia during the preceding fall season. And the snowy Eurasian autumns were blamed on the low levels of Arctic sea ice during September—which of course was blamed on anthropogenic global warming. Forecaster Judah Cohen explained how this works in a Christmas day op-ed in the New York Times last year—published the day before a nearly 2 foot snowstorm buried the city:
“As global temperatures have warmed and as Arctic sea ice has melted over the past two and a half decades, more moisture has become available to fall as snow over the continents. So the snow cover across Siberia in the fall has steadily increased. … It’s all a snow job by nature. The reality is, we’re freezing not in spite of climate change but because of it.”
And back in January of 2000, during a particularly mild winter in New York City, the Times ran an article which blamed the mild, snowless weather on global warming:
“I bought a sled in ’96 for my daughter,” said Dr. Michael Oppenheimer, a scientist at the nonprofit Environmental Defense Fund. ”It’s been sitting in the stairwell, and hasn’t been used. I used to go sledding all the time. It’s one of my most vivid and pleasant memories as a kid, hauling the sled out to Cunningham Park in Queens.”
…Dr. Oppenheimer, among other ecologists, points to global warming as perhaps the most significant long-term factor.
But such is the cycle of the daily news. Anything unusual has to have a cause, and global warming has gone from being the cause du jour, to being the cause de rigueur. So you don’t have usually to look very far to find someone fingering global warming for anything meteorological—especially when it can be spun in a negative context.
So, what kind of global warming linkages should we expect from this year’s winter?
