Arctic warming has given scientists the willies. The freak phenomenon of above-freezing temperatures in the midst of the blacked-out Arctic winter began a few years ago with a brief warm spell or two. This winter, however, Arctic temperatures have averaged 20C above normal.
An alarming heatwave in the sunless winter Arctic is causing blizzards in Europe and forcing scientists to reconsider even their most pessimistic forecasts of climate change.
Although it could yet prove to be a freak event, the primary concern is that global warming is eroding the polar vortex, the powerful winds that once insulated the frozen north.
The north pole gets no sunlight until March, but an influx of warm air has pushed temperatures in Siberia up by as much as 35C above historical averages this month. Greenland has already experienced 61 hours above freezing in 2018 - more than three times as any previous year.
Seasoned observers have described what is happening as “crazy,” “weird,” and “simply shocking”.
“This is an anomaly among anomalies. It is far enough outside the historical range that it is worrying – it is a suggestion that there are further surprises in store as we continue to poke the angry beast that is our climate,” said Michael Mann, director of the Earth System Science Center at Pennsylvania State University. “The Arctic has always been regarded as a bellwether because of the vicious cycles that amplify human-caused warming in that particular region. And it is sending out a clear warning.”
Fortunately, we don't have to worry. Our prime minister is on top of this. What, he's busy with bitumen, pipelines and supertankers? We're screwed?
