Map of the day: Record Arctic heat wave continues


The latest map from WeatherBELL Analytics reveals that a heat wave unlike any ever seen since the recording of systematic data began continues in the far North, reports Ryan Maue, who tweets “January 2017 global temperature anomaly +0.41°C [1981-2010 baseline] Arctic extreme (relative) warmth continues.”

Indeed:

Veteran Arctic climate scientists are stunned.

“[A]fter studying the Arctic and its climate for three and a half decades, I have concluded that what has happened over the last year goes beyond even the extreme,” wrote Mark Serreze, director of the National Snow and Ice Data Center in Boulder, Colo., in an essay for Earth magazine.

At the North Pole, the mercury has rocketed to near the melting point twice since November, and another huge flux of warmth is projected by models next week. Their simulations predict some places in the high Arctic will rise over 50 degrees above normal.

The number of freezing degree days is far lower than any other period on record. Eric Holthaus, a meteorologist and science writer who first posted the chart to Twitter, remarked it illustrated a “stunning lack of freezing power” over the Arctic. “This is happening now,” he added. “Not in 50 or 100 years — now.”

One chart, in particular, is a jaw-dropping and emblematic display of the intensity and duration of the Arctic warmth. It illustrates the difference from normal in the number of “freezing degree days,” a measure of the accumulated cold since September.

Averaged over the Arctic north of 80 degrees, this chart displays the difference from normal in the cumulative number of freezing degree days September to January. Freezing degree days accumulate according to the number of degrees Celsius below freezing. Minus-5 Celsius would represent five freezing degree days.

The winter has seen fewer days of sub-freezing temperatures than ever before recorded, reports meteorologist and science writer Eric Holthaus, who tweeted  the chart , noting :

The Arctic’s stunning lack of freezing power has already beat the record set last *June*. This is happening now. Not in 50 or 100 years—now.

Here’s the chart:

Looks like life under Trump is going to be hell on earth.

Literally.

  1. Don’t expect this trend to change or for more people to care. We in the US have become the anti-science country. Thanks for the post.
