For only third time since 1948, it’s going to be above freezing at the North Pole in December

Thanks to the same low-pressure system that produced blizzards in New Mexico, tornadoes in Texas and flooding in Missouri, the North Pole will be as much as 50 degrees above the seasonal average high on Wednesday, according to some computer models.

The North Pole is getting a taste of the warm late-December temperatures that have caused such havoc in the United States.

The North Pole is getting a taste of the warm late-December temperatures that have caused such havoc in the United States.

Some estimates put the high temperature at about 40 degrees Fahrenheit, substantially warmer than the usual late-December highs of -10 degrees F.

Above-freezing December temperatures at the North Pole have occurred only three times since 1948, Weather Underground blogger Bob Henson tweeted.

CNN Senior Meteorologist Brandon Miller points out that two strong weather systems — the low-pressure mass that’s moved through the U.S. and northern Europe, and a high-pressure system over Siberia — have helped pull warm air from southern Europe and northern Africa.

“Because of the strength of the two systems, it’s allowing that air to travel farther north than it normally would,” he said.

Air is traveling in a clockwise direction around the high-pressure system and counterclockwise around the low, so the two systems next to each other are pulling air from the same direction like a vacuum, he says.

Neither system is uncommon this time of year, incidentally, but their power — and the result of the combination — is unusual, he adds.

Nevertheless, the North Pole high is strictly a temporary phenomenon, with temperatures returning to normal very soon, says Miller. What’s important to monitor is whether the warming becomes part of a pattern that reduces sea ice in the Arctic — something scientists are watching closely.

“Some climate models predict an ice-free Arctic at least part of the year in the coming decades,” Miller said. “If you’re going to have an ice-free Arctic and you’re going to have big melts in the summertime but also limit ice recovery in the winter, you’re going to have to have events like this happen.”

He continued, “If you have a lot of these events, especially with strong winds that can push that sea ice around and cause some vulnerabilities, if this is a pattern of things to come, it could really become worrisome for the stability of the Arctic.”

Incidentally, if you want to travel to the relative warmth of the North Pole, you may want to bring a lamp. Right now, it’s dark 24 hours a day.
