North Pole Region Predicted to Experience Another Instance of Above Freezing Temperatures as the Bering Sea Ice is Blasted Away
Those previously rare instances of above freezing temperatures in the Arctic north during winter time are happening more and more often.

Just Monday and Tuesday of this week, Cape Jessup, Greenland — a mere 400 miles away from the North Pole — experienced above freezing temperatures for two days in a row. This following a February 5 warm air invasion that drove above 32 F temperatures to within 150 miles of this furthest northerly point in our Hemisphere even as, by February 20th, a warm air invasion relentlessly melted the Bering Sea’s typically frozen surface (see image above).
Far Above Average Temperatures Over Our Pole
It’s not just a case of warming near the pole itself. It’s the entire Arctic region above the 66 degree North Latitude line. Over the past few days, Arctic temperature anomalies have exceeded 6 degrees Celsius above the 1981 to 2010 baseline. A period that was already showing a serious warming trend.

For reference, 6 C warmer than normal daily readings for any large region of the Earth’s surface is a very serious temperature departure. And the Arctic is clearly feeling it as it suffers the lowest sea ice extent in our record keeping. The heat is meanwhile wreaking out of control harm on the Arctic environment — endangering key species like seals, walrus, puffins, and polar bears, setting off very rapid coastal erosion as storm waves grow taller, triggering far more extensive and powerful Arctic wildfires, and causing mass land subsidence and various harmful environmental feedbacks from permafrost thaw. It’s also causing Greenland’s massive glaciers to melt faster — contributing to an acceleration in the rate of global sea level rise.
The warm air has been invading primarily from the ocean zones in the Atlantic and the Pacific. Warm storms have frequently roared north through the Barents Sea and up the Greenland Strait near Svalbard. Massive blocking high pressure systems have shoved outlandishly warm temperatures through the Bering Sea on the Pacific side day after day, month after month.
Warm Air Invasions Clear Sea Ice During Winter
A recent warm air invasion has practically cleared the Bering Sea of ice. And the ice edge there is further withdrawn than it has ever been in its history. As we can see from the below animation, this crazy and rapid clearing of ice continues to drive further and further north — ushered in by a relentless invasion of warm air — during February. A time when Bering ice should be expanding, not contracting.
What’s causing such extreme polar weather? In two words — climate change. But drilling down, the details can actually get pretty complicated.
During recent winters, human-caused climate change has been driving temperatures into never-before-seen ranges over our northern pole. Increasingly, Sudden Stratospheric Warming events have been propelling warm air into the upper layers of the atmosphere. The Polar Vortex, which during winter relies on a column of sequestered cold air to maintain stability, is blown off-kilter as these upper level layers heat up. This, in turn, has generated extreme wave patterns in the winter Northern Hemisphere Jet Stream — enabling much warmer than usual temperatures to rocket northward.
An Ongoing Series of Warming Events
On December 30 of 2015, and enabled by a high amplitude Jet Stream wave, a powerful warm storm event pushed a strong wedge of warm, above freezing, air all the way across the 90 North Latitude line. Meanwhile, Jessup Greenland hit above freezing for what was likely the first time ever over the past two winters. Last year’s Arctic sea ice hit the lowest levels ever seen during March due to all the extra heat. And the warm temperature extremes appear to be deepening.
Now, as of mid February, a powerful Sudden Stratospheric Warming Event has again blown the Polar Vortex off kilter — weakening it and enabling warm air to flood into the Arctic even as colder air is displaced southward over Canada, the Western U.S. and Europe. Translating to the surface, this train wreck in the upper level winds has driven the extreme polar warming events of the past 8-10 days even as cold air invasions have overtaken Europe and the U.S. East experiences record-breaking heat.
The polar warming event is still ongoing. And it is expected to deliver another blow to an Arctic environment that typically experiences -30 degree Celsius temperatures this time of year. For another major warm wind invasion is forecast to drive above freezing temperatures over the North Pole by this weekend. Strong south to north winds along an extreme ridge in the Jet Stream are predicted to push 1-2 C temperatures (or approximately 55 F above average temps) over the North Pole on Saturday and Sunday.

Though rare during December, above freezing temperatures at the North Pole during February are practically unheard of. The period of February through April should be a time of strengthening and thickening ice ahead of melt season. But during 2018 this appears not to be the case. The ice instead, in key regions, is being delivered with serious setbacks which is greatly retarding this year’s typical Arctic Ocean ice formation.
If this most recent polar warming event emerges as predicted, it will provide yet one more powerful blow to an already greatly weakened Arctic sea ice pack during a time of year when extents and areas should be reaching their peak. And that’s bad news for both the Arctic and global environments.

Major signals of on an ongoing and inexorable global warming trend continued to be apparent during January of 2018, according to NASA records.
The first month of this year saw global temperatures in the range of 0.78 degrees Celsius above NASA’s 20th Century baseline — or about 1 C warmer than 1880s averages when NASA record-keeping began.
Despite the influence of La Nina — which during 2018 is stronger than a similar 2017 Pacific Ocean cooling event — January was the 5th hottest such month in all of the 138 year global climate record. According to NASA, all of the top five hottest Januaries ever recorded have occurred since 2007, with four of those five occurring during the last five years.
(Arctic warming is the primary feature of the fifth hottest January in NASA’s 138 year climate record. Image source: NASA.)
Warm temperature departures for the month were most extreme over the Arctic, over western North America, and through North and Western Europe. This outlier warmth contributed to record low sea ice extent measures in the Arctic and helped to rapidly expand drought conditions across the U.S. In the Southern Hemisphere, Antarctica — recently seeing a series of glacial calving events in the west which hint at a quickening pulse of ice entering the world’s rising oceans — saw an abnormally warm austral summer month. Meanwhile, Australia experienced its own third hottest January even as concerns over renewed mass coral bleaching across the Great Barrier Reef were again on the rise.
During La Nina, movement of warm air and water toward the polar region is enhanced. To this point, global sea ice extent measures are again in record low ranges even after receiving a serious hammering during the winter of 2017. In January, record to near record polar warmth helped to drive a rapid fall in global sea ice extent to today’s record low values in the range of 16 million square kilometers.
Record low sea ice coverage is a climate change amplifier in that it uncovers dark ocean surfaces that capture more of the sun’s rays than white, reflective ice. In addition, open ocean ventilates more heat into the polar atmosphere. Heat that would typically be sequestered beneath the ice. This warming amplification (polar amplification) can also have an impact on the polar circulation of the Jet Stream — causing it to meander more which results in increasing instances of extreme weather (hot, cold, wet, dry, stormy) in the middle latitudes.
Over the coming months, we should expect some continued stress to both Arctic and Antarctic sea ice — with the caveat being that cloudier late springs and early summers have tended to retard warm season ice loss during recent years in the Northern Hemisphere. That said, continued movement into record low ranges for the Arctic hint that rapid advance of melt during winter may eventually translate to summer.
The primary driver of these serious changes to the global environment is continued fossil fuel burning. And with atmospheric CO2 likely to hit between 411 and 412 parts per million this year (with CO2e ranging toward 493 ppm adding in all greenhouse gasses) the amount of warming already being locked in is starting to look quite dangerous in a number respects. That said, damage can still be greatly limited if the world works to rapidly transition toward renewable energy and keeps harmful fuels where they belong — in the ground.

Like most of Elon Musk’s endeavors, Tesla is not a risk adverse venture.
Quite to the contrary, by taking on established energy and automotive players on fields that they’ve dominated for decades socially, politically, and economically, it would seem that Musk and, by extension, Tesla have done everything they can to give risk a big, fat, honking troll.
Helpful Risk of Undertaking Clean Energy Transition vs Risk of Extreme Harms From Climate Change
But if there was ever a time when the serious risk inherent to rapidly breaking new ground in the clean energy field was necessary, then it is now. Just today, in the dead of what should be frigid Arctic winter, a tanker brimming full with climate change amplifying liquified gas (LNG) crossed the typically frozen solid Arctic Ocean. And here’s the kicker — it did it without the need of an escorting ice breaker.
This is the first time a vessel has navigated across the Arctic in such a way during February. Ever. An ominous new marvel made possible by a warming Arctic that is also bringing along such terrors as a multiplying list of endangered species, loss of fisheries, increasing rates of ocean acidification, thawing permafrost, melting glaciers, massive Arctic wildfires, and quickening sea level rise.
In light of such hard facts, we could reasonably say that the risks Tesla and Musk are taking are needed, are indeed necessary if modern society is to have a decent chance at confronting the rising age of human-caused climate change. That the efforts by Tesla and others to speed a transition to energies that do not contribute to the already significant climate harms coming down the pipe are something both valid and necessary. Something that all true industry, education, civil and government leaders would responsibly step up to support.
Of course, the story of clean energy isn’t all about Tesla. It’s about the global need for a swift energy transition away from climate change driving fossil fuels. But Tesla, as the only major U.S. integrated clean energy and transport corporation presently operating that does not also have a stake in fossil fuel infrastructure, is a vision of what energy companies should look like if we are to achieve a more benevolent climate future. And it is for this reason that the company has generated so much support among climate change response and clean energy advocates.
300,000 All-Electric Vehicles Produced
But in order for Tesla to succeed in helping to speed along a necessary clean energy revolution, it needs to produce clean energy systems in increasingly high volumes. During recent days Tesla crossed a major milestone on the path toward mass production of clean energy vehicles. For as of the first half of February, Tesla is reported to have produced its 300,000th electrical vehicle.
A somewhat vague indicator, it nonetheless gives us an idea of the pace at which Tesla EV production is increasing. And, by extension, how fast the more affordable Model 3 is also ramping up.
Consider that approximately 101,000 Teslas were produced during 2017. Also consider that by the end of the year, Tesla had produced about 286,500 EVs throughout its lifetime as a company. If the company crossed the 300,000 mark during early February as indicated, it tells us that Tesla is presently producing around 10,000 EVs per month in total.
This extrapolated pace (keep in mind, we are reading tea leaves here), suggests that Tesla is already building on record 2017 production levels. It also suggests that Model 3 is having a strong impact on the overall rate of production. What’s even more significant is that Tesla production has historically tended to slow down at the start of each quarter and then speed up at the end of each quarter. Right now, overall Tesla production appears to still be on an up ramp.
(Bloomberg has built a model aimed at tracking the total number of Tesla Model 3s produced. It presently estimates that 7,438 Model 3s in total have been built and that Tesla has finally broken the 1,000 vehicle per week threshold consistently. See Bloomberg’s report and interactive graphs here.)
Add to this report the results of a recent Bloomberg model study estimating that around 7,438 Model 3s have been produced in total since July of 2017 and that average weekly production rates are now slightly above 1,000. The Bloomberg study relies on extrapolation from VIN number reporting and observation as well as on internet reports. The reports and data are then plugged into a mathematical model that provides an estimate of total Model 3 production.
The Bloomberg study indicates that Model 3 hit a big surge in production during late January and early February. Which is cautious good news for those still standing in the long line waiting for one of these revolutionary vehicles. A 1,000 Model 3 per week production rate roughly translates to 4,000 per month — which would account for the apparent early year acceleration in total Tesla EV production. But in order to satisfy demand any time soon, Model 3 production will have to increase to more than 5,000 vehicles per week in rather short order.
So Model 3 still has a long way to go before it can start substantially meeting the amazing pent-up demand of the 500,000 person waiting list. In addition, production will have to continue to rapidly pick up if Tesla is to meet the stated goal of 2,500 Model 3s per week by the end of March. That said, Tesla appears to be well on the road toward expanding mass clean energy vehicle production and could more than double its annual EV output this year. Considering the state of the world’s climate, this couldn’t happen sooner.
