Polar Heatwave Digs in as Arctic Sea Ice Crashes — Blue Ocean Event Looking More and More Likely

We’ve never seen May heat like what’s being predicted in the Arctic over the next seven days. A shot of warm airs blowing northward over Siberia that are expected to generate a warm front that takes in nearly the entire Arctic Ocean. A weather pattern that, if it emerges, will completely compromise the central region of polar cold that has traditionally driven Northern Hemisphere weather patterns.


This week, a huge pulse of warm air rose up over Northwest Canada and Alaska. Invading the Beaufort, it drove a broad warm front which forced near or above freezing temperatures over between 1/4 to 1/3 of the Arctic Ocean zone. Regions from the East Siberian Sea, through the Chukchi, into the Beaufort, and including a chunk of the polar zone above the 80th parallel all experienced these anomalously warm readings. By Friday, air temperature anomalies in the entire Arctic zone above 66 North were about 3 C above average and in a large section of the hot zone centered on the Beaufort temperatures ranged between 10-15 C above average. For the Arctic, it appeared that June had arrived a month early.

Arctic sea ice May 12 2016

(Abundant Arctic snow and sea ice melt on May 12 provides a visible record of a region compromised by the heat of human-forced climate change. Large land regions — such as Northwest Canada and Alaska — snow free when they should not be. And larger regions of open water appear in the zones that were traditionally covered by sea ice. A bluing over the Chukchi and Beaufort is also indicative of melt pond proliferation. Summer, it appears, has come to the Arctic far too early. Image source: LANCE-MODIS.)

The effect of all this heat — just the latest hot flare during a record warm 2016 — on the sea ice has been tremendous. Huge areas of dark, ice-free water have opened up. The Bering is practically ice free. The Chukchi is plagued with thin ice, large polynyas, and melt ponds. Baffin Bay and the Barents are greatly reduced. And in the Beaufort a massive 120 to 200 mile wide region of open water continues to expand.

For Arctic Sea Ice Melt, Mid Summer is Happening in May

Pretty much all the major monitors now show Arctic sea ice plummeting deep into record low ranges. The JAXA extent measure yesterday rocketed past the 11.5 million square kilometer mark with barely a blink following multiple days of 100,000 square kilometer losses. DMI looks like the bottom dropped out of its own extent and volume measures. And NSIDC shows Arctic sea ice extent levels widening the gap from previous record lows for this time of year.

Arctic sea ice extent jaxa

(2016 Actic sea ice — indicated by the red line in the JAXA monitor above — continues its record plunge. Record Arctic heat during 2016 has driven a never-before-seen rate of melt for the first four and a half months of this year. If such melt rates continue, there will be very little sea ice left by melt season end in September. Image source: JAXA.)

Overall, not only is the sea ice less extensive and thinner than it has ever been for this time of year, but the rates of loss it is now experiencing are more similar to those that would typically be seen during June and July — not May. In such a context of record heat and melt, current new sea ice extent lows are about 9-10 days ahead of the previous record low, 22-24 days ahead of the 2000s average line, more than a month ahead of the 1990s average line, and fully a month and a half ahead of the 1980s average line. In other words, there is something seriously, seriously wrong with the polar region of our world.

Freakish Warm Front To Cross From Siberia to the Barents

As bad as the current situation is, the coming week looks like it’s setting up to be far worse. A second massive polar warm front is in the process of bulging northward from the region of Eastern Siberia near the East Siberian Sea. This warm front — driven on by an anomalous ridge in the Jet Stream and backed by warm winds flooding up from the East Asian heatwave and wildfire zone — is predicted to bow outward over the coming five days. It is expected to encompass all of the East Siberian Sea and the Laptev, traverse the 80th parallel, continue on past the North Pole, and then flood out into the Barents. Essentially, it’s a warm front that will cross the polar zone in total — completely ignoring the laws of Jet Stream dynamics and basically rupturing what is traditionally an area of cold centering on the Pole.


(Warm winds are predicted to be pulled up from Siberia as a high pressure system churns over the Beaufort and a warm front crosses the North Pole — flushing below freezing temperature out of a majority of the Arctic Ocean Basin on May 16th in the GFS model forecast. Note the very large extent of predicted above freezing temperatures in the graphic above. Image source: Earth Nullschool.)

In four years of unbroken Arctic observation and threat analysis related to human-caused climate change, I’ve never seen anything like this. And given the odd effects of fossil fuel emissions-forced climate change, I’ve definitely observed some pretty weird stuff. To say this really kinda takes the cake for Arctic weirdness would be an understatement.

Never-Before Seen Conditions Consistent With Human-Forced Climate Change

By May 20, most of the Arctic Ocean is predicted to see near-freezing or above-freezing temperatures. Readings warm enough to promote surface melt of the ice pretty much everywhere and across all basins. Readings that for the entire Arctic region above 66 North are predicted to be 5 C above average. That is one hell of an anomaly. Something that would be odd if we saw it during January (when climate change related seasonal warming has typically taken greater hold). But for May this is absolutely outlandishly hot.

May 20 Crazy Polar anomaly

(Temperatures in the Arctic are expected to hit a +5.04 C anomaly by May 20. Such an amazing amount of heat will generate rapid thaw conditions that were typically only experienced in the middle of summer during previous record warm years. Image source: Climate Reanalyzer.)

These are conditions that even during the previously record warm period of the 2000s normally didn’t take come into play until late June or early July. Conditions that were practically unheard of for any single day at the peak of summer warmth during the 1980s. Conditions now predicted to happen in late May.

This is climate change, folks. Pure and simple. And if such a pattern of extreme heat continues, it may wipe out practically all the ice by the end of this melt season. This week, it looks like that dreaded event will grow still more likely if this predicted insane heat break-out into the Arctic emerges. An event many scientists thought wouldn’t be possible until the 2070s or 2080s as little as ten years ago. A Blue Ocean Event that is now a very real risk for 2016.

Arctic Sea Ice is Falling off a Cliff and it May Not Survive The Summer

Near zero sea ice by the end of melt season. The dreaded Blue Ocean Event. Something that appears more and more likely to happen during 2016 with each passing day.

These are the kinds of climate-wrecking phase changes in the Arctic people have been worrying about since sea ice extent, area, and volume achieved gut-wrenching plunges during 2007 and 2012. Plunges that were far faster than sea ice melt rates predicted by model runs and by the then scientific consensus on how the Arctic Ocean ice would respond to human-forced warming this Century. For back during the first decade of the the 21st Century the mainstream scientific view was that Arctic sea ice would be about in the range that it is today by around 2070 or 2080. And that we wouldn’t be contemplating the possibility of zero or near zero sea ice until the end of this Century.

But the amazing ability of an unconscionable fossil fuel emission to rapidly transform our world for the worst appears now to outweigh that cautious science. For during 2016, the Arctic is experiencing a record warm year like never before. Average temperatures over the region have been hitting unprecedented ranges. Temperatures that — when one who understands the sensitive nature of the Arctic looks at them — inspires feelings of dislocation and disbelief. For our Arctic sea ice coverage has been consistently in record low ranges throughout Winter, it has been following a steepening curve of loss since April, and it now appears to have started to fall off a cliff. Severe losses that are likely to both impact the Jet Stream and extreme weather formation in the Northern Hemisphere throughout the Spring and Summer of 2016.

Melting more than Two Weeks Faster than the Early 2000s

Since April 27th, according to a record of sea ice extent provided by JAXA, daily rates of sea ice loss have been in the range of 75,000 square kilometers for every 24 hour period. That’s 300,000 square kilometers of sea ice, or an area the size of New Mexico, lost in just four days. Only during 2015 have we ever seen such similarly rapid rates of loss for this time of year.

Sea Ice Rates of Loss Steepening

(We’ve never seen early season sea ice losses like this before. Severe sea ice losses of this variety can help to generate strong ridges and extreme heatwaves like the one we now see affecting India and Southeast Asia. Image source: JAXA.)

However, this excessive rate of loss is occurring across an Arctic region that features dramatically less ice (exceeding the 2015 mark for the same day by about 360,000 square kilometers) than any other comparable year for the same day. In essence, extent melt is now more than a week ahead of any other previous year. It is two and half weeks ahead of melt rates during the 2000s. And this year’s rate of decline is steepening.

Current melt rates, if maintained throughout summer, would wipe out practically all the ice. And, worryingly, this is a distinct possibility given the severely weakened state of the ice, the large areas of dark, open water available to absorb the sun’s rays as Summer progresses, and given the fact that Arctic heat is continuing in extreme record warm ranges. Furthermore, melt rates tend to seasonally steepen starting by mid June. So rapidly ramping rates of loss seen now, at the end of April and through to the start of May, may see further acceleration as more and more direct sunlight keeps falling on already large exposed areas of dark, heat-absorbing water.

Huge Holes in the Beaufort

All throughout the Arctic Basin, these sunlight-absorbing regions take up far more area than is typical. The Bering has melted very early. Baffin Bay is greatly withdrawn from typical years. Hudson Bay is starting to break up. The Barents and Greenland seas feature far more open water than is typical. However, there is no region showing more dramatic early season losses than the Beaufort.

Beaufort rapid melt 2016

(This Beaufort sea has never looked so bad off so early in the year. High amplitude waves in the Jet Stream continue to deliver record warmth, warm, wet winds, and record sea ice melt to this region of the Arctic. For reference, bottom of frame in this image is around 600 miles. The wispy threads you see in the image is cloud cover, the sections of solid white are snow and ice. And the blue you see is the open waters of the Arctic Ocean. Open water gap size in the widest sections is now more than 150 miles. Image source: LANCE-MODIS.)

There, ice continues to rapidly recede away from the Arctic Ocean shores of the Mackenzie Delta and the Canadian Archipelago — where a large gap has opened up in the sea ice. Now ranging from 70-150 miles in width, this area of open water consistently sees surface temperatures warm enough to melt sea ice (above 28 F or about -2 C).

This great body of open water the size of a sea in itself has now created a new early season edge zone for the ice. A place where a kind of mini-dipole can emerge between the more rapidly warming water surfaces and the cooler, reflective ice. Such a zone will tend to be a magnet for storms. And a low pressure system is expected to ride up an extreme bulge in the Jet Stream over Alaska and Canada and on into this Arctic zone over the next few days. Storms of this kind tend to hasten melt and break up of ice in the edge zones by generating waves, by pulling in warmer airs from the south, or by dropping liquid precipitation along the melting ice edge. And the fact that this kind of dynamic is setting up in the Beaufort in early May is nothing short of extraordinary.

Arctic Heat Like We’ve Never Seen Before

Further to the north, high pressure is expected to continue to dominate over the next seven days. This will generate further compaction of the already weak ice even as it allows more and more sunlight to fall over that greatly thinned white veil.

Freezing Degree Days Cross -1000 threshold

(The Arctic is now so warm that this graph is now too small to capture the excession of extreme heat in the region. Freezing degree days are now more than 1,000 less than during a typical year and the already much warmer than normal 1980 to 2000 period. Image source: CIRES.)

Temperatures for the Arctic are expected to range between 2.5 and 3.5 C above average over the next seven days. Very warm conditions that will continue to hammer freezing degree day totals that have now exceeded an unprecedented -1000 since the start of the year in the High Arctic region above the 80 degree North Latitude Line. In layman’s terms, the less freezing degree days the Arctic experiences, the closer it is to melting. And losing 1000 freezing degree days is like removing the coldest month of Winter entirely from the heat balance equation in this highest Latitude region of the Northern Hemisphere.

From just about every indicator, we find that the Arctic sea ice is being hit by heat like never before. And the disturbing precipitous early season losses we now see in combination with the excessive, extreme warmth and melt accelerating weather patterns are likely to continue to reinforce a trend of record losses. Such low sea ice measures will also tend to wrench weather patterns around the globe — providing zones for extreme heatwaves and droughts along the ridge lines and related warm wind invasions of the Arctic that will tend to develop all while generating risk of record precipitation events in the trough zones. To this point, the North American West is again setting up for just such a zonal heatwave pattern. Extreme heat building up in India and Southeast Asia also appears to be following a similar northward advance.

Record Global Heat — Huge Springtime Arctic Warm-up to Crush Sea Ice, Drive Extreme Jet Stream Dip into Europe

We know now, as soon as the middle of April, that 2016 will be the hottest year on record. That not only will it be the hottest year, but that it will crush any other previous record hot year by a wide margin.

NASA GISS head — Gavin Schmidt — in a recent tweet estimated that 2016 would fall into a range near 1.32 C above the 1880-1899 average that NASA uses for its preindustrial baseline. By comparison, 2015 — which was the most recent hottest year on record after 2014 (three in a row!) — hit 1.07 C above the 1880-1899 average.

GISS Temperature Map First Quarter of 2016

(According to NASA, the first three months of 2016 were 1.25 C above the NASA 20th Century baseline and a ridiculous 1.47 C above the 1880 through 1899 preindustrial average. Image source: NASA GISS.)

As a result, 2016 will likely have jumped by about a quarter of a degree Celsius in a single year. If every year from 2016 on warmed up so fast the world would surpass the dreaded 2 C mark by 2019 and rocket to about +22 C above 19th Century averages by 2100. That’s not going to happen. Why? Because natural variability assisted greenhouse gas warming from fossil fuels to kick 2016 higher in the form of a serious heavyweight El Nino. But it’s a decent exercise to show how ridiculously fast the world is expected to warm from 2015 to 2016. And in the 2014-2016 string of three record warm years in a row we are basically expecting a 0.40 C jump above the then record warm year of 2010. Given that the world has warmed, on average by about 0.15 C to 0.20 C per decade since the late 1970s, what we’re expecting to see is about two decades worth of warming all cram-jammed into the past three years.

More Severe Arctic Heat is on the Way

But the Earth, as of this Earth Day, hasn’t warmed evenly. A far, far greater portion of that excess heat has stooped over the Arctic. During the first three months of 2016, the Arctic region above 66 degrees North Latitude has been fully 4.5 C hotter than the NASA 20th Century baseline. That’s a departure more than three times that of the rest of the Earth. And that’s bad news for anyone concerned about sea ice, or polar bears, or Arctic carbon feedbacks, or predictable seasons, or extreme droughts and floods, or the Jet Stream, or Greenland melt, or sea level rise, or … well, you get the picture.

One region, at the boundary between the Arctic Ocean and the Greenland Sea near Svalbard, has been particularly warm. So warm, in fact, that sea surfaces now devour slabs of Arctic Ocean ice blown into it by winds running out of the Arctic in a matter of days. It takes a lot of ocean warmth to have this kind of effect on sea ice. A particularly ferocious amount of heat for the ocean to exhibit so early on in the melt season.

Ice Devoured by Warm Greenland Sea

(Neven posted this excellent blog tracking a ferocious amount of heat in the region of the Greenland and Barents Sea. Arctic Sea Ice Forum commenter Andreas T provided this graphical representation of sea ice disintegration as it was blown into waters just to the north of Svalbard earlier this week.)

Perhaps the easiest way to illustrate how relatively hot the Arctic is now is the fact that sea ice in the region is melting fast. So fast that current extent measures by JAXA are at their lowest levels on record. It’s a precipitous rate of melt that’s about one week ahead of any of the previous fastest melt season. Or you could just look at the number of Arctic freezing degree days recorded at CIRES and find one more measure added to NASA or record low sea ice pointing toward the obvious fact that this year, for the Arctic, has been one of just absolutely ludicrous warmth.

As Winter progresses into Spring, temperatures typically moderate — closing in on baseline averages. And this year has been no exception. However, readings for the entire Arctic have tended to range between 1.5 and 2.5 C above average over the past two weeks. These are some seriously hot departures for Spring. Enough to keep Arctic heat in record ranges for 2016.

Three Powerful Warm Wind Events to Strike the Arctic in Concert

But over the coming five days, a series of south-to-north warm wind events is expected to push even these seasonally excessive readings higher.

Extreme Springtime warming in the Arctic

(GFS model forecasts predict Arctic temperatures to rise into a range between 3 and 5 C above normal for this time of year over the coming week. Such departures are in record ranges and will likely result in rapid snow and sea ice melt even as it drives a wedge of cold air out of the Arctic and over Europe — setting up a high risk of very severe weather events. Image source: Climate Reanalyzer.)

The first event is predicted to originate over the Yamal Peninsula of Russia during Saturday and Sunday — lasting on into Monday and Tuesday. There, temperatures are expected to rise into the (scorching for the Arctic at this time of year) mid 30s (F) as strong, warm winds blow over about 1,000 miles of western Russia and on up into the Kara and Laptev seas which are predicted to, likewise, experience near or above freezing temperatures. Over the entire region, temperatures are expected to range between 18 and 36 degrees F (10-20 C) above typical daily averages for this time of year. Snow and sea ice melt melt rates in this already rapidly thawing region will almost certainly pick up pace in the face of these obnoxiously unseasonable readings.

A second warm wind event is predicted to heat up Greenland, Baffin Bay, the mouth of Hudson Bay and a chunk of the Canadian Archipelago on Monday and Tuesday. A 1,500 mile synoptic southeast to northwest air flow is expected to originate in the Central North Atlantic. Running along the back of a high pressure system rooted between Iceland and Southeastern Greenland, these winds will ram a broad front of above-freezing airs over a rapidly melting Baffin Bay, dramatically warm the southern 2/3 of Greenland, and flush a comparable warm air pulse into the outlets of Hudson Bay. Temperatures in this broad zone are also expected to hit 18-36 F (10-20 C) above average readings. And its effects will likely be strong enough to initiate another strong early season melt spike for Greenland in addition to aiding in driving a quickening pace of melt for Baffin and Hudson bays.

Shattered Ice Beaufort and Chukchi

(Shattered sea ice over the Beaufort and Chukchi looks as if it’s been fractured from a blow from Thor’s mythical hammer Mjolnir. Open water and very thin ice openings stretch as wide as 60 miles in some sections. A warm wind event later this week is expected to provide still more melt pressure to this already greatly weakened sea ice. Image source: LANCE MODIS.)

A final warm wind event will be fed by a big warm up across Alaska predicted to settle in on Wednesday and Thursday. There, temperatures in Central Alaska are expected to rise into the lower 60s as two stalled out lows to the south pull warmer airs up from the Pacific Ocean. This heat is expected to invade the Chukchi and Beaufort seas driving temperatures to near or above freezing over Arctic Ocean surfaces that have already witnessed a great shattering of ice and an opening of dark, heat-venting open water holes. There the anomaly spike will be slightly milder — in the range of 15-32 F (8-18 C) above average. Such heat will provide melt stress to the fractured Beaufort, likely making more permanent the wide array of open water and thin ice spaces as the push toward Summer advances.

Mangled Jet Stream to Bring Storms to Europe

As all this heat bullies its way into the Arctic, a flood of cold air is expected to flee out of the region and on down a big dip in the Jet Stream — making a late-season invasion across the North Atlantic and into Europe. There, as we’ve seen previously during recent warm wind invasions of the Arctic during Fall, Winter and Spring, warm air from the south tends to cause cold to break out and then to dive down the trough lines. And there’s a huge trough predicted to dig in over Europe.

We should expect some rather severe weather to accompany this Springtime onrush of colder air — including potentially extreme thunderstorms, flooding, and even instances of late April snowfall over parts of Norway, Sweden, Scotland, the Alps, and sections of Germany.

Deep Trough Predicted for Europe

(A very deep Arctic trough is expected to dig into Europe and the Mediterranean this coming week bringing with it the likelihood of some very severe weather. Image source: ECMWF/Severe Weather EU.)

Likely increased rates of sea ice melt, a severe blow to record low snow packs around the Arctic and a likely freakish cold air and severe weather invasion of Europe are all a result of this extreme Arctic heat playing havoc with typical weather and seasonality. By the middle of next week, temperature anomalies for the entire Arctic may rise to as high as 5 C above the already much warmer than normal 1981 to 2010 average. In such a case, we could hardly expect weather or climate conditions to be normal and there appears to be a big helping of weirdness and extreme effects coming down the pipe over the next seven days.

Arctic Sea Ice Conditions Worsen, Nightmare Melt Scenario in the Works?

It’s the end of a bad week in a bad month in a bad season in the all-too-bad, human-heated, era for Arctic sea ice. As of the middle of this week, both the US measure — NSIDC — and Japan’s measure — JAXA — were showing record low daily sea ice extents. The lowest levels in the history of Arctic sea ice observation for this time of year and likely the lowest levels for hundreds, even thousands of years.

As charts go, the JAXA graphic looks pretty amazingly ominous. A 2015 sea ice extent line diving below all others, steadily plumbing an abyss that, if not this year or the next, could lead to a dreaded blue ocean event in the not-too-distant future. The kind of upshot from human greenhouse gas emissions we thought we might see by 2080 or later. One that has become increasingly more likely during recent years and that some researchers are expecting could emerge by before 2020.

Sea ice extent

(JAXA sea ice measure plunging to new record lows on May 22 and now hitting a very steep angle of decline. Image source: JAXA Polar Research.)

Above you can seen the 2015 red line taking its most recent plunge after hovering very near to record low levels. According to JAXA’s Polar Research Center, sea ice extent dropped like a stone to 11.44 million square kilometers yesterday, or about 200,000 square kilometers lower than the previous record low value set in 2006.

Divergence in May

The problem is not just one of a new record low. It’s one of timing and divergence. Accelerated melt in the May-to-June time-frame can have serious impacts on late season ice. The reason is that greatly reduced ice coverage also reduces albedo or reflectivity. The result can be compounded warming and increased heat absorption by darker surfaces under the 24 hour Arctic sunlight of June and July.

Large open stretches of ocean also enable swell formation, which can chew away the ice. And already we can see very large sections of dark, low albedo, ocean forming throughout many vulnerable regions.

Arctic ice visual May 22

(MODIS satellite shot shows widespread regions of open ocean and far northward melt advance for this time of year. Image source: LANCE-MODIS.)

For this time of year, we have very advanced sea ice loss and open ocean development in the regions of the Chukchi, the Beaufort, Northern Baffin Bay and the Kara. In addition, large open water areas are now becoming visible in the Laptev. A far northern extent of sea ice melt for May in addition to typical seasonal losses coming from Hudson Bay and southern Baffin Bay.

Such record low ice totals at this time of year can enable far greater melt advance by end season if the weather stacks up in all the wrong ways. And, at least for the next week, the weather forecast is tilting ever more heavily toward a melt-enhancing extreme warming of Arctic regions.

Arctic Warm Air Invasion Forecast to Continue

Over the next seven days, heat is predicted to continue to flood from south to north — goaded along by high amplitude ridges in the Jet Stream continuing to form over Northwestern North America and the Siberian region adjacent to the Kara Sea. The warm flux zones are forecast to deliver unseasonable, above average temperatures to the Arctic — resulting a general state of much warmer than normal conditions for the entire Arctic Ocean by late next week.

Air Temperature Anomaly ArcticAir Temperature Arctic May 29

(Side-by-side comparison of Arctic temperature anomaly forecast [left] and 2 meter temperature forecast [right] for May 29, 2015 in the GFS model run as provided and graphically displayed by Climate Reanalyzer. It’s worth noting that such extreme anomalies are very unusual for Arctic Ocean regions during late spring and summer.)

As a result, we see temperature anomalies for the entire Arctic Ocean zone hitting a range of between 5 and 15 degrees Celsius above average for next Friday (May 29, 2015). Such a warm air surge would push temperatures in the above freezing range for almost the entire Arctic Ocean area. These are temperatures more typical of late June and early July. Conditions that, should they emerge, would result in a multiplication of ice-threatening melt ponds, a further expansion and warming of already unseasonably large open water zones, and a forcing of more ice-eating, high heat content water vapor into the Arctic environment.

Any forecast is subject to uncertainty. Rapid May melt during 2013 and 2014 stalled out during June of those years. However, May melt is significantly more advanced this year than during those years. And, as opposed to 2013 and 2014, GFS model forecasts showing warmer than normal conditions have tended to be correct. The warm air slots over Northwest North American and Western Siberia are also very well established at this time.

Melt Ponds Barrow May 22

(Snow cover gone, melt ponds plainly visible at Barrow Alaska today. Proliferation of melt ponds during May and June can greatly enhance risk of record low totals come August and September. Image source: Barrow Sea Ice Cam.)

As a result, there’s high risk that the current record lows now appearing in the NSIDC and JAXA measures with continue to deepen over the coming week. It’s an utterly wretched situation for sea ice in the Northern Hemisphere. One that will bear very close watching as the risks now appear to be heading toward some unsettling markers.
