Journal Nature Refutes PIK’s Fantasy-Rich Science That A Warmer Arctic Causes Extreme Cold Snaps

Reposted From the NoTricksZone

By P Gosselin on 9. February 2021

The polar vortex theory takes a beating: The claim a warm Arctic is behind the brutally cold winter conditions at the mid latitudes is shown by a Nature study to be scientifically baseless. 

Hat-tip: Die kalte Sonne.

Now that Europe and North America are getting blasted by unusually severe winter weather, which climate alarmists predicted 20 years ago would be a thing of the past, the alarmists are desperate to find an explanation to escape embarrassment.

PIK science suggests warmth begets cold

They’ve come up with the polar vortex explanation: the bitter cold we are now experiencing at the middle latitudes is in fact due to the warmer Arctic, they say. And this wreaks havoc on the jet stream which in turn results in cold Arctic blasts dipping deep into the middle latitudes. Yes, cold winters are in fact exactly what we should expect in a rapidly warming world!

Levermann and Rahmstorf

For example the two media front men Anders Levermann and Stefan Rahmstorf of the Potsdam Climate Institute (PIK) have been telling this to the ever gullible German media outlets, like Bild and Spiegel. Yet, many suspect it’s scientific fraud designed to fool the public and to hide the fact that their global warming predictions are in reality glaring failures.

Journal Nature refutes fantasy-rich PIK explanation

For example a recent paper appearing in Nature titled “Weakened evidence for mid-latitude impacts of Arctic warming“, authored by Blackport et al, refutes this highly fantasy-rich hypothesis pitched by the two PIK scientists.

The Nature article writes:

Jennifer Francis, whose seminal work proposed that Arctic warming was leading to a wavier jet stream, predicted in 2014 that “within a few years, as Arctic amplification continues, we will have enough data to know whether or not we’re right”6.

So, six years on, what has changed? Arctic amplification and sea-ice loss have indeed continued (Fig. 1). But predictions of a more negative Arctic Oscillation, wavier jet stream, colder winters in mid-latitudes or, more specifically, in Eurasia, and more frequent and/or widespread cold extremes have not become reality (Fig. 1).

Cold waves have been decreasing

Other experts have also noticed what PIK is doing here. Dr. Roy Spencer wrote at his blog in 2019 that U.S. cold waves have been decreasing, thus contradicting the PIK:

Source: Dr. Roy Spencer.

“The trend is markedly downward in the most recent 40 years (since 1979) which is the earliest we have reliable measurements of Arctic sea ice from satellite microwave radiometers (my specialty),” Spencer noted.

“Made to fit where they don’t fit”

Also on Rahmstorf’s claim Arctic warmth begets extreme cold, Swiss veteran meteorologist Jörg Kachelmann tweeted directly:

You never know which is more terrible and unscrupulous, all the right-wing nuts who see a winter weather situation as an argument against the climate crisis or the desperately unscientific @rahmstorf who now also attributes an ordinary winter weather situation to climate change,”

On the Rahmstorf’s approach, Kachelmann adds:

No, there’s hardly any science in the story.

Things are being made to fit where they don’t fit. As always.”

Der Spiegel’s “rubbish”

Unfortunately, the polar vortex tale has been effective at duping the gullible media journalists, like those at Der Spiegel. They too are trying to hide their embarrassment of having been suckered by the manmade global warming catastrophe hoax over the past 3 decades. tweets further:

The polar vortex is doing very well.

But because hardly anyone will verify this, because no one knows what it is and what it should look like, @derspiegel throws
throws the principles of editorial control overboard and writes rubbish.”

But don’t expect the media to concede they’ve been duped any time soon. It’s like one famous scientist once said: “Science progresses one funeral at a time.”

It’s going to take awhile longer.

Without this fake “climate crisis” the Great Reset of Prince Charles et-al would go belly up. And that was openly discussed at Davos, Switzerland.

The acutely disastrous financial crisis, which the good Prince would like to avert by writing off 80% of the human population, does in fact need an immediate solution which the good Prince might not like at all – Glass-Steagall bank separation as FDR did in the 1930’s.

It is high time for so-called weather experts, (weathermen?) to actually look at the real world.

Glass-Steagall was pre-FDR, as it was written and debated during 1932. It had become utterly outmoded by the 1990s, and was the source of most commercial banks tettering on the edge of insolvancy because it had closed off sources of business income, but allowed all sorts of new, and competing, modes of banking.

Sure Senators Glass and Steagall wrote it up. FDR made it law. Clinton dumped it under pressure of impeachment – Lewinsky-gate.
Since then it has been crash after crash. The bailouts have destroyed the US – healthcare is a wreck. So we have lock-downs to avoid mentioning the bailouts, which ironically will crash what´s left.
So we need Glass-Steagall to make it crystal clear – no bailout.
Anyway any attempt to bailout now is impossible, so they think the Great Reset with a world digital currency (Zuck´s bucks – remember Libra/) will work – it simply cannot.

The jets have been getting wavier since about 2000 but it takes a while for the consequent cooling to become apparent. The past 40 years may have seen less US cold waves but they are coming back now and it is nothing to do with radiative gases.

At times of quiet sun there are more sudden stratospheric warmings, more La Ninas, more clouds and a cooling Earth.

She says this:

So she is suggesting a local West European effect rather than global so as to stop anyone thinking that the solar effect is global. It was a damage limitation paper after the record cold of the UK in December 2010 which was the coldest in 100 years.

It’s currently -46 F in Proudhon Bay, AK, far below normal for mid-February, or anytime there. So it appears the hypothetical Arctic warmth to produce mid-latitude chill is missing. Maybe it’s hiding in the Arctic Ocean. Except that sea ice is presently above average for this date in the past decade.

PARIS (AP) — Workers at the Eiffel Tower used a blowtorch to melt the ice collecting on its surfaces and snow was blocking roads and halting trains and school buses Wednesday across northern France.
Amid a European cold snap, areas in Normandy and Brittany unused to such icy conditions were closing highways for lack of snow-clearing equipment. In parts of the Paris region, local authorities halted school buses and urged parents to keep their children at home.
Snow blanketed the French capital and froze the Eiffel Tower.

Reply to  Robert W Turner
February 10, 2021 2:15 pm

Imo, the obvious answer to why these splits happen has always been related to strong inflows of surface winds moving into the central arctic, generally from either the Atlantic or Pacific entrances. Although I have noted a few strong surface wind flows which also moved into the Arctic through Central Siberia. I have saved screenshots where this can be readily seen. These surface winds split the colder air over the Arctic which then causes the cold air masses to push southward.

The jet stream has been exceptionally wavy over the last several weeks. I think this is the largest distortion of the jet stream that I have observed since I started paying attention to earthnull. This was from 1/30/21.

I’m pretty sure it was the warmists who started the game of making every heat wave a sign of the climate apocalypse but every cold snap as nothing more than weather. Apparently according to that Swiss dude if you try to reverse these rules to rebut the warmists it makes you a wild eyed right wing nut.

From previous posts on wattsup:
The ability to predict is the best objective measure of scientific competence. These climate doomsters have a perfect negative predictive track record – every very-scary climate prediction of the ~fifty they have made in the past has failed to happen.

“MacRae’s Maxim”:
There is a powerful logic that says that no rational person can be this wrong, this deliberately obtuse, for this long – that they must have a covert agenda. I made this point circa 2009, and that agenda is now fully exposed – it is the Marxist totalitarian “Great Reset” – “you will own nothing, and you’ll be happy!”
The proponents of both the very-scary Global Warming / Climate Change scam and the Covid-19 Lockdown scam know they are lying. Note also how many global “leaders” quickly linked the two scams, stating ”to solve one we have to solve the other”- utter nonsense, not even plausible enough to be specious.

Warmists are clearly hopeless at predictions and climate science.

In 2002 I (we) also predicted solar-driven global cooling to commence circa 2020, and unfortunately that prediction is looking more and more probable – I’d rather be wrong – I’m getting old and hate the cold. The forecast low tonight in Calgary is minus31C – that’s the temperature, not the wind chill estimate, which would be even colder.

Sheveluch volcano powerful eruption happened 22 Dec 2020comment image
10mb temperature (red line) was falling back just prior to 22 /12/21 then suddenly took off for the next 2-3 weeks and by mid Jan it was more less over. From that point polar vortex gets weaker and weaker and jet stream goes into stronger and stronger meridional flow.

Kevin kilty
February 10, 2021 7:36 am

When there is a sudden and large outbreak of arctic air toward lower latitudes, that air must be replaced somehow. In many cases its replacement is warmer air from lower latitudes flowing into some sector of the arctic. Thus, a warmer arctic might be observed simultaneously with colder temperate regions. This is meridional flow, and we have observed periods when it is more or less intense since the beginning of modern observational meteorology post WWII.

No doubt, we’d all be better off with a majority of “science” journalists who do not suffer from Dunning-Kruger syndrome. I have no suggestions about how to correct the present state, however.

Reply to  Kevin kilty
February 10, 2021 7:49 am

When polar vortex is strong it keeps the Arctic jet stream in fairly regular circular circulation. The appearance of the SSD tends to weaken polar vortex which then looses control of the jet stream resulting in pronounced meridional flow, whole process may take few weeks from the initial SSD spike..
It is not entirely clear what causes the SSD but I strongly suspect winter eruptions from one of Kamchatka’s volcanoes, as I wrote here 3 weeks ago:
It appeared to me that within a few weeks of a Kamchatka volcanic eruptions sending huge volumes of ash high into atmosphere the SSW event occurs.
“Tue, 22 Dec 2020
Sheveluch volcano (Kamchatka, Russia): powerful eruption A few hours later, at 19:30 local time on today evening, another strong explosion detected by Volcanic Ash Advisory Center (VAAC) Tokyo produced spectacular ash plume rising up to 28,000 ft (8,500 m) altitude and extended about 130 km to the southeast of the volcano. Incandescence continues to be observed in the crater identified in satellite data.”

Leroux was sound in relation to mobile highs.
He did not move on to the upper atmosphere mechanisms over the poles that would be required to cause the phenomenon.
You have to get increases in ozone above the poles in order to force the polar tropopause down and push the mobile highs outwards and towards the equator.
When the sun is quiet ozone declines in the lower stratosphere below 45km and it was thought that that also applied above 45km (which is near the mesosphere). It was then found that it actually increased above 45km over the poles when the sun is quiet. Hence my mechanism.
A quiet sun increases ozone in the mesosphere which then falls towards the lower stratosphere within the descending column of air over the poles. That is where the extra ozone is coming from to cause sudden stratospheric warmings over the Arctic especially and occasionally over the Antarctic.

The ozone was what J.D. Haigh spoke about. But she wasn’t completelys aware at this time, what the role of decreased UV was what we know now better, see TCI, the not so old index.

Reply to  Stephen Wilde
February 10, 2021 3:22 pm

I’m not sure what the date was, the role of ozone was known or better known. On the one hand, Leroux’ paper about MPH is from 1991, and he was a synoptic meteorolgist.

“MPHs are the result of the downward air motion over polar regions, in connection with the permanent negative energy balance at the sur- face. Cooling, more intense in winter, creates an inversion, according to the synoptic situations, which is observable in the Arctic area below 2000 m. This “Arctic inversion is maintained in ~ts normal position and intensity both by surface cooling and by subsidence, as well as by warm air advection aloft” (Vowinckel et al., 1967).
As a result of their absolute or relative density and their dynamism, they force around them the uplift and the polewards devia- tion of the surrounding (less dense) airflows With these deflected airflows, they form a mobde “di- polar vortlce” consisting of an anticyclonic branch (i e., the Mobde Polar High), and a cyclonic branch (i.e., the low or “cyclone”)”

Citaion out of the Leroux MPH paper.

Reply to  Krishna Gans
February 11, 2021 3:31 am

There is confusion over the term polar vortex. Leroux focuses on the circumpolar flow in the troposphere but I refer to the descending column of air over the poles in the stratosphere. Both are referred to as the polar vortex in differing contexts. The media generally refer to the first one in the troposphere.
My hypothesis integrates the combined effect of both on the degree of meridionality or zonality in jet stream tracks.

If, at a certain time in winter, the Arctic was unusually warm, and nearby Canada or Europe was unusually cold, heat would tend to travel from warm to cold (as it usually does). In this case, it would cause the Arctic to get colder and the neighboring Canada or Europe to get warmer, resulting in a moderating of the cold snap.

Also, if cold air has moved out of the Arctic south into Canada and Europe, the air over the Arctic must be replaced by air moving north somewhere else. By the way, is Siberia unusually mild right now?

Which jet is stuck where? I teach students that the average position of the polar-front jet in the North Atlantic in late January is from Florida to the Iberian Peninsula. We are a little after January, but things change slowly until March. If you check out the position of the Jet Stream in the North Atlantic there appear to be two (the third is, I think, on the Arctic front), and they go from well north of Florida. One then tracks somewhat south, the other to the Iberian Peninsula. So … not really south of where it usually is this time of year.

Note also that they are strong, up to 160 kt (300 km/h). This indicates a large temperature difference, contrary to the hypothesis that the cause is Arctic warming.

Now, to be fair about it, last winter and the winter before were pretty mild by comparison to the single digit winter I have to put up with up here in my kingdom.
However, if there is a cycle pattern, as in the 1967 blizzard that hit Chicago (not in the forecast), and periodic episodes of mild winters followed by nasty blasts (1977, we got buried) full of snow and thundersnow w/lightning, and mild winters followed by beastly cold ones (Feb 2011 and now Feb 2021), isn’t that important enough to look at and analyze? And who can forget Boston Harbor being so full of snow dumped into it that it was completely clogged? Never mind Buffalo, NY being buried by a blast from the lake.

If there’s a pattern of nasty cold winters versus and that shows up in weather records, that has more bearing on the subject than some disgruntled sort sitting in his office, wondering why he’s cold and how to get rid of snow.

No, they just claim that they own it. It really belongs to the Mongols who inhabit the steppes, and they’re moving indoors these days. In fact, they are having a winter at least as bad as ours, because they did not harvest/stock enough hay for a brutal winter (duh!!! Guys, where do you live???) and their herds are dying off.
This looks like a pattern to me, that’s all.

So then the fact that winters are warming refutes the idea that winters are cooling due to global warming. That makes sense, I guess.

“Now that Europe and North America are getting blasted by unusually severe winter weather” 

People on the skeptical side of the Climate War ought to stop the whoop de doo about a few days of colder than normal. As near as I can tell from everything I look at and confirmed by my back porch thermometer, bitter cold snaps aren’t happening much any more.

Here’s the yearly low extremes for Milwaukee:comment image
Prior to 1996 fifteen to twenty below Fahrenheit happened quite often. For the last 25 years it’s happened once in 2019. NOAA’s Climate at a Glance confirms that winter lows are getting warmer. They do mess with the numbers, so it may not be that dramatic, but it pretty much agrees with the Wisconsin Climatology Office.

Our wonderful friends at Skeptical Science created the escalator and you have to give them credit, it’s pretty good. Normal weather doesn’t call for claiming we are being blasted by severe weather.

“NOAA’s Climate at a Glance confirms that winter lows are getting warmer.”

That would make sense since it has been warming since about 1980 to the present.

But now, it’s not warming, or, flatlining, if you will, so warmer winters may be a thing of the recent past.

One warming cycle is not enough to predict the future climate.

Tom & Climate Believer:

My point is, that just because we’ve had a week or so of colder than normal weather, it doesn’t warrant the terms, “Blasted by unusually severe … weather” Those of us on the skeptical side of the Climate War need to understand that the numbers are on our side, that’s why the Alarmists won’t debate. As such, we don’t need to exaggerate, cherry pick, create straw men etc. or on the other side of things allow them to set the agenda and create the terms & language.

Thanks for the replies. (-:

But even a short time of cold weather can prove that predictions by the alarmists are wrong. You can’t prove predictions like “snow is a thing of the past” with a few years without snow, but you can prove it is wrong with a few periods of snow fall every year.

Yes, I know the 2007 prediction said there would be some, but since 2010 the area the prediction related to has had more than one period of snow almost every year, and quite a lot some years (I happen to be able to pinpoint winter 2009/10, because I was training for a new job while finishing a contract so had a lot of driving on empty roads; winter 2017/18 because I returned to the country from living abroad, having snow the time we came to buy a car and find temporary accommodation, the time we moved in there and the time we moved back into our own house). So noting these frequent times of snow doesn’t prove we are right but it does prove they are wrong!

The Stratospheric Sudden Warming (SSW) is a phenomenon characterized by a rapid increase in polar temperatures in the stratosphere. The temperature increases more than a few dozen degrees in a few days in the boreal winter. In some cases the westerly polar night jet disappears and easterly winds appear during the warming. JMA is monitoring SSWs as one of the Regional Warming Centers. The warming is called a “Minor Warming”, when the polar temperature increases more than 25 degrees in a period of a week or less at any stratospheric level. If the zonal mean temperature increases poleward from 60 degrees latitude and the net zonal mean zonal winds become easterly at 60 degrees latitude at 10 hPa (32 km) or below, it is classified as a “Major Warming”.

Thanks for your comments.

It should be noted that this warming occurs at 10hPa, about 30,000m in altitude, far above the tropopause which normally prevents lower level mixing by convection. But every other year this mixing happens, only in the stratospheric polar vortex, which only exists in winter due to temperature gradient created by lower solar incidence angle. The tropospheric polar vortex persists year round and is normally isolated from the stratospheric vortex.

To understand this it is necessary to understand vertical Rossby waves. This warming is virtual, colder stratospheric air pushed lower and compressed isoentropically, so essentially no change in potential temperature.

Yes, the reddish-orange structure is the space-time profile of the stratospheric polar vortex, which intrudes downward into the troposphere in January. But only in response to a previous upward intrusion, as Charney-Drazin explained, by the tropospheric polar vortex (aka the ‘wavy’ circumpolar Rossby belt) which is actually the edge of the planetary polar front jet stream. The undulations of the NH coastlines and mountainous topography (‘orography’) are largely the cause of these vertically travelling Rossby waves.

Charney, J.G. and Drazin, P.G.,
Propagation of Planetary-Scale Disturbances from the Lower into the Upper Atmosphere [1961]

These two types of polar vortices are otherwise completely independent and isolated from one another.

More recently, the converse relationship that the zonal mean zonal wind anomalies slowly propagate from the subtropical upper stratosphere to the polar region of the lower stratosphere and the troposphere during the boreal winter, is also noted (Kodera et al. 1990). It has been shown that SSWs occur in association with slowly propagating zonal mean zonal wind anomalies, and the related changes in the troposphere exhibits the Annular Mode (AO) (Thompson and Wallace 1998) like structure (Kodera et al. 2000). Baldwin and Dunkerton (1999) also showed that the downward propagation of the AO from the stratosphere to the troposphere occurs in association with SSWs.
The daily AO index and its forecasts using MRF and Ensemble mean forecast data are shown for the previous 120 days as indicated and they are normalized by standard deviation of the monthly AO index from 1979 to 2000. A 3-day running mean is applied for the forecast indices.comment image

During extended periods of low solar activity, the distribution of ozone in the Northern Hemisphere is highly asymmetric. Ozone during such periods accumulates first over northeastern Siberia. This results in strong polar vortex blocking in the stratosphere. Later in the winter, ozone falls over North America in so-called stratospheric intrusions. A disruption of the polar vortex in the lower stratosphere occurs, allowing Arctic air to flow southward.
The increased cold this winter may also be related to the drop in water vapor during La Niña.comment image

 In Central Europe, heavy frost may persist almost until the end of February. Interestingly, the lows pushed to the south of Europe bring very large amounts of snow in Germany and Poland. This winter may remind someone of the 1970s.

Some thought that the recent strong increase in solar flux of 10.7 cm , heralded an increase in solar activity. How wrong they were.comment image
‘The solar radio flux at 10.7 cm (2800 MHz) is an excellent indicator of solar activity. Often called the F10.7 index, it is one of the longest running records of solar activity. The F10.7 radio emissions originates high in the chromosphere and low in the corona of the solar atmosphere. The F10.7 correlates well with the sunspot number as well as a number of UltraViolet (UV) and visible solar irradiance records.’

UV increases after solar flares, so it indicates sunspot strength ( strictly speaking sunspot magnetic activity). This can now be seen in the solar disk, as current sunspots produce at most single C-class flares.

In my opinion, ozone as a diamagnetic is repelled by the magnetic field of the solar wind. When the solar wind is strong the wind in the polar vortex accelerates and ozone from the tropical stratosphere cannot get over the polar circle.

“duping the gullible media journalists”?

I think not. They aren’t being duped. They just don’t give a damned if what they are “reporting” is accurate as long as it make good copy that sells. Time and again we see them going back to so called “experts” that have predicted catastrophic changes in weather or climate that have not come to pass and for which there is no indications they will. They continue to treat such scammers as legitimate authorities.

Recently there was a cartoon shown here from Josh showing year after year how we have been warned year after year after year that it was the last year we had to take drastic actions to stop or mitigate a coming climate doom. Show me where in the greater media those that have spewed this stuff year after year are challenged or mocked or held accountable in any way! No instead the same media and so called “journalists” continue to “report” their nonsense as if it is based on legitimate science.

A few years ago we went to the Grand Targhee resort for my sons birthday. It’s located in Alta, Wyoming just over the pass from Jackson Hole. They have had over 24 feet of snow this year and currently have a base of 92″.  

All over the US, in the NE and West ski resorts have had great snow reports. This on top of some records broken last season when Squaw Valley remained open longer than it ever had in it’s relatively long history. ! Across the pond the same thing! A super year on the slopes if not for COVID, Exactly the opposite of what the climate idiots reported would be happening by now.  Show me where some “journalist” from the greater press has gone back to the “experts” that made the predictions that ski industries would suffer due lack of snow due to climate change and called them out on their failed predictions!

These so called climate experts are never held accountable for their silly predictions of doom and gloom even though they are never correct. In fact the ones that make the silliest predictions and have the worst records are who the press seems to seek out for their stories. 

When are those that have bought into this constant stream of climate doom BS going to wake up? They have been pumping this catastrophic global warming/climate change crap for nearly four decades now with idiots proclaiming every year is the last year for drastic action to hold off uncontrollable warming. And for a couple decades before that the “experts”, were saying we were cooling and headed for another ice age and were writing the President and proposing all kinds of crazy government programs to try and alter the climate.  

P. Gosselin is far too kind.

The idea never passed the smell test. I teach meteorology (to pilots), so know a little about jet streams. They form at the polar front (well the ones in question do, they are called polar front jets) due to the temperature difference between the polar and tropical air masses. So if the arctic warms that temperature difference reducing means that the jets get weaker and shorter (it’s only a jet stream if the wind is over 110 km/h, so in weakening the bits that would have been, for example, 120 km/h might weaken to 100 km/h and no longer be jet streams).

However it is more the shape we are considering here, “wavier jet streams”. Fronts where the temperature difference is large are more active, where it is small are less active. The curvature of frontal wave is itself caused by the temperature difference, as the warm air rises over the cold air causing the frontal depressions (low pressure regions) you can see in bad weather on your home barometer. I cannot see any scenario where a reduction in temperature gradient (as predicted by those models forecasting CAGW) due to warming Arctic can increase the waviness caused by that temperature gradient.

Stratospheric Intrusions are when stratospheric air dynamically decends into the troposphere and may reach the surface, bringing with it high concentrations of ozone which may be harmful to some people. Stratospheric Intrusions are identified by very low tropopause heights, low heights of the 2 potential vorticity unit (PVU) surface, very low relative and specific humidity concentrations, and high concentrations of ozone. Stratospheric Intrusions commonly follow strong cold fronts and can extend across multiple states. In satellite imagery, Stratospheric Intrusions are identified by very low moisture levels in the water vapor channels (6.2, 6.5, and 6.9 micron). Along with the dry air, Stratospheric Intrusions bring high amounts of ozone into the tropospheric column and possibly near the surface. This may be harmful to some people with breathing impairments. Stratospheric Intrusions are more common in the winter/spring months and are more frequent during La Nina periods. Frequent or sustained occurances of Stratospheric Intrusions may decrease the air quality enough to exceed EPA guidelines.comment image
