From Dr Roy Spencer
January 31st, 2019 by Roy W. Spencer, Ph. D.

It’s much easier to devise and promote a climate change theory than it is to falsify it. Falsification requires a lot of data over a long period of time, something we don’t usually have in climate research.
The “polar vortex” is the deep cyclonic flow around a cold air mass generally covering the Arctic, Canada, and Northern Asia during winter. It is irregularly shaped, following the far-northern land masses, unlike it’s stratospheric cousin, which is often quite symmetric and centered on the North and South Poles.
For as long as we have had weather records (extending back into the 1800s), lobes of cold air rotating generally from west to east around the polar vortex sometimes extend down into the U.S. causing wild winter weather and general unpleasantness.
We used to call this process “weather”. Now it’s called “climate change”.
When these cold air outbreaks continued to menace the United States even as global warming has caused global average temperatures to creep upward, an explanation had to be found. After all, snow was supposed to be a thing of the past by now.
Enter the theory that decreasing wintertime sea ice cover in the Arctic (down about 15% over the last 40 years) has tended to displace the polar vortex in the general direction of southern Canuckistan and Yankeeland.
In other words, as the theory goes, global warming sometimes causes colder winters. This is what makes global warming theory so marvelously adaptable — it can explain anything.
In the wake of the current cold wave, John Christy skated into my office this morning with a plot of U.S. winter cold waves since the late 1800s. He grouped the results by region, and examined cold waves lasting a minimum of 2 days at a station, and 5 days at a station. The results were basically the same.
As can be seen in the plot below, there is no evidence in the data supporting the claim that decreasing Arctic sea ice in recent decades is causing more frequent displacement of cold winter air masses into the eastern U.S., at least through the winter of 2017-18:

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).
Now, I suppose that Arctic sea ice decline could have some influence. But weather is immensely complex. Cause and effect is often difficult to ascertain.
At a minimum we should demand good observational support for any specific claim. In this case I would say that the connection between Eastern U.S. cold waves and Arctic sea ice is speculative, at best.
Just like most theories of climate change.

“If the Polar Vortex is due to Global Warming, Why are U.S. Cold Waves Decreasing?”
That one’s easy: Because of “Global Warming”, silly. Or is it “climate change”? Hard to keep up with the narrative.
I think it is also about climate extremes. Some places in the midwest will be almost 60 degrees warmer by Sunday, although I am sure that will bring a lot of relief to the millennials that have never seen it this cold before 😀
So basically it will go from 75d below freezing (32F) to 15deg below freezing
I think the operative word there is “millenials”, i.e. it is the noisy, (anti)social media connected, real world head up their arses millenials who are the target market for all thes CAGW/CC drivel. It is straight out of the Goebbel’s propaganda playbook.
What amazes me is that so many seemed to be bamboozled and unable to see that everything is Global Warming or da, da, da, daaaa Climate Change. And then I realize for the past two generations the public school systems and our institutions of Hgher Indoctrination have been very successful at the mission of fooling most of the people all of the time. Of course they have been supported by the Primary Media outlets and Hollywood so it comes as no real suprise.
We have a new generation where a majority believes the climate never changed around the world before the burning of fossil fuel and that socialism has never failed anywhere it has been practically applied. They will need to suffer before they will understand how badly they have been lied to.
Take away electricity every time they flip a light switch and let them listen to their growling stomachs while shivering in the dark and they will finally understand. Unfortunately by then it will take a revolution to unseat the dictators and massive bureaucracy (aka swamp people) who peddled these lies.
Notice that climate disruption fell from vogue?
Glad to see the back of Climate Weirding even though a huge own goal.
Yes climate change/gw causes the polar vortices but also must cause fewer of the to occur. 🙂
It can also do the opposite if you want, waddayou want? More? Less? what? Getcha’s explinations over heres. Cheap!
It is utterly outrageous that Dr. Spencer is actually using observational data to disprove the assertions of climate alarmists. Doesn’t he realise that this will hurt their feelings?
The climate communicators have it covered. Dr Spencer’s data don’t have a chance.

I picked that up on Eric Holthaus’ twitter feed, btw. He’s a meteorologist, yano. Really on top of his game.
Also sounds kinda pervy.
He’s a full blown nutbar. Fits right in with the AGW crowd.
I think in another time and place he would have been the village idiot.
I think I am gonna go onto my twittermachine and tell ms. girlyratfish the obvious: Loose boobies, whether the deathly cold variety, or of the tippy-top of the great warmy-warmy sort, are more properly ascribable to a theory which is reaching old age.
It is even worse when stretch marks, from being badly contorted into every possible extreme shape for so many years, mar the surface of the appendages in question.
It has been rather conclusively demonstrated that bras, most eckspeshally the full support ones, may give the illusion of preventing sag and other forms of looseness, but that actually they do the opposite, and going braless keeps boobies far more resiliently firm and highly placed in their proper domain, which is of course high up on the chest and pointing ever skyward towards the real villain.
It is a third wave feminazi lie that men cause all problems on the Earth.
As is toxic-masculinity.
In fact, only a lifetime of proper male attention can save the boobies, although it is sadly too late for some, many can even yet be saved from the sad fate of looseness.
Now, that real villain…?
It is the Sun, dammit…the Sun.
We must spread the word, before it is too late!
Burn a bra, and save them boobies!
🤩🤩🤩🤩🤣
Speaking of misleading terms, why to we refer to the beauty of breasts as ‘boobies’? When they make their appearance, does anyone boo? Maybe a boo-hoo when this items of affection are out of reach.
No, the sight of beautiful breasts usually brings out cheers. Therefore, I submit we change this misleading term to Yaybies!
If the AGW can corrupt ideas, we can at least improve on one.
Just a thought.
Yes, he will never get a job at Buzzfeed, Vice, Yahoo, or any one of the other million or so clickbait factories posing as journalism. Let alone on CNNCBSABCNBCNPRPBS, etc.
Then again, luckily for us, neither will all those recent liberal arts grads who write for free but have wonderfully inaccurate titles such as “Senior Science Correspondent” or “Senior Science Editor”.
I believe most of the reduction in Arctic Ice is due to the Gulf Stream getting stronger and pushing much farther NorthEast through the Barents Sea to Yuzhny Island. The Canadian Arctic has had its ups and downs, but is basically not trending very much. See http://polar.ncep.noaa.gov/sst/ophi/color_anomaly_NPS_ophi0.png for example.
Gotta be careful. You can prove anything you want by selecting the range of data that shows what you want.
Drs. Christy and Spencer used the whole range of relatively reliable data available, ie since 1895.
To me, that looks pretty careful. The data from AD 1770 to 1894 just aren’t fit for purpose in most places.
It goes back to 1895 – are you suggesting that if you go back further it will show something different?
From the El Niño year1998 until now, the positive correlation is, what’s that word…..”unequivocal”….
/s
To detect changes in trends you have to select various ranges of data.
Another possible explanation (and one that is equally plausible) is that global warming does in fact disrupt the polar vortex, but in doing so, it increases global cooling which thus counteracts the effect of global warming. This is a negative feedback or damping phenomenon which would explain the relative stability of our climate.
I think what you are really saying is that more legitimate science needs to be done to study and try to explain the observed climate patterns. Unfortunately, in today’s world, the scientific method is going extinct.
I’m not sure that is possible. This is “cold” moved elsewhere, not “new cold”.
This isn’t even “cold” as in “absence of heat”. This is cold caused by heat! Far out, eh?
It falls under the new narrative … “EXTREME weather”
Polar Vortex … EXTREME weather
Decreasing cold waves … EXTREME weather pattern changes
As long as the “messaging language” keeps morphing to fit the FAILURES of Global Warming … we will be facing an “existential threat”.
Exactly right, but for the wrong reason. The slow build up of average global temperatures over a century wasn’t scaring anybody much to do anything much, because we are short-term creatures. So a new narrative was needed, one that would scare us into immediate action.
“Extreme weather” was the solution, something that is happening NOW!
This is all about moving the threat from sometime well into the future to the present.
I accept your friendly Amendment to my statement.
“This is all about moving the threat from sometime well into the future to the present.”
The threat may never materialize. Judging from past climate models I put a high probability on it.
Does anyone else see what I see? If you where to engage in the infamous curve fitting, it looks like the graph would be an inverted temperature graph. …. decreasing from 1895 to around 1950, then increasing to around 1980, then decreasing again till about 2005 ……. and …. ummm … looks like it is increasing again in the last 13 years again.
I’m going to predict that it is going to continue to increase for the next 15-20 years. Would love if one of you data, curve fitting, brighter than me types would graph that out.
What I see is that there are periods of low instance of polar outbreaks, and periods of higher frequency of them.
These periods of time can be short or long.
And throughout the record, we can see years of very high incidence directly adjacent to years of very low incidence.
And sometimes we can see a year with high incidence sandwiched between two years of low incidence.
It looks random to me, with some periods in one mode and others in another mode and some periods that are just scattered.
If we look at the history of such things as the citrus fruit industry in Florida, for as long as there has been organized agriculture in Florida, and in particular a citrus industry, there have been long periods of time with no freezes, and in those periods people planted citrus further and further north.
And then there was a catastrophic freeze caused by a polar outbreak extending all the way deep into the peninsula.
When I moved to Central Florida in 1982, there were decades old citrus groves all across central Florida.
The areas adjacent to SR 59 west of Orlando, all along the Highland Ridge. Amazing huge groves of giant trees that had to have pathways carved into them to allow access for spraying and harvesting, and to allow sun to penetrate. The trees were topped to keep the fruit from being out of reach.
A series of freezes killed them all in the 1980s.
These groves had survived many hard freezes in the 1970s, but had died anyway.
There were a lot of freezes in those years, and a few in particular were unusual in that it was very cold AND very windy, for an extended period of time, lasting days.
This prevented saving the trees using the methods that had worked in equally cold weather in previous events: Spraying with water. Simply put, it was too windy to coat the trees evenly with a layer of protective ice.
There were other factors, such as a prohibition on using fires made from old tires and such, but with the wind these would likely have been ineffective anyway.
But this event was only unique in that it was in our lifetime, and people have short memories. Or they think that history will not repeat itself.
If you live in Florida your whole life and never see a outbreak severe enough to kill trees no matter what you do, you might think it cannot happen.
But it does, as it always has.
In the 1890s there was a severe freeze that ended agriculture in Florida for many people, industries, and crops, and for a long time. But then people forgot. By the time the series of hurricanes in the 1920s and 1930s hit, there was once again a huge citrus industry that was wiped out, or nearly so, and many areas, including some spared by the 1890s events.
Looking back, it has been the case that decades of low or no instance of severe killing freezes have alternated with catastrophic events.
The difference is, back then no one tried to say weather was because of people.
They were known to be acts of God.
Sorry, that should say SR 50 west of Orlando.
Edit button please…
The odds are that what we can expect as a result of global warming is to see more
of this pattern of extreme cold. – – – Dr. John Holdren, The White House – 1/8/2014
Source: You Tube – The Polar Vortex Explained in 2 Minutes
If what Dr. Holdren said was true, we should have been seeing cold snaps like this more frequently over the last thirty years. We haven’t, we’ve seen less, Dr. Holdren was wrong.
The phrase ‘Dr. Holdren was wrong’ is so common it should have a keyboard shortcut built into every operating system. Along with ‘Paul Krugman was wrong’
Greg61 February 1, 2019 at 6:25 am
First chuckle of the day (-:
Read Dr. Holdren’s 1972 book about energy. No one was ever more wrong.
Falsification only requires proof of source bias.
Averaging data over distance without verifying reliability AND ACCURACY of the involved stations is source-biasing.
ta-da.
Averaging data over distance? Try thinking maybe? It’s pretty simple to understand what Christie did, he took the average number of times that these official weather station dropped below the 5th percentile temperature for two days (filtering outliers) during a single winter and plotted that for each year going back to 1895.
Without verifying reliability and accuracy? These are official weather data. Verifying reliability and accuracy does not mean adjusting data to match preconceived conclusions.
And as it’s the same official data that the alarmist use to support the CAGW scare, if “not verifying reliability AND ACCURACY” is the what Prjindigo claims in order to”falsify” Christie’s work here, we’ll he’s also falsified the entire alarmist narrative at the same time. well done you, Prjindigo?
– it can explain anything.
However, it can forecast nothing.
It is interesting that if you consider all the predictions by alarmists you will find them mostly wrong. Predictions made with some knowledge of the subject should prove correct more often than not. Logic therefore explains that propaganda or bias is driving the predictions.
Or perhaps it could be their knowledge of the subject is lacking.
Ayup, clearly THEY don’t know what THEY think they know
The 1930’s, notable mostly or very hot summers seems to also been a period of very cold winters. Could that be due to very dry air throughout these years with insufficient water vapor to reject enough of the sun’s heat in summer and insufficient water vapor to retain the surface warmth during the winter?
Like Tony Heller, I want to see that chart plotted back to at least 1960 because I suspect the period ’60-’79 was a mirror of the ’79-’98 years.
Now that the Arctic sea ice is stable, is the frequency of excursions also stable?
“I want to see that chart plotted back to at least 1960…”
huh?
The least you can do is calculate the R square value for your linear regression analysis.
You have a huge amount of variation. My guess is the R square value is way below 0.5 and you cannot claim anything.
Easy for you to prove me wrong!
Arctic sea ice summer minimum extent has been growing since its post-1979 record low in 2012, and flat since 2007. The low years of 2007, 2012 and 2016 each suffered August cyclones, with two in 2016. The winds spread out the floes and pile them up, reducing area covered by at least 15% ice.
I’ve been looking at these events on and off for about dozen years, during that period I have registered notable polar vortex events January 2009, January 2014 and this January of 2019. The five years separation may be a coincidence since I don’t know of any similar period related to climate. There is of course el Nino , but it varies, it was many months ago and can’t see a direct connection.
These polar vortex events occurred after low solar activity periods during a minimum with the two periods in 2009 and 2019. The other polar vortex event in 2004 after low solar activity period during maximum. Despite being at the peak of solar activity, around 70 SSN was rather low for it. It was around 60 SSN to 80 SSN for most of the time when usually above 100 SSN. In theory a weak period during a solar maximum could have the same influence on the polar vortex as a minimum. All polar vortex events occurred with a decline of solar activity prior to it
http://www.woodfortrees.org/plot/sidc-ssn/from:2008
Hi MG, you are absolutely correct, but of course any new idea is automatically dismissed by ‘know it all excepts’.

As I have said in my comment further down:
“There could be one of two reasons for this:
– polar vortex is electrically charged by cosmic rays or solar activity particles.
– …….”
1) at the time of solar maxima there is maximum in solar radiation
2) at the time of solar minima thera is maximum in cosmic radiation
In either case polar vortex is strongly ionised, and rotating at high velocity in presence of bifurcated magnetic field. Basic laws of physics imply splitting of vortex following the “lines” of magnetic field intensity.

Spreading out end eventually split vartex looses its strength, consequently it’s hold on jet stream is weakest allowing it to buckle and loop southward.
Locations of two magnetic peaks in N. Canada and central Siberia locks jet stream in fixed position talking warm Pacific air to Alaska and cold Arctic air to N. America and Europe.
“I want to see that chart plotted back to at least 1960”
Provide the satellite measurements of Arctic sea ice first. And global temperature; remember you can’t rely on the much modified thermometer measurements because they don’t even cover the whole globe.
The chart I see goes back to 1895.
Let’s see whether I’ve got this straight:
Skeptics can point to decreasing spans of cold, when we want to defeat claims of global warming, and alarmists can point to decreasing spans of cold to support claims of global warming.
It’s win/win.
Often during SSW- sudden stratospheric warming polar vortex spreads out and eventually splits-up into two independent vorteces which, for as yet fully unexplained reason, end up above the two locations of strongest magnetic field in the North Hemisphere.

There could be one of two reasons for this:
– polar vortex is electrically charged by cosmic rays or solar activity particles
– Earth’s rotation axis has irregular oscillation i.e. the longer term Chandler’s wabble that might be responsible for both.
I tend to favour the first, but if anyone might have another explanation it would be welcome.
It is important to know that rise in the Siberian leg of the field has been prominent in the last 100+ years, while the Canadian has been loosing strength at the same time, the crossover point was around 1995-6.
“There could be one of two reasons for this:”
No, the reason is meteorological/topographical.
The two vortices are attracted to each of the two major land masses … and that generate cold over snowfield in winter.
The radiating surfaces are constantly cooling any advected airmass.
They will not end up over either the N Atlantic and the N Pacific for that reason.
The Rockies preferentially bend the PJS south to its lee into Canada due to conservation of total vorticity upon a westerly flowing over it…..
Centre of continental mas is not at the Hudson bay but much further south, but as it happens the Hudson bay area is one of two centres of strongest magnetic field in the N. Hemisphere, the other being in central Siberia.
Continental masses are there every winter, but the polar vortex gets maximum ionisation following the time of solar maxima (solar radiation) or the time of solar minima (cosmic radiation), i.e about every five years resulting in the cold snaps of 2004, 2009, 2014, 2019.
Perhaps you might do well to consider alternative way of looking at physics of the matter. See my reply to Matt G further above.
vukcevic
“- polar vortex is electrically charged by cosmic rays or solar activity particles”
Vuk I think the only reason were here, is because of the processes from inside Earth itself ,generating electricity and then magnetism.
“Together, these signals form the magnetic field that protects us from cosmic radiation and charged particles that stream towards Earth in solar winds.
Measuring the magnetic field is one of the few ways we can look deep inside our planet. As Chris Finlay from the Technical University of Denmark noted, “We know more about the Sun than Earth’s core because the Sun is not hidden from us by 3000 km of rock.”
The field exists because of an ocean of superheated, swirling liquid iron that makes up the outer core. Like a spinning conductor in a bicycle dynamo, this moving iron creates electrical currents, which in turn generate our continuously changing magnetic field.
Tracking changes in the magnetic field can, therefore, tell researchers how the iron in the core moves.”

Yep.
Earth’s field variability follows solar activity
http://www.vukcevic.co.uk/GMF-SSN.htm
And in concert the two control global temperature variability

Climate science has become ad hoc storytelling.
You mean like the Aesop’s fables for children, at least those have morality lessons.
Exactly, fables. Used for political expediency rather than moral instruction.
icisil,
The most entertaining part of the climate consensus is that it’s promoters perform world class post hoc arm waving so frequently.
Was it just me, or did you notice that arm waving take on a feverish pitch after the severe 12-year hurricane hiatus, the 18-year warming hiatus and expired fulfillment dates on a number of their false prophecies?
Unfortunately, those who understand math and science aren’t as good at this as the alarmists.
As I’ve said: unless its an evacutation order, you can usually ignore both the loud end of the megaphone, and the small mind at the other end of it.
It is very easy to troll warmistas, but few who are actually informed, and given to the pursuit of knowledge, are much interested in being the source of misinformation.
Also, there are many ways to be wrong about some thing or anything.
But a much smaller target when it comes to being right.
This is a bit off topic but relates to falsified information re: climate change and insurance issues. It was just published today.
https://business.financialpost.com/opinion/terence-corcoran-cbc-admits-it-wrongly-reported-hyped-up-insurance-climate-risks
Could this story be true? If so, what will the ramifications be?
It doesn’t stop the BS train from rolling down the we ain’t thinking tracks.
Mindless politicos at the switch
If there are more cold waves…it’s global warming.
If there are less cold waves… it’s global warming.
When a theory is “consistent” with every possible outcome it is not falsifiable. Therefor it is not science.
Yes, here in Toronto, models were used to show that both more spring runoff, and less spring runoff were the “new normals”. Years apart, of course. And the period in between was ignored for some reason, being normal.
Luckily for Big Green, they can rely on people a) trying to do the right thing (with as little effort as possible), and b) having short memories (and little to no science or math).
And it helps the greens that the compliant news media never calls them out on past predictions that never happened and are inconsistent with the new predictions.
Quick look at the data and my takeaway is a multi-decadal pattern. There is a higher than average period in the early 1900s, a slow decline to a lower than average period in the 1930-1950s and then a rise into the, 1980s, and a decline into the 2000s. There could be a current rising trend, although the data is limited to make that determination.
Anyone (Calling Bob Tisdale) want to correlate this activity with longer term ocean temperature trends? My theory here (more a guess) is that this will correlate nicely with trends in PDO, AMO or basin temp trends – which no one should be surprised with.
I have no idea if a warm Pacific and a cold ATL may open the door for the Polar Vortex to be more easily displaced, whether a particular ocean pattern may be more conducive to SSW in the winter months, etc. But that is what science and data and analysis is supposed to identify.
The fact that so many ignorant elected officials, wannabe elected officials, and even bureaucrats at places like NOAA are even hinting that cold outbreaks are due to anthropogenic activity is silly on its face. A little analysis may show how silly.
I agree that the idea that oceans influence the atmosphere more than vice-versa. I would predict the Pacific and Atlantic ocean temp anomaly would match the waves graph above showing top US 5% cold waves, and I would also predict a nice match for a graph US temps vs ocean sea temp anomaly. Those would be nice graphs to compare vs CO2 levels.

A better question would be if nothing cannot be attributed to AGW, what does it actual mean ?
For can something which is ‘everything ‘ have real meaning for to have a meaning you must have boundaries of some from to know what you are and are not .
Of course this event was going to be jumped as ‘proof ‘ of climate doom , so both hot and cold events have been before while the claim ‘weather is not climate ‘ as long been forgotten.
And the reason for that , because it was be noted that doom ,of the type that was claimed to arrive soon, simply was not as tipping points and countdowns run their course. So when reality failed to supply they had to resort to grapping anything they could to be the train in track. And this action was required not because of the strength of their ‘settled science ‘ but because of the weakness in their actual science. That guess work and ‘better than nothing ‘ turned out to be a bad way to understand chaos and in an area where predictions for more than 72 hours ahead can be wildly-off because of so much that is unknown or poorly understood . Its not in anyway ‘settled ‘ no matter how much ‘faith ‘ you have or how often you combine ‘heads you lose and tails I win’ and ‘find the lady ‘ in your professional practice.
Please do not drink and drive.
Or write.
Polar Vortex?
Global Warming?
We used to just call it “WINTER”.
I’m 55 and was raised to be afraid of Snowball Earth. Went and seen my dad this morning and he said the exact same thing, word for word. My only response, Climate Happens. 😉
CO2’s temperature influence is in the atmosphere, which has a tiny fraction of the thermal inertia of the ocean/atmospheric system. A comparison would be an elephant (the oceans) and a mouse (the atmosphere), and arguing that the mouse is dragging around the elephant! Nonsense!
Mainstream climate science has no understanding of the ocean thermal cycles, which have been identified through observation over hundreds of years. Not only do they not understand them, they have no desire to even try! For 30 years, their entire focus and funding has been around increasing CO2, and the idea that a mouse can push around an elephant!
The declining polar ice over the last 40 years is well correlated with the Atlantic multidecadal oscillation (AMO).
From 1940 to 1973, the North Atlantic cooled by about 0.5 degrees C. From 1973 until 2008, the North Atlantic warmed about 0.6 C! Over the last 10 years, the North Atlantic has been cooling again, and appears to be moving towards another negative phase. All of this happened while CO2 was steadily increasing, apparently having no influence whatsoever on the powerful AMO cycle!
If the AMO trend towards a cooler phase continues, Arctic sea ice will begin to expand once again over the next 5 to 10 years, destroying the only significant physical observation that the warmists had to support their ‘mouse-stronger-than-elephant’ theory’.
No no, expanding Arctic sea ice will be a proof of global warming like it did a few years ago in the Antarctic.
Yes, it will be “proof” that global warming has melted ice in Greenland, reducing salinity of the water, slowing the flow of the Gulf Current, and freezing the Pole. The alarmists already have that covered.

I found this attempt to link the polar vortex to global warming this morning.
https://ca.news.yahoo.com/climate-change-behind-weeks-extreme-090000332.html
It lectured me with this, AGAIN.
“The important thing to remember when discussing climate change is that climate and weather are two separate entities.”
And immediately followed with this.
“Weather is the state of the atmosphere pertaining to things like wind, moisture, temperature and more that occur on a day-to-day basis. Climate, on the other hand, is the average weather in one place over a long period of time.”
In other words are they not saying that climate is just a bunch of weather. Or climate is the sum of weather events divided by some number of weather events. My conclusion has to be that climate is weather and weather is climate. What is double speak.
Thank you.
There were stories the other day suggesting that the SSW event from Dec/Jan was the cause of the cold outbreak. Then Borenstein was trying to say that the SSW was caused by some warming above Morrocco with no explanation how that could warm the stratosphere at 10 hPa above eastern Siberia which is where the SSW showed up.
6 appears to be the magic number in the last 100 years. Not since 1917 was a year that hit 6 or higher and then have the next year even higher. 2018 was about 7, so that predict this year (2019) will be less, maybe around 4 to 5.
