Where The Warmth Is

Guest Post by Willis Eschenbach

I got to thinking about the “hiatus” in warming in the 21st Century, and I realized that the CERES satellite dataset covers the period since the year 2000. So I’ve graphed up a few views of the temperature changes over the period of the CERES record, which at present is May 2000 to February 2017. No great insights, just a good overview and some interesting findings.

First, here are the raw CERES global average surface temperature data, the seasonal variations, and the anomaly that remains after removing the seasonal variations.

Figure 1. Seasonal decomposition of the CERES surface temperature data. Statistical results (bottom line) are adjusted for autocorrelation using the method of Koutsoyiannis.

So … what are we looking at? The top panel shows the raw data, the actual temperature variations. The middle panel shows the repeating seasonal variations. The bottom panel shows the “residual anomaly”, the variations that remain once we’ve removed the repeating seasonal component of the signal.

The bottom panel, the residual anomaly, is the panel of interest. You can see how little the temperature has varied over the seventeen years of record. The El Nino of 2016-2017 is quite visible … but other than that there isn’t much happening.

There is one thing that is interesting about the residual … other than warming as a result of the 2016-2017 El Nino, the temperature anomaly only varied by about ± 0.2°C. Among other places, I’ve discussed what I see as the reason for this amazing stability in a post called Emergent Climate Phenomena.

The next question of interest to me is, where is the temperature changing, and by how much? Here is a Pacific and an Atlantic centered view of the warming trends recorded by CERES, in degrees C per decade.

Figure 2. Temperature trends around the globe.

So … what is of note in these global maps? Well, both the poles are unusual. The area around Antarctica is cooling strongly, and the Arctic is warming. Presumably, this is why we’re getting less sea ice in the North and more sea ice in the South. It also affects the hemispheric averages, with the Northern Hemisphere warming and the Southern Hemisphere basically unchanging. Figure 3 shows the average decadal temperature trends by latitude band.

ceres decadal temperature trends 2017.png

Figure 3. Average decadal temperature trends by latitude band.

As you can see, the only parts of the planet where the temperature is changing much are the Southern Ocean around Antarctica, and the area above the Arctic Circle.

Next, in Figure 2 you can see that the North Atlantic is generally cooling. On the other hand, the Pacific is mixed, with areas of slight cooling and other areas of slight warming. Go figure.

On land, northern Russia, parts of the Sahel, the Gobi, and western Australia are warming. On the other hand, the upper Amazon is cooling strongly. So it looks like some (but not all) deserts are warming, and some (but not all) tropical forests are cooling … why?

I haven’t a clue. In my opinion, the most important words that anyone studying the climate can learn to say are “I don’t know.”

At the end of the story, I’m left with my usual amazement at the stability of the system. Despite being controlled by things as evanescent as winds, waves, and clouds, the temperature anomaly doesn’t vary more than about two-tenths of a degree. Nor is this due to “thermal inertia” as many people claim. Look again at Figure 1—the temperature changes by four degrees C peak to peak in the course of a single year, and changes by a degree and a quarter C in a single month, but the anomaly barely budges. To me, this is clear evidence of strong thermoregulatory systems, but of course, YMMV …

Sunshine today after rain, the Pacific ocean glitters in the far distance, the earth abides …

Regards to all,

Please be aware that while my request is polite, if you ignore the request I may say unflattering things about your ancestry, commenting habits, or cranial capacity … be warned.

DATA: For the temperature data I have used a straight Stefan-Boltzmann conversion of the CERES EBAF Edition 4.0 datafile showing upwelling longwave radiation. The dataset is available here. I have checked and compared this temperature dataset to a variety of other temperature datasets (HadCRUT4, Reynolds SST, HadISST, TAO buoy data) and found very little difference.

RSS and UAH don’t cover latitudes above +85 degrees, below -85 degrees and, in the cases of TLT and TMT (lower and mid-troposphere), some areas with land above 1500 m altitude.

As far as I know, CERES does not measure surface temperature. Could be estimates from the MODIS imager that the CERES team passes through… but I wouldn’t trust MODIS infrared for surface temperature because it’s too prone to cloud contamination, and so they only have temperature info on clear days… an obvious source of bias.

Regardless, CERES data seems to agree more closely to with UAH than RSS. I suspect that remain the case and RSS will continue to diverge over time.

Reply to  Peter Langlee
March 24, 2018 11:13 pm

Without checking the orbital details, I think both platforms probably have similar orbital inclination: near pole but not actually over the poles.
The reason that UAH and RSS don’t cover higher latitudes is because of gaps in the data. There is some data but are too many holes to get a representative coverage.
Coverage may come down to viewing angle.of the instruments used and the swath overlap on the ground.

Roy, you really should read to the end of the post before commenting …

Willis, something as fundamental as that should be in the article, probably near the top, not in a PS after the usual boilerplate “please quote me” spiel.

PS—As always, my polite request is that you

When I got that far, I said, yeah OK, the usual ( perfectly reasonable ) Willis closing paragraph and stopped reading because I’ve read it a hundred times. I did not expect crucial scientific information relating to the scientific content of the post at that stage. So I also missed the vital explanation of how you got temperature from CERES and was under the mistaken impression that was a data field provided by the CERES folks, not a home spun derivation. I will now delete the graph I just saved.
Please be clearer, preferably in the intro when doing that kind of thing.
Many thanks to Dr Spencer for drawing attention to that.

AFAIK neither do any of the other temperature data sets. I think what Willis meant to show was that the temps represented in those data sets didn’t vary much from the CERES data, not that they were accurate measurements of temps.

“The comment was about how dreadful your work is…”
Actually it merely implied you didn’t value his input – which could imply either you have a personal problem with Willis or you do not value his work.
I greatly enjoy his input – he is always taking viewpoints I find interesting – more than I can say about most “Attackers” who add nothing of value to the conversation. Take a moment to actually read the article and say something interesting next time. Plz.
Meanwhile…I find the heating of the northern pole to be very curious. I never put any trust into the “land temperature measurements” up there since they are so sparse, but the satellite record seems to be indicating something weird is going on. If this were due to the influence of either the sun or cosmic rays, wouldn’t both poles be affected? Makes me wonder if there isn’t an unnamed oscillation between the poles that we are just now noticing. How the heck would that work?

Robert of Texas, one view of why the Arctic is warming is the positive phase of the AMO. Warmer water flowing into the Arctic through the N. Atlantic has melted more ice which in turn allows more heat to enter the atmosphere from the ocean.
Since the AMO has little influence in Antarctica you would not see the same effect. However, having more ice melting in the Arctic could very well speed up the Meridianal Overturning Current (global ocean current) which could lead to more upwelling of cold water around Antarctica.
This would cover two of areas of interest. Finally, increasing CO2 could actually be responsible for the warming of the desert areas and the cooling of the tropical rain-forests. This is an expected result of of Dr. William Gray’s alternate water vapor feedback hypothesis.

Willis, he was not “attacking a man” he was saying he did not wish to read your work. That is presumably based on past experience of reading your work, not a personal “attack”.
There are similarly several commenters here like HenryP that I don’t even bother reading any more because they are so irrelevant. It is perfectly valid to form an opinion about someone’s work based on their past work and use that as a filter.
I have a positive prejudice in your case because your posts are often interesting and ( usually ) clearly explain the origin and processing of the data.

There was a study done years ago that examined reading and comprehension levels of American citizens that suggested they read on a fifth grade level and comprehend on a third grade level. Perhaps that extends to a small minority of WUWT participants. In reading Willis’ posts over the years I have been enriched by his presentations, since as a chemical engineer, I’m not a member of this exclusive community. Since I suffer from Expressive Aphasia from three strokes(no sympathy please)–my affliction requires re-reads in order to process the information, and hopefully comprehend what is presented.
This chest puffing and ad hominem attack does not offer any value to what we are all hear for—mainly to offer theories and evidence to promote knowledge. Can we provide the respect to each other that the other side does not?

Anthony, that is exactly what I was thinking by the time I got to the 5th ad hom by Bradley. I started skipping because of my experience with his earlier junk comments.
Fortunately each comment has a bolded “Rob Bradley” at the top left informing me that it is time to flick the wheel (I have one of those mice with a no-click centre wheel – makes for faster fly-bys). It is the ultimate in efficient no-click browsing.
Willis: Thanks for the charts. I want to cite them in Atlanta in August. At best, CO2 might promote some regional warming, but it is certainly not global. It can be argued that is it sub-regional at best. It is also sub-annual because it is only in winter that one can trace some upward evidence.

March 24, 2018 6:04 pm

B.j., I agree that it has to somewhat to do with clouds. Dr. William Gray believed that adding more CO2 will lead to higher evaporation (caused by increased downwelling IR) which will work as a negative feedback. This would occur over rain-forests but not over deserts. Hence, the deserts would warm while the rain-forests could very well cool due to a strong negative feedback (clouds and reduced high altitude water vapor).

Reply to  B.j.
March 24, 2018 11:49 pm

And as Dr Spencer pointed out the way W. has derived the “temperature” data probably is being biased by cloud cover problems with the coverage in CERES data. This is not CERES temperature data produced and endorsed by those running the project, it is Willis’ homespun, non PR “temperature” data.
If CERES allowed a reliable temperature field to be calculated I would expect the CERES guys to be marketing it.

“The third pattern period starts in 1178 AD, and is caused by a strong cosmic lunar meteor impact. At this date, this impact displaced the Earth-Moon Barycenter (EMB), which then spirals back in 4 complete loops onto its regular EMB flight path around the Sun”

Many claims, no proofs.
“caused by a strong cosmic lunar meteor impact”
Exactly how is this impact, to the moon, determined and proven?
“this impact displaced the Earth-Moon Barycenter (EMB)”
Exactly how is this claim and effect determined?
“which then spirals back in 4 complete loops onto its regular EMB flight path around the Sun”
Just how does that mechanism work? For every action there is inaction? That four loops bit of description smacks of a model. not empirical evidence.
Before that odd Earth-Moon-Sun physics, I have no clue exactly what you are describing:
• A) Are you describing the Earth-Moon orbit around the sun, as the sun orbits within the Milky Way Galaxy?
• B) Or are you only referring to Earth’s orbit, around the sun as it orbits the Milky Way Galaxy?
• C) Or are you referring to Earth’s moon orbit path around Earth, around the sun as the sun orbits within the Milky Way Galaxy.
All of which fail to explain why Earth’s moon meteor impacts and orbit has any impact to Earth temperatures?

Reply to  Willis Eschenbach
March 24, 2018 6:54 pm

I’d love to know the mechanism by which a barycenter can be displaced.
The only way’s I can think of would be for either the orbit of the moon to be substantially changed or for the mass of either the earth or the moon to be changed substantially.
In neither case would the barycenter spiral back to what it used to be.

Not commenting on the merits or lack thereof of J.’s hypotheses, but 1000 years is not a long time in climate studies. The longer the period of observation, the better. A millennium is shorter than many climatic cycles.
The peak of the Medieval Warm Period, of which CACA advocates wanted so much to get rid, was about 1000 years ago.

It looks like using a bunch of sin waves to match a curve… I don’t understand how that explains the climate changes, but instead seems to just model them.
You prediction is that it should continue to warm, or at least not to cool until 2049 (+/- some error margin?). The problem with these kind of predictions is that I will be dead before I know the answer… 🙁 Its easy to make claims that are far into the future – no one will remember if you are wrong – this is a common tactic used by the AGW crowd (or whatever they call their religion these days). To have any immediate value you need to make some predictions that can be measured in a few years (10 or less would be nice).
I have been following some people’s prediction that due to the solar activity, we will be entering a period of cooling somewhere in the early 2020’s. If it does show any degree of cooling for several years, this would be proof that your hypothesis failed?

Willis, plz explain for mere mortals like myself… LOL Why is the CERES data data statistically significant for one and not the other? You say these things which are opportunities for me to learn, and then just leave me hanging! 🙂

Peter Sable
Reply to  Willis Eschenbach
March 24, 2018 5:43 pm

So the answer basically is, significance depends on the size of the trend and the length of the dataset. (The other factor is the “Hurst Exponent” of the dataset, but that’s getting down into the weeds

It’s not just the Hurst exponent, it’s whether there are also external factors driving a system that have periods longer than the window of the data you are looking at (well, really longer than the window divided by a factor of 2-5 depending).
For example we have about two datapoints for the 60-70 year PDO/AMO cycles (140 years of temperature and other PDO related data). We don’t know much that’s statistically significant given a sample size of 2. We just know they seem to exist.
That’s why I dislike trendlines on time series data. There’s a huge assumption about oscillations whose periods are longer than that of the dataset. Those oscillations that are long look like trends… but they are not.
And from a scientific philosophy standpoint, you have to prove they are NOT there, not the reverse. (aka the null hypothesis). Very difficult to do, we only have very poor proxies (which have hints of long periods…)
Which means getting back to one of your favorite and my favorite quotes: “I don’t know” applies to trendlines in time-series data.

Trenberth Travesty seen from space

The centrepiece of Nature’s April cover story is a stunning panorama of the Trenberth Travesty, stitched together from satellite imagery of the famous “missing” thermal energy.
“Using the hermeneutics of quantum gravity,” report the authors, “we are at last able to visualize this tricksy, mercurial zone of heat exchange whose 20,000-km front stretches from Cape Illusionment in autumn to The Isle of Mann in fall.”
The latest scientists believe the Travesty acts by thermal subterfuge to “launder” Kelvins from the atmosphere all the way down to the bathyclimatic ecosystem of the ocean floor, converting them to Hiroshimas en route.

Yes l agree its a positive feedback.
l just don’t agree with the warmists claim that its been due to CO2 levels. Far more likely its been due to changes in wind patterns. With increases in warmer southern winds and a decrease of Polar air flowing over the area.

lf you look at the Rutgers Spring Eurasian snow extent chart, you will see there has been a decline in the snow extent over the last 50 years.
Why is northern Russia warming and not northern Canada?
Well there has been warming in northern Canada, its just not as much as in northern Russia.
Again the spring snow extent has a likely answer. Because if you look at the Rutgers N America spring snow extent. You can see the decline in spring snow extent in N America has been less then in Eurasian over the last 50 years.
So less of a decline in spring snow cover in N America means less of a positive feedback for that area as well.

l still believe that spring snow extent is more of a factor then its been given credit for.
Took a look at the data on Rutgers and its noticeable that the biggest declines in the snow extent since 2000 have been in late spring/early summer. Just when it matters the most. lts also interesting how the spring of 2017 bucked that trend and its looking like this spring may also do the same. So l will be looking to see the changes if any it brings to temps in northern Russia.

Hi Willis,
When do you expect your thermoregulatory system to start working? The top figure gives a temperature increase of 0.1 degrees per decade. Which given a few years will exceed your stated limits of +/- 0.2 degrees? Or is your claim that over any 20 year period the temperature will remain within a 0.2 degree limit
– a position completely consistent with global warming allowing you be right while raising CO2 levels continue to cause the temperature to increase.
Do you want to claim that over a 40 year period the trend will be zero? Or is there a measureable trend over a 40 year period?

Reply to  Germonio
March 24, 2018 2:37 pm

Since Earth has probably warmed only about 0.5 degree C since the end of the LIA (rather than the cooked book figure of 0.8 degree often cited), the trend for that period is around 0.03 degree per decade.
As with all previous warm intervals during the Holocene, the Modern Warm Period has contained cooling cycles as well as warming. Each lasts about 30 years. The warming from c. 1977, when the PDO flipped, until the past decade has been no different from prior instances, the early 20th century and mid-19th century warmings, separated by cooling cycles. The world is already cooling again, although the El Niño of 2016 obscured its effect.
Arctic sea ice, for instance, has been growing since 2012. When the AMO enters its cool phase in a few years, the effect should become more pronounced.

Warming periods in the 1880s, 1930s-1950, and 1990s-2017 that are interspersed with cooling periods.
Your claim for greater warmth is evanescent.
Willis has demonstrated CERES data for the period from 2000-2017, which everyone basically agrees was a warming period.

No, it hasn’t. In 1995, even alarmists agreed on 0.5 degree C. Since there has been essentially no warming since then, and that figure was probably high, the real number is around that level.
The traditional end of the LIA is given as 1850, but dates before and after that year have been suggested for the first warming cycle of the Modern WP. Earth cooled dramatically from the 1940s to late ’70s, as it also did in the decades before WWI.

As nearly as I can reconstruct them from spotty raw data, here is my take on the alternating warm and cool cycles of the secular Modern Warming interval:
W: 1857-87
C: 1888-1917
W: 1918-44
C: 1945-76
W: 1977-2006
C: 2007-
The early 20th century warming was probably hotter than the late 20th to early 21st century interval. So far the Modern Warming has been cooler than the Medieval, which was cooler than the Roman, which was cooler than the Minoan, which was probably cooler than Holocene Climatic Optimum peak warmth.
Previous secular warm and cool periods of the Holocene and prior interglacials show similar countertrend cycles.

It is the slow drifts that make your hypothesis almost completely unfalsifiable and so non-scientific. Your claim seems to be that there is thermoregulation except for when there isn’t (i.e. the slow drifts) and for unknown reasons. How does one prove that such an assertion is wrong? Over the last twenty years the CERES data present above suggest the temperature is rising at a rate of 0.1 degree per decade. Is that a slow drift? Or a rapid one on a geological timescale?

Reply to  Willis Eschenbach

if a car continued to increase its speed by 1% per kilometre while on cruise control at which point would you say that they cruise control was not working? The same with a “slow drift” idea at which point does the slow drift mean that the supposed thermoregulation is not working?
Nobody disputes the existence of positive and negative feedbacks in the climate system. The question is whether there are sufficient negative feedbacks to overcome the positive effects of increasing CO2. I would dispute that your thermoregulation effect is strong enough to counteract the effects of changing CO2 levels. Suppose for a moment that all CO2 and other non-condensing greenhouse gases disappeared from the atmosphere overnight. What would be the effect on the temperature? The standard greenhouse gas theory would predict that in a few weeks all of the
water vapour in the atmosphere would condense out and the earth would freeze. Would your
thermoregulation effects be strong enough to prevent that?

Reply to  Willis Eschenbach

The GHE of CO2 is practically played out after the first 200 ppm. The effect is logarithmic, so adding more is, as Lindzen says, like putting another coat of white paint on an already white wall.
The net feedback effects are liable to be negative on a homeostatic, water world. Hence ECS is likely to be less than 1.2 degrees C per doubling. But even if slightly positive, net net, ECS would come in between 1.2 and 2.0 degrees C, probably around 1.6.
So, no worries. It’s all good.

Reply to  Willis Eschenbach
March 24, 2018 5:18 pm

I didn’t say that there was “saturation” above 200 ppm, but that most of the GHE of CO2 has already been effected at that level, due to the logarithmic nature of the GHE. The molecules continue working, but with diminishing returns.

The most common example of a governed system in our lives is the “cruise control” on your car. Does it hold your speed perfectly steady? Of course not. I set it for 60 mph, and as I drive around it varies up or down by around 3 MPH.

Actually no! More people do not live in Russia than before. I don’t generally trust Wiki but it will suffice in this case.
“Low birth rates and abnormally high death rates caused Russia’s population to decline at a 0.5% annual rate, or about 750,000 to 800,000 people per year from the mid-1990s to the mid-2000s.

Your legend “Deg C/Cent” translates as “Degree Celsius/Centrigrade”.
Not that one can tell exactly what “red” equals, since at 2.5°C the color is yellowish orange. Plus, it looks like the scale is increasing since the distance from 2.0°C to 2.5°C is much smaller than the scale at lower temperatures.
CERES during a warming period runs at 1.2°C.
Once several periods of cooling and warming are properly tracked, there may finally be an accurate rate °C per century.
Way over 2.5°C per Century? Extremely doubtful.
Your graphic states GHCN V3 and ERSST, I simply copied what you listed.
Nor does your answer unequically state that there is not any infilling.
Does that claim of yours “the trends of the stations as marked”, mean you downloaded the station data from the stations?
Or is it the data as entered into the GHCN V3 system by NOAA/NASA

Methods for removing inhomogeneities from the data record associated with non-climatic influences such as changes in instrumentation, station environment, and observing practices that occur over time were also included in the version 2 release (Peterson and Easterling, 1994; Easterling and Peterson 1995). Since that time efforts have focused on continued improvements in dataset development methods including new quality control processes and advanced techniques for removing data inhomogeneities (Menne and Williams, 2009)”

Both historical and near-real-time GHCN data undergo rigorous quality assurance reviews. These reviews include preprocessing checks on source data, time series checks that identify spurious changes in the mean and variance, spatial comparisons that verify the accuracy of the climatological mean and the seasonal cycle, and neighbor checks that identify outliers from both a serial and a spatial perspective”

It does not appear that “unadjusted” means what you think it means.

I used the GHCN V3 tabulation. For these years, that comes directly from the CLIMAT forms, as submitted by the met offices and displayed here.
“It does not appear that “unadjusted” means what you think it means.”
I know very well what it means. I have extensive experience with the set and its errors, as described here. It is unadjusted. Values thought doubtful are flagged, not removed or altered, no matter how ridiculous. Errors are often dramatic, like a sign or decimal point error. In my own work, as here, I removed all quality flagged readings. That is my choice. They are a very small percentage. Details for 2010-2014 with all flagged stations are in that link. There are in total 1101 flagged data (listed in detail) in 53 months, out of about 2000 stations per month.
“Not that one can tell exactly what “red” equals”
If you go to the app, you can click on any station to get name and trend, in numbers. The color scale has to be non-linear, otherwise most of the color range goes to separating the extremes.

There’s only so many Joules to go around and for one region to cool, another must warm. As for why the N preferentially warms while the S preferentially cools, this could be an artifact of the S receiving more solar energy than the N owing to the alignment of precession with the seasons and/or the relative ratio of land to water between hemispheres.

So upward radiation increased near the N pole and decreased around the southern ocean, perhaps because of changes in the frequency and duration of cloud cover? Perhaps because of changes in heat carried to and above the Cloud Condensation Level? Something else? That’s something, but I don’t see it having any straightforward implication. It reads like the start of an investigation, where you confirm that you can download, manipulate, and graph data. If it’s real, and your analysis suggests that it is, then it is worth pursuing.

March 24, 2018 7:33 pm

Willis writes, “what is of note in these global maps? Well, both the poles are unusual.”
I think an important part of the difference between the two poles is because of the north polar and south polar snow and ice albedo differences. The south polar snow and ice is pristine. The northern is covered with a very fine layer of soot, sometimes more.
The melting from the soot albedo change causes additional albedo change and warming, a positive feedback. Look at the photographs of Greenland dirty ice and snow.-

How does this jive with temp profiles for the Arctic which show virtually all warming during the winter season, when there is no insolation to be absorbed by any soot. Might melt some snow/ice during high sun, but obviously has little effect on summer temps.

The Canadian Government has relocated nearly all Arctic temperature sensors to Airports since the 1990s, the manned remote stations are all closed.
These airstrips are all now paved, most were still gravel not too long ago.
Yellowknife Airport just relocated the weather station to the wind shadow of the terminal building and surrounded it with black dirt.
I am sure this station will show unusual warming, especially last summer when the dirt had no vegetation.
But being now sheltered from the prevailing wind, I expect to see another “unprecedented” Arctic temperature increase recorded by this station.

Pretty much the same likely for ocean oscillations like ENSO and multi-decadal ones if indeed they are oscillations that over time establish their own natural time delays, for instance living near the Pacific Ocean the coldest month is February about 2 months beyond the least sun. About the same thing at the other end in June max sun, August max temperature. As regular as those changes are why would we expect a bump in the anomaly that we don’t already see?

Nor is this due to “thermal inertia” as many people claim.
The one thing that has troubled me for decade. It is obvious to any observer that there is very little inertia. Yes, the ENSO leaves a ‘taste in the mouth’ for more than a year and an SSW appears to create an atmospheric image for a few months. so What causes ice ages? What is it that changes the global temperature by 3 to 5 °C and holds it while glaciers SLOWLY build.
Thanks Willis. Great post again.

Its pretty clear to me that you could probably tune an ice and ocean inertia model to explain the approximate 2 to 3 degrees warming since the end of the Maunder Minimum in approximately 1700 using global glacial ice change and an ocean uptake (inertia) model. Some of the longterm instrument records show a rapid warming occurring in a few decades after the Maunder Minimum, this could be a rapid warming of the surface ocean that reduced low latitude and low elevation ice. The warming then flattened until interrupted temporarily for a short period by the Dalton Minimum. After brief recovery post 1815 temp increases from the LIA (500 years of cooling) then another flattening to the mid 19th century during which period global glaciers continued to increase and increase surface albedo. Then in the mid-19th century glacial advance reversed into retreat allowing climate warming to dominate from the underlying ocean inertia. The 500 years of cooling from 1200 to 1700 could take as long to reverse back out with the same intensity things cooled and drove the Vikings out of Greenland from glacial advance as far back as 1300 to 1400 from the more distant settlements. That would put on a model the warmed as fast as it cooled warming from ocean inertia until 2200. Its hard to put values on it lacking early temperature records from the Medieval Warm Period but today they are assumed to be comparable by some studies to day plus or minus a degree or so. The only criticism of the idea of an extended LIA recovery was the flat period from the mid part of the first half of the 18th century until the mid 19th century. So an explanation is needed for that and glacial advance and retreat data overlies it very nicely chronologically. All thats left to do is argue the actual degree effects which can probably be tuned in quite nicely. Of course even today we are not measuring what it happening in the lower 3/4ths of the ocean so as one study put it we are probably today a 1,000 years or more away from a data record that would demonstrate that.

A bit off-topic, probably: In 1950, world population was about 2.5 bn. In 2018 the population has risen to 7.5 bn. The average body temperature is 36.5 to 37.2° C. Today, there are 5 bn people more on this little planet that heat it up. “AGW” is said to be on the rise. Is there a correlation or even a causation?

Dear Willis, “Despite being controlled by things as evanescent as winds, waves, and clouds, the temperature anomaly doesn’t vary more than about two-tenths of a degree.” Given the stable climate conditions, it may be better to state: Because being controlled by things…… As nature is regulated by chaotic processes from molecular level up, averaging each other in impact, the end result. the macro world as we experience it, must nearly by definition be rather stable; variations with 0.2 – 0.3 degrees.

March 25, 2018 2:41 am

As I’ve been saying, Tmin is regulated on the cooling side at night to limit how cold it gets by water vapor, just as W found a relationship with max ssts, and day time T max.

March 25, 2018 4:23 am

As usual, the strongest variations happen in places where the data is lacking the most. Heavy interpolation going on. Still, the cooling shown for the southern oceans contradicts the rapid melting of ice caps shown by satellite pictures for the kerguelen islands for example. But the rapid melting can also be explained by weather factors.

Don’t forget to add that increasing the CO2 concentration increases the emissivity of the atmosphere.
It is interesting that back radiation gets frequent mention but not the ‘greyness’ of the body of the atmosphere. Without GHG’s, the atmosphere couldn’t cool by radiation at all. It would be heated by the surface and stay that way.
A desert that has higher temperatures could just have lower humidity and the same energy input. The enthalpy (total energy) in the atmosphere above the desert is the correct number to watch. I realise it is fashionable to talk of temperatures only, but that is a technically not how to think about energy gain and retention (etc). Equally, the Amazon could be cooler simply by having a higher average humidity, not a lower energy input or higher emittance.

Polar see-saw
From Wikipedia, the free encyclopedia
The polar see-saw (also: Bipolar seesaw) is the phenomenon that temperature changes in the northern and southern hemispheres may be out of phase. The hypothesis states that large changes, for example when the glaciers are intensely growing or depleting, in the formation of ocean bottom water in both poles take a long time to exert their effect in the other hemisphere. Estimates of the period of delay vary, one typical estimate is 1500 years. This is usually studied in the context of ice-cores taken from Antarctica and Greenland.

And glaciers in that region are growing, both from more precipitation and cooler temperatures. So much for the IPCC’s ill-founded prediction of glacier disappearance.
On balance, the whole world has been cooling for about a decade, a fact obscured by the big ENSO swing of 2016, which blew off a lot of oceanic heat, thus contributing to further future cooling.

Unlike the Mother Jones use of the photography of Greenland’s dirty ice and snow to promote “worry” and activism to reduce CO2 emissions, I think the northern polar dirty ice and snow is an example of significant AGW, a first order forcing, unrelated to the GHG first order forcing. With the great percentage of land in the northern hemisphere and even greater percentage of industry, we’ve changed the albedo and melt rate in the northern polar area, but not the south.
In addition to the albedo change, when ocean ice melts, exposing the darker water, there may also be additional second order surface changes. Polar water seldom warms much above 32 F degrees as extra heat energy melts ice before raising water temperatures. Therefore, I hypothesize that areas of soot covering snow and ice may often be the warmest north polar surface areas with melting and sublimation below the areas of soot. Surface areas that are warmer than surrounding areas are areas of low pressure because warm air rises. Wind occurs because of pressure differentials. If my hypothesis is correct, then changes in surface pressure and winds (and therefore weather patterns) result from the dirty snow and ice you see pictured here-

Not to mention a whole fleet of Russian Ice Breakers that are busting up the Siberian northern Arctic Ocean on an annual basis now for the last 30+ years, which causes it to melt quicker every summer. There are a lot of ‘additive’ processes that humans are introducing to the natural environment over and above CO2 that get barley no mention. Especially in the Northern Hemisphere where the majority of humans and industrial activity is, with a much larger land mass at near sea level, Greenland notwithstanding.

I like to have a close look at the graphed data before they are transformed and I notice that the variations in the cold season lowest temperature is larger than the variations in the higher. Perhaps it indicates the presence of a thermostat. I don’t know.
But the view that a the resulting anomaly should indicate hotter weather on the hottest days need to be questioned.

“So … what is of note in these global maps? Well, both the poles are unusual. The area around Antarctica is cooling strongly, and the Arctic is warming. Presumably, this is why we’re getting less sea ice in the North and more sea ice in the South. It also affects the hemispheric averages, with the Northern Hemisphere warming and the Southern Hemisphere basically unchanging.”
The Earth spends less time near perihelion and more time near aphelion. This means that the lengths of the seasons vary. Perihelion currently occurs around January 3, so the Earth’s greater velocity shortens winter and autumn in the northern hemisphere. Summer in the northern hemisphere is 4.66 days longer than winter, and spring is 2.9 days longer than autumn. And correspondingly the same less in the Southern Hemisphere, meaning 7+ more days of fall and winter in SH. In Antarctica, where it is a high elevation continent covered in perpetual ice, (unchanging Albedo) surrounded by the southern ocean that rapidly gains ice every SH winter, therefore self reinforcing on an annual basis.
Obviously, present day orbital mechanics govern this as Kepler’s second law states, but when natural variation is cold, such as the LIA, then it is mostly frozen over and Albedo is reflecting incoming insolation and little warming to be had, but when things warm naturally, or with assistance from human kind in many industrial ways the last 150 years, then less Albedo as more ice melts leading to earlier springs and less time in NH snow cover. And given most of the NH Arctic is closer to sea level (Greenland notwithstanding) as is a majority of the land in the NH, and additional to humankind industrial inputs, then it is only logical that the NH is more sensitive to to solar and human forcing, than the SH.
This is part of the obvious reason why the Northern Hemisphere is warming and the Southern Hemisphere basically unchanging. There are dozen’s of other natural processes going on, but I think this explains why more current Northern Hemisphere warming presently, and why we have registered net warming the last 150 years because sensitivity to warmer is presently much greater in the NH than the SH.

Willis wrote: “As you can see, the only parts of the planet where the temperature is changing much are the Southern Ocean around Antarctica, and the area above the Arctic Circle” .. Go Figure.
Interestingly, the Arctic and Antarctic are both linked through downwelling into the deep ocean. If total downwelling were limited by the requirement that the sum matches total upwelling, then a slowing of downwelling in the Antarctic would be accompanied by a increase in downwelling in the Arctic. Increased downwelling in the Arctic would lead to import of more warm water from temperature regions on the surface and Arctic warming. Decreased downwelling in the Antarctic would lead to less import of warm water and cooling.
IIRC, a see-saw of this sort has been hypothesized to function during the very warm periods (+10? degC) observed in Greenland ice cores (and Antarctic ice cores) during the last ice age. Likewise, warming took place much earlier in Antarctica than Greenland as the last ice age ended.
When looking for a reference, I found that Chylek has made some of the same observations you report here, except he covers the whole 20th century.

Willis, you are aware that in climate science some major importent variables are missing and that the IPCC list with internal variables is uncomplete…. and there must be some other external forcing which governs our climate and explains the about 400 year long climate movement up and down: CWP – LIA – MWP – LALIA – RWP – Greek cold…..etc. This about 400 year climate wave up and down is historical knowledge (before your time) of the Old Greeks, There exist a preserved letter of Solon in Greece to the Pharao (300 BC), in which he described this multi-centennial observation and this, temp/climate up and down continued after Solon, see the above described climate up and down……. The regularity of this centennial movement points to external causes, which are not the Sunspots, but rather Earth Orbital Changes. For this reason, the climate came out of the deep, cold LIA in the 17 Cty and will peak (at 2048-49) in the 21st century, continuing this up- and down cycle……this is the message of my paper Holocene part 8, which you are unwilling to read.
I call this attitude LEARNRESISTENT. Especially you know NOTHING about the osculating, oscillating, “perturbating” Earth orbit around the Sun, which is the cause for this centennial climate change…..
Instead, you walk in circles, over and over getting stuck in the IPCC nonsensical internal “climate causes” and falsifying what is false to recognize without computer check…..
You are victim of the IPCC AR4 ploy in 2006 to point to 20,000 + -year Milankovitch exclusively and thus aiming at COVERING UP of ALL annual. decadal and centennial Earth orbital changes….. and you are a stout believer of IPCC nonsensical ploy. Climate relevant are the OSCULATIONS, (Oscillations, Perturbations) of the Earth orbit. ….and you reject to look into the matter, because you are a true victim of the ploy and my booklet would be over your head anyway, this is, what you feel…..but it is written with extra care for the normal citizen without previous Earth orbital knowledge.
I had a fruitful Email exchange with the Milankovitch coryphea Andre Berger (Louvain Uni), who ADMITTED the oscillations, even ordered my booklet, but we could not get further, becaus JPL Pasadena, close to you where you live, keep the (I believe as part of Hanson NASA GISS) – or other reasons, the astrophysical Osculation values of the Earth Orbit.SECRET…. (I resorted to good historical measurements). If you were able to get those osculation distances, place the distance variations between Sun and Earth in a forcing system of x Watts/1 million km perturbation (as in my booklet) then you will get the temp increase out of the LIA into the present CWP. you will recognize the temp max in 2048-49 AD….
But you rather prisoner in you circle of dwelling in internal IPCC forcings and leave all the WUWT readers in limbo, why global temps increase, stay flat, go down and you then you WONDER HOW global temps continue after the present plateau…and admit not being able to make a senseful forcast as I did in part 8, based on sound physical astrophysical values, continuing the work of Newton, Gauss and Leibnitz, which you are unwilling to accept.

“…A spiral is a shape which winds round and round, with each curve above or outside the previous one…”
If a cataclysmic impact of some object with the Moon or Earth were to change their orbits, their orbits would stay changed. They would not spiral back to their old orbits.

to Dave Burton: Dave, lets stop the conversation…..You are a high school student, trying
to look smart…….. you need to read about the Earth orbit and how gravitational forces act
onto Earth, Moon and planets. Cheers Js.

Dave Burton is right. It goes back to Kepler that orbits are ellipses (or more generally conic sections). Newton explained why. A spiral is not a conic section.

Equatorial “tropical forests cooling”….
I’ve talked about this before. I suspect greening of the planet makes some contribution to cooling. It is an endothermic process and it coincided with the “pause”. In 2012 forest cover expanded 14% in 30 yrs and is ongoing. I recall reading that earths trees number 3 trillion, i.e. 14% means 420B new trees avg ~ 15yrs old, some 200kg/tree carbon sequestered or~80GT in 30 yrs, say by 2018 100GT Carb. Assuming “heat” sequestered equivalent to 120% that amount of anthracite energy content (40GJ/MT)~4TJ.
It is a remarkable fact that this greening, the only climate change thats unequivocal, gets scant mention by the science. Of course this absolute proof of real climate change comes at a cost- the greening (doubled harvests, increased habitat, conservation of water and diversity) makes carbon emissions a huge net benefit rather than a cost. We would perhaps owe a premium to the fossil fuel industry! If the math is correct, it is conservative because, to my mind, the greening would be exponential.

You are right in that photosynthesis is the blind spot of climate. “Earth energy budget” is wrong on this one.
FAO ( http://www.fao.org/docrep/w7241e/w7241e06.htm#TopOfPage ) use a 2 kg CO2 ~ 30 MJ, that’s 55 MJ / kg C, so 100 Gt C would be ~ 5.5TJ. Your estimate (100 Gt C) seems correct, provided you don’t mean just live trees, as most of them are now dead and slowly decaying in the soil.
Because :
carbon cycle estimates (official science, so to speak) are that, roughly, of all anthropogenic carbon (~350 Gt as of now)
* ~45% is still in the atmosphere
* ~1/3 has been turned into plants, part still alive, most now dead in the soil.
* ~1/5 sunk down the oceans
Of the ~120 Gt turned into plants, most of it is now dead in the soil, slowly decaying. Then again, we can estimate the still living part as per the “consensus climate science”, which says that anthropogenic contribution is an increase of 3 Gt uptake (123 Gt instead of 120 Gt), which is 2.5%, and 2.5% of 550 Gt plants is ~14 Gt.

Willis Eschenbach sez:
“In my opinion, the most important words
that anyone studying the climate
can learn to say are “I don’t know.” ”
My comment:
In my opinion,
that true statement
moves Willis Eschenbach
up one notch, from a
good writer of scientific articles,
to a great writer.
In my opinion,
the highest possible level
of knowledge in climate science
is self awareness (“I don’t know”),
coupled with the ability to refute the
IPCC’s “CO2 controls the climate”,
and will cause runaway warming,
which is just wild guess speculation.
Mr. Eschenbach has reached the highest level.
Some people who can refute the IPCC conclusions
think they have to provide a better conclusion
about climate change — their own theory,
and often their own climate prediction too.
But it is easier just to refute the IPCC,
without claiming you have a better theory,
and a better prediction of the future climate,
because your theory and prediction are very
likely to be proven wrong.
“Modern” climate science is based
on a prediction of the future climate,
that we are supposed to believe
because it is stated with great confidence
by government bureaucrats
and politicians
year after year …
in spite of them providing
30 years of wrong climate predictions,
as strong evidence the future climate
can’t be predicted, other than saying
“It will change”.
