Contrary to expectations, climate scientists continue to report that large regions of the Earth have not been warming in recent decades.
According to Dieng et al. (2017), for example, the global oceans underwent a slowdown, a pause, or even a slight cooling trend during 2003 to 2013. This undermines expectations from climate models which presume the increase in radiative forcing from human CO2 emissions should substantially increase ocean temperatures.
The authors indicate that the recent trends in ocean temperatures “may just reflect a 60-year natural cycle“, the AMO (Atlantic Multidecadal Oscillation), and not follow radiative forcing trends.
Dieng et al., 2017 We investigate the global mean and regional change of sea surface and land surface temperature over 2003–2013, using a large number of different data sets, and compare with changes observed over the past few decades (starting in 1950). … While confirming cooling of eastern tropical Pacific during the last decade as reported in several recent studies, our results show that the reduced rate of change of the 2003–2013 time span is a global phenomenon. GMST short-term trends since 1950 computed over successive 11-year windows with 1-year overlap show important decadal variability that highly correlates with 11-year trends of the Atlantic Multidecadal Oscillation index. The GMST 11-year trend distribution is well fitted by a Gaussian function, confirming an unforced origin related to internal climate variability.
We evaluate the time derivative of full-depth ocean heat content to determine the planetary energy imbalance with different approaches: in situ measurements, ocean reanalysis and global sea level budget. For 2003–2013, it amounts to 0.5 +/− 0.1 W m−2, 0.68 +/− 0.1 W m−2 and 0.65 +/− 0.1 W m−2, respectively for the three approaches. Although the uncertainty is quite large because of considerable errors in the climate sensitivity parameter, we find no evidence of decrease in net radiative forcing in the recent years, but rather an increase compared to the previous decades.
We can note that the correlation between GMST [global mean surface temperature] trends and AMO trends is quite high. It amounts 0.88 over the whole time span. At the beginning of the record, the correlation with PDO trends is also high (equal to 0.8) but breaks down after the mid-1980s. The GMST and AMO trends shown in Figure 6 show a low in the 1960s and high in the 1990s, suggestive of a 60-year oscillation, as reported for the global mean sea level by Chambers et al. (2012). Thus the observed temporal evolution of the GMST [global mean surface temperature] trends may just reflect a 60-year natural cycle driven by the AMO.
Subpolar North Atlantic Cooling Rapidly Since 2005
According to Piecuch et al. (2017) there has been no net warming of the North Atlantic Ocean in the last quarter century. The warming that occurred in the 10 years from 1994-2004 has been completely negated by an even more pronounced cooling trend since 2005. The predominant (87%) cause of the warming was determined to be of the same natural (non-anthropogenic) origin as the subsequent cooling: advection, the movement/circulation of heat via internal processes. In fact, human CO2 emissions are never mentioned as even contributing to the the 1994-2004 warming.
Piecuch et al., 2017 The subpolar North Atlantic (SPNA) is subject to strong decadal variability, with implications for surface climate and its predictability. In 2004–2005, SPNA decadal upper ocean and sea-surface temperature trends reversed from warming during 1994–2004 to cooling over 2005–2015. … Over the last two decades, the SPNA has undergone a pronounced climate shift. Decadal OHC and SST trends reversed sign around 2004–2005, with a strong warming seen during 1994–2004 and marked cooling observed over 2005–2015. These trend reversals were pronounced (> 0.1 °C yr−1 in magnitude) in the northeastern North Atlantic (south and west of Iceland) and in the Labrador Sea. … To identify basic processes controlling SPNA thermal variations, we diagnose the SPNA heat budget using ECCOv4. Changes in the heat content of an oceanic control volume can be caused by convergences and divergences of advective, diffusive, and surface heat fluxes within the control volume. [Advective heat convergence] explains 87% of the total [ocean heat content] variance, the former [warming] showing similar decadal behavior to the latter [cooling], increasing over 1994–2004, and decreasing over 2005–2015. … These results demonstrate that the recent SPNA decadal trend reversal was mostly owing to advective convergences by ocean circulation … decadal variability during 1993–2015 is in largest part related to advection by horizontal gyres.
Yeager and Robson (2017) also point out that, like it did from the 1960s to 1980s, the North Atlantic “has again been cooling”, a trend which they and others expect to continue. Sea surface temperatures are no warmer today than they were in the 1950s.
Yeager and Robson, 2017 [W]hile the late twentieth century Atlantic was dominated by NAO-driven THC [thermohaline circulation] variability, other mechanisms may dominate in other time periods. … More recently, the SPNA [sub polar North Atlantic] upper ocean has again been cooling, which is also thought to be related to a slowdown in the THC. A continued near-term cooling of the SPNA has been forecast by a number of prediction systems, with implications for pan-Atlantic climate.
The Southern Ocean Has Been Cooling Since The 1970s, Contrary To Models
Latif et al., 2017 The Southern Ocean featured some remarkable changes during the recent decades. For example, large parts of the Southern Ocean, despite rapidly rising atmospheric greenhouse gas concentrations, depicted a surface cooling since the 1970s, whereas most of the planet has warmed considerably. In contrast, climate models generally simulate Southern Ocean surface warming when driven with observed historical radiative forcing. The mechanisms behind the surface cooling and other prominent changes in the Southern Ocean sector climate during the recent decades, such as expanding sea ice extent, abyssal warming, and CO2 uptake, are still under debate. Observational coverage is sparse, and records are short but rapidly growing, making the Southern Ocean climate system one of the least explored. It is thus difficult to separate current trends from underlying decadal to centennial scale variability.
Turney et al., 2017 Occupying about 14% of the world’s surface, the Southern Ocean plays a fundamental role in ocean and atmosphere circulation, carbon cycling and Antarctic ice-sheet dynamics. … As a result of anomalies in the overlying wind, the surrounding waters are strongly influenced by variations in northward Ekman transport of cold fresh subantarctic surface water and anomalous fluxes of sensible and latent heat at the atmosphere–ocean interface. This has produced a cooling trend since 1979.
Sea Ice Has Been Expanding For The Entire Southern Hemisphere Since The 1970s
Comiso et al., 2017 The Antarctic sea ice extent has been slowly increasing contrary to expected trends due to global warming and results from coupled climate models. After a record high extent in 2012 the extent was even higher in 2014 when the magnitude exceeded 20 × 106 km2 for the first time during the satellite era. … [T]he trend in sea ice cover is strongly influenced by the trend in surface temperature [cooling]. … A case study comparing the record high in 2014 with a relatively low ice extent in 2015 also shows strong sensitivity to changes in surface temperature. The results suggest that the positive trend is a consequence of the spatial variability of global trends in surface temperature and that the ability of current climate models to forecast sea ice trend can be improved through better performance in reproducing observed surface temperatures in the Antarctic region.
The Pacific Ocean Has Also Been Cooling Since The 1970s
Li, 2017 In the Southern Ocean, the increasing trend of the total OHC slowed down and started to decrease from 1980, and it started to increase again after 1995. In the warming context over the whole period [1970-2009], the Pacific was losing heat, especially in the deep water below 1000 m and in the upper layer above 300 m, excluding the surface 20 m layer in which the OHC kept increasing through the time.
Glaciers, Ice Sheets Stable, Even Gaining Mass
Goel et al., 2017 Ice rises are a useful resource to investigate evolution and past climate of the DML coastal region. We investigate Blåskimen Island ice rise, one of the larger isle-type ice rises at the calving front of the intersection of Fimbul and Jelbart Ice Shelves, using geophysical methods. … Using the Input-Output method for a range of parameters and column setups, we conclude that Blåskimen Island has been thickening over the past nine years [2005-2014]. Thickening rates cannot be determined precisely, but ensemble results show that thickening rate averaged over the ice rise varies between 0.07 m a−1 and 0.35 m a−1 [per year]. On longer timescales, we speculate that the summit of Blåskimen Island has been stable within several kilometers at least in the past ∼600 years but no longer than several millennia.
Bader et al., 2017 Rather than reflecting major changes in ice flow path over time, the provenance changes are interpreted to indicate relative stability of the East Antarctic ice sheet.
Martín-Español et al., 2017 We investigate the mass balance of East Antarctica for 2003–2013 using a Bayesian statistical framework. … We apportion mass trends to SMB and ice dynamics for the EAIS, based on two different assumptions, different remote sensing data and two RCMs. In the first experiment, the model apportions about a third of the mass trend to ice dynamics, +17 Gt/yr, and two thirds, +40 Gt yr−1 to SMB, resulting in a total mass trend for the EAIS [East Antarctic Ice Sheet] of +57 ± 20 Gt yr−1.
Bolch et al., 2017 Previous geodetic estimates of mass changes in the Karakoram revealed balanced budgets or a possible slight mass gain since ∼ 2000. Indications of longer-term stability exist but only very few mass budget analyses are available before 2000. Here, based on 1973 Hexagon KH-9, ∼ 2009 ASTER and the SRTM DTM, we show that glaciers in the Hunza River basin (central Karakoram) were on average in balance or showed slight insignificant mass loss within the period ∼ 1973–2009.
Predictions Of Future Cooling, Ice Expansion
Årthun et al., 2017 Statistical regression models show that a significant part of northern climate variability thus can be skillfully predicted up to a decade in advance based on the state of the ocean. Particularly, we predict that Norwegian air temperature will decrease over the coming years, although staying above the long-term (1981–2010) average. Winter Arctic sea ice extent will remain low but with a general increase towards 2020.
Pittard et al., 2017 We suggest the Lambert-Amery glacial system will remain stable, or gain ice mass and mitigate a portion of potential future sea level rise over the next 500 years, with a range of +3.6 to -117.5 mm GMSL-equivalent.

Come on SebastianH- let’s hear the alarmist spin on this.
Not really working out as the models predicted, is it?
Doesn’t look like cooling to me …
https://www.climate.gov/news-features/understanding-climate/state-climate-highlights/2016
Picking out the blue spots and declaring that oceans are cooling is kind of a selective perception, isn’t it?
The authors of the peer-reviewed scientific papers cited in the article do not appear to have gathered their data by gazing at a colorized NOAA graph and then “picking out the blue spots and declaring that oceans are cooling”.
According to the scientists, for example, the North Atlantic OHC has been cooling for the last 10+ years for the same reasons that they warmed for the 10 years before that: natural heat redistribution processes. CO2 is not mentioned as a factor in the 10-year warming or the 10-year cooling. The North Atlantic’s sea surface temperatures are cooler now than they were in the 1950s.
Same with the Southern Ocean, which occupies “about 14% of the world’s surface”. It’s been cooling for 4 decades, which is largely why the sea ice extent has been growing throughout the SH.
Your colorized NOAA map doesn’t show any of this, of course. So does this mean the NOAA graph is right, and scientists publishing papers in peer-reviewed journals are wrong?
Why have the Southern Ocean and Pacific Ocean been cooling for multiple decades, SebastianH? What’s the mechanism? What’s the mechanism that caused the North Atlantic to warm up from 1994 to 2004? Do you believe it was CO2 emissions from humans? Assuming you do, why do you believe that?
Are you again suggesting that the data is fake or manipulated? What makes you so confident to infer that all oceans must be cooling when some spots are? You mentioned natural heat redistribution processes yourself.
You did not answer his question. Are the scientists who are publishing these papers in peer-reviewed journals wrong?
I have not written that “all oceans must be cooling”. Those are your word choices.
The “some spots” you refer to here are apparently in reference to the colorized NOAA graph. The article references several peer-reviewed papers indicating that the North Atlantic, Southern Ocean, and Pacific Ocean have been cooling. The scientists who publish their findings in science journals likely are not getting their info from online colorized temperature graphs from NOAA.
Why have the Southern Ocean and Pacific Ocean been cooling for multiple decades, SebastianH? What’s the mechanism? What’s the mechanism that caused the North Atlantic to warm up from 1994 to 2004? Do you believe it was CO2 emissions from humans? Assuming you do, why do you believe that?
The “colorized NOAA graph” is based on the same data as their data. Are you aware of a new method to measure OHC that nobody has heard of yet and that has been implemented for decades already?
You have not written that, but you are implying it (most likely involuntary).
What is the mechanism for the warming of the rest of the ocean? The first paper is about a pretty small patch of the North Atlantic, are the others about bigger patches? (papers paywalled, can’t check)
Positive forcing = heat content increases until the surface is emitting the same amount of energy as it absorbs again. The emissions can be radiative, evaporation, etc
Parts of the surface can become cooler by other means despite that mechanism.
Why do you think this is a belief? Do you “believe” that you won’t fly of Mars when you jump? Or do you know that because the laws of physics exist?
Look carefully at this link to the NOAA data:
https://realclimatescience.com/wp-content/uploads/2017/02/201612-land-4.gif
This “new method” takes the areas colored gray and white – where no data exists – and infills them with variations of the color red. And then this colorization scheme causes people like you to tout graphs like this as the truth, and to reject papers that show that large regions of the globe have been cooling for decades.
https://realclimatescience.com/wp-content/uploads/2017/01/NOAASept2016.gif
I have not written that “all oceans must be cooling”. Those are your word choices.
No, you don’t get to make up words and claim that I am “implying” saying them either.
http://journals.ametsoc.org/doi/abs/10.1175/JCLI-D-11-00148.1
Global satellite observations show the sea surface temperature (SST) increasing since the 1970s in all ocean basins, while the net air–sea heat flux Q decreases. Over the period 1984–2006 the global changes are 0.28°C in SST and −9.1 W m−2 in Q, giving an effective air–sea coupling coefficient of −32 W m−2 °C−1 …[D]iminished ocean cooling due to vertical ocean processes played an important role in sustaining the observed positive trend in global SST from 1984 through 2006, despite the decrease in global surface heat flux. A similar situation is found in the individual basins, though magnitudes differ. A conclusion is that natural variability, rather than long-term climate change, dominates the SST and heat flux changes over this 23-yr period.
Are we still talking about the heat content?
Here is the data: https://www.nodc.noaa.gov/OC5/3M_HEAT_CONTENT/basin_data.html
Do you think the authors of the papers have a method of measuring heat content different from this one? Did they measure it (over decades) by themselves and nobody else could use their data up until now?
Why the distraction with “land data is fake”?
Six of the first 7 papers reference sea surface temperatures that have been cooling, including the very first one that references GMST. This isn’t just about ocean heat content.
It’s rather telling that you consider it only a “distraction” that the overseer of a long-term global temperature data set (Phil Jones) admits that the SH sea surface temperatures are “mostly made up”. Why are you so confident in the accuracy of temperature data that has been “mostly made up”, SebastianH?
This is getting repetitive …
Where do you think is the data from those papers coming from?
Why are you so confident in the accuracy of temperature data that has been “mostly made up”, SebastianH?
Phil Jones: “For much of the SH between 40 and 60S the normals are mostly made up as there is very little ship data there.”
Yes it is. This is the 5th time you have dodged the question as to what the mechanism is that caused the Pacific and Southern Oceans and the North Atlantic to cool for the past 1 to 4 decades. Obviously you just can’t bring yourself to admit that cooling and warming might be mostly natural.
Seb Isn’t what you have just said the reverse ie just picking out the red spots and say it is warming. Get Real.
You would generally average over the whole volume/area to determine if it is warming or cooling on a global scale.
Do you believe it is false that the North Atlantic, Southern Ocean, and Pacific Ocean have been cooling for the last 1 to 3 decades?
I don’t know … you tell me! Download and graph this data and find out for yourself: https://www.nodc.noaa.gov/OC5/3M_HEAT_CONTENT/basin_data.html
It’s only distinguishing the major basins and NH / SH (so very coarse), but none of the heat content time series show a decreasing trend over the last decades.
And don’t you think that the 45–60°N, 40–15°W rectangle analyzed by the first author/paper you mention is exactly doing what I pointed out? It’s about one of the blue spots and not generally the NH Atlantic ocean. You, however, make it sound like there is large scale cooling going on.
Ok, according to peer-reviewed scientific papers presented in the article, yes, the Southern Ocean (14% of the Earth’s surface), the Pacific Ocean, and the North Atlantic have undergone a cooling trend for the last 1 to 3.5 decades.
NOAA is well known to just in-fill their graphs and data sets with made-up (computer model) temperatures where measurements don’t exist. That’s probably why you prefer their graphs to the data presented in the scientific literature.
You can’t average made up numbers with real ones. If you could, anyone and his brother could get a PhD, which is what seems to have happened, actually.
Please provide the exact areas that were examined in those papers. For the first one (North Atlantic) the area is a very small part of the Atlantic.
So it is “the data is fake anyways” again … how predictable.
Turney et al., 2017 “Occupying about 14% of the world’s surface”…the Southern Ocean has been cooling since 1979.
The first paper presented refers to the “global mean surface temperature” for the sea surfaces, which looks like this:
https://notrickszone.com/wp-content/uploads/2017/09/Global-Ocean-AMO-Temperature-Correlation-1950-to-2014-Dieng-2017.jpg
Beneath the first 2000 meters of the ocean, there has been a cooling for the “entirety” of the Pacific and Indian Oceans and East Atlantic since 1992:
Wunsch and Weinbach, 2014 “A very weak long-term cooling is seen over the bulk of the rest of the ocean below that depth, including the entirety of the Pacific and Indian Oceans, along with the eastern Atlantic basin.”
Why do you think so much of the Earth’s sea surfaces have been cooling in recent decades, SebastianH? What’s the cooling mechanism? Will you at some point be answering this question?
How do you think NOAA fills in the temperature “data” for the areas where there are no measurements? Do you not believe Phil Jones when he tells his colleagues that the SH sea surface temperatures are “mostly made up”?
With “first paper” I mean Duchez et al., 2016
14% of the surface? I raise you to 50% … https://data.nodc.noaa.gov/woa/DATA_ANALYSIS/3M_HEAT_CONTENT/DATA/basin/yearly/h22-w0-700m.dat contains the SH world ocean heat content 0-700 m depth … do you see a decrease? So something must be compensating for the decrease in that 14% part, correct?
Why do you think so much of the Earth’s sea surfaces have been warming in recent decades, Kenneth? What’s the warming mechanism? Will you at some point be answering this question?
Do you think the authors of those papers just happened to have a data source available that hasn’t been used before? The first paper (Duchez et al., 2016) uses the same NODC/NOAA data … what do the paywalled ones use?
I thought we were talking about heat content?
That was the introductory image from a year-old paper. The first paper describes the global mean (sea) surface temperature:
https://notrickszone.com/wp-content/uploads/2017/09/Global-Ocean-AMO-Temperature-Correlation-1950-to-2014-Dieng-2017.jpg
I have responded to this question above already. I’ll do so again here. At what point do you think you might actually describe the mechanism that could account for the cooling? Or will you be continuing to dodge this?
http://journals.ametsoc.org/doi/abs/10.1175/JCLI-D-11-00148.1
Global satellite observations show the sea surface temperature (SST) increasing since the 1970s in all ocean basins, while the net air–sea heat flux Q decreases. Over the period 1984–2006 the global changes are 0.28°C in SST and −9.1 W m−2 in Q, giving an effective air–sea coupling coefficient of −32 W m−2 °C−1 …[D]iminished ocean cooling due to vertical ocean processes played an important role in sustaining the observed positive trend in global SST from 1984 through 2006, despite the decrease in global surface heat flux.

Do you not believe Phil Jones when he tells his colleagues that the SH sea surface temperatures are “mostly made up”?
At what point was it said that we were we only talking about OHC? The very first paper describes the GMST trends for 2003-2013. What does the S stand for, SebastianH?
The second paper on the North Atlantic also indicates that the SSTs have cooled: “In 2004–2005, SPNA decadal upper ocean and sea-surface temperature trends reversed from warming during 1994–2004 to cooling over 2005–2015.”
The third paper (Yeager and Robson) is about sea surface temperatures.
The fourth and fifth papers (Latif et al., 2017 and Turney et al., 2017) both describe sea surface temperatures in the Southern Ocean as cooling.
The sixth paper (Comiso et al., 2017) indicates that the reason why sea ice has been expanding for nearly 4 decades is because of the cooling sea surface temperatures: “[T]he trend in sea ice cover is strongly influenced by the trend in surface temperature.”
It isn’t until the 7th paper listed, Li (2017), that we have a description of OHC-only trends.
So I suspect that you have again began making comments without having actually reading the article, or by operating on your own assumptions of what you think is happening.
Do you think the mechanism for cooling of the sea surface is different from the warming mechanism?
Ok, I’ll rephrase then. I am talking about the heat content. While SST is interesting too, the accumulation of energy is measured as heat content. As your quoted paper (http://journals.ametsoc.org/doi/abs/10.1175/JCLI-D-11-00148.1) correctly says, the surface temperatures aren’t changing proportionally to the heat content.
The article starts with a very prominent OHC graph. Sorry for misinterpreting your article.
Again, when those “large parts” of the ocean (surfaces) are cooling and the heat content is increasing despite this … what does that tell you about the even larger rest of the ocean?
“Do you think the mechanism for cooling of the sea surface is different from the warming mechanism?”
So you have once again refused to answer. That makes 4 times in which I have asked you the same question and 4 times in which you have dodged the question. What that tells me is that you don’t want to admit that both the cooling and the warming are predominantly due to natural processes, and unrelated to anthropogenic CO2 emissions.
To answer your question (yet again, which would include the answer found in the article itself), both the warming and the cooling are significantly related to the natural vertical and horizontal circulation/redistribution of heat on decadal time scales. This is why the North Atlantic is expected to continue cooling for a few more years. There has been no net warming in the North Atlantic for the last several hundred years, and the North Atlantic is multiple degrees cooler now than it was a few thousand years ago – despite the 1/100ths of a percentage point increase in atmospheric CO2. There has been no net warming in the Arctic since the 1930s and 1940s; instead, the recent warming has been part of the natural 60-year oscillation. The Arctic warming has plateaued and will begin to cool in the coming years. Your side is going to have quite a hard time accepting that, so there will likely be some more shenanigans pulled to hide the decline or cover it up.
I’ll ask again: What is the mechanism that has caused the SSTs in the Southern Ocean (14% of the Earth’s surface) to traverse upon a 37-year-long cooling trend, which has led to an increase in sea ice extent since 1979? Please stop with the games play. We know why you refuse to answer. It just makes you appear all the more disingenuous that you cannot admit warming and cooling are significantly related to natural processes and not human CO2 emissions. Will you dodge this question again? Yes, you will.
1) about the cooling of large parts of the Southern Ocean … can we really trust someone who leaves out the important parts when quoting from papers and makes up trend lines in graphs? The quote from the paper with the “occupying 14% of the world’s surface” (Turney et al., 2017) you like to throw in my direction is a very interesting out of context quote. The only time the author writes about cooling trends is when discussing the area around the Macquarie Island. I wonder why you don’t mention that and instead let the quote appear to say that the cooling trend was a trend of the entire “14% ocean”? And finally you take one of the graphs from that paper (https://notrickszone.com/wp-content/uploads/2017/06/Holocene-Cooling-Southern-Ocean-Turney-2017.jpg) and enhance it with a trend line only a skeptic could see/draw.
2) You still don’t get it. Of course, natural processes cause warming and cooling of ocean surfaces. Why wouldn’t they?
But our emissions are causing a forcing that increases the heat content. Other forcings exist too. And you want to downplay this by showing that SSTs change because of currents and internal variability? That’s as if you were claiming that the diurnal cycle causes large temperature changes and therefore the global warming trend doesn’t do anything …
And surprise, nearly every paper from that list I looked at is mentioning the greenhouse effect and what it does to temperatures (and heat content) globally. But for you it is just some weird confirmation of your opinion that it can’t be that humans are causing a temperature increase of water …
Or was it just the area around an island? And is that trend line you put in that graph probably made up?
As are the day and night temperature significantly related to the fact that this planet rotates. Half a year ago I made a pattern test graph for you to illustrate what I mean and apparently that is still needed. So here it is: https://imgur.com/a/IkdQh
Human caused forcing isn’t changing the patterns and you can easily overlook the existence of said forcing, but it is there. In case of the Southern Ocean the signal is hard to detect.
I’ll end with a quote from one of those papers above:
Uh, no. The graphs of both the “Southern Ocean-Wide Sea Surface Temperature” and the “South West Pacific Ocean” (“occupying 14% of the Earth’s surface”) both show cooling trends since the late 1970s–just as the paper says.
https://notrickszone.com/wp-content/uploads/2017/09/Holocene-Cooling-Southern-Ocean-SW-Pacific-Turney-2017.jpg
I’ll replace the current graph with the drawn-in trend line with this one featuring both ocean regions, as the SW Pacific Ocean graph shows that SSTs are cooler now than they were in the 1860s. That doesn’t help your case any, does it?
Why are you continuing to deny that the “Southern Ocean-Wide Sea Surface Temperature” has been on a cooling trend, SebastianH? After all, it’s not as if this hasn’t been reported elsewhere. For example:
Fan et al., 2014
http://echorock.cgd.ucar.edu/staff/cdeser/docs/fan.antarctic_seaice_trends.grl14.pdf
“Cooling is evident over most of the Southern Ocean in all seasons and the annual mean, with magnitudes approximately 0.2–0.4°C per decade or 0.7–1.3°C over the 33 year period [1979-2011].”
Jones et al., 2016
https://notrickszone.com/wp-content/uploads/2016/10/Holocene-Cooling-Antarctica-e-Southern-Ocean-SST-Jones16.jpg
What natural factors/mechanims caused the warmings, SebastianH? What natural factors caused the coolings? You continue to dodge the mechanism question. I’m asking you for specifics, and you won’t answer. Why? What mechanism has caused the Southern Ocean to cool since 1979? What mechanism has caused the North Atlantic to cool since 2005? Answer these questions instead of dodging them every time.
What is the mechanism that has caused the SSTs in the Southern Ocean (14% of the Earth’s surface) to traverse upon a 37-year-long cooling trend
Does it look like it was just the area around an island when the graphs show cooling for the “Southern Ocean-wide SST“? At what point did “Southern Ocean Wide” get transformed into “just an island”? Can you truly be this dishonest, SebastianH?
Where is the hockey team when you need them?
Because we were told that all the missing heat resided in the deep oceans, there must be below the layers where scientists did their measurements, a layer of boiling hot water. When that escapes, we will get the promised hockey stick.
Could be possible … http://oceans.mit.edu/news/featured-stories/southern-ocean-cooling-in-a-warming-world
SebastianH 12. September
“Could be possible …”
The “warming world” is virtual reality created by NOAA homogenization.
VIRTUAL REALITY
If they only used the temperatures in the areas where we have an ability to record them, and ignoring the rest, they would gain real, or at least consistent, information about those areas. It wouldn’t be global, but at least we’d have a handle on what was happening in those areas. Then, if they want to extrapolate, and make clear that’s what it is, to the rest of the world, fine.
By making up temperatures for areas where we have no data, a far more vast area than for which we do have, any average of all is so weighted by the fantasy that reality becomes completely obscured. And then to complete the farce, they “adjust” what little reliable data we have to reflect they’re doomsday cult beliefs.
They aren’t scientists. They are religious fanatics.

Not only do they not know where anyone else is, they don’t even know where they are, anymore. They are lost in a fog of their own contrivance.
Where do you think the authors of the papers above have gotten their temperature data from?

So, yes. Good call.

But why I see 13 links to papers here…
One was added after the original article publication.
One of the pseudoskeptics I’ve run into on the innertubes used this list as supposed evidence that “quite a few climate scientists” are predicting global cooling. Problem of course is that NONE of these papers predict global cooling.
As far as I could tell on my quick read through them they all support the theory of AGW or at least none of them make any claims otherwise.
No, these are papers that are just reporting on the recent decline in ocean temperatures in large regions of the world. They’re observations, not predictions.
As for predictions of global cooling, those are actually rather common. Here’s a partial list of dozens of papers:
1. A Swelling Volume Of Scientific Papers Now Forecasting Global Cooling In The Coming Decades
2. Russian Scientists Dismiss CO2 Forcing, Predict Decades Of Cooling, Connect Cosmic Ray Flux To Climate
3. Scientists Find Climate’s ‘Cause Of Causes’…Highest Solar Activity In 4000 Years Just Ended…Cooling Begins In 2025
4. New Study By German Physicists Concludes We Can Expect Climate Cooling For Next 50 Years!
