Oceanic Warming? Well, sorta.

Guest Post by Willis Eschenbach

After my last post about the surface warming of the ocean, entitled “How Global Warming Isn’t“, I got to thinking about the warming of the upper part of the ocean. So I got the data for the ocean heat content (OHC) of the top 700 metres of the ocean from the marvelous site, KNMI. If you look under “Monthly Observations” you’ll find a host of most fascinating datasets. Under “Heat Content” on that page, you’ll find the National Oceanic Data Center (NODC) 0-700 metre depth OHC data. And down at the very bottom of that page is a link that will download a 196 megabyte gridded NetCDF file containing the data that I used. (Big file, click at your own risk.)

And what did I find? Well, I’m a visual kind of guy. I mean, I can do the math, but it only makes sense when it comes up as a picture on the silver screen. So here are my graphics. I’m interested in the changes in the oceanic heat content, so these are two views of those trends.

Figures 1 & 2. Decadal trends in oceanic heat content, in exajoules (1018 joules) per decade.

I love climate science because I’m continually surprised by what I find. What could be better? It’s like Christmas every day.

My first surprise? There’s a line of giant oceanic slow whirlpool-type eddies that I’ve seen before. They start at the southern tip of Africa and extend down under Australia. I knew about them because they’re visible in graphics of satellite sea-surface height data. But what I hadn’t realized is that these eddies are mixing warm surface water down into the depths. This is indicated by the orange/yellow line of increased undersea heat stretching from Africa under Australia.

And when you mix some warm surface water downwards, other cool deep water has to come upwards … as indicated by the corresponding line of areas just south of the eddies encircled by black/white lines, showing areas that have actually lost heat since 1955. Who knew? Certainly not me.

What else surprised me? The turbulence of the Gulf Stream as it interacts with the ocean floor topography along the East Coast of the US is also mixing warm surface water downwards … and the corresponding upwelling of cold subsurface water is occurring just south of Greenland.

I’ve long wondered how less-dense warmer water could mix downwards into denser cooler deeper waters … well, there are a couple of places where it is happening.

To close out, I took a look at the actual temperature change represented by those exajoules of energy changes. I mean, just how big is an exajoule when it’s at home? I’m sure I don’t know.

But like I said, I can do the math. So I converted the slow increase in exajoules of heat content into degrees Celsius of slow warming. Here’s that result:

Figure 3. Global ocean temperature change, surface to 700 metres depth from 1955 to 2020

A quarter of a degree in a half century?

Now I keep reading about how fish are changing their locations in response to oceanic warming. But it seems extremely doubtful to me because the changes have been so small. Over the last fifty years, the ocean has warmed by about 0.005°C per year … and call me crazy, but I’m just not believing that the fishies and other underwater denizens are so temperature-sensitive that a change of a quarter of a degree in half a century will make them leave their happy homes.

For one thing, in the open ocean, the vertical temperature change is often on the order of 1°C per 40 metres vertical or so. Here are some Argo float profiles of the top 200 metres.

Figure 4. Vertical temperature profiles of the North Pacific, Argo float data.

And that means that if a fishie or other subaquatic denizen goes up or down by ten metres or so, it’s already endured the dreaded quarter-degree temperature change …

Add to that the fact that many millions of oceanic fish, shrimp, and copepods migrate every night from 800-1000 metres depth up to around 100 metres depth, and then go back down at dawn … which means they happily endure 5° – 10° of temperature change every night. So I doubt greatly that they will be bothered by a quarter of a degree temperature change in a half-century.

And by tonnage, this daily vertical migration is the largest movement of living creatures on the planet … so we’re not talking about a few fish here and there.

This is the bottom line. If the world’s creatures, both on land and at sea, were as temperature-sensitive as the alarmists would have us believe, those beings (and we humanoids as well) all would have gone extinct long ago. And near as I can tell, that hasn’t occurred … at least yet.

My very best wishes to all living creatures, terrestrial and aquatic alike,

w.

As Always: I ask that when you comment you quote the exact words you are discussing, so we can all know both what and who you are responding to.

A Final Note: In addition to daily traversing the five degrees or more temperature range, it’s worth noting that when the millions of tonnes of aquatic creatures travel from 1000 metres to 100 metres depth and back down every night, they undergo a pH change of about half a pH unit.

In other words, every night they undergo a greater pH change than we’re expected to see in the ocean in the next century under IPCC assumptions. You know … the dreaded pH change that’s supposed to kill oceanic creatures by the millions. But instead, as Darwin is rumored to have mentioned once or twice, living creatures have evolved to … well … survive.

Willis,
The usual brilliance of topic and data interpretation!
It just occurred to me that not just humans, but most species, are evolved for the tropics! During the Age of the Dinosaurs the tropics were greatly expanded, and the temperate zones were pushed far towards the poles! The non-tropical species are the outliers, so why would we NOT want a slightly warmer world?
Thanks for leading this old horse to water, and getting him to think!

An atmosphere creates a thermal resistance, R, just like all those batts of insulation down at Home Depot. That’s what makes the surface warmer than the top of the atmosphere just as R makes the inside of the house warmer than out. Or cooler in Phoenix.

Picture a large south facing window. The solar energy just pours in, heating the room. Draw the draperies. Is the room cooler now or warmer? By reflecting the solar energy the room is
cooler aka albedo.

Picture a large north facing window. It’s 20 F outside. Heat from the room is just pouring through that window running up the heating bill. Draw the draperies. Is the room cooler now
or warmer? The thermal resistance, R, of those curtains slows the heat loss and lowers the gas bill.

Same draperies, two different results depending on the application.

The atmosphere/albedo cools the lit side and its R warms the dark.

That’s NOT a greenhouse effect and carbon dioxide/GHGs are NOT involved.

I have a large open-area semi-split first floor. The equivalent of eight windows and one large patio door – from East to South to West in the main area.

The weather could be -30C outside in the winter, my heat is set at 15C for 24 hours when it’s sunny. The full house is warmed, even the North-East room elsewhere. The basement is set at 18C.

And my bedroom (West-South) is set at 10C all winter. Never a problem.

The sun-generated heat mixes in everywhere although I do wear socks but not a sweater. Because I walk through the house, I move the heat with me. And at night, it’s the heat from three lamps.

I just don’t understand all the crap about ‘green’ reconstruction of buildings when all you need are windows.

PLUS, at bedtime, you don’t want a hot room because the heat you generate in bed is sufficient to sleep well.

Cooling and warming are the wrong words. Curtains, blanket or what ever are inanimate objects. They can not do an action or activity. They can reduce the heat flow through thermal resistance. In the first case the heat inflow from radiation is reduced. with the latter case the heat outflow is reduced. Note that the second law of thermodynamics always applies. Heat only flows from hot to cooler. The alarmists have fooled people by talking about warming. CO2 does not warm or cool. CO2 absorbs a very tiny portion of the radiation spectrum at around 14.8 micron wavelength. It also radiates at that wavelength (around 220K) to space. Clouds which are composed of droplets of water and particles of ice are much more important affecting heat flowing to and from the Earth’s surface. Not only is there heat flow by radiation affected but also by convection and phase change ( condensation -which gives off heat, evaporation which takes in heat, and fusion to and from ice which similarly gives off and takes in energy)

Spot on. CO2 absorbs and re-radiates (in all directions) energy as does water VAPOR. Neither are insulators or heat flow “resistors” as insulation is. Analogies to greenhouses or blankets lead to bad science and misunderstanding. Look up Feynman’s interview when he was asked to explain the repulsive force between opposite magnetic poles.
https://youtu.be/MO0r930Sn_8
He explains that answering the “why” of observable phenomena requires some basic scientific understanding of fundamentals. For the atmosphere, thermodynamics and radiative physics, for instance. Not greenhouses and blankets.

Feynman’s response was painful. He was vamping, while trying to figure out what the cognitive disconnect was, and in so doing just made it look like he didn’t know what he was talking about. But his final statement was dead nuts: I can’t explain it in terms of anything you’re more familiar with. He could have just said: “It’s like an axiom in logic, or mathematics. It just is, and can’t be proven in terms of anything more fundamental.”

Willis – maybe a bit off-topic, but you talk about a 200MB file as being “massive”.
I know you live in the sticks … not sure how far out, but I get the impression that wherever it is, you are getting somewhat poor Internet service if you consider files of that size as massive.

You may want to take a look at Starlink. They are slowly rolling out production service, and it seem to be running up to 200Mbps. Might make your life easier.

Don’t forget the pressure changes the aquatic creatures also can endure. Every 10 meters of ocean depth increases pressure by one atmosphere. Not only can they endure that, but they never get the bends either because there is no nitrogen in their bloodstream to decompress.

Interesting! I was wondering about that. So what about marine mamals who breath the air? How do they avoid the bends? Some dive deep and fast.

Reply to  Joseph Zorzin

They do not breathe underwater. The trouble starts when you are deep and your air supply needs to be pressurized to balance the ambient pressure. So you start breathing air at high pressure and that is what saturates you to the point you get bubbles going up.
(Rule of Thumb: 0.5 psi for each 1 foot of depth, so 100 ft. gains 50 psi. pressure)

Trivia point:
N2 at high pressure acts like a narcotic, a diver can get seriously deranged mentally. This is another reason they use a helium mix.

As you dive, the air in your lungs gets compressed. Your lungs actually shrink and your diaphragm moves up and in. The air in your lungs is within a few psi of the water pressure. Therefore, the nitrogen in that breath of air is also compressed. Free divers don’t stay down long enough to absorb much nitrogen into their blood. Whales and commercial deep sea divers do. I am not sure how the whales do it and not get the bends when they return from a deep dive looking for food. Deep sea divers live for weeks in pressurized chambers so they don’t have to spend all that time decompressing. Really, it should be called degassing. Helium is used in the mix to avoid nitrogen narcosis and because it is less soluble in our blood than argon or nitrogen.

It’s the Sperm whales that dive the deepest. Over 3,000 ft at times! And there is evidence that they do get the bends.

They are not breathing, thus there is no extra nitrogen to dissolve in the blood. The nitrogen they do have was dissolved at surface pressure so will not misbehave when they return to the surface.

Different from the bends. Rapid pressure changes for fish with swim bladders never happens in nature. But not all fish have swim bladders.

Water is weird:
.
Since water at about 39°F (4°C) is more dense than water at 32°F (0°C), in lakes and other water bodies the denser water sinks below less-dense water. 

Which is why the oceans and lakes freeze from the top down.

The density is irrelevant any body of water will freeze from the surface when cooled from above because the freezing point increases with water pressure. So the surface has the lowest freezing point of any other point in a body of water and when cooled from above will therefore freeze first … density is irrelevant. It’s basic there is no other way it can freeze when cooled from above the physics in that graph tells you that.

water freezes from the top.
==≠===
But unlike most materials, solid water floats on top of liquid water, limiting further freezing.

Water also has many other properties essential to life. Largely ignored in the CO2 madness.

Without a doubt, water is the Earth’s climate regulator, with the phase changes limiting both cooling and warming.

No. If ice was more dense than water, it would sink when it froze and no longer insulate the surface of the water.

Typically solids are more dense than liquids. Water is an exception and it is lucky for us as the oceans would likely be filled with ice at depth otherwise.

When it comes to sea water freezing, the density is totally relevant.
Pressure is not relevant.
The changes in density or freezing point with changes in pressure are trivial at normal pressures anywhere near the surface.
What matters is the relative density of water and ice at varying salinities and temperatures.
Sea water does not exactly freeze from the surface down.
Ice crystals form, then sink due to being more dense.
Then, as they grow and salt is excluded and the water becomes mostly fresh with less and less salt, the crystals rise to the surface.
But it is very complicated.
Frazil ice can and does freeze onto subsurface structures and accumulate, and causes large amounts of damage in certain situations.
And brinicles form and grow along the sea floor.
Anyone saying different is talking off the top of their head without actually checking to be sure they are correct.

Since there is no such thing as pure water in any natural body of water, the impurities have a far larger effect than pressure ever could, but it is insignificant compared to the difference in density caused by the phase change and molecular realignments.
The pressure under a ice skate blade is not relevant to what happens when ice forms on a body of water on Earth.

Or in an ice cube tray.
If it is a cold freezer, ice will form at the top, but also all along the sides and bottom…wherever contact is made with a cold solid object.

The place where that phase diagram juts to the left between solid and liquid is like Marianas trench type pressures.
Always best to check facts before insulting people.
The idea that pressure melts the ice under a skate is a 19th century hypothesis that is not supported by physics.
See the money quote below in the picture.
Unless you weigh about 1400 kilograms or more, it is not the pressure melting the water under an ice skate.
That idea is debunked rather convincingly by several research papers and some unassailable physics.
It is just that few people ever look anything up after they learned it in fifth grade to see if it was really still true in the actual world of science.
And then people publish phase diagrams that bear no relationship with reality.
So it is perhaps understandable if one does not poke a little deeper.

According to the article, “Pressure Melting and Ice Skating”, published by a geophysicist, Samuel Colbeck in 1995 in the American Journal of Physics, the decrease in friction could not be due to high pressure-induced reduction of the freezing point. He explained that at 0 °C, for every additional pascal of pressure exerted, it would only cause a decrease of 7.37 x 10-8 °C in the melting point of water, due to the pressure-melting effect. Therefore, if we are skating on a -1 °C ice surface and we want to lower the melting point to -1 °C, by calculation, a pressure of 1.4 x 107 Pa (around 140 atm) is necessary. Assuming that the contact area between the blades and the ice surface is 10 cm2, to exert the equivalent pressure2, the weight of the skater must reach 1400 kg. We clearly know that it’s impossible, and that’s why the melting caused by pressure change is not a convincing reason to explain why we can skate freely on ice.”

sciencefocus.ust.hk/extraordinary-science-the-mechanism-of-ice-skating

Yeah, and here is them brinicles, showing that it is definitively not true that ice can only form at the top.
No source of info shows the ocean freezing that way.
We just see the ice after the frazil floats to the top after excluding the salt.

I do not know where that phase diagram came from, but at the sorts of pressures at and near the the top of a river or lake on the surface of the Earth, pressure is not a significant factor, ice skating notwithstanding.
That diagram is wildly out of scale. Or something.

Whoa…wait a second.
One hundredths of a degree?
And what is the salinity variations, and other chemical differences, and how much effect do they have?
More then 0.01°C in many if not most places.
You posted the maps of salinity variations yourself.
Any impurity in water, or in anything else, cause freezing point depression and boiling point elevation. Basic physical chemistry.
It does not even matter what the impurity is.

Sea ice freezing is a complex dance of factors, including the salt being excluded from the ice crystals as they grow.

Including the fact that…..wait for it…
Water freezes from the top because that is where the cold air is!
And it stays there because ice is less dense than water.
(For fresh water)
Substantially.
And there is no heat sink 1000 meters down to make the water freeze down there. To get a phase change, one must have a place for a whole lot of energy to go.
Unless the water is supercooled down there…and then it can freeze suddenly all at once.
I suspect it may be in places supercooled, especially if some chemical alteration takes place and some shock forces the reaction.
Imagine a few tens of cubic kilometers of water at the bottom of the ocean suddenly freezing due to having been supercooled and then shocked.
What would happen?
Welp, that ice would explode catastrophically up to the surface, and would perhaps cause a chain reaction with any and all supercooled water down there.
Spreading across the entire world ocean!
And then we would have the entire ocean flipping, bringing freezing cold water up; and mixing the warmer top layers down.
The result would be a true ecological catastrophe, and may be enough to …trigger an ice age? Definitely…and then some!
All the warm water is now mixed with freezing cold bottom water, .
Krikey!

Also important to note that the process of freezing sea water is a complicated thing because as the water begins to freeze, it excludes more and more of the salt, which has to go someplace else…like down.
So there are tentacles of hypersaline and ultra-cooled water extending downwards from sea water in the process of freezing.
And sometimes heavy precip adds a layer of fresh water on top which starts out as snow, and this can sometimes jump start the whole process.
Brinicles are amazing, and we have posted and discussed them here often.
And the stages of freezing seawater undergoes is a whole subject of study in itself.
comment image

BTW…pressure has no effect on the freezing point at normal pressures.
Water is incompressible.
See the phase diagram for water, attached below.
The line between solid and liquid is vertical with respect to pressure.

It freezes from the top down in freshwater bodies and ice cube trays because ice is less dense than water.
Water becomes more dense as it cools, like almost everything, until it reaches about 4°C, at which point it begins to become less dense due to the molecules beginning to line themselves up into the positions they assume in ice.
The polar nature of the molecule forces them apart as the charges line up.
Still trying to find the same phase diagram for salt water.
Anyone? Anyone?

Well, The Guardian often reports “marine heat wave” events.
(which of course are always “worse than we thought”)

So it’s not inconceivable that an apocalyptic instantaneous temp or pressure change gradient could create giant undersea waves.

I have been struck by one while oil field diving in NW Australian waters. At a depth of 420 feet in clear water with no current a dark shadow at the extent of visibility appeared. When it arrived I estimate the current at six knots and no visibility. On getting into the dive bell it was hanging out at a fifteen degree angle. Somewhat unsettling. Certainly enough to upset a subs trim.

Saw a thingey once, showing a constant string of giant vortices forming around Cape (Town) Point and swirling off in conga-line towards South America. The graphich showed what can only be described as gigantic underwater tornadoes, submarine weather par excellence. I remember the location/s different from your graphic, but then I remember, We are talking about two totally different phenomena, yours being static over time. What a simple way to present so much data! Kudos.
I am obviously biased towards seeing a warm line along my (possibly fictional) ‘marine tornado path’. The question is; how many other such “geospoons” are there really? Disregarding all the many other processes stirring the seas, one must not forget that the ocean at the equator is moving at a thousand miles an hour, dragged by the moon against continents moving at a thousand miles an hour. Even granma can tell you things crashing at high speed always is worse, even if both cars were going in the same drection. Continent, meet tidal drag… that’s one hell of a stirring action right there.

“Over the last fifty years, the ocean has warmed by about 0.005°C per year … and call me crazy, but…”

Well, 5 C in a thousands years is CAGW type stuff.
As is .5 C in hundred years.
I sort think the entire ocean “can’t” warm by .5 within a century. And I still don’t think it happen.
But it seems ocean going from average of about 3.5 C to 4 C or to 3 C is huge change to occur within couple centuries of time.
Or my guess is the Holocene Maximum was as much a 4 C ocean. And warmest Eemian got was about 4 C [or maybe more].

Willis: “Add to that the fact that many millions of oceanic fish, shrimp, and copepods migrate every night from 800-1000 metres depth up to around 100 metres depth, and then go back down at dawn … which means they happily endure 5° – 10° of temperature change every night.”

WR: we can add the yearly summer/winter temperature differences: most of the oceans show large differences in summer-winter temperature: from 2 degrees even up to 24 degrees. Without any disturbance.

Win, interesting! The very minor change in the southern polar regions, (0 to 4 C) compared to the very large, up to 24C!! swings in the northern poleward regions.

On the face of it, swings that large as shown, are not easily understood. The base winter T may be what, 29 F at the extreme?

Regardless there is no doubt a lots of energy leaving the oceans on some of these extremes. And it would be fascinating to compare this to the CERES data, thanks to Willis.

Which reminds me, what are the error bars in this upper ocean .25 C warming? And a further question for anyone, is it even possible for the SST variance, and the 2 m atmosphere surface T to decouple?

If the answer for the most part is “no”, then any lower troposphere surface warming is limited, or tightly constrained to ocean warming.

David A: “The base winter T may be what, 29 F at the extreme?”

WR: At first sight the very small amplitude between summer and winter temperatures of the polar oceans surprises. It is the system of sea ice that keeps temperatures year-round near zero Celsius (-1.8°C or 29F). Seawater freezes at minus 1.8 degrees Celsius. Below sea ice -1.8°C will be about the temperature of the seawater. When the summer arrives, the melt of sea ice uses a lot of the energy brought by the Sun: surface water temperatures don’t change much. At mid-summer in the Arctic and Antarctic there is still a lot of sea ice left:
https://ads.nipr.ac.jp/vishop/#/extent
(click on Arctic and Antarctic)

When nearly all sea ice is gone (in the Antarctic around half of February), the Sun is also near leaving the south pole.

The moment sea ice is covering the oceans, the mixing of water below the ice is constrained. Below the ice water will stratify, further constraining ocean heat loss. And often sea ice is covered with insulating snow. Over polar areas a lot of low clouds are found, constraining radiative heat loss. These examples of what I call ‘horizontalization’ in the ocean-atmosphere system, diminish both heat loss and heat gain and as such prevent high fluctuation of ocean temperatures around the poles.

Willis explained well that the ‘verticalization of warm humid air’ in the tropics (thunderstorms) limits the ocean temperature at the upside to 30 degrees Celsius. The system of horizontalization (insulating) and verticalization (the ’emergency exit’) are part of the solid system that controls surface temperatures, especially at the extremes.

At the mid-latitudes we find the largest temperature swings. Here the role of the Sun is larger and the role of sea ice is nearly or completely absent. Cold currents and winter atmospheric systems can locally and temporarily influence surface temperatures strongly: see for example the oceans around Newfoundland and North Japan.

Very interesting, not always so somewhat similar things go on in shallow, and even deep water bays and oceans. Poor tiny critters have a hard time staying vertical. Larvae and their immediate metamorphosis have a lottery scale survival chance which is why they are produced by the trillions. Next time you cross a body of windy water watch the Langmuir circulation, evident lines with bubbles, flotsam and jetsam are convergence (downwelling), in between divergence (upwelling). Not as regular as the models, some lines have “freeway” exits. Langmuir discovered the circulation with light bulbs and umbrellas. Hasn’t been studied much since, makes you 3-D seasick I suppose. It can be surface measured with infra-red. Langmuir, I. 1938. Surface motion of water induced by wind. Science. 87:119-123.

Sailfish in Cape Cod Canal?

The Gulf Stream produces circulating eddies of warm water several tens of miles across and even a few hundred miles across. These eddies can entrain local marine critters when they form in the tropics and subtropics. Because the water is warm and the environment familiar, the creatures have no reason to head south or west. The creatures caught up in these eddies are then transported north to New England and even as far as Atlantic Canada. The eddies eventually decay and the fish make surprise visits to the New England shore on their way south.

All this has been well known and properly understood since forever. The Yale360 article is sheer alarmist drivel, OR demonstrates the totally clueless nature of the Yale researchers. If I was a student there, I would want my money back.

Arctic sea life is coming back strong, RECOVERING from the extreme sea ice and cold of the LIA and late 1970s.

Not only is the land surface GREENING, but the seas are also springing BACK to life after being TOO COLD and frozen over for much of the last 500 or so years (coldest period of the Holocene)
The drop in sea ice slightly toward the pre-LIA levels has opened up the food supply for the nearly extinct Bowhead Whale, and they are returning to the waters around Svalbard.

https://partner.sciencenorway.no/arctic-ocean-forskningno-fram-centre/the-ice-retreats–whale-food-returns/1401824

https://journals.sagepub.com/doi/abs/10.1177/0959683617715701?journalCode=hola

Many other species of whale are also returning now that the sea ice extent has dropped from the extreme highs of the LIA. Whales cannot swim on ice. !

Obviously you have never been in and around the Gulf Stream. If you go offshore from Cape Hatteras in the winter you can go from 50F water to 75F water in 20 feet and the water will go from green to tropical blue. The fish will change from cold water species to tropical species.

As it goes north of the Cape it meets the Labrador Current and starts swirling into eddies. Tropical fish get trapped in these and if the eddies drift northwestward, you can catch Mahi Mahi or sailfish off Boston. It is not unusual and happens occasionally.

Not just in the oceans, either! I have puzzled about claims of land-based biota being endangered by changes upward by fractions of a degree. Other than short-lived insects most biota experience and presumably acclimatise to diurnal variations of up to 10ºC or more.

Gary, I explored your question in depth in essay No Bodies in ebook Blowing Smoke, analyzing AR4 WG2 claims. Turns out the IPCC charts are very deceptive. The ONLY generalized IPCC species conclusion comes from just one paper. That paper had no less than four major problems: faulty z, grossly overhot GCM, biased species study choices (example Queensland birds—Queensland has ~630 bird species, of which ~20 are endogenous [all birds of paradise] of which they modeled 13), faulty weighting of their six ecosystems.

Essay exposed all the fatal ‘climate science’ flaws and misrepresentations

The vast majority of species, both oceanic and terrestrial, live or evolved in the tropics! Why hysterical alarmists are concerned about a small warming cycle and the subsequent expansion of the tropics is almost enough to beggar one’s belief!
Many of the species living in and around higher latitudes are more recently evolved; like orcas and polar bears. If only we could convince the orcas to deal with alarmists like they dealt with Megalodon!

Attenborough presented a well known dichotomy. Not new news. The harsher the environment, the fewer the species. Reason is simple, fewer ecological niches into which to differentiate. This has been taught in basic ecology since I took it about 1970.

I like this little chart from Bob, showing just how little of the oceans was actually “measured” until quite recently.

Always makes me wonder about where the actual temperature data from, say 1960 came from and how realistic they are.

Willis’ line of eddies starting off the Cape of Good Hope show up nicely on “earth”

https://earth.nullschool.net/#current/ocean/surface/currents/orthographic=75.48,-94.13,556/loc=75.482,-89.958

It looks like warm water from the Indian Ocean is being sucked into the circumpolar clockwise current of the Southern Ocean. After some turbulence off the coast of Argentina and the Falklands, it seems to come around for a second turn of a spiral. Like bathwater circling the drain.

The colours on this presentation indicate speed of the currents. If you change the overlay to temperature, the trend is not so obvious.

One thing I give to the late not-so-great oceanographer Wally Broecker (inventor of the gross-oversimplification called “The Great Ocean Conveyor”) was that he did at least acknowledge that the Antarctic circumpolar current “serves as the great mix-master of the world ocean. It blends the NADW exiting the Atlantic with new deep water generated along the perimeter of the Antarctic continent and also with old deep waters recirculated back into the Antarctic from the deep Pacific and Indian Oceans. So efficient is this blending that the NADW entering from the Atlantic loses its identity before it passes even one half of a revolution around the Antarctic!”. (OCEANOGRAPHY-Vol. 4. No. 2-1991 79. NADW = North Atlantic Deep Water)

Great stuff as usual Willis, thanks.

Is there a reason why polar data, “polar amplification” is dispersed to the public in temperature anomalies? Ha ha yeah, no prizes for guessing the answer, and no prizes either for guessing why Antarctica is only mentioned by people who haven’t looked at the data for 15 years. At this point, actual scientific fraud, not borderline scientific fraud would be the answer.

It would take me a lot of time that I don’t have to get up to speed on that calculation but you may have it literally at your fingertips. I’m talking about the “Joule” anomaly at the poles versus the “Joule” anomaly in the tropics. You wouldn’t surprise me if Arctic amplification barely exists when measured in Joules.

This post is more of a question then a comment:

Is the temperature of the permanent ice (some places 4 – 5 meters thick) that floats at the North Pole incorporated in the average temp of the Arctic Ocean?
This permanent ice must be way colder than the 28.8 F, needed for freezing salt water.

If you Google the question, you get this:
What is the temperature of the Arctic Ocean?
28.8 °F

That answer seems to only account for the liquid part, and probably discounts the frozen – very cold ice – part as not relevant for calculating the average temp of the Arctic Ocean.

Any thoughts on this?

Thanks for replying Willis. As you state: There’s no “right” way to measure it.
But isn’t that the broader problem: How an we really know/measure the average temp of anything globally, be it oceans or land? who can say with certainty what the temps were in 1880, and then claim we cannot allow it to increase by more than 2 C, by 2100,even if we could control it, which we cannot? The idea is beyond mad, but there are plenty people believing this. WUWT is my safe space, thanks!

Reply to  sailor76
May 1, 2021 7:14 pm

That 28.8 degrees is the temperature at which the salt water starts to freeze. As it freezes the ice gets thicker and the water below it can no longer directly radiate to space. The air above the ice gets colder because the conductivity of heat through the ice decreases with increasing thickness. The ice increases in winter and decreases in summer. Also noted, CO2 builds up over the ice in winter and is completel absorbed by the open water in summer. There is no year-to-year accumulation. The year-to-year rise in concentration is the result of increased natural emissions from tropical oceans, not anthropogenic emissions. Natural emissions are 20 to 50 times more than anthropogenic emissions.

sailor76
Reply to  Fred Haynie
May 2, 2021 6:24 am

I do agree that natural emissions probably by far outstrips anthropogenic. But how do you explain that during the MEWP the CO2 level remained flat at 280 ppm, according to the Greenland ice core measurements? There should have been a rise during that time as well, no? Any explanation?

Richard Page
Reply to  sailor76
May 2, 2021 10:02 am

I’d be very interested to find out if ALL of the ice cores agreed on exactly 280 ppm or if there was some degree of difference between them? Also what thickness of ice/sample size represents the length of the entire MWP record?

sailor76
Reply to  Richard Page
May 2, 2021 10:59 am

In the graphs at the link below, there is a slight rise of CO2 around 1200 AD and slight dip from 280 around 1700-1800 AD (LIA)

https://www.co2.earth/co2-ice-core-data

I guess one could interpret that to mean that temperature variation and CO2 levels are minimally related.

Richard Page
Reply to  sailor76
May 2, 2021 2:05 pm

So 275-284 ppm, allowing for an error range of, what 10% for sampling/reading error, is something like 250-300 (ish) ppm. Given that there were only a few samples taken within the MWP range, I’d guess that the ice was compressed immensely – down to something the thickness of a burger (or less most probably). So how much CO2 was squeezed out as the ice was compressed?
As to a relationship between CO2 and temperature – not absolutely linked I should imagine. Consider that as temperature rises, plants do better and natural CO2 increases. However, we haven’t seen a great increase in natural CO2 after the Minoan and Roman WP so maybe the duration of the warm periods has been too short to jumpstart greening and increase natural CO2? Given that natural CO2 has been bumping along just at starvation levels for most of this interglacial, perhaps the introduction of fossil fuel CO2 has been exactly what was needed – were we just 1 or 2 ice ages away from losing all life on this planet?
See I can do apocalyptic doom and gloom as well as a bunny-hugging climate enthusiast.

Willis, thank you another interesting post. You wrote:
“But like I said, I can do the math. So I converted the slow increase in exajoules of heat content into degrees Celsius of slow warming. “

My question is: didn’t they calculated the increased ocean heat from temperature data in the first place? I can’t think of another method of measuring these data.

Another question: do you agree that any warming must be either due to solar radiation or ocean mixing, since water doesn’t heat up by LW radiation? I assume that convective heat transfer by the atmoshere can’t explain these amounts of exajoules because the increased temperature difference would be far from be sufficient (or not?).

The turtle people at Stanford Woods Institute for the Environment

claim, via a press release, that “As the planet undergoes unprecedented climate changes, locations once considered impassable obstacles to species movements, like the Eastern Pacific Barrier, are being redefined. This, in turn, is shifting the distributions and migratory pathways of creatures ranging from sea birds to white sharks and presenting new conservation challenges.” One of the authors gave a nice interview on today’s CBC Quirks & Quarks, and the host is always glad to bring climate change into the equation. I was about to send her the link to Willis’ article, but decided not to. My experience with biologists who invoke future climate change is not positive. It seems most of them do not even think of the record of even relatively recent climate change.

I’m no scientist but just follow fish-trawling vessels. If they operate in the same international waters and other spots, year after year, it’s because there are lots of fish in those areas that haven’t migrated.

Just as with your home, if there are too many people living in it, some leave and migrate elsewhere and even adapt to other areas. I figure it’s the same with all living creatures on this planet.

“I’ve long wondered how less-dense warmer water could mix downwards into denser cooler deeper waters”
Are you sure it is less dense? Salinity counts as well as temperature.
Water gets less saline away from the tropics, and if the Gulf stream wanders into less saline waters, warm water can sink.

So, a constant supply of cold, fresh water from the poles getting mixed in with old, evaporation-experienced water, less well as we go equatorwise, with near total good deal of stagnation between the two longest landmasses.
And then there are the little hotspots along most every coast. Harbour sensors? Something clogging the ones on/near the beach?
If this kind of measurement is to go by, no wonder they have to adjust so many of their other measurements, which hubris would eventually turn into measurements to fit the narrative.

Nick, I am pretty sure that the common range of salt concentration (outside a few places like the Mediterranean and the Red Sea) is not enough to overcome more than the density difference due to a change of a few degrees temperature. The deep convection areas in the north Atlantic (where the Gulf Stream goes to die) are very cold and dense, and the convection is very deep.

Your nicely colored map mostly shows where it rains a lot and were it doesn’t. Look at the West Pacific warm pool area… it has low salinity and high temperature, because there is a lot of rain. Those bright orange/red areas are NOT where salty surface water is sinking to great depth; the salty water is floating on top of much colder (and denser) deep water. Where the salt concentration is high is where there is a lot more evaporation than rain.

Willis,
Relatedly, I am studying a publication by 15 authors from the Australian Academy of Science, a veritable Cinemascope wide screen polychromatic production with 450 references.
https://www.science.org.au/supporting-science/science-policy-and-analysis/reports-and-publications/risks-australia-three-degrees-c-warmer-world
A repeated theme is that a warming globe will generate heat waves that are hotter, longer and more frequent than before. This includes marine heat waves. Here is the abstract of one reference by Oliver at el that they list to support this presumption:
Marine heatwaves are important events in oceanic systems that can have devastating consequences for ecosystems, causing ecological changes and socioeconomic losses. Prominent marine heatwaves have occurred recently and attracted scientific and public interest, but comprehensive assessments of how these events have been changing globally is missing. Using daily satellite observations, daily in situ measurements, and gridded monthly in situ-based sea surface temperatures we identify significant increases in marine heatwaves over the past century. We further estimate future changes in marine heatwaves to the end of the 21st century, as simulated by CMIP5 global climate model projections. We find that from 1925 to 2016, global averages of marine heatwave frequency and duration have increased by 34% and 17%, respectively, resulting in a 54% increase in annual marine heatwave days. Importantly, these trends can largely be explained by the increase in mean ocean temperatures, rather than a change in variability. Future projections show significant, and accelerating, increases in MHWs properties into the 21st century with many parts of the ocean reaching a near-permanent MHW state by the late 21st century, regardless of emissions scenario considered (RCP4.5, 8.5). Comparison with simulations of a natural world, without anthropogenic forcing, indicate that these trends have emerged from the range of natural variability within the first two decades of the 21st century. This implies that the climate system has departed significantly from natural marine heatwave conditions under which ecosystems evolved, and therefore impacts on marine ecosystems can be expected to be widespread, significant and persistent.

Clyde, if I understand my radiative climastrology correctly, it works like this: When those fishies rise from the ice cold depths, they cool the top layer of water, which means it cannot radiate heat, so it traps all the heat down on the bottom of the sea, causing the little tube worms to complain about itchy sweaters.

Willis, my understanding of mankind-created global warming is that the increase in heat in the oceans will have come from the atmosphere. The atmosphere has a mass of about 5E+18 kg. Assuming a specific heat capacity of about 1 and an increase in temperature of about 0.5degC since 1950 (up until 2013, IPCC AR5), the atmosphere has increased its total heat by about 2.5E+18kJ or 2.5E+21J. So there is enough extra heat in the atmosphere to cause the ocean warming you describe, if that is the cause and mechanism. Is this your understanding?

That approach provides an average for all the oceans, and is appropriate for generic geothermal heating arising from primordial heat in the core. Your figures 1 & 2 show hot and cold spots. To be comparable, you should probably divide by an estimate of the areas of spreading centers (and active seamounts), where the mega-plumes occur, and tag it “potential local heating from transient volcanic events.”

Interesting. I think you found more evidence for your “Emergent” temperature regulation hypothesis.

If you derive the heat capacity of the oceans to 700 m depth vs the heat capacity of the entire atmosphere, the difference is roughly 293 times.

That is the oceans to 700 m depth have 293 times more heat capacity as the entire atmosphere.

So if an increase of (x) exojoules have been observed in the top 700 m of the oceans, and that is a 0.25 deg C rise in that water temperature, then either:

a) the air temperature should have risen by 293 x 0.25C or 73.4 C; OR

b) the emergent temperature regulation systems of the atmosphere simply ramp up the dissipation of that extra energy as per your hypothesis.

Or is my view too simplistic?

How does CO2 warm water that 13 to 18 micron LWIR can’t reach? The only mechanism CO2 has to affect climate change is through the absorption and radiation of 13 to 18 micron LWIR, and those wavelengths don’t penetrate the oceans, yet it is the ocean 50 m depth that is warming. That is due to visible radiation, not IR.

And that means that if a fishie or other subaquatic denizen goes up or down by ten metres or so, it’s already endured the dreaded quarter-degree temperature change”

Interestingly, this is consistent with the observed depth changes from one indicator of marine species movement:

Unfortunate reification of data — it is unlikely that any particular spot in the seas, say a given cubic km of the Pacific Ocean, has really experienced a permanent, discernible increase in water temperature of any degree whatever.

That’s not to say that somewhere some spot of some ocean may have not warmed somewhat over some period of time – we see periodic warmings and cooling in the El Nino/La Nina cycle, and every year in the annual summer/winter cycle.

But one cannot make a truly scientific leap from a global map of “anomalies” to any real world experienced actuality. Mörner showed this over and over again with sea level and I suspect the same is just as true about ocean heat/temperatures.
