MIAMI—A new study led by scientists at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, in collaboration with scientists at Princeton University, shows that the intensification of global hydrological cycle drives more ocean heat uptake into the deep ocean and moderates the pace of global warming.

As a result of a warming climate, the global water cycle becomes more intensified and as a result wet regions are getting wetter and dry regions are getting drier. The researchers found that this intensification is also reflected in ocean salinity. The increase in ocean surface salinity in salty regions, such as the subtropical oceans, leads to denser seawater and more heat uptake in to the deep ocean. The increase in the rate of ocean heat uptake would reduce the rate of surface warming. 

“We discovered a new mechanism that influences the rate of global warming through a suite of climate model experiments,” said Maofeng Liu, a postdoctoral researcher at the UM Rosenstiel School, Department of Atmospheric Sciences. “The good match between climate model simulations and observations in the past few decades suggest that the salinity changes due to human-induced warming are likely working to enhance the ocean heat uptake.”

To conduct the study, the researchers used a global climate model to conduct two sets of experiments. In the first set of experiments conducted as a baseline, they increased the atmospheric carbon dioxide concentration one percent per year until it doubled. In the second set of experiments, they repeated the first experiment but do not allow the surface salinity to respond to the CO2-induced global hydrological cycle changes. The different outcome from the two sets of experiments highlights the impact of the water cycle changes in the ocean heat uptake and transient climate change.  

Global warming from emission of greenhouse gas into the atmosphere is increasing sea levels and resulting in more frequent and intense storms, drought, and wildfires.

“Predicting the rate of global warming is still a challenge,” said Liu. “This study found a new impact to the rate of global warming.”

The study, titled “Enhanced hydrological cycle increases ocean heat uptake and moderates transient climate change,” was published on Sep 23, 2021 in the journal Nature Climate Change. The study’s authors include: Maofeng Liu, Brian Soden and Bosong Zhang from the UM Rosenstiel School; and Gabriel Vecchi and Wenchang Yang from Princeton University.

Funding for the study was provided by National Aeronautics and Space Administration (NASA) and the U.S. Department of Energy (DOE)

“through a suite of climate model experiments,”

As soon as I read the title I knew it would be a discovery in the fantasy world of a non validated computer model.

There are so many ways in which their models do NOT match what the climate does in reality, there is ZERO validity in all these “experiments” as what a model does.

Unf. the current models don’t predict the precise opposite of reality. Those would be useful models, similar to this one: “Everything Joe Biden says is true.” The utility lies (no pun) in taking the opposite as true, and assuming that everything Joe Biden says is a lie. That rule has actual utility, and I use it every day, unless Joe says he intends to do something stupid. That you can believe.

Alas, the present climate models are more like the famous compass made briefly by Tates Instrument Comany. Due to a persistent manufacturing error, the Tates compasses pointed in a direction that was not 180° off, but approximately 75° off from magnetic north, resulting in the truism, “He who has a Tates is lost.”

But the more important thing imo is -where the hell is the sea level rise?
Now I’m missing it more than ever.
Besides all the(official )massive record melts of the last 3 decades we have now discovered far more heat uptake into deep oceans
we now have to deal with the thermic expansion of oceans that are on average about 1.5 km deep.

If anyone is interested I found a gem of a little book:

Stalin and the Scientists by Simon Ings.

Its in the category of “popular science”, so it is not too in depth, but it does help if you have some knowledge of the the USSR and it’s history.

I liked the book because it really tells the tale of trying to do science in an ideological political atmosphere that is essentially “averse to truth“. The parallels between what we are living through now, with CAGW and what was going on in the Soviet Union then are amazing.

If you have ever heard the term “Lysenkoism” this book goes into in detail. It was essentially responsible for killing millions of Soviet peasants. The idea of seed vernalization, once latched on to, was impossible to halt. And anyone who got in the way was eliminated, including the entire field of genetics. The Soviet press was not micro-managed but so captivated by group-think and “the narrative” that it printed nothing but instances of spectacular successes. So, when Lysenko was challenged by the geneticists he pointed to the thousands of newspaper articles that touted his methods; basically accusing the geneticist of calling millions of citizens liars.

Lysenko had no academic credentials, virtually no scientific publications but had all of Soviet agriculture behind him, due to the media/press.

The book describes an upside down world where ideology subsumes reality. And this often pitted Soviet scientists, who were shackled by reality, against the society.

Thus you would get stuff like “warming induces cooling“. When the harvests never materialized, seed vernalization was never questioned, it was always something like: the seeds were not soaked long enough, the seeds were over soaked, the temperature was too hot or too cold, the seeds were cooled for too long a time or too short a time, etc.

Excerpt: Imagine basing your entire agricultural economy on a single plant:

The Lutescens plants lived until the late autumn and died without heading. In the middle of August 1935, one of the Kooperatorka plants died when pests ate its roots. The other one, however, did manage to head. Several paired seeds were collected from the surviving plant on 9 September 1935 and sown beside ordinary Kooperatorka plants in a hothouse. Unlike their neighbours, these unvernalised seeds grew happily in warm conditions, proving that they had been transformed into spring varieties.

Ludicrous as it was to base anything on the behaviour of just one plant, Lysenko concluded that the plant had passed its spring form to its descendants, in classic Lamarckian style. This was too much for the staff of Vavilov’s bureau (the geneticists), and they began to lobby Vavilov to stop encouraging the kid from Odessa.

The book will really leave you wondering if humanity has learned anything over the past hundred years or is even capable of learning?

As a result of a warming climate, the global water cycle becomes more intensified and as a result wet regions are getting wetter and dry regions are getting drier. The researchers found that this intensification is also reflected in ocean salinity. The increase in ocean surface salinity in salty regions, such as the subtropical oceans, leads to denser seawater and more heat uptake in to the deep ocean. The increase in the rate of ocean heat uptake would reduce the rate of surface warming. 

I’m trying to make sense of this paragraph. Not having much luck. Not sure if it’s due to my ignorance or theirs.
NOTE: the study is paywalled.

What does “more intensified” mean? From previous paragraph it means more surface water is transferred to the deep ocean and vice-versa?

How do they know the intensification is “a result of a warming climate” ?
Where’s the proof that “wet regions are getting wetter…”?
How does CO2(?), warmer temps(?) cause the “increase in ocean salinity in salty regions”? As opposed to non-salty regions?

So saltier means more dense and therefore drops to the bottom of the ocean, being replaced with the colder bottom water?

Therefore the “rate of ocean heat uptake…” So now we have a cooler surface ocean temperature which sucks out more heat from the atmosphere?

And even if this is true especially if this is true, does it not just reinforce the idea that the earth’s climate system has untold # of check and balances?

Thanks for any responses and sorry for so many questions.

It is a favourite trick of the alarmists to quote things like making dry areas dryer and wet areas wetter as if it is fact that is universally accepted when giving background for something else. Researchers who end up with a contrary conclusion (like this one, oceans moderate sensitivity) double down on this rhetoric to be seen as supporting the alarmist narrative while still being able to publish their conclusions. Hence all the goofball statements of “fact” that are alarmist talking points.

In this case they ran a model twice with one parameter being different and have the audacity to call it research.

It’s a water based heat engine, the climate. As it gets warmer it speeds up. And as a heat engine speeds up, it moderates. It moves heat faster from its sources to elsewhere. The fact that warm things move faster is in the neighborhood of a universal. And water is the medium for heat transfer. We’ve known that for a long time.

They do post SI, supplemental information, including graphs.

They use gross assumptions for growth factors in almost every one of their models.

They use NOAA’s Joules instead of Celsius “Global Ocean Heat and Salt Content: Seasonal, Yearly, and Pentadal Fields” to make infinitesimally small numbers appear large.Couple with NOAA’s FLOR climate models, “FORECAST-ORIENTED LOW OCEAN RESOLUTION (FLOR)”
They run models out 200 years using their often incremental gross assumption growth factors.

This is a perfect example of twisted logic. They started with the conclusion (AGW) and tried to figure some way to explain what they were seeing. It is anti-science idiocy at its worst.

I’ve been saying for years that much of the warming we have seen is due to a natural cycle of increasing salinity. It is the driving force. They see it too but cannot state the obvious. So, it must be some sort of convoluted effect of AGW. They wrap themselves into the proverbial knot to ignore science. That his nonsense could ever be published is yet another example of the anti-science nature of climate studies.

When I read that my first thought was, “Are they going to put a legislatively-regulated, public utility corporation in jail for manslaughter?” Or perhaps dissolve (execute) the corporation, denying citizens in the state from having electricity and gas? Or will they fine the corporation, requiring it to raise rates to continue to be solvent, thus effectively requiring the customers to pay the fine? It seems that the democratically controlled state is unclear on the legal definition of manslaughter.

Some years ago now, I considered myself unshockable as to what shortcuts they would not hesitate to employ in the rush for global warming.
Then I read (at Judith Curry’s place, I believe) that the marvellous models didn’t trouble themselves about the fact that the enthalpy of vaporization of water varies by about 5% over temperature ranges commonly encountered in the Earth’s climates.

Paraphrasing, Gavin the Schmidt appeared to be well aware of the issue but was kinda like ‘yeah, whatever, it probably cancels out, and is just too hard anyway’.
He’s a mathematician by training. Plus or minus five percent of a fundamental constant in the most important process in the geosphere troubled him not. I was somewhat dismayed that Judith Curry appeared only slightly concerned that models didn’t bother with such trivia.

Compared with what other physical features models do not bother with, the variation in enthalpy of water vaporisation is below trivia.

I consider their greatest weakness is the lack of mass balance on atmospheric water. Atmospheric water has three independent treatments. Water vapour that is regarded as a greenhouse gas causing warming; evaporation and precipitation that make places dryer and wetter respectively and clouds that can block both sunlight from thermalising in the climate system and long wave surface cooling. These are all independent and not subject to mass balance. The models can create and destroy atmospheric water as needed because there is no continual mass balance of atmospheric water. Clouds can form without water. Precipitation can occur without changing the mass of water in the atmosphere. .Likewise evaporation can occur without changing the mass of water in the atmosphere.

Model have very limited relationship to the physical world. All models can be reduced to a black box with a CO2 knob linked to temperature. Change the CO2 knob causes the temperature to change – they are really that simple; extrapolating the trend observed in the last few decades of the 20th century. None of the models even agree on the current temperature, but most have the same relationship between the CO2 knob and temperature.

Climate models are destroying the credibility of computer modelling. They are a truly sad joke on the entire world; maybe with the exclusion of China. Their FGOALS models has the lowest sensitivity to the CO2 knob.

My best guess is the ARGO buoy fleet. They take salinity data along with temperature. I know of a few expeditions back in the day, where they used sample bottles to retrieve samples from depth. The ARGO record is short and sparse. For the rest of the historical record, “sparse and incomplete” barely begins to cover it.

How they grow their salinity changes for the next 200 years is unknown. They use 1% annual PPM increase and an initial 1.9K° TCR.

Nahhh, simple not possible! I was assured many years ago, over a period of many years by AGW/CAGW “scientists”, that the science was settled on the subject of global warming climate change.

Discovery of new mechanisms that influence the rate of global warming is thus simply not acceptable.

The models match observations over the last few decades well. Well, at least the NASA/NOAA/HadCRUT adjusted, corrected, homogenized, Global Warming Enhanced version of the last several decades. The models are tuned with many parameters set to match the “finished product” temperature record. Then they “hindcast” the past to show how well they have done.

It is the forecasting bit that they have so much trouble with.

It’s a mind game

Common knowledge is that the poleward heat transport works similar to a heat pipe with water as the working fluid. In a heat pipe the working fluid velocity is nearly directly related to the the temperature difference between the input and the output. The next thing that will be discovered is that wheels have to be round to work properly.

Did they happen to check the results of their model with reality?

This is solid emissions from bulls’ backsides to the highest order.

The variation in salinity across the surface in the image simply shows the high evaporation zones where salinity is higher and the convergence zones where salinity is lower – most evaporation occurs at SST of 28C. Warmer locations are convergence zones and get more rainfall so are lower salinity. The high latitudes are net precipitation so also less saline.

In locations with high evaporation, there is an upward flow of water from depth working against the conduction of surface heat downward; the surface is the warmest place. That sets the ocean thermocline.

Higher heat retained in the oceans is an indicator of lower evaporation not more. Lower evaporation slows the rate of transport of cool water in the deep channel from the poles to the ITCZ. The consequence is slight increase in temperature at depth as conduction has more time to transport heat deeper. Thermoclines are set by the rate of downward heat conduction and upward flow of cooler water.

This image shows the process reasonably well:

The high salinity regions either side of the ITCZ show the high evaporation zones. The lower salinity fingers between 500m and 1500m depth below the evaporation zones show the transport channels for high latitude water being transported to the evaporation zones.

It is invalid to claim that weather causes changes in the frequency of wildfires when an unknown but large number of them are caused by arson.
We do not have reliable measurements of “arson change” over the last few decades. Geoff S

A woman was just arrested in California and charged with starting one of the recent fires near Redding. She is suspected of actually being a serial arsonist.

Actually, Environmental Science. (She tutored Biology and Chemistry students though, so maybe?) I have to say, I thought your comment was sarcastic, but no.

Doesn’t even make a very good Faerie Storie – it contradicts itself too much and even a child could see through it

Get A Life boyz & girlz of Miami, dump the computer and venture outside into the real world.
Observe what water does > everywhere you see it doing anything, it is taking heat away from the surface or stopping it arriving in the 1st place

Or, get this, maybe CO2 does not cause much warming if any at all…

Or, you could create some kind of extravagant explanation why your ideas about warming are all wrong but not wrong…

When I was young I was a male model. Until the predictions proved grievously wrong.

In my little corner of the world the last 5 years have been wetter.

“ Intensified water cycle slows down global warming”

That’s what emergent thermal homeostasis looks like.

In their landmark 2016 paper, which climate alarmists are trying to airbrush to oblivion, Zaichun Zhu and colleagues found 25-50 percent of vegetated areas having a longer growing season. This is defined as “greening”. This is specifically due to CO2. By contrast, only 4% of vegetated area was “browning” with reduced growing season.

https://www.nature.com/articles/nclimate3004

So this statement “CO2 makes wet areas wetter and dry areas dryer” is a typical fabrication-flail that just comes off the top of their heads and has no basis in evidence – indeed is flat out contradicted by the evidence.

CO2 is greening the planet, and shrinking deserts such as the Sahara. And it is specifically CO2, not warming, that is having this effect, by significantly increasing the light capture efficiency of photosynthesis (don’t you just love that word!) at the leaf level.

Last year – 2020 – Vanessa Haverd and colleagues clearly demonstrated that increased CO2 in air, not warming, is the “dominant driver” of the plant growth enhancement that is happening worldwide, to the tune of 30% since 1900, and 47% per doubling of CO2. Now that’s a carbon sensitivity that can be believed:

“Consistent with the heat uptake changes, the transient climate response would increase by approximately 0.4 K without this process.

Observed multidecadal changes in subsurface temperature and salinity resemble those simulated, indicating that anthropogenically forced changes in salinity are probably enhancing ocean heat uptake.”

A) They use NOAA’s dubious “Ocean Heat Content, 0-2000 Meters” calculation where the Buoy numbers are so small, well within measurement error bounds, NOAA converted the temperatures measured in Celsius to Joules.

B) They use 1.9K° TCR in their CO₂ Forcing model, out to 200 years in the future. With CO₂ doubling at 170 years forward.
i) Their CO₂ does not show any logarithmic decline in warming.
ii) Their atmospheric CO₂ annual increase is percentage based. The First year’s CO₂ ppm increase is 4.15 ppm and increasing every year afterwards. Yet, one of their alleged findings is that humans are responsible for the CO₂ increase. Confirmation Bias!

C) The primary finding is “transient climate response would increase by approximately 0.4 K without this process”.
i) That is, temperatures would be 0.4K° higher without the ocean subducting those infinitesimal Joules temperature increases. Presumably, the 0.4K° surface temperature increase is the total aggregated 170-200 years in the future.

Summation: It appears this alleged research is to provide excuses why official temperature models run hot.

Models of one sort or another are stacked, using gross assumptions for inputs and annual growth.

through a suite of climate model experiments,

Since when was a climate model an experiment?

(That’s a rhetorical question)

“a suite of climate model experiments”

Talk about an oxymoron ! These people need to be taught that a climate model is a theory, not an experiment !

How many people use a composite of browsers to surf the web? Is Microsoft Windows composed of an average of operating systems? Do they have teams of programmers creating operating systems which they then average to create the ideal operating system?
Averaging computer program models is like averaging temperatures, both are affronts to both man and nature.

From the article: “Global warming from emission of greenhouse gas into the atmosphere is increasing sea levels and resulting in more frequent and intense storms, drought, and wildfires.”

None of that is true.

This is great news. All we need to do now is to desalinate water to end droughts and then dump the salty brine back into the sea to end global warming.

Should be simple to do with solar and wind powered desalination plants. I wonder why politicians haven’t promoted it.
