Using future projections from the latest generation of Earth System Models, a recent study published in Science Advances found that most of the world’s ocean is steadily losing its year-to-year memory under global warming. 

Compared with the fast weather fluctuations of the atmosphere, the slowly varying ocean exhibits strong persistence, or “memory”, meaning the ocean temperature tomorrow is likely to look a lot like it does today, with only slight changes. As a result, ocean memory is often used for predicting ocean conditions. 

Ocean memory decline is found as a collective response across the climate models to human-induced warming. As greenhouse-gas concentrations continue to rise, such memory decline will become increasingly evident.

“We discovered this phenomenon by examining the similarity in ocean surface temperature from one year to the next as a simple metric for ocean memory,” said Hui Shi, lead author and researcher at the Farallon Institute in Petaluma, California. “It’s almost as if the ocean is developing amnesia.” 

Ocean memory is found to be related to the thickness of the uppermost layer of the ocean, known as the mixed layer. Deeper mixed layers have greater heat content, which confers more thermal inertia that translates into memory. However, the mixed layer over most oceans will become shallower in response to continued anthropogenic warming, resulting in a decline in ocean memory. 

“Other processes, such as changes in ocean currents and changes in the energy exchange between the atmosphere and ocean, also contribute to changes in ocean memory, but the shoaling of the mixed layer depth and resulting memory decline happens in all regions of the globe, and this makes it an important factor to consider for future climate predictions,” said Robert Jnglin Wills, a research scientist at University of Washington in Seattle, Washington, and co-author of the research.

Along with ocean memory decline, the thinning mixed layer is also found to increase the random fluctuations of the sea surface temperature. As a result, although the ocean will not become much more variable from one year to the next in the future, the fraction of helpful signals for prediction largely reduces. 

“Reduced ocean memory together with increased random fluctuations suggest intrinsic changes in the system and new challenges in prediction under warming,” said Fei-Fei Jin, an atmospheric sciences professor at the University of Hawai‘i at Mānoa School of Ocean and Earth Science and Technology, and co-author of the research.

Ocean memory loss doesn’t just impact the prediction of physical variables, but could also influence the way we manage sensitive marine ecosystems. 

“Reduced memory means less time in advance for a forecast to be made. This could hinder our ability to predict and prepare for ocean change including marine heatwaves, which are known to have caused sudden and pronounced changes in ocean ecosystems around the world,” said Michael Jacox, a research scientist at NOAA Fisheries’ Southwest Fisheries Science Center in Monterey, California, and co-author of the research. 

In fisheries management, the biological parameters used for stock assessment are estimated assuming a stable environment represented by the recent past. Reduced ocean memory might render such estimation inaccurate and calls for new approaches in ecosystem-based fisheries management to include real-time ocean monitoring and other efforts alike. Ocean memory decline also likely exerts impacts on populations of biological resources. Depending on whether the species are adapted to constant or more variable environmental conditions, future changes in their population can be better estimated and predicted by taking ocean memory loss into consideration. 

Besides ocean prediction, forecasting land-based impacts on temperature, precipitation as well as extreme events might also be affected by ocean memory decline due to their dependence on the persistence of sea surface temperature as a predictability source. As ocean memory continues to decline, researchers will likely be challenged to search for alternative predictors for skillful predictions.

much more important & revealing metrics. Within a day, a post shows how the The Team™ lied
about ocean data & gave a basic concept a meaningless woke name. That’s the same old stuff,

I couldn’t make it past the first few paragraphs. The scientist had a lot of bad luck and tragedies just before the pandemic and somehow it segued to her being people’s climate therapist – how to stay positive when faced with all the damage.

Here’s a better way than trusting a climate bedwetter activist with making one feel better about the environment – do some actual research and digging to find out what is really going on and stop listening to the muck raising media.

If we know that the recent 3My have been the coldest of the last 200My can we presume that oceans didn’t have memory most of the time. But if you have a colder climate like between two interglacials temperature fluctuations become even bigger. What does that do with the ocean memory. What about La Nina El Nino events ?

That’s a bit of a problem, these forecasts are what’s remembered. Particularly in this sort of case when a rebuttal can take weeks or months and is not published in the gutter press,

A lot of predictions by the Met Office have been published in national and local press in the UK over the last two or three weeks, it’s yet to materialise in Derby. But what people remember is that a heatwave was forecast so it must have happened. I’m not a conspiracy theorist so I put it down to ineptitude of the MO and incompetence of the press and Gullibility of a large section of the public

So they found the effect by examining models of predicted future ocean warming rather than looking at actual ocean conditions over the past 40 years…. it’s as if they knew they could only find what they were looking for in models.

Well the actual article does point to research that indicated a drop of about 5% over 6 decades in however they measured stratification.

But that study only found that extra stratification by going to a depth of 2000m instead of the 200m that they said was previously used.

I found that fishy, since the layer these scientists are panicking about is only 50m, and it was only a change of .9% per decade and most of the changes in the more recent decades – when temperatures have been relatively flat since after the 1998 El Nino.

The stratification seems mostly determined by salinity differences, and while the Arctic reduction in sea ice extent added lots of fresh water, that extent seems stabilized now, and anyhuge differences eventually even themselves out with continued mixing.

I think this is going to be another case of climate scientists noticing a symptom and turning it into a disease. Salinity and stratification leading to… something instead of being just a transition to a new equilibrium level; CO2 levels increasing to set the world on fire, instead of just being the result of coming out of the Little Ice Age since the depth of the cold in 1700.

Models!

I thought, what does ARGO observe? Found a perfect on point paper in GRL at 2017GL073426 titled ‘An ARGO mixed layer climatology’. Built from about 1250000 separate ARGO profiles from 2003 to 2017, and computed two ways. The complete database with computed mixed layer depths (MLD) is available at http://mixedlayer.uscd.edu.

Turns out the MLD has a strong seasonal component—shallower in summer. Hence the climatology. Turns out that it also varieties geographically (deeper in the turbulent Southern ocean) and annually. But based on the paper’s database, and Fig. 3b for the Labrador Sea, there is NO general shallowing caused by global warming over the period to 2017. NONE.

It is only in climate models of what the future might be. Another bogey man lurking under the warmunist bed.

Of course they didn’t look at the paper you cited (btw the link doesn’t work) but found another that does, sort of (.9% increase in stratification per DECADE and they had to change the methodology, by looking down to a depth of 2000m, to find even that much.)

So decades of ocean measurements that did not show this “memory loss” suddenly are negated because models. Based on an assumed climate sensitivity to CO2 that is likely far higher than the actual climate response. Every one of these stories just reads like bullshit being peddled in order to get another round of funding.

Modeling has a place in science. The problem is that the current generation of scientists has elevated the importance of poorly understood physical systems, as expressed in computer models, above the importance of empirical observations. More data might be able to improve the models, but everyone seems to be too busy cranking out predictions from the existing models to gather the much needed data.

 “Ocean memory loss doesn’t just impact the prediction of physical variables, but could also influence the way we manage sensitive marine ecosystems. ” I guess that without a memory, literacy is not possible. Didn’t teach such courses when I took and even taught a little oceanography. Learn something new every day!

Special Issue: Future Seas 2030: Pathways to Sustainability
Reviews in Fish Biology and Fisheries  https://futureseas2030.org/ &nbsp;
Ocean literacy experiential learning.  “When we dance the ocean, does it hear us Equity of our future oceans: practices and outcomes in marine science research” Trying to outdo the water striders out there? Ocean & atmosphere boundary layers are quite a place, easier and maybe more fun to study other aspects.

From the paper, first in abstract– “This global decline in ocean memory is predominantly driven by shoaling of the upper-ocean mixed layer depth in response to global surface warming, while thermodynamic and dynamic feedbacks can contribute substantially regionally.”

First line in Introduction– “More than two-thirds of Earth’s surface is covered by ocean,….”
In Results–“The 1-year autocorrelation of annual mean SST anomalies [hereafter referred to as A(1)] is used as a simple metric of the year-to-year ocean memory (Materials and Methods). The SST anomalies are defined as deviation from the long-term trends (Materials and Methods) ….. Just as the shoaling of the MLD is the main reason for the decline in ocean memory, it is also the reason for the increase in noise variance (Materials and Methods).” MLDs (Mixed layer depth) SST (Sea surface temperature for those of you that didn’t know about the size of the ocean).

Materials and Methods “ We use CMIP6 output of SST, MLD, surface latent heat flux, surface sensible heat flux, and surface radiative fluxes from the preindustrial control simulations, historical simulations, and various SSP (65) scenarios, including SSP2-4.5, SSP3-7.0, and SSP5-8.5. We selected a total of 20 CMIP6 models…..”  

I suppose that we had some memory about noise variation back then, and they did show in their references that there actually were some thermodynamic measurements made in the last millennium. I also learned about another NOAA program (Modeling, Analysis, Predictions, and Projections ). They need to go to sea and measure some real (not so sensitive and autocorrelated) thermoclines!

Gentle correction. You confound two different things.

The deep ocean overturning is how long it takes very cold and very salty from sea ice formation exudate (thus heavy) polar winter water sinking to the ocean bottom to resurface as an upwelling somewhere. Estimates vary, but your 1000 years is a good central estimate (estimated range 1200-800).

The mixed surface layer depth isn’t polar except in high summer. It is the euphotic surface (sunlight penetrating biologically relevant photosynthesis zone, condition dependent about 80 to no more than 150 meters), plus whatever might lie just below in similar temperature and salinity conditions due to wave action turbulence mixing. So inherently deeper in the southern ocean ‘roaring forties’ and ‘screaming 50s’.

The ocean is losing it’s memory

In this case I think this will be difficult to trace back to the primary cause.

Do the most obvious and important things first.
They need to do a multi-variate study to determine if simple old age is the primary cause.
Simple aging is far and away the most common cause of memory loss.

… and these dummies are university academics?!
Oceans do not have memory, they have thermal capacity, I would be tempted to call it ‘thermal hysteresis’ (the phenomenon in which the value of a physical property lags behind changes in the effect causing it, whereby down cycle may not follow rate path of the preceding up cycle, e.g. oceans may not cool and heat at the same rate).
Also oceans might be subject to long term natural cycles, such as centenary or millennial solar cycles, the millennium+ long great conveyor belt cycle, AMO and PDO cycles whose causes are not entirely certain. I believe there also some long term tidal cycles that might affect temperature behaviour of costal waters, i.e. the whole panoply of cyclomania, you might say (: .

I agree, and I want to add that scientists will generate bogus predictions when trying to simplify a process like the oceans’ thermal capacity by pretending it’s memory – exactly the same bs they are doing by treating the lapse rate affected by CO2 levels as “downwelling radiation” or “CO2 forcing” – unjustified simplification, especially if they persist in prophesying a century in the future.

while talking about the uppermost layer of the ocean, they state “Deeper mixed layers have greater heat content”
I need to learn something here as I thought it got colder (less heat content) lower down
?

Lower temperatures, but greater volume.

Once again, “scientists” who wrote this article confuse the output of theoretical climate with physical evidence. They write as if they had discovered some facts about the real world.

Instead, they have only added to quantification of their theories. Only real world measurements can confirm or deny theory or projections of theory. Scientists used to understand this.

The language in the article should be only in the “if….,then….” mode, not the “We find…” mode.

This article is not science.

My gawd, this sounds exactly like something a so-called “scientist” from a non-science background would say, turning the oceans into mental patients who are suffering alzheimers.

A real scientist would never resort to using such goggledygook bullshit terms.

The real scientific terms include concepts like the specific heat capacity of liquid water, and the comparative mass of the oceans to the mass of the atmosphere. And the various laws of thermodynamics.

….that’s all too difficult. It involves math.

Using future projections from the latest generation of Earth System Models, a recent study published in Science Advances found that most of the world’s ocean is steadily losing its year-to-year memory under global warming.

Sounds like an issue with the models; I don’t see anywhere claiming this behavior occurs in the real oceans. We’ve had 3,000 operational ARGO buoys since late 2007. You’d think if there was a trend in year-to-year temperature you could find it in almost 15 years of reasonably comprehensive data. Instead, they examine model outputs.

If models are all you have then we can discuss what they purport to show. But if you ignore real data to consider only models, you might as well be reading Tarot cards.

Title of above article:

“Claim: World’s Ocean Is Losing Its Memory Under Global Warming”

Heck, that’s nothing . . . most of industrialized Western nations, the IPCC, the Biden administration, and the MSM have lost their collective minds over Global Warming.

they made a big mistake! They used nice cool blue on there graphic, it doesnt look menacing like a nice dark red does.

Ocean losing its memory? Research grant seekers losing their minds.
