The recently from Tselioudis et al. It offers another memory that so -called “defined science” in climate modeling is anything but done. In fact, it accidentally shows how fragile the predictive power of climate models is, especially when it is shown that basic atmospheric processes such as cloud cover are both more dynamic and less understood than previously claimed.
Not that something of this is news for WUWT readers. Dr. Roy Spencer has noticed almost identical observations for over a decade, as mentioned here.
Now let's take a look at the broader scientific community that Dr. Catched Spencer.
Abstract
The latest observations of the earth's budget show an increase in sunlight, which was absorbed by the earth of 0.45 W/m2 per decade, which is mainly caused by a decrease in the cloud reflection. Here we break down the budget trends of solar radiation into the general components of the distribution and cloud control. Regime, which represent the zones with medium -sized latitude and tropical storm zones, are defined, and the trends when covering the area of ββthose regimes that may be induced by circulatory changes are separated from trends in the cloud radiation effect in every regime, which may be induced by changes in the local cloud control processes. The change component of the regime area, which manifests itself as a contraction of the midlatine and tropical storm regime, forms the largest contribution to the solar absorption trend and leads to reduced sunlight of 0.37 W/m2 per decade. This result provides a crucial missing piece in the puzzle of the 21st century increase in the sunscape of the earth.
Key points
- Satellite observations show that in the past 24 years the world storm zones of the world have combined at a speed of 1.5% β3% per decade
- This contraction enables more solar radiation to reach the earth's surface and forms the greatest contribution to the observed trend of the 21st century of an increased solar absorption
Summary of the simple language
The analysis of satellite observations shows that in the past 24 years the storm cloud zones of the earth in the tropics and the middle latitudes have been brought together at a speed of 1.5% β3% per decade. This cloud contraction decreases together with the cloud cover with low widths and enables more solar radiation to reach the surface of the earth. If the contribution of all clouds of clouds is calculated, it is determined that the storm cloud contraction in the 21st century is contributed to the observed increase in the sun's sunscape.
In order to understand the full effects of this study, we have to analyze your results in clear terms. The paper comes to the conclusion that the earth has absorbed significantly more solar radiation in the past 24 years – 0.45 W/mΒ² per decade. The main culprit? A reduction in the cloud cover, in particular a contraction of the zones with medium latitude and tropical storm clouds. This change has caused less solar radiation to be reflected back into the room and more absorbed by the earth's surface. It is crucial that 0.37 W/mΒ² of this increase can only be attributed to this contraction in the cloud cover. This is a result of a large scale in atmospheric circulatory changes:
“This cloud contraction decreases together with the cloud cover in low widths and enables more solar radiation to reach the earth's surface. If the contribution of all clouds of clouds is calculated, it is determined that the storm cloud contraction makes the main ratio to the observed increase in the sun absorption of the earth in the 21st century in the 21st century.”
Let's pause there. Climate science has long emphasized the role of anthropogenic greenhouse gas – especially CO2 – when taking the outgoing long -wave radiation, which contributes to the heating of the surface. Here, however, we have empirical satellite observations that show that changes in short -wave radiation absorption dominate the latest trends in the energy weight of the earth due to the cloud dynamics. This revelation alone should be enough to shake the basics of climate policy that trillions in carbon control have given little attention from the cloud feedback mechanisms.
It is still more damnable that these changes are probably bound to “general circulation shifts”, especially on bar -related movements of storm traces and contractions of the intertropical convergence zone (ITCZ). These are phenomena that are suspected in model projections for a long time, but never such a central, quantifiable role in the planetry energy. And here is the kicker: these circulatory shifts should gradually have appeared at 1.3% to 3% per decade:
“In all three zones, the surface cover of the L -TCC regime shows statistically significantly significant with extremes from 1.84 Β± 0.38% to 3.20 Β± 0.97% per decade … which indicates a contraction of the storm regions with medium latitude and a narrowing of the ITCZ ββregion.”
These are not theoretical projections – they are based on hard satellite data from the instruments of modis and ceres. In contrast, models have only roughly indicated these changes and often do not reproduce them with consistency.
The paper describes that most of the SWCRE (Shortwave Cloud radiation effect) changes – the key measure in which the solar energy is reflected through clouds – is not of changes in the cloud characteristics itself, but from the shrinking geographical area of ββthe most important cloud regime:
“In all zones, the dominant trend is the SW cloud radiation heating, which results from the contraction of the S -SWCRE regime and the corresponding expansion of the W -SWCRE regime.”
This is the type of subtle feedback mechanism with a high lever, the models tend to make, incorrectly or underrepresented. And that's a problem. Because if your model cannot simulate the cloud regime shifts exactly -which seems to contribute more than 80% of the increase in sunny -your forecasts for future warming at best are incomplete and worst in the worst case very misleading.
Tselioudis et al. Even admit this shortcoming and notice:
“It is essential to test the skills of climate models in the simulation of the observed contraction between the storm and black and to use both modeling and observation analyzes in order to understand the interactions between the shifts of atmospheric dynamic and storm cloud changes.”
This is a bureaucrat for “We haven't seen it, and we are not sure whether our models can catch up.” It is reminiscent of Gavin Schmidts from NASA of NASA to “inexplicable” heat tips over 2023, which indicates that “we can be in an unknown area”. Now we have the diagram. And it does not only indicate CO2 to dynamic, cloud-controlled changes that do not stop any carbon tax.
What this paper accidentally confirms is the unreliability of the use of long -term climate models to dictate aggressive, disruptive guidelines such as NET zero. In the models, important physical processes cloud behavior, aerosol effects and large-scale atmospheric shifts are missing. As the paper notes:
“The general circulatory shift component represents the dominant concept of the recent increase in the absorbed solar radiation and offers a decisive missing piece in the puzzle of radiation heating of the 21st century and the large heat anomaly of 2023.”
However, these shifts begin to understand and their driving forces – whether natural variability, solar activity, oceant or a certain interaction from being nailed down.
Even worse, the authors speculate that cloud reductions with low width could be driven by aerosol changes-especially by the decline in ship emissions:
“This component shows a significant heating of 0.21 W/mΒ²/decade, which is due to aerosol indirect effects on clouds, including the effects of the reduction of the aerosol ship emissions.”
This is correct: the same well -meaning effort to reduce pollution from sea ships may have accelerated the warming by increasing more sunlight on the surface. Climate reduction strikes again.
Overall, the paper from Tselioudis et al. A quiet revolutionary work – not because it introduces a new alarmist story, but because it destroys the prevailing distability. It shows that:
- Cloud feedback, especially those driven by shifts by circulation, have enormous and previously underestimated effects on the radiation balance of the earth.
- These changes are powered by complex, poorly understood dynamics that have to replicate current climate models.
- Political decisions based on “defined science” were made without understanding a main component of the grounding agency system.
If climate science were more of a functioning scientific discipline than priesthood, this paper would trigger an important course correction. There would be doubts about the simple connection between CO2 and heating and redirection of the focus on cloud physics, ocean atmospheric interactions and circulation dynamics. It would promote humility in view of the atmospheric complexity – not the arrogance that resulted from model editions.
But don't expect that soon. Instead, you can expect that the usual suspects will turn this as evidence of “worse than we thought”, and made the part in which their models did not predict it and their guidelines did not predict.
In the meantime, this paper should serve as a ammunition for every skeptic that indicates the absurdity of building trillion dollar guidelines on the back incomplete and extremely exclusive simulations. The cloud regime change. The models do not keep up. And the story is not either.
