Cooling trends of up to -2.15°C per decade are not consistent with the “global warming” narrative.
According to a new study (Li et al., 2025), 98% of the Central Eurasia study area (40-65°N and 50-130°E) experienced significantly declining temperatures from 2004-2020.
Specifically, the region cooled by nearly -2.0°C – a rate of -1.425°C per decade – from 2004 to 2018.
The authors attribute the cooling trend to a 5.38% per decade increase in snow cover percentage (SCP) across the study area.
We reported here on the circumstances that caused the Spain Blackout last month: oscillations in a controlled system that were built up and contained too few integrative components, which had previously prevented this from happening.
This is mainly due to the increasing number of inverters that photovoltaics (PV) are introducing.
They have practically no inertial elements, as was the case before the many PV with rotating masses of large turbines. This is the obvious and, from a control perspective, completely clear indication of “too many” inverters synchronized only to the 50 Hz of the power grid. There are also technical solutions that prevent this: An external frequency standard as a “target frequency”, phase-locked at all feed-in locations (regardless of how the generation takes place) and “disciplined” with GPS. Such an arrangement is described here.
Of course, retrofitting is not cheap and takes time. However, the electricity grid would be more resilient and a possible “black start” after a blackout would be much easier to manage and much quicker.
To date, we have heard many opinions and “snap judgments” about the cause and future prevention of such incidents.
We reported here that there is a political focus on more electricity storage in Spain. Something like this will also take decades (if the required quantities ever become sufficient) and by then a bomb will be ticking.
Now, political decisions are simply political and initially do not help the electricity grid at all. That’s where control technology comes in and it has no convictions or party memberships.
So what would a technician do if it was clear that too much PV (with the associated inverters) was one of the causes of the blackout? Correct, he would reduce the share of electricity production. Anything else would be illogical.
What was actually done? The daily data from here can help. A look at the share of PV and nuclear power in daily electricity production in Spain around the time of the blackout on April 28th:
Share of power generated, nuclear (Kernkraft) and solar.
For PV (solar), the average share was 27% until April 27, and only 20% thereafter.
The downward trend is highly significant. In contrast, the share of nuclear power increased slightly, but has an upper limit: its installed capacity. Almost everything that was available in terms of integrating components (= inert masses) was activated. The “fast” inverters were reduced. The total PV output fell from an average of 182 GWh/day to 127 GWh/day. PV was therefore reduced by around 30% after the blackout in Spain. This is logical and speaks for itself.
All (political/ideological) attempts to blame something else for the blackout in Spain must be dashed by these clear realities. So no matter what little soup is tried to be cooked, technology can neither be persuaded nor fooled.
If you look at the climate website of the Helmholtz Association with the ambitious name “Climate Facts” under Antarctica, you will read the following: “The important mainland ice of Antarctica is disappearing, and at an increasing rate”. According to the Helmholtz Association, this is of great significance for rising sea levels. And indeed, the rising sea level caused by the melting Antarctic ice is one of the central arguments of climate policy that has worried people.
This makes the result of a recently published study, according to which the picture has changed since 2021, all the more surprising: Antarctica’s continental ice is increasing again.
Chinese researchers from Tongji University led by Prof. Shen and Dr. Wang found that Antarctic ice masses have increased significantly since 2021. The data evaluated by NASA’s GRACE satellite showed an annual loss of 74 billion tons per year from 2002 to 2010. From 2011 to 2020, the amount even doubled. Now the ice has increased by around 108 billion tons year on year.

As the melting of the Antarctic glaciers contributed around 20% to sea level rise, a slowdown in the rise has been observed since 2021. Wouldn’t this good news be worth reporting on the news? Not so far.
A second piece of good news is also not being reported by the German Tagesschau news or political Berlin: Arctic sea ice has not decreased for over 10 years. A recent publication by Mark England from the University of Exeter and Lorenzo Polvani from Columbia University in New York has drawn attention to this. The researchers report that the decline in Arctic sea ice is expected to pause for decades. They expect it to continue for at least the next 5-10 years.
As recently as 2009, John Kerry, US climate envoy, sounded the alarm that the Arctic would be ice-free in 2013. The reality turned out differently:
The decline in Arctic sea ice up to 2012 is well documented by satellite measurements, as is the subsequent stabilization and slight recovery. The annual September minimum is used for comparison. Following the strong warming of recent years, a renewed decline was expected. But the sea ice remains stable.
Climate model forecasts are increasingly deviating from reality. Axel Bojanowski spoke to two scientists from the Max Planck Institute for Meteorology in Hamburg. Prof. Bjorn Stevens and Prof. Jochem Marotzke speak of a crisis in climate science. Marotzke: “The current class of climate models is running into too many contradictions with reality”. Marotzke is concerned about the great uncertainty of the models. He cites the following examples: “In large parts of the world, the models contradict each other on the question of whether it will rain more or less in the future. The warming of the Earth’s surface between 1998 and 2012 was significantly slower than predicted by the models (“hiatus”).
Since 1979, the tropical eastern Pacific has cooled, contrary to the expectations of all models that simulate warming there.”
With regard to climate science, Marotzke speaks of “the other climate crisis”. “This is the moment for a paradigm shift”
These statements are based on climate models for which, according to Marotzke, we now need a paradigm shift because they no longer reflect reality with sufficient accuracy after just a few years.
When will there be a paradigm shift in climate policy in this country?
DNA evidence suggests the limit of Antarctic sea ice was ~2000 kilometers farther south than it is today 2500 to 1000 years ago.
Elephant seals can only breed in the Southern Ocean’s subantarctic, sea ice free waters. For example, today’s largest colony breeds on Macquarie Island (54.5°S).
Scientists (Wood et al., 2025) have now identified DNA evidence of an elephant seal breeding site at Cape Hallett (72.3°S), with the remains dating to the Roman and Medieval Warm Periods (2500 to 1000 years ago).
Cape Hallett is approximately 2000 kilometers south of the southernmost modern elephant seal breeding grounds. This means Antarctica’s sea ice limits were thousands of kilometers less extensive than today’s back when CO2 concentrations were at “safe” pre-industrial levels (~265 ppm).
A 2019 study indicated Late Holocene elephant seal remains can be found even farther south along the Ross Sea coast than Cape Hallett.
For example, elephant seals occupied breeding sites on Inexpressible Island and Marble Point (77.4°S) from 2000 to 1000 years ago. This means Late Holocene sea ice free latitudes extended 2400 kilometers farther south than today’s.
“…land-fast ice and multi-year sea ice has become much more pronounced in coastal settings over the last millennium.”
The French are finding out that combining nuclear power with unstable wind and sun is not a good idea and is a risk to the power grid. Spain recently had to learn a similar lesson in a most painful manner.

In a recent EDF report on nuclear safety, Rapport de l’Inspecteur Général pour la Sûreté Nucléaire et la Radioprotection, lead author and former admiral Jean Casabianca concluded that a further expansion of wind and solar energy in France poses serious risk to the country’s power grid.
According to the report, the instability of a weather-dependent wind and solar power supply is a technical and financial burden to nuclear power in France.
Page 13 of the report states:
The massive arrival of new renewable electricity sources (RE), both intermittent and a priority on the grid, has multiplied load variations.
They are not without risk to the safety of the power system (including blackouts), nor are they without constraints on the operation of our facilities. In the long term, they call into question our economic model. (…)
Modulation has gone from flexibility to constraint, with nuclear power having to meet demand alone or in conjunction with hydropower, unless we resort to using thermal and carbon-intensive means.
In addition, load following inevitably has an impact on the machine, which is more frequently solicited by deep cycling. The increase in fortuitous events is not obvious, but it’s over time that the effects will be appreciated.
I believe that the priority given to renewable energies, in a unilateral nuclear-Renewable Energies scheme, leads to power variations which it would be all the more opportune to dispense with, as they are never insignificant in terms of safety, particularly reactivity control, and the maintainability, longevity and operating costs of our facilities.”
Many previously claimed that the nuclear industry could be harmoniously paired with wind energy and thus lead to a decarbonized French electricity mix. But that is proving to be more fantasy than reality. The recent Spanish blackout was a glaring example of what can happen when ideology clashes with hard science and reality.
Many engineers and specialists had warned of the risks and complications involved with nuclear power plants having to adapt their output to uncontrolled, fluctuating energies like wind and sun.
In the global energy war being waged in France by this pro-wind and pro-photovoltaic lobbying that is contrary to France’s energy interests, this discreet report strikes a real blow to France’s intermittent energy policy. Even if energy and political players haven’t yet fully grasped the significance of this historic technical report, there’s no denying that it will be a landmark and cannot be buried or downplayed by EDF CEO Luc Rémont.”
According to a new study, the recent short-term (2011-2022) decreasing Antarctic sea ice concentration (SIC) trend has not offset the overall 43-year (1979-2022) trend of increasing Antarctic SIC.
The strongly negative sea surface temperatures and SIC correlation coefficient (-0.73) indicates the waters around Antarctica have undergone a long-term cooling trend.
Recent studies shows that the Arctic and Antarctic have cooled over the past 2 decades, and that ice mass has gained in the Antarctic Wilkes Land-Queen Mary Land region.
In the period of 2002-2010, there was moderate ice loss of -73.79 ± 56.27 gigatons per year, which contributed to 0.20 ± 0.16 mm per year to global sea level rise.
From 2011-2020 there was almost twice as much ice loss of -142.06 ± 56.12 gigatons per year, contributing 0.39 ± 0.15 mm per year to global sea level rise.
But in the period of 2021-2023, there was a surprising a mass gain of 107.79 ± 74.90 gigatons per year that offset global sea level rise by 0.30 ± 0.21 mm per year.
Cooling at rate of 5°C per century since early 1980s
In a study published in 2023, “Significant West Antarctic Cooling in the Past Two Decades Driven by Tropical Pacific Forcing”, authored by Xueying Zhang et al, analyses showed that the West Antarctic cooled over the past 2 decades: “In particular, during 1999–2018, the observed annual average surface air temperature had decreased at a statistically significant rate, with the strongest cooling in austral spring.”
The results show that most of the Antarctic continent has cooled by 2 °C since the early 1980s. That translates into a rate of 5°C per century.
The Surface Mass Balance (SMB) for the Antarctic Ice Sheet (AIS) has been remarkably stable since the 1970s.
However, according to the authors of a new study (a preprint soon to be published), “in recent years, the SMB has increased on the AIS, in particular for 2022, which mostly originates from mass gain on the EAIS.”
Once considered a key technology in the green energy transition, companies are waking up and finding out that hydrogen isn’t the answer to the challenges posed by renewable energies such as wind and sun.

“Instead of progress, disillusionment dominates. The EU in particular – especially Germany – is increasingly being criticized for its costly projects,” reports German online Blackout News. “Companies are pulling out”.
Hydrogen is expensive, hazardous and a real technical challenge that doesn’t promise to be economically feasible. The gas is metallurgically aggressive, highly flammable, explosive. It’s chemical properties make a comprehensive infrastructure difficult to manage. Moreover, producing green hydrogen is “barely affordable” and industries are reluctant to use the volatile gas because it risks being unprofitable.
High costs, low demand and political misplanning are currently jeopardizing the strategy, according to an analysis by Westwood Global Energy Group. “Only a fraction of the planned EU hydrogen pipeline is likely to be operational by 2030.”
Germany has funded an ambitious green hydrogen project in Namibia, in a protected desert area and now it may be demolished for port expansion as the country’s new president is reportedly reassessing the project and looking at a potential shift towards the established oil sector. Technical analyses indicate hydrogen is only suitable as a selective energy source.
Unless there is a major change of course, the EU’s hydrogen strategy risks being a costly failure.
A new surface air climate reconstruction method (Roberts et al., 2025) has determined neither the entire region from 60-90°S (Southern Ocean, Antarctica) nor the continental US have undergone any unusual or unprecedented warming in the modern era.
The 60-90°S region had much warmer-than-modern periods throughout the last 12,000 years.
Yet another region of the globe has failed to cooperate with anthropogenic “global” warming narrative.
According to climate models constructed on the presumption that CO2 concentration changes are the driver of climate, Central Africa should have been warming in recent centuries in tandem with the rise of atmospheric CO2.
However, scientists (Ménot et al., 2025) using brGDGT (branched glycerol dialkyl glycerol tetraether) proxies to reconstruct paleo temperature trends have determined the Cameroon region test site is likely colder today than any other time in the last 7000 years.
Mean annual air temperatures (MAAT) are 22°C at the study site today. About 7000 years ago, when CO2 concentrations were ~265 ppm, MAATs were 24.5 to 25.5°C, or at least 2.5°C warmer today.
As CO2 levels rose throughout the Mid- to Late-Holocene, temperatures continued to decline. This negatively correlated trend is the opposite of model predictions.
“A 2.5°C temperature drop in 7000 years exceeds current model predictions.”
Hans-Joachim Dammschneider has written a book about the climate history of the southern Harz region. In the historical weather data, he discovered climatic fluctuations that, according to the Intergovernmental Panel on Climate Change (IPCC), should not exist.
Long before industrial CO2 accumulated in the atmosphere, there were already alternating warm and cold phases.
Here is the book description:
The so-called Medieval Warm Period (MWP) has been the subject of scientific debate for years. It is not so much a question of whether this warm period actually took place in Europe, but rather how it took place. Was it a local phenomenon that was limited in time and predominantly restricted to Europe, or was it a period of intense climatic change that also had a global impact?
One thing is certain: from around 950 AD, there was a rise in temperature in Germany lasting at least 300 years, which resulted in a marked warm phase favorable to agriculture and life. However, from the beginning of the 14th century at the latest, this period was replaced by a relatively rapid drop in temperature and climatic turbulence in the direction of the so-called Little Ice Age.
In the early reports, the IPCC (1990, AR1) still devoted relatively much attention to the MWP. Over the years, however, this focus diminished, and in the most recent assessment (2021, AR6) little space was given to the Medieval Warm Period. Studies often even question whether it was a global phenomenon. However, a mapping of the available scientific publications (as of 2022) initiated by S. Lüning shows that the Warm Period certainly left evidence across continents.
From the perspective of natural and cultural history, many accounts show that Germany was in a phase of intense cultural and economic growth from around 1000 AD. This period is characterized by the founding of numerous towns, the expansion of agricultural land and strong population growth. Forests were cleared, building methods influenced, and rising temperatures and the resulting positive agricultural economy contributed to prosperity.
Of course, there were no scientific methods for recording the weather, but modern climate research uses so-called “proxies” to derive the climate parameters of the time. For example, the cultivation of figs north of Cologne, successful wine production as far as Schleswig-Holstein and (overall) the PFISTER index resulting from numerous features indicate a longer phase of mild temperatures and favorable climatic conditions. Climate-numerical backward simulations basically confirm this ‘warm period’.
Historically, such periods were often periods in which life flourished – an idea that plays a rather ambivalent role in the climate debate for the 21st century.
The example of Walkenried Monastery and the southern Harz monastery landscape shows the solid consequences of the MWP: the reclamation of swampy areas, the development of the Upper Harz water management system, the promotion of mining and the intensive use of wood for construction and energy purposes are just a few examples.
However, this phase of monastic prosperity between 1130 and 1300 AD was apparently brought to an end by a rapid drop in temperature. The onset of the ‘Little Ice Age’ brought very uncomfortable weather conditions that lasted until the end of the 18th century. As early as the beginning of the 14th century, the country was hit by destructive rainfall and floods (“Schluchtenreisen” / Magdalenenflut), failed harvests followed intense droughts (Dante anomaly) and devastating plagues with millions of deaths in epidemics partly destroyed social structures. These instabilities and hardships, which were not least determined/induced by the climate, certainly had devastating effects on the livelihoods of the monasteries in the southern Harz region. They led to considerable internal crises (including the loss of converts and lay brothers) and ultimately the end of the Walkenried monastic ‘group’ (with the abandonment of large areas of the Harz ore mining industry) in the 15th century.
If this was the case, what overarching climatic processes contributed to this? It can be assumed that, in addition to temperatures, other factors such as the duration of sunshine also played an important role in the living conditions: The sun indeed seems to have been ‘the’ factor of the MWP, whereas CO2 is that of modern times … .
Recent analyses and the AMO (Atlantic Multidecadal Oscillation) index, which can be traced back to 900 AD, indicate that cyclical SST (Sea Surface Temperature) energy influences from the Atlantic could have significantly influenced cloud cover and thus sunshine duration and temperatures in Europe. These interactions were also important for the southern Harz and Walkenried. Can evaluations of current climatic processes indirectly allow conclusions to be drawn about past physical and social changes with associated phases of ascent and descent between 1000 and 1400 AD?
The present study examines these questions and attempts to draw conclusions for the interactions of the medieval climate from large-scale processes of potential ‘teleconnections’ and oceanic cycles. The book is intended, among other things, as a sequence of steps that helps to better understand the complex interrelationships of medieval climate change. It shows which ‘natural’ parameters could have contributed to the rise and fall of Walkenried Monastery.”
