 An excellent paper by two very known physicists (Princeton and York universities). Very well explained, but you should know your graduate physics!
The authors show that an atmosphere with GHG will have a convective troposphere. They conclude: "Increasing carbon dioxide will cause a small additional warming... best estimate it is about 1C warming for every doubling of CO2 concentration, when all feedbacks are correctly accounted for".

newcleo is a new company which develops a new small fast breeder lead-cooled nuclear reactor; this could use MOX fuel made from radioactive waste from PWR reactors. The main scientist worked at the French Superphénix project, which was a sodium-cooled breeder (link).

Read this interview in Power Magazine on this very promising Gen-IV type of small and modulable nuclear fast neutron reactors.

Did you know that undersea power cable problems cause 80% of the financial losses in offshore wind farms, even if the cables are only 10% of the costs of the offshore wind farm?
Gulski et al. have a very interesting paper in Renewable and Sustainable Energy Reviews (Elsevier) discussing the very hard problems of undersea cable technology and robustness.
The cost of cable failures could make them uninsurable, which would be the death of the offshore wind projects.
 

Koutsoyiannis et al. published a very important paper on the causality between CO2 and Temperature in MDPI, using a new stochastic analysis to find who is the cause and who the effect

. They conclude that "The results are clear: changes in CO2 concentration cannot be a cause of temperature changes". Wow!!! (see also guest post in Climate_etc. and this paper by Stuart A. Harris)

Judith Curry, Jim Johnstone and Mark Jelinek published an exhaustive analysis of the July 2023 global temperature. Their conclusions are sobering:
1.July 2023 global temp. anomaly is slightly lower than than of 2016, and comparable to that of 1998
2. There is an anomalous shortwave heating in the NH, which is influenced by the reduction in sulfate emissions from ship fuel (ships switched to cleaner fuel)
3. Any increase of the greenhouse effect from increasing CO2 is lost in the noise.
 

Data shows there's no climate catastrophe looming.

Watch this interview with Dr. John Christy, professor of Atmospheric Science at UAH.
Very sober, very clear!

Now that Vattenfall abandons its greatest offshore wind-project in the UK (see here), you may read this very interesting report on the costs of "renewable energy", and why contrary to the main-stream propaganda, the price of "renewable solar/wind electricity" steadily goes up and not down.

Aliens cause Global Warming

It's now over 20 years that Michael Crichton held his famous Michelin-Caltech lecture.

Please reread this presentation, that remains as important and true today as it was 20 years ago. His famous sentence

"There is no such thing as consensus science. If it’s consensus, it isn’t science. If it’s science, it isn’t consensus. Period"

should be the leitmotiv of every serious scientist, but alas, it isn't.

Read the entire text carefully, it will be time well spent!

M. Crichton a medical doctor, scientist, writer,  filmmaker, passed away in 2008. He remains famous for his books like Jurassic Park and State of Fear.

Dr. Roy Spencer has a very telling article in his blog on the difference between observations and models of the summer temperature trends in the US corn belt: the blue rectangle = observations of the 50 years trend, , the reds = prediction of 36 different CMIP6 models.

So would you built your climate policies on these "model foundations"?

Excellent paper by e.Venture (in German) on the future of the German decarbonized grid in 2040

"Wesentliche, erwartbare Erkenntnis ist, dass die Erzeugung aus Wind und PV der geforderten Nachfrage, bzw. Last nicht entspricht...Die Höhe des leistungsseitigen Defizits ist mit brutto 120 GW bei einer Maximallast von 146 GW erheblich. Anders ausgedrückt reicht an 5.000 Stunden im Jahr die Erzeugung aus Wind und PV nicht aus, die Bedarfe zu decken. "
 

The Holocene CO2 Dilemma

Renée Hannon has a new article on the Holocene (last 12000 years) CO2 and global temperature evolution, comparing observations (= temp.&CO2 derived from proxies) and models.

The difference is breathtaking: Global temp. from proxies are inverse proportional to CO2 levels (upper plot), whereas the models show the opposite (lower plot).... and all our curent climate policies are based on these models!

Hannon concludes: "The fact that CO2 correlates well to Holocene temperatures for only the Antarctic, or <10% of our planet's surface, yet CO2 is considered as the dominant influence on climate change is a scientific dilemma."

Read also the comments after the article, especially what XJavier Vinos writes:
So it turns out that the CO2 hypothesis and associated models can only explain 50 years of the past 11,700. And in doing so they render 11,650 years of climate change unexplainable. This is the mark of a failed theory. It would have been ditched long ago if it wasn’t for the strong political support. Many paleoclimatologists are very unhappy with it.

What causes Climate Change?

Read this short, but very clear comment by Daniel Nebert:
"The fact is: the more one looks into the intricacies of Earth’s extraordinarily complex climate system, the more apparent it is, how little we really know. Therefore, it’s best to proceed slowly and carefully — ignoring the subjective hype generated by mainstream media and politicians."

Nobelist (Physics, 2022) Dr. John Clauser says this:

“The popular narrative about climate change reflects a dangerous corruption of science that threatens the world’s economy and the well-being of billions of people. Misguided climate science has metastasized into massive shock-journalistic pseudoscience. In turn, the pseudoscience has become a scapegoat for a wide variety of other unrelated ills. It has been promoted and extended by similarly misguided business marketing agents, politicians, journalists, government agencies, and environmentalists. In my opinion, there is no real climate crisis. There is, however, a very real problem with providing a decent standard of living to the world’s large population and an associated energy crisis. The latter is being unnecessarily exacerbated by what, in my opinion, is incorrect climate science.”

OFF TARGET...Read this article by Prof. Lennart Bengtsson ( former at Max Planck Institute, University of Reading, European Center for Medium-Range Weather Forecasting...)

"There is nothing wrong with setting targets. However, it is important to first ensure that the objectives are reasonable and, above all, that they are feasible. Formulating irrelevant goals – or goals that cannot be achieved for scientific, technical or economic reasons – does not benefit anyone... The most sensible thing to do today is to study those areas of the world that have managed to adapt to harsh climates."

The 53th Earth Day is here, and not a single of the doomsday predictions by the "experts" and the media have been come true!

Never trust the prophets of doom!

The GWPF has published Prof. Ole HUMLUM's "State of the Climate 2022" report. Prof. Humlum analysis is based mainly on observations, and his conclusions are that even if land temepratures have increased since the 1970's, the total energy content of [atmosphere + ocean] seems to remain more or less stable, which would show that observed warming may result from a " redistribution of energy between ocean and atmosphere". Especially for variations of storms and hurricanes, "the continental US remains within the normal range since 1851"

New very complete paper in Nature Science Communications on "Spatial energy density of large-scale electricity generation..." by Noland et al. Biomass is worst, nuclear by far the best!and "... onshore wind farms are the second most dilute source for power generation"

Listen to the conference given by Prof. Steven Koonin in Paris the 23th March 2023 (in English, 56 minutes). Koonin is the former scientific and energy adviser of Barack Obama.
