Local trends 1998 to 2022   


    Location of  meteoLCD

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.”

Click here for the video of his exposé.


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"

Read a math-free, easy to follow discussion here!

Attention: on the left-side figure the Y-scale is logarithmic!

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.

His latest book is "Unsettled, what climate science tells us, what it doesn't"

Multi-part comment in the BLOG on the problem of air quality and the different and often confusing multitude of defining the air quality index.

Read here parts 1, 2, 3, 4 and the last part 5.

Excellent and very short video from Prager online University with Prof. Richard Lindzen from MIT who tells the essentials in crystal clear words .

An absolute ***must view***!



1. A look at the Shape of Temperature Change over Time. Interesting blog comment at WUWT by Mark Fife concluding "In every 10-year average, 99.7% of the stations fall within 2.25° and -1.75° of their 1920 – 2011 average".

10. A real cool 12 minute video by Dr. David Evans "Climate change in 12 minutes". Peek also into this animated video by Dr. Roy Spencer.


Bill Gates, who said poor countries “desperately need cheap sources of energy now to fuel economic growth that lifts families out of poverty. They can’t afford today’s expensive clean energy solutions and we can’t expect them to wait for the technology to get cheaper.” - See more at: http://www.thegwpf.com/new-climate-change-battlefront-pits-tony-abbott-against-the-anti-coal-brigade/#sthash.J5szcsdQ.dpuf

James Lovelock: "They all talk, they pass laws, they do things, as if they knew what was happening. I don’t think anybody really knows what’s happening. They just guess. And a whole group of them meet together and encourage each other’s guesses." (link)

97. Words of the great physicist Freeman Dyson: "Unfortunately the global warming hysteria, as I see it, is driven by politics more than by science. If it happens that I am wrong and the climate experts are right, it is still true that the remedies are far worse than the disease that they claim to cure."

98. Words by the great French philosopher Pascal Bruckner: "All the foolishness of Bolshevism, Maoism, and Trotskyism are somehow reformulated exponentially in the name of saving the planet.
" (comments here and here)

99. R. Lindzen: "Future generations will wonder in bemused amazement that the early 21st century's developed world went into hysterical panic over a globally averaged temperature increase of a few tenths of a degree and, on the basis of gross exaggerations of highly uncertain computer projections combined into implausible chains of inference, proceeded to contemplate a roll-back of the industrial age"

 "Le doute est le commen-cement de la science ; qui ne doute de rien n'examine rien ; qui n'examine rien ne découvre rien ; qui ne découvre rien est aveugle et demeure aveugle".
Jean Chardin, 1686. Journal du voyage du chevalier Chardin en Perse.


Some say the world will end in fire,
Some say in ice.
From what I've tasted of desire
I hold with those who favor fire.
But if it had to perish twice,
I think I know enough of hate
To say that for destruction ice
Is also great
And would suffice.
Fire and Ice, R. Frost, 1920

"Und denn, man muß das Wahre immer wiederholen, weil auch der Irrtum um uns her immer wieder gepredigt wird, und zwar nicht von einzelnen, sondern von der Masse. In Zeitungen und Enzyklopädien, auf Schulen und Universitäten, überall ist der Irrtum oben auf, und es ist ihm wohl und behaglich, im Gefühl der Majorität, die auf seiner Seite ist". Johann Wolfgang von Goethe, 1828.
