Outstanding article by Thea Dorn in the German ZEIT online "Nicht predigen sollt ihr, sondern forschen!"
"...Wissenschaftler haben durch Zweifel zu glänzen, nicht durch Rechthaberei...Eine der tragischsten Taten, die eine Demokratie begehen kann, ist Selbstunterwerfung unter die rigiden Handlungsvorschriften einer klerikal auftretenden Naturwissenschaft aus Angst vor dem Unterworfensein unter die Macht der Natur..."

Impact des EnR: Watch this very interesting video of the presentation of Marc Jancovici on the impact of renewable energy in France (French spoken). I do not agree with Jancovici on his appreciation of climate urgency, but as an engineer he has very clear and solid arguments concerning intermittent renewables and nuclear energy.
Especially interesting is his graph showing that  the price of "renewable" electricity risks becoming negative above a certain percentage of produced wind-power w.r. to the installed capacity (a more and more frequent situation in Germany, for instance).


Open letter to the KNAW (Royal Netherlands Academy of Arts and Sciences) by Prof. Guus Berkhout, founder of CLINTEL (Climate Intelligence Foundation), asking for not excluding scientists with alternative views.
" What concerns me about this embarrassing state of affairs is that science is being misused to provide spurious justification for wishful climate policy and that the scientific establishment is looking the other way...The IPCC was supposed to be a scientific initiative – I was a strong supporter of it myself. However, it has emerged as a political organisation that abuses science."

"On Behalf of Environmentalists I apologize for the Climate Scare"

writes well known environmentalist and climate activist Michael Shellenberger. In his list of what to do note this:

- 100% renewables would require increasing the land use for energy from today's 0.5% to 50%
- the most important thing for reducing air pollution and carbon emissions is moving from wood to coal to petroleum to natural gas to uranium


Prof. Richard Lindzen has published a very interesting paper "An oversimplified picture of the climate behavior based on a single process can lead to distorted conclusions".

New study by Ulrich Schmidt (Kiel Policy Brief 143, Jun. 2020, Institut für Weltwirtschaft) on E-cars:

"...führen zu 73% höheren Treibhausgasmissionen als moderne Diesel-PKW"





The Frost Saints or Ice Saints days ("Eisheiligentage") are cooling since 1998 at meteoLCD, and still longer in Germany. Did you hear about that in the media? More on the blog.


Research done at a geothermal power station in Iceland has shown that gazeous CO2 dissolved in water which is injected into underground basalt rocks mineralizes in just 2 years, and such will be safely stored away indefinitely without any risk of leakage as they may exist in traditional CCS (Carbon Capture and Storage) systems..

The ongoing solar minimum continues to increase the cosmic radiation at the altitudes of transatlantic flights (20000 - 40000 feet). The hourly dose may reach about 3800nSv, to be compared to the 80nSv common at ground level (look at our radioactive measurements!)

Read this interesting article on HALEU (high-assay, low enriched) nuclear fuel from disused ERBII reactor and its planned use in the Oklo Aurora micro-reactor at INL (Idaho National Laboratory). HALEU is seen by many as the fuel for small reactors and as a tool to recup energy from spent nuclear fuel.

The Oklo Aurora reactor is a reactor running on metallic fuel, without any liquid circuits.

The German philosoph Gunnar KAISER asks 12 very logical, but easy to understand questions regarding climate and its variation; he asks these questions to the famous TV physics professor Harald Lesch. Watch the YouTube video (German spoken, about 17 minutes) and just try to follow the logic!

Look at these graphs which show a similar 60-year sinus-pattern for the velocity of warming and the change in ocean heat content. Note also that the velocity of warming seems to be uncorrelated to the yearly CO2 emissions (here gigaton C/year, right axis, red plot).

Clive BEST has a good article on the baseline problem of temperature series, and why the choice of the baseline period is influencing the concordance (or discordance) between models and observational data: "It is the model projections which change dramatically when using different baselines. One should always bear this in mind whenever  an ensemble of models seem to perfectly  match the data well."

Why Greta Thunberg should go back to school

Read this essay by Alessandro van den Berg, an economics teacher from the Netherlands and also a person with autism. (7 Jan 2020).
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.

The data of MeteoLCD are used to compute the UV-Index published by several Luxembourg periodicals. A research project done in collaboration with the Radiation Protection Office of Luxembourg studies the general UV pattern and the relationship between UVB irradiance and tropospheric ozone concentrations.
