Local trends 1998 to 2017


Location of meteoLCD

A new paper by W.T.Ball (ETHZ) and 21 (!) co-authors made big splashes in the media for its main finding that the total ozone column in the lower stratosphere is declining (contrary to what should be expected if the Montreal protocol was efficient).

As usual, journalists did not read the fine print...so look at my blog !


Prof. William Happer (Princeton University) has a short (5 minutes)and easy video at PragerU titled: "Can Climate Models Predict Climate Change?" You may guess the answer in advance!

There is a new paper by Thomas Frederikse et al. (Uni Delft) on sea-level changes along the US Northern West coast. One of the main conclusions is that possible human caused rise (through ice melt) is small compared to natural ground movements.

More on the blog.

Benoît Rittaud, president of the French "Association des Climato-Réalistes", mathematician at the Université Paris 13, was interviewed by the Luxembourg journal of finance AGEFI. Read here (in French) this crystal clear interview: "Les alarmistes du climat ont remarquablement réussi à se donner l’image de groupes désintéressés, de joyeuses bandes de hippies uniquement préoccupées du sort de la planète. En réalité, il est avant tout question de gros sous..."

A new paper by Yin et al. (Nature Communications) finds that climate models have big errors with the daily cloud cycle: they get the amplitude and the phase (= hour of maximum) wrong, which can lead to a radiative error up to 2.7 W/m2 to be compared to the 3.7 W/m2 radiative forcing assumed by the increase of atmospheric CO2 since pre-industrial times.

Wieviel Zappelstrom veträgt das Netz?

Watch the presentation by Prof. Hans-Werner SINN given at the LMU (Ludwig-Maximilian Universität München) on the German Energiewende (duration: 01:15).

"Wissen wir wirkich was wir tun? ...zumal wenn man bedenkt wie wenig zum Schluss bei dieser Sache herauskommt"

Read the paper on which  this presentation is based.

Short but very clear video from Jan Pieter Studt (German spoken, English subtitles) comparing the CO2 emissions of Germany to those of emerging developing nations (China and India). Make your own conclusion!

(h.t. EIKE)

With solar activity at a historic low, the dwindling solar wind is unable to chase away the cosmic rays reaching the earth. As a consequence, atmospheric (stratospheric) radioactivity is increasing since 2015! According to Svensmark's cosmic rays theory (and experiments), the result should be an increase in (lower) cloud cover and some cooling.(h.t. www.spaceweather.com)

Read the new Svensmark et al. paper in Nature Communications!

Fed up with climate scare? Global warming and COP23 blues? Read this gem of an essay (2005) of the great physicist Freeman Dyson: Heretical Thoughts about Science and Society: "As a scientist I do not have much faith in predictions".

You may also watch the same titled video of his presentation at Boston University.

Prof. Judith Curry has an interesting (provisional) slideshow on sea level that puts things back into perspective. She predicts 3 to 8 inch (about 7 to 20 cm) from 2017 to 2050, an insignificant number.
Just to show how silly the global sea level as a valuable metric is, look here for the sea level changes in Oslo (climate4you graph).
What's important is the local sea level change, not a modelized global level.

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 global probabilistic study of the Ocean Heat Content low-frequency variability: atmospheric forcing versus oceanic chaos. New paper by G. Sérazin et al. showing that "large-scale regional OHC trends computed on the 1980-2010 period cannot be unambiguously attributed to the atmospheric forcing in several oceanic basins at various depths". (link to summary, full version is paywalled).



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.
