Local trends 1998 to 2013 Location of meteoLCD

The 16th September is the International Day for the Preservation of the Ozone Layer!


This 16th September is meant to commemorate the 1987 Montreal protocol banning human made ozone depleting gases, like chlorofluorocarbons. Read here a longer explanation of the chemical reactions which reflects the traditional view.
This NASA graph shows that a few years after Montreal, the yearly minimum of ozone layer thickness at the South Pole stabilized (but did not markedly recover!). The scientific reasons for the ban, which seemed complete and rock-solid at that time, are becoming gradually more uncertain, as more natural sources of ozone destroying gases were found (e.g. bromides emitted by plankton) and a new mecanism in the South Seas has been detected. Also unexpectedly new gases have been found recently that seem to destroy ozone.
Caring for the ozone layer is noble, but as often in environmental problems much hype and hysteria muddled the problem; above all, the science really is not settled!
MeteoLCD measures the thickness of the ozone layer above Luxembourg since 1998, and the linear trend does not show an ongoing thinning; neither are the UVB irradation levels increasing (look at the trends page). Look also here for the results of the Uccle station, which is one of the longest acting measuring stations in the world.

1. data show no continuing further thinning of the ozone layer.
2. the natural occuring ozone hole above Antarctica has stabilized.
3. in our regions, the trend is more on an increase of the layer. The UVB irradiation at ground level is not increasing.
4. In our region the thickness of the ozone layer often varies tremendously on extremely short periods. To expect a constant thickness of the ozone layer is foolish.

PS1: you may read Matt Ridley's comment in The Times :The Ozone Hole Isn’t Fixed. But That’s No Worry (go to chapter 6 here)

PS2: here is the report of the EEA on the European emissions of ozone depleting substances

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.

Cours de Formation pour Exploitants de Solariums- Lehrgang für Solarienbetreiber (2008)

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.
