***live  CO2 emissions from electricty production***


Local trends 1998 to 2018


      Location of meteoLCD

Watch this TEDx (Danubia) presentation by environmentalist Michael Shellenberger:

 "Why renewables can't save the world"

(and why nuclear can!).

Many of us believe that an Hydrogen economy might be THE answer to a carbon-free energy world. Read his older but extremely clear report by Ulf Bossel (a fuel cell expert) and Baldur Eliasson (ABB) titled "Energy and the Hydrogen Economy".Did you know that for transporting the same energy amount as compressed H2 than as gasoline you will need 15 to 22  times more trucks? Read also this paper.

Click on the picture to look at one of the best illustrations of the urban heat island effect (UHI). Picture from NASA's Ecostress project shows how much warmer cities were during the morning hours of the June 2019 European heat wave.
Do you still have big confidence in thermometer readings located at airports or in cities?

More here.

Watch this very short but extremely clear presentation by Dr. Roy SPENCER (UHA) showing the discrepancies between climate models and observations (both by satellites and 4 reanalysis ). From the 102 CMIP5 models used by the IPCC only the Russian model comes close to the observations. Click here for the graph.
Wind turbines are big killers, and one of the causes of insect population loss! Read this comment in Forbes by M. Shellenberger: " a rough but conservative estimate of the impact of wind farms on flying insects in Germany is a loss of about 1.2 trillion insects of different species per year". Read the full text of the German report by Dr. Trieb here.
Shocking new research: trees are big emitters of the greenhouse gas methane! So you much criticised  cattle farmers, take solace that you are not the only climate wrong-doers anymore! (report from Yale University).

In these times where everybody aims to a net-zero carbon future, the excellent presentation of he late Sir David MacKAY "A reality check on renewables" is still an eye opener regarding the enormous land usage that biofuels and other renewables demand.

David MacKAY passed away in 2016; he was the Regius Professor of Engineering at the University of Cambridge (more here).

Concerning intermittent electricity storage in batteries, you may watch this interesting video "The Liquid Metal Battery: Innovation in Stationary Electricity Storage" by MIT Prof. Donald Sadoway. Listen what he says about the Lithium-Ion battery "a yeasterday solution".

Prof. Uberto Crescenti has prepared a call for reason titled "Pétition sur le le Réchauffement Climatique Anthropique" which has be signed until today by 91 professors, scientists and researchers.

Click here for the text in French, which has this sentence "La responsabilité anthropique du changement climatique observée au siècle dernier est donc exagérée de façon injustifiée et les prévisions catastrophiques sont irréalistes.... ". Original Italian text here.

Read this article (English translation) of Benny Peiser and Matt Ridley on the positive influence of higher atmospheric CO2 levels:
The unexpectedly slow rise in temperatures and the failure of predicted climate disasters to materialise has sparked growing concern among climate scientists...70 percent of global greening is due to the fertilisation effect of rising CO2 levels...the increase in CO2 emissions is beneficial for maintaining and potentially enhancing the recovery of rainfall in the Sahel region...”

(link to original article in German)

It is interesting to read an opinion from a far away and very important emerging country. Sanjeev Sabhlok (an economist) writes a comment titled "The warming effects of CO2 are benign" which holds the very interesting sentences: "The problem with climate “science”, however, is that the data – which are telling us to relax – fly in the face of the strong tendency of its advocates to bully us into a panic.....India should take it easy and focus on more important and urgent environmental issues. "
 During these hot days please remember that meteoLCD was and still is the only station of Luxembourg measuring and publishing the "official" heat-stress (WBGT) in near real time, starting in May 2001. This synthetic temperature is calculated from those measured by a dry, wet and globe thermometers, reflecting the incidence of direct solar irradiation (globe), evaporation (i.e. wind, wet bulb) and air temperature (dry bulb). Read here a recent paper on the WBGT and the article "Ambiance Chaude" by Dr. Charles Bonert and Francis Massen. Dr. Bonert was the head of the medical service of Luxembourg's army, and our installation in 2001 of the WBGT system was a joint venture between meteoLCD and this service.
Here a picture of our WBGT system (27Jun2019):

Here is a 800 pages blockbuster report by the NIPCC on the economics of using or not using fossil fuels. "...the authors...find that while climate change is occurring and a human impact on climate is likely, there is no consensus on the size of that impact relative to natural variability, the net benefits or costs of the impacts of climate change."
More than 100 scientists were involved in the making of this report by the NonGovernmental International Panel on Climate Change.

Watch this excellent presentation by Laurent ALEXANDRE (in French) given at a conference of the "climato-réalistes", where he talks about climate religion, "collabsology" and exponential hysterical political decisions: "le discours religieux collabsologique prévoyant la fin du monde s'est développé à une vitesse absolument sidérante".

Laurent Alexandre is a medical doctor (in chirurgical urology) and entrepreneur; he writes regularly in the "l'EXPRESS".

Climate's Uncertainty Principle

Read this very clear written article by atmospheric physicist G. Paltridge, published in Quadrant Online: "...reasonably correct forecasts of the average climate of the world might be possible in principle. On the scale of regions (anything much smaller than the scale of the major ocean basins for example) it has yet to be shown that useful long-term climate forecasting is possible even in principle."

Non uniform contribution of internal variability to recent Arctic sea ice loss by Marc England et al. (Columbia University, New York,  University of Colorado at Boulder): "...nearly half of the observed loss of summer sea ice cover is not due to anthropogenic forcing, but due to internal variability...spring (April-May) sea ice loss, notably in the Barents Sea, has so far been dominated by internal variability."
Paper published by AMS.


A new 200 year spatial recontruction of West Antarctica surface masse balance.
New paper by Yetang Wang et al. (JGR Atmospheres) which concludes that
"significant negative trend (-1.9 ± 2.2 Gt yr-1 decade-1) in the SMB over the entire WAIS during the 19th century, but a statistically significant positive trend of 5.4 ± 2.9 Gt yr-1 decade-1 between 1900 and 2010".
So during a period of strongly increasing atmospheric CO2 levels the SMB of the WAIS increased!
(WAIS = West Antarctica Ice Surface , SMB = Surface Mass Balance)
Kohlemotoren, Windmotoren und Dieselmotoren: Was zeigt die CO2-Bilanz?

Read this extraordinary clear and easy to read paper by Christoph Buchal, Hans-Dieter Karl and Hans-Werner Sinn: E-cars emit more CO2 per km as modern Diesel cars, if you make a serious calculation and do not accept the politically correct monster-lie. The authors propose to introduce hydrogen as the best storage medium for excess green electricity, and convert it to methane to power the cars (or to use fuel cells to power E-cars): "Wir vermuten in der postulierten vollständigen Emissionsfreiheit der E-Autos eine industriepolitische Täuschung..."
See comment on the blog.


The State of the Climate 2018

Read the latest report by Prof. Ole Humlum (Uni. Oslo, Uni.Center Svalbard, creator of the climate4you website) with clear data and no hype.

From the summary: "Since 2004, when the Argo floats came into operation, the global oceans above 1900m depth have on average warmed somewhat. The maximum warming (between the surface and 120m depth) mainly affects oceans near the equator, where the incoming solar radiation is at a maximum. In contrast, net cooling has been pronounced for the North Atlantic since 2004."


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***!


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

"The greatest challenge facing mankind is the challenge of distinguishing reality from fantasy, truth from propaganda."

"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.
