Click on title to see the 1084 pages long list of the 22771 delegates at COP24. The relatively small African country of Guinea sends 406 delegates! Read comment (in German) here. Luxembourg dispatched 25 persons, see page 348. This makes 1 delegate per 30318 people for Guinea and 1 delegate per 24080 people for Luxembourg.

Extra-strong solar Coronal Mass Ejection triggers more than 4000 sea-mines during the Vietnam War (4 August 1972). Read this paper based on declassified Naval documents. (h.t. spaceweather.com):
"this storm deserves a scientific revisit as a grand challenge for the space weather community"

Another natural phenomenon to scare the people out of their minds: as we enter into a very deep solar minimum, the intensity of cosmic rays is increasing. Beware of planned flights, or of a career in the flying industry :-))
Read this well-written article from NASA's Spaceweather.

Just to confuse you definitively: read this paper on the relation-ship between death and Solar Activity (SA): lower SA will haste your journey to the Styx! (but curiously higher Cosmic Rays will make you live longer, go figure!)

This was the theme of a series of conferences organized by the University of PORTO in September 2018.

The $2.5 Trillion Reason We Can’t Rely on Batteries to Clean up the Grid

Very good article showing that using lithium-ion batteries for electricity storage in a 100% solar/wind/hydro fluctuating grid is impossible (electricity costs presumed to be 49 $/MWh for 50% renewables would go up to 1612 $/MWh for 100% renewables).

Read this good article on the 2018 economic nobelists Romer and Nordhaus. Nordhaus models give an optimum strategy with a CO2 tax starting at 30$/to, and accepting a warming between 2.5 and 4°C.

Read also this comment by Rémy Prud'homme with the conclusion "S’il présentait ses travaux à une réunion du GIEC, de l’IDDRI, ou d’un Climate Finance Summit, le Professeur Nordhaus serait accueilli à coup d’insultes et de tomates."

Global Warming for the two cultures.

The lecture given by emeritus Prof. Richard Lindzen (MIT) is a model of clarity: no avalanche of graphs, no incomprehensible statistics, no moral hype, no breathless "the end is nigh", just an extremely accessible text. Two citations will do:

"An implausible conjecture backed by false evidence and repeated incessantly has become politically correct 'knowledge'......What we will be leaving our grandchildren is not a planet damaged by industrial progress, but a record of unfathomable silliness."

An ode to nuclear waste

Read this wonderful article by the Dutch journalist Marco Visscher, published at spiked-online.
"Solar panels are nothing more than future electronic waste.... I do not want us to throw away our precious nuclear waste...Virtually every component of ‘nuclear waste’ has a useful application in industry, agriculture, science or medicine."

You may also read this comment of a former French nuclear engineer.

Science educators need to talk about the identity of scientists.

Read this well written article by Alan Levinovitz in the Washington Post about the scientific method, the fudging of data and morality in science research.

"At no point in my science education did I learn about fraudulent, biased or mistaken scientific conclusions...we should remember that what we want to believe — what’s easiest to believe — isn’t necessarily true."

Europe's renewable energy directive poised to harm global forests, and will even increase CO2 emissions!
"Wood that reaches a power plant can displace fossil fuel emissions but per kWh of electricity typically emits 1.5x the CO2 of coal and 3x the CO2 of natural gas"
One of the authors says that Treating wood as a carbon-neutral fuel is a simple policy decision with complex cascading effects on forest use, energy systems, wood trade and biodiversity worldwide. Clearly, many of these effects have not received due attention.”
Read also this article: Why burning trees for energy harms the climate.
and this article from Ireland: ‘Green’ home heating fuels causing ‘extreme levels of air pollution’
Click here for a picture showing that only 15% of the PM10's come from transportation, whereas wood burning contributes 27%.

Does Global Warming Drive Changes in Arctic Sea Ice?

Now that Arctic annual sea-ice minimum is higher than in many years a decade ago and Greenland ice sheet has for the 2nd year gained extraordinary more mass, chamjamal has an interesting blog paper showing that global temperatures increase is not statistically relied to Arctic sea-ice extent: "It is found that of the twelve calendar months only two contain both statistically significant sea ice loss and statistically significant correlation of the rate of sea ice loss with global warming...It is likely that the observed loss in sea ice area is a more complex phenomenon".


There is a new and interesting paper by Anne Harper (and 25 co-authors!) on the efficiency of bio-energy crops with carbon storage in the underground versus reforestation. The conclusion is that bio-energy crops (even with CCS) might well be a poor choice in CO2 avoidance and should be replaced by forest management. This long paper sits entirely on the outcomes of models and their vastly different conclusions....How miserable would the climatologist's life be if he had no models!
Title: Land-use emissions play a critical role in land-based mitigation for Paris climate targets.(Nature Communications).
How good are our CAIRSENS ground ozone measurements?Answer: they are very good!
Click on the left picture for an overplot of the measurements done by the Environmental Administration at Beckerich (dark-yellow curve) and ours at Diekirch (red curve) during the last 7 days of our heatwave.
Forget batteries, rare lithium, toxic ingredients etc. to store electrical energy: liquefy air with surplus electrical power and evaporate the air to drive turbines and generators to recoup (some of) the stored energy. The UK company Highview Power just made this happen, with a facility that uses mostly common components and easy to recycle steel. Is this the definitive solution for electricity storage?
Is the "battle for the climate" (bataille pour le climat) not compatible with democracy? Read this comment of Benoìt Rittaud (in French), English translation here): "...nous avons perdu toute capacité collective à mener un débat normal sur le climat."

An excellent paper on science, research and (mis)use of statistics: "Cargo-cult statistics and scientific crisis" by Prof. Stark (Berkeley) and Saltelli (Oberta). One of the best articles written on this subject for the last 10 years!
"cargo-cult statistics the ritualistic miming of statistics rather than conscientious practice. This has become the norm in many disciplines, reinforced and abetted by statistical education, statistical software, and editorial policies"
Read also this excellent paper by Carl Wunsch (from MIT):
"The perils of near-tabloid-science"


A new paper "The State of World's Beaches" by A. Luijendijk et al. on the changes of world beaches has been published by Nature's Scientific Reports. Globally there are more positive than negative changes since 1984. "Australia and Africa are the only continents for which net erosion (−0.20 m/yr and −0.07 m/yr respectively) is found, with all other continents showing net accretion." 
The authors also have set up a very clever Google Earth map which shows where beaches are increasing or eroding. Click on the left map and zoom up to see the bars corresponding to the detected trends.

A group of 33 geologists (current and former fellows of the GSL) wrote an open letter to its president contesting the GSL's position on climate change. One important argument is this one: "Why the 285 ppm of atmospheric CO2 estimated for the beginning of the Industrial Revolution is in any way, a desirable benchmark. It coincides with the Victorian Little Ice Age, a period of starvation and population decline, which cannot possibly be a desirable target, unless you want to depopulate the earth."
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.

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

"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.
