METALS for Clean Energy

Excellent report of KU Leuwen and Eurometaux on what will be needed in 2050 to reach Net Zero.

The necessary percentage increases are mind boggling!

Watch this presentation by Tom Gallagher "Lessons from Paleoclimatology...": a sober and easy to follow voyage into the past 66 millions of Earth's climate.
Some conclusions: "...in the Holocene there is nothing unusual about our current rate of warming...embrace the warmer, humid, CO2 fertilized times now..Prepare for more glaciation ahead!"

Read here a discussion in easy words from SEPP (original here)

The History of the LNT (Linear No Treshhold) theory of radioactive risk: watch this series of videos of the HPS debunking this almost 70 years old theory, which gathered momentum by fear, but also dishonesty and unscientific behavior. Dr. Calabrese is critical of LNT and says that hormesis is real for low dosis of radiation.
A report on the same subject (Reassessing Radiation Safety) is here.

Look also at www.radiationanswers.org for Q&A.


Prof. Ole HUMLUM latest analysis of the state of climate in 2021 is published. He looks not at what climate models predict, but what the observations tell us. He writes "...“A year ago, I warned that there was great risk in using computer modelling and immature science to make extraordinary claims. The empirical observations I have reviewed show very gentle warming and no evidence of a climate crisis.”
This 54 page report should be mandatory reading for everyone looking for a genuine and not biased discussion on what we know of the state of the global climate, of the changes of global temperatures, sea-level, ice-cover, hurricanes and other climate related phenomena.



Prof. Judith Curry (former Georgia Tech) has a very interesting article published in the March 2022 edition of "International Affairs Forum" Most contributors write in the usual alarmist or Zeitgeist manner, but Prof. Curry has "A Plan B for adressing climate change and the energy transition" (link to a version with  highlights by me; original version in her blog here): "...The dangers of manmade climate change have been confounded with natural weather and climate variability...The planet has been warming for more than a century.  So far, the world has done a decent job at adapting to this change.  The yields for many crops have doubled or even quadruped since 1960...To make progress on this, we need to disabuse ourselves of the hubris that we can control the Earth’s climate and prevent extreme weather events..."

Prof. Guus Berkhout (emeritus, Uni Delft) writes that "Experienced Engineers must take the lead in the Energy Transition" He stresses the importance of political decisions based on measurement data and not on theoretical models. Concerning climate action he asks:

  1. Is COreally the big culprit?

  2. Does massive wood burning really contribute to less global warming?

  3. Why does the output of ‘settled’ climate models not match real observations?

  4. Why do universities still go ahead with supporting green energy policies, while these policies will lead to severe poverty? Why did universities not make a plea for nuclear technology? Why was such a debate forbidden at COP26*?


Ruhnau and Qvist have published an interesting paper on the electrical storage requirements for Germany, assuming 100% renewable electricity production (no gas, no nuclear, state 2030). They find in their 35-years analysis that one should account for 12 weeks of energy scarcity in a year, and propose mostly hydrogen as a storage medium, with batteries playing a very small role; they ignore all the technical problems related to hydrogen storage, and probably under-estimate its cost. Including storage related losses, they find that during the 35 years there is one period where almost 3 month of storage would have been needed!
What makes one think again, is that they suggest vastly overbuilding wind and solar, and curtailing the excess power when needed. There is no reflection on the extra material consumption  for this excess capacity (which for instance needs 10 times more offshore wind than today!)

Read a critique of the R&Q paper here, and another discusssion here.

Blaming humans... largely a matter of faith!

Read this comment by Dr. Roy Spencer (UAH)... uncertainty about balance of outgoing/incoming radiation about 5-10 W/m2, to compare to presumed radiation forcing of human CO2 emissions of 1 W/m2.

"...most recent warming could be mostly natural.. and we would never know it"


R.C. Dickson
has written a very interesting 3 part essay "What every journalist and politician should know":

Part 1: The Scientific Process
Part 2: Numbers in Science
Part 3: Pathological Science

Read this, it is time well spent!

A very clear comment by Ian Aitken on the "97% consensus" saga that climate change is "predominantly" caused by human activity :  "Whilst there is almost total scientific consensus that climate change is ‘real’ and happening and that there has been some human-caused influence, there is no such scientific consensus over the extent of the human-caused influence and whether or not it could reasonably be described as ‘dangerous’, let alone a ‘crisis’."


Is the World ready for Good News on Climate? asks Roger Pielke (Uni. Boulder, Co.) in his discussion on his latest research, showing how many IPCC scenarios are possible and how many of its climate models get it wrong:

"...we have identified 71 of your 1,311 scenarios that reman plausible based only on what actually happened 2005 to 2020 and that number is cut in half, to 35, when we also consider the 2020 IEA projections to 2050." Link to paper here.

There is a new paper by Goode et al. published in Geophysical Research Letters on the Earthshine project, that since the late 1990's measures the Earth's albedo by the light reflected from the dark lunar portion: Earth's Albedo 1998-2017 as Measured from Earthshine.

The declining albedo is responsible for a radiative forcing of about 0.5 W/m2 during these 2 decades, similar to the 0.6 W/m2 attributed to increasing anthropogenic GHG emissions!

TRANSMUTEX is a new Swiss startup company that wants to solve the problem with existing nuclear waste with its TMX-Start reactor, and takes up an decade old idea of Prof. Carlo Rubbio: using a proton accelerator to produce an intense neutron beam that will convert Thorium and used nuclear waste into fissible U233, with only an absolute minimum of radioactive waste left. Read here!
Seeing how nuclear energy has many new starts is gratifying, and puts the silliness of countries allergic to nuclear power into perspective!



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.
