Please take a step back, and stay cool for a moment. Shut your ears off from the deafening cries and shouts of the global warming advocates, and sharpen your mind. Try to answer the questions outlined in the papers given hereafter, and be open for good reasoning: these pages might make you think again, and wonder, if the mobiles of all these climate catastrophers are pure ....
Working for clean air
and an unpolluted atmosphere is a laudable aim, but forgetting
to compare the magnitude of man-made pollutants to the natural
sources, or having an absolute faith in measurement data of
often dubious origin, is unscientific at least, and foolish
certainly. The climate is "the changing state of the
atmosphere", so do not expect a steady state situation. Do not
forget either that the sun is the engine which drives
everything, and that the output of that engine is in constant

|Climate Change - a different Perspective||Here is a transcript (PDF, highlighting by me) of two discussions between Prof. Judith Curry and Christopher Balkaran of "The Strong and Free Popdcast" titled "Climate Change - a different Perspective". Curry's answer are absolutely no frills, sincere and intelligent.. The transcript is easy to read, and you will not regret the time spent!|
|Lecture by Prof. William Happer||Watch this lecture by Princeton professor William HAPPER given in Amsterdam at Clintel the 15th Nov. 2021. Especially interesting is his point on the levels and importance of CO2 and CH4 atmospheric concentrations.|
|Read this essay by ecologist Michael Shellenberger : "...No global problem has ever been more exaggerated than climate change... the people who claim to be most alarmed about climate change are the ones blocking its only viable solutions, natural gas and nuclear.. .as a religion, climate change has a fraudulent aspect"|
Read this new article by Prof. Richard LINDZEN
"Despite the fact that increases of CO2 thus far have been accompanied by the greatest increase in human welfare in history, and despite the fact that there have been large increases in the Earth’s vegetated area largely due to increases in CO2’s role in photosynthesis, governments seem to have concluded that another 0.5 C will spell doom...climate hysteria in the West leads to policies that clearly benefit China...the need for an open debate over both our assessment of climate science and the proposed policies is, indeed, desperately needed"
|Video by Jean Pütz||
Watch this short video on Facebook by Jean Pütz, our most famous Luxembourg former TV presenter of technical things. He talks about the previsible GAU ("Grösster Anzunehmender Unfall") that the Energiewende risks to bring to the German Electricity Net. (8 minutes, German spoken).

Researchers at the MIT fusion center
MIT-CFS have developed a
20 Tesla superconducting magnet, which
allows to build a classical tokamak fusion reactor
40 times smaller. Their SPARC prototype is expected
to start at 2025 and to be the first fusion device
delivering more energy than it needs to operate

|How much has the Sun influenced Northern Hemisphere temperature trends? An ongoing debate.||
New and very important paper by Connolly et al. in Research in Astronomy and Astrophysics (April 2021). Read short discussion in the blog.
|AR6: GHG attribution faulty since over 20 years!||
Prof. Ross McKitrick shows that the IPCC relies since more than 20 years on a statistically flawed paper when attributing global warming to GHG's (AR6 says "unequivocal")
|The Problem with Climate Change Politics||
Read this excellent article by Alasdair McLeod :
"But it is not widely appreciated that the process of hyping up climate change into a full-blown crisis has become the consequence of a crowd psychology rather than a pursuit of the facts."
Here it is again! The AR6 SPM reintroduces the ignominuous hockeystick, and cancels the Roman and Medieval Warm Periods.
Read this damning critique of Steve McIntyre on this woke SPM ! "...one surely presumes that IPCC climate scientists, who are employed full time on these topics, to be competent enough to notice things that I was able to observe in my first day or so of looking at PAGES2019. But their obtuseness never ceases to amaze. "
|How Climate Scenarios lost Touch with Reality||Excellent article by Prof. Pielke Jr. & Ritchie in ISSUES in Science and Technology (no.4, 2021): "...Implausible climate scenarios are also introducing errors and bias in actual policy and business decisions."|
Excellent paper by Murphy & McKitrick showing
that the cost of "climate" policies to limit global
warming to 1.5°C costs more than doing nothing!
Very easy and extremely clear written paper, should be a must for every economist! No frightening maths, just crystal-clear logic.
|The Peril of Politicizing Science||
A marvellous, really must-read essay by Anna Krylov (Uni. Southern California, LA) published in the Journal of Physical Chemistry (10 June 2021)
Teachers: let your students read this!
|Decline of wind and solar electricity with increasing penetration.||
New important paper by Millstein et al. on the decline of wind and solar electricity value with increasing penetration. This is a 28 pages paper, well worth to read twice! Above 20% of wind/solar penetration, the produced electriccity value falls by 30 to 40%. See BLOG !
Climate change uncertainty in 5 minutes !
|Safety of Grid Scale Lithium-ion Battery Energy Storage Systems||
Planning for big battery storage systems for your intermittent solar and wind electricity? Beware of the huge fire risk, and read this June 2021 paper by 3 British university physics professors: "Safety of Grid Scale Lithium-ion Battery Energy Storage Systems". They write "the explosion potential and lack of engineering standards to prevent thermal runaway may put control of battery fires beyond control, experience and capabilities of local Fire and Rescue Services"
Another older comment here.
|Revised estimate of ocean-atmosphere CO2 flux||
The oceans absorb much more CO2 than assumed! Read this paper (Sep.2020, Nature Communications) by Watson et al. with the conclusion that "...most ocean models underestimate uptake... Some revision of the global carbon budget is required".
Supplementary information here.
TerraPower ( a Bill Gates company)
and GE Hitachi Nuclear Energy will build a fast
neutron reactor called "NATRIUM"
(as it is cooled by liquid sodium): this is a rather
small 345 MWe breeder, with a huge molten salt
thermal storage which can boost power up to 500 MWe. The reactor will be built in Wyoming, probably
on the site of a former coal power station.
It's interesting that a Republican state is absolutely in-line with Democrat President Biden, concerning USA's energy future. What a difference with "old Europe"!
|The State of Climate 2020||
Read this latest report by Prof. Ole Humlum; this is a report based on observations, not models! Just one sentence of this outstanding report:
"Since 1979, lower troposphere temperatures have increased over both land and oceans, but most clearly over land areas. The most straightforward explanation for this phenomenon is that much of the warming is caused by solar insolation, but there may well be several supplementary reasons, such as changes in cloud cover and land use."
|The Invisible Killer||As a longtime asthma sufferer I appreciate clean air; our PM Airvisual measurements contribute a bit to give us real data. But environmental questions very often have an agenda, greatly helped by poor or fraudulent statistics. Read this paper on how bad the situation is in relating heart attacks to PM 2.5 concentration. Full paper here, easier to read discussion by the authors here.|
|Climate Policy - When Emotion Meets Reality||
Watch this very sober, clear and
non emotional presentation by Prof. Ross Mc Kitrick
(Guelph University), 12 May 2021.
"...emissions mix globally... so unilateral action is useless...policies that were too small to have an effect turned out to be too costly to implement...increasing the scale of policies pushes the costs up faster than the benefits..."
|Undue Climate Haste||
New large 30 pages report by Marcel Crok from CLINTEL.
Conclusion: "In any case, the message of this essay was that we are in no hurry and that panic is unwarranted. Climate change always deserves our attention, but the idea that we need to turn our energy supply upside down right now seems mainly an emotional decision."
"This redefinition of ‘climate change’ to refer only to manmade climate change has effectively eliminated natural climate change from the public discussion on climate change....Climate change has thus become a grand narrative in which human-caused climate change has become a dominant cause of societal problems...This grand narrative misleads us to think that if we solve the problem of manmade climate change, then these other problems would also be solved"

|Heat storage for the house||
Mathias SCHMIDT and Marc LINDER have written an
intersecting paper in Frontiers in Energy Research (link)
how to use excess PV electricity in summer to get
heat storage for the house during the winter.
They use the exothermic reaction of calcium oxide
--> calcium hydroxide, and find that an overall
storage efficiency of nearly 96% would be possible,
with a manageable volume of this low-cost material.
The 12 pages paper is relatively easy to read!
|Climate Emergency... not so fast!||
Excellent, very clear and sober article by two world-renowned physicists : Richard Lindzen, MIT, and William Happer, Princeton. A French translation is here.
Read also this article of Dr. Roy Spencer: An Earth Day Reminder: "Global Warming" is Only ~50% of What Models Predict.
Excerpt: "Yes, more CO2 must produce some warming. But the amount of warming makes all the difference to global energy policies. Seldom is the public ever informed of these glaring discrepancies between basic science and what politicians and pop-scientists tell us."

Read this excellent policy brief by Prof. Vaclav Smil (Uni. of Manitoba) and reflect on this sentence, that says it all:

|Die Energiewende ist gescheitert||
Read this caustic article (in German) by Dr. Björn Peters (a physicist) at the Umwelt-Watchblog. "Die Energiewende ist also an ihren eigenen Zielsetzungen und ihrer eigenen Metrik gescheitert, nicht auf Basis der Verleumdungen ihrer Gegner".
About 800 scientists have written a
letter to Biden, von der Leyen and al., asking
them to stop using forests as biomass (wrongly
considered carbon neutral in the EU). Among the signaturies is Jean-Pascal van Ipersele from Uni.
Louvain, , former IPCC vice-president!

|Adaptation much more profitable than mitigation||
Clintel has a new Press Release titled "adaptation much more profitable than mitigation".
They write that "one dollar invested in adaptation yields about 4 dollar in benefits" whereas (according to B. Lomborg) "one dollar spent for mitigation leads only to 11 cent benefit".
Especially telling is the graph (click for full scale) which shows that the deaths from climate related catastrophic events decreased spectacularly since 1920, whereas the non-climate catastrophe death toll remains more or less constant.
|Nicola Scafetta (Uni. Naples) published a very interesting open-access paper on the contamination of land-temperature measurements by the UHI (Urban Heat Island) effect (Springer, Climate Dynamics). Click here for the full paper. He concludes that the ubiquitous CMIP5 climate models may overestimate global warming since 1940 by up to 40% !|

|Dependence of Earth’s Thermal Radiation on Five Most Abundant Greenhouse Gases,||
W.A.Wijngaarden (York Uni., Canada) and W. Happer (Princeton Uni.,USA) have published a remarkable paper on the influence of doubling the actual concentrations of greenhouse gases (GHG). The paper is very math-heavy and not easy to read, but 2 conclusions are important:
1. at current concentrations the forcings from all GHG are saturated, so...
|James Randi||James Randi, the master of the skeptical scientists and magician extraordinaire passed away 92 years old. Read the New York times obituary of this outstanding debunker of scientific and paranormal fraud, and read here what he had to say on climate change.|
A new paper by Margaritelli et al. published in Nature - Science Reports (link) shows that the Mediterranean surface water temperature were during the Roman Warm Period about 2°C warmer than today! CO2 levels are assumed < 280 ppm at these times, which should make you think again. The authors conclude that during the Roman Optimum " ... developed the greatest ancient civilization of all time, the Roman one. We hypothesise the relevance that these climate conditions may had in the expansion of the Roman Empire and its collapse with the general development of colder conditions." (the original figure left has been edited by me by adding text and arrows).
Tell this the climate alarmists of today!
|Meridional Distributions of Historical Zonal Averages and Their Use to Quantify the Global and Spheroidal Mean Near-Surface Temperature of the Terrestrial Atmosphere||
A very important new paper by Kramm et al.
shows how historic papers from 1850 to 1910 evaluate
zonal yearly average temperatures, and how they
differ to the "consensus" values.
|Temperature and mineral dust variability recorded in two low-accumulation Alpine ice cores over the last millenium||A very interesting paper by Bohleber et al. published in "Climate of the Past". From 2 ice core drillings done at the Colle Gnifetti (Monte Rosa) they deduce from the observed dust layers a temperature profile going back to 800 AD. And surely, the MWP (Medieval Warm Period) and the LIA (Little Ice Age) are there, all periods which have been belittled in the TAR of the IPCC (because old warming periods not caused by CO2 do not fit into the narrative!).

|Nicht predigen sollt ihr, sondern forschen!||
Outstanding article by Thea Dorn in the German ZEIT
"...Wissenschaftler haben durch Zweifel zu glänzen, nicht durch Rechthaberei...Eine der tragischsten Taten, die eine Demokratie begehen kann, ist Selbstunterwerfung unter die rigiden Handlungsvorschriften einer klerikal auftretenden Naturwissenschaft aus Angst vor dem Unterworfensein unter die Macht der Natur..."
|Impact des EnR||
Watch this very interesting video of
the presentation of Marc Jancovici on the impact of
renewable energy in France (French spoken). I do not
agree with Jancovici on his appreciation of climate
urgency, but as an engineer he has very clear and
solid arguments concerning intermittent renewables
and nuclear energy.
Especially interesting is his graph showing that the price of "renewable" electricity risks becoming negative above a certain percentage of produced wind-power w.r. to the installed capacity (a more and more frequent situation in Germany, for instance).

|Injected CO2 mineralizes in just 2 years||
Research done at a geothermal power station in Iceland has shown that gazeous CO2 dissolved in water which is injected into underground basalt rocks mineralizes in just 2 years, and such will be safely stored away indefinitely without any risk of leakage as they may exist in traditional CCS (Carbon Capture and Storage) systems..
|Ongoing increase in cosmic radiation||
The ongoing solar minimum continues to increase the cosmic radiation at the altitudes of transatlantic flights (20000 - 40000 feet). The hourly dose may reach about 3800nSv, to be compared to the 80nSv common at ground level (look at our radioactive measurements!)
|Similar sinus pattern of the velocity of warming and the change in ocean heat content||
Look at these graphs which show a similar 60-year sinus-pattern for the velocity of warming and the change in ocean heat content. Note also that the velocity of warming seems to be uncorrelated to the yearly CO2 emissions (here gigaton C/year, right axis, red plot).
|12 very logical questions||
The German philosoph Gunnar KAISER asks 12 very logical, but easy to understand questions regarding climate and its variation; he asks these questions to the famous TV physics professor Harald Lesch. Watch the YouTube video (German spoken, about 17 minutes) and just try to follow the logic! h.t. Die Kalte Sonne
Read this interesting article on HALEU (high-assay, low enriched) nuclear fuel from disused ERBII reactor and its planned use in the Oklo Aurora micro-reactor at INL (Idaho National Laboratory). HALEU is seen by many as the fuel for small reactors and as a tool to recup energy from spent nuclear fuel.
The Oklo Aurora reactor is a reactor running on metallic fuel, without any liquid circuits.
|The baseline problem of temperature series||Clive BEST has a good article on the baseline problem of temperature series, and why the choice of the baseline period is influencing the concordance (or discordance) between models and observational data: "It is the model projections which change dramatically when using different baselines. One should always bear this in mind whenever an ensemble of models seem to perfectly match the data well."|

|There is no Climate Emergency||
800 scientists wrote a letter to the UN Secretary-General with the message that there is no climate emergency.They write that "warming is far slower as predicted", that "climate policy must respect scientific and economic realities" and that "our advice to political leaders is that science should strive for a significantly better understanding of the climate system, while politics should focus on minimizing potential climate damage by prioritizing adaption strategies based on proven and affordable technologies"
|Steven DeWitte et al. (RMI and Uni. Brussels)have published a very interesting paper on the changes of the imbalance of the Earth's radiative budget during the period 2010-2018. Despite an increasing concentration of atmospheric greenhouse gases this imbalance has not increased (as one would expect) but ***decreased***, in correlation with the changes in the heat content of the oceans. They also find that the influence of changes in global sea ice to the amount of reflected solar radiation is small.|
|We’ve just had the best decade in human history. Seriously.||
For the coming days of joy and appeasement,
read this optimistic comment of Dr. Matt Ridley in
"A modern irony is that many green policies
advocated now would actually reverse the trend
towards using less stuff....Environmental opposition
to nuclear power has hindered the generating system
that needs the least land, least fuel and least
steel or concrete per megawatt...Technology has put
us on a path to a cleaner, greener planet. We don’t
need to veer off in a new direction. If we do, we
risk retarding progress.".

|The Toxic Rhetoric of Climate Change||
Excellent text by Prof. Judith Curry from
Climate etc. (14-Dec_2019):
" ...Over the past century, there has been a 99% decline in the death toll from natural disasters, during the same period that the global population quadrupled....
... We still don’t have a realistic assessment of how a warmer climate will impact us and whether it is ‘dangerous.’ ...
... We have not only oversimplified the problem of climate change, but we have also oversimplified its ‘solution’".
|Has global warming already arrived?||
An interesting paper by Varotsos and
Efstathiou (Climate Research Group, Uni Athens)
published in the Journal of Atmospheric and
authors analyze satellite data and find that the
observed temperature field in the global troposphere
and lower stratosphere is different from what global
warming theory says. They conclude that
"...it is not possible to reliably support the view of the presence of global warming in the sense of an enhanced greenhouse effect due to human activities".
|Capacity factors for wind and solar in the UK (2002-2018)||
Here are the capacity

practically constant at an appalling low figure of
10% (to be compared to nuclear or gas at ~90%).

|International Energy Outlook 2019||
... published by the EIA (US Energy Information
Consumption of petroleum and other liquid fuels is expected to rise in 2050 from actual 50 to about 80 million barrels/day in non-OECD countries, and remain more or less stable at 45 in OECD countries; so total world consumption would be about 130 million barrels/day in 2050 (about 100 in 2018).
|Observational data from tide-gauges||
Even if some alarmist (German) climatists speak of accelerating global sea-level rise, this is not so. Read this comment and this report from Prof. Judith Curry. Click here for observational data from tide-gauges (Prof. Ole Humlum's climate4you web site) for many locations. The level measured by tide-gauges (relative sea-level) is what counts for eventual adaptation measures!German (Wismar) and Dutch (Den Helder) tide gauges show an unspectacular linear trend of about 1.41 mm/y since 1860 (i.e. the end of the Little Ice Age cooling).
|Interruption of two decades of Jakobshavn Isbrae acceleration and thinning as regional ocean cools||
In these times where media news of Arctic and NH
glacier meltdown might drive you into depression,
recover to sanity by reading this paper by Khazendar
et al, published by Nature GeoScience (paywalled,
full version easy to find). This glacier is the
biggest contributor to Greenland ice loss. Since
2016 its retreat and thinning has stopped: it is now
thickening and advancing!
The cause is the well-documented North Atlantic cooling, itself probably influenced by the AMO (Atlantic Multidecadal Oscillation).
|Propagation of Error and the Reliability of Temperature Projections||
This paper by Dr. Patrick Frank (SLAC, Princeton University) did much furore and lead to many lively discussions, also among climate realists. Applying standard text-book error/uncertainty calculations, he shows that the temperature projections by the climate models can not be trusted, as the small predicted increase is buried in a huge uncertainty (because these models ignore/do not properly account for cloud forcing uncertainty).
