The Global Warming Sceptic  (2017-2018)
version 2.2  14 Feb 2009

This page does not represent an official position of the Lycée Classique de Diekirch or the Ministry of Education on climate change and global warming. The official position of the Ministry of Environment of Luxembourg can be found here. If you do not want to read the following links and discussions, please go back!

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 change!

"Quotes"  Hockey-Stick discussions

last update:07 Dec 2017

Climate Change: The Rule in the Geological Record With COP23 coming to steam, it would be a good idea to re-read the presentation by Prof. Alain Préat (ULB): "If one thing has been constant about Earth's climate over geological time, it is constant change."
Did European temperatures in 1540 exceed present days records?  ... asks René Orth and co-authors from ETHZ, Uni. Giessen and Uni. Bern in a paper published in IOP (open access). The answer is probably yes (medium confidence in IPCC speak)!  "Our results show medium confidence that summer mean temperatures(TJJA) and maximum temperatures(TXx) in Central Europe in 1540 were warmer than the respective present-day mean summer temperatures (assessed between 1966–2015)".
(h.t. GWPF)
Recent increases in terrestrial carbon uptake at little cost to the water cycle Higher atmospheric CO2 levels increase global plant productivity and water usage efficiency, according to Cheng et al. in Nature Communications (July 2017, link to pdf)

Daring to Doubt Tony Abbott, former Australian prime minister, gave on the 9th October 2017 a lecture at the GWPF in London.
You might not agree with every statement made, but reflect on these two sentences:
Beware the pronouncement, “the science is settled”. It’s the spirit of the Inquisition, the thought-police down the ages."
2. "A market that’s driven by subsidies rather than by economics always fails. Subsidy begets subsidy until the system collapses into absurdity."

Are Climate Models Overstating Warming? Ross McKitrick (University of Guelph) has a comment on Climate Etc. : "The model-observational discrepancy is real, and needs to be taken into account especially when using models for policy guidance."

Read also here, here and here and this comment from Michel de Rougemont: "To date, no instrumental observations made in our climate system can disentangle anthropogenic effects and natural variations."

The Little Boy

New important publication by Prof. A. Tsonis (atmospheric science, University of Wisconsin-Milwaukee) on ENSO (El Nino Southern Oscillation) and its relation to climate change: "...the climate system consists of distinct subsystems whose interplay dictates decadal variability...ENSO and it's cousins do, however, underscore the importance of natural variability in climate change."

The paper has very good non-mathematical explanations and descriptions of chaotic and coupled systems and its attractors

Environmental Reporting in a Post Truth World. Dr. David Blackall  (University of Wollongong) has published an interesting paper at Sage. In a very clear and easy to understand language he gives many examples how the media ignore major scientific results that they find "inconveniant" or ""dissenting". His conclusions: "...journalists need to understand science...they need to question the key players and to look to the agendas that may be driving them..."

Climate-driven variability in the occurrence of major floods across North America and Europe

Hurricanes and climate change: Brand-new paper by Hodgins et al. "Climate-driven variability in the occurrence of major floods across North America and Europe" published in ScienceDirect: "The number of significant trends was about the number expected due to chance alone"

Read this excellent contribution "What you need to know & are not told about hurricanes" on the Fabius Maximus blog.

Transatomic White Paper 2.1. (Nov.2016) TransAtomicPower is a new startup company created by former young MIT researchers. Its aim is to develop a molten salt nuclear reactor (a modification of the ORNL type) that is inherently safe, creates less than half spent fuel as the actual PWR's, is proliferation resistent and runs for decades providing stable, carbon-free base-load power, and possibly load following for grids impacted by intermittent wind/solar producers.
"Paleoclimate Cycles are Key Analogs for Present Day (Holocene) Warm Period" Renée Hannon, a geoscience advisor at the University of Texas at Dallas, has a very good guest comment at WUWT. Look what will happen when this warm period is going to end similarly to the previous one.
 I really appreciate her conclusion:
"Because the astronomical processes affecting significant climate changes are beyond human control our focus should be on adaptation rather than climate manipulation. It is not a question if cooling will occur but simply a question of when."
It is with great sadness that I have to inform that Prof. Istvan Marko has passed away on July 31th. I. Marko was a regular professor of organic chemistry at the UCL (Université catholique de Louvain, Belgium), and a courageous and outspoken climate realist. His many writings and presentations on climate matters were first class science, crystal clear and often very witty. Look at this interview (2016), and these two videos ([1] [2] in French, Agora Erasmus 2015).

Here links to 4 pdf's, the last one being a presentation given for the Rotary Club in Luxembourg, 2016: [1] [2] [3] [4]

Pronounced differences between observed and CMIP5 simulated multidecadal 2 climate variability in the twentieth century

An important new paper in GRL by Kravtsov & Callicutt on the failure of the IPCC CMIP5 model ensemble to correctly represent oceanic oscillations:"The observed internal variability exhibits a pronounced multidecadal mode with a distinctive spatiotemporal signature, which is altogether absent in model simulations..."

What happened to the traditional role of skepticism in climate science? I am a great fan of Forrest M. MIMS III whom I admire for his qualities of a long standing exceptional "maker", his publications on electronics and an outstanding book on the Mauna Loa research station (look here). This "hors norme" inventor and builder is also the designer of the Microtops instruments we use at meteoLCD for measuring the total ozone column.
He is a climate realist and a strong defender of the virtue of skepticism in science. Read here his comment in WUWT
New Insights on the Physical Nature of the Atmospheric Greenhouse Effect Deduced from an Empirical Planetary Tempertaure Model

A new paper by Nikolov and Zeller in "Environment Pollution and Climate Change" finds that global average near surface temperature for many celestial bodies depends only on solar irradiance and atmospheric pressure: no need to introduce greenhouse gases to explain the thermal  enhancement at the surface! Read also  blog on this important paper.

Fatalities at wind turbines may threaten population viability of a migratory bat A new paper by Frick et al. in Biological Conservation (Feb.2017) pours cold water on the naive beliefs that wind power may easily save the planet: "...we show that mortality from wind turbines may drastically reduce population size and increase the risk of extinction"
Private Benefit of CO2 and its Social Cost New paper by Prof. Richard TOL (University of Sussex):"The private benefit of carbon (411 $/tCO2) is much higher than the social cost of carbon (12 $/tCO2)."
Nucléaire et Eolien: Etude comparée de démantèlement Very interesting article (in French) by Jean Pierre Riou with surprising results:
cost for nuclear decommissioning: 1.85 €/MWh
cost for wind turbine removal:       4.32 €/MWh

Acceleration in European Mean Sea Level?

This is an excellent new paper by Phil J. Watson in the Journal of Coastal Research (Jan.2017) titled:  (note the question mark!).In short: no acceleration, relative sea-level changes are modest  and are negative in regions where uplifting due to glacial rebound is high (Baltic).
More on the blog.
a very good article (in French) on the many problems of  measuring sea-level with mm precision.

Delayed warming hiatus over the Tibetan Plateau New paper by An et al. finds that the Tibetan Plateau and China cooled down by about 0.2°C during last decade.
Diminishing number of weatherstations

Look at this graph from NOAA showing how the number of land-based weather stations has plummeted during the 1990's. What is more intriguing is that the percentage of air port located stations increased from 40% to 75%: is the measured warming a surprise?
Read this article of Prof. Fred Singer on the subject.

Berliner-Kreis: Klima- und Energie Standpunkt A position of the "Berliner-Kreis" group of conservative CDU members which question and disagree with the official "Merkel" policy (02Jun2017)
About intellectuals and climate alarmism From Frits Bolkestein, the former Dutch minister and European Commissioner. The link shows the English translation of the original Dutch article): "Censorship looms large in the field of climatology, which is not conducive to balanced decision-making...Why do so many intellectuals take pleasure in predicting catastrophes? Is it because they relish attention by the media? Or has it anything to do with Christian guilt feelings?"
Thoughts on the Public Discourse over Climat Change

Discussion on an article by Prof. Richard Lindzen (emerited, MIT) published the 25th April 2017."The accumulation of false and/or misleading claims is often referred to as the ‘overwhelming evidence’ for forthcoming catastrophe."

Tokamak Energy A private UK company is developing a small tokamak-style fusion reactor and achieved its first plasma creation. The company plans to have a small fusion reactor ready to deliver energy into the electricity grid in 2030
Was wäre wenn wir alle elektrisch fahren würden?

Caustic article by physicist Vince Ebert in "Spektrum der Wissenschaften" (19 März 2017): "Um 30 Kilogramm Benzin zu ersetzen, brauchen Sie derzeit eine moderne Lithiumionen-Batterie, die rund 900 Kilogramm wiegt...wir bräuchten sogar knapp 140 neue Kraftwerke oder 220 000 Windräder oder eine Fotovoltaikanlage von der Größe des Saarlands, um den zusätzlichen Strombedarf zu decken"

Cosmic Rays, Solar Activity and Changes in the Earth's Climate New 2017 paper by Russian scientists (Science Academy, Moscow State University) Y.I.Stozhkov et al. (link to paywalled version). They predict (as many others did before) a coming cooling, based on spectral analysis of past climate and correlation of global temperature change with the measured flux of cosmic particles in the lower 0.3 to 2.2 km atmosphere. This paper is refreshingly short and very readable!
A more extensive blog comment is here.
Energiewende - Index Deutschland A new report from McKinsey says that "...Die Kosten steigen weiter....Zentrale Ziele werden verfehlt und rücken in immer weitere Ferne...CO2 Ausstoss weit über dem Limit....das Preisniveau für deutschen Haushaltsstrom liegt 47.3% über dem europäischen Durchschnitt".This report bites and hurts!

Climate models for the layman

An excellent must read new briefing paper by Prof. Judith Curry (ex. GeorgiaTech): "... there is a secular warming trend at least since 1800 (and possibly as long as 400 years) that cannot be explained by carbon dioxide... "

Exxon Mobile 2017 Outlook for Energy: A view to 2040 The part of renewables remains rather modest (less than 15%, with wind and solar extremely poor), the total of carbon-free energy (which includes nuclear) about 22%, which leaves still 78% for fossil fuels.
"Tanktourismus-Bericht" Luxemburg 2016 Dr. Dieter Ewringmann from the FiFo Institute (Köln) wrote a report on Luxembourg's pump tourism (i.e. the costs and benefits of selling large quantities of fuel at the pump to drivers from abroad). Read my comments here (with links to short and full versions of the report). All parts (1,2,3 and 4) of the discussion are now on-line.
Third Industrial Revolution Lëtzebuerg

The great "Third Industrial Revolution Lëtzebuerg" report by Jeremy Rifkin has been released.I wrote a multi-part discussion of this 475 page blockbuster in my blog. Links to short and full version are included.

Earth climate identification vs. anthropic global warming attribution Prof. Philippe de Larminat (from Ecole Centrale de Nantes), a specialist in systems theory, has published a very interesting paper in Elsevier's "Annual Reviews in Control". He applies systems theory to the climate data and finds that, contrary to what the  IPCC says, "the natural contributions by solar and internal variability could be the dominant factor in recent global warming".
Excellent and clear paper with some not too difficult maths!
