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

|Energy and the Hydrogen Economy||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?

|A reality check on renewables||
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 yesterday solution".

|Die Welt vergrünt||
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 "Die Weltwoche" article in German)
|The warming effects of CO2 are benign||by Sanjeev Sabhlok (an economist) in the Times of India: "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.

|Presentation by Laurent ALEXANDRE||
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||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):
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."

|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)

|The State of the Climate 2018||
Read the latest report by Prof. Ole Humlum
(Uni. Oslo, Uni.Center Svalbard, creator of the
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."
|The New Energy Economy: an exercise in wishful thinking.||
Read this well written comment
by Mark Mills (Manhattan
Institute) which pours some cold water on
overhyped future energy scenarios:"This
“new energy economy” rests on the belief ... that
the technologies of wind and solar power and battery
storage are undergoing the kind of disruption
experienced in computing and communications,
dramatically lowering costs and increasing
efficiency... An energy revolution will come only
from the pursuit of basic sciences... These will
emerge from basic research, not from subsidies for
yesterday’s technologies... Wind turbines, solar
arrays, and batteries, meanwhile, constitute a small
source of energy, and physics dictates that they
will remain so."

|Iceland's glaciers are expanding!||"The researchers were shocked by the discovery that all of Iceland’s glaciers, including Vatnajökull, Langjökull, Hofsjökull and Mýrdalsjökull, have expanded in the last twelve months". Just a question: why were the researchers shocked? Have good news become bad news in activist climatology? Read also here about growing Greenland glacier.|
|5 continent aviation neutron survey||
We know that trans-continental flights at high
altitude are exposed to much higher radioactive
radiation (about 50 times that at ground-level). A
new research campaign focused on neutrons,
and found (rather surprisingly) that over 40% of the
radioactive dose comes from cosmogenic neutrons,
which are about 10 times more effective in creating
cellular damage than gamma rays.

Lying with science: a guide to myth debunking
||Read this article by Matt Ridley in "The Spectator": "Newspapers, politicians and pressure groups have been moving smoothly for decades from one forecast apocalypse to another (nuclear power, acid rain, the ozone layer, mad cow disease, nanotechnology, genetically modified crops, the millennium bug…) without waiting to be proved right or wrong...Some people are willing to forgive exaggeration and error if it is in a good cause, like increasing concern about plastics or climate change. This is a risky strategy because it encourages a Trump-like refusal to believe evidence even when that evidence is good"|
|La transition énergétique est inutile, coûteuse et injuste||
writes Rémy Prud'homme in a report
contributing to the "Grand Débat National" in
Prud'homme is a former professor invited to the MIT, directeur adjoint at the OECD, consultant for the
World Bank etc..., so this report is not the work of
"Une politique forte, qui contraindrait les pays de l’OCDE à réduire de moitié leurs rejets annuels d’ici à 2050, réduirait cette augmentation de la moyenne des températures du globe à 0,23 °C. Par rapport à l’évolution « naturelle », cette lourde politique de transition aurait donc pour effet de réduire la moyenne des températures de 0,027 °C"
|Was tragen CO2 und die Sonne zur globalen Erwärmung bei ?||Very interesting and easy to follow presentation by Prof. Hermann Harde (Uni. Helmut-Schmit, Hamburg). Using a simple but complete 2 layer model (which includes convection and evaporation) he suggests that the observed global warming is caused to 65% by solar influence and to 35% by rising CO2 levels.|
|Grid-Scale Storage||Very interesting new report on electricity storage by Prof. Jack Ponton (Uni. Edinburgh) on storage technologies of intermittent electricity producers like solar, wind and tidal. The report is easy to read, sober and realistic. "There seems to be no possibility that any existing storage technology can handle the intermittency of wind generation and make it effectively dispatchable...Solar plus battery storage is probably already cost-competitive for locations in or near the tropics...Only storage as hydrogen could provide summer to-winter storage (in the UK), but cost and lack of suitable storage sites would rule out this approach...The combination of tidal stream generation and pumped storage (are) worth consideration. However, the number of tidal sites with sufficient stream velocity to provide useful generation in the neap tide-season may be limited"|
|Climate change denier||
There is a
reprint of a comment of Prof.
G. Brown from Duke University on the use of the
term "climate change denier" in WUWT. His
text starts after the title "UPDATE" after Dr.
Bain's letter. Please read
this clear and sober comment from a theoretical
"... if one examines the complete geological record of global temperature variation on planet Earth (as best as we can reconstruct it) not just over the last 200 years but over the last 25 million years, over the last billion years — one learns that there is absolutely nothing remarkable about today’s temperatures!

|Deficiencies in the IPCC's Special Report on 1.5 Degrees||Paper by Prof. Ray Bates. Look how the global average heat content of the upper 300m water layer of the oceans varied since 1910 (ECMWF CERA-20C reanalysis ensemble). Do you notice a continuous ongoing warming? (look here at Fig.4 for more on the ECMWF reanalysis)|
Beware of the unintended consequences!
"...maybe we should think about the climate benefits of plastic" says Rachel A. Meidl (PhD)
"Simply introducing single-use plastic bans without first defining the problem and contemplating a practical, holistic plan is premature and will result in rudimentary, dead-ended and misguided policies".Read also this GWPF paper on this subject.

|The intensity of cosmic rays is increasing||
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!)
|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%

wonderful article by the Dutch journalist Marco Visscher, published at spiked-online.
|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
"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.”

|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".
|Land-use emissions play a critical role in land-based mitigation for Paris climate targets||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! (Nature Communications).|
|Highview Power storage system||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?|

|Cargo-cult statistics and scientific crisis||
An excellent paper on science, research and

Prof. Stark (Berkeley) and Saltelli (Oberta). One of

|The State of World's Beaches||
A new paper 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.
|Open letter of members of the Geological Society||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."|
|Save the oceans...stop recycling plastic||Prof. Mikko Paunio (University of Helsinky) has a very interesting paper (published by the GWPF), where he suggests to stop recycling plastics and burn it instead in incinerators. This to avoid the leakage of disused plastic shipped (by many EU countries) to Asia, where a big part finds its way into the streams and the oceans. He concludes that "Austria, Denmark and Sweden have been at the forefront ... and should be seen as environmental leaders. However, their remarkable progress in managing MSW (municipal solid waste)... is now being compromised by the EU’s new anti-incineration stance."|
|Compendium on the German Energiewende||
The "Bundesinitiative für vernünftige

Compendium on the German Energiewende,
whose "ambitious" targets for 2020 will not be
achieved (link to English translation).
The compendium says that "wind and solar energy, which seem to promise a quick fix, are not simple alternatives to fossil fuels... What we therefore need is a large-scale and generous energy research programme that covers all aspects of energy efficiency, storage, transport and generation in a technology neutral manner..."

|A Critical Look at Claims for Green Technologies||
Vaclav SMIL, emeritus professor of the University of Manitoba, published a very interesting article in the IEEE Spectrum (3Jun2018): "...many of today’s ambitions will not become tomorrow’s realities..." and concludes "While it is easy to extoll—and to exaggerate—the seductive promise of the new, its coming will be a complicated, gradual, and lengthy process constrained by many realities."

You might not agree with every statement made, but reflect on these two sentences:
1." 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."

Renée Hannon, a geoscience advisor at the
University of Texas at Dallas, has a very good
guest comment at WUWT.
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
(2016), and these two videos (
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:

|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!

|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"|

|Acceleration in European Mean Sea Level?||
This is an excellent new paper by Phil
J. Watson in the Journal of Coastal Research
(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).

|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?

|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?"|

|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!

|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!
