Unfortunately climate alarmists are too far down their manic road to be halted by the views of Einstein or anyone else, but worth a look anyway.
[H/T Chaeremon]


The hypothesis of global warming from man made CO2 depends on a much-repeated narrative about CO2 trapping infrared (IR) photons leaving the earth. Although a beguilingly simple idea, a host of assumptions underlie it. One of these is that the radiative photonic absorption – emission interactions of the trace gas CO2 dominate heat movement in the atmosphere. And it turns out, this argument, a pillar of the global warming theory, is false – it was refuted in advance by none other than Albert Einstein in 1917.

In this 1917 paper:

Einstein says this about radiative heating of a gas:

“During absorption and emission of radiation there is also present a transfer of momentum to the molecules. This means that just the interaction of radiation and molecules leads to a velocity distribution of the latter. This must surely be the same as the velocity distribution which molecules acquire as the…

Well, knock me down with a feather. Real world data can expose flaws in ‘greenhouse gas’ infected climate models, which are unable to model El Niño and La Niña events, and mostly predict much more warming than actually occurs.

New research shows that naturally occurring climate variations help to explain a long-standing difference between climate models and satellite observations of global warming, says

Satellite measurements of global-scale changes in atmospheric temperature began in late 1978 and continue to the present.

Relative to most model simulations, satellite data has consistently shown less warming of Earth’s lower atmosphere.

This is one of several questions to be investigated by a Norwegian research team. The ultimate one may be: what happens to hydrogen’s hoped-for role in the big push for so-called green energy, if the findings are unfavourable to current climate theory?

Hydrogen is an attractive [Talkshop comment: perhaps, but expensive] alternative to fossil fuels, especially for powering trucks, ships and planes, where using batteries isn’t so easy, says TechXplore.

Hydrogen is an attractive alternative to fossil fuels, especially for powering trucks, ships and planes, where using batteries isn’t so easy.

Batteries quickly become too large and heavy if these large transport vessels and vehicles are going to travel far.

As a result, hydrogen is being discussed like never before. Both Norway and the EU have said they will invest more in hydrogen in the years ahead.

Key to the usefulness of climate models as tools for both scientists and policymakers is the models’ ability to connect changes in atmospheric greenhouse gas levels to corresponding shifts in temperature, says Eos.


Ned Nikolov, Ph.D. Has written to me with news of the presentations he made at this years AMS meeting. It’s vital we get people to understand the implications of the discoveries he and Karl Zeller have made. With our western governments jumping aboard the ‘Green New Deal’ and ‘NetZero’ bandwagons, we will need to work hard to rise awareness of viable alternative hypotheses for ‘climate change’ and ‘global warming’ which better explain the phenomena we can measure around us. Ned and Karl’s work should be given proper attention, because it strives for universality and general application of physics solar system wide, rather then treating Earth as a ‘special case’.

Two studies presented at the American Meteorological Society’s 34th Conference on Climate Variability and Change in January 2021 employed a novel approach to identify the forcing of Earth’s climate at various time scales. The new method, never attempted in climate science before, relies on the fundamental premise that the laws of nature are invariant across spacetime.


Another pillar of ‘settled’ climate science trembles. It’s described as ‘one of the largest uncertainties faced by climate scientists.’ Is there a list of these uncertainties somewhere?

The impact of atmospheric aerosols on clouds and climate may be different than previously thought, reports

That is the conclusion of cloud researcher Franziska Glassmeier from TU Delft. The results of her study will be published in Science on Friday, January 29th.

Cloud decks cover vast stretches of the subtropical oceans. They cool the planet because they reflect incoming sunlight back to space.

Air pollution in the form of aerosols—particles suspended in the atmosphere—can increase this cooling effect because it makes clouds brighter.

The cooling effect of pollution offsets part of the warming effect of greenhouse gases. How much exactly, is one of the largest uncertainties faced by climate scientists.

Ship tracks

A striking illustration of clouds becoming brighter as a result of aerosols, is provided by shipping emissions in the form of “ship tracks.” These are visible as bright lines within a cloud deck that reveal the paths of polluting ships that travel beneath the clouds.

“Such ship tracks are a good example of how aerosol effects on clouds are traditionally thought of, and of how they are still represented in most climate models,” says Glassmeier.

But according to the cloud researcher, ship tracks do not tell the whole story.

In the midst of pandemic-related hard times, airline survival means looking for fuel savings ahead of trivia like emissions of harmless trace gases. A mix of nature and new tech might do the trick.

Airlines could save fuel and reduce emissions on transatlantic flights by hitching a better ride on the jet stream, new research has shown.

Scientists at the University of Reading have found that commercial flights between New York and London last winter could have used up to 16% less fuel if they had made better use of the fast-moving winds at altitude, says TechXplore.

New satellites will soon allow transatlantic flights to be tracked more accurately while remaining a safe distance apart.



Greetings Earthlings, or should we say ‘habitable-zone-dwelling asteroid dodgers’? We even have the right amount of atmosphere — not too little (like Mars) or too much (like Venus), and the essential oxygen.

Pure chance is the reason that Planet Earth has stayed habitable for billions of years.

A new study has found that it’s nothing more than good luck that has kept our world full of life, reports I-news.

Scientists at the University of Southampton have carried out a mass simulation of climate evolution of 100,000 randomly generated planets.

Each planet was simulated 100 times with random climate-altering events occurring each time in order to see if habitable life could be sustained for three billion years like on Earth.

Methane from cattle accounts for a significant amount of global warming [Talkshop comment: evidence-free assertion] — startup Zelp has a comfortable and stylish solution, says Wired.

There are 1.6 billion cattle on Earth, and their burps and farts are becoming a big problem.

Cows expel methane, a colourless and odourless gas which is approximately 84 times more potent than carbon dioxide when it comes to warming the planet.


Is it a coincidence that we’re just past the end of the lowest sunspot cycle for over a century?

Dec. 28, 2020: Something strange is happening 50 miles above Antarctica. Or rather, not happening. Noctilucent clouds (NLCs), which normally blanket the frozen continent in December, are almost completely missing. These images from NASA’s AIM spacecraft compare Christmas Eve 2019 with Christmas Eve 2020:

“The comparison really is astounding,” says Cora Randall of the University of Colorado’s Laboratory for Atmospheric and Space Physics. “Noctilucent cloud frequencies are close to zero this year.”

NLCs are Earth’s highest clouds. They form when summertime wisps of water vapor rise up from the poles to the edge of space. Water crystallizing around specks of meteor dust 83 km (~50 miles) above Earth’s surface creates beautiful electric-blue structures, typically visible from November to February in the south, and May to August in the north.

A crucial point: Noctilucent clouds form during summer. And that’s the problem. Although summer officially started in Antarctica one week…

Interesting, but the climate hysteria machine will keep inventing its hobgoblins regardless until someone turns off the funding.

PA Pundits - International

By David Wojick, Ph.D. ~

Using a new observational approach to an old but most important question, CLINTEL President Guus Berkhout finds that about 62% of the atmospheric CO2 increase is due to natural sources, not human emissions. The study then looks at the implications for drastic CO2 reduction measures, finding that these measures will not stop the atmospheric increase. Actually, they will have very limited effect. Hence the title of the report is “Managing the Carbon Dioxide Content in the Earth’s Atmosphere“.

Professor Berkhout’s approach is based on proven technology in geophysical imaging. He calls his method spectral ‘fingerprint detection (FPD)’, because it looks at the relationship between fine-grained details of the atmospheric CO2 increase and anthropogenic emissions over time by computing auto and cross correlation functions.

Note that in the spectral FPD approach knowledge about the existence of different CO2 isotopes (C12 and C13) is…

Nobel prize-winning physicist CTR Wilson

‘Charles Thomson Rees Wilson, CH, FRS (14 February 1869 – 15 November 1959) was a Scottish physicist and meteorologist who won the Nobel Prize in Physics for his invention of the cloud chamber.
. . .
The invention of the cloud chamber was by far Wilson’s signature accomplishment, earning him the Nobel Prize for Physics in 1927. The Cavendish laboratory praised him for the creation of “a novel and striking method of investigating the properties of ionized gases”. The cloud chamber allowed huge experimental leaps forward in the study of subatomic particles and the field of particle physics, generally. Some have credited Wilson with making the study of particles possible at all.’ — Wikipedia.

A potted biography, including cloud chamber images and a diagram of the global atmospheric electrical circuit, can be found here.

Photosynthesis: nature requires carbon dioxide

This seems open to interpretation. Does it lead to the possibility that most CO2 rise is natural, and therefore all attempted reductions are an even bigger waste of time, money and resources than they were anyway? Here the BBC serves up another dollop of warmist assertions it can’t or won’t try to justify, presumably in an attempt to prevent any inconvenient notions about greenhouse gas theory from entering its audience’s heads.

The global response to the Covid-19 crisis has had little impact on the continued rise in atmospheric concentrations of CO2, says the World Meteorological Organization (WMO).

This year carbon [dioxide] emissions have fallen dramatically due to lockdowns that have cut transport and industry severely, says BBC News.

But this has only marginally slowed the overall rise in concentrations, the scientists say.

The purple-and-green, atmospheric light show nicknamed STEVE just got even stranger, says Science News.

STEVE, short for Strong Thermal Emission Velocity Enhancement, is a sky glow that appears south of the northern lights (SN: 3/15/18).

STEVE’s main feature is a mauve band of light formed by a stream of plasma flowing westward through the atmosphere — a different phenomenon from the one that gives rise to auroras (SN: 4/30/19).

But STEVE’s purple arc is often accompanied by a “picket fence” of vertical green stripes.

Clouds again: “For 50 years, people have been making climate projections, but all of them have had a false representation of clouds”, says a top atmospheric science professor who served as a lead-author of Chapter 7, “Cloud and Aerosols” for the Fifth Assessment Report of the Intergovernmental Panel on Climate Change.
Despite this glaring deficiency in climate models, governments insist on framing energy policies on the assertion that human ’emissions’ will be the main cause of any observed or future global climate change.

Above the Atlantic Ocean, puffy white clouds scud across the sky buffeted by invisible trade winds.

They are not ‘particularly big, impressive or extended,” says Dr. Sandrine Bony, a climatologist and research director at the French National Centre for Scientific Research. “But they are the most ubiquitous clouds on Earth.”

Clouds are one of the biggest question marks in global climate models, and a wild card in predicting what will happen to the climate as temperatures rise, says

They play a vital role in how much of the sun’s radiation makes it into and gets trapped in our atmosphere.

The more clouds there are, the more radiation bounces off their tops and is reflected back into space; it also means that if there are more clouds, the radiation reflected by Earth gets trapped.


Another outbreak of trace gas climate paranoia, with vehicle air conditioning in the firing line this time. But attempts to choke off supplies of supposedly offending refrigerants have created a market for smugglers bringing cheap HFCs from China.

The EU’s legislation on fluorinated gases, adopted in 2014, needs an overhaul “to increase ambition in line with the European Green Deal” and “better prevent” an ongoing surge of illegal imports coming from China, an EU official told EURACTIV.

Demand for F-gases, a family of chemicals used as a refrigerant, has increased steadily since they were introduced in the early 1990s to replace the ozone-depleting chlorofluorocarbons (CFCs).

But F-gases are also among the most potent greenhouse gases [Talkshop comment: assertion with no supporting evidence, as usual] and are now also being phased out as a result.

Countries across the world took unprecedented action in the first few months of 2020 to control the spread of COVID-19, says The Conversation (via

At its peak, one-third of the world’s population was in lockdown.

Around the world, car travel fell by 50%, the number of flights plummeted by 75% and industrial activity fell by around 35%.

With so many cars parked, airplanes grounded and factories closed, global carbon dioxide (CO₂) emissions fell by around 17% compared with the same period in 2019.


Since Arrhenius was mentioned in the ‘conversation with Roger Pielke Senior’ post this week, let’s look at his science efforts a bit more closely — with Ron Clutz.

Science Matters

“Those who cannot remember the past are condemned to repeat it.”–George Santayana 1905

Interesting that Svante Arrhenius was elevated as the founder of AGW belief system. He was ignored for many decades after Knut Ångström and his assistant Herr Koch showed that reducing CO2 concentrations did not affect the amount of IR absorbed by the air. That’s almost as interesting as discovering that shutting down the global economy over fear of Covid19 has little effect on atmospheric CO2 concentrations.

As a fellow Scandinavian, Ångström agreed with Arrhenius that his projected warming would be a good thing, even in the lower estimates Svante made later on. Still, Ångström had two objections to Arrhenius’ conjecture about global warming from increasing CO2. In 1900, Herr J. Koch, laboratory assistant to Knut Ångström, did not observe any appreciable change in the absorption of infrared radiation by decreasing the concentration of CO2 up to a…

Got any spaces left on that 2020 bingo card? Pencil in “another Dust Bowl in the Great Plains”, suggests

A study from University of Utah researchers and their colleagues finds that atmospheric dust levels are rising across the Great Plains at a rate of up to 5% per year.

The trend of rising dust parallels expansion of cropland and seasonal crop cycles, suggesting that farming practices are exposing more soil to wind erosion.

And if the Great Plains becomes drier, a possibility under climate change scenarios, then all the pieces are in place for a repeat of the Dust Bowl that devastated the Midwest in the 1930s.

The European Union’s Earth observation program said Tuesday that the ozone hole over Antarctica has swelled to its largest size and deepest level in years, reports

Experts at the Copernicus Atmospheric Monitoring Service said a strong, stable and cold polar vortex has driven the expansion, and called for greater international efforts to ensure countries abide by an international accord to phase out use of ozone-depleting chemicals.

Vincent-Henri Peuch, who heads the service, said in a statement that the ozone hole was “definitely” among the largest in the last 15 years.
