Alarmists mark an artificial deadline, still pretending government-driven limits can be put on long-term climate variations and attempting to reduce CO2 levels in the atmosphere, which hasn’t happened anyway. Cue the usual well-worn phrases about tackling climate change, emissions etc.

For the first time, global warming has exceeded 1.5C across an entire year, according to the EU’s climate service.

World leaders promised in 2015 to try to limit the long-term temperature rise to 1.5C, which is seen as crucial to help avoid the most damaging impacts, says BBC News.

This first year-long breach doesn’t break that landmark “Paris agreement”, but it does bring the world closer to doing so in the long-term.

Solar Protons Are Raining Down on Earth

Sometimes known as a Solar particle event:
These particles can penetrate the Earth’s magnetic field and cause partial ionization of the ionosphere. Energetic protons are a significant radiation hazard to spacecraft and astronauts.


It’s warming, but not as they thought they knew it. ‘Everybody has lots of ideas, but it doesn’t quite add up.’ Aerosols, undersea volcano, El Niño, ‘new processes’ – the list of suspects goes on, but nothing convincing so far. Settled science has been unsettled, but persists with its usual assertions blaming humans anyway.
– – –
It’s no secret human activity is warming the planet, driving more frequent and intense extreme weather events and transforming ecosystems at an extraordinary rate, claims Phys.org.

But the record-shattering temperatures of 2023 have nonetheless alarmed scientists, and hint at some “mysterious” new processes that may be under way, NASA’s top climatologist Gavin Schmidt tells AFP.

The Polar Vortex Wobbled in December

Unusual but not unheard of.
– – –
‘Since the December outbreak of PSCs [polar stratospheric clouds], which ended around Christmas, the polar stratosphere has warmed more than 30 degrees Celsius.’


This must put a dent in the credibility of at least some supposedly climate-related satellite data. On the positive side, a significant chunk of the alleged global carbon dioxide problem disappears, as the carbon cycle of a large region turns out to be self-balancing. The CO2 struck off, so to speak, is ‘equivalent to about 10% of annual emissions from the burning of fossil fuels’.
– – –
The forests and grasslands of northern tropical Africa take in about as much carbon dioxide in the wet season as they release in the dry season, according to a new study based on observations from aircraft.

The findings contradict earlier research that relied on satellite data and found that these ecosystems may be adding significantly more carbon to the atmosphere than they absorb over the course of a year, says Phys.org.

The research, published in the journal Global Biogeochemical Cycles, highlights the difficulty of measuring carbon dioxide from space and the need for more frequent and robust observations from both the air and ground.

Of course it does, but there seems a hint of surprise in the findings. It’s long been known that colder water absorbs more atmospheric CO2, just as warmer water absorbs less. Anyone familiar with fizzy drinks knows the story, or ought to. The article here announces that ‘the oceans present vast and promising potential for storing carbon dioxide’. Surely this is not regarded as news? As for potential, it’s always happened.

The recent cold spell has plunged South Korea into a deep freeze, resulting in the closure of 247 national parks, the cancellation of 14 domestic flights, and the scrapping of 107 cruise ship voyages, says Phys.org.

While the cold snap brought relief by significantly reducing the prevalence of particulate matter obscuring our surroundings, a recent study indicates that, besides diminishing particulate matter, it significantly contributes to the heightened uptake of carbon dioxide by the East Sea.

According to research conducted by a team of researchers, including Professor Kitack Lee from the Division of Environmental Science & Engineering at Pohang University of Science and Technology (POSTECH) and Professor Tongsup Lee and So-Yun Kim from the Department of Oceanography at Pusan National University, the cold atmosphere in the Arctic is influencing the absorption of carbon dioxide by the East Sea.

We quote the last part of this Phys.org article, headed: ‘A planet Earth in a fragile equilibrium.’ Somehow the model finds that once the oceans have eventually evaporated ‘we would even reach 273 bars of surface pressure and over 1,500°C’. This seems a bit unlikely on the face of it as it’s three times the surface pressure, and temperature [note the link between those two] of Venus despite being nearly 40% further away from the Sun. We note that it’s not unheard of for climate models to over-predict temperature effects.

Talkshop note – the article earlier states:
One of the key points of the study describes the appearance of a very peculiar cloud pattern, increasing the runaway effect, and making the process irreversible. “From the start of the transition, we can observe some very dense clouds developing in the high atmosphere. Actually, the latter does not display anymore the temperature inversion characteristic of the Earth atmosphere and separating its two main layers: the troposphere and the stratosphere. The structure of the atmosphere is deeply altered,” says Chaverot.

A planet Earth in a fragile equilibrium.

With their new climate models, the scientists have calculated that a very small increase of the solar irradiation—leading to an increase of the global Earth temperature, of only a few tens of degrees—would be enough to trigger this irreversible runaway process on Earth and make our planet as inhospitable as Venus.

An Outbreak of Polar Stratospheric Clouds

An unusual temperature drop in the polar stratosphere.

NASA (2008) said:
Scientists recently discovered that polar stratospheric clouds, long known to play an important role in Antarctic ozone destruction, are occurring with increasing frequency in the Arctic. These high altitude clouds [which] form only at very low temperatures help destroy ozone in two ways.

We’re informed that ‘scientists have identified more than 230 of these greenings occurring about every 21,000 years over the past eight million years.’ (Ice ages may account for the numerical shortfall). Climate models aren't able to simulate these greenings, or at least not their magnitude. The period they identify is the combined precession cycle, i.e. the beat period of the tropical and anomalistic orbits (years) of the Earth (when the difference between the number of each reaches 1). Inevitably it’s about the energy received from the Sun.

Algeria’s Tassili N’Ajjer plateau is Africa’s largest national park, says The Conversation (via Phys.org).

Among its vast sandstone formations is perhaps the world’s largest art museum. Over 15,000 etchings and paintings are exhibited there, some as much as 11,000 years old according to scientific dating techniques, representing a unique ethnological and climatological record of the region.

Curiously, however, these images do not depict the arid, barren landscape that is present in the Tassili N’Ajjer today.

This was found to have been going on ‘during past warm periods’ (what caused those?), so we may wonder what difference a bit more now is likely to make. It’s admitted that scientists need to ‘understand better the role of hydrates in the climate system’ – or if they have one worth getting agitated about?

An international team of researchers led by Newcastle University found that as frozen methane and ice melts, methane – a potent greenhouse gas – is released and moves from the deepest parts of the continental slope to the edge of the underwater shelf, says EurekAlert.

They even discovered a pocket which had moved 25 miles (40 kilometres).

Publishing in the journal Nature Geoscience, the researchers say this means that much more methane could potentially be vulnerable and released into the atmosphere as a result of climate warming.

Methane hydrate

Methane hydrate, also known as fire-ice, is an ice-like structure found buried in the ocean floor that contains methane. Vast amounts of methane are stored as marine methane under oceans.

Time to dial down some over-excitable climate claims perhaps. The actual mechanism has been observed elsewhere before, but ‘not all downslope winds are katabatic‘. Effects can vary according to local conditions.

Himalayan Glaciers fight back to preserve themselves, but for how long? — asks Eurekalert.

An international team of researchers, co-led by Professor Francesca Pellicciotti of the Institute of Science and Technology Austria (ISTA), explains a stunning phenomenon: rising global temperatures have led Himalayan glaciers to increasingly cool the air in contact with the ice surface.

The ensuing cold winds might help cool the glaciers and preserve the surrounding ecosystems. The results, found across the Himalayan range, were published in Nature Geoscience.

Again it turns out that climate modellers don’t understand cloud effects too well. As this article bluntly puts it: ‘The interactions of atmospheric aerosols with solar radiation and clouds continue to be inadequately understood and are among the greatest uncertainties in the model description and forecasting of changes to the climate. One reason for this is the many unanswered questions about the hygroscopicity of aerosol particles.’ — Other reasons aren’t discussed here. Why do we keep reading about ‘state-of-the-art’ climate models when they clearly have a long way to go to merit such a description? Any forecasts they produce should be treated with great caution, to say the least.
– – –
The extent to which aerosol particles affect the climate depends on how much water the particles can hold in the atmosphere, says Phys.org.

The capacity to hold water is referred to as hygroscopicity (K) and, in turn, depends on further factors—particularly the size and chemical composition of the particles, which can be extremely variable and complex.

Through extensive investigations, an international research team under the leadership of the Max Planck Institute for Chemistry (MPIC) and the Leibniz Institute for Tropospheric Research (TROPOS) was able to reduce the relationship between the chemical composition and the hygroscopicity of aerosol particles to a simple linear formula.

Biology has been underestimated. Anything that relies on photosynthesis just takes whatever CO2 molecules it can get for its needs, regardless of current climate theories.
– – –
New research published in Science Advances paints an uncharacteristically upbeat picture for the planet, says Phys.org.

This is because more realistic ecological modeling suggests the world’s plants may be able to take up more atmospheric CO2 from human activities than previously predicted.

Despite this headline finding, the environmental scientists behind the research are quick to underline that this should in no way be taken to mean the world’s governments can take their foot off the brake in their obligations to reduce carbon emissions as fast as possible. [Talkshop comment – smell the fear of losing funding].

Simply planting more trees and protecting existing vegetation is not a golden-bullet solution but the research does underline the multiple benefits to conserving such vegetation.

“Plants take up a substantial amount of carbon dioxide (CO2) every year, thereby slowing down the detrimental effects of climate change, but the extent to which they will continue this CO2 uptake into the future has been uncertain,” explains Dr. Jürgen Knauer, who headed the research team led by the Hawkesbury Institute for the Environment at Western Sydney University.

“What we found is that a well-established climate model that is used to feed into global climate predictions made by the likes of the IPCC predicts stronger and sustained carbon uptake until the end of the 21st century when it accounts for the impact of some critical physiological processes that govern how plants conduct photosynthesis.

“We accounted for aspects like how efficiently carbon dioxide can move through the interior of the leaf, how plants adjust to changes in temperatures, and how plants most economically distribute nutrients in their canopy. These are three really important mechanisms that affect a plant’s ability to ‘fix’ carbon, yet they are commonly ignored in most global models” said Dr. Knauer.

Photosynthesis is the scientific term for the process in which plants convert—or “fix”—CO2 into the sugars they use for growth and metabolism. This carbon fixing serves as a natural climate change mitigator by reducing the amount of carbon in the atmosphere; it is this increased uptake of CO2 by vegetation that is the primary driver of an increasing land carbon sink reported over the last few decades.
. . .
Silvia Caldararu, Assistant Professor in Trinity’s School of Natural Sciences, was involved in the study. Contextualizing the findings and their relevance, she said, “Because the majority of terrestrial biosphere models used to assess the global carbon sink are located at the lower end of this complexity range, accounting only partially for these mechanisms or ignoring them altogether, it is likely that we are currently underestimating climate change effects on vegetation as well as its resilience to changes in climate.

“We often think about climate models as being all about physics, but biology plays a huge role and it is something that we really need to account for.”

Biomass on the move [image credit: Drax]


Denounced by one opponent as ‘an accounting gimmick’ and ‘double counting’. The whole biomass from trees industry is once more outed as little more than a giant subsidy-grabbing confidence trick, from energy-intensive conversion of wood into pellets all the way to so-called carbon capture. Where are the real world benefits in this hugely expensive system?
– – –
Environmental groups are taking the UK government to court on Monday (13 November) over plans to spend billions on Biomass with Carbon Capture and Storage (BECCS), a technology aimed at removing CO2 from the atmosphere that is also being promoted by the European Union, says Euractiv.

Plaintiffs say BECCS technology relies on flawed accounting assumptions because it sees the carbon captured from wood burning as negative emissions when the process is at best neutral from a climate perspective.

“The government’s rationale for BECCS as providing negative emissions violates international carbon accounting protocols underpinning the Paris Agreement, to which the UK is a signatory,” said a statement from The Lifescape Project and the Partnership for Policy Integrity (PPI), two environmental groups that are the complainants in the case.

“Burning forest biomass and relying on BECCS for negative emissions will not contribute to the government’s legal obligation to achieve net zero by 2050,” they warned.

There’s still a long way to go though: “We want to know how those factors are impacting the ice sheets.” Researchers conclude “it’s essential to enhance our models, particularly in representing sea ice dynamics.”
– – –
As the world continues to warm, Antarctica is losing ice at an increasing pace, but the loss of sea ice may lead to more snowfall over the ice sheets, partially offsetting contributions to sea level rise, according to Penn State scientists. — Phys.org reporting.

The researchers analyzed the impacts of decreased sea ice in the Amundsen Sea in West Antarctica and found the ice-free ocean surface leads to more moisture in the atmosphere and heavier snowfalls on the ice sheet, the team reported in the journal Geophysical Research Letters.

While the additional snowfall is not enough to offset the impacts of melting ice, including it in climate models may improve predictions of things like sea level rise, said Luke Trusel, assistant professor of geography at Penn State and co-author of the study.

A choice between overheating and lung damage doesn’t appeal much, giving would-be climate controllers a new conundrum for their models to grapple with. Another excuse to wheel out catastrophe fears again.

Air pollution, a global scourge that kills millions of people a year, is shielding us from the full force of the sun, says Euractiv.

Getting rid of it will accelerate climate change. That’s the unpalatable conclusion reached by scientists poring over the results of China’s decade-long and highly effective “war on pollution”, according to six leading climate experts.

The drive to banish pollution, caused mainly by sulphur dioxide (SO2) spewed from coal plants, has cut SO2 emissions by close to 90% and saved hundreds of thousands of lives, Chinese official data and health studies show.

Forecaster highlights the jetstream over the UK [image credit: BBC]


The research here finds ‘no significant change to the phase speed of waves in the Northern Hemisphere, particularly over Europe, in the last 40 years’. But in the Southern Hemisphere it’s a somewhat different picture.
– – –
Heavy precipitation, wind storms, heat waves—when severe weather events such as these occur they are frequently attributed to a wavy jet stream, says Phys.org.

The jet stream is a powerful air current in the upper troposphere that balances the pressure gradient and Coriolis forces. It is still not known whether the jet stream is really undergoing changes at decadal timescales and, if so, to what extent.

“There are various theories as to what we can expect from the jet stream in future. However, these are all based on highly idealized assumptions,” said Dr. Georgios Fragkoulidis of the Institute of Atmospheric Physics at Johannes Gutenberg University Mainz (JGU).

A NASA sounding rocket mission will launch three rockets during the 2023 annular eclipse in October to study how the sudden drop in sunlight affects our upper atmosphere, says Phys.org.

On Oct. 14, 2023, viewers of an annular solar eclipse in the Americas will experience the sun dimming to 10% its normal brightness, leaving only a bright “ring of fire” of sunlight as the moon eclipses the sun.

Those in the vicinity of the White Sands Missile Range in New Mexico, however, might also notice sudden bright streaks across the sky: trails of scientific rockets, hurtling toward the eclipse’s shadow.

El Niño graphic [credit: NOAA]


Climate alarmists have been waiting nearly 8 years, since the last significant El Niño, for another chance to claim natural climate variation as an expression of their chosen non-natural theories. Tremble – or not – as the study authors predict ‘a cascade of climate crises’.
– – –
A strong El Niño event is going to wreak havoc on global surface temperature and trigger several climate crises in 2023–2024, according to researchers from the Institute of Atmospheric Physics (IAP) of the Chinese Academy of Sciences. [Talkshop comment – the hype has already started].

The El Niño event, known for releasing massive heat into the atmosphere, is poised to change atmospheric circulation patterns, influence tropical-extratropical interactions, and impact subtropical jets, monsoons, and even polar vortices, and finally results in a rapid surge in Global Mean Surface Temperature (GMST), says Phys.org.

The study was published in The Innovation Geoscience on Sept. 15.
