Dr. Lindzen – a long-time critic of IPCC-sponsored climate theories – argues, among other things, that ‘Changes in mean temperature are primarily due to changes in the tropic-to-pole difference, and not to changes in the greenhouse effect.’ Unfortunately decades at the forefront of climate research don’t count with some people unless you’re making the right alarmist noises.

Dr. Richard Lindzen’s new paper: An Assessment of the Conventional Global Warming Narrative. – Published by the Global Warming Policy Foundation – September 22, 2022:

Climate change is “a quasi-religious movement predicated on an absurd ‘scientific’ narrative. The policies invoked on behalf of this movement have led to the US hobbling its energy system.” –

“The Earth’s climate has, indeed, undergone major variations, but these offer no evidence of a causal role for CO₂.”

“Unless we wake up to the absurdity of the motivating narrative, this is likely only to be the beginning of the disasters that will follow from the current irrational demonization of CO₂.”

The Prince promotes a goal of ‘a stable climate’, which has never existed before except in someone’s imagination. Net zero fantasy rumbles on.

I hate to pour cold water on the Prince of Wales’ big night out in Boston on Friday, where he hosted the Earthshot Prize for climate change solutions, says Ross Clark @ The Spectator.

William needs all the help he can get to distract attention from his brother and sister-in-law as they continue their crazed attack on the royal family.

If we are going to have a prize which genuinely helps get us close to net zero emissions by 2050, an affordable means of carbon capture is certainly one thing you would hope would be among the five winners.

From airborne observations, these researchers find ‘trade-wind clouds are far less sensitive to global warming than has long been assumed’. Their study says: ‘Our observational analyses render models with large positive feedbacks implausible’. Consequently, they believe, extreme rise in Earth’s temperatures is less likely than previously thought.

In a major field campaign in 2020, Dr. Raphaela Vogel who is now at Universität Hamburg’s Center for Earth System Research and Sustainability (CEN) and an international team from the Laboratoire de Météorologie Dynamique in Paris and the Max Planck Institute for Meteorology in Hamburg analyzed observational data they and others collected in fields of cumulus clouds near the Atlantic island of Barbados.

Their analysis revealed that these clouds’ contribution to climate warming has to be reassessed, says Eurekalert.

“Trade-wind clouds influence the climate system around the globe, but the data demonstrate behavior differently than previously assumed. Consequently, an extreme rise in Earth’s temperatures is less likely than previously thought,” says Vogel, an atmospheric scientist.

Does the claim here that ‘almost every part of the ocean is heating up’ stand up to scrutiny? The article appears to contradict itself when stating ‘this cooling is the product of upwelling caused by the collision of a deep ocean current’ and referring to an ‘icy current’. The researchers say ‘this cooling water is fighting a losing battle with a warming atmosphere’, but deep ocean currents are by definition a long way from the surface most of the time.

A geological coincidence placed the Galapagos Islands in the line of an icy current that provides food and shelter in a warming ocean, says Hakai Magazine.

The good news might not last for long.

Pushed by climate change, almost every part of the ocean is heating up. But off the west coast of the Galapagos Islands, there is a patch of cold, nutrient-rich water. This prosperous patch feeds phytoplankton and breathes life into the archipelago.

Planetary cycles affecting climate. The study title: ‘Two annual cycles of the Pacific cold tongue under orbital precession’. Some real climate change theory to ponder.
– – –
Weather and climate modelers understand pretty well how seasonal winds and ocean currents affect El Niño patterns in the eastern equatorial Pacific Ocean, impacting weather across the United States and sometimes worldwide, says Robert Sanders, University of California – Berkeley (via Phys.org).

But new computer simulations show that one driver of annual weather cycles in that region—in particular, a cold tongue of surface waters stretching westward along the equator from the coast of South America—has gone unrecognized: the changing distance between Earth and the sun.

The cold tongue, in turn, influences the El Niño-Southern Oscillation (ENSO), which impacts weather in California, much of North America, and often globally.

In this new version, the idea that the famous body was only found due to recent warming after being under ice continuously for over 5000 years gets buried, so to speak. The sting in the tail is this: ‘the researchers also found evidence suggesting that Ötzi had not died where he was found in the gully — instead, he had been transported down the mountain by natural environmental processes’. If, as they say, he ‘had melted out of the ice many times’, those times must have occurred at various higher levels, suggesting greater warming then than we (so far) see today. This poses an awkward question or two for prevalent climate theories.
– – –
A small team of researchers affiliated with institutions in Norway, Sweden and Austria, has found evidence that suggests a flaw in the original story of how Ötzi (the Iceman) remained preserved for so long, says Phys.org.

In their paper published in the journal The Holocene, the group details what they describe as a more plausible explanation.

In 1991, a couple of German hikers came upon the remains of a man frozen in the ice in the Ötztal Alps. Testing of the remains showed the man to be from approximately 5,300 years ago.

The Talkshop doesn’t do film reviews as a rule, but we have to make an exception for this amusing one from Tony Thomas. A tale of dodgy e-mails, thwarted FOI requests, feeble inquiries, and assorted sinister goings-on. We’ll even offer a short excerpt to give readers a taste of it.

TT: The top copper rates the case as “Category A”, literally worse than a homicide investigation because it could imperil the planet, you see. “So we can expect some additional support from national counter-terrorism, Scotland Yard,” he intones. A brown lady constable (two BBC diversity boxes ticked) interjects, “Sorry, boss, but who’s been murdered?” He snaps at her, “Look at the timing! Join the dots! Three weeks before COP15 [Copenhagen]. If this is someone trying to influence the global response to climate change, then I’d say Category A is not enough!” The now chastened lady constable nods: now she gets it.

Tony Thomas writes: If I had my life to live over again, I wouldn’t change a thing, except I’d skip The Trick, a movie about the Climategate scandal that makes heroes of the villains. The BBC aired it last year, and it’s finally accessible on Britbox via my Apple TV. It’s a thriller and the hero is Dr Phil Jones, who, in 2009 when the scandal broke, was a “world renowned” top scientist on a mission to save the planet from the perils of CO2…

Vastly higher? Enormous? Staggering? – should we be shocked? No, because none of these words from the article below appear in the study itself, which notes: ‘We find that, between 1960 and 1989, sea level in the Mediterranean fell’. It then ‘started accelerating rapidly’. The study also admits: ‘The relative contributions from sterodynamic changes (i.e., changes in ocean density and circulation) and land-ice melting to this recent increase in the rate of Mediterranean sea-level rise remain unclear.’ Looks like the press release resorted to colourful language.
– – –
Scientists from the National Oceanography Centre (NOC) have discovered a substantial rise in sea-levels in the Mediterranean Sea, using a vital new method to measure changes in sea-level, says the NOC.

The study, published in Journal of Geophysical Research: Oceans, demonstrated that sea levels in the Mediterranean Sea have risen at vastly higher rates over the past 20 years compared to the entirety of the 20th century.

The study revealed that sea level in the Mediterranean Sea increased by about 7cm in the period 2000–2018.

Previous changes in sea-level rise in the Mediterranean Sea have been highly unpredictable due to limited observational data but using this latest method, scientists analysed sea-level data from tide gauges and satellites to reveal an enormous increase as a result of ocean warming and land ice-melt.

Living in Europe and feeling a bit warmer than usual this October? Ignore any Met Office reports of warm air originating from Africa and be concerned by ‘a sign of accelerating climate change’, say climate obsessives. For example, it hasn’t been ‘this hot’ in Spain, since…1961.
– – –
October morning temperatures topping 30 Celsius (86 Fahrenheit) in Spain may have brought cheer to the tourists, but they are provoking concern among environmentalists, says Phys.org.

The mercury has been rising well above the norm across vast swathes of Europe, from Spain to as far north as Sweden.

After a summer marked by repeated heatwaves across much of the continent, Europe is experiencing exceptional temperatures even as it heads into the start of autumn—a sign of accelerating climate change.

Climate alarmists love to refer to ‘heat-trapping’ greenhouse gases, but never explain how trace gases – or any gases – can trap heat in an openly convecting atmosphere. The UN also conveniently forgets that water vapour is by far the most prevalent radiative gas, while claiming ‘the warming effect of greenhouse gases has risen by nearly 50% between 1990 and 2021’. Methane is measured in parts per *billion* in the atmosphere but is still deemed good for regular alarm attempts. All grist to their COP27 mill.
– – –
The world saw a record jump in levels of methane in the atmosphere last year as the main heat-trapping greenhouse gases reached new highs, UN experts said.

The World Meteorological Organisation’s (WMO) annual bulletin shows the three main greenhouse gases – carbon dioxide, methane and nitrous oxide – all reached record high concentrations in the atmosphere in 2021, showing the world was “heading in the wrong direction” on climate change, says The Ecologist.

And potent greenhouse gas methane saw the biggest year-on-year jump in levels since measurements began nearly 40 years ago.

As another travelling circus of climate ‘delegates’ jet off to their annual conference, generating vast amounts of CO2 to get there and back, the claim that such minor trace gases in the atmosphere are a dire threat to the world gets talked up again. But we’ve heard it all before, many times.

Countries must re-prioritise climate change or the world faces catastrophe, the UN chief has told BBC News.

The researchers say ‘climate models often differ on the precise degree of future warming, largely due to their representation of clouds.’ For decades we’ve been told to believe variations in carbon dioxide are the key to any future warming, but climate model forecasts have been unable to deliver the hoped-for precision. Predicting future cloud variations looks like a tall order.

Quick Summary

— Study adds a missing piece to the climate science puzzle of simulating clouds.
— Lightness of water vapor influences the amount of low clouds.
— Some leading climate models don’t include this effect.
— Including vapor buoyancy into climate models helps improve climate forecasting.

Clouds are notoriously hard to pin down, especially in climate science, says UC Davis.

A study from the University of California, Davis, and published in the journal Nature Geoscience shows that air temperature and cloud cover are strongly influenced by the buoyancy effect of water vapor, an effect currently neglected in some leading global climate models.

Headline: ‘Derbyshire fossil study reveals insights into Peak District’s 12 million year-old climatic past’. Sounds plausible perhaps. But the article below contains a big blunder, or at least a propaganda trick. The relevant quote: ‘Today Derbyshire has a mean annual temperature of around 8°C with up to 1000mm of rain a year, 12 million years ago it was 12-18°C with 1200-1400mm of rain. This doubling of temperature was with atmospheric carbon dioxide levels similar to those predicted for 2060.’ Doubling? In Kelvin terms the increase is more like 3%, but maybe that wouldn’t sound startling enough. The expressed idea here turns out to be to promote ‘carbon capture’.
– – –
A decade-long study into unique rocks near a Derbyshire village has been uncovering the secrets of what the county and the Peak District might have looked like under a much warmer and wetter past, says Northumbria University (via Phys.org).

Although first studied over 10 years ago, the most recent investigation into geological deposits near Brassington was initiated in 2019, with an international team of researchers from Northumbria University, the British Geological Survey, Morehead State University in the U.S. and CONICET in Argentina now assessing their latest findings.

The complex techniques used can analyze the fossil pollen of plants and spores of fungi captured within the rock layer, helping to form a picture of past habitats and reconstruct likely climatic conditions far beyond our most recent understanding of the Peak District.

These researchers seem to have forgotten about the dominant role of water vapour when referring to so-called greenhouse gases – which is odd considering the topic of their study. Are they still promoting an excuse for 1970s cooling?
– – –
Small sulfate particles of diameters 0.4 µm or less from anthropogenic sources could have had a cooling effect on the climate in the 1970s, by triggering cloud formation and reflection radiation, says Hokkaido University (via Phys.org).

Global warming and climate change are one of the most pressing issues of this century.

It is well known that carbon dioxide is the most common greenhouse gas [Talkshop comment – no it isn’t, that’s water vapour by far], but what is less known is that a few anthropogenic aerosols retard the effects of greenhouse gases.

One such chemical is sulfate, which is more infamous for its role in acid rain.

Earth and climate – an ongoing controversy


Hollywood-style climate scenarios may entertain some but the science content is suspect, judging by their failure to materialise. Excessive alarmism is self-defeating in the end as more of the public switches off.

We’ve seen it splashed across news headlines: future sea-level rise that could consume the state of Florida, predicted global temperature spikes of 9 degrees Fahrenheit by 2100—threats of catastrophic climate scenarios leading to societal collapse, says Eurekalert.

But now, a University of Colorado Boulder-led team is pushing for climate scientists to put the more likely and plausible middle-range scenarios to the research forefront, instead of solely the worst-case futures.

“We shouldn’t overstate or understate our climate future,” said Matt Burgess, Cooperative Institute for Research in Environmental Sciences (CIRES) fellow, assistant professor at CU Boulder and lead on a letter published this week in Proceedings of the National Academy of Sciences (PNAS).

Researchers hope ‘to ease comparisons between climate and weather models with observations from weather instruments’, broadly speaking. In terms of modelling this is a known area of difficulty.
– – –
The Earth Model Column Collaboratory is an open-source research platform that pairs complex data with weather observations to create highly accurate climate models and forecast predictions.

Clouds come in all shapes and sizes, says Phys.org.

While we might imagine puppies or whales or breaking waves, climatologists look at them as massive bundles of water in various forms that contribute to the daily weather, and ultimately, climate.

The numbers, shapes and sizes of the liquid drops and ice crystals contained in a cloud, for example, will determine how it will scatter light or emit and absorb heat.

In response the government said it is fully committed to its legally binding net zero climate goals.

Attribution of events, known to have happened many times before, to human causes by invoking ‘the role of climate change’ in the modern era is speculation at best, as is any vague claim that humans could ‘increase the risk’ of such events. As usual, climate alarmists want people to feel guilty and nervous.

Most Australians have known drought in their lifetimes, and have memories of cracked earth and empty streams, paddocks of dust and stories of city reservoirs with only a few weeks’ storage, says The Conversation (via Phys.org).

But our new research finds over the last 1,000 years, Australia has suffered longer, larger and more severe droughts than those recorded over the last century.

These are called “megadroughts,” and they’re likely to occur again in coming decades.
