The 2023 global warming spike was driven by the El Niño–Southern Oscillation

by S.P. Raghuraman et al., Oct 2024 in EGU-APCPapers

Abstract

Global-mean surface temperature rapidly increased 0.29 ± 0.04 K from 2022 to 2023. Such a large interannual global warming spike is not unprecedented in the observational record, with a previous instance occurring in 1976–1977. However, why such large global warming spikes occur is unknown, and the rapid global warming of 2023 has led to concerns that it could have been externally driven. Here we show that climate models that are subject only to internal variability can generate such spikes, but they are an uncommon occurrence (p = 1.6 % ± 0.1 %). However, when a prolonged La Niña immediately precedes an El Niño in the simulations, as occurred in nature in 1976–1977 and 2022–2023, such spikes become much more common (p = 10.3 % ± 0.4 %). Furthermore, we find that nearly all simulated spikes (p = 88.5 % ± 0.3 %) are associated with El Niño occurring that year. Thus, our results underscore the importance of the El Niño–Southern Oscillation in driving the occurrence of global warming spikes such as the one in 2023, without needing to invoke anthropogenic forcing, such as changes in atmospheric concentrations of greenhouse gases or aerosols, as an explanation.

Brown Bears Lived In The 73°N Siberian Arctic 3500 Years Ago…Today Their Northern Boundary Is 65°N

by K. Richard, Oct 14, 2024 in NoTricksZone

A new study provides still more evidence the Arctic was warmer than it is today as recently as a few thousand years ago.

In 2020 the well-preserved carcass of a Yakutian brown bear (Ursus arctos) was discovered buried in permafrost on the terrain of the treeless tundra Bolshoy Lyakhovsky Island in the Arctic Ocean, 73°N.

The Yakutian brown bear currently occupies only the forested regions of Eurasia, with a northern limit of northern Yakutia (Republic of Sakha), 65°N.

The female bear’s age has been dated to approximately 3500 years ago, during the Middle to Late Holocene. At that time the Arctic was warm enough at that latitude to support vegetation (grasses, shrubs) that only persist in the northern Yakutia region today.

The authors suggest brown bears may have been permanent residents of the Siberian Arctic’s islands from about 5000 years ago until a few thousand years ago, when, as today, the Arctic became too cold for the vegetation production requisite for their sustenance.

El Niño fingered as likely culprit in record 2023 temperatures

by P. Voosen, Oct 10, 2024 in Science

For the past year, alarm bells have been going off in climate science: Last year’s average global temperature was so high, shooting up nearly 0.3°C above the previous year to set a new record, that human-driven global warming and natural short-term climate swings seemingly couldn’t explain it. Some, like famed climate scientist James Hansen, suggestedEarth is entering an ominous new phase of accelerated warming, driven by a rapid decline in sunlight-dimming air pollution. Others, like Gavin Schmidt, director of NASA’s Goddard Institute for Space Studies, said the rise might represent a “knowledge gap,” some new climate feedback that might tip the planet toward a future even warmer than models predict.

Now, a new series of studies suggests most of the 2023 jump can be explained instead by a familiar climate driver: the shifting waters of the tropical Pacific Ocean. The combination of a 3-year-long La Niña, which suppressed global temperatures from 2020 to 2022, followed by a strong El Niño could account for the unexpected temperature jump, the work suggests. “Earth can do this,” says Shiv Priyam Raghuraman, a climate scientist at the University of Illinois Urbana-Champaign, who led one study.

During La Niña, strong trade winds push warm surface water west along the equator toward Indonesia and pull up a fountain of deep, cold water in the eastern Pacific that helps cool the planet. During El Niño, the winds collapse, allowing warm water to slosh east and shut off the ocean air conditioner. Continuer la lecture de El Niño fingered as likely culprit in record 2023 temperatures →

First published 9 October 2024

Well-preserved fossils uncovered in France have revealed new insights into one of the biggest invertebrates to ever walk on Earth.

Arthropleura was a millipede-like animal which lived more than 300 million years ago during the Carboniferous Period, with some individuals reaching more than two metres long.

The head of one of history’s biggest arthropods has been revealed in detail for the first time.

Arthropleura is an arthropod, the group containing insects, crustaceans, arachnids and their relatives. For many years, only fossils of its body survived, which saw it placed among the earliest millipedes. Now, the discovery of the first complete head has revealed a surprising twist.

While the new fossils are not from fully grown Arthropleura, some of which reached 2.6 metres long, they reveal important characteristics. Most notably, the head has some features of early centipedes, suggesting millipedes and centipedes might be more closely related than previously accepted.

NOAA’s Data Shows Rising Average Temps Driven By Growth And Measurement Flaws—Not Climate Change

by L. Hamlin, Oct 7, 2024 in ClimateChangeDispatch

NOAA’s U.S. contiguous U.S. summer measured minimum and maximum temperature trends (June through August) over the period 1895 through 2024 (shown below from NOAA’s Climate at a Glance Times series data website) show clear and distinct differing temperature trend increasing growth compared to the calculated average temperature trend outcome. [emphasis, links added]

The minimum temperature trend outcomes after 1985 climb significantly faster than the maximum measured temperature trend outcomes. U.S. population data shows an increase of about 100 million during the 1980 to 2023 period.

Since the average temperature is not a measured value but instead the calculated mathematical average of the minimum and maximum measured temperatures {(Tmax + Tmin)/2}, the average temperature-calculated trend outcome is controlled and dominated by the much larger increase occurring in the minimum-measured temperature trend versus the maximum measured temperature trend.

Prophets Of Doom: Why A New 2024 Climate Report Is Fueled By Fear, Not Facts

by Dr M. Wielicki, Oct , 2024 in ClimateChange Dispatch 

The recent article published in BioScience, “The 2024 state of the climate report: Perilous times on planet Earth,” is a parade of exaggerated claims and half-truths, a propaganda piece designed to scare the public into adopting misguided policies while turning a blind eye to the real drivers of human progress.

Climate Activists Frustrated by IPCC’s Refusal to Link Extreme Weather with Carbon Emissions

by C. Morrison, Oct 10, 2024 in WUWT

Last June, the state-reliant BBC reported that human-caused climate change had made U.S. and Mexico heatwaves “35 times more likely”. Nothing out of the ordinary here in mainstream media with everyone from climate comedy turn ‘Jim’ Dale to UN chief Antonio ‘Boiling’ Guterres making these types of bizarre attributions. But for those who closely follow climate science and the assessments of the Intergovernmental Panel on Climate Change (IPCC), “such headlines can be difficult to make sense of”, observes the distinguished science writer Roger Pielke. In a hard-hitting attack on the pseudo-scientific industry of weather attribution, he states: “neither the IPCC nor the underlying scientific literature comes anywhere close to making such strong and certain claims of attribution”.

Pielke argues that the extreme position of attributing individual bad weather events is “roughly aligned” with the far Left. “Climate science is not, or at least should not serve as a proxy for political tribes,” he cautions. But of course it is. The Net Zero fantasy is a collectivist national and supra-national agenda that increasingly relies on demonising bad weather. With global temperatures rising at most only 0.1°C a decade, laughter can only be general and side-splitting when IPCC boss Jim Skea claims that British summers will be 6°C hotter in less than 50 years. Two extended temperature pauses since 2000 have not helped the cause of global boiling. In addition there are increasing doubts about the reliability of temperature recordings by many meteorological organisations that seem unable to properly account for massive urban heat corruptions.

The 2024 Atlantic hurricane season is well underway, with forecasters predicting active and potentially dangerous conditions. … [emphasis, links added]

In late September, Hurricane Helene slammed into Florida’s Gulf Coast and drenched the Southeast, with devastating flooding taking a deadly toll in the mountains of North Carolina.

Here are the top 10 deadliest recorded hurricanes in U.S. history, according to the National Weather Service.

10. Last Island hurricane (1856)

The Last Island hurricane killed 400 people after slamming into the Louisiana coast in August 1856.

The highest points of the island were left under five feet of water in the wake of the storm, with the resort hotel and surrounding gambling establishments destroyed, according to NOAA.

The island itself was devastated, left void of vegetation, and split in half, NOAA said.

UAH Global Temperature Update for August, 2024: +0.88 deg. C

by P. Homewood,  Sep 2, 2024 in NotaLotofPeople KnowThat

From Dr. Roy Spencer’s Global Warming Blog.

The Version 6 global average lower tropospheric temperature (LT) anomaly for August, 2024 was +0.88 deg. C departure from the 1991-2020 mean, up slightly from the July, 2024 anomaly of +0.85 deg. C.

Persistent global-averaged warmth was (unusually) contributed to this month by the Southern Hemisphere. Of the 27 regions we routinely monitor, 5 of them set record-warm (or near-record) high monthly temperature anomalies in August, all due to contributions from the Southern Hemisphere:

Global land: +1.35 deg. C

Southern Hemisphere land: +1.87 deg. C

Southern Hemisphere extratropical land: +2.23 deg. C

Antarctica: +3.31 deg. C (2nd place, previous record was +3.37 deg. C, Aug. 1996)

Australia: +1.80 deg. C.

The linear warming trend since January, 1979 now stands at +0.16 C/decade (+0.14 C/decade over the global-averaged oceans, and +0.21 C/decade over global-averaged land).

New Study: Human Emissions ‘Irrelevant’ In Determining Changes In Atmospheric CO2 Since 1959

by K. Richard, Sept 2, 2027 in NoTricksZone

“The main factor governing the annual increase in atmospheric CO2 concentration is the SST [sea surface temperature] rather than human emissions.” – Ato, 2024

Another day, another new scientific paper has been published reporting efforts to curb anthropogenic CO2 emissions are “meaningless.”

In this study multiple linear regression analysis was performed comparing SST versus anthropogenic CO2 emissions as explanatory factors and the annual changes in atmospheric CO2 as the objective variable over the period 1959-2022.

The model using the SSTs (NASA, NOAA, UAH) best explained the annual CO2 change (regression coefficient B = 2.406, P = <0.0002), whereas human emissions were not shown to be an explanatory factor at all in annual CO2 changes (regression coefficient B = 0.0027, P = 0.863).

Most impressively, the predicted atmospheric CO2 concentration using the regression equation derived from 1960-2022 SSTs had an extremely high correlation coefficient of r = 0.9995.

Thus, not only is the paradigm that says humans drive atmospheric CO2 changes wrong, but “the theory that global warming and climate change are caused by human-emitted CO2 is also wrong.”

“SST has been the determinant of the annual changes in atmospheric CO2 concentrations and […] anthropogenic emissions have been irrelevant in this process, by head-to-head comparison.”

New Study: CO2’s Atmospheric Residence Time 4 Years…Natural Sources Drive CO2 Concentration Changes

by K. Richard, Aug 30, 2024 in WUWT

“Clearly, the atmospheric CO2 observation data are not consistent with the climate narrative. Rather, they contradict it.”  – Koutsoyiannis, 2024

Per a new study, the Intergovernmental Panel on Climate Change (IPCC) utilizes “inappropriate assumption and speculation,” as well as non-real-world models of “imaginary data,” to claim CO2 emissions derived from fossil fuel burning function “weirdly,” far differently in the atmosphere than CO2 molecules derived from natural emissions (e.g., plant respiration, ocean outgassing) do.

“The ambiguity is accompanied by inappropriate assumptions and speculations, the weirdest of which is that the behavior of the CO2 in the atmosphere depends on its origin and that CO2 emitted by anthropogenic fossil fuel combustion has higher residence time than when naturally emitted.”

While the IPCC acknowledges emissions from natural sources have an atmospheric residence time of only 4 years, they have simultaneously constructed model outputs that assert CO2 molecules derived from fossil fuel emissions remain in the atmosphere for hundreds, thousands, tens of thousands, even several one hundred thousands of years.

Per the IPCC:

“15 to 40% of an emitted CO2 pulse [from anthropogenic emissions] will remain in the atmosphere longer than 1000 years, 10 to 25% will remain about ten thousand years, and the rest will be removed over several hundred thousand years.”

“Carbon dioxide (CO2) is an extreme example, its turnover time is only about 4 years because of the rapid exchange between the atmosphere and the ocean.”

Again, a four-year residence time for natural CO2, but hundreds of thousands of years residence time for CO2 molecules elicited from fossil fuel burning. It would seem just about any result can be derived from imaginary data.

…

Instead of relying on models built on assumption and speculation, Dr. Koutsoyiannis utilizes a well-established, hydrology-based theoretical framework (refined reservoir routing, or RRR) combined with real-world CO2 observations to robustly conclude the residence time for all CO2 molecules, regardless of origin, is between 3.5 and 4 years.

The applied theoretical results match the empirical results so closely (e.g., an empirical mean of 3.91 years vs. a theoretical mean of 3.94 years at Barrow, and an identical 3.68 years for both empirical and theoretical means at Mauna Loa from 1958-2023) that the theoretical framework can be said to be “close to perfect.” In other words, the consistency of the applied calculation with real-world observations provides robust evidence that CO2 residence time is likely close to this range.

In contrast, the calculated probability for the modeled, imaginary-data-based claim that the residence time for a CO2 molecule persists for over 1000 years is 10⁻⁶⁸, which means the probability value is “no different from an impossibility.”

The Solar Control of Climate: A Review

by D. Archibald,  Aug 28, 2024 in TheWentworthReport

This review was prepared for a Zoom interview on the Sun’s role in climate. Some say carbon dioxide is the controlling variable in climate. That notion is discredited, most recently by a study on variation in the Earth’s albedo. As the following figure from that study shows, all of the atmosphere’s temperature rise this century mirrors the reduction in albedo with no room for a contribution from carbon dioxide:

…

This is consistent with the logarithmic heating effect of carbon dioxide. Half of the warming from atmospheric carbon dioxide comes from the first 20 ppm and then rapidly drops away from there. Carbon dioxide is tuckered out as a greenhouse gas:

 

From the current 423 ppm, each 100 ppm increase results in a temperature rise of only 0.1°C. The atmosphere will only get to about 600 ppm before we run out of rocks we can dig up and burn. So the warming effect from carbon dioxide is only good for another 0.2°C. There is no human on our planet sensitive enough to feel a 0.2°C difference in temperature. And this story doesn’t have a happy ending. There is 50 times as much carbon dioxide in the oceans than in the atmosphere, so the 800-year turnover of the oceans will take 98% of the carbon dioxide humans have added to the atmosphere down to the Davy Deep and we won’t see it again. A couple of hundred years from now our descendants will be lamenting the annual decline in crop yields due to falling carbon dioxide levels.

Global Temperature updated for August 2024

by C. Best, Aug 27, 2024 in SciTravelOpinion

The global temperature anomaly for August was 1.27 deg.C relative to a 1961-1990 baseline. These results use GCHN monthly land temperatures combined with HadSST4 ocean temperatures. I use a novel method to calculate this using a 3D spherical triangulation of the earth’s surface. This is shown below.

The monthly trends relative to the 1961-1990 baseline are shown below.

Temperature trends

One of the problems with Global Warming is that the underlying temperature trends are superimposed on far larger but shorter natural variability cycles (El Nino). Therefore it makes little sense to push for action based on just one month’s temperature. It may even take another decade to be certain that average temperatures really have exceeded  1.5 C.

A far better method to determine when this will happen is based on using Icosahedral grids with decadal averaging 

The observed stable decadal trend shows that the Paris Agreement to limit warming to 1.5C since the preindustrial level will very likely be exceeded in 2032

Florida’s Fossil Fuel Renaissance: Why the Sunshine State is Laughing Off Climate Hysteria

by C. Rotter, Aug 24, 2024 in WUWT

Maguire’s article, which is as much a lament as it is a piece of journalism, paints Florida as the villain in a story where the rest of the country is the hero, gallantly marching toward a green utopia. But here’s the kicker: Florida’s doing just fine, and the people who live there know it. Let’s break down the absurdity of the climate scolds and see why Florida’s energy strategy is not only sensible but downright smart.

Fossil Fuels: The Workhorse of Florida’s Energy Grid

According to Maguire, Florida’s reliance on fossil fuels—gasp—has actually increased in 2024, a move that he seems to think is tantamount to environmental heresy. “Florida reverses energy transition by cranking fossil fuel use,” his headline wails, as if the state had suddenly decided to reverse gravity. But let’s get real: fossil fuels, particularly natural gas, are the backbone of Florida’s energy grid for a very simple reason—they work. When the summer sun is beating down, and everyone’s cranking up the AC, no one wants to hear that their power has been cut because the wind isn’t blowing or a cloud passed over a solar farm.

Maguire points out that over 80% of Florida’s electricity has come from fossil fuels since the beginning of June, the highest share in over three years. He compares this to the national average of 62.4% and Texas’s 62%, as if this somehow proves Florida is an outlier in the worst way. But let’s be honest: these are numbers that should make Floridians proud. While the rest of the country toys with unreliable renewables, Florida is ensuring that its citizens have a reliable, affordable energy supply.

The Reality of Renewable Energy

Renewables sound great on paper, don’t they? Free energy from the sun and wind—what’s not to love? But here’s where the rubber meets the road: renewables aren’t ready for prime time, especially not in a state like Florida, where reliability isn’t just a luxury, it’s a necessity. Imagine the chaos if millions of Floridians were left in the sweltering heat because the sun decided to take a day off. Florida’s summer is no joke, and neither is the demand for electricity. The state’s grid needs to be as robust as a linebacker, not as fragile as a flower.

And it’s not like Florida has completely ignored renewable energy. Florida Power & Light (FPL), the largest utility in the state, is leading a solar charge, aiming to install 30 million solar panels by 2030. But here’s the kicker—Florida’s leaders know that solar is a supplement, not a substitute. That’s why they haven’t thrown the baby out with the bathwater and abandoned fossil fuels.

The Atlantic Is Cooling at a Mysteriously Fast Rate After Record Warmth

by P. Homewood, Aug 25, 2024 in NotaLotofPeopleKnowThat

For over a year, surface temperatures in the Atlantic Ocean hit new highs, but that trend has reversed at record speed over the past few months, and nobody knows why.

In June, temperatures in the Atlantic were 2 to 5 degrees Fahrenheit (1 to 3 degrees Celsius) hotter than normal in much of the ocean, with some areas getting as much as 9 degrees F (5 degrees C) warmer than average. Those temperatures weren’t a one-off, as the Atlantic had regularly seen record-breaking levels since March 2023. That year marked the fourth in a row that the world’s oceans set new heat records.

The hot water was partially a result of human-caused climate change, but it was also due to a particularly strong El Niño in 2023 and 2024. But that system appears to have passed, according to the National Oceanic and Atmospheric Administration.

NOAA data shows Atlantic sea surface temperatures have cooled at a surprising rate since May. Since June began, temperatures have been a degree or two Fahrenheit colder than normal for this time of year. That means El Niño will likely be replaced by its counterpart, La Niña, a weather system that allows cold water to rise to the surface of the Atlantic, some time between September and November. Both El Niño and La Niña are complex systems driven by trade winds, solar heating, and rainfall in the tropic regions, and can be difficult to predict. Still, the sudden shift in Atlantic temperatures has been puzzling, and nobody seems to know why it’s happened so quickly.

“We’ve gone through the list of possible mechanisms, and nothing checks the box so far,” Frans Philip Tuchen, a postdoctoral student at the University of Miami, told New Scientist.

https://gizmodo.com/the-atlantic-is-cooling-at-a-mysteriously-fast-rate-after-record-warmth-2000488967

.So they do not have a clue why the Atlantic has suddenly got colder, but they think they know that global warming made it hotter in the first place, even though there is no physical for the claim that a slightly warmer atmosphere can make any measurable difference to ocean temperatures!

They also get their knickers in a complete twist stating that El Ninos in the Pacific raise SSTs in the Atlantic!

Study: Sea Levels Rose 4.7 Centimeters Per Year 8200 Years Ago – 30 Times Faster Than Modern Rates

by K. Richard, Aug 26, 2024 in NoTricksZone

The modern rate of sea level rise is not even close veering outside the range of natural variability.

A new study reminds us that, 8200 years ago, near-global sea levels rose 6.5 meters in a span of just 140 years. This is 470 centimeters per century, 4.7 centimeters per year, during a period when CO2 levels were alleged to be a “safe” and stagnant 260 ppm.

Image Source: Nunn et al., 2024

To put this change rate in perspective, global sea levels rose at a rate of 1.56 millimeters per year from 1900 to 2018, including 1.5 mm per year rate during the more recent period from 1958-2014 (Frederikse et al., 2020, Frederikse et al., 2018). This is just under 16 centimeters per century or sixteen hundredths of a centimeter (0.16 cm) per year

Yet More Reasons Why Green Hydrogen Is Going Nowhere

by F. Menton, Aug 28, 2024 in WUWT

In the fantasy of the zero-emissions electricity future, there will either be regular devastating blackouts, or something must back up the intermittent wind and solar generation. In New York we call that imaginary something the “DEFR” (Dispatchable Emissions Free Resource). But what is it? Nuclear has been blocked for decades, especially in the blue jurisdictions that are most aggressively pursuing the wind/solar future. Batteries are technologically not up to the job, and also wildly too expensive. That leaves hydrogen. Anybody with another idea, kindly speak up.

I’ve had several posts discussing the question of whether hydrogen could do this job, for example this one on February 14, 2024, and this one on July 20. Those posts focused on the initial cost of making hydrogen by electrolysis from water. That cost turns out to be a multiple of the cost of producing natural gas by drilling into rock (for comparable energy content). From time to time I have alluded to other potential problems with having hydrogen replace natural gas in the electricity system — things like leaks, explosions, and the need for an entire new infrastructure of pipelines and trucks to carry the stuff and power plants to burn it. But until now I haven’t found a detailed study on just how bad these additional problems might be.

Now comes along an August 18 article in a peer-reviewed journal called Energy Science & Engineering, with the title “A review of challenges with using the natural gas system for hydrogen.” The article was linked on August 23 by Paul Homewood at the Not a Lot of People Know That site, and then further linked by Watts Up With That on August 24.

The lead author is a guy named Paul Martin. Unusually for an article in such a journal, no academic affiliation is given for Mr. Martin. Looking him up on LinkedIn, I find that he is not an academic, but rather identifies himself as a “chemical process development expert” who has spent “years in industry,” and is currently with Spitfire Research, Inc., which in turn states that it specializes in “consulting for a decarbonized future.” Mr. Martin then identifies several of his co-authors on the paper as a “team of people at the Environmental Defense Fund.” That information may well color your perception of what Martin, et al., have to say in their paper.

Math Confirms Foolishness of Climate Alarmism

by G. Wrightstone, Aug 11, 2024 in WUWT

The science of climate change often is presented in complicated language that speaks of computer models and the theoretical inputs and outputs thereof and concludes that the globe is on the verge of “boiling.” Well, leave it to three physicists — steeped in calculus and such arcane matters as the behavior of molecules and the nuclear charge of atoms — to simplify the analysis and arrive at a much less alarming determination.

“Straightforward calculations … show that eliminating U.S. CO2 emissions by the year 2050 would avoid a temperature increase of 0.0084 degrees Celsius,” states a brief paper authored by Drs. Richard Lindzen, Massachusetts Institute of Technology; William Happer, Princeton University; and William A. van Wijngaarden, York University, Toronto. On the Fahrenheit scale, the value of averted warming is 0.015 degrees.

In short, the amount of warming averted by eliminating CO2 emissions in the United States would be too small to measure. The paper bolsters the position of those who argue that a changing climate is the product of natural forces, that human-induced carbon dioxide emissions can have only a minuscule effect on global temperature, and that CO2 is a valuable plant food and not a pollutant.

Rather than using theoretical assumptions about various factors that are fed into computers, the paper’s calculation relies almost exclusively on “observable data” that are widely accepted and publicly available, says Dr. Happer.

“This is something anybody with a calculator can figure out,” said the scientist, who may be best known for his contribution to a laser-based technology for destroying incoming ballistic missiles as part of the so-called Star Wars program of the 1980s.

Natural Gas Industry’s Smear of Coal Is False and Self-Defeating

by G. Wrightstone, July 22, 2024 in RealClearEnergy

Smearing coal has become a marketing strategy of a natural gas industry that embraces pseudoscientific views of coal combustion as being hazardous.

In so doing, gas supporters give credence to a fallacious regulatory regime of the Environmental Protection Agency (EPA), which erroneously classifies carbon dioxide as a pollutant and assigns health effects to low-level pollution without scientific proof. To boot, a false representation of coal, oil and natural gas as environmental bogeymen is perpetuated.

Perhaps the most enthusiastic user of this foolish ploy is Toby Rice, CEO of Pittsburgh-based EQT Corp., who introduced two years ago a global plan to replace coal with liquefied natural gas. Promoting his product as a “decarbonizing force” in June at a RealClearEnergy conference, the head of the country’s largest gas producer (check the video link above to see his part), said:

“What we would like to do at EQT … is focus people on a really practical solution that will allow us to provide energy security for the world and address people’s concerns over global emissions. And that path is very simple: transition the world from coal to gas.”

Although natural gas emits less carbon dioxide than coal when burned, the underlying premise of Rice’s pitch rests on the popular myth that CO2 emissions will overheat the planet. The organization we lead, the CO2 Coalition, has overwhelming evidence from top scientists showing that increasing atmospheric carbon dioxide not only poses no danger but is beneficial to plant growth and crop production.

The ‘Climate Emergency’ is a Myth, Says Nobel Prize Winner John Clauser. Here’s Why He’s Right

by Dr R. Kalveks, June 8, 2024 in DailySceptic

In a recent lecture, Nobel Laureate physicist John Clauser exposed how the Intergovernmental Panel on Climate Change (IPCC) models and analyses, which are relied upon by politicians and activists to support claims of a ‘climate crisis’, do not meet basic standards of scientific enquiry. Clauser received his Nobel prize in 2022 for the observational measurement of quantum entanglement and understands well the problem of distinguishing a physical signal from background noise.

Clauser shows that, when corrected for the IPCC’s error prone arithmetic and statistics, the observational data do not support the power imbalance claimed to be responsible for global warming. Furthermore, the outputs of climate models are at variance with the observational record. Clauser discusses the roles of convection, clouds and their variability in providing a negative feedback mechanism, and proposes that this acts as a thermostat that stabilises surface temperatures. Clauser’s conclusion is that claims of a ‘climate crisis’ lack scientific substance and that Net Zero policies are an unnecessary hindrance.

Energy Flows in the Climate System

It is useful to start with a simplified depiction of the solar energy flow that reaches the Earth, its transformation by the Earth’s climate system and the resulting (mostly thermal) energy flow that leaves the Earth’s atmosphere. This is shown in Figure 1, taken from a recent IPCC report.

The IPCC diagram shows an energy imbalance, being the difference between the incoming visible and UV solar radiation 340 W/m2, less the amount reflected (100 W/m2), less the outgoing infra-red (IR) thermal radiation (239 W/m2). The claimed imbalance at the Top of the Atmosphere is 0.7 W/m2 (give or take 0.2) and the IPCC asserts that this is driving the continuing warming of the climate system.

Table. 1. Top of Atmosphere Energy Flows. Energy flows at the top of the Earth’s atmosphere, with their errors as per Figure 1. The balance is calculated from its components.

The radiation measurements necessary for this calculation are carried out at different wavelengths by instruments carried by satellites, and observational errors are inevitable. Combining the uncertainty ranges in the incoming, reflected and outgoing streams shown in Table 1, by using the standard statistical Root Mean Square rule, shows that the error margin in the calculated imbalance is actually 3 W/m2, some 15 times greater than the 0.2 W/m2 error margin claimed by the IPCC. In short, there is no observedenergy imbalance. The claimed imbalance of 0.7 W/m2 is swamped by observational error, and, from a scientific perspective, it is described by Clauser as a “fudge”.

New Study: Central Europe Was ‘2-5°C Warmer Than Present’ Throughout Most Of The Holocene

by K. Richard, July 22, 2024 in NoTricksZone

There were millennia during the past glacial (when CO2 levels were under 200 ppm) that were as warm or warmer than today.

Four central Europe reconstructions, using collected evidence from disparate biomarkers, indicate there were periods (for example, 54,000 to 51,000 years ago, the Bølling–Allerød interstadial, 14,700 years ago) during the last glacial when temperatures were as warmer than (or similar to) today (Zander et al., 2024).

Temperatures throughout the Holocene (8,000 to 4,000 years ago), when CO2 hovered around 265 ppm, were 3.5°C (and up to 5°C) warmer than today. Modern temperatures are among the coldest of the last 10,000 years.

Carbon Dioxide and a Warming Climate are not problems

by A. May & M. Crok, May 29, 2024 in AmJEconSociology

Dear signatories of the Clintel World Climate Declaration

 

We are very excited to announce the publication of our peer reviewed paper titled “Carbon dioxide and a warming climate are not problems“. It was published in the American Journal of Economics and Sociology. The paper was written by Andy May, retired petrophysicist and currently climate writer and blogger, and Clintel director Marcel Crok.

Crok and May coordinated the ambitious Clintel project to analyse the IPCC AR6 report, which last year led to the publication of the Clintel book The Frozen Climate Views of the IPCC. In the book we document serious errors and biases in the latest IPCC report.
The new paper is largely based on the many interesting findings of that book.

The new paper gets a lot of attention, mostly positive and some critical (of course). This has led to an impressive attention score (which gives an indication of how much the paper is being discussed on blogs and on X/twitter). The paper is already in the 99th percentile.

 

It was a little expensive (2330 euros) to make the paper open access so we decided not to do that this time. But our submitted version can be downloaded for free.

Signatories of the World Climate Declaration could help us boosting the paper even further by writing about it on blogs and/or discussing the paper on X (twitter).

Andy May has been responding very promptly to some of the criticism on the paper, see here, here and here.

 

The full abstract of the paper can be read below:

Cooling The Niño

by W. Eschenbach, July 14, 2024 in WUWT

This is a two-part post. The first part is to correct an oversight in my recent post entitled Rainergy.

The second part is to use that new information to analyze the effect of clouds on the El Nino region.

So, to the first part. In my post Rainergy, I noted that it takes ~ 80 watts per square meter (W/m2) over a year to evaporate a cubic meter of seawater. Thus, the evaporation that creates the ~1 meter of annual rain cools the surface by – 80 W/m2.

Then the other day I thought “Dang! I forgot virga!”

Virga is rain that falls from a cloud but evaporates completely before it hits the ground.

Causality Analysis Finds Temperature Changes Have Determined CO2 Changes Since The Phanerozoic

by K. Richard, July 15, 2024 in NoTricksZone

Popular claims that CO2 changes drive temperature changes currently or throughout the distant past “are based on imagination and climate models full of assumptions.”

A comprehensive new study details a stochastic assessment determination of the sequencing of CO2 variations versus temperature variations since the 1950s, over the last 2,000 years (the Common Era), and throughout the last 541 million years.

The robust conclusion is that the causality direction – with the understanding that causes lead and effects lag – clearly shows the temperature changes lead and CO2 changes lag on yearly, decadal, and centennial/millennial scales. In other words, “the reverse causality direction [CO2]→T should be excluded.”

The claim that CO2 increases drive temperature changes is thus a “narrative” only, as the claim that “humans, through their emissions by fossil fuel burning, are responsible for the changes we see in climate” can be regarded as a “non-scientific issue.”

 

The author has had a series of peer-reviewed scientific papers published supporting this same T→CO2 conclusion (Koutsoyiannis et al., 2022, Koutsoyiannis et al., 2020, Koutsoyiannis et al., 2023, Koutsoyiannis, 2024, Koutsoyiannis, 2024) in just the last few years.

Since these papers challenge the prevailing anthropogenic global warming (AGW) narrative so acutely, Dr. Koutsoyiannis has understandably been the recipient of antagonism bordering on vitriol from AGW proponents. This includes comments from peer-reviewers. So, in an apparent effort to foster transparency, he has made the peer reviewers’ comments on this latest paper public. Here is the link to these commentaries:
