We’re Teaching Kids Scarcity in an Age of Abundance

by N. Harden, Aug 27, 2026

Students head back to classrooms this month. Many arrive already convinced their future is hopeless.

In a Lancet Planetary Health study of 10,000 young people across ten countries, 75% said the future is frightening and 56% said they believe humanity is doomed. A 2025 PNAS study found one in five Americans aged 16 to 24 is afraid to have children because of the climate. That gloom has deepened over time. In Yale’s long-running survey, the share of Americans 18 to 34 who say global warming is already harming this country rose from 40% in 2012 to 64% in 2022.

What’s causing such a dramatic shift? It could be what’s missing in the classroom. Teenagers name teachers as their leading source on climate and energy. Seventy-one percent say they learned “a lot” or “some” from a teacher, ahead of parents at 67% and social media at 63%. Yet the median high school science teacher spends one or two hours a year on the subject, and three-quarters of teachers say they have never been trained to teach it.

The teaching gap shows. Nearly three-quarters of teens believe ocean plastic is a major contributor to climate change. (It’s not.) Energy illiteracy is even worse: fewer than a third of high schoolers can name the three sources that generate most American electricity. Energy literacy scores among high school seniors fell between 2017 and 2022.

What fills the gap is the phone. Researchers at the University at Buffalo, writing last fall in Climatic Change, found that heavier social media use correlates with what they call “climate doom,” the belief that warming will collapse social and economic order. When other researchers examined 100 climate videos on TikTok, only eight cited a reputable source.

A video feed full of ignorance and despair doesn’t make a good curriculum.

Wrong, Deutsche Welle, There Is No Such Thing as a “Super El Niño,” Nor is it on Team Climate

by A. Watts, Aug 25, 2026 in WUWT

Deutsche Welle (DW) claims in “How climate change is teaming up with ‘Super El Nino” that a developing “Super El Niño,” combined with climate change, could make 2026 one of the hottest years on record while increasing the risks of heat waves, wildfires, droughts, hurricanes, and marine heat waves around the world. This is highly misleading. El Niño are long-recognized naturally recurring ocean-atmosphere cycles that have operated for thousands of years and strong El Niño events have occurred periodically throughout history, long before industrial greenhouse gas emission began to increase.

That alone should make readers skeptical.

The first red flag appears in the headline itself. There is no official meteorological definition of a “Super El Niño.”

El Niño is not a new phenomenon, nor is it evidence of climate change. Long before automobiles, coal-fired power plants, or industrial emissions existed, El Niño events periodically warmed the tropical Pacific Ocean, temporarily altering normal weather patterns around the globe. Paleoclimate records from corals, lake sediments, and other shell middens, and other proxy data show that El Niño events have repeatedly occurred for thousands of years.

Nothing about its existence is evidence of a climate crisis. DW also suggests that climate change is “teaming up” with El Niño to produce record warmth.

That statement reverses cause and effect.

El Niño transfers enormous amounts of stored ocean heat into the atmosphere. That is precisely why global temperatures often spike during strong El Niño years and then decline as La Niña conditions return. This pattern has repeated for centuries.

The strong 1997-98 El Niño produced record global temperatures.

The powerful 2015-16 El Niño did the same.

More recently, the 2023-24 El Niño contributed to another jump in global temperatures before they began moderating as the event weakened. There is nothing unprecedented about this sequence, which is made clear in the Figure below

Neither the World Meteorological Organization, the National Oceanic and Atmospheric Administration’s Climate Prediction Center, nor the American Meteorological Society recognizes “Super El Niño” as a formal scientific classification. Meteorologists describe El Niño events by measuring sea surface temperature anomalies in the Niño 3.4 region of the tropical Pacific. They may characterize an event as weak, moderate, strong, or very strong, but “Super El Niño” is largely a media invention designed to make a naturally occurring climate pattern sound unprecedented.

Scientists discover a natural Arctic cloud factory missing from climate models

by  University of Birmingham, Aug 18, 2026 in ScienceDaily

A newly discovered Arctic process can dramatically boost the number of particles that help form clouds. Near melting sea ice, sunlight reacts with chemicals released by the ocean, algae, and ice, causing cloud-seeding particles to multiply by as much as 50 times in a day. Because the active ice-edge region is growing as sea ice retreats, the effect could become increasingly important. Scientists now want to add the process to climate models to see how much it could reshape Arctic warming.
The findings, published August 5 in Nature Geoscience, come from an international team led by the University of Birmingham with collaborators in China and Spain. The researchers provide the first real-world evidence that a powerful particle-forming process occurs where Arctic sea ice meets open ocean. In this zone, marine life and sunlight help produce a chemical mixture that can seed the atmosphere with particles capable of influencing clouds.

Comparison Of Two German Weather Forecasts: From 25 Years Ago And From Today

by P. Gosselin, Aug 20, 2026 in NoTricksZone 

Escalating climate language: 25 years ago, 28°C was “pleasant”…today it is called “extremely dangerous”.

The following video link compares two different forecasts for warm summer weather but are allegedly from a couple of decades apart. I can’t be sure of their authenticity, but the language tone differences between back then and today are definitely accurate! Today, the media make summertime in Germany appear as extremely dangerous!

https://www.facebook.com/share/r/1YzSiSCk3x/

25 years ago…

The first forecast by the German weather lady is from a couple of decades ago. Here’s what she reported:

Tomorrow we’ll be getting wonderful summer weather! Temperatures will rise to a pleasant 28 to 30 degrees Celsius [82 to 86°F]. Everywhere across the country, there will be plenty of sunshine and only a few fair-weather clouds. Perfect weather for heading to the lake or having an ice cream in the beer garden. Enjoy the summer!”

Versus today

The second made recently by a German weatherman forecasts almost exactly the same weather conditions, but with alarmist tones:

Tomorrow we are facing an extremely dangerous heatwave! Temperatures will climb to a hazardous 28 to 30 degrees Celsius [82 to 86°F]. UV radiation will be extremely high, with an increased risk of high ozone levels and heatstroke. Avoid direct sunlight where possible, stay hydrated, and look out for the elderly and young children.”

Wave Goodbye to the Butterfly Effect …

by M. Jonas, Aug 18, 2026 in WUWT

… and wave as hard as you like. There’s no need to worry about disrupting Earth’s climate.

It has been a long time coming, but I have had another paper on Climate Modelling published – Chaos Theory is Void. It addresses the well-known and generally-accepted Butterfly Effect, aka Chaos Theory. I and others have felt for a long time that the Butterfly Effect exists only in models, and that Earth’s self-correcting weather/climate is too stable for the Butterfly Effect to exist to any meaningful extent in the real world. But how to prove that?

Two years ago, in GCMs Cannot Predict Climate, I described how GCMs (General Circulation Models) cannot predict climate because their iterative mechanism fails after a few weeks. Clearly the iterative mechanism itself is the problem. But how to prove that?

It all stayed on the back-burner for a while, but then I came across a paper that criticised an AI-based model for not being able to replicate the Butterfly Effect. In my previous paper I had argued that the structure of GCMs was upside-down: instead of working bottom-up from weather to climate, a climate model should work top-down with climate. Now, here was AI doing exactly what I argued for and being criticised for not having the same problem as GCMs!

Just as Hot in 1911

by P. Homewood, Aug 116, 2026 in NotaLotOfPeopleKnowThat

Hottest day of the year in the urban heat ravaged London, where temperatures are generally around three degrees higher than elsewhere:

…

Back in 1911 temperatures in London hit 37.8C (100F):

In those days, London was known as “The Smoke” for good reason. Coal power stations, gas works, steam trains and pretty much all industry filled the atmosphere with fumes, blocking out much of the sun’s energy.

There is nothing unprecedented about the weather in the past week.

Just as significant are the temperatures in more rural areas – 98F (36.7C) at Canterbury, Epsom and Raunds in 1911.

This week, the highest temperature at a Class 1 site was 35.5 at Rothamsted, in the Hertfordshire countryside just outside the London urban heat bubble.

The heatwave in 1911 was also long lasting, extending from July well into September. It was also exceptionally dry.

I’ll do a full analysis when summer is over. But the summer of 1911 disproves the notion that we did not used to have heatwaves like this year’s in the past.

Henrik Svensmark fired by his university

by K.I. Dahl-Madsen,  July 21 ,2026 in Clintel.org

 Something unusual and encouraging has happened in Danish climate journalism. Berlingske, one of Denmark’s leading national daily newspapers, has published an excellent and genuinely inquisitive article about the dismissal of physicist Henrik Svensmark from the Technical University of Denmark (DTU), where he has been working since the late nineties. The headline leaves no room for doubt: “Controversial Danish climate and space researcher has received the pink slip from DTU: It is ‘a death blow’ to my research”.

Here is how the article starts:

He is one of Denmark’s most internationally recognized researchers – and at the same time one of the most controversial. But now space and climate researcher Henrik Svensmark has, in his own words, been “good old-fashioned fired” by his employer, the Technical University of Denmark (DTU) in Lyngby. He does not rule out that “political considerations” – as he puts it – were involved in the years-long process that led to his final dismissal. At the same time, Henrik Svensmark does not hesitate to call it “a death blow” to a branch of research that he has largely developed single-handedly and that climate researchers around the world, including the UN’s climate panel (IPCC), have had to relate to – often reluctantly. This is mainly because Svensmark’s research points to what he sees as an overlooked natural factor behind a large part of the climate changes Earth has undergone. He finally does not rule out that the dismissal may be linked to the fact that he is perceived as a controversial researcher in wide circles: “There is nothing controversial about the research itself. But it is true that many perceive my research as controversial, even though it shouldn’t be.” DTU has no comments on the actual dismissal of Svensmark and refers to it as a personnel matter. However, the director of DTU Space, Henning Skriver, confirms that Svensmark’s overarching research area, atmospheric physics, will now “be significantly down-prioritized.”

Science journalist Lars Henrik Aagaard deserves credit for the whole article. Rather than dismissing Svensmark as merely ‘controversial’, he asks the essential question: is DTU retiring an ageing employee, or is it terminating an internationally recognized but scientifically inconvenient research program?

New Study Details Massive Recent Sea Ice Expansion And Cooling In The Greenland Sea

by K. Richard, Aug 13, 2026 in NoTricksZone 

Scientists (Yilgan and Jónsdóttir, 2026) report annual mean sea ice extent in the Greenland Sea was 8.4 times greater in 2023 (2,403.6 km²) than in 2019 (287.6 km²).

In the month of January, the sea ice extent was 6.4 times larger in 2024 (20,308 km²) than in 2017 (312 km²).

Hand-in-hand with the recent sea ice expansion, the region has experienced a short-term 1°C cooling from 2016 to 2024.

…

The recent trend for the Greenland Sea appears to be consistent with the trajectory enveloping much of the Arctic since the mid-2000s as reported by England et al., 2025.

“Over the past two decades, Arctic sea ice loss has slowed considerably, with no statistically significant decline in September sea ice area since 2005.”

Soon corals may invade all those useless bare patches of sand…

by Jo Nova, Aug 11, 2026 in JoNovaBLog 

The Fact is, after forty years of man made global warming and 1,100 billion tons of CO2 there is better coral cover on the Great Barrier Reef than there was in 1985.

VIDEO in the text, 14min

The ABC hasn’t reported this, so I feel compelled to share the news as a public service. We know if it were “another record low” it would have been the lead story on the 7pm news.

So here we are, yet again — Humans have dumped 1.1 Trillion tons of CO2 into our atmosphere since these comprehensive surveys started and who can tell? That’s over sixty percent of all human CO2 emissions ever, that have been recklessly released since 1985 and there is nothing to show for it in the largest and longest surveys we have of the biggest reef in the world.

“Lucky” the UN didn’t slap an endangerment warning on it isn’t it? Lucky for them.

…

…

Misinformation is a government funded industry

Ten years after the corals hit a record low, the Australian Environment Foundation survey showed that half the country didn’t realize the reef has recovered. Only 3% knew the corals were at a record high, and nearly half the Green voters were as wrong as they possibly could be — they thought coral cover was at a record low.

This mass ignorance is not an accident. The ABC cultivates it. But AIMS, the CSIRO and most of our academics stayed silent when they could have spoken up. All around the world right wing governments are being created that are taking an axe to corrupt programs. Will these self-serving institutions wise up and raise their game in time, or will they sink with the Big Bloated Government Team that they nakedly campaign for?

The UN Green Climate Fund is a wasteful fraud

by D. Wojick, Aug 12, 2026

The UN Green Climate Fund (GCF) is neither Green nor about climate. They are mostly just doing normal foreign aid that the donor countries would be better off doing themselves. They have received and spent over $20 billion to date, with more billions coming.

For example, they fund a lot of water supply systems in dry countries. They call it “climate change adaptation,” but it is not adaptation to climate change. It is addressing a condition that has always existed. It is fraud to call this “climate funding.” The same is true for flood protection in flood-prone areas or improving existing farms, which they also do a lot of.

Moreover, much of this so-called adaptation funding actually increases CO2 emissions, so it is not even green.

A fine example is their biggest funding to date, which is part of the huge Jordan Desalination Project. The GCF says that Jordan is among the world’s driest countries, so it certainly needs water. But Jordan has been this dry throughout its history, so the project has nothing to do with climate change.

Then too, desalination uses lots of electricity, and Jordan’s electric power production is around 70% fossil-fueled, mostly with natural gas. The project includes a token solar facility, but it only covers a small fraction of the 24/7 energy required for desalination and pumping the water up to the users, most of whom are around 1,000 meters higher than the plant.

Cherry-Picking Met Office Drops Declining Wind Speed Chapter From Its Latest Annual Climate Report

by C. Morrison, Aug 12, 2026 in WUWT

Lower UK wind speeds and less powerful storms have always been a bit of a disappointment to activists whipping up a climate crisis frenzy to back the Net Zero fantasy. Going back over 50 years, the data is clear on a declining trend. Of course, despite its lamentable inability to step up to the Net Zero plate, wind is one of the UK’s “essential climate variables”, to quote the Met Office’s own words. Since it first started publishing its annual state of the UK climate report, the climatic performance of wind and storms have had their own dedicated chapter. Alas, no more. The 2025 report, published last month, has abolished the chapter – wind it seems is now little more than a footnote. Should do better, some might comment.

However hard one tries to regard the Met Office as a sound independent science body, its obvious Net Zero promotion constantly gets in the way. “Embarrassingly duped by activists” was Matt Ridley’s recent verdict and it is difficult to disagree. How it can justify abolishing wind is almost beyond comprehension. It doesn’t take a particularly cynical nature to suggest the ever-expanding chapter on temperatures is unlikely to disappear in future editions.

Les catastrophes naturelles, notamment climatiques, sont moins nombreuses

by Ph. Delsol, 11 août 2026 in Contrepoint.org

Nous avions déjà noté qu’après une baisse de 8 % en 2025, les tarifs de la réassurance avaient chuté de plus de 14 % lors des renouvellements du mois de janvier 2026, notamment du fait de sinistres climatiques moins importants. Le premier semestre 2026 confirme la baisse significative de la sinistralité climatique. Les principaux acteurs mondiaux de la réassurance, particulièrement Munich Re et Swiss Re, enregistrent de ce fait des résultats en forte hausse. Et lors des renouvellements des contrats en juillet 2026, les prix de la réassurance ont encore reculé de 5,5% (cf. Les Echos du 10 août 2026).

Néanmoins la gauche qui a fait son fonds de commerce de l’écologie punitive continue d’alimenter un discours catastrophiste. « Les sinistres se multiplient, les coûts explosent » entend-on sur France Culture le 29 juillet. Sur RMC, ce 6 août, Jean-Philippe Dogneton, directeur général de la Macif, considère que nous vivons une « époque qui s’aggrave sur le plan climatique ». Certes, les incendies sont cette année d’une ampleur inédite. Mais il faut moins en accuser le dérèglement climatique que l’impéritie de l’Etat qui, faute de moyens et de volonté, laisse prospérer la criminalité, à laquelle semble-t-il tant de feux sont dus, et s’est révélé incapable de mieux anticiper et notamment d’équiper les corps de pompiers de suffisamment de Canadair, ou équivalents.

Plutôt que de vouloir changer le climat, peut-être faudrait-il apprendre à s’y adapter et à vivre avec la chaleur comme beaucoup de pays le font depuis longtemps.

Defining Temperature

by A. May, Aug 9, 2026 in WUWT

…

 

Local temperature

This is the temperature used in climate and meteorological studies. It is the foundation of heat conduction, and hydrodynamics. One assumes local thermodynamic equilibrium over some volume and measures or assumes a local temperature for the volume. This is the logic used in the famous Navier-Stokes equations. This assumed “local equilibrium” is valid over small volumes (for example an “air parcel”) for short time periods. The problem with some climate models is that they assume “local equilibrium” for volumes and time periods that are too large and too long.

Discussion

Temperature is not a primitive mechanical property like mass; it is an emergent statistical property that characterizes the distribution of energy among degrees of freedom (Landau & Lifshitz, 1980). Mass can be measured independently of the rest of the universe or system and does not change as the system around it changes. Temperature follows from the 0th law of thermodynamics, which says:

If system A is in thermal equilibrium with system B,

and system B is in thermal equilibrium with system C,

then A is in thermal equilibrium with C.

The 0th law establishes that “temperature” is a meaningful physical quantity because thermal equilibrium is transitive. It does not define temperature, but it guarantees that temperature is meaningful and measurable. We often hear that temperature is transitive, but this is only true in laboratory settings or at equilibrium. Outside equilibrium, temperature can lose transitivity and different degrees of freedom can produce different temperatures. Transitivity is the basis of equilibrium temperature, but not all temperature measurements.

In summary, the thermodynamic definition of temperature applies only to equilibrium states, but physics uses many other temperature concepts like kinetic, effective, local, and generalized that are essential for describing real systems far from equilibrium. Restricting “temperature” to its equilibrium definition ignores the vast range of physical systems where temperature is well-defined and indispensable.

IPCC Admits Apocalyptic Climate Scenarios Are “Implausible” – Meaning Most Media Scare Stories Over Last 15 Years Are Officially Junk

by C. Morrison, May 6, 2026 in WUWT

Activist climate scientists, journalists and Net Zero-obsessed politicians are in shock following an official admission from the Intergovernmental Panel on Climate Change (IPCC) that a set of key assumptions promoting a climate ‘crisis’ since 2011 are “implausible”. The notorious set of always-improbable RCP8.5 ‘pathway’ assumptions which fed into computer models trying to measure an unmeasurable climate are no more. Since around 2011, these ‘business as usual’ assumptions have produced outlandish claims of future climate catastrophe which have been lapped up by lap dog journalists and politicians. The influential writer Roger Pielke Jr. called RCP8.5’s demise, “the most significant development in climate research in decades”.

Others might observe that we have not heard the last of RCP8.5. Its gross misuse is likely to be given a starring, central role when the history of the Great Climate and Net Zero Scam comes to be written.

Pielke lays it out clearly what has happened:

What matters today is that the group with official responsibility for developing climate scenarios for the IPCC and broader research community has now admitted that the scenarios that have dominated climate research, assessment and policy during the past two cycles of the IPCC assessment process are implausible. They describe impossible futures.

He goes on to note that tens of thousands of research papers have been and continue to be published using these scenarios. In addition, a similar number of media headlines have “amplified their findings”, while governments and international organisations have built these implausible scenarios into policy and regulation.

Continuing Slump in Global Media Climate Agitprop Bodes Ill for Future Net Zero Support

by C. Morrison,  Apr 13, 2026 in TheDailySceptic

Decades of careful grooming of incurious journalists designed to whip up a non-existent climate emergency have failed to halt a dramatic continuing collapse in mainstream media stories backing the Net Zero fantasy. Last year saw a 14% global slump in climate-related stories compared to 2024, which was already 38% down on peak Greta hysteria in 2021. Perhaps there is only so long that once trusting consumers are prepared to read, let alone pay for identical, narrative-driven drivel that is often so one-sided that it is an insult to the intelligence. Exhibit 1: the BBC’s October 2023 classic – Climate change could make beer taste worse.

The greatest declines over 2025 were found in Africa, the Middle East and North America. Interestingly, the failed Amazon COP30 meeting in November 2025 was followed the month after by coverage falling off a cliff in Latin America (-61%), Oceania (-52%) and the European Union (-41%). A period of private grief seems to have given  the long-suffering public a merciful break from the relentless cacophony of climate catastrophising.

News of the continuing falls in climate change and global warming coverage are contained in the latest annual report from the Media and Climate Change Observatory (MeCCO) at the University of Colorado Boulder. To produce its latest findings, MeCCO tracked the volume of newspaper, wire services, radio and TV climate stories across 59 countries and seven regions. The work is said to have used a consistent methodology since 2004.The graph below shows clearly the spikes in the Greta hysteria around the start of the current decade, and the earlier Gore grift that followed the release of his ‘An Inconvenient Truth’ film.

German Expert: Heat Dome Led To Record Temps In Western USA…Warmer In 1934, 1936

by P. Gosselin, Apr 11, 2026 in NoTricksZone 

Is a Warming of 1.1 Degrees C Unusual?

he cause of the high temperatures around March 20, 2026, was a heat dome, the likes of which occur in the Midwestern United States every few decades. Looking at the temperatures in Phoenix, Arizona, one finds:

    • The 105°F maximum temperature from March 19 to 21 is 5°F above previous maximums for this period, but only 1°F above the 104°F that occurred in early April 1989.

    • The highest temperature ever recorded in Phoenix was 122°F during the heat dome of late June 1990.

      For some days, the record highs are over 100 years old (Jan 18; June 11 and 12; July 2, 3, 6, and 23; Aug 6; Sept 8 and 23). The highest May temperatures were recorded in 1910.

    • The warmest year in Phoenix was 1934, the first year of the Dust Bowl era. Some of the temperature records for several states that still stand today originate from this year and the following two.

  • ….

Conclusion

A heat dome is a weather phenomenon that has led to record temperatures in the Western USA multiple times before. Record temperatures in many U.S. states still date back to the period between 1934 and 1936, even though the urban heat island effect has increased significantly since then and amounts to up to 5°C for Phoenix, Arizona, for example. Media reporting on the heat in March 2026 is alarmist because it fails to mention these facts.

Data Centers, Hot Air, and the Reinvention of the Urban Heat Island

by A. Watts, April 5, 2026 in WUWT

If you have been following the rapid expansion of AI infrastructure, you have probably seen the latest claims that data centers are now creating their own “heat islands” large enough to affect hundreds of millions of people. The narrative comes courtesy of a recent working paper, quickly picked up and amplified by Fortune in: Data centers are so hot their ‘heat island’ effect is raising temperatures up to 6 miles away, which presents the findings in a way that suggests a new and potentially significant environmental driver emerging from the digital economy.

According to the article, researchers examined more than 6,000 data centers worldwide and found that surrounding areas experienced an average land surface temperature increase of about 2°C over the period from 2004 to 2024, with some locations showing increases as high as 9°C. The reported influence extends outward roughly six miles from facilities, and when combined with population maps, the authors estimate that as many as 343 million people could be affected These are large numbers, and presented without context they give the impression of a widespread and growing climate signal tied directly to AI infrastructure.

The underlying paper, however, tells a more nuanced story. The key variable being analyzed is not air temperature in the meteorological sense, but land surface temperature derived from satellite observations. That distinction matters because land surface temperature is extremely sensitive to local surface characteristics. Replace vegetation with buildings, pavement, and industrial equipment, and the measured surface temperature will rise, regardless of whether the underlying atmospheric conditions have changed in any meaningful way.

US Heatwaves Much Worse In Past

P. Homewood, Apr 2, 2026 in NotaLotofPeopleKnowThat

There were a few days of hot weather in the US a couple of weeks ago. Attribution “scientists” immediately jumped up and announced that the heatwave would have been “virtually impossible” without challenge.

It’s the same old, unsubstantiated claim that gets wheeled out every time it gets hot. And every time they ignore the lessons of history.

If heatwaves are caused by global warming, what caused them in the past? Not only have they always occurred, they were considerably more severe in the past in the US.

Anthropogenic aerosols can shape the winter mid-latitude cyclone tracks

by Cao, D. et al., March 18, 2026 in Nature OPEN ACCESS

Abstract

Mid-latitude cyclones are “parent storms” of various weather hazards and contribute significantly to the moisture and heat intrusion into the Arctic. Anthropogenic aerosols are known to affect cyclone intensities and their associated precipitation, but their impacts on cyclone tracks remain largely unclear. Here, based on both observational data diagnosis and global climate model simulations, we show that anthropogenic aerosols over East Asia can lead to a significant poleward drift of mid-latitude cyclone tracks in winter over the North Pacific. By suppressing precipitation in the southeastern sector of cyclones and enhancing it in the northeastern sector, aerosols increase the positive potential vorticity tendency northeast of the cyclones, thereby driving their poleward drift. This might give rise to more cyclones migrating into the Arctic over the North Pacific, reducing the Arctic sea ice extent in recent decades. In the future, efforts to reduce aerosol emissions in East Asia could potentially mitigate the poleward migration of the storm track driven by global warming.

Breakthrough Exposes Volcanic Corruption of Global Temperature Data for 50 Years

by C. Rotter, Apr 1, 2026 in WUWT

A persistent assumption underlies modern global temperature reconstructions: that individual station errors, even when large, are diluted through spatial averaging and homogenization. That assumption deserves closer inspection. Recent analysis of station-level data suggests that under certain conditions—specifically when extreme outliers evade quality control and are subsequently incorporated into homogenization routines—localized anomalies can propagate nonlinearly through the global record.

The present investigation began with a routine audit of tropical station residuals within the GHCN (Global Historical Climatology Network) dataset. The initial objective was unremarkable: quantify the distribution of post-homogenization adjustments across low-latitude stations. What emerged instead was a persistent and statistically anomalous signal centered on a single station in Costa Rica, hereafter designated CR-VOLC-EL-INFIERNO-01.

The anomaly first appears in the late 1970s, coinciding with documented volcanic activity in the Talamanca Range. At face value, elevated temperatures in proximity to geothermal activity are not unexpected. What is unexpected is the magnitude, persistence, and downstream influence of those readings once introduced into the global processing pipeline.

Raw observations from CR-VOLC-EL-INFIERNO-01 indicate sustained daily maximum temperatures exceeding 300°C over multiple reporting intervals. Such values would ordinarily trigger immediate exclusion under standard quality control thresholds. Yet archival flags associated with this station indicate no such exclusion occurred. Instead, the readings were retained and subjected to standard homogenization procedures.

To understand how such values could persist, it is necessary to examine the homogenization framework itself. Modern temperature datasets rely on relative homogenization techniques, wherein each station is adjusted based on comparisons with neighboring stations. The fundamental assumption is that neighboring stations share a common climate signal, allowing discontinuities (instrument changes, relocations) to be corrected through statistical alignment.

New Study Finds Warming Saves Lives…Cold Temperatures 12 Times More Deadly Than Excess Heat

by K. Richard, March 30, 2026 in NoTricksZone 

Because cold temperatures are so much more dangerous to human health than warmth, a modest 0.5°C warming could save over 10,000 lives per year in the US.

A new study indicates that from 2000 to 2020 there were 6,129 annual deaths attributable to excess summer heat across 1,514 US counties (representing 91% of the United States’ adult population).

Heat-related deaths receive the vast majority of media attention due primarily to the assumption that humans can control the temperature of the ocean and surface air by emitting more or less CO2.

However, the real health risk – even in wealthy countries like the US – is not “global warming,” but exposure to cold temperatures in winter.

This same study reveals there were 72,361 deaths per year attributable to exposure to 21st century cold temperatures in the US.

In other words, cold winter temperatures are associated with 12 times more deaths (40.1 deaths per 100,000 person-years) than deaths linked to excessive heat (3.4 deaths per 100,000 person-years).

Because the US has continued to have “extreme winter events” in the 21st century and “unusually cold winter snaps” in the South, the “cold related deaths in the US have increased by 9% per year over the past two decades.”

Non-optimal temperature-related deaths have been increasing, with cold non-optimal temperatures far more deadly.
