The ‘Climate Crisis’ of 1695

by R. Barmby, Nov 03, 2025 in ClimateChangeDispatch 

Centuries-old thermometer records show central England warmed 2°C in 40 years—twice the rate of modern warming.

Thames River Frost Fair
No one would fault you for believing that between 1980 and 2020, we experienced a warming of the climate at a rate that is unprecedented in the last 2,000 years. [some emphasis, links added]

That widespread claim is based on reconstructed (non-thermometer) temperatures up to 1850 and observed (thermometer) temperatures thereafter.

However, sealed thermometer technology predates 1850 by approximately 200 years, and when that data is used, the widespread claim melts away.

Take a close look at the chart below: it is the longest thermometer record in the world, dating back to 1659. The data were compiled by the MET Office, the United Kingdom’s national meteorological service.

With three and a half centuries of instrument data, it transcends being a weather record; it is a climate change record for central England.

The temperature readings were taken on multiple thermometers by many different people, who were probably considered the techies in their day, and none of whom were employed to prove that human influence was warming the planet.

Compare the 40-year temperature trends (black dashed line) of 1695 to 1735 to those of 1980 to 2020.

The warming trend from 1695 to 1735, 2°C over four decades, was double that of 1980 to 2020, at 1°C over four decades.


The earlier warming period was preindustrial—an era whose technology was epitomized by humans circling the globe in wooden sailing ships. Spaceships orbiting the planet, along with heavy manufacturing and prodigious energy production, mark the latter period.

Earlier Englishmen survived from 1695 to 1735, experiencing twice the warming of the last 40 years, and with much less technology.

Had King George II been asked if warming in central England during his reign by 2°C in 40 years was an existential threat to his kingdom, he might reply instead that it was a time of plenty that resulted in English domination.

George II chased Bonny Prince Charles out of Scotland, the French out of North America, and the Spanish around the globe just because they cut off an English naval captain’s ear.

There was no hysteria over the 2°C warming in the early 1700s in Great Britain, even though there were many cultural similarities to today’s global community.

Bill Gates, 893 Companies Ditch Climate Initiative…Call For “Return to Economic Rationality”

by P. Gosselin, Nov 1, 2025 in NoTricksZone 

Nearly 900 companies—including dozens of large international corporations—have quietly withdrawn from the Science Based Targets Initiative (SBTi), reports Blackout News here.

The move is being touted as an “overdue return to economic common sense.”

The SBTi requires its members to set scientifically validated climate targets, essentially aligning their emissions goals with international standards.

The recent exodus of 893 firms signals a growing discontent. According to the reporting, many companies are questioning the practical feasibility of the initiative’s stringent requirements. The core argument?

Political climate policies that ignore technical and financial limitations end up jeopardizing long-term economic viability and weakening global competitiveness, stability and profitability as the bedrock for any meaningful long-term investment.

Great Britain, the USA, and China have seen the highest number of companies ending their participation.

The hundreds of corporate withdrawals mark a pivot toward economic realism and suggests that self-determined, pragmatic strategies are replacing politically mandated ones, asserting that a credible, long-term environmental policy must first respect economic strength.

How Climate Dogma Is Keeping The World’s Poor In The Dark

by P. Keeney, Oct 27, 2025 in ClimateChangeDispatch 

Poverty in India
Among all the discussions about climate change, one aspect of the debate gets far too little attention: the moral and practical costs that climate alarmism places on the developing world. [emphasis, links added]

For those in the West, energy is so plentiful that it’s almost invisible. We flick a switch, start a car, or refrigerate food without considering the miracle of power that makes it all possible.

But for billions of people in Africa, South Asia, and Latin America, energy is not just a convenience in the background; it’s the difference between subsistence and progress, between darkness and light, between education and ignorance.

It is easy for comfortable Westerners to moralize about “ending fossil fuels.” For the world’s poor, that slogan means ending development itself.

Wind and solar can supplement power in modern economies, but they cannot satisfy the needs of industrialization. A solar panel may charge a phone or light a hut, but it cannot operate a factory, a hospital, or a modern water system.

The idea of “leapfrogging” fossil fuels and moving straight to renewables is delusional.

As Danish economist Bjorn Lomborg points out in his book “False Alarm,” a solar panel:

“can provide electricity for a light at night and a cell phone charge, but it cannot deliver enough power for cleaner cooking to reduce indoor air pollution, refrigeration to keep food fresh, or the machinery needed for agriculture and industry to lift people out of poverty.”

For the rural poor in Africa or South Asia, what they need is not less energy but more reliable, affordable, and plentiful energy similar to what the West has long enjoyed.

Yet Western governments and financial institutions have become increasingly obstructive. Under pressure from climate activists, the World Bank and other lenders have reduced fundingfor coal and natural gas projects—the very fuels that helped Western countries prosper.

Wealthy nations, which industrialized through the use of fossil fuels, now refuse the same opportunity to others. It’s a form of moral imperialism: a policy of “Do as we say, not as we did.”

The consequences are significant. In sub-Saharan Africa, around 600 million people still lack electricity. Women cook with wood or dung, inhaling toxic fumes that claim thousands of lives each year.

Bill Gates Retreats From Climate Doom, Tells Activists To Focus On Urgent ‘Social Issues’

by T. Catenacci, Oct 29, 2025 in ClimateChangeDispatch 

Gates, who spent a fortune warning about ‘climate disaster,’ now says it ‘will not be the end of civilization’.

Billionaire philanthropist Bill Gates, who spent tens of millions of dollars funding far-left climate initiatives and authored a book warning of “climate disaster,” is now changing his tune on global warming and urging activists to divert their attention to other progressive causes. [emphasis, links added]

In a lengthy blog post published Tuesday morning, Gates said climate change remains a serious issue, but that “it will not be the end of civilization.”

Gates then bluntly said the money that has been designated for climate is “not being spent on the right things.”

“Sometimes the world acts as if any effort to fight climate change is as worthwhile as any other,” Gates wrote. “As a result, less-effective projects are diverting money and attention from efforts that will have more impact on the human condition: namely, making it affordable to eliminate all greenhouse gas emissions and reducing extreme poverty with improvements in agriculture and health.”

In other words, leaders need to focus less on fighting long-term global warming and more on near-term economic issues.

That means Gates is prepared to divert millions of dollars in funding from climate issues to other social issues, a shift that could have significant reverberations across the American climate-advocacy ecosystem.

U.S Surface Temperature

by WUWT, Oct 2025

August ’25 | 0.54°F (0.30°C)

US Climate Reference Network (Updated when Gov shutdown ends)

Click for description of the data/larger graph

The US Climate Reference Network record from 2005 shows no obvious warming during this period. The graph above is created monthly by NOAA.

The graph shows the Average Surface Temperature Anomaly for the contiguous United States since 2005. The data comes from the U.S. Climate Reference Network (USCRN) which is a properly sited (away from human influences and infrastructure) and state-of-the-art weather network consisting of 114 stations in the USA.

These station locations were chosen to avoid warm biases from Urban Heat Islands (UHI) effects as well as microsite effects as documented in the 2022 report Corrupted Climate Stations: The Official U.S. Surface Temperature Record Remains Fatally Flawed. Unfortunately, NOAA never reports this data in their monthly or yearly “state of the climate report.” And, mainstream media either is entirely unaware of the existence of this data set or has chosen not to report on this U.S. temperature record.

Is Public Criticism of Climate Claims a Criminal Offence in Today’s Britain and Europe?

by E. Worrall, Oct 26, 2025 in WUWT

“… It is perfectly OK to have different opinions on climate change. What becomes problematic is when a society can no longer agree on facts …”

…

…

…

My point is, to declare some facts are beyond challenge, especially “facts” produced by artefacts as flimsy as climate models, is to strike at the foundations of freedom of expression and scientific inquiry. Forcing broadcasters to embrace a uniform, government approved version of unassailable facts, then claiming they still somehow have freedom of expression, is utter nonsense.

Antarctic Amundsen-Scott Station Sees Coldest October in 44 Years…Mainstream Media Silent!

by P. Gosselin, Oct 24, 2025 in NoTricksZone 

This is not supposed to be happening, according to the climate models.

While the headlines relentlessly holler about “exploding global warming” and “dramatic melting” of the polar caps, the South Pole is telling a starkly different story.

Here reports Germany’s Report 24.

On October 15, the Amundsen-Scott South Pole Station registered an astonishing temperature of minus 61.3 degrees Celsius and it isn’t even winter there. It’s springtime and temperatures  should be on the rise.

Coldest October since 1981

According to Report 24, the numbers are clear: It was the coldest October measured at the station since 1981.

This extreme cold is not an isolated event. As the article points out, even CNN reported in 2021 that the continent had experienced its coldest winter since records began.

The data from stations like Amundsen-Scott, Vostok, and Dome C show that instead of a linear, CO₂-driven heating trend, the South Pole is dominated by naturally occurring, extreme temperature fluctuations, including pronounced cold snaps.

Natural factors dominate

This directly contradicts the dominant narrative that “extreme heat is the new normal” and challenges the core assumption that the trace gas CO₂ is the overwhelming, all-determining factor in our climate system. Climatological mechanisms like stratospheric waves, polar vortex stability, and cloud cover appear to be the actual drivers of weather events.

Even growing colder

For decades, we’ve been told that polar regions would experience the strongest warming. Yet, the Antarctic region has stubbornly resisted, in some parts even growing colder.

The Report 24 article argues that this recurring cold record is a “nail in the coffin of the CO₂ dogma.” If carbon dioxide were truly the dominant climate control knob, such an extreme, decades-long cold minimum shouldn’t be happening.

The underlying models—like the IPCC forecasts from the 1990s—have systematically overestimated temperature trends. When faced with such real-world deviations, one must ask: are the climate models flawed, or is the CO₂-centric theory of climate incomplete?

For those politicians and policymakers who are basing sweeping, economy-altering decisions on the idea that the “science is settled,” the stubborn cold of the South Pole presents a critical challenge that can no longer be ignored.

17 Republican AGs Urge Trump Admin To Skip COP30 Over Green Energy Policies

by A. Streb, Oct 24, 2025 in ClimateChangeDispatch 

COP30 Amazon
Seventeen Republican attorneys general urged the Trump administration Thursday to skip the major U.N. climate conference this year over concerns that participation would validate the aggressive green policies that align with the conference’s talking points. [emphasis, links added]

Though the Trump administration has not announced that it will send a delegation to attend COP30 this year, some GOP senators have reportedly floated the idea of participating in the conference on Oct. 10.

The letter, led by West Virginia Attorney General JB McCuskey, warned three energy cabinet secretaries that the administration’s attendance may signal endorsement of COP-aligned green policies that the Republican attorneys general argue have dire consequences.

“Sitting out the COP-30 conference sends a strong message that America will no longer be part of the green new scam. Renewables are not reliable and are expensive – just look at California – but yet, this gathering will continue to push these climate initiatives with their grandiose declarations, while ignoring reality,” McCuskey told the Daily Caller News Foundation. “In this country, we finally have an administration taking bold action to secure the Nation’s energy interests by investing in traditional fuels and undoing harmful regulations. Skipping COP-30 signals that America will pursue energy policies based on what provides the most affordable and reliable energy to the American people, not international pressure.”

Letter Re COP30 From AGs by audreystreb

McCuskey and the 16 other attorneys general argued in the letter that COP-aligned policies like net-zero have major consequences and run counter to the Trump administration’s goals, addressing the warning to Interior Secretary Doug Burgum, Energy Secretary Chris Wright, and Environmental Protection Agency Administrator Lee Zeldin.

New Study Determines It Is ‘Impossible’ For CO2 To Be The Driving Mechanism In Global Warming

by K. Richard,  Oct 24, 2025 in NoTricksZone 

Approximately 75% of the increase in the global ocean heat content must be natural, or attributed to an increase in solar forcing.

The manifestation of what is commonly referred to as “global warming” is predominantly (93%) depicted as an increase in ocean heat content (OHC). Only 1% is indicated by an increase in surface air temperatures. Rising OHC is the parameter of modern warming.

According to Levitus et al. (2012) the 1955-2010 temperature increase corresponding to the rise in OHC amounts to just 0.09°C in the 0-2000 m layer.

A new study calls attention to the abrupt warming and cooling OHC trends since 1955 in this dataset that cannot be attributed to linearly-rising CO2 emissions.

The OHC changes manifest short-term “periods with a very strong +0.8 W/m² (1970-1980) as well as a very strong negative -0.7 W/m² radiation imbalance (1963-1970). But also a period with an almost perfect radiation balance (1980-1990).”

In contrast, the increase in forcing from the gradual rise in CO2 is wholly inconsistent with these dramatic decadal-scale fluctuations.

“[T]he almost constant forcing rate from GHGs [greenhouse gases] cannot have triggered these abrupt radiation imbalance shifts [and therefore] the dramatic radiation balance shifts must have been triggered by natural events.”

It is estimated that ¾ of the rising ocean heat content (OHC) trend since 1955 must be natural, or due to the “rising solar input” associated with the decline in cloud (and aerosol) albedo. In sum, rising CO2 “cannot explain the observed [OHC] trends.”

Net Zero Averted Temperature Increase

by Lindzen et al., June 2024 in CO2Coalition

example, if the United States achieved net zero emissions of carbon dioxide by the year 2050, only a few hundredths of a degree Celsius of warming would be averted. This could barely be detected by our best instruments.  The fundamental reason is that warming by atmospheric carbon dioxide is heavily “saturated,” with each additional ton of atmospheric carbon dioxide producing less warming than the previous ton.

Abstract:

Using feedback-free estimates of the warming by increased atmospheric carbon dioxide (CO2) and observed rates of increase, we estimate that if the United States (U.S.) eliminated net CO2 emissions by the year 2050, this would avert a warming of 0.0084 ◦C (0.015 ◦F), which is below our ability to accurately measure. If the entire world forced net zero CO2 emissions by the year 2050, a warming of only 0.070 ◦C (0.13 ◦F) would be averted. If one assumes that the warming is a factor of 4 larger because of positive feedbacks, as asserted by the Intergovernmental Panel on Climate Change (IPCC), the warming averted by a net zero U.S. policy would still be very small, 0.034 ◦C (0.061 ◦F). For worldwide net zero emissions by 2050 and the 4-times larger IPCC climate sensitivity, the averted warming would be 0.28 ◦C (0.50 ◦F).

The Hill’s Crazy Coral Claims Challenged By Reef Recovery, Record Growth

by L. Lueken, Oct 16, 2025 in ClimateChangeDispatch 

reef coral

A recent article in The Hill, “Climate change is not a ‘con job’,” claims that catastrophic, human-caused climate change is killing reefs via ocean heatwaves. This claim is false. [emphasis, links added]

In reality, corals have existed for millions of years, through warmer and colder periods, and in the recent past, coral reefs have recovered from bleaching events and even die-offs, proving the species is adaptive and resilient in the face of climate change.

The Hill article, from Rebecca Vega Thurber, the director of the UC Santa Barbara Marine Science Institute, is framed by Thurber’s annoyance that President Donald Trump says climate change is a “con job.” She claims her personal research experience refutes his comment.

Thurber explains that pollution from fertilizer runoff can kill corals, which is true, but goes on to assert:

“[E]very result we have collected, in every one of these well-intentioned and carefully designed experiments, was waylaid by the increasingly frequent and severe heat waves that have arisen in the last decades.”

She says their efforts to mitigate pollution were “overwhelmed by high water temperaturesdriven by climate change, or worse, climate change killed our whole experiment.”

Thurber claims marine heat waves in the French South Pacific hampered her work by “transform[ing] these normally bountiful reefs from habitats where there was once 60 percent of the seafloor covered with healthy corals to barren plains with less than 1 percent live coral.”

In point of fact, one long-term study from 2019 showed that rather than a “barren plain,” French Polynesian reefs have an “outstanding rate of coral recovery, with a systematic return to pre-disturbance state within only 5 to 10 years.”

A second study from 2024, published in Nature, sought to understand why reefs bounced backso readily after major heat waves, concluding that:

“Over the past three decades, there have been five main warming events that have caused mass bleaching around Moorea and Tahiti, in 1994, 2002, 2007, 2016, and 2019. Despite bleaching levels up to 100% for some coral species, reefs experienced as high as ~76% recovery following each event. …

“It is currently unknown what controls the ability of coral coverage to recover quickly at these locations. It has been suggested that reefs may develop an increased tolerance to higher SSTs following each bleaching event, and that the increased resilience would allow for a shorter recovery period with less die-off under subsequent SST extremes.”

In short, the scientific literature does not support Thurber’s contention in The Hill that coral reefs are dying off in vast numbers.

We Need to Talk About Climate (To Each Other)

by N. Komar, Oct 1, 2025 in WUWT

Among professionals who work on the climate issue (the “Climate Community”), there is a long-standing reluctance to engage in conversation with people who don’t consider that the climate is in crisis.

Due to this reluctance, there are exceedingly few recorded debates between members of the Community and those from the outside with an appropriate level of expertise to make for a lively and educational dialogue (but there are some, and below, I’ve listed all of the debates that I have been able to find).

I find the lack of debate to be frustrating.  In my case, I am skeptical of the idea that the earth’s climate is in crisis.  To me, the skeptical arguments seem to be more likely to be correct than the alarmist arguments.  Two important reasons for my skepticism: 1) The few actual debates I have had the pleasure to witness have been won by the skeptic(s). 2) The skeptics I speak to appear confident in their views and are eager to debate people from the Community; members of the Community, conversely, display what seems like a tribal attitude and either are hesitant, or in many cases, just unwilling to debate.

I am willing to be proven wrong regarding my skepticism.  But I can’t be bullied into changing my view.  It would take a reasoned argument, juxtaposed against arguments from the skeptic side of the debate.  And I’ve been following this issue for over 25 years.  For the average person curious about climate, but new to the issue, I would guess that it is quite hard to find arguments on both sides in order to make an informed decision for themselves.  While the question of how climate works is a question of Science, the culture that has developed around the issue is a culture of Politics.  Consequently, a search on the internet for articles on climate will return a politically curated batch.

I’ve been working on a project for the last 2-½ years to transform the situation described above.  It’s called Climate Verso.  Currently the project consists of a podcast, with only a few episodes published to date.  It can be found on any podcast platform: https://theclimateversopodcast.buzzsprout.com/

More episodes will be dropping over the next few months, and I’m totally open to help from anyone interested in getting involved.  The format of the podcast is a dialogue between two climate professionals with differing perspectives.  I am the moderator of the discussions.  Please listen to either or both of the episodes published so far. The first is Matthew Wielicki and Peter Fiekowsky debating the efficacy and risks of Ocean Fertilization.  The 2nd is a wide ranging conversation between Judith Curry and Andrew Revkin about how the climate issue became polarized over the last 40 years.

New ‘Climate at a Glance’ Book Challenges ‘Climate Crisis’ Narrative with Hard Data

Second edition of Climate at a Glance, published by The Heartland Institute, provides public with Facts on 40 Climate Topics
First edition in 2022 was a #1 Amazon Best-seller in the categories of ‘Science for Kids, ‘Climatology,’ and ‘Environmental Science’

 

…

“For too long, climate discourse has been dominated by slogans and fear, while real science and sound policy have taken a back seat, but the data tell a far more complicated story. This book is not about denying that the climate changes—it always has and always will—but about questioning whether today’s costly, disruptive policies are grounded in evidence or in politics. By examining the data, the models, and the history of our ever-changing climate, this book cuts through the noise to show that climate change is not a one-way catastrophe but part of Earth’s natural variability. Instead of rushing into policies that wreck economies and livelihoods, we need honest science, open debate, and the courage to question a narrative that too often puts politics before facts.”

Mid-Holocene South China Sea Level 2-3 Meters Higher Than Today Due To 1-2°C Warmer Temps

by K. Richard, Sep 30, 2025 in NoTricksZone 

The mechanisms driving the meters-higher sea levels a few thousand years ago do not support claims that CO2 is a driver.

A comprehensive analysis (Zhang et al., 2025) of the South China Sea region indicates warmer sea water was fundamentally responsible for sea levels that were, on average, 2-3 meters higher (and in some regions as much as 5-7 meters higher) than today from approximately 7000 to 4000 years ago.

“Understanding Holocene high sea levels in the South China Sea (SCS) is critical for understanding climate change and assessing future sea-level rise risks. We provide a comprehensive review of the Holocene highstand in the SCS, focusing on its age, height, and mechanisms. Records reveal a wide range for this highstand: ages span 3480–7500 cal yr BP, while elevations range from −7.40 to 7.53 m relative to the present. Positive elevations dominate (80.5% of records), with the most frequent range being 2–3 m.”

“…the Holocene high sea level in this region occurred between 7200 and 5000 yr BP…at least 2.9-3.8 m higher than today.”

The Amazon’s “CO₂ Problem”? Turns Out the Trees Love It – So Does the Media

by A. Watts, Oct 1, 2025 in WUWT

For decades, we’ve been warned that the Amazon rainforest—the so-called “lungs of the planet”—was on the verge of collapse. Headlines screamed about tipping points, mass die-offs of giant trees, and irreversible climate catastrophe. Yet, buried in the data, something rather inconvenient has been happening: the Amazon is getting bigger, fatter, and taller.

A new Nature Plants study, covering 30 years of field data from 188 permanent forest plots across Amazonia, shows that the average size of Amazon trees has increased by more than 3% per decade . In plain English: the forest isn’t shrinking in stature, it’s bulking up.

The researchers found:

  • Mean tree size up 3.3% per decade
  • Largest trees (>40 cm diameter) increased 6.6% per decade
  • Biomass increasingly concentrated in the biggest trees
  • No evidence of large-scale die-off from climate stress

In their words:

“We find that tree size has been increasing across all size classes… The observed patterns match the expectations from increased resource availability, particularly from rising atmospheric CO₂.”

So much for the “large trees are doomed” hypothesis.

…

…

My Final Thoughts

The real takeaway is this:

  • Rising CO₂ is not just a “pollutant”—it is also a powerful plant fertilizer.
  • Amazonian forests are currently benefitting, not suffering, from this change.
  • Predictions of imminent collapse have once again run headlong into inconvenient data.

When climate modelers assure us that “the science is settled,” it’s worth recalling just how often field data overturns the narrative. The Amazon was supposed to be collapsing. Instead, its trees are thriving.

That doesn’t sell headlines or funding proposals, but it’s what the evidence shows.

So, next time someone calls CO₂ “pollution,” remind them: without it, plants—and by extension, we—wouldn’t exist. And with a bit more of it, the world’s largest rainforest seems to be doing just fine.

Europe: AI Development or Net Zero?

by  S. Goreham, Sep 18, 2025 in CornwallAlliance

This year, European nations announced plans to pursue artificial intelligence. National leaders announced AI spending goals totaling hundreds of billions of euros in efforts to catch up to the United States. But AI requires huge amounts of electrical power, conflicting with Europe’s commitment to achieve a Net Zero power grid.

Since ChatGPT released their AI chatbot in November of 2022, artificial intelligence has exploded. In only two years, the AI revolution became the driving force in the US high-tech industry. Amazon, Google, Meta, Microsoft, and other firms will spend over $100 billion this year building and upgrading data centers to run AI. Nvidia, the dominant supplier of AI graphics processor units (GPUs), became the most valuable company in the world, its market capitalization soaring from $300 billion to $4.3 trillion in less than three years.

Artificial intelligence requires vast amounts of electricity. AI processors run 24 hours a day, enabling computers to think like humans. When servers are upgraded to support AI, they consume 6 to 10 times more power than when used for cloud storage and the internet. Data centers consumed 4% of US power at the start of 2024 but are projected to consume 20% within the next decade.

The need for new generating capacity for AI now drives US electricity markets. Coal-fired power plant closures have been postponed in Georgia, Indiana, Illinois, Tennessee, Utah, West Virginia, and other states. Nuclear plants are restarting in Iowa, Michigan, and Pennsylvania. Dozens of small modular reactors are on the drawing board. More than 200 gas-fired plants are in planning or under construction, including more than 100 in Texas. Companies building AI data centers are constructing their own on-site power plants, unwilling to wait for grid power. The pursuit of artificial intelligence is rapidly replacing obsolete US Net Zero policies.

Lomborg: Environmental Doomsday Predictions Collapse As World Becomes Richer And Greener

by B. Lomborg, Sep 16, 2025 in ClimateChangeDispatch 

Fearmongering climate change forecasts keep falling apart.

Climate protest
Over the past half-century, environmentalists have predicted countless calamities. Their extreme predictions were typically wrong, their draconian countermeasures turned out to be mostly misguided, and we should be grateful we didn’t follow their harmful advice. [emphasis, links added]

We need to keep this history in mind as we are inundated with stories of climate Armageddon.

This summer, headlines about the Great Barrier Reef painted a dire picture of climate-driven devastation, with environmental journalists claiming the reef was on the brink of collapse.

In reality, data shows the reef has its fourth-highest coral cover since records began in 1986, revealing these alarmist narratives to be vastly misleading.

Truth and Scares

Sensible, life-improving environmental policies over recent decades were rarely sold with fearmongering. Rich countries have dramatically reduced air and water pollution through technological advances and then through regulation.

Poorer countries are starting to do the same thing, as they emerge from poverty and can afford to be more environmentally concerned. Forests have expanded globally, with this growth clear in rich countries and increasingly across the world.

This isn’t the scary future environmentalists promised us.

A recent peer-reviewed study counts almost a hundred environmental doomsday predictions that environmentalists have made over the past half-century.

Two-thirds of them predicted doom before August 2025, and all of these have turned out to be false.

UK Poll Shows Rising Climate Skepticism, Opposition to Net-Zero Policies

by O. Wright et al., Sept 12, 2025 in ClimateChangeDispatch 

New research finds a sharp rise in climate change skepticism as Brits reject net-zero policies

Ed Miliband's wind farm fantasy
The number of Britons who think the dangers of global warming have been exaggerated has jumped by more than 50 percent in the past four years, new research for The Times reveals today. [emphasis, links added]

One in four voters now believes that concerns over climate change are not as real as scientists have said, amid growing public concern about the cost of the government’s net-zero policies.

Less than a third of the public (30 percent) are in favor of banning new petrol and diesel cars — down from 51 percent in 2021.


Only 16 percent of voters said they would be prepared to pay higher gas bills to encourage the switch to electricity.

Experts said the findings showed that growing climate skepticism within mainstream politics in both Britain and the US was cutting through with voters, as the broad consensus on climate action breaks down.

“Climate change is being politicised [in the UK] in the same way that has been done in the United States,” said Professor Wouter Poortinga, an environmental psychologist at the University of Cardiff.

Another New Study Suggests Most – 80% – Of The Modern CO2 Increase Has Been Natural

by K. Richard, Aug 29, 2025 in NoTricksZone 

An independent researcher (Robbins, 2025) has reviewed recent research that suggests at least “80% or more of the [modern CO2] increase is of natural origin.”

This is because “changes in atmospheric temperature are an ‘effect’ of changes in SSTs and not a ’cause’ as some might advocate.”

…

…

Similar conclusions are found in a paper published in the same peer-reviewed journal last year (Ato, 2024).

“SST [sea surface temperature] has been the determinant of the annual changes in atmospheric CO2 concentrations and […] anthropogenic emissions have been irrelevant in this process…”

Media Falsely Claim Antarctica On Brink Of Climate Doom, Ignore Contrary Data

by A. Watts, Aug 29, 2025 in ClimateChangeDispatch 

Why abrupt Antarctic ‘climate shifts’ aren’t new or necessarily catastrophic.

 

Emperor Penguins
A recent CBS News article, “Abrupt Antarctic climate shifts could lead to ‘catastrophic consequences for generations,’ experts warn,” claims that Antarctica is on the brink of irreversible collapse due to climate change, warning that sea levels could rise by meters and that “catastrophic consequences for generations” are looming. [emphasis, links added]

This is false or, at best, deeply misleading.

The actual data and history of Antarctic ice show that “abrupt changes” are neither unprecedented nor a reason to panic. Natural variability and cyclical shifts are being ignored in favor of sensational headlines pushing the increasingly untenable climate crisis narrative.

CBS was not alone in pushing the Antarctic climate crisis narrative.

On August 21, 2025, the Australian Broadcasting Corporation (ABC) joined the chorus of media outlets with alarming headlines warning of a pending ice collapse, publishing a report claiming Antarctica is undergoing “rapid, self-perpetuating changes” that are “potentially irreversible.”

Each of the reports cited a new Nature review led by Professor Nerilie Abram as the source of the information for their alarming articles.

ABC’s article presents Antarctica as being in a state of runaway decline, with imminent threats to emperor penguins and global sea levels, parroting language from the Abram paper as if it were an observed fact, rather than the speculative synthesis of research papers that the Nature study cites.

CBS, ABC, and other media outlets are covering this story as if a tipping point is upon us—but a closer look at the evidence reveals otherwise.

NYT Falsely Blames Climate Change For Hurricane Erin Despite No Evidence

by L. Lueken, Aug 28, 2025 in ClimateChangeDispatch

Rapid intensification of Hurricane Erin isn’t unusual, and attribution studies don’t prove climate change caused it.

The New York Times (NYT) published an article titled “How Climate Change Affects Hurricanes Like Erin,” in which they rely on rapid attribution analysis to claim that climate change is making rapidly intensifying hurricanes more likely, implying that the storm was worsened by global warming. This is false. [emphasis, links added]

Attribution studies are generally not based on solid scientific evidence and, therefore, not provable. Plus, there is a lack of evidence to support the notion that rapid intensification is becoming more common.

At the outset, the NYT claimed that hurricane Erin’s effects, such as they are, “are made worse by global warming,” even though the storm stayed offshore. The storm intensified quickly from a Category 1 to a Category 5 hurricane, and NYT claims that “[a]s the planet warms, scientists say that rapidly intensifying hurricanes are becoming ever more likely.”

First, it is important to note that just because a storm is among the most rapidly intensifying on record, it does not mean that there were not similar storms that went unrecorded.

As mentioned in a previous Climate Realism post about hurricane Erin, hurricane measurement technology is far advanced today than it was even a few decades ago.

Before the widespread use of Hurricane Hunter flights starting in the 70s where offshore storms were first closely monitored and directly measured throughout their lifespan, other rapidly intensifying storms would not have made the record.

So there is uncertainty about the record there.

Beyond that, attribution researchers and the NYT would like to blame hurricane intensification all on warm sea surface temperatures, but rapid intensification occurs in response to a variety of factors lining up just right.

Similar claims were made two years ago concerning Hurricane Otis. That storm also intensified rapidly over a single day, turning into a Category 5 before hitting the west coast of Mexico.

Otis did not intensify under expected conditions; thunderstorm bursts that forecasters were unable to predict are now believed to have been responsible for its rapid intensification.

Just as some scientists say more intense storms are more likely with warming, other scientists say that they will become less likely to form or less likely to strike land.

The NYT neglected to mention these perspectives, focusing its story on the scarier opinions that support the narrative that climate change is responsible for worsening extreme weather events.

In fact, as Climate at A Glance: Hurricanes details, there is no data suggesting hurricanes are becoming more frequent or more intense.

Study Finds Extreme Weather Database Exaggerates Global Disaster Trends

by Climate Discussion Nexus, Aug 28, 2025 in ClimateChangeDispatch 

Disasters don’t count if you don’t count them.

City flood aftermath
According to its publishers, a dataset called EM-DAT, which stands for Emergency Events Database, so it’s not even an acronym, lists “data on the occurrence and impacts of over 26,000 mass disasters worldwide from 1900 to the present day.” [emphasis, links added]

Which makes it perfect for studying long-term trends. And what’s even better, for the climate change crowd anyway, is that, as the authors of a 2024 study noted, “There are very strong upward trends in the number of reported disasters.”

But as the same authors noted in the very next sentence, “However, we show that these trends are strongly biased by progressively improving reporting.” Simply put, before 2000, reporting of small disasters that caused fewer than 100 deaths was hit-and-miss.

So, historically, the record of giant disasters that killed hundreds or more persons is reasonably complete, but not the record of small ones.

And the authors of the recent study argue that once they adjust for the effect of underreporting, the trends in disaster-related mortality go away.

The paper, “Incompleteness of natural disaster data and its implications on the interpretation of trends,” by a group of scientists in Sweden, began by noting that they are not the first to point out the problem.

The weird thing is that many authors who have pointed out this massive flaw have then gone ahead and used the data anyway, as though it did not exist, or at least they had not noticed it:

“Various authors (Field et al., 2012; Gall et al., 2009; Hoeppe, 2016; Pielke, 2021) have noted that there are reporting deficiencies in the EM-DAT data that may affect trends then proceeded to present trend analyses based on it without correction. Even the EM-DAT operators themselves discourage using EM-DAT data from before 2000 for trend analysis (Guha-Sapir (2023)). Yet recently, Jones et al. (2022) investigated the 20 most cited empirical studies utilising EM-DAT as the primary or secondary data source, and found that with only one exception the mention of data incompleteness was limited to a couple of sentences, if mentioned at all.”

Having made that point, their study then digs into the records and shows that in the post-2000 period, there is a steady pattern relating the frequency of events to the number of fatalities (F) per event.

It follows something that statisticians call “power-law behaviour” in which the more extreme an outcome, the rarer it is, not in a straight line but in an inverse exponential relationship, where extreme things, [like] large numbers of fatalities in a disaster, are a lot rarer than small numbers on a logarithmic curve. (For instance, in boating accidents, there are tens of thousands of individuals falling out and drowning for every Titanic.)

Hydrological, meteorological, and geophysical disasters all follow power-law behaviour in recent decades. But in earlier decades, the relationship doesn’t appear to hold because of a deficiency of low-fatality disasters in the data, rather than because it wasn’t still true then..

Finally, an Unbiased and Objective Climate Science Report

by T. Gallaudet, Aug 26, 2025 in TheEpochTimes

The recent report released by Energy Secretary Chris Wright on the climate impacts of greenhouse gas (GHG) emissions in the U.S. has caused quite a stir in the climate science arena. “Outrage,” “pushback,” and “criticized” are the words used in many of the headlines about it.
To better gauge the overall opinion of the report, two journalists from the Associated Press asked members of the climate science committee if they believed that it accurately portrayed the current “mainstream view of climate science.”

The Medieval Warm Period: A Global Phenomenon?

by M. Wielicki, Mar 06, 2025 in IrrationalFear

The debate over the characteristics and impact of the Medieval Warm Period (MWP), roughly dated from 950 to 1250 AD, lies at the heart of discussions on historical climate variability and its implications for understanding current climate change.

Following the publication of the Intergovernmental Panel on Climate Change (IPCC)Third Assessment Report in 2001, the MWP was essentially erased from the paleoclimatological record in favor of the ‘hockey stick’ graph. This disappearance remains a point of contention that has been particularly prominent in public and scientific debate.

The ‘hockey stick’ graph, first published by Michael Mann, Raymond Bradley, and Malcolm Hughes in 1999, depicted temperature anomalies over the past millennium. It showed relatively minor temperature fluctuations for most of the last millennium (the “shaft” of the hockey stick) and a sharp rise in temperatures in the 20th century (the “blade” of the hockey stick). This presentation suggested that the modern warming period has been unprecedented over the last millennium. This finding has been at the core of calls for robust measures aimed at addressing climate change.
