Climate Scientists Admit Climate Models Exaggerated Warming


Last week, a group of scientists sent shockwaves through the climate science community. They boldly pointed out that current climate models exaggerate greenhouse warming.

In other words, they confirmed what climate skeptics have been arguing all along: that most computer climate models forecast unrealistic warming — warming not observed anywhere in the real world.

Could this be a turning point for climate science? Has the hitherto staunch resistance to any kind of scrutiny regarding the dangerous warming narrative come to an end?

Scientific Method

Science is not a body of facts. It is a method of finding facts — a method that is inherently skeptical. Not cynically skeptical, but humbly skeptical.

It insists, as the motto of the Royal Society, nullius in verba, roughly translated “take nobody’s word for it,” that a scientist’s every claim be tested — over and over and over.

Thus, as the philosopher of science Robert K. Merton put it in 1938, “Most institutions demand unqualified faith; but the institution of science makes skepticism a virtue.”

A scientific hypothesis is carefully studied and checked against the available evidence. The process of establishing a scientific truth involves the scientific community’s continuous effort to falsify it until so many such efforts have failed that the community provisionally accepts it — with emphasis on provisionally.

In the age of celebrity culture, though, people easily assume that theories celebrated scientists — or large numbers of scientists, or scientists associated with government authorities — embrace is above challenge.

Yet even theories universally embraced (for example, that continents don’t move, or that all ulcers are caused by excess stomach acid arising from too-acidic foods or anxiety) are not immune from new challenges or improvements and have been discarded.

Even the most celebrated scientists have been wrong. As EarthSky editor Deborah Byrd notes,

Einstein’s [General] Theory of Relativity implied that the universe must either be expanding or contracting. But Einstein himself rejected this notion in favor of the accepted idea that the universe was stationary and had always existed. When [Edwin] Hubble presented his evidence [the red shift] of the expansion of the universe, Einstein embraced the idea. He called his adherence to the old idea “my greatest blunder.”

It is now understood that the universe is constantly expanding.

Today, climate science finds itself in turmoil. Theories of catastrophic global warming driven by carbon dioxide emissions have long escaped careful scrutiny — just as the theories of acid-caused ulcers and stable continents long did.

Climate Scientists: Yes, the Models are Wrong

Some climate scientists, like Roy W. Spencer and Judith Curry, point out that many warming theories depend on computer models that are badly flawed.

If the empirical, observational evidence — which Nobel Prize-winning physicist Richard Feynman called “the key to science” — doesn’t keep these theories standing, what does?

It appears that it’s the veneer of authority embodied in the United Nations’ Intergovernmental Panel on Climate Change (IPCC).

However, now scientists deeply embedded in the IPCC have admitted that the models exaggerate warming. They raise concerns about the implausibility of the exaggerated warming levels.

Science noted, “But as climate scientists face this alarming reality, the climate models that help them project the future have grown a little too alarmist. Many of the world’s leading models are now projecting warming rates that most scientists, including the modelmakers themselves, believe are implausibly fast.”

These new admissions reaffirm findings in 2014 and 2019 that most models exaggerate warming — though the evidence is that they exaggerate not “a little” but a lot.

Scientists identified these unrealistic exaggerations by comparing model performance with real-world temperature data.

A study published in 2020 analyzed 38 Coupled Model Intercomparison Project Version 6 (CMIP6) models and concluded, “For lower-troposphere and mid-troposphere layers both globally and in the tropics, all 38 models overpredict warming in every target observational analog, in most cases significantly so, and the average differences between models and observations are statistically significant.”

Thus, solid empirical evidence shows that belief in dangerous greenhouse warming is unwarranted, based on faulty computer climate models.

That scientists working within the IPCC now acknowledge these models’ errors could be the first step for climate science’s return to normalcy — that is, to the skepticism that is a hallmark of science — after decades of adherence to the doomsday narrative.

But there are obstacles in the way.

The same Science article that reported the IPCC scientists’ admission that the models run hot also quoted NASA Goddard Institute for Space Studies Director Gavin Schmidt as saying, “It’s become clear over the last year or so that we can’t avoid this” — a slip that suggests that he and others have, contrary to the skepticism inherent in genuine science, been trying to avoid it for a long time.

So long as that mentality prevails, “climate science” will fall short of the true measure of science: honest, humble self-skepticism.

It remains to be seen how the UN will approach this complex and delicate matter. Bold, outright admission could deflate public trust and so undermine the agenda of global “decarbonization.”

Nevertheless, the admission gives hope to climate science’s future. Far too many scientists have been afraidto test climate doomsday narratives. This might give them courage.

Honest scientists follow the evidence wherever it leads. But to stand up and own the truth, scientists must also be freed from political pressure.

Funding for the climate science community flows largely through entities that seek to gain politically from climate fear. This must stop, and academic institutions must no longer function as public relations agencies for fearmongering political narratives.

  1. So with two ‘scams’ (Covid, Climate) exposed to the light and found to be false, what will be the next big thing the ‘Elites’ (via the UN) will try?

    Agenda 21 and Agenda 30 are still going, but they aren’t ‘spectacular-enough, so on that basis, expect another ‘All singing, all dancing’ (And carefully-crafted) crisis to appear ‘Magically’ and out of nowhere. accompanied by the usual (and pre-planned) media ‘excitement’…

    …And for the sheeple to be suitably impressed.



    • It is a scam of monumental proportions.
      NZ has adopted an ETS that has turned the tradeable economy on its head.
      Apparently it is more desirable and profitable to buy land and let it revert to scrub and in the fullness of time become a forest that can never be harvested.
      This Government subsidised madness has enabled all sorts of “ Carbon credit “ scams some to the degree where bare grasslands are being included as credit producers ,because they may ,if appropriately destocked and neglected ,in the fullness of time may produce credits.
      NZ s abysmal productivity record is being subsidised.
      Those who don’t look after their land are making much more money than those enduring the bullying of today’s regulatory regimes.
      Farmers have been going through hell trying to produce and now it is more profitable to do nothing.

      New Zealand must face this disaster now, before it is too late



      • Spot on Falcon.
        Every points to the subsidies like wool, lamb, but that was pretty well stripped 40 years ago.

        Now the rest have been demanding subsidies, like through rates on farmland for feelz good projects in the urban towns.
        Creative Arts are an oxymoron as they demand money to fuel the luvvy duvvies.
        Media, Radio, Papers, Television all get their slice of tax payers money, that is demanded with menaces.
