Science Yields Surprises! Island Nations Growing… “Atoll, Island Stability Is Global Trend”!

by P. Gosselin, Mar 8, 2023 in WUWT

IPCC high-end sea level predictions for 2100 are “highly erroneous”. 

Global warming alarmists like to claim that Pacific island nations are on the verge of disappearing – due to rising sea levels caused by polar ice melting due to global warming, which in turn supposedly is caused by rising concentrations of “heat-trapping” trace gas CO2 from the burning of fossil fuels.

These coral reef island nations risk going under real soon, unless we wean ourselves from fossil fuels soon, they say.

Coral reef island nations are emerging, not disappearing

But yesterday Kenneth here presented a new paper appearing in Nature, (Kench et al., 2023), which looks at whether the coral reef islands are in fact seeing unprecedented and undergoing accelerating physical changes that risk outrunning human adaptation measures. The authors analyzed the dynamics of a Maldivian reef island at millennial to decadal timescales.

Recent changes not unprecedented

The researchers found that “island change over the past half-century (±40 m movement) is not unprecedented compared with paleo-dynamic evidence”.

Nothing unusual is happening. The global data suggest that almost all islands are in fact growing, and not  disappearing under water like climate alarmists mistakenly believe.

“Recent shoreline changes (±40 m/50 years) are ‘dwarfed’ by the shoreline changes (±200 m/100 years) that occurred throughout previous centuries,” the study’s authors write.

 89% of all the globe’s islands are stable, or growing!

Moreover, just 4 years ago, another peer-reviewed publication appearing in a renowned journal found similar results: 89% of the globe’s islands and 100% of large islands have stable or growing coasts! According to Duvat, 2019:

“88.6% of islands were either stable or increased in area, while only 11.4% contracted. It is noteworthy that no island larger than 10 ha decreased in size. These results show that atoll and island areal stability is a global trend, whatever the rate of sea-level rise.”

Moreover, Khan et al (2018) found: “Prediction of 4–6.6 ft sea level rise in the next 91 years between 2009 and 2100 is highly erroneous.”

The new study uses computer models to assess Atlantic storms going back to 1949, and to peer into the future to see what storms will look like in 2100. The authors, climate scientists at Princeton University, found that the flood and wind risk posed by storms has steadily increased.

The problem will only get worse in the coming decades. “The frequency of intense storms will increase,” explains Ning Lin, a climate scientist at Princeton University and the lead author of the new study.

Paul Ehrlich And The Madness Of Climate Alarmists

by J.  Woudhuysen, Jan 12, 2023 in ClimateChangeDispatch

All forecasters make mistakes. But few forecasters have been as consistently wrong as biologist Paul Ehrlich.

So it was quite surprising to see, on January 1, the once venerable CBS series, 60 Minutes, inviting Ehrlich on the show to give his take on the state of the planet.

Focussing on ‘the vanishing wild’, the interview was essentially a forecast of doom, with Ehrlich warning that Earth is in the midst of a ‘sixth mass extinction’ and that its wildlife is ‘running out of places to live’. [emphasis, links added]

Ehrlich, a Stanford University entomologist, is most infamous for his 1968 doom-mongering tome, The Population Bomb.

In the tradition of Thomas Malthus, the prologue begins with the following warning:

‘The battle to feed all of humanity is over. In the 1970s and 1980s, hundreds of millions of people will starve to death in spite of any crash programs embarked upon now. At this late date, nothing can prevent a substantial increase in the world death rate.’

In reality, since The Population Bomb was published, rates of starvation have fallen off a cliff, while the world’s population has doubled.

Ronald Bailey, the science correspondent at Reason magazine, notes that the global crude death rate (deaths per 1,000 people) fell ‘from 12.5 in 1968 to seven in 2019, before ticking up to eight in the pandemic year of 2020’.

Ehrlich has been prolific in promoting mistaken forecasts. With Richard L Harriman, he also wrote How To Be a Survivor: A Plan to Save Spaceship Earth (1971).

Then, with his wife Anne, he issued more lurid warnings in books including Extinction: The Causes and Consequences of the Disappearance of Species (1981) and The Population Explosion (1991).

New Study: Observational Data Affirm 95% Of Post-1970s Warming Is Not Linked To CO2 Increases

by K. Richard, Dec 8, 2022 in NoTricksZone

Of the warming trends in Poland and greater Europe, “only about 4–5% are explained by an increase in CO2 concentration.”  –  Marsz et al., 2022 

Internal changes to the thermal structure of the ocean transmit decadal-scale changes in the atmospheric circulation and consequent surface air temperature via its modulating impact on the variation in the amount and intensity of solar radiation (sunshine duration, or SD) reaching the Earth’s surface.

This is not only observed for Poland and/or Europe as detailed in a new study, but the causal structuring of cloud cover changes driving the variations in solar radiation reaching the surface and modulating climate can be applied throughout the globe ( Wang et al., 2002, Wielicki et al., 2002, Loeb et al., 2021, Herman et al., 2013, Poprovsky, 2019, Dübal and Vahrenholt, 2021, Swift, 2018, Stephens et al., 2022).

Therefore, “the main cause of the change in the state of the climate may be the action of the internal variability of the ocean–atmosphere system” (Marsz et al., 2022).

MIT Climate Scientist Dr. Richard Lindzen Rejects ‘Climate Change’ As ‘A Quasi-Religious Movement Predicated on An Absurd ‘Scientific’ Narrative’

by R. Lindzen, Dec 5, 2022 in WUWT

Dr. Richard Lindzen’s new paper: An Assessment of the Conventional Global Warming Narrative – Published by the Global Warming Policy Foundation – September 22, 2022: Climate change is “a quasi-religious movement predicated on an absurd ‘scientific’ narrative. The policies invoked on behalf of this movement have led to the US hobbling its energy system.” – “The Earth’s climate has, indeed, undergone major variations, but these offer no evidence of a causal role for CO₂.”

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

CO₂ is a particularly ridiculous choice for a ‘pollutant.’ Its primary role is as a fertiliser for plant life. Currently, almost all plants are starved of CO₂. Moreover, if we were to remove a bit more than 60% of current CO₂, the consequences would be dire: namely death by starvation for all animal life. It would not likely lead to a particularly cold world since such a reduction would only amount to a couple of percent change in the radiative budget. After all, a 30% reduction of solar radiation about 2.5 billion years ago did not lead to an Earth much colder than it is today, as we earlier noted in connection with the Early Faint Sun Paradox.

…

The Earth’s climate has, indeed, undergone major variations, but these offer no evidence of a causal role for CO₂. For the glaciation cycles of the past 700 thousand years, the proxy data from the Vostok ice cores shows that cooling precedes decreases in CO₂ despite the very coarse temporal resolution (Jouzel et al.,1987, Gore, 2006). Higher temporal resolution is needed to show that warming preceded the increase in CO₂ as well (Caillon et al, 2003). For earlier variations, there is no suggestion of any correlation with carbon dioxide at all, as shown in Figure 9a, a commonly presented reconstruction of CO₂ levels and ‘temperature’ for the past 600 million years or so.

New Study Finds Australian Sea Temperatures Multiple Degrees Warmer Than Today During The Last Glacial

by K. Richard, Nov 17, 2022 in NoTricksZone

Sea temperatures in regions near Australia have failed to cooperate with a CO2-driven climate narrative.

Glacial conditions and ~200 ppm CO2 levels were thought to have prevailed throughout most of the last 60,000 years across the Earth.

But a new study finds sea temperatures near Australia were “3 to 5°C warmer than the modern average temperature” during several millennia of this period.

Proxy evidence suggests average subsurface water temperatures in the Southern Ocean/Australia region may have been “>7°C warmer than modern” during the last 10,000 years (the Holocene).

The eastern and western core graphical record indicates the amplitude of sea surface temperature swings reached 5 to 7°C from 30,000 to 60,000 years ago – a time when CO2 levels were thought to be stable and low (near 200 ppm).

These records once again affirm sea surface and subsurface temperature changes do not align with the narrative suggesting Earth’s climate changes are driven by fluctuations in CO2 concentrations.

Climate models fail to capture strengthening wintertime North Atlantic jet and impacts on Europe

by Blackport P. & Fyfe, J.C., Nov 11, 2022 in ScienceAdvances

Abstract

Projections of wintertime surface climate over Europe depend on reliable simulations of the North Atlantic atmospheric circulation from climate models. However, it is unclear whether these models capture the long-term observed trends in the North Atlantic circulation. Here, we show that over the period from 1951 to 2020, the wintertime North Atlantic jet has strengthened, while model trends are, on average, only very weakly positive. The observed strengthening is greater than in any one of the 303 simulations from 44 climate models considered in our study. This divergence between models and observations is now much more apparent because of a very strong jet observed over the past decade. The models similarly have difficulty capturing the observed precipitation trends over Europe. Our results suggest that projections of winter atmospheric circulation and associated precipitation over Europe may be unreliable because they fail to capture the response to human emissions or underestimate the magnitude of multidecadal-to-centennial time scale internal variability.

Glacier saga

by J. Curry, Nov 10, 2022 in ClimateEtc.

The loss of glaciers from Glacier National Park is one of the most visible manifestations of climate change in the U.S.  Signs were posted all around the park, proclaiming that the glaciers would be gone by 2020.  In 2017, the Park started taking these signs down.  What happened, beyond the obvious fact that the glaciers hadn’t disappeared by 2020?

Screen Shot 2022-11-10 at 11.31.49 AM

Not only are Montana’s glaciers an important icon for global warming (e.g. Al Gore’s Inconvenient Truth), it also seems that the glaciers are an important political icon for progressive politicians in Montana. Earlier this week, Reilly Neill, a (sort of) politician in Montana, went after me on Twitter:

How IPCC’s 1990 Predictions Expensively Failed

by C. Monckton of Brenchley, Nov 8, 2022 in WUWT

It is now almost a third of a century since 1990, when IPCC made its first predictions about the weather. Since IPCC (2021) continues to predict the same 3 C° midrange long-term warming (equilibrium doubled-CO2 sensitivity, or ECS, broadly equivalent to 20th-century anthropogenic warming from all sources) as in 1990, it is high time someone examined IPCC’s medium-term predictions to shed light on the plausibility of its long-term predictions.

IPCC’s key medium-term prediction in 1990 was as follows –

“Based on current model results, we predict:

  • “under the IPCC Business-as-Usual (Scenario A) emissions of greenhouse gases, a rate of increase of global mean temperature during the next century of about 0.3 C° per decade (with an uncertainty range of 0.2 C° to 0.5 C° per decade). This is greater than that seen over the past 10,000 years. This will result in a likely increase in global mean temperature of about 1 C° above the present value by 2025 and 3 C° before the end of the next century. The rise will not be steady because of the influence of other factors.”

IPCC also predicted as follows –

This second business-as-usual prediction was that there would be 1.8 C° warming from preindustrial times to 2030. Deducting the 0.45 C° warming up to 1990, the prediction amounted to 1.35 C° or about 0.34 C°/decade. Thus, IPCC predicted 0.3-0.34 C°/decade medium-term warming. However, only 0.14 C°/decade has occurred since 1990

Let’s Talk About Real Climate Cataclysms

by P. Driessen, Oct 26, 2022 in ClimateChangeDispatch

The climate crisis! Save our planet! Stop using fossil fuels! The ranting never ends.

Present data show that hurricane frequency and intensity are not increasing, and tornado activity has declined significantly since 1975.

Offer clear evidence of past, recurring major climate changes, including a widespread Little Ice Age from 1300 to 1850, a 2,400-year-old forest emerging from beneath a melting Alaskan glacier, a 5,200-year-old mummified traveler frozen on a once-nearly-ice-free Italian Alps trail – and they respond, Shut up! The climate crisis! The science is settled! Stop using fossil fuels! [bold, links added]

Fine. But take a few minutes to ponder REAL climate disasters: the Pleistocene Ice Ages.

And then ask Michael Mann, Al Gore, John Kerry, and the rest of the climate cataclysm cabal to explain exactly how carbon dioxide and a few other greenhouse gases caused those massive ice sheets to grow and melt, multiple times. Just CO2 and GHG, all by themselves. They can’t do it. The CO2-driven crisis is a fable.

Widespread glaciation began some 1,800,000 years ago in North America and Europe, and about 800,000 years earlier on other continents. There were at least four, possibly five, major glacial periods, interspersed with warm intervals (like the one we’re in now) during which the glaciers mostly melted.

That last glacial epoch is named the Wisconsinan because some of the most exemplary features are in my home state. It marks the furthest extent of glaciers southward into the United States and east and west across Canada.

50-Year U.S. Summer Temperature Trends: ALL 36 Climate Models Are Too Warm

by Dr Roy Spencer, Oct 20, 2022 in GloablWarming

I’ll get right to the results, which are pretty straightforward.

As seen in the accompanying plot, 50-year (1973-2022) summer (June/July/August) temperature trends for the contiguous 48 U.S. states from 36 CMIP-6 climate model experiments average nearly twice the warming rate as observed by the NOAA climate division dataset.

 

The 36 models are those catalogued at the KNMI Climate Explorer website, using Tas (surface air temperature), one member per model, for the ssp245 radiative forcing scenario. (The website says there are 40 models, but I found that four of the models have double entries). The surface temperature observations come from NOAA/NCEI.

The official NOAA observations produce a 50-year summer temperature trend of +0.26 C/decade for the U.S., while the model trends range from +0.28 to +0.71 C/decade.

As a check on the observations, I took the 18 UTC daily measurements from 497 ASOS and AWOS stations in the Global Hourly Integrated Surface Database (mostly independent from the official homogenized NOAA data) and computed similar trends for each station separately. I then took the median of all reported trends from within each of the 48 states, and did a 48-state area-weighted temperature trend from those 48 median values, after which I also got +0.26 C/decade. (Note that this could be an overestimate if increasing urban heat island effects have spuriously influenced trends over the last 50 years, and I have not made any adjustment for that).

The importance of this finding should be obvious: Given that U.S. energy policy depends upon the predictions from these models, their tendency to produce too much warming (and likely also warming-associated climate change) should be factored into energy policy planning. I doubt that it is, given the climate change exaggerations routinely promoted by environment groups, anti-oil advocates, the media, politicians, and most government agencies

Satellite Temperature Data Show Almost All Climate Model Forecasts Over the Last 40 Years Were Wrong

by C. Morrison, Oct 8, 2022 in DailySceptic

A major survey into the accuracy of climate models has found that almost all the past temperature forecasts between 1980-2021 were excessive compared with accurate satellite measurements. The findings were recently published by Professor Nicola Scafetta, a physicist from the University of Naples. He attributes the inaccuracies to a limited understanding of Equilibrium Climate Sensitivity (ECS), the number of degrees centigrade the Earth’s temperature will rise with a doubling of carbon dioxide.

Scientists have spent decades trying to find an accurate ECS number, to no avail. Current estimates range from 0.5°C to around 6-7°C. Without knowing this vital figure, the so-called ‘settled’ science narrative around human-caused climate change remains a largely political invention, not a credible scientific proposition. Professor Scafetta has conducted extensive work into climate models and is a long-time critic of their results and forecasts. In a previous work, he said many of the climate models should be “dismissed and not used by policymakers”. Along with around 250 professors, he is a signatory to the World Climate Declaration which states there is no climate emergency and also notes climate models are “not remotely plausible as global tools”.

Scafetta’s latest work grouped 38 major climate models into low, medium and high ECS values, ranging between 1.8°C and 5.7°C. He found that models in the medium and high category “ran hot” in over 95% and 97% of cases respectively. The lower models were said to have done better when compared to global warming calculated for the period by the major surface datasets of 0.52-0.58°C. But the UAH satellite data showed warming up to 30% less during this period, suggesting even the low warming models produced “excessive warming” from 1980-2021.

According to Scafetta, these results are showed that the ECS figure could be as low as 1.2-2°C. Particular concern is expressed about surface temperature records that “appear to be severely affected by non-climatic warming biases”. Scafetta concludes that surface-based temperature records are likely to be affected by warming biases, such as the urban heat island effect due to expanding urban development, and subject to natural oscillations that are not reproduced by climate models. He concludes: “The global warming expected for the next few decades may be even more moderate than predicted by the low ECS-GCMs [Global Circulation Models], and could easily fall within a safe temperature range where climate adaptation policies will suffice.”

The Media Are Deliberately Lying About Climate Change And Hurricanes

by M. Schellenberg, Oct 4, 2022 in ClimateChangeDispatch

Over the last several weeks, many mainstream news media outlets have claimed that hurricanes are becoming more expensive, more frequent, and more intense because of climate change. [bold, links added]

• The Financial Timesreported that “hurricane frequency is on the rise.”

• The New York Timesclaimed, “strong storms are becoming more common in the Atlantic Ocean.”

• The Washington Postsaid, “climate change is rapidly fueling super hurricanes.”

• ABC Newsdeclared, “Here’s how climate change intensifies hurricanes.”

• Both the FT and NY Times showed graphs purporting to show rising hurricane frequency using data from the U.S. government’s National Oceanic and Atmospheric Administration (NOAA).

All those claims are false.

The increasing cost of hurricane damage can be explained entirely by more people and more property in harm’s way. Consider how much more developed Miami Beach is today compared to a century ago. Once you adjust for rising wealth, there is no trend of increasing damage.

Claims that hurricanes are becoming more frequent are similarly wrong.

“After adjusting for a likely undercount of hurricanes in the pre-satellite era,” writes NOAA, “there is essentially no long-term trend in hurricane counts. The evidence for an upward trend is even weaker if we look at U.S. landfalling hurricanes, which even show a slight negative trend beginning from 1900 or from the late 1800s.”

What’s more, NOAA expects a 25% decline in hurricane frequency in the future.

Weather Disasters Wrongly Linked To Global Warming By Two International Agencies

by P. Homewood, Oct 4, 2022 in NotaLotofPeopleKnowThat

…

…

Because the data is compiled from the same EM-DAT da­tabase, the annual number of deaths shows an uptick from the 1990s to the 2000s. It is clear though that disaster-related deaths from extreme weather have been falling since the 1920s and are now approaching zero. This is due as much to improved planning, more robust structures and early warning systems, as it is to diminishing numbers of natural disasters. And, as can be seen from the figure, it is earthquakes – entirely natural events – that have been the deadliest disasters over the last two decades.

Ignoring all the evidence, however, the press release accompanying the latest WMO report proclaims that “Climate science is clear: we are heading in the wrong direction,” the UN Secretary-General adding, with characteristic hype, that the report “shows climate impacts heading into uncharted territory of destruction.”

A more detailed discussion of the erroneous claims of both CRED and the WMO can be found in my two most recent reports on weather extremes (here and here).

48 Of 79 ‘Catastrophic Climate’ Predictions Have Failed; Other 31 Haven’t Expired Yetrd,

by K. Richard,  Apr 9, 2021 in ClimateChangeDispatch

A new peer-reviewed paper published in the International Journal of Global Warmingidentifies 79 “apocalyptic” predictions formulated since 1970 by “researchers and activists” who “predict cataclysmic events” resulting from “catastrophic climate change.”

Already 48 of these “truly apocalyptic forecasts” have failed. The other 31 are likely just as wrong, but the prediction end dates haven’t expired yet, as “the apocalypse is always about 20 years out.”

Rode and Fischbeck are “professors of Social & Decision Sciences and Engineering & Public Policy” at Carnegie Mellon University.

In a new paper and press release (surprisingly published in AAAS) they have effectively exposed a “string of repeated apocalyptic forecast failures” over the last 50 years made by such activists/scientists as Al Gore, Paul Ehrlich, and Tim Flannery.

Activists/scientists James Hansen and Michael Mann have catastrophic predictions set to expire in the 2030s, and the IPCC had a cataclysmic forecast already fail and 3 others that will expire in 2029 and 2050 (2).

The authors’ intention was to warn the climate science community about the cry-wolf dangers of repeatedly making “extreme climate forecasts” that, when they inevitably fail, “undermine the trust in the underlying science.”

It is highly likely that these warnings will be ignored, however, as “making sensational predictions of the doom of humanity, while scientifically dubious, has still proven tempting for those wishing to grab headlines.”

What Happened To The Ice-Free Arctic?

by P. Homewood, Sep 26, 202 in NotaLotofPeopleKnowThat

I wonder how these predictions worked out? (Answers tomorrow!!)

Scientists in the US have presented one of the most dramatic forecasts yet for the disappearance of Arctic sea ice.

Their latest modelling studies indicate northern polar waters could be ice-free in summers within just 5-6 years.

Professor Wieslaw Maslowski told an American Geophysical Union meeting that previous projections had underestimated the processes now driving ice loss.

Summer melting this year reduced the ice cover to 4.13 million sq km, the smallest ever extent in modern times.

Remarkably, this stunning low point was not even incorporated into the model runs of Professor Maslowski and his team, which used data sets from 1979 to 2004 to constrain their future projections. “Our projection of 2013 for the removal of ice in summer is not accounting for the last two minima, in 2005 and 2007,” the researcher from the Naval Postgraduate School, Monterey, California, explained to the BBC.

“So given that fact, you can argue that may be our projection of 2013 is already too conservative.”

The Climate Scaremongers: The Great Arctic Sea Ice Scam

by P. Homewood, Sep 23, 2022 in ClimateChangeDispatch

 

 

For years the ‘experts’ have been telling us that the Arctic would soon be ice-free in summer.

Al Gore notoriously warned us in 2009 that ‘there is a 75 percent chance that the entire north polar ice cap, during the summer months, could be completely ice-free within five to seven years.’

He was, of course, just a politician. But a whole host of supposed Arctic scientists were all busy issuing similar warnings at the time. [bold, links added]

In 2007, for instance, Professor Wieslaw Maslowski told us that northern polar waters could be ice-free in summers within just five to six years.

In December of that year, Jay Zwally of Nasa agreed, giving the ice till 2012. A year later, in 2008 Professor David Barber went one step further, saying the ice would all be gone that very summer.

For sheer persistence in getting it wrong, however, the prize must go to Peter Wadhams, professor and head of the Polar Ocean Physics Group in the Department of Applied Mathematics and Theoretical Physics at the University of Cambridge:

…

• In 2012, he predicted that the Arctic would be ice-free by 2015/16.

• In 2014, he thought it might last till 2020.

• In 2016, he confidently predicted the Arctic would be ice-free that summer (though curiously he now defined ‘ice-free’ as less than 1 million square kilometers).

All these pronouncements were designed for political propaganda purposes, not for scientific reasons, and were widely propagated by the gullible media.

Is Global Warming The Greatest Scientific Fraud In History?

by G.K. Mitchell, Aug 19, 202 in ClimateChangeDispatch

…

In its seminal report in 1990, the U.N. IPCC stated that “at the then current rate of world emissions of CO2, the global mean temperature would likely increase by 1°C by 2025.”

This statement formed the basis for the hypothesis that anthropogenic (man-made) global warmingresulted from the increased concentration of CO2 in the Earth’s lower atmosphere resulting from man-made activities.

Central to the hypothesis was that the temperature of the lower troposphere would increase as the concentration of CO2 in the troposphere increased.

Therefore, in its 1990 report, the U.N. IPCC established a direct linkage between the concentration of CO2 in the atmosphere and the temperature of the lower troposphere.

The scientific method of inquiry has guided scientific research and investigation for over 400 years. In summary, the scientific method requires that a researcher observe a phenomenon, postulate a hypothesis for the cause of the phenomenon, and then conduct experiments or scientific investigations to falsify the hypothesis.

In adherence to the scientific method, a climate scientist who thinks that man has caused global warming should develop a complex hypothesis as follows:

  1. Global warming has occurred; that is, the temperature of the world’s oceans, landmass, and relevant atmosphere has risen during the period under investigation by a statistically significant amount.

  2. Man’s activities are responsible for the global warming that has occurred.

  3. The extent to which global warming has occurred, or is reasonably projected to occur in the future, will adversely affect life on Earth.

If any of the conjectures in the complex hypothesis above are found to be invalid, the complex hypothesis is determined to be falsified and either discarded or modified.

Friday Funny – Clownfish Climate Science

by A. Watts, Aug 12, 2022 in WUWT

Star marine ecologist committed misconduct, university says

Finding against Danielle Dixson vindicates whistleblowers who questioned high-profile work on ocean acidification [due to rising atmospheric CO₂ levels]

A major controversy in marine biology took a new twist last week when the University of Delaware (UD) found one of its star scientists guilty of research misconduct. The university has confirmed to Science that it has accepted an investigative panel’s conclusion that marine ecologist Danielle Dixson committed fabrication and falsification in work on fish behavior and coral reefs. The university is seeking the retraction of three of Dixson’s papers and “has notified the appropriate federal agencies,” a spokesperson says.

Among the papers is a study about coral reef recovery that Dixson published in Science in 2014, and for which the journal issued an Editorial Expression of Concern in February. Science—whose News and Editorial teams operate independently of each other—retracted that paper today.

The investigative panel’s draft report, which Science’s News team has seen in heavily redacted form, paints a damning picture of Dixson’s scientific work, which included many studies that appeared to show Earth’s rising carbon dioxide (CO₂) levels can have dramatic effects on fish behavior and ecology. “The Committee was repeatedly struck by a serial pattern of sloppiness, poor recordkeeping, copying and pasting within spreadsheets, errors within many papers under investigation, and deviation from established animal ethics protocols,” wrote the panel, made up of three UD researchers.

Dixson did not respond to requests for comment. She “adamantly denies any and all allegations of wrongdoing, and will vigorously appeal any finding of research misconduct,” Dixson’s lawyer, Kristina Larsen, wrote in an email to Science. Larsen describes Dixson as a “brilliant, hardworking female scientist” who was “targeted” by a group of scientists who “chose to ‘convict’ Dr. Dixson in the court of public opinion” by sharing their accusations with a Science reporter last year.

STUDY: 96% OF U.S. CLIMATE DATA IS CORRUPTED

by Heartland Institute, July 27, 2022

Official NOAA temperature stations produce corrupted data due to purposeful placement in man-made hot spots

Nationwide study follows up widespread corruption and heat biases found at NOAA stations in 2009, and the heat-bias distortion problem is even worse now

ARLINGTON HEIGHTS, IL (July 27, 2022) – A new study, Corrupted Climate Stations: The Official U.S. Surface Temperature Record Remains Fatally Flawed, finds approximately 96 percent of U.S. temperature stations used to measure climate change fail to meet what the National Oceanic and Atmospheric Administration (NOAA) considers to be “acceptable” and  uncorrupted placement by its own published standards.

The report, published by The Heartland Institute, was compiled via satellite and in-person survey visits to NOAA weather stations that contribute to the “official” land temperature data in the United States. The research shows that 96% of these stations are corrupted by localized effects of urbanization – producing heat-bias because of their close proximity to asphalt, machinery, and other heat-producing, heat-trapping, or heat-accentuating objects. Placing temperature stations in such locations violates NOAA’s own published standards (see section 3.1 at this link), and strongly undermines the legitimacy and the magnitude of the official consensus on long-term climate warming trends in the United States.

“With a 96 percent warm-bias in U.S. temperature measurements, it is impossible to use any statistical methods to derive an accurate climate trend for the U.S.” said Heartland Institute Senior Fellow Anthony Watts, the director of the study. “Data from the stations that have not been corrupted by faulty placement show a rate of warming in the United States reduced by almost half compared to all stations.”

NOAA’s “Requirements and Standards for [National Weather Service] Climate Observations” instructs that temperature data instruments must be “over level terrain (earth or sod) typical of the area around the station and at least 100 feet from any extensive concrete or paved surface.” And that “all attempts will be made to avoid areas where rough terrain or air drainage are proven to result in non-representative temperature data.” This new report shows that instruction is regularly violated.

Inconvenient truth for globalists: Arctic ice at 30-year high

by A. Moore, May 25, 2022 in Wind

The World Economic Forum and the globalist movement it helps lead have used the “climate crisis” and the COVID-19 pandemic as pretexts for measures to redistribute the wealth of nations.

But this week, as WEF convenes is annual conference in Davos, Switzerland, the Arctic sea ice expanse so far this month is at a 30-year high, according to data from intergovernmental European Organization for the Exploitation of Meteorological Satellites, points out climate-change skeptic Tony Heller.

EUMETSAT, as the organization is known,  was created through an international convention signed by 30 European nations.

The extent of Arctic ice during the warmer months long has been a metric for climate-change alarmists. In 2007, Al Gore began warning the world that scientists were predicting that by 2013, the Arctic would be ice-free during the summer.

The Global Warming Scare Is Most Certainly Overheated

by Edidorial Board, May 10, 2022 in Issue&Insight

Does anyone wonder where all the global warming destruction is? After all, the media are unrelenting in telling us how much climate change caused by man is affecting us. Yet no existential threat has emerged. There’s something off with the story.

The climate alarmists have based their predictions of doom on computer models that have been projecting global temperature increases, the likes of which, they tell us, are unsustainable. We must cut our carbon dioxide emissions, even if (actually, especially if) it hurts developed world economies.

This is the narrative we’re bombarded with on a daily basis. And it’s wrong.

Those models that have been used to fuel the fright are, without a doubt, unreliable. According to a recent story published in Nature magazine written by a group of climate modelers, “a subset of the newest generation of models are ‘too hot’ and project climate warming in response to carbon dioxide emissions that might be larger than that supported by other evidence.”

The authors, though, are careful to preserve the narrative, warning that “​​whereas unduly hot outcomes might be unlikely, this does not mean that global warming is not a serious threat.” They can’t help themselves.

While the modelers in the Nature article point specifically to problems with “a subset of the newest generation of models,” it’s obvious that the older models are no better. Last fall we covered a ScienceDaily report which noted that some researchers had concluded “a possible flaw in climate models” had been exposed, as the models failed to reproduce an observed event.

“When the history of climate modeling comes to be written in some distant future,” economist Robert L. Bradley Jr. wrote some months ago for the American Institute for Economic Research, “the major story may well be how the easy, computable answer turned out to be the wrong one, resulting in overestimated warming and false scares from the enhanced (man-made) greenhouse effect.”
