News Outlet Relies On Flawed ‘Attribution Studies’ To Blame Climate Change For Extreme Weather

by A. Watts, Nov 19,2024 in ClimateChaneDispatch

On Monday, November 18, The Guardian published an “explainer” piece titled “How do we know that the climate crisis is to blame for extreme weather?” This is false. [emphasis, links added]

Actual data on extreme weather does not support their claim, and the claim is mostly based on flawed “attribution studies.”

The narrative that severe weather events are worsening due to climate change has become a mainstay in today’s media. However, a closer look at the data and the science behind these claims often reveals inconsistencies that should give us pause.

Attribution studies, which are widely used to link specific extreme weather events to climate change, frequently lack rigorous peer review and are published hastily to garner headlines, raising significant concerns about their reliability.

Attribution studies work by using climate models to simulate two different worlds: one influenced by human-caused climate change and another without it. These models then assess the likelihood of extreme weather events in each world.

Yet the validity of such studies is only as good as the models and assumptions underpinning them.

This methodology is prone to overestimating risks because climate models often reflect overheated worst-case scenarios rather than actual observations.

Moreover, these studies are often published without proper peer review. Climate Realism has documented how media outlets run stories based on these model-driven studies, ignoring real-world data that often contradicts the alarming conclusions.

For example, articles frequently cite reports that heatwaves, floods, or hurricanes are “worsening” without disclosing that these claims rely on theoretical simulations rather than measured evidence.

Empirical data does not support claims of worsening severe weather. In fact, long-term trends for many extreme weather events have remained stable or even declined.

According to Climate at a Glance, heatwaves in the United States were most severe in the 1930s, with temperatures and frequency outstripping recent records.

The number of strong hurricanes making landfall in the United States has not increased either. The country even experienced a record 12-year lull in major hurricanes between 2005 and 2017.

Additionally, droughts have not intensified in the U.S. The nation saw historically low levels of drought in recent years, with 2017 and 2019 setting records for the smallest percentage of the country affected by drought. These data points highlight a crucial disconnect between what is reported and what is actually happening.

German Researcher: Doubling Of Atmospheric CO2 Causes Only 0.24°C Of Warming …Practically Insignificant

by P. Gosselin, Nov 19, 2024 in NoTricksZone

The CO2 scam and “climate denial”

German researcher concludes CO2 warming immensely exaggerated…. IR radiation of clouds considerably reduces the greenhouse effect of CO2.”

The prosperity and political stability of our countries are in grave danger. The reason for this is an ideology that claims catastrophic climate change caused by the alleged “greenhouse gas” CO2 and is intent to destroy our civilization and prosperity. Its supporters are spreading a witch-hunt atmosphere against anyone who questions their ideology. So-called “climate deniers” are also denied any scientific expertise.

Every Swiss person can already see the first financial consequences on their electricity bill: In this country, the price of a kilowatt hour has shot up by up to 300% for some households in just four years. And this is just the beginning, as the Swiss government is pursuing the goal of switching to solar and wind power and thus to sources that cost 20 instead of 6 rp/kWh.

…

…

Conclusions

In his summary, Prof. Reinhart comes to the following conclusions:

“- The heat retention (“forcing”) by atmospheric carbon dioxide (CO2 ) causes a maximum temperature increase of 0.24 K (0.24°C) when the concentration doubles from 400 ppm to 800 ppm, based on a simplified absorption model that is independent of climate.

– This value depends only on the accepted mean earth temperature, T = 288 K, and is relatively insensitive to its uncertainty of 2 K.

– The temperature increase since the industrial revolution amounts to a maximum of 0.12 K, which is within the range of measurement accuracy. The anthropogenic contribution is therefore practically insignificant.

– The behavior of glacial and current temperature trends is not causally linked to carbon dioxide concentrations.

– The causes of global warming have not been clarified. However, they are most likely linked to the solar system and the water cycle.

– Measures to control CO2 emissions and the earth’s temperature are unsuitable, even dangerous means”.

Climate scientists officially declare ‘climate emergency’ at an end

by ClintelGroup, Nov 20, 2024 in WUWT

The Chamber of Deputies in session

Climate scientists have issued a shock declaration that the “climate emergency” is over.

A two-day climate conference in Prague, organised by the Czech division of the international Climate Intelligence Group (Clintel), which took place on November 12-13 in the Chamber of Deputies of the Czech Republic in Prague, “declares and affirms that the imagined and imaginary ‘climate emergency’ is at an end”.

The communiqué, drafted by the eminent scientists and researchers who spoke at the conference, makes clear that for several decades climate scientists have  systematically exaggerated the influence of CO2 on global temperature.

The high-level scientific conference also declared:

“The Intergovernmental Panel on Climate Change, which excludes participants and published papers disagreeing with its narrative, fails to comply with its own error-reporting protocol and draws conclusions some of which are dishonest, should be forthwith dismantled.”

The declaration supports the conclusions of the major Clintel report The Frozen Climate Views of the IPCC [presented to the Conference by Marcel Crok, Clintel’s co-founder].

Moreover, the scientists at the conference declared that even if all nations moved straight to net zero emissions, by the 2050 target date the world would be only about 0.1 C cooler than with no emissions reduction.

So far, the attempts to mitigate climate change by international agreements such as the Paris Agreement have made no difference to our influence on climate, since nations such as Russia and China, India and Pakistan continue greatly to expand their combustion of coal, oil and gas.

The cost of achieving that 0.1 C reduction in global warming would be $2 quadrillion, equivalent to 20 years’ worldwide gross domestic product.

Finally, the conference “calls upon the entire scientific community to cease and desist from its persecution of scientists and researchers who disagree with the current official narrative on climate change and instead to encourage once again the long and noble tradition of free, open and uncensored scientific research, investigation, publication and discussion”.

The full text of the communiqué follows:

The International Scientific Conference of the Climate Intelligence Group (Clintel), in the Chamber of Deputies of the Czech Republic in Prague assembled on the Twelfth and Thirteenth Days of November 2024, has resolved and now declares as follows, that is to say –

  1. The modest increase in the atmospheric concentration of carbon dioxide that has taken place since the end of the Little Ice Age has been net-beneficial to humanity.
  2. Foreseeable future increases in greenhouse gases in the air will probably also prove net-beneficial.
  3. The rate and amplitude of global warming have been and will continue to be appreciably less than climate scientists

The Climate Case of the Century

by L. Bergkamp, Nov 14, 2024 in WUWT

On the 12th of November, the Hague Court of Appeal ruled in the “climate case of the century” that Milieudefensie (“FoE”) filed against Shell in 2019. FoE demands that Shell reduce emissions throughout the entire chain by at least 45% by 2030. The foundation “Man & Environment” (M&E) joined the case to represent the interests of Dutch citizens.

The Court of Appeal was not impressed by FoE’s “go green or go extinct” rhetoric and rejected its claims.  Nevertheless, the Court of Appeal’s ruling leaves much to be desired and did not eliminate the threat of activist NGOs launching climate cases to effect “system change,” i.e., set aside democracy, subordinate citizens and destroy the economy.

Climate science

Although M&M had offered strong rebuttals with expert reports, the Court of Appeal uncritically adopted many of FoE’s factual statements about the urgency and seriousness of the climate problem.  In doing so, the Court relied on the authority of the IPCC and the alleged “consensus” that would emerge from their reports, in particular the SPMs.

The Court not only took the IPCC reports as irrebuttable proof, but also attributed normative force to them. For example, the Court ruled that climate scientists have determined that the average temperature on earth may not rise by more than 1.5 degrees. In doing so, the Court, like the Dutch Supreme Court, ignored that science cannot set norms and that scientists are not authorized to set social standards. The Dutch judiciary’s scientistic tendency is extremely worrisome and does not bode well for future climate-related judgments.

Climatologists Shocked By Nature Op-Ed Arguing Objectivity In Climate Science Is Problematic

by K. Killough, Nov 13, 2024 in ClimateChangeDispatch

protest 15 degrees

Three climate researchers took to the pages of Nature to argue that objectivity in climate science is problematic because it hinders their political advocacy, which they argue is too important to deny. [emphasis, links added]

Therefore, the authors argue, the values of objectivity in scientific research should be reconsidered.

“The public has watched as national and sub-national governments have declared climate emergencies, all the while continuing to grant new permits for the extraction of fossil fuels, seemingly ignoring increasingly urgent scientific messages that this locks the world into passing 1.5 °C of warming above preindustrial levels by 2030, if not sooner,” the researchers explain.

While the researchers equate a refusal to stop the production of fossil fuels with ignoring science, energy experts argue these policies will result in enormous economic problemsand widespread poverty.

The authors of the Nature op-ed, seemingly unaware or unconcerned with the impacts of such policies, argue that it’s unfair to expect climate researchers not to get emotional when governments don’t adopt these policies. 

“Scientists who express their feelings and worries about climate change are often not encouraged by their colleagues and are instead expected to carry on without acknowledging or communicating the continued inadequacy of action required to secure a liveable and sustainable future,” the authors state.

By just about every measure — including life expectancy, wealth, and deaths from natural disasters— the human race is doing better than ever. Despite this, the authors believe their fears are based on indisputable facts.

Azerbaijan’s COP29 Speech: A Masterclass in Irony So Thick, It’s Flammable

by C. Rotter, Nov 13, 2024 in WUWT

Picture this: COP29, the annual climate circus where the world’s leaders gather to wag fingers and wring hands over carbon emissions, is hosted in none other than Azerbaijan—a country whose economy runs on fossil fuels like a muscle car guzzling premium gas. Then comes the pièce de résistance: Azerbaijan’s President Ilham Aliyev steps up to the mic and declares oil and gas to be “God’s gift” to his nation.

…

You can’t make this up. It’s like hosting a vegan potluck and having the guest of honor arrive with a tray of prime rib.

The “Climate” Conference in an Oil Nation

Let’s start with the hilarious choice of venue. Azerbaijan is one of those countries where crude oil isn’t just a commodity—it’s practically a national sport. Hosting COP29 in Baku is akin to holding a Weight Watchers meeting in a donut shop. And yet, the global climate elites packed their bags and flew to the Land of Hydrocarbons to sit through speeches about how we’re all doomed unless we ban the very thing that keeps Azerbaijan afloat.

The irony was lost on precisely no one except, apparently, the COP29 organizers.

Green Grifters: Another elite-laden conference demonstrates the staggering hypocrisy of climate-change activism

by H. Mac Donald, Nov 12, 2024 in /CityJournal

The latest global climate conference opened Monday in Azerbaijan. The timing is excellent. Any doubt regarding the wisdom of the next Trump administration’s likely pullout from such meetings should be dispelled by the conference photos alone. Here are tens of thousands of well fed, well-dressed members of the global elite—activists, employees of lavishly funded NGOs, armies of government bureaucrats, hundreds of heads of state—who have all travelled via jet and private plane to this remote corner of the Earth and who expect that every minute of their day will be supported by abundant, magically available energy. None has sacrificed a single personal comfort to save the planet. They assume that their smartphones will draw on an invisible web of transmitters and that they will be able to search the Internet and run AI queries at will, notwithstanding that doing so requires voracious energy use from a growing archipelago of server farms. They expect their PowerPoints to be well lit and their conference and hotel rooms to be heated or air conditioned as needed. They’re never without their bottled water, which is carried thousands of miles by carbon-emitting trucks and planes and kept sterile by plastic containers whose manufacture requires petrochemicals and plenty of energy. They do not wait on the sun to shine or the wind to blow to light their rooms, run their elevators, or power up their devices; they want energy now and without interruption.

You don’t have to be a “climate denier” to see that climate-change politics have become the largest global grift in history, one that grows in proportion with each new conference. It was just a matter of time before Third World basket-case countries exploited the First World’s virtue signaling. This year’s UNFCC COP 29 conference in Azerbaijan (COP stands for Conference of the Parties) features the demand that developed countries fork over billions, if not trillions, more dollars to the Global South, ostensibly to help it adjust to climate change. Those billions will follow all previous foreign aid into the same sinkhole of corruption and incompetence.

Hague court denies claim for reduction in Shell’s CO2 emissions

by The Hague, 12 November 2024, in deRechtspraak

The Hague Court of Appeal today handed down its judgment in the appeal proceedings between Milieudefensie and Shell. At issue in the appeal was whether Shell must have reduced its CO2 emissions by 45% in 2030 compared to 2019. The court of appeal ruled that Shell is obliged to reduce its CO₂ emissions, but that it was unable to determine which percentage should apply. The court of appeal therefore rejected the claims of Milieudefensie.

According to Milieudefensie, Shell is acting unlawfully. Milieudefensie is of the opinion that under the social standard of care, Shell is obliged to reduce its CO2 emissions. Milieudefensie and several other environmental organisations submitted a claim for Shell to reduce its CO2 emissions by 45% in 2030 compared to 2019. This includes Shell’s own CO2 emissions as well as those of its suppliers and customers, known as scope 1, 2 and 3 emissions.

The Hague District Court upheld the claim of Milieudefensie, after which Shell lodged an appeal. The Stichting Milieu en Mens joined as a party in the proceedings before the court of appeal on the side of Shell.

In today’s judgment, the court of appeal held that Shell has an obligation towards citizens to limit its CO2 emissions. This obligation is based on the human right to protection against dangerous climate change. It is first and foremost up to governments to ensure the protection of human rights, but indirectly those rights also have a bearing on the social standard of care which companies like Shell must observe. In its assessment of whether Shell is acting unlawfully, the court of appeal therefore took as a starting point that citizens also have a right vis-à-vis Shell to protection from dangerous climate change.

Nevertheless, the court of appeal denied the claims of Milieudefensie because the court was unable to establish that the social standard of care entails an obligation for Shell to reduce its CO2 emissions by 45%, or some other percentage. There is currently insufficient consensus in climate science on a specific reduction percentage to which an individual company like Shell should adhere. Moreover, Shell is already working to reduce its own scope 1 and 2 emissions. Lastly, the court of appeal is of the opinion that an obligation for Shell to reduce CO2 emissions caused by buyers of Shell products, scope 3 emissions, by a particular percentage would be ineffective in this case. Shell could meet that obligation by ceasing to trade in the fuels it purchases from third parties. Other companies would then take over that trade. This would consequently not result in a reduction in CO2 emissions.

In conclusion, The Hague Court of Appeal overturned the district court’s judgment and denied the claims of Milieudefensie. An appeal in cassation against this ruling may be brought before the Dutch Supreme Court.

Media Hypes Report That 2024 Will Break 1.5°C Limit, But Data Doesn’t Back It Up

by L. Lueken, Nov 11, 2024 in ClimateChangeDispatch

valencia flood aftermath

Multiple outlets have posted articles covering a report from the European Copernicus Climate Change Service (“Copernicus”) which says that 2024 will be the first to surpass 1.5°C warming since preindustrial times, which the media claims will cause untold weather disasters. [emphasis, links added]

This is mostly false.

Although 2024 will likely have higher average temperatures than in recent decades, it is not the end of the year yet, and there is limited evidence to support the claim that it will represent the highest temperatures humans have ever experienced and no evidence whatsoever that weather disasters have gotten or will get worse.

The BBC and CNN are among the numerous mainstream media outlets reporting on Copernicus’ report.

CNN describes the report as “devastating news for the planet that comes as America chooses a president that has promised to undo its climate progress both at home and abroad.”

The Copernicus group estimates that 2024 will end up 1.55°C hotter than the 1850-1900 average, which is 0.05°C above the warming limit set by the Paris Agreement. This may be true, but there is no evidence that the 1.5℃ threshold is some kind of deadly tipping point for weather disasters.

The same organization sounded the alarm last year that the “limit” was breached for several months in a row while ignoring natural factors like an underwater volcano eruption.

As for the 1.5-degree limit itself, it was not established by professional climate scientists. Only one of the people who were on the panel who came up with the value was even a meteorologist.

Two other points worth noting. The claim is a bit of sleight of hand, cherry-picking the data for comparison. Earth was only just coming out of the Little Ice Age at the onset of the 1850 period, one of the coldest periods during the past millennia.

When you pick an unusually cold period for comparison, modest warming seems more dramatic than it is.

Second, the 1.5℃ is an arbitrary temperature choice. As Climate Realism has discussed repeatedly here, here, and here, it was chosen by politicians for political reasons.

There is no scientific evidence it represents some tipping point for catastrophic climate change. The world has likely warmed more than 2°C since the 1700s, with no apocalypse.

One would think that if warming causes more extreme weather there would be solid data and identifiable consistent trends showing an increase in extreme weather, but there is none.

Three of the weather events CNN cites at the end of their article as proof of a supposed climate emergency, Hurricane Milton, the flooding in Spain, and low snow amounts at Mt. Fuji are not proof of a climate emergency.

New Study: Human Contribution To Enhancement Of Earth’s Greenhouse Effect A Negligible 0.2 Percent

by K. Richard, Nov 12, 2024 in NoTricksZone

“[T]he contribution of CO2 to the greenhouse effect is 4% – 5%. Human CO2 emissions represent 4% of the total, which means that the total human contribution to the enhancement of the greenhouse effect is 0.16% to 0.20% – a negligible effect.” – Dr. Demetris Koutsoyiannis (2024)

New research exposes the vacuousness of the “imaginary world” models proclaiming CO2 the dominant regulator of the Earth’s climate.

A CO2-less or CO2-only atmosphere…an imaginary-world thought experiment

An oft-heard claim is that, due to the prominence of CO2 as the Earth’s climate “control knob” (see Lacis et al., 2010), the greenhouse effect could not exist – indeed, it would collapse – if there was no CO2 in the atmosphere.

However, it should go without saying that this CO2-less atmospheric condition itself is an imaginary-world conceptualization. Thus, fantasizing about what would happen if the atmosphere was comprised 0 ppm CO2, 1,000,000 ppm CO2, 0 ppm water vapor…are all just untestable, never-observable thought experiments. They cannot be subjected to the scientific method. Thus, they are unfalsifiable.

CO2’s climate effects are undetectable

Of course, this very unfalsifiable thought experiment is what believers in the CO2-is-the-climate-control-knob narrative rest their case on. But even if we do use this imaginary-world premise, the existing models (MODTRAN, HITRAN) that allegedly support the CO2-controls-climate orthodoxy actually undermine it.

For example, as Dr. Koutsoyiannis points out in his extensively-referenced paper, the MODTRAN data show that the Earth’s temperature remains at the default greenhouse-effect value if the water vapor scale is adjusted upwards slightly, by just 30%. The greenhouse effect does not “collapse” as claimed by Lacis et al. disciples – the control-knob believers.

The HITRAN database also indicates the imaginary-world condition of doubling CO2 from 400 to 800 ppm would only alter the radiation flux at the top of the atmosphere by -1.1%, a hypothetical realization that could not even be detected in future macroscopic measurements (if the atmosphere ever were to reach a CO2 concentration of 800 ppm).

MODTRAN models further affirm that (1) there is only a 1% temperature difference between either doubling (800 ppm) or halving (200 ppm) the atmospheric CO2 concentration, and (2) the change in the downwelling radiation resulting from an increase from 300 ppm (1900) to 420 ppm (2023) is only 0.5%. These tiny changes “could not be discerned by observations.”

Despite Media Panic, There Is No Reason to Think 2024’s Warming Is Disastrous

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

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

Abstract

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

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

by K. Richard, Oct 14, 2024 in NoTricksZone

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

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

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

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

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

El Niño fingered as likely culprit in record 2023 temperatures

by P. Voosen, Oct 10, 2024 in Science

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

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

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

First published 9 October 2024

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

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

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

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

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

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

by L. Hamlin, Oct 7, 2024 in ClimateChangeDispatch

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

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

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

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

by C. Morrison, Oct 10, 2024 in WUWT

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

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

Of The Top 10 Deadliest Hurricanes in U.S. History, Most Occurred Over A Century Ago

by G. Martinez, Oct 7, 2024 in ClimateChangeDispatch

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

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

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

10. Last Island hurricane (1856)

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

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

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

9. Labor Day hurricane (1935)

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

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

From Dr. Roy Spencer’s Global Warming Blog.

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

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

Global land: +1.35 deg. C

Southern Hemisphere land: +1.87 deg. C

Southern Hemisphere extratropical land: +2.23 deg. C

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

Australia: +1.80 deg. C.

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

The following table lists various regional LT departures from the 30-year (1991-2020) average for the last 20 months (record highs are in red):

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

by K. Richard, Sept 2, 2027 in NoTricksZone

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

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

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

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

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

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

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

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

by K. Richard, Aug 30, 2024 in WUWT

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

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

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

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

Per the IPCC:

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

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

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

…

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

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

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

The Solar Control of Climate: A Review

by D. Archibald,  Aug 28, 2024 in TheWentworthReport

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

…

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

 

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

Global Temperature updated for August 2024

by C. Best, Aug 27, 2024 in SciTravelOpinion

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

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

Temperature trends

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

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

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

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

by C. Rotter, Aug 24, 2024 in WUWT

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

Fossil Fuels: The Workhorse of Florida’s Energy Grid

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

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

The Reality of Renewable Energy

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

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