Advance Briefing for COP29 Baku 2024

Posted on by Ron Clutz

Overview from CFR. COP29 Summit in Baku: What to Expect  Excerpts in italics with my bolds and added images.

Negotiators from across the globe will gather in Baku, Azerbaijan, for the twenty-ninth annual UN climate change conference on November 11. COP29 marks the midpoint of the “COP Presidencies Troika,” a collaborative effort between the United Arab Emirates (UAE, host to COP28) and Brazil (host to COP30 in 2025) aimed at accelerating progress toward the 1.5°C goal. Unlike COP28 in Dubai last year, which hosted a record hundred thousand attendees, COP29 will be smaller, with Baku expected to host around fifty thousand participants. 

The selection of Azerbaijan as the host country has raised concerns about the credibility and integrity of the COP process. COP29 marks the third time a significant fossil fuel-producing country has hosted the conference, and the second time in two years. Azerbaijani President Ilham Aliyev has announced plans to increase gas production in part to satisfy European Union (EU) demands and referred to the country’s oil and gas reserves as “a gift from God.” 

What’s on the Agenda–Three Pledges Are Proposed

Reducing emissions and increasing green energy. The presidency has put forward a series of commitments for investing in renewable energy, such as a Global Energy Storage and Grids Pledge, which aims to enhance energy infrastructure and storage capabilities worldwide, an ambitious Hydrogen Declaration, and a Declaration on Reducing Methane from Organic Waste. With the Green Digital Action Declaration, COP29 leadership seeks to reduce emissions in the information and communication sectors. The agenda, however, makes no direct mention of a transition from fossil fuels.

Building climate resilience. The COP presidency has put forth a climate initiative for farmers and a declaration calling for integrated approaches to combating climate threats to water basins and ecosystems. Additionally, Baku aims to present the Initiative on Human Development for Climate Resilience, which focuses on education, skills, health, and well-being, and the COP29 Multisectoral Actions Pathways (MAP) Declaration that aims to enhance urban climate resilience.  

New climate finance targets. Nations are expected to replace the previous $100 billion annual commitment to developing countries from the 2009 Copenhagen Accord. The new target, known as the New Collective Quantified Goal (NCQG), will be under discussion at November’s COP and is intended to take effect from 2025 onwards. A 2022 report [PDF] by the Independent High-level Expert Group on Climate Finance found that developing countries need around $1 trillion per year by 2025, and $2.4 trillion by 2030 to meet their climate finance needs.  Among the most contentious issues that remain are how much money developed nations will provide, and who should provide climate finance. 

Yes, those are Trillions of US$ they are projecting to spend.

My Comments

Since there is a big push on climate funding, maybe they could get to the bottom of this:

Maybe donors are put off by no one knowing who gets the money and for what it is spent.  And while they are investigating, how about understanding Energy Return on Investment (EROI): you know, the notion that an energy project is worth doing if the energy produced is greater than energy spent. The windmills in the logo at the top reminded me of this:

Why a COP Briefing?

Actually, climate hysteria is like a seasonal sickness.  Each year a contagion of anxiety and fear is created by disinformation going viral in both legacy and social media in the run up to the annual autumnal COP.  Since the climatists have put themselves at the controls of the formidable US federal government, we can expect the public will be hugely hosed with alarms over the next few weeks.  Before the distress signals go full tilt, individuals need to inoculate themselves against the false claims, in order to build some herd immunity against the nonsense the media will promulgate. This post is offered as a means to that end.

Media Climate Hype is a Cover Up

Back in 2015 in the run up to Paris COP, French mathematicians published a thorough critique of the raison d’etre of the whole crusade. They said:

Fighting Global Warming is Absurd, Costly and Pointless.

  • Absurd because of no reliable evidence that anything unusual is happening in our climate.
  • Costly because trillions of dollars are wasted on immature, inefficient technologies that serve only to make cheap, reliable energy expensive and intermittent.
  • Pointless because we do not control the weather anyway.

The prestigious Société de Calcul Mathématique (Society for Mathematical Calculation) issued a detailed 195-page White Paper presenting a blistering point-by-point critique of the key dogmas of global warming. The synopsis with links to the entire document is at COP Briefing for Realists

Even without attending to their documentation, you can tell they are right because all the media climate hype is concentrated against those three points.

Finding: Nothing unusual is happening with our weather and climate.
Hype: Every metric or weather event is “unprecedented,” or “worse than we thought.”

Finding: Proposed solutions will cost many trillions of dollars for little effect or benefit.
Hype: Zero carbon will lead the world to do the right thing.  Anyway, the planet must be saved at any cost.

Finding: Nature operates without caring what humans do or think.
Hype: Any destructive natural event is blamed on humans burning fossil fuels.

How the Media Throws Up Flak to Defend False Suppositions

The Absurd Media:  Climate is Dangerous Today, Yesterday It was Ideal.

Billions of dollars have been spent researching any and all negative effects from a warming world: Everything from Acne to Zika virus.  A recent Climate Report repeats the usual litany of calamities to be feared and avoided by submitting to IPCC demands. The evidence does not support these claims. An example:

 It is scientifically established that human activities produce GHG emissions, which accumulate in the atmosphere and the oceans, resulting in warming of Earth’s surface and the oceans, acidification of the oceans, increased variability of climate, with a higher incidence of extreme weather events, and other changes in the climate.

Moreover, leading experts believe that there is already more than enough excess heat in the climate system to do severe damage and that 2C of warming would have very significant adverse effects, including resulting in multi-meter sea level rise.

Experts have observed an increased incidence of climate-related extreme weather events, including increased frequency and intensity of extreme heat and heavy precipitation events and more severe droughts and associated heatwaves. Experts have also observed an increased incidence of large forest fires; and reduced snowpack affecting water resources in the western U.S. The most recent National Climate Assessment projects these climate impacts will continue to worsen in the future as global temperatures increase.

Alarming Weather and Wildfires

But: Weather is not more extreme.


And Wildfires were worse in the past.
But: Sea Level Rise is not accelerating.

post-glacial_sea_level

Litany of Changes

Seven of the ten hottest years on record have occurred within the last decade; wildfires are at an all-time high, while Arctic Sea ice is rapidly diminishing.

We are seeing one-in-a-thousand-year floods with astonishing frequency.

When it rains really hard, it’s harder than ever.

We’re seeing glaciers melting, sea level rising.

The length and the intensity of heatwaves has gone up dramatically.

Plants and trees are flowering earlier in the year. Birds are moving polewards.

We’re seeing more intense storms.

But: Arctic Ice has not declined since 2007.

But: All of these are within the range of past variability.In fact our climate is remarkably stable, compared to the range of daily temperatures during a year where I live.

And many aspects follow quasi-60 year cycles.

The Impractical Media:  Money is No Object in Saving the Planet.

Here it is blithely assumed that the UN can rule the seas to stop rising, heat waves to cease, and Arctic ice to grow (though why we would want that is debatable).  All this will be achieved by leaving fossil fuels in the ground and powering civilization with windmills and solar panels.  While admitting that our way of life depends on fossil fuels, they ignore the inadequacy of renewable energy sources at their present immaturity.

An Example:
The choice between incurring manageable costs now and the incalculable, perhaps even irreparable, burden Youth Plaintiffs and Affected Children will face if Defendants fail to rapidly transition to a non-fossil fuel economy is clear. While the full costs of the climate damages that would result from maintaining a fossil fuel-based economy may be incalculable, there is already ample evidence concerning the lower bound of such costs, and with these minimum estimates, it is already clear that the cost of transitioning to a low/no carbon economy are far less than the benefits of such a transition. No rational calculus could come to an alternative conclusion. Defendants must act with all deliberate speed and immediately cease the subsidization of fossil fuels and any new fossil fuel projects, and implement policies to rapidly transition the U.S. economy away from fossil fuels.

But CO2 relation to Temperature is Inconsistent.

But: The planet is greener because of rising CO2.

But: Modern nations (G20) depend on fossil fuels for nearly 90% of their energy.

But: Renewables are not ready for prime time.

People need to know that adding renewables to an electrical grid presents both technical and economic challenges.  Experience shows that adding intermittent power more than 10% of the baseload makes precarious the reliability of the supply.  South Australia is demonstrating this with a series of blackouts when the grid cannot be balanced.  Germany got to a higher % by dumping its excess renewable generation onto neighboring countries until the EU finally woke up and stopped them. Texas got up to 29% by dumping onto neighboring states, and some like Georgia are having problems.

But more dangerous is the way renewables destroy the economics of electrical power.  Seasoned energy analyst Gail Tverberg writes:

In fact, I have come to the rather astounding conclusion that even if wind turbines and solar PV could be built at zero cost, it would not make sense to continue to add them to the electric grid in the absence of very much better and cheaper electricity storage than we have today. There are too many costs outside building the devices themselves. It is these secondary costs that are problematic. Also, the presence of intermittent electricity disrupts competitive prices, leading to electricity prices that are far too low for other electricity providers, including those providing electricity using nuclear or natural gas. The tiny contribution of wind and solar to grid electricity cannot make up for the loss of more traditional electricity sources due to low prices.

These issues are discussed in more detail in the post Climateers Tilting at Windmills

The Irrational Media:  Whatever Happens in Nature is Our Fault.

An Example:

Other potential examples include agricultural losses. Whether or not insurance
reimburses farmers for their crops, there can be food shortages that lead to higher food
prices (that will be borne by consumers, that is, Youth Plaintiffs and Affected Children).
There is a further risk that as our climate and land use pattern changes, disease vectors
may also move (e.g., diseases formerly only in tropical climates move northward).36 This
could lead to material increases in public health costs

But: Actual climate zones are local and regional in scope, and they show little boundary change.

But: Ice cores show that it was warmer in the past, not due to humans.

The hype is produced by computer programs designed to frighten and distract children and the uninformed.  For example, there was mention above of “multi-meter” sea level rise.  It is all done with computer models.  For example, below is San Francisco.  More at USCS Warnings of Coastal Floodings

In addition, there is no mention that GCMs projections are running about twice as hot as observations.

Omitted is the fact GCMs correctly replicate tropospheric temperature observations only when CO2 warming is turned off.

Figure 5. Simplification of IPCC AR5 shown above in Fig. 4. The colored lines represent the range of results for the models and observations. The trends here represent trends at different levels of the tropical atmosphere from the surface up to 50,000 ft. The gray lines are the bounds for the range of observations, the blue for the range of IPCC model results without extra GHGs and the red for IPCC model results with extra GHGs.The key point displayed is the lack of overlap between the GHG model results (red) and the observations (gray). The nonGHG model runs (blue) overlap the observations almost completely.

In the effort to proclaim scientific certainty, neither the media nor IPCC discuss the lack of warming since the 1998 El Nino, despite two additional El Ninos in 2010 and 2016.

Further they exclude comparisons between fossil fuel consumption and temperature changes. The legal methodology for discerning causation regarding work environments or medicine side effects insists that the correlation be strong and consistent over time, and there be no confounding additional factors. As long as there is another equally or more likely explanation for a set of facts, the claimed causation is unproven. Such is the null hypothesis in legal terms: Things happen for many reasons unless you can prove one reason is dominant.

Finally, advocates and IPCC are picking on the wrong molecule. The climate is controlled not by CO2 but by H20. Oceans make climate through the massive movement of energy involved in water’s phase changes from solid to liquid to gas and back again. From those heat transfers come all that we call weather and climate: Clouds, Snow, Rain, Winds, and Storms.

Esteemed climate scientist Richard Lindzen ended a very fine recent presentation with this description of the climate system:

I haven’t spent much time on the details of the science, but there is one thing that should spark skepticism in any intelligent reader. The system we are looking at consists in two turbulent fluids interacting with each other. They are on a rotating planet that is differentially heated by the sun. A vital constituent of the atmospheric component is water in the liquid, solid and vapor phases, and the changes in phase have vast energetic ramifications. The energy budget of this system involves the absorption and reemission of about 200 watts per square meter. Doubling CO2 involves a 2% perturbation to this budget. So do minor changes in clouds and other features, and such changes are common. In this complex multifactor system, what is the likelihood of the climate (which, itself, consists in many variables and not just globally averaged temperature anomaly) is controlled by this 2% perturbation in a single variable? Believing this is pretty close to believing in magic. Instead, you are told that it is believing in ‘science.’ Such a claim should be a tip-off that something is amiss. After all, science is a mode of inquiry rather than a belief structure.

Summary:  From this we learn three things:

Climate warms and cools without any help from humans.

Warming is good and cooling is bad.

The hypothetical warming from CO2 would be a good thing.

 

 

Fear + Ignorance = Climate Alarm

Posted on by Ron Clutz

Mark C. Ross explains the syndrome in his American Thinker article Fear plus ignorance equals climate change.  Excerpts in italics with my bolds and added images.

Weather is inherently mysterious. Multiple forces, such as wind, clouds, seasonal and day-night cycles, and air pressure are constantly interacting and causing continuous chaos. In the aftermath of two particularly destructive hurricanes, the fear-mongers are bloviating to the max over the catastrophic effects on the climate caused by human existence.

And yet there is no discernible trend toward either more storms or more intense hurricanes compiled over more than beyond the last century. (This chart by NOAA was especially easy to find.) Thus far, the decade of the 1940s saw the most seriously intense storms. Being historical data, this brings to mind a modification of Santayana’s famous adage: when people are ignorant of their history, they make it really easy for demagogues to lie to them about it.

Rather than human consumption of fossil fuels, two other factors are mostly relevant when it comes to the damage wrought by hurricanes: the path they take and the development of infrastructure within that path. Out on the open sea, a hurricane may damage a few ships, but when one goes over a population center…well, you know, it just happened.

What determines the path is largely chaotic. Go figure. There’s this weird thing called the jet stream, which is sort of the result of the Earth’s continuous rotation within a tenuous atmospheric envelope. Becoming known to American aviators during World War 2, the particular details of the jet stream were kept as a military secret well into the mid-twentieth century. Ocean currents and surface temperatures are also involved. Early forecasts of hurricane paths are typically all over the map. As the time frame compresses, they tend to become more accurate, but not always.

Then there’s the “atypically” warm weather that sometimes happens in early autumn. We just had some of that, along with offshore winds and seriously elevated fire danger. In the olden days, this was called “Indian summer.” Back in 1919, Victor Herbert even wrote a song by that name. Maybe I’m just a cynic, but I’m expecting the fear-mongers to start pandering to the general public’s pervasive ignorance of earth science to cause panic over yet another routine weather event.

There are three scientific disciplines that are especially useful when looking at weather and climate of the distant past: geology; paleontology; and tree ring analysis, known as dendrochronology. Geology shows us the impact glaciers have had on the Earth’s surface. Paleontology shows us the now extinct life forms that thrived under previous environmental conditions. Dendrochronology shows us a preserved record of ancient weather conditions such as year-to-year rainfall and temperature.

How warm would the weather have to be for giant reptiles to flourish all over the Earth? Pretty warm, it seems. There is some work afoot to show that dinosaurs may have been warm-blooded. Good luck with that. Birds are the first known warm-blooded animals, and they evolved from reptiles and still tend to have scales on their legs. Mammals are also warm-blooded. Enormously large mammals such as wooly mammoths were common during the last ice age, the Pleistocene. Having a large size is especially beneficial for warm-blooded animals in cold climates, since surface area of the outer skin increases much more slowly than the actual body mass, making the large animal significantly more thermally efficient than a smaller one.

But why is the blatant climate change hoax still being promoted? There are two different reasons. The first is held among the true believers: humans are evil. They recklessly continue to damage the Earth’s biosphere, just for trivial benefits and without the slightest concern for the consequences of their actions. The other is political: fear can be a terrific motivator but is not all that conducive to good decision-making. That’s fine, too. The wannabe mega-state tyrants l-o-v-e to deal with fear and poor decision-making. How else can they effectively enslave the masses so as to fulfill their objectives?

And what are these objectives? Taking control of everything comes to mind. The evil players in politics are mostly after control. The rest of us just want to have the streets swept and the criminals pulled away from the rest of us. The term Statist should replace Marxist in this dialogue. Absolute government authority should overcome the self-direction of the individual — since so many among us are not really attuned to proper functionality in the modern world.

Socialism was already in the works when Karl Marx got involved. I like to say that a communist is an angry socialist. Marx injected class struggle into the quest for ownership of the means of production. Thus, the USA was a tough sell for Marxism since we are a particularly socially mobile society. The late, great Walter E. Williams would often say that the ranks of the one-percenters were constantly changing — since new ones would rise up, while others would blow it and fall away. The “Old World,” by contrast, is littered with caste systems and other forms of enforced social order.

Back to Caddell’s “elite gentry” — their desires are in mortal conflict with the aspirations of just plain folks. Or as Lincoln said, “God must love the common man, for he made so many of them.” To some, populism is a dirty word. To others, it is a path into the future. It can mean different things to different people. I like to use the term personal freedom. We can do what we want — as long as we don’t interfere with the freedom of others. But to others, “freedom” is a dirty word.

Methane False Alarm, Microbes Are to Blame

Posted on by Ron Clutz

Home fireplace burning Nat Gas, which is 75% methane (CH4).

Jo Nova explains at her blog Mysterious record methane surge since 2020 was not fossil fuels but “90% due to microbes”.  Excerpts in italics with my bolds and added images.

Nobody checked the carbon-13 ratios!

Wouldn’t you know it — 150 nations signed the Global Methane Pledge without even bothering to check if the methane was man-made.

Methane — the second most hated Greenhouse gas — spiked to record historic levels in the last few years, over 1,900 parts per billion.  In 2019, even the WEF scientists admitted they couldn’t explain the baffling rise, and then in 2020, the world of methane went into the twilight zone.  We shut down the modern world due to the pandemic, and methane levels rose even faster.

It seems many have been blaming fossil fuels for the global
surge in emissions, but forgot to check the C13 isotopes.

Somehow we spend millions on breathalysing cows, measuring their burps, and feeding them seaweed, but didn’t think to do the basic chemistry. How could that be, you might wonder… 158 nations agreed to cut methane emissions by 30% by 2030, but none of them audited the science even though very strange things were happening. (The point was obviously the “pledge”, the junkets, the captive industries and subsidies, anything but the science).

Methane from fossil fuels has a higher carbon-13 ratio, but even though fossil fuel use was rising, the carbon-13 levels of atmospheric methane was rolling down a hill. Indeed this new study shows it’s been falling for 17 years.

It’s not like this snuck up on us….  any inquiring mind should have seen this coming a decade ago. The lab has been recording C13 in methane since 1998 and gets air samples from 22 sites around the world every week or two.

From the press release:

Microbes in environment drove methane emissions more than fossil fuels between 2020 and 2022, analysis finds

They found that between 2020 and 2022, the drastic increase in atmospheric methane was driven almost entirely by microbial sources. Since 2007, scientists have observed microbes playing a significant role in methane emissions, but their contribution has surged to over 90% starting in 2020.

“Some prior studies have suggested that human activities, especially fossil fuels, were the primary source of methane growth in recent years,” said Xin (Lindsay) Lan…

“These studies failed to look at the isotope profile of methane…

They go on to mention that in a warmer world, bacteria have a higher metabolism, which means they are happier and work faster. Thus, like CO2, if the world warms for any reason at all, methane will rise — and there is nothing we can do about it.

The one last straw they could clutch is that maybe the microbes were “man-made” :  It remains unclear whether the increased microbial emissions came from natural sources like wetlands or human-driven sources, such as landfills and agriculture. The team plans to delve deeper to identify the exact source of methane.

As if somehow there was a surge in landfill, rice paddies
or cows in the last few years that no one had noticed.

This is a pretty big deal — methane has supposedly caused about 30% of our current temperature rise (says the broken climate models) yet 90% of that recent rise was microbes. It’s yet another slice of the climate we aren’t controlling, but we’re still designing burgers with mealworms and bacon from fungus, in the hope of reducing methane emissions and controlling the weather.  Then it turns out every swamp and square meter of soil is working against us.

Methane concentrations in the air have almost tripled since the 1700s, but that was the Little Ice Age.  It’s easy to believe that as the world warmed up, the planet’s wetlands and soil microbes have just been returning to normal business for the last 300 years.

We skeptics told the experts long ago it was mostly not man-made, Tom Quirk showed that methane rises and falls in time with El Ninos, and was thus largely a natural phenomenon. Willie Soon also pointed out that one of Saturn’s moons has more methane than all the oil and gas deposits on Earth, but has no dinosaurs, cows or leaky wells.

Global Warming Abates in Autumn 2024

Posted on by Ron Clutz

Hot, Hot, Hot.  You will have noticed that the term “climate change” is now synonymous with “summer”.  Since the northern hemisphere is where most of the world’s land, people and media are located, two typical summer months and a hot European August have been depicted as the fires of hell awaiting any and all who benefit from fossil fuels. If you were wondering what the media would do, apart from obsessing over the many small storms this year, you are getting the answer.

Fortunately, Autumn is on the way and already bringing cooler evenings in Montreal where I live. Once again open windows provide fresh air for sleeping, while mornings are showing condensation, and frost sometimes. This year’s period of “climate change” is winding down.  Unless of course, we get some hurricanes the next two months.  Below is a repost of seasonal changes in temperature and climate for those who may have been misled by the media reports of a forever hotter future.

geese-in-v-formation

Autumnal Climate Change

Seeing a lot more of this lately, along with hearing the geese  honking. And in the next week or two we expect that trees around here will lose their leaves. It definitely is climate change of the seasonal variety.

Interestingly, the science on this is settled: It is all due to reduction of solar energy because of the shorter length of days (LOD). The trees drop their leaves and go dormant because of less sunlight, not because of lower temperatures. The latter is an effect, not the cause.

Of course, the farther north you go, the more remarkable the seasonal climate change. St. Petersburg, Russia has their balmy “White Nights” in June when twilight is as dark as it gets, followed by the cold, dark winter and a chance to see the Northern Lights.

And as we have been monitoring, the Arctic ice has been melting from sunlight in recent months, but is already building again in the twilight, to reach its maximum in March under the cover of darkness.

We can also expect in January and February for another migration of millions of Canadians (nicknamed “snowbirds”) to fly south in search of a summer-like climate to renew their memories and hopes. As was said to me by one man in Saskatchewan (part of the Canadian wheat breadbasket region): “Around here we have Triple-A farmers: April to August, and then Arizona.” Here’s what he was talking about: Quartzsite Arizona annually hosts 1.5M visitors, mostly between November and March.

Of course, this is just North America. Similar migrations occur in Europe, and in the Southern Hemisphere, the climates are changing in the opposite direction, Springtime currently. Since it is so obviously the sun causing this seasonal change, the question arises: Does the sunlight vary on longer than annual timescales?

The Solar-Climate Debate

And therein lies a great, enduring controversy between those (like the IPCC) who dismiss the sun as a driver of multi-Decadal climate change, and those who see a connection between solar cycles and Earth’s climate history. One side can be accused of ignoring the sun because of a prior commitment to CO2 as the climate “control knob”.

The other side is repeatedly denounced as “cyclomaniacs” in search of curve-fitting patterns to prove one or another thesis. It is also argued that a claim of 60-year cycles can not be validated with only 150 years or so of reliable data. That point has weight, but it is usually made by those on the CO2 bandwagon despite temperature and CO2 trends correlating for only 3 decades during the last century.

One scientist in this field is Nicola Scafetta, who presents the basic concept this way:

“The theory is very simple in words. The solar system is characterized by a set of specific gravitational oscillations due to the fact that the planets are moving around the sun. Everything in the solar system tends to synchronize to these frequencies beginning with the sun itself. The oscillating sun then causes equivalent cycles in the climate system. Also the moon acts on the climate system with its own harmonics. In conclusion we have a climate system that is mostly made of a set of complex cycles that mirror astronomical cycles. Consequently it is possible to use these harmonics to both approximately hindcast and forecast the harmonic component of the climate, at least on a global scale. This theory is supported by strong empirical evidences using the available solar and climatic data.”

He goes on to say:

“The global surface temperature record appears to be made of natural specific oscillations with a likely solar/astronomical origin plus a noncyclical anthropogenic contribution during the last decades. Indeed, because the boundary condition of the climate system is regulated also by astronomical harmonic forcings, the astronomical frequencies need to be part of the climate signal in the same way the tidal oscillations are regulated by soli-lunar harmonics.”

He has concluded that “at least 60% of the warming of the Earth observed since 1970 appears to be induced by natural cycles which are present in the solar system.” For the near future he predicts a stabilization of global temperature and cooling until 2030-2040. Note that several El Nino spikes have temporarily taken the GMT (Global Mean Temperature) anomaly outside the forecasted bounds.

For more see Scafetta vs. IPCC: Dueling Climate Theories

A more recent Scafetta publication is Reconstruction of the Interannual to Millennial Scale Patterns of the Global Surface Temperature in the journal atmosphere.  There is provided this exhibit comparing his semi-empirical forecast to HadCRUT4

A Deeper, but Accessible Presentation of Solar-Climate Theory

I have found this presentation by Ian Wilson to be persuasive while honestly considering all of the complexities involved.

The author raises the question: What if there is a third factor that not only drives the variations in solar activity that we see on the Sun but also drives the changes that we see in climate here on the Earth?

The linked article is quite readable by a general audience, and comes to a similar conclusion as Scafetta above: There is a connection, but it is not simple cause and effect. And yes, length of day (LOD) is a factor beyond the annual cycle.

It is fair to say that we are still at the theorizing stage of understanding a solar connection to earth’s climate. And at this stage, investigators look for correlations in the data and propose theories (explanations) for what mechanisms are at work. Interestingly, despite the lack of interest from the IPCC, solar and climate variability is a very active research field these days.

For example Svensmark has now a Cosmosclimatology theory supported by empirical studies described in more detail in the red link.

A summary of recent studies is provided at NoTricksZone: Since 2014, 400 Scientific Papers Affirm A Strong Sun-Climate Link

Ian Wilson has much more to say at his blog: http://astroclimateconnection.blogspot.com.au/

Once again, it appears that the world is more complicated than a simple cause and effect model suggests.

 

Fluctuations in observed global temperatures can be explained by a combination of oceanic and solar cycles.  See engineering analysis from first principles Quantifying Natural Climate Change.

For everything there is a season, a time for every purpose under heaven.

Ocean Cooling Resumes September 2024

Posted on by Ron Clutz

The best context for understanding decadal temperature changes comes from the world’s sea surface temperatures (SST), for several reasons:

  • The ocean covers 71% of the globe and drives average temperatures;
  • SSTs have a constant water content, (unlike air temperatures), so give a better reading of heat content variations;
  • Major El Ninos have been the dominant climate feature in recent years.

HadSST is generally regarded as the best of the global SST data sets, and so the temperature story here comes from that source. Previously I used HadSST3 for these reports, but Hadley Centre has made HadSST4 the priority, and v.3 will no longer be updated.  HadSST4 is the same as v.3, except that the older data from ship water intake was re-estimated to be generally lower temperatures than shown in v.3.  The effect is that v.4 has lower average anomalies for the baseline period 1961-1990, thereby showing higher current anomalies than v.3. This analysis concerns more recent time periods and depends on very similar differentials as those from v.3 despite higher absolute anomaly values in v.4.  More on what distinguishes HadSST3 and 4 from other SST products at the end. The user guide for HadSST4 is here.

The Current Context

The chart below shows SST monthly anomalies as reported in HadSST4 starting in 2015 through September 2024.  A global cooling pattern is seen clearly in the Tropics since its peak in 2016, joined by NH and SH cycling downward since 2016, followed by rising temperatures in 2023 and 2024.

Note that in 2015-2016 the Tropics and SH peaked in between two summer NH spikes.  That pattern repeated in 2019-2020 with a lesser Tropics peak and SH bump, but with higher NH spikes. By end of 2020, cooler SSTs in all regions took the Global anomaly well below the mean for this period.  A small warming was driven by NH summer peaks in 2021-22, but offset by cooling in SH and the tropics, By January 2023 the global anomaly was again below the mean.

Now in 2023-24 comes an event resembling 2015-16 with a Tropical spike and two NH spikes alongside. There was also a coinciding rise in SH, and the Global anomaly was pulled up to 1.1°C last year, ~0.3°C higher than the 2015 peak. After several months of cooling in SH and the Tropics, now NH and the Global anomaly resume starting down.

The climatists have seized on this unusual warming as proof their Zero Carbon agenda is needed, without addressing how impossible it would be for CO2 warming the air to raise ocean temperatures.  It is the ocean that warms the air, not the other way around.  Recently Steven Koonin had this to say about the phonomenon confirmed in the graph above:

El Nino is a phenomenon in the climate system that happens once every four or five years.  Heat builds up in the equatorial Pacific to the west of Indonesia and so on.  Then when enough of it builds up it surges across the Pacific and changes the currents and the winds.  As it surges toward South America it was discovered and named in the 19th century  It iswell understood at this point that the phenomenon has nothing to do with CO2.

Now people talk about changes in that phenomena as a result of CO2 but it’s there in the climate system already and when it happens it influences weather all over the world.   We feel it when it gets rainier in Southern California for example.  So for the last 3 years we have been in the opposite of an El Nino, a La Nina, part of the reason people think the West Coast has been in drought.

It has now shifted in the last months to an El Nino condition that warms the globe and is thought to contribute to this Spike we have seen. But there are other contributions as well.  One of the most surprising ones is that back in January of 2022 an enormous underwater volcano went off in Tonga and it put up a lot of water vapor into the upper atmosphere. It increased the upper atmosphere of water vapor by about 10 percent, and that’s a warming effect, and it may be that is contributing to why the spike is so high.

A longer view of SSTs

The graph above is noisy, but the density is needed to see the seasonal patterns in the oceanic fluctuations.  Previous posts focused on the rise and fall of the last El Nino starting in 2015.  This post adds a longer view, encompassing the significant 1998 El Nino and since.  The color schemes are retained for Global, Tropics, NH and SH anomalies.  Despite the longer time frame, I have kept the monthly data (rather than yearly averages) because of interesting shifts between January and July. 1995 is a reasonable (ENSO neutral) starting point prior to the first El Nino. 

The sharp Tropical rise peaking in 1998 is dominant in the record, starting Jan. ’97 to pull up SSTs uniformly before returning to the same level Jan. ’99. There were strong cool periods before and after the 1998 El Nino event. Then SSTs in all regions returned to the mean in 2001-2. 

SSTS fluctuate around the mean until 2007, when another, smaller ENSO event occurs. There is cooling 2007-8,  a lower peak warming in 2009-10, following by cooling in 2011-12.  Again SSTs are average 2013-14.

Now a different pattern appears.  The Tropics cooled sharply to Jan 11, then rise steadily for 4 years to Jan 15, at which point the most recent major El Nino takes off.  But this time in contrast to ’97-’99, the Northern Hemisphere produces peaks every summer pulling up the Global average.  In fact, these NH peaks appear every July starting in 2003, growing stronger to produce 3 massive highs in 2014, 15 and 16.  NH July 2017 was only slightly lower, and a fifth NH peak still lower in Sept. 2018.

The highest summer NH peaks came in 2019 and 2020, only this time the Tropics and SH were offsetting rather adding to the warming. (Note: these are high anomalies on top of the highest absolute temps in the NH.)  Since 2014 SH has played a moderating role, offsetting the NH warming pulses. After September 2020 temps dropped off down until February 2021.  In 2021-22 there were again summer NH spikes, but in 2022 moderated first by cooling Tropics and SH SSTs, then in October to January 2023 by deeper cooling in NH and Tropics.  

Then in 2023 the Tropics flipped from below to well above average, while NH produced a summer peak extending into September higher than any previous year.  Despite El Nino driving the Tropics January 2024 anomaly higher than 1998 and 2016 peaks, following months cooled in all regions, and the Tropics continued cooling in April, May and June along with SH dropping.  After July and August NH warming again pulled the global anomaly higher, September resumed cooling in all regions.

What to make of all this? The patterns suggest that in addition to El Ninos in the Pacific driving the Tropic SSTs, something else is going on in the NH.  The obvious culprit is the North Atlantic, since I have seen this sort of pulsing before.  After reading some papers by David Dilley, I confirmed his observation of Atlantic pulses into the Arctic every 8 to 10 years.

Contemporary AMO Observations

Through January 2023 I depended on the Kaplan AMO Index (not smoothed, not detrended) for N. Atlantic observations. But it is no longer being updated, and NOAA says they don’t know its future.  So I find that ERSSTv5 AMO dataset has current data.  It differs from Kaplan, which reported average absolute temps measured in N. Atlantic.  “ERSST5 AMO  follows Trenberth and Shea (2006) proposal to use the NA region EQ-60°N, 0°-80°W and subtract the global rise of SST 60°S-60°N to obtain a measure of the internal variability, arguing that the effect of external forcing on the North Atlantic should be similar to the effect on the other oceans.”  So the values represent sst anomaly differences between the N. Atlantic and the Global ocean.

The chart above confirms what Kaplan also showed.  As August is the hottest month for the N. Atlantic, its variability, high and low, drives the annual results for this basin.  Note also the peaks in 2010, lows after 2014, and a rise in 2021. Then in 2023 the peak was holding at 1.4C before declining.  An annual chart below is informative:

Note the difference between blue/green years, beige/brown, and purple/red years.  2010, 2021, 2022 all peaked strongly in August or September.  1998 and 2007 were mildly warm.  2016 and 2018 were matching or cooler than the global average.  2023 started out slightly warm, then rose steadily to an  extraordinary peak in July.  August to October were only slightly lower, but by December cooled by ~0.4C.

Now in 2024 the AMO anomaly started higher than any previous year, then leveled off for two months declining slightly into April.  Remarkably, May showed an upward leap putting this on a higher track than 2023, and rising slightly higher in June.  In July, August and September 2024 the anomaly declined and is now lower than the peak reached in 2023.

The pattern suggests the ocean may be demonstrating a stairstep pattern like that we have also seen in HadCRUT4. 

The purple line is the average anomaly 1980-1996 inclusive, value 0.18.  The orange line the average 1980-202404, value 0.39, also for the period 1997-2012. The red line is 2013-202409, value 0.69. As noted above, these rising stages are driven by the combined warming in the Tropics and NH, including both Pacific and Atlantic basins.

Summary

The oceans are driving the warming this century.  SSTs took a step up with the 1998 El Nino and have stayed there with help from the North Atlantic, and more recently the Pacific northern “Blob.”  The ocean surfaces are releasing a lot of energy, warming the air, but eventually will have a cooling effect.  The decline after 1937 was rapid by comparison, so one wonders: How long can the oceans keep this up? And is the sun adding forcing to this process?

Footnote: Why Rely on HadSST4

HadSST is distinguished from other SST products because HadCRU (Hadley Climatic Research Unit) does not engage in SST interpolation, i.e. infilling estimated anomalies into grid cells lacking sufficient sampling in a given month. From reading the documentation and from queries to Met Office, this is their procedure.

HadSST4 imports data from gridcells containing ocean, excluding land cells. From past records, they have calculated daily and monthly average readings for each grid cell for the period 1961 to 1990. Those temperatures form the baseline from which anomalies are calculated.

In a given month, each gridcell with sufficient sampling is averaged for the month and then the baseline value for that cell and that month is subtracted, resulting in the monthly anomaly for that cell. All cells with monthly anomalies are averaged to produce global, hemispheric and tropical anomalies for the month, based on the cells in those locations. For example, Tropics averages include ocean grid cells lying between latitudes 20N and 20S.

Gridcells lacking sufficient sampling that month are left out of the averaging, and the uncertainty from such missing data is estimated. IMO that is more reasonable than inventing data to infill. And it seems that the Global Drifter Array displayed in the top image is providing more uniform coverage of the oceans than in the past.

UAH September 2024: NH Land Up, SH Land Down

Posted on by Ron Clutz

The post below updates the UAH record of air temperatures over land and ocean. Each month and year exposes again the growing disconnect between the real world and the Zero Carbon zealots.  It is as though the anti-hydrocarbon band wagon hopes to drown out the data contradicting their justification for the Great Energy Transition.  Yes, there has been warming from an El Nino buildup coincidental with North Atlantic warming, but no basis to blame it on CO2.  

As an overview consider how recent rapid cooling  completely overcame the warming from the last 3 El Ninos (1998, 2010 and 2016).  The UAH record shows that the effects of the last one were gone as of April 2021, again in November 2021, and in February and June 2022  At year end 2022 and continuing into 2023 global temp anomaly matched or went lower than average since 1995, an ENSO neutral year. (UAH baseline is now 1991-2020). Now we have an usual El Nino warming spike of uncertain cause, unrelated to steadily rising CO2 and now moderating.

For reference I added an overlay of CO2 annual concentrations as measured at Mauna Loa.  While temperatures fluctuated up and down ending flat, CO2 went up steadily by ~60 ppm, a 15% increase.

Furthermore, going back to previous warmings prior to the satellite record shows that the entire rise of 0.8C since 1947 is due to oceanic, not human activity.

gmt-warming-events

The animation is an update of a previous analysis from Dr. Murry Salby.  These graphs use Hadcrut4 and include the 2016 El Nino warming event.  The exhibit shows since 1947 GMT warmed by 0.8 C, from 13.9 to 14.7, as estimated by Hadcrut4.  This resulted from three natural warming events involving ocean cycles. The most recent rise 2013-16 lifted temperatures by 0.2C.  Previously the 1997-98 El Nino produced a plateau increase of 0.4C.  Before that, a rise from 1977-81 added 0.2C to start the warming since 1947.

Importantly, the theory of human-caused global warming asserts that increasing CO2 in the atmosphere changes the baseline and causes systemic warming in our climate.  On the contrary, all of the warming since 1947 was episodic, coming from three brief events associated with oceanic cycles. And now in 2024 we have seen an amazing episode with a temperature spike driven by ocean air warming in all regions, along with rising NH land temperatures, now oscillating near its peak.

Chris Schoeneveld has produced a similar graph to the animation above, with a temperature series combining HadCRUT4 and UAH6. H/T WUWT

September 2024 NH Land Spike Warms More than SH Land Drops

 banner-blog

With apologies to Paul Revere, this post is on the lookout for cooler weather with an eye on both the Land and the Sea.  While you heard a lot about 2020-21 temperatures matching 2016 as the highest ever, that spin ignores how fast the cooling set in.  The UAH data analyzed below shows that warming from the last El Nino had fully dissipated with chilly temperatures in all regions. After a warming blip in 2022, land and ocean temps dropped again with 2023 starting below the mean since 1995.  Spring and Summer 2023 saw a series of warmings, continuing into October, followed by cooling. 

UAH has updated their tlt (temperatures in lower troposphere) dataset for September 2024. Posts on their reading of ocean air temps this month are ahead of the update from HadSST4.  I posted last month on SSTs using NH Pulls Oceans Warmer August 2024.  These posts have a separate graph of land air temps because the comparisons and contrasts are interesting as we contemplate possible cooling in coming months and years.

Sometimes air temps over land diverge from ocean air changes. In July 2024 all oceans were unchanged except for Tropical warming, while all land regions rose slightly. Then in August we saw a warming leap in SH land, slight Land cooling elsewhere, a dip in Tropical Ocean temp and slightly elsewhere. Now in September a dramatic drop in SH land, overcome by a greater NH land increase. End result is an upward bump in Global anomaly.

Note:  UAH has shifted their baseline from 1981-2010 to 1991-2020 beginning with January 2021.  In the charts below, the trends and fluctuations remain the same but the anomaly values changed with the baseline reference shift.

Presently sea surface temperatures (SST) are the best available indicator of heat content gained or lost from earth’s climate system.  Enthalpy is the thermodynamic term for total heat content in a system, and humidity differences in air parcels affect enthalpy.  Measuring water temperature directly avoids distorted impressions from air measurements.  In addition, ocean covers 71% of the planet surface and thus dominates surface temperature estimates.  Eventually we will likely have reliable means of recording water temperatures at depth.

Recently, Dr. Ole Humlum reported from his research that air temperatures lag 2-3 months behind changes in SST.  Thus cooling oceans portend cooling land air temperatures to follow.  He also observed that changes in CO2 atmospheric concentrations lag behind SST by 11-12 months.  This latter point is addressed in a previous post Who to Blame for Rising CO2?

After a change in priorities, updates are now exclusive to HadSST4.  For comparison we can also look at lower troposphere temperatures (TLT) from UAHv6 which are now posted for September.  The temperature record is derived from microwave sounding units (MSU) on board satellites like the one pictured above. Recently there was a change in UAH processing of satellite drift corrections, including dropping one platform which can no longer be corrected. The graphs below are taken from the revised and current dataset.

The UAH dataset includes temperature results for air above the oceans, and thus should be most comparable to the SSTs. There is the additional feature that ocean air temps avoid Urban Heat Islands (UHI).  The graph below shows monthly anomalies for ocean air temps since January 2015.

Note 2020 was warmed mainly by a spike in February in all regions, and secondarily by an October spike in NH alone. In 2021, SH and the Tropics both pulled the Global anomaly down to a new low in April. Then SH and Tropics upward spikes, along with NH warming brought Global temps to a peak in October.  That warmth was gone as November 2021 ocean temps plummeted everywhere. After an upward bump 01/2022 temps reversed and plunged downward in June.  After an upward spike in July, ocean air everywhere cooled in August and also in September.   

After sharp cooling everywhere in January 2023, all regions were into negative territory. Then there is a remarkable spiking of Tropical ocean temps from -0.4 up to + 1.3 in January 2024.  The rise was matched by other regions in 2024 January through May, before dropping lower. Now in September comes an upward bump in NH and Tropics pulling up Global anomaly.

Land Air Temperatures Tracking in Seesaw Pattern

We sometimes overlook that in climate temperature records, while the oceans are measured directly with SSTs, land temps are measured only indirectly.  The land temperature records at surface stations sample air temps at 2 meters above ground.  UAH gives tlt anomalies for air over land separately from ocean air temps.  The graph updated for September is below.

Here we have fresh evidence of the greater volatility of the Land temperatures, along with extraordinary departures by SH land.  Land temps are dominated by NH with a 2021 spike in January,  then dropping before rising in the summer to peak in October 2021. As with the ocean air temps, all that was erased in November with a sharp cooling everywhere.  After a summer 2022 NH spike, land temps dropped everywhere, and in January, further cooling in SH and Tropics offset by an uptick in NH. 

Remarkably, in 2023, SH land air anomaly shot up 2.1C, from  -0.6C in January to +1.5 in September, then dropped sharply to 0.6 in January 2024, matching the SH peak in 2016. Then through May 2024 NH and Tropical land temps spiked to new highs, before dropping down.  Now in August SH land spiked up, then reversed down in September.  NH and Tropics bumped upward, and Global land anomaly rose slightly

The Bigger Picture UAH Global Since 1980

The chart shows monthly Global anomalies starting 01/1980 to present.  The average monthly anomaly is -0.04, for this period of more than four decades.  The graph shows the 1998 El Nino after which the mean resumed, and again after the smaller 2010 event. The 2016 El Nino matched 1998 peak and in addition NH after effects lasted longer, followed by the NH warming 2019-20.   An upward bump in 2021 was reversed with temps having returned close to the mean as of 2/2022.  March and April brought warmer Global temps, later reversed

With the sharp drops in Nov., Dec. and January 2023 temps, there was no increase over 1980. Then in 2023 the buildup to the October/November peak exceeded the sharp April peak of the El Nino 1998 event. It also surpassed the February peak in 2016. In 2024 March and April took the Global anomaly to a new peak of 1.05C.  The cool down started with May dropping to 0.90C, and in June a further decline to 0.80C.  The warming level rose again and has persisted through September.

The graph reminds of another chart showing the abrupt ejection of humid air from Hunga Tonga eruption.

TLTs include mixing above the oceans and probably some influence from nearby more volatile land temps.  Clearly NH and Global land temps have been dropping in a seesaw pattern, nearly 1C lower than the 2016 peak.  Since the ocean has 1000 times the heat capacity as the atmosphere, that cooling is a significant driving force.  TLT measures started the recent cooling later than SSTs from HadSST4, but are now showing the same pattern. Despite the three El Ninos, their warming had not persisted prior to 2023, and without them it would probably have cooled since 1995.  Of course, the future has not yet been written.

 

NH Pulls Oceans Warmer August 2024

Posted on by Ron Clutz

The best context for understanding decadal temperature changes comes from the world’s sea surface temperatures (SST), for several reasons:

  • The ocean covers 71% of the globe and drives average temperatures;
  • SSTs have a constant water content, (unlike air temperatures), so give a better reading of heat content variations;
  • Major El Ninos have been the dominant climate feature in recent years.

HadSST is generally regarded as the best of the global SST data sets, and so the temperature story here comes from that source. Previously I used HadSST3 for these reports, but Hadley Centre has made HadSST4 the priority, and v.3 will no longer be updated.  HadSST4 is the same as v.3, except that the older data from ship water intake was re-estimated to be generally lower temperatures than shown in v.3.  The effect is that v.4 has lower average anomalies for the baseline period 1961-1990, thereby showing higher current anomalies than v.3. This analysis concerns more recent time periods and depends on very similar differentials as those from v.3 despite higher absolute anomaly values in v.4.  More on what distinguishes HadSST3 and 4 from other SST products at the end. The user guide for HadSST4 is here.

The Current Context

The chart below shows SST monthly anomalies as reported in HadSST4 starting in 2015 through August 2024.  A global cooling pattern is seen clearly in the Tropics since its peak in 2016, joined by NH and SH cycling downward since 2016, followed by rising temperatures in 2023 and 2024.

Note that in 2015-2016 the Tropics and SH peaked in between two summer NH spikes.  That pattern repeated in 2019-2020 with a lesser Tropics peak and SH bump, but with higher NH spikes. By end of 2020, cooler SSTs in all regions took the Global anomaly well below the mean for this period.  

Then in 2022, another strong NH summer spike peaked in August, but this time both the Tropic and SH were countervailing, resulting in only slight Global warming, later receding to the mean.   Oct./Nov. temps dropped  in NH and the Tropics took the Global anomaly below the average for this period. After an uptick in December, temps in January 2023 dropped everywhere, strongest in NH, with the Global anomaly further below the mean since 2015.

Then came El Nino as shown by the upward spike in the Tropics since January 2023, the anomaly nearly tripling from 0.38C to 1.09C.  In September 2023, all regions rose, especially NH up from 0.70C to 1.41C, pulling up the global anomaly to a new high for this period. By December, NH cooled to 1.1C and the Global anomaly down to 0.94C from its peak of 1.10C, despite slight warming in SH and Tropics.

In January 2024 both Tropics and SH rose, resulting in Global Anomaly going higher. Since then Tropics have cooled from a  peak of 1.29C down to 0.84C.  SH also dropped down from 0.89C to 0.65C. NH lost ~0.4C as of March 2024, but has risen 0.2C over April to June. Despite that upward NH bump, the Global SST anomaly cooled further. 

In July there was a warming uptick in all regions, and now in August a new high in NH, along with the Tropics, bringing the global anomaly up to almost match August 2023. We have now three distinct warmings: the El Nino driven peak in 2025-16, the lesser peak in 2019-20 and now a stronger warming event in 2023-24.

HadSST4 imports data from gridcells containing ocean, excluding land cells. From past records, they have calculated daily and monthly average readings for each grid cell for the period 1961 to 1990. Those temperatures form the baseline from which anomalies are calculated.

In a given month, each gridcell with sufficient sampling is averaged for the month and then the baseline value for that cell and that month is subtracted, resulting in the monthly anomaly for that cell. All cells with monthly anomalies are averaged to produce global, hemispheric and tropical anomalies for the month, based on the cells in those locations. For example, Tropics averages include ocean grid cells lying between latitudes 20N and 20S.

Gridcells lacking sufficient sampling that month are left out of the averaging, and the uncertainty from such missing data is estimated. IMO that is more reasonable than inventing data to infill. And it seems that the Global Drifter Array displayed in the top image is providing more uniform coverage of the oceans than in the past.

Fatal Flaw Discredits IPCC Science

Posted on by Ron Clutz

By way of John Ray comes this Spectator Australia article A basic flaw in IPCC science.  Excerpts in italics with my bolds and added images.

Detailed research is underway that threatens to undermine the foundations of the climate science promoted by the IPCC since its First Assessment Report in 1992. The research is re-examining the rural and urban temperature records in the Northern Hemisphere that are the foundation for the IPCC’s estimates of global warming since 1850. The research team has been led by Dr Willie Soon (a Malaysian solar astrophysicist associated with the Smithsonian Institute for many years) and two highly qualified Irish academics – Dr Michael Connolly and his son Dr Ronan Connolly. They have formed a climate research group CERES-SCIENCE. Their detailed research will be a challenge for the IPCC 7th Assessment Report due to be released in 2029 as their research results challenge the very foundations of IPCC science.

The climate warming trend published by the IPCC is a continually updated graph based on the temperature records of Northern Hemisphere land surface temperature stations dating from the mid 19th Century. The latest IPCC 2021 report uses data for the period 1850-2018. The IPCC’s selection of Northern Hemisphere land surface temperature records is not in question and is justifiable. The Northern Hemisphere records provide the best database for this period. The Southern Hemisphere land temperature records are not that extensive and are sparse for the 19th and early 20th Century. It is generally agreed that the urban temperature data is significantly warmer than the rural data in the same region because of an urban warming bias. This bias is due to night-time surface radiation of the daytime solar radiation absorbed by concrete and bitumen. Such radiation leads to higher urban night-time temperatures than say in the nearby countryside. The IPCC acknowledges such a warming bias but alleges the increased effect is only 10 per cent and therefore does not significantly distort its published global warming trend lines.


Since 2018, Dr Soon and his partners have analysed the data from rural and urban temperature recording stations in China, the USA, the Arctic, and Ireland. The number of stations with reliable temperature records in these areas increased from very few in the mid-19th Century to around 4,000 in the 1970s before decreasing to around 2,000 by the 1990s. The rural temperature recording stations with good records peaked at 400 and are presently around 200.

Their analysis of individual stations needs to account for any variation in their exposure to the Sun due to changes in their location, OR shadowing due to the construction of nearby buildings, OR nearby vegetation growth. The analysis of rural temperature stations is further complicated as over time many are encroached by nearby cities. Consequently, the data from such stations needs to be shifted at certain dates from the rural temperature database to either an intermediate database or to a full urban database. Consequently, an accurate analysis of the temperature records of each recording station is a time-consuming task.


This new analysis of 4,000 temperature recording stations in China, the USA, the Arctic, and Ireland shows a warming trend of 0.89ºC per century in the urban stations that is 1.61 times higher that a warming trend of 0.55ºC per century in the rural stations. This difference is far more significant than the 10 per cent divergence between urban and rural stations alleged in the IPCC reports; a divergence explained by a potential flaw in the IPCC’s methodology. The IPCC uses a technique called homogenisation that averages the rural and urban temperatures in a particular region. This method distorts the rural temperature records as over 75 per cent of the temperature records used in this homogenisation methodology are urban stations. So, a methodology that attempts to statistically identify and correct some biases that may be in the raw data, in effect, leads to an urban blending of the rural dataset. This result is biased as it downgrades the actual values of each rural temperature station. In contrast, Dr Soon and his coworkers avoided homogenisation so the temperature trends they identify for each rural region are accurate as the rural data are not distorted by the readings from nearby urban stations.


The rural temperature trend measured by this new research is 0.55ºC per century and it indicates the Earth has warmed 0.9ºC since 1850. In contrast, the urban temperature trend measured by this new research is 0.89ºC per century and indicates a much higher warming of 1.5ºC since 1850. Consequently, a distorted urban warming trend has been used by the IPCC to quantify the warming of the whole of the Earth since 1850. The exaggeration is significant as the urban temperature record database used by the IPCC only represents the temperatures on 3-4 per cent of the Earth’s land surface area; an area less than 2 per cent of the Earth’s total surface area. During the next few years, Dr Willie Soon and his research team are currently analysing the meta-history of 800 European temperature recording stations. When this is done their research will be based on very significant database of Northern Hemisphere rural and urban temperature records from China, the USA, the Arctic, Ireland, and Europe.

This new research has unveiled another flaw in the IPCC‘s temperature narrative as trend lines in its revised temperature datasets are different from those published by the IPCC. For example, the rural records now show a marked warming trend in the 1930s and 1940s while there is only a slight warming trend in the IPCC dataset. The most significant difference is the existence of a marked cooling period in the rural dataset for the 1960s and 1970s that is almost absent in the IPCC’s urban dataset. This later divergence upsets the common narrative that rising carbon dioxide levels control modern warming trends. For, if carbon dioxide levels are the driver of modern warming, how can a higher rate of increasing carbon dioxide levels exist within a cooling period in the 1960s and 1970s while a lower increasing rate of carbon dioxide levels coincides with an earlier warming interval in the 1930s and 1940s? Or, in other words, how can carbon dioxide levels increasing at 1.7 parts per million per decade cause a distinct warming period in the 1930s and 1940s while a larger increasing rate of 10.63 parts per million per decade is associated with a distinct cooling period in the 1960s and 1970s! Consequently, the research of Willie Soon and his coworkers is discrediting, not only the higher rate of global warming trends specified in IPCC Reports, but also the theory that rising carbon dioxide levels explain modern warming trends; a lynchpin of IPCC science for the last 25 years.

Willie Soon and his coworkers maintain that climate scientists need to consider other possible explanations for recent global warming. Willie Soon and his coworkers point to the Sun, but the IPCC maintains that variations in Total Solar Irradiance (TSI) are over eons and not over shorter periods such as the last few centuries. For that reason, the IPCC point to changes in greenhouse gases as the most obvious explanation for global warming since 1850. In contrast, Willie Soon and his coworkers maintain there can be short-term changes in solar activity and, for example, refer to a period of no sunspot activity that coincided with the Little Ice Age in the 17th Century. They also point out there is still no agreed average figure for Total Solar Irradiance (TSI) despite 30 years of measurements taken by various satellites. Consequently, they contend research in this area is not settled.

The CERES-SCIENCE research project pioneered by Dr Willie Soon and the father-son Connolly team has questioned the validity of the high global warming trends for the 1850-present period that have been published by the IPCC since its first report in 1992. The research also queries the IPCC narrative that rising greenhouse gas concentrations, particularly carbon dioxide, are the primary driver of global warming since 1850. That narrative has been the foundation of IPCC climate science for the last 40 years. It will be interesting to see how the IPCC’s 7th Assessment Report in 2029 treats this new research that questions the very basis of IPCC’s climate science.

The paper is The Detection and Attribution of Northern Hemisphere Land Surface Warming (1850–2018) in Terms of Human and Natural Factors: Challenges of Inadequate Data. 

Abstract

A statistical analysis was applied to Northern Hemisphere land surface temperatures (1850–2018) to try to identify the main drivers of the observed warming since the mid-19th century. Two different temperature estimates were considered—a rural and urban blend (that matches almost exactly with most current estimates) and a rural-only estimate. The rural and urban blend indicates a long-term warming of 0.89 °C/century since 1850, while the rural-only indicates 0.55 °C/century. This contradicts a common assumption that current thermometer-based global temperature indices are relatively unaffected by urban warming biases.

Three main climatic drivers were considered, following the approaches adopted by the Intergovernmental Panel on Climate Change (IPCC)’s recent 6th Assessment Report (AR6): two natural forcings (solar and volcanic) and the composite “all anthropogenic forcings combined” time series recommended by IPCC AR6. The volcanic time series was that recommended by IPCC AR6. Two alternative solar forcing datasets were contrasted. One was the Total Solar Irradiance (TSI) time series that was recommended by IPCC AR6. The other TSI time series was apparently overlooked by IPCC AR6. It was found that altering the temperature estimate and/or the choice of solar forcing dataset resulted in very different conclusions as to the primary drivers of the observed warming.

Our analysis focused on the Northern Hemispheric land component of global surface temperatures since this is the most data-rich component. It reveals that important challenges remain for the broader detection and attribution problem of global warming: (1) urbanization bias remains a substantial problem for the global land temperature data; (2) it is still unclear which (if any) of the many TSI time series in the literature are accurate estimates of past TSI; (3) the scientific community is not yet in a position to confidently establish whether the warming since 1850 is mostly human-caused, mostly natural, or some combination. Suggestions for how these scientific challenges might be resolved are offered.

Climate Policies Built on CO2 Deceptions

Posted on by Ron Clutz

From response by James Matkin  Former Deputy Minister at Government of British Columbia to Quora question What are the criticisms of the Canadian federal carbon pricing system implemented under the Trudeau government’s “Pan-Canadian Framework” on climate change?  Excerpts in italics with my bolds.

The big lie is that Canada needs more carbon dioxide, not less, which is the intent of the carbon tax. Also, there is no carbon pricing system; rather, there is a carbon dioxide pricing system. Carbon is not the equivalent of CO2.

We need less carbon pollution from coal and more
carbon dioxide for our health and well-being.

This mistaken terminology deceives the public as it portends pollution. Amazingly, US President Obama, Trudeau, and Kamala Harris falsely call CO2 carbon pollution.

CO2 is used to save premature babies in incubators.

CO2 is the primary gas for fire extinguishers.

The solid form of CO2 is dry ice not carbon.
Likewise the solid form of H2O is ice not hydrogen.

More CO2 has enormous benefits for crops and our health. It also greens deserts and saves fresh water by spurring tree growth.

If CO2 was a problem why does the commercial greenhouse industry infuse up to 1500 ppm 7/24 to increase plant growth?

Canadians pay an imposing Carbon Tax to save the planet, while the rest of North America has no such Carbon Tax. If you look at economics, the Carbon Tax lowered our standard of living and did nothing for Climate Change.

Canada is a foolish outlier that punishes citizens with a carbon tax to harm plant growth, hospital surgeries, and water retention and cause inflation making the poor poorer.

Canadian emissions of CO2 by fossil fuels are only < 5% of natural
CO2 sources which are too tiny to matter if CO2 mattered to the climate, which it doesn’t.

The driving forces of climate change are natural
not human emissions of CO2

The UN claim that human industry Co2 emissions are causing runaway global warming that will end in catastrophe if not arrested with renewables and carbon taxes was only a thought experiment without any physical observation. Think about this – the UN said there was no historical precedent for the rapid rise in temperatures after industrialization therefore increased CO2 must be the culprit. This is both false logic and untrue. A raft of studies about temperature variability from ocean currents or changes in solar cycles evident in rising or falling sunspots easily explains the temperature rise.

Today with the benefit of hindsight there never was any fast rising temperatures needing explanation. In fact temperature’s rise of less than 1 °C over the past 140 years and now falling 0.4 °C in the past three years means no global warming now or in the past.

Because the climate changes over a long period of time no one living or dead has actually looked out the window and observed climate change. You see weather and it may be a heat wave, snow storm or record rainfall, but one weather event is never a new pattern of changing weather because that must be a statistical analysis.

Beware “Fact Checking” by Innuendo

Posted on by Ron Clutz

Kip Hansen gives the game away in his Climate Realism article Illogically Facts —’Fact-Checking’ by Innuendo.  Excerpts in italics with my bolds and added images.

The latest fad in all kinds of activism to attack one’s ideological opponents via “fact checking”.    We see this in politics and all the modern controversies, including, of course, Climate Science.

Almost none of the “fact checking sites” and “fact checking organizations” actually check facts.  And, if they accidentally find themselves checking what we would all agree is a fact, and not just an opinion or point of view, invariably it is checked against an contrary opinion, a different point of view or an alternative fact.

The resulting fact check report depends on the purposes of the fact check.  Some are done to confirm that “our guy” or “our team” is proved to be correct, or that the opposition is proved to be wrong, lying or misinformation.  When a fact is found to be different in any way from the desired fact, even the tiniest way, the original being checked is labelled a falsehood, or worse, an intentional lie. (or conversely, other people are lying about our fact!).   Nobody likes a liar, so this sort of fake fact checking accomplishes two goals – it casts doubt on the not-favored fact supposedly being checked and smears an ideological opponent as a liar.  One stone – two birds.

While not entirely new on the fact-checking scene, an AI-enhanced effort has popped to the surface of the roiling seas of controversy: Logically Facts.  “Logically Facts is part of Meta’s Third Party Fact-Checking Program (3PFC) and works with TikTok in Europe. We have been a verified signatory of the International Fact-Checking Network (IFCN) since 2020 and are a member of the Misinformation Combat Alliance (MCA) in India and the European Digital Media Observatory (EDMO) in Europe.” [ source ]   Meta? “Meta Platforms…is the undisputed leader in social media. The technology company owns three of the four biggest platforms by monthly active users (Facebook, WhatsApp, and Instagram).” “Meta’s social networks are known as its Family of Apps (FoA). As of the fourth quarter of 2023, they attracted almost four billion users per month.”   And TikTok?  It has over a billion users.

I’m doubting that one can add up the 4 billion and the 1 billion to make 5 billion users of META and TikTok combined, but in any case, that’s a huge percentage of humanity any way one looks at it.

And who is providing fact-checking to those billion of people?  Logically Facts [LF].

And what kind of fact-checking does LF do?  Let’s look at an example that will deal with something very familiar with readers here:  Climate Science Denial.

The definition put forward by the Wiki is:

“Climate change denial (also global warming denial) is a form of science denial characterized by rejecting, refusing to acknowledge, disputing, or fighting the scientific consensus on climate change.”

Other popular definitions of climate change denial include: attacks on solutions, questioning official climate change science and/or the climate movement itself.

If I had all the time left to me in this world, I could do a deep, deep dive into the Fact-Checking Industry.  But, being limited, let’s look, together, at one single “analysis” article from Logically Facts:

‘Pseudoscience, no crisis’: How fake experts are fueling climate change denial

This article is a fascinating study in “fake-fact-checking by innuendo”. 

As we go through the article, sampling its claims, I’ll alert you to any check of an actual fact – don’t hold your breath.   If you wish to be pro-active, read the LF piece first, and you’ll have a better handle on what they are doing.

The lede in their piece is this:

“Would you seek dental advice from an ophthalmologist? The answer is obvious. Yet, on social media, self-proclaimed ‘experts’ with little to no relevant knowledge of climate science are influencing public opinion.” 

The two editors of this “analysis” are listed as Shreyashi Roy [MA in Mass Communications and a BA in English Literature] and Nitish Rampal [ … based out of New Delhi and has …. a keen interest in sports, politics, and tech.]  The author is said to be [more on “said to be” in a minute…] Anurag Baruah [MA in English Language and a certificate in Environmental Journalism: Storytelling earned online from the Thompson Founation.]

Why do you say “said to be”, Mr. Hansen?  If you had read the LF piece, as I suggested, you would see that it reads as if it was “written” by an AI Large Language Model, followed by editing for sense and sensibility by a human, probably, Mr. Baruah, followed by further editing by Roy and Rampal.

The lede is itself an illogic.  First it speaks of medical/dental advice, pointing out, quite rightly, that they are different specializations.  But then complains that unnamed so-called self-proclaimed experts who LF claims “have little to no relevant knowledge of climate science” are influencing public opinion.   Since these persons are so-far unnamed, LF’s AI, author and subsequent editors could not possibly know what their level of knowledge about climate science might be.

Who exactly are they smearing here?

The first is:

“One such ‘expert,’ Steve Milloy, a prominent voice on social media platform X (formerly Twitter), described a NASA Climate post (archive) about the impact of climate change on our seas as a “lie” on June 26, 2024.”

It is absolutely true that Milloy, who is well-known to be an “in-your-face” and “slightly over the-top” critic of all things science that he considers poorly done, being over-hyped, or otherwise falling into his category of “Junk Science”, posted on X the item claimed. 

LF , its AI, author and editors make no effort to check what fact/facts
Milloy was calling a lie, or to check NASA’s facts in any way whatever.

You see, Milloy calling any claim from NASA “a lie” would be an a priori case of Climate Denial: he is refuting or refusing to accept some point of official climate science.

Who is Steve Milloy? 

Steve Milloy is a Board Member & Senior Policy Fellow of the Energy and Environment Legal Institute, author of seven books and over 600 articles/columns published in major newspapers, magazines and internet outlets.  He has testified by request before the U.S. Congress many times, including on risk assessment and Superfund issues.  He is an Adjunct Fellow of the National Center for Public Policy Research.

“He holds a B.A. in Natural Sciences, Johns Hopkins University; Master of Health Sciences (Biostatistics), Johns Hopkins University School of Hygiene and Public Health; Juris Doctorate, University of Baltimore; and Master of Laws (Securities regulation) from the Georgetown University Law Center.”

It seems that many consider Mr. Milloy to be an expert in many things.

And the evidence for LF’s dismissal of Milloy as a “self-proclaimed expert”  having “little to no relevant knowledge of climate science”?  The Guardian, co-founder of the climate crisis propaganda outfit Covering Climate Now, said “JunkScience.com, has been called “the main entrepôt for almost every kind of climate-change denial”” and after a link listing Milloy’s degrees, pooh-poohed him for “lacking formal training in climate science.”  Well, a BA in Natural Sciences might count for something. And a law degree is not nothing. The last link which gives clear evidence that Milloy is a well-recognized expert and it is obvious that the LF AI, author, and editors either did not read the contents of the link or simply chose to ignore it.

Incredibly, LF’s next target is “… John Clauser, a 2022 Nobel Prize winner in physics, claimed that no climate crisis exists and that climate science is “pseudoscience.” Clauser’s Nobel Prize lent weight to his statements, but he has never published a peer-reviewed paper on climate change.“

LF’s evidence against Clauser is The Washington Post in an article attacking not just Clauser, but a long list of major physicists who do not support the IPCC consensus on climate change:  Willie Soon (including the lie that Soon’s work was financed by fossil fuel companies) , Steve Koonin, Dick Lindzen and Will Happer.   The Post article fails to discuss any of the reasons these esteemed, world-class physicists are not consensus-supporting club members. 

Their non-conforming is their crime.  No facts are checked.

LF reinforces the attack on world-renown physicists with a quote from Professor Bill McGuire:  “Such fake experts are dangerous and, in my opinion, incredibly irresponsible—Nobel Prize or not. A physicist denying anthropogenic climate change is actually denying the well-established physical properties of carbon dioxide, which is simply absurd.”

McGuire, is not a physicist and is not a climate scientist, but has a PhD in Geology and is a volcanologist and an IPCC contributor.   He also could be seen as “lacking formal training in climate science.”

But, McGuire has a point, which LF, its AI and its human editors seem to miss, the very basis of the CO2 Global Warming hypothesis is based on physics, not based on what is today called “climate science”. Thus, the physicists are the true experts . (and not the volcanologists….)

LF then launches into the gratuitous comparison of “fake experts” in the anti-tobacco fight, alludes to oil industry ties, and then snaps right to John Cook.

John Cook, a world leader in attacking Climate Change Denial, is not a climate scientist.  He is not a geologist, not an atmospheric scientist, not an oceanic scientist, not a physicist, not even a volcanologist.   He  “earned his PhD in Cognitive Science at the University of Western Australia in 2016”.

The rest of the Logically Facts fake-analysis is basically a re-writing of some of Cook’s anti-Climate Denialists screeds.  Maybe/probably resulting from an AI large language model trained on pro-consensus climate materials.  Logically Facts is specifically and openly an AI-based effort.

LF proceeds to attack a series of persons, not their ideas, one after another:  Tony Heller, Dr. Judith Curry, Patrick Moore and Bjørn Lomborg.

The expertise of these individuals in their respective fields
are either ignored or brushed over.

Curry is a world renowned climate scientist, former chair of the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology.  Curry is the author the book on Thermodynamics of Atmospheres and Oceans, another book on Thermodynamics, Kinetics, and Microphysics of Clouds, and the marvelous groundbreaking Climate Uncertainty and Risk: Rethinking Our Response.  Google scholar returns over 10,000 references to a search of “Dr. Judith Curry climate”.

Lomborg is a socio-economist with an impressive record, a best selling author and a leading expert on issues of energy dependence, value for money spent on international anti-poverty and public health efforts, etc.   Richard Tol, is mention negatively for daring to doubt the “97% consensus”, with no mention of his qualifications as a Professor of Economics and a Professor of the Economics of Climate Change.

Bottom Line:

Logically Facts is a Large Language Model-type AI, supplemented by writers and editors meant to clean-up the mess returned by this chat-bot type AI.    Thus, it is entirely incapable to making any value judgements between repeated slander, enforced consensus views, the prevailing biases of scientific fields and actual facts.  Further, any LLM-based AI is incapable of Critical Thinking and drawing logical conclusions.

In short, Logically Facts is Illogical.
