Natural Gas Industry’s Smear of Coal Is False and Self-Defeating

by G. Wrightstone, July 22, 2024 in RealClearEnergy

Smearing coal has become a marketing strategy of a natural gas industry that embraces pseudoscientific views of coal combustion as being hazardous.

In so doing, gas supporters give credence to a fallacious regulatory regime of the Environmental Protection Agency (EPA), which erroneously classifies carbon dioxide as a pollutant and assigns health effects to low-level pollution without scientific proof. To boot, a false representation of coal, oil and natural gas as environmental bogeymen is perpetuated.

Perhaps the most enthusiastic user of this foolish ploy is Toby Rice, CEO of Pittsburgh-based EQT Corp., who introduced two years ago a global plan to replace coal with liquefied natural gas. Promoting his product as a “decarbonizing force” in June at a RealClearEnergy conference, the head of the country’s largest gas producer (check the video link above to see his part), said:

“What we would like to do at EQT … is focus people on a really practical solution that will allow us to provide energy security for the world and address people’s concerns over global emissions. And that path is very simple: transition the world from coal to gas.”

Although natural gas emits less carbon dioxide than coal when burned, the underlying premise of Rice’s pitch rests on the popular myth that CO2 emissions will overheat the planet. The organization we lead, the CO2 Coalition, has overwhelming evidence from top scientists showing that increasing atmospheric carbon dioxide not only poses no danger but is beneficial to plant growth and crop production.

The ‘Climate Emergency’ is a Myth, Says Nobel Prize Winner John Clauser. Here’s Why He’s Right

by Dr R. Kalveks, June 8, 2024 in DailySceptic

In a recent lecture, Nobel Laureate physicist John Clauser exposed how the Intergovernmental Panel on Climate Change (IPCC) models and analyses, which are relied upon by politicians and activists to support claims of a ‘climate crisis’, do not meet basic standards of scientific enquiry. Clauser received his Nobel prize in 2022 for the observational measurement of quantum entanglement and understands well the problem of distinguishing a physical signal from background noise.

Clauser shows that, when corrected for the IPCC’s error prone arithmetic and statistics, the observational data do not support the power imbalance claimed to be responsible for global warming. Furthermore, the outputs of climate models are at variance with the observational record. Clauser discusses the roles of convection, clouds and their variability in providing a negative feedback mechanism, and proposes that this acts as a thermostat that stabilises surface temperatures. Clauser’s conclusion is that claims of a ‘climate crisis’ lack scientific substance and that Net Zero policies are an unnecessary hindrance.

Energy Flows in the Climate System

It is useful to start with a simplified depiction of the solar energy flow that reaches the Earth, its transformation by the Earth’s climate system and the resulting (mostly thermal) energy flow that leaves the Earth’s atmosphere. This is shown in Figure 1, taken from a recent IPCC report.

The IPCC diagram shows an energy imbalance, being the difference between the incoming visible and UV solar radiation 340 W/m2, less the amount reflected (100 W/m2), less the outgoing infra-red (IR) thermal radiation (239 W/m2). The claimed imbalance at the Top of the Atmosphere is 0.7 W/m2 (give or take 0.2) and the IPCC asserts that this is driving the continuing warming of the climate system.

Table. 1. Top of Atmosphere Energy Flows. Energy flows at the top of the Earth’s atmosphere, with their errors as per Figure 1. The balance is calculated from its components.

The radiation measurements necessary for this calculation are carried out at different wavelengths by instruments carried by satellites, and observational errors are inevitable. Combining the uncertainty ranges in the incoming, reflected and outgoing streams shown in Table 1, by using the standard statistical Root Mean Square rule, shows that the error margin in the calculated imbalance is actually 3 W/m2, some 15 times greater than the 0.2 W/m2 error margin claimed by the IPCC. In short, there is no observedenergy imbalance. The claimed imbalance of 0.7 W/m2 is swamped by observational error, and, from a scientific perspective, it is described by Clauser as a “fudge”.

Carbon Dioxide and a Warming Climate are not problems

by A. May & M. Crok, May 29, 2024 in AmJEconSociology

Dear signatories of the Clintel World Climate Declaration

 

We are very excited to announce the publication of our peer reviewed paper titled “Carbon dioxide and a warming climate are not problems“. It was published in the American Journal of Economics and Sociology. The paper was written by Andy May, retired petrophysicist and currently climate writer and blogger, and Clintel director Marcel Crok.

Crok and May coordinated the ambitious Clintel project to analyse the IPCC AR6 report, which last year led to the publication of the Clintel book The Frozen Climate Views of the IPCC. In the book we document serious errors and biases in the latest IPCC report.
The new paper is largely based on the many interesting findings of that book.

The new paper gets a lot of attention, mostly positive and some critical (of course). This has led to an impressive attention score (which gives an indication of how much the paper is being discussed on blogs and on X/twitter). The paper is already in the 99th percentile.

 

It was a little expensive (2330 euros) to make the paper open access so we decided not to do that this time. But our submitted version can be downloaded for free.

Signatories of the World Climate Declaration could help us boosting the paper even further by writing about it on blogs and/or discussing the paper on X (twitter).

Andy May has been responding very promptly to some of the criticism on the paper, see here, here and here.

Peer reviewed skepticism

by D. Wojick, July 9, 2024 in WUWT

A fine skeptical journal article waded through green pal review. Wonder of wonders!

The journal is the American Journal of Economics and Sociology. The article title is perfectly clear: “Carbon dioxide and a warming climate are not problems”.

See https://onlinelibrary.wiley.com/doi/10.1111/ajes.12579

But it is an “Early View Online Version of Record before inclusion in an issue” so get it before it gets too hot for the Journal. I understand it is very popular so the green screams are deafening.

Alas it is paywalled but the lengthy free Abstract is as clear as the title. Here is the conclusion:

“Observations show no increase in damage or any danger to humanity today due to extreme weather or global warming (Crok & May,  2023, pp. 140–161; Scafetta,  2024). Climate change mitigation, according to AR6, means curtailing the use of fossil fuels, even though fossil fuels are still abundant and inexpensive. Since the current climate is arguably better than the pre-industrial climate and we have observed no increase in extreme weather or climate mortality, we conclude that we can plan to adapt to any future changes. Until a danger is identified, there is no need to eliminate fossil fuel use.”

The authors are Andy May and Marcel Crok and as the first parenthetical reference above indicates they are building on prior work. Their 53 References are not paywalled and quite interesting. Continuer la lecture de Peer reviewed skepticism →

Media Reports Earth’s ‘1.5C Temperature limit’ was ‘breached for 12 months in a row’ – Nothing Bad Happened

by A. Watts, July 10, 2024 in WUWT

Originally posted at ClimateREALISM

Recently, several media outlets claimed that June 2024 was the hottest June on record globally and that it topped off a string of 12 or 13 warmer than normal months, which they blamed on human-induced climate change. Each of the news stories made false claims of reaching climate tipping points, extreme weather events, and that the extended streak of hot temperatures proved a “climate crisis” was at hand.

Here are some of the headlines: Temperatures 1.5C above pre-industrial era average for 12 months, data shows (The Guardian,) June sizzled to a 13th straight monthly heat record, but July might break string (National Public Radio,) and World in line for hottest year as 1.5C limit breached for 12 months in a row (Financial Times.)

That ongoing 1.5C temperature limit scare-story has people around the world rattled. For example, this infographic from The Asia-Pacific branch of the International Union of Food workers (IUF) says (bold author’s):

Global warming caused by human activities reached approximately 1°C over the past 170 years, increasing at 0.2°C per decade. Scientists warn that an average rise of more than 1.5°C in the surface temperature of the earth compared to pre-industrial levels will be catastrophic for the environment and human health.

But despite 12 months of the globe being above the so-called temperature limit, nothing bad happened on a global scale. Claims of climate catastrophe once we passed the so-called 1.5C temperature limit, never happened. The limit was nothing more than a political talking point from the 2015 Paris Climate Conference, as described in this Associated Press article: The magic 1.5: What’s behind climate talks’ key elusive goal. The AP wrote, “in a way both the ‘1.5 and 2 degree C thresholds are somewhat arbitrary,’ Stanford University climate scientist Rob Jackson said in an email. ‘Every tenth of a degree matters!’”

Now, despite surpassing that arbitrary limit, the “crisis” progressive politicians and alarmists in the mainstream media have been warning about failed to materialize.

First let’s check the global temperature. The source of all these news stories comes from a recent press release by Copernicus, part of the European Commission. A graph by Copernicus, seen in Figure 1 below, illustrates the “limit” and the 12-month temperature peak:

Climate Activists Are Wrong About Which Energy Source Reduces Air Pollution

by S. Graham, June 20, 2024 in WUWT

oday’s media are filled with concerns about air pollution. But few people know which energy source has produced the greatest modern reduction in air pollution. The answer isn’t wind or solar energy.

During the 1950s, my grandfather had a coal furnace in his basement, like many homes in Chicago. Five days after a winter snowfall, the snow was covered with a visible black film of dust from coal furnaces. Our younger generation does not know the original reason for “spring cleaning.” Every spring, homeowners would wash their inside walls to remove coal dust.

It was the rising use of gas fuel, primarily natural gas along with propane, that produced the greatest reduction in air pollution in the United States and across the world. Gas furnaces and stoves have replaced wood in businesses and homes in developed nations. And natural gas power plants have replaced coal-fired plants to generate electricity, with gas becoming the leading fuel for industry.

Natural gas and propane are clean-burning fuels that emit no harmful pollutants when burned. When gas heating is substituted for coal or wood heating, indoor particulate pollution is reduced by 1,000 times.

Today, 70% of US homes use natural gas or propane, a percentage that has been rising for decades. Gas fuels have also become the leading heating and cooking source in Europe, providing 83% of heat energy in the Netherlands and 78% in the United Kingdom. But there are still 70 million wood stoves in Europe.

The World Health Organization estimates that 2 billion people in developing nations still cook using open fires or inefficient stoves fueled by kerosene, biomass (wood, charcoal, animal dung, or crop waste), and coal. These fuels generate harmful indoor air pollution. Indoor air pollution is estimated to cause more than 3 million deaths annually in poor nations. Emerging nations need gas fuels to boost health and well-being.

Olympics 2024: how extreme weather could impact Paris games

by S. King, , June 18 2024, BBC

The summer Olympics and Paralympic games in Paris are just over a month away and there is concern about the potential effects of extreme heat.

Some parts of Europe have already registered temperatures over 40C and it is not unreasonable to suggest that elsewhere in Europe will experience heatwaves in the coming months.

In a report published on Tuesday, Lord Coe, President of World Athletics, says “climate change should increasingly be viewed as an existential threat to sport”.

Intense heat could affect the events, competitors, spectators and officials.

Changing climate of Paris

We don’t know what the forecast will be for Paris during the Olympic period, but Meteo France – the national weather service – has said that summer is likely to be warmer than average.

France has experienced deadly summer heatwaves in the past.

The highest recorded temperature in Paris is 42.6C set at the end of July 2019.

And more recently in 2022, during the Olympic period, a lengthy heatwave saw maximum temperatures reach 36C.

That year the National Institute of Statistics and Economic Studies in France estimated heat-related deaths of 11,000 throughout the summer.

At the last Olympics in Tokyo in 2021, extreme heat made it “torturous” for athletes and volunteers, according to local meteorologists.

It was the hottest Olympic Games on record with sweltering temperatures of 34C and humidity of 70%, which would have made it feel like 47C.

Tennis player Daniel Medvedev spoke of “dying on court” during the heat of a match.

Other competitors vomited and fainted on the finish line because of the high temperatures.

With Summer Heat Waves, The Media’s Having A Field Day Pushing Climate Change Lies

by Editorial Board, One 18, 2024  in ClimatChangeDispatch

city sun heat wave

There’s a summer heat wave going on, which gives journalists the opportunity to fill up their stories with climate change boilerplate. [emphasis, links added]

It no longer matters whether any of it is true. Just the opposite, in fact. If you point out the truth, you’re accused of being a denier.

Sure, the data doesn’t show an increase in the number or intensity of hurricanes or tornadoes or wildfires. Yet every time one or the other strikes, the press robotically connects that event to “climate change.”

Every tornado season, we hear about how climate change is making them more frequent and more deadly. Except the facts don’t support the narrative.

The world is using more oil, coal and gas than ever before and will use more. Net Zero is dead

by P. Homewood, June 14, NotaLotofPeopleKnowThat

A recent flurry of forecasts offers us a range of different views on what’s happening to the global demand for, and use of, crude oil. One thing seems to be clear, however: the chances of net zero carbon emissions in the near term – ie, by 2050 – are basically zero.

The year so far has been a bit of a rollercoaster ride in this realm of uncertainty, with projections and forecasts more volatile than the market itself. Crude prices have remained relatively strong despite various occurrences across Europe and the Middle East that would have resulted in major upsets in decades past.

One major point of consensus related to global oil demand growth is the expectation that it will continue to be robust, driven by a combination of factors including economic recovery, increased travel, and surging industrial activity in non-OECD nations.

The only major body not seeing continued, massive growth is the International Energy Agency (IEA), which revised its numbers this week to predict that crude demand will rise by just 1 million barrels per day (bpd) next year and will (at last!) peak “towards the end of this decade” at 106 million bpd, up from 102 million at the moment. The IEA expects this growth to be led by non-OECD countries, particularly China and India. The IEA and others have highlighted the importance of these regions in driving global oil demand.

The IEA, which is funded by 31 industrialized nations through a dues structure, says that it believes growth in demand from India, China and elsewhere will be gradually outweighed by the expected rollout of electric vehicles and other green technologies. However, one should note that the agency has been shifting for a long time from being an analytical organisation to being essentially a green campaigning one, and its forecasts nowadays are as much attempts to influence markets as to genuinely predict them.

In contrast to the IEA, the US Energy Information Administration (EIA) raised its 2024 global oil demand growth forecast to 1.1 million barrels per day, up from its previous estimate of 900,000 bpd. This revision is based on expectations for travel and tourism in the second half of the year. EIA projects even stronger demand growth for 2025 of 1.5 mbpd, again clashing with the IEA which sees just 1 mbpd that year, with non-OECD countries accounting for most of the growth. The US federal agency also raised its projection for crude prices to rise to an average of $87/barrel in Q4 2024 based on the rising demand.

The Earth Before Hydrocarbons

by B. Stewart, Apr 26, 2024 in ClimateChangeDispatch

prehistoric earth life plants

The Earth is approximately 4.5 billion years old. During the first four billion years, there were no hydrocarbons beneath the surface: no coal, no oil, no natural gas.

All the carbon atoms on Earth are in plants, animals, or the atmosphere. Yet the oceans did not boil. The Earth was not too hot for life. If it had been we would not be here.

The first lifeforms arose early in Earth’s existence.

The earliest fossils of microbes themselves, rather than just their byproducts, preserve the remains of what scientists think are sulfur-metabolizing bacteria. The fossils also come from Australia and date to about 3.4 billion years ago. (Wacey, D., Kilburn, M. R., Saunders, M., Cliff, J., and Brasier, M. D. (2011). Microfossils of sulfur-metabolizing cells in 3.4-billion-year-old rocks of Western Australia. Nature Geoscience, 4, 698-702. http://dx.doi.org/10.1038/ngeo1238.)

Bacteria are relatively complex, suggesting that life probably began a good deal earlier than 3.5 billion years ago.

However, the lack of earlier fossil evidence makes pinpointing the time of life’s origin difficult (if not impossible). (Hypotheses about the origins of life, Khan Academy.)

Organisms evolved that employ the process of photosynthesis. This plant life continues to consume carbon dioxide (CO2) and produce oxygen.

After a billion years or so, an atmosphere resembling that of the present day began to take shape. Earth’s present atmosphere is composed as follows:

It is important to note that in the above circle graphs, nitrogen, oxygen, and argon compose 99.964% of our atmosphere. The amount of CO2 is 0.04%.

Australia’s Defence 1: Name Your Enemy

There is only one threat we have to worry about and its name is China. China has been making plenty of threats for over 20 years now but these have been ignored because it would be inconvenient to take them seriously.

Actually, China’s threats started before WW2. They have been in abeyance until they had the resources to act on them. Figure 1 shows a map from a Nationalist primary school textbook in 1938, showing where they thought China’s borders should be:

Nutritive Value of Plants Growing in Enhanced CO2 Concentrations (eCO2)

by CO2 Coalition, Apr 22, 2024

We are pleased to announce the publication of our latest research report Nutritive Value of Plants Growing in Enhanced CO2 Concentrations (eCO2).

Despite many years of claims that increasing concentrations of CO2 are an “existential threat” to life on Earth, one cannot identify any harm that has been done. In fact, the only clear result of increasing CO2 has been an overall greening of the Earth and increasing productivity of agricultural and forest crops.

The evidence for greening of the Earth from eCO2 is now too obvious to deny. In recent years, some researchers have claimed that that nutritional values are negatively affected by elevated CO2 concentrations. Media promoters of climate alarmism have seized on these results to further demonize CO2.

In this paper we explain why the nutritional value of our more abundant crops can and will remain high as atmospheric CO2 concentrations increase toward values more representative of those existing throughout most of Earth’s history.

While this is a somewhat technical report, it is a valuable tool for you to put in your quiver to use the next time you see increased CO2 being linked to declining nutrition.

Climate Change Is Normal and Natural, and Can’t Be Controlled

by F.B. Soepyan, Apr 22, 2024 in WUWT

NASA claimed that “Earth is warming at an unprecedented rate” and “human activity is the principal cause.” Others proposed spending trillions of dollars to control the climate. But are we humans responsible for climate change? And what can we do about it?

“The climate of planet Earth has never stopped changing since the Earth’s genesis, sometimes relatively rapidly, sometimes very slowly, but always surely,” says Patrick Moore in Fake Invisible Catastrophes and Threats of Doom. “Hoping for a ‘perfect stable climate’ is as futile as hoping the weather will be the same and pleasant, every day of the year, forever.”

In other words, climate change is normal and natural, and you can forget about controlling it.

For instance, a major influence of weather and climate are solar cycles driven by the Sun’s magnetic field over periods of eight to 14 years. They release varying amounts of energy and produce dark sunspots on the Sun’s surface. The effects of solar cycles on Earth vary, with some regions warming more than 1°C and others cooling.

Climatic changes occur as a result of variations in the interaction of solar energy with Earth’s ozone layer, which influences ozone levels and stratospheric temperatures. These, in turn, affect the speed of west-to-east wind flows and the stability of the polar vortex. Whether the polar vortex remains stable and close to the Arctic or dips southward determines whether winters in the mid-latitudes of the Northern Hemisphere are severe or mild.

In addition to solar cycles, there are three Milankovitch cycles that range in length from 26,000 to 100,000 years. They include the eccentricity, or shape, of Earth’s elliptical orbit around the Sun. Small fluctuations in the orbit’s shape influence the length of seasons. For example, when the orbit is more like an oval than a circle, Northern Hemisphere summers are longer than winters and springs are longer than autumns.

BBC’s Coral Propaganda

by P. Homewood, Apr 16, 2024 in NotALotOfPeopleKnowThat

The BBC is corrupt, and this report is fraudulent:

It has triggered the fourth global mass coral bleaching event, according to the US National Oceanic and Atmospheric Administration (NOAA).

Bleaching happens when coral gets stressed and turns white because the water it lives in is too hot.

Coral sustains ocean life, fishing, and creates trillions of dollars of revenue annually.

https://www.bbc.com/news/science-environment-68814016

For a start, there has been no “devastating toll”, as the BBC pretends, from the possibility that the world is slightly warmer than a few years ago. (Given margins of error, there is no certainty about this.)

But more importantly, Rannard grossly misrepresents the science. Coral does not “turn white” because the water is too hot. Nor is this is a rare occurrence, as the “fourth global mass coral bleaching event” implies.

On the contrary, bleaching is a common event, which can take place for all sorts of reasons, including when the water gets too cold.

As the leading coral reef expert Dr Peter Ridd has explained, “bleaching” is merely part of a natural process, when coral expels algae in order to switch to a different type which is more suitable adapted to new conditions.

According to Ridd, coral cover on the Great Barrier Reef last year reached record levels, despite four supposedly catastrophic bleaching events in the six years prior to 2022. Neither has there been any significant change in corals worldwide.

Rannard’s article has nothing to do with science; it is just more scaremongering propaganda.

Three More New Temperature Reconstructions Document A Warmer Medieval Period

by K. Richard, Apr 11, 2024 in NoTricksZone

he North Atlantic, the Pacific Northwest (USA), and northern Finland were all warmer than today between 1000 and 2000 years ago.

Today’s (2000 CE) July air temperatures in the Azores – archipelago islands in the middle North Atlantic, ~1400 km west of Portugal – are visually shown to average about 10 to 11°C in a newly published reconstruction (Raposeiro et al., 2024).

This average air temperature is about 1 to 2°C warmer than this location’s Little Ice Age climate, or the coldest period (~9.1°C from 1750-1800) of the last 2000 years. However, the Medieval Climate Anomaly (MCA) had temperatures reaching into the 13-15°C range, which is 3-4°C warmer than modern.

…

 

A temperature reconstruction from a lake in the USA’s Pacific Northwest (Baig, 2024) indicates glacial temperatures were only 1.0 to 1.6°C colder than the modern temperature, 12.2°C. Temperatures reached 13.7°C, or 1.5°C warmer than today, ~2500 years ago, and then fluctuated between 12.6 and 12.2°C from 1900 years ago until today, a period encompassing both the Medieval Warm Period and Little Ice Age.

…

Another lake sediment temperature reconstruction using branched glycerol dialkyl glycerol tetraethers (brGDGTs) from northern Finland (Otiniano et al., 2024) suggests the modern temperature (represented as the blue diamond) is among the coldest of the last ~8000 years. Temperatures were much warmer than modern about 1200 to 1500 years ago, and throughout the period from 7000 to 3000 years ago.

The Anthropocene is not an official stratigraphic unit

by A. Préat and B. Van Vliet-Lanoë, Apr 12,2024 in SCE

Main theme: Ever since the idea of a new geological unit, the Anthropocene, waslaunched in 2000 by Paul Crutzen, an atmospheric chemist and Nobel Prize winner, the scientific community has been inflamed by the current global warming situation, and passionate debates have raged between those in favor of this new anthropogenic unit and those opposed to it. The discussion has spread well beyond the geological community, yet it is geologists, and geologists alone, who are able to formally define geological units, in this case stratigraphic units. Our article will reviewthe rules of stratigraphy and show that the introduction of the Anthropocene as a stratigraphic unit does not comply with these rules. After 15 years of debate, the ICS (International Commission on Stratigraphy) has just officially rejected the Anthropocene as a stratigraphic unit. In conclusion, the Anthropocene must be
considered as a ‘Geo-ethical’ unit and not as a ‘Geological’ unit.

3 New Studies Confirm Sea Levels Were 5 to 9 Meters Higher 7,000-5,000 Years Ago Than Today

by K. Richard,  Apr 1, 2024 in ClimateChangeDispatch

Modern relative sea levels are near the lowest in the last 7,000 years.

Two studies, independently published, identified Mid-Holocene sea levels in northern Norway (north of the Arctic Circle) as being 7 to 9 meters higher than today before declining to the present (Balascio et al., 2024, Nielsen et al., 2024). [emphasis, links added]

As the climate deteriorated into the Little Ice Age cooling centuries after the Medieval warmth, the accompanying sea level fall led to abandoned residences, ships, and harbors.

The seas had become too shallow to sail in.
