Recently : field works (3 to 5 weeks) Congo- Brazzaville 2012, 2015, 2016 (carbonate Neoproterozoic). Degree in geological sciences at the Free University of Brussels (ULB) in 1974, I went to Algeria for two years teaching mining geology at the University of Constantine. Back in Belgium I worked for two years as an expert for the EEC (European Commission), first on the prospecting of Pb and Zn in carbonate environments, then the uranium exploration in Belgium. Then Assistant at ULB, Department of Geology I got the degree of Doctor of Sciences (Geology) in 1985. My thesis, devoted to the study of the Devonian carbonate sedimentology of northern France and southern Belgium, comprised a significant portion of field work whose interpretation and synthesis conducted to the establishment of model of carbonate platforms and ramps with reefal constructions. I then worked for Petrofina SA and shared a little more than two years in Angola as Director of the Research Laboratory of this oil company. The lab included 22 people (micropaleontology, sedimentology, petrophysics). My main activity was to interpret facies reservoirs from drillings in the Cretaceous, sometimes in the Tertiary. I carried out many studies for oil companies operating in this country. I returned to the ULB in 1988 as First Assistant and was appointed Professor in 1990. I carried out various missions for mining companies in Belgium and oil companies abroad and continued research, particularly through projects of the Scientific Research National Funds (FNRS). My research still concerns sedimentology, geochemistry and diagenesis of carbonate rocks which leads me to travel many countries in Europe or outside Europe, North Africa, Papua New Guinea and the USA, to conduct field missions. Since the late 90's, I expanded my field of research in addressing the problem of mass extinctions of organisms from the Upper Devonian series across Euramerica (from North America to Poland) and I also specialized in microbiological and geochemical analyses of ancient carbonate series developing a sustained collaboration with biologists of my university. We are at the origin of a paleoecological model based on the presence of iron-bacterial microfossils, which led me to travel many countries in Europe and North Africa. This model accounts for the red pigmentation of many marble and ornamental stones used in the world. This research also has implications on the emergence of Life from the earliest stages of formation of Earth, as well as in the field of exobiology or extraterrestrial life ... More recently I invested in the study from the Precambrian series of Gabon and Congo. These works with colleagues from BRGM (Orléans) are as much about the academic side (consequences of the appearance of oxygen in the Paleoproterozoic and study of Neoproterozoic glaciations) that the potential applications in reservoir rocks and source rocks of oil (in collaboration with oil companies). Finally I recently established a close collaboration with the Royal Institute of Natural Sciences of Belgium to study the susceptibility magnetic signal from various European Paleozoic series. All these works allowed me to gain a thorough understanding of carbonate rocks (petrology, micropaleontology, geobiology, geochemistry, sequence stratigraphy, diagenesis) as well in Precambrian (2.2 Ga and 0.6 Ga), Paleozoic (from Silurian to Carboniferous) and Mesozoic (Jurassic and Cretaceous) rocks. Recently (2010) I have established a collaboration with Iraqi Kurdistan as part of a government program to boost scientific research in this country. My research led me to publish about 180 papers in international and national journals and presented more than 170 conference papers. I am a holder of eight courses at the ULB (5 mandatory and 3 optional), excursions and field stages, I taught at the third cycle in several French universities and led or co-managed a score of 20 Doctoral (PhD) and Post-doctoral theses and has been the promotor of more than 50 Masters theses.

The Green Deal in the light of geology

by A. Préat, Jan 31, 2025 in ScienceClimatEnergie

The Green Deal, an extension of the Paris Agreement (COP21, 2015), concerns three simultaneous transitions: ecological, energy and digital. Its aim is to develop a totally carbon-free economy in Europe by 2050, i.e. to achieve the Net Zero objective set by the European Commission.  How will this be achieved? By developing an electricity grid, a car fleet made up of 100% electric vehicles equipped with batteries (NMC) and an energy mix that is more than 80% (from 2030) supplied by wind turbines and photovoltaic panels. Intermittent renewable energies will be used for the most part. This also means replacing the fossil fuels used for transport and heat (‘flames’) with electricity from renewable sources.

To achieve this goal, which will require gigantic quantities of critical metals, the European Commission has no other solution than to revive mining activity by re-exploiting old mines, opening new ones and extending or deepening existing mines. The required quantities of critical metals are enormous and Europe, our continent, doesn’t have them. For lack of a favorable geological context, Europe is a ‘mining dwarf’ on a global scale. We account for 6% of the world’s population, we consume 25 to 30% of the worldwide production and produce only 5% to meet our needs. Since the 1990s, we have been at the bottom of the list in terms of exploration efforts, with just 3%. We are far behind the Anglo-Saxon and Asian companies, which dominate not only exploration but also the production of minerals. Our reserves are small in relation to what is at stake. Only 2% of the metals we need for the energy transition are available on the European continent (CDS, 2023).

So, how can we achieve the energy transition if we don’t have the materials to do it? The Commission has laid down 4 rules to remedy our shortcomings: (i) to product 10% of our annual consumption (in other words, we will always be 90% dependent on the outside world!); (ii) to process at least 40% of our annual consumption on site; (iii) to recycle at least 15% of metals for our annual consumption; and (iv) not to depend on any one country for more than 65% of our annual consumption in order to avoid excessive criticality. To date, none of these recommendations has been met. Europe also favors the development of a circular economy at a rate of 75%, which currently stands at just under 12% and has fallen in recent years.

EU is faced with a challenge. Has it considered the short-term agenda it has set itself for Net Zero? This agenda must include the long-term dimension of mining: exploration and prospecting are long phases. It takes an average of 17 years and very large budgets to open a new mine, in the hope that it will fully meet expectations. What’s more, because of the tense global economic and geopolitical situation, exploration efforts in non-ferrous metals have recently fallen by a few percent… According to the UN (2024), there is a shortfall of 225 billion dollars in investment in projects to extract essential minerals. What’s more, unlike in the past, to open a mine you will have to face determined opposition from environmental NGOs and citizens, who will lodge numerous legal appeals, which will delay the opening for a long time.

Ultimately, this transition will replace dependence on fossil fuels with dependence on metals. This was the case with forests: wood had been the exclusive fuel for metallurgy for several centuries and was replaced by coal in the 19th century to preserve the forests. Coal was then replaced by oil and gas (less polluting) and today fossil fuels will be replaced by metals to achieve decarbonation, as requested by the European Commission.

Programs to identify our mining potential have already been launched in 2018. They tell us, for example, that we have limited potential in rare earths, which are ultra-dominated by China and are a central pillar of so-called ‘high-tech’ technologies. We have no rare earth mines. However, a deposit of rare earths was discovered in January 2023 in Lapland (Sweden). It is thought to contain 1% of the world’s reserves, and production is planned within 10 to 15 years. Yes, mine time is a long time…

Doesn’t this decarbonation seem like a forced march? Many think so… others go further and question it…

Climate Whiplash and California Wildfires

by R. Caiazza, Feb 2, 2025 in WUWT

The difference between weather and climate is constantly mistaken by climate change advocates Recently Southern California wildfires have been blamed on climate change.  Patrick Brown addressed the question how much did “Climate Whiplash” impact the Los Angeles fires.  His excellent analysis raises concerns that I want to highlight.

Weather vs. Climate

Every time there is an extreme weather event proponents for eliminating fossil fuels confuse weather and climatewhen they claim the effects of GHG emissions on global warming are obvious today. According to the National Oceanic and Atmospheric Administration’s National Ocean Service “Weather reflects short-term conditions of the atmosphere while climate is the average daily weather for an extended period of time at a certain location.”  It goes on to explain “Climate is what you expect, weather is what you get.”

Hydroclimate Volatility

Patrick Brown described the Swain et al. (2025): Hydroclimate Volatility on a Warming Earth Nature review paper. He quoted the first line of the UCLA Press Release for the paper: “Los Angeles is burning, and accelerating hydroclimate whiplash is the key climate connection”  and remarked: “Thanks in no small part to the huge journalistic audience that lead author Dr. Daniel Swain commands, the “climate whiplash” vernacular was immediately adopted in international headlines covering the recent Los Angeles fires.”  This is a classic example of an extreme weather event that is linked to climate change by organizations and individuals that have a vested interest in advancing the threat of climate change.

Climate Whiplash

I have never heard of the concept of climate whiplash before this story broke.  Brown explains:

Dangerous, intense wildfires require dry vegetation. The idea behind the climate whiplash connection to the Los Angeles fires is that very wet winters in Southern California in 2022-2023 and 2023-2024 enabled a great deal of vegetation growth but that the very dry beginning of the 2024-2025 winter allowed that vegetation to dry out, resulting in a landscape primed for uncontrollable wildfires. Swain explains the mechanism in interviews with Adam Conover and Neil deGrasse Tyson.

In order for this to be a climate change problem, we need to know whether these events are increasing.  Brown noted that:

The idea being conveyed is that these climate whiplash events are dramatically increasing not just in Southern California, but globally.  “Every fraction of a degree of warming speeds the growing destructive power of the transitions” Swain said.

Brown described background for this concept:

…

…

Conclusion

Patrick Brown does an excellent job eviscerating the climate whiplash headlined stories based on Swain et al. (2025)’s recent paper.  It is frustrating that biased analyses that confirm pre-conceived get so much attention.  It will require many evaluations like Brown’s to address the misinformation.

How the Green Energy Narrative confuses things

by R. Schussler, Feb 2, 2025 in WUWT

Prequel to “Unravelling the narrative supporting a green energy transition.”

There is a powerful but misleading narrative supporting a green energy transition. A follow up piece will look more broadly at the general narrative supporting a transition to net zero.  This prequel will provide some detail on a few  components of the energy narrative and how this misleading narrative was established. The green energy narrative works somewhat like a magician’s patter, overemphasizing many things of irrelevance and distracting the audience from the important things going on. Misdirection ensures small truths are misinterpreted and magnified, leading to completely unrealistic hopes and expectations.

…

…

Conclusion

It is becoming increasingly apparent that wind, solar and batteries when pursued at high penetration levels result in high costs, lower reliability and poorer operational outcomes. Expectations from the green energy narrative and real-world results are not consistent and this gulf will continue to widen as long as policy makers continue to reflexively buy into the green energy narrative. This  piece has attempted to illuminate some of the mechanisms that served to produce and sustain the exceedingly  and overly high expectations for a green transition.  The narrative was built upon these and other various deceptions to provide disinformation and hide the  real-world challenges. Such methods continue to be employed with increasing frequency. The follow to this piece up will more systemically examine the components of the green energy narrative and raise many items of critical importance considerations that the green energy narrative ignores.

Scientists don’t know why 2024 was so hot

by D. Whitehouse, Jan 29, 2025 in NetZeroWatch

2024 broke many records.

There’s no doubt that 2024 was the hottest year of the instrumental period. But why it was so warm is not exactly clear, even with the backdrop of increasing global temperatures.

Over the years we have heard a lot about consensus when it comes to climate science. Sometimes it has been manufactured, for example the suggestion that 97% of all scientists believe global warming is real, but in many cases it does represent what is at least a snapshot of what scientists think is happening.

So it was on December 10th at the American Geophysical Union meeting in Washington. A show of hands was requested in answer to the question as to whether we understand why 2023 and 2024 was so hot. Very few hands were raised. Asked a slightly different question, the majority of the audience raised their hands to the proposition that we can’t explain it.

The spike in, already elevated, global temperatures of 2023 and 2024 is beyond what can be explained by more CO2 in the atmosphere. It can’t be explained with El Niño, volcanic emissions or the decline in ship fuel pollution letting more sunlight reach the ocean. Something else is going on.

One team of researchers have suggested it’s due to a decrease in low cloud, which tends to cool our planet. If this is so, then it is important to see if it is a blip or a trend.

Reporting certainty

Such scientific niceties haven’t bothered most reporters dealing with the record-breaking warmth of 2024, which broke the 1.5°C Paris Agreement boundary.

Given that the increase is unexplained, is it wise to present it as evidence of a dangerous new phase in our broken clime, as New Scientist did? Despite the uncertainties, they say that Earth’s climate systems are no longer behaving as they should. It points to the wavering Jet Stream and the recent Californian wildfires as proof, even though it’s technically possible to explain these effects without climate change, catastrophic or not.

New Scientist says the one thing we can now expect ‘with certainty’ is that we ‘should’ expect extreme weather events to become more frequent. What is it? Is it certain, or just something that should happen?

The uncertainty extends into 2025. It was expected that El Niño, which boosted 2023 and 2024 temperatures, would have declined by mid-year, but it didn’t. It has hung on and is expected to linger for most of this year, to be followed by a weak and brief cooling La Niña.

I wonder if there will be another show of hands by puzzled scientists at the end of 2025.

Australian Heatwave Stories Cop Severe Criticism

by G. Sherrigton, Jan 29, 2025 in WUWT

The daily temperature observations from many Australian weather stations have now been routinely updated by the Bureau of Meteorology, BOM, to the end of year 2024.

Year 2024 has been publicized GLOBALLY as the “hottest year evah!” so it is time to examine how Australia fared. Here, heatwaves are the medium used.

The frequent, accepted chant is that globally, heatwaves are becoming “hotter, longer and more frequent”. This chant is not supported by the following heatwave analysis which examines 10 Australian weather stations with lengthy historic observations. This study has generated 160 graphs that are linked by weather station/city that is the main part of this article for readers to examine.

Here is a snapshot of Adelaide, using only 3-day heatwave examples, 4 graphs out of a possible 16 for Adelaide.

…

…

Some essential points:

  1. A day of missing data can lead to large damage to the calculations, because that 1 day affects 9 other days in the 10-DAY analysis. Therefore, all missing values were infilled, either by a subjective guess in the ballpark of surrounding values, or with the overall average Tmax value for the station. The shortest duration station, Brisbane, has some 50,400 days analyzed, with a few hundred missing values, so the odds of induced error are small. They can be traced.
  2. I have made the Excel commands as simple as possible. No knowledge of macros, programming or even Pivot tables is needed. The invitation is open for you to replicate the methodology for your own locations.
  3. I have not cherry picked the weather stations. Together, these 10 cities/locations house more than 70% of Australian population. This has meaning when planning for heatwaves, such as where to build hospitals and how large to make them.
  4. The chosen cities probably suffer from the temperature distortion of Urban Heat Island effect. There have been transect studies showing UHI in excess of a couple of degrees at times in both Sydney and Melbourne. I have now included two stations unlikely to have been affected by UHI, Cape Leeuwin and Longreach.

The Climate Sciences Use Of The Urban Heat Island Effect Is Pathetic And Misleading – Watts Up With That?

  1. Rebuttal of the misunderstanding that heatwaves are becoming “hotter, longer and more frequent” lacks credibility if actual data are used such s here, for 10 stations in far off Australia. It is hard to maintain that misunderstanding when simple graphs of real data are shown to those who make such claims. I am writing a more detailed analysis of these 160 graphs, should WUWT accept it.
  2. You are encouraged to make similar graphs for regions elsewhere. For heatwaves, they are hard to refute, in contrast with official/IPCC type studies, which usually commence after 1950 and which rely upon arcane definitions of heatwave to arrive at conclusions.

U.N. Confirms Notification Of America’s Exit From Paris Climate Deal

by S. Kent, Jan 29, 2025 in ClimateChangeDispatch

paris eiffel tower
Washington notified the United Nations on Tuesday to confirm it is delivering on a key campaign pledge of President Donald Trump and withdrawing from the Paris Climate Agreement to put U.S. energy and job growth first. [emphasis, links added]

On his first day back in the White House, Trump announced America would leave the accord, which is managed by the U.N. climate change body.

“In recent years, the United States has purported to join international agreements and initiatives that do not reflect our country’s values or our contributions to the pursuit of economic and environmental objectives,” Trump’s executive order reads.

“Moreover, these agreements steer American taxpayer dollars to countries that do not require, or merit, financial assistance in the interests of the American people.”

Now that moment has moved a step closer, AFP reports.

“I can confirm to you that the United States has notified the secretary-general, in his capacity as a depository, of its withdrawal on January 27 of this year from the Paris agreement,” said Stephane Dujarric, spokesman for U.N. chief Antonio Guterres.

“According to Article 28, paragraph two, of the Paris Agreement, the withdrawal of the United States will take effect on January 27, 2026.”

Trump previously withdrew the United States from the Paris Accord during his first term, as Breitbart News reported.

Inconvenient Climate Study Censored

by P. Homewood, Jan 14, 2025 in NotaLotofPeopleKnowThat

Another important paper taking issue with the ‘settled’ climate narrative has been cancelled following a report in the Daily Sceptic and subsequent reposts that went viral across social media. The paper discussed the atmospheric ‘saturation’ of greenhouse gases such as carbon dioxide and argued that higher levels will not cause temperatures to rise. The work was led by the widely-published Polish scientist Dr. Jan Kubicki and appeared on Elsevier’s ScienceDirect website in December 2023. The paper has been widely discussed on social media since April 2024 when the Daily Sceptic reported on the findings. Interest is growing in the saturation hypothesis not least because it provides a coherent explanation for why life and the biosphere grew and often thrived for 600 million years despite much higher atmospheric levels of greenhouse gases. Alas for control freaks, it also destroys the science backing for the Net Zero fantasy.

3 More New Drought And Temperature Reconstructions Do Not Support The Climate Alarm Narrative

by K. Richard, Jan 13, 2025 in NoTricksZone

Studies from Central China, Russia, and Central Europe indicate there was just as much (0r more) warming and drought prior to 1900, or when CO2 concentrations were under 300 ppm.

A new 1606 to 2016 Central China winter (minimum) temperature reconstruction (Jiang et al., 2024) reveals cold periods only occurred in 9 years of the 1600s (1663-1672), but there were 71 years of cold periods during the 20th century (1900-1942, 1959-1979, 1985-1994).

Notably, CO2 hovered around 278 ppm during the 1600s and 1700s, but it rose from 290 ppm to 370 ppm during the 1900s.

From 1650-1750 the winter temperatures in Central China were 0.44°C warmer than they were during the 20th century. The authors were surprised by this temperature result, as 1650-1750 falls within the timing of the Little Ice Age.

“Surprisingly, during 1650–1750, the lowest winter temperature within the research area was about 0.44 °C higher than that in the 20th century, which differs significantly from the concept of the ‘cooler’ Little Ice Age during this period. This result is validated by the temperature results reconstructed from other tree-ring data from nearby areas, confirming the credibility of the reconstruction.”

Finally, it should be noted that the year 1719 was 1.4°C warmer (-3.17°C) than the 1961-2016 average (-4.57°C).

…

A new 1803-2020 Central Europe precipitation reconstruction (Nagavciuc et al., 2025) determines droughts were more prolonged and pronounced during the 1800s than in the 1900s, as the 1900s were relatively wet. Only one recent period (2007-2020) endured extreme drought, but it did not exceed the severity of the 1818–1835, 1845–1854, 1882–1890 drought years.

Ancient Romans likely breathed lead pollution

by T.M. Brown, Jan 6, 2025 in Science

From 27 B.C.E. to 180 C.E., Rome enjoyed a period of relative peace and prosperity, the Pax Romana. It witnessed the beginning of the Roman Empire, the building of the Colosseum, and the expansion of the empire to encompass the entire Mediterranean and much of the British Isles. However, the industrial-scale silver smelting that accompanied such prosperity came with a dark side: lead pollution.

In a study published today in the Proceedings of the National Academy of Sciences, scientists for the first time quantified atmospheric levels of this pollutant and found the toxic metal likely led to diminished IQs for many ancient Romans.

“This is certainly a very interesting paper,” says Christopher Loveluck, an archaeologist at the University of Nottingham who was not involved in the study. “Lead emissions in the vicinity of mines and smelting sites by themselves could certainly have had an impact on the cognition and health of surrounding populations, and potentially wider rural populations.”

Today, scientists know that even minor, short-term exposure to lead-contaminated pipes, paints, and toys can lead to heart and cognitive problems, especially in infants and young children. And lead was ubiquitous in ancient Rome, including in ceramics, cosmetics, painted glaze, water pipes, and as a sweetener in wine. Researchers have even argued lead poisoning hastened the downfall of the Roman Empire.

Some Romans recognized its dangers. Pliny the Elder called the white lead powder used in Roman cosmetics a “deadly poison,” says Caleb Finch, a scientist at the University of Southern California who was not involved in the study. But although tooth enamel and skeletal remains testify to lead poisoning among some Romans, scholars have debated how serious a problem it was.

Airborne pollution accounted for much of the exposure, says Joseph McConnell, a research scientist at the Desert Research Institute and lead author of the study. The mining and smelting of silver from a lead-rich mineral called galena releases the toxic metal as a vapor, he says. “For every gram of silver produced, something like 10,000 grams of lead were produced.”

Met Office Try To Shut Down Debate On Junk Temperature Measurements

by P. Homewood, Jan 7, 2025 in NotaLotofPeopleKnowThat

hris Morrison has the latest on how the Met Office, in league with the green blob, are trying to shut down debate on the junk weather station scandal:

image

After a year of damaging revelations about the state of the Met Office’s temperature measuring network, the Green Blob-funded ‘fact-checker’ Science Feedback has sprung to the defence of the state-funded U.K. weather service. It has published a long ‘fact check’ seeking to exonerate practices that have recently come to light including the locating of stations with huge heat corrupted ‘uncertainties’ and the publication of invented data from 103 non-existent sites. Inept is a word that springs to mind. At one point, Science Feedback justifies the estimation of data at the non-existent stations by referring to the hastily changed Met Office explanation for station/location long-term averages. The original and now deleted Met Office webpage referenced station names and provided single location coordinates including one improbable siting next to the sea on Dover beach. This would appear to be a new low in the world of so-called fact-checking – designating copy as ‘misleading’ based on an explanation changed after the article was published.

England & Wales Rainfall Trends

It does not need me to tell you that it was quite wet last year. It was in fact ninth wettest in England & Wales since 1766, though nowhere near the two wettest years in 1872 and 1768.

For the last decade or so, we have been going through the same sort of weather as in the 1870s and 80s, as well as the 1920s.

But averages and trends are not particularly meaningful – nature does not do averages and straight lines! You could have ten years all with the same rainfall, or you could have five years with high rainfall and five years of drought, and you could get the same average.

If you just look at the distribution of wet years, there is no obvious pattern:

Climate Bombshell: New Evidence Reveals 30 Year Global Drop in Hurricane Frequency and Power

by C. Morrison, Jan 4, 2025 in DailySceptic

Last month a small but powerful cyclone named Chido made landfall in Mayotte before sweeping into Mozambique, causing considerable damage and leading to the loss of around 100 lives. Days after the tragedy, the Green Blob-funded Carbon Brief noted that scientists have “long suggested” that climate change is making cyclones worse in the region, while Blob-funded World Weather Attribution (WWA) at Imperial College London made a near-instant and curiously precise estimate that a Chido-like cyclone was about 40% more likely to happen in 2024 than during the pre-industrial age. Not to be outdone, Green Blob-funded cheerleader the Guardian chipped in with the obligatory “cyclones are getting worse because of the climate emergency”. Almost unnoticed, it seems, among all the Net Zero dooming and grooming was a science paper published during December by Nature that found no increase in the destructive power of cyclones – the generic term for typhoons and hurricanes – in any ocean basin over the last 30 years. In the South Indian basin, the location of cyclone Chido, there was a dramatic decrease in both frequency and duration in recent times.

Reality rarely gets much of a look-in these days when fanatical Net Zero activism is afoot, but the paper, written by a group of Chinese meteorologists, makes its case by considering the facts and the data. The scientists apply a “power dissipation index” (PDI) which they consider superior to single measure indicators since it combines storm intensity, duration and frequency. The graphs below show the cumulative index for tropical cyclones across all ocean basins along with a global indication.

Mystery Volcano’ that Lowered Global Temperatures Nearly 2 degrees Fahrenheit in 1831 Identified

by L. Eastman, Jan 5, 2025 in WUWT

Whenever I write about climate change, I often note that volcanoes can have significant impacts on the global climate.

A new example has been recently revealed, as a ‘mystery volcano’ that erupted in 1831 and significantly cooled Earth’s climate has finally been identified as Zavaritskii on Simushir Island, part of the Kuril Islands archipelago between Russia and Japan.

This eruption was one of the most powerful of the 19th century, releasing an enormous amount of sulfur dioxide into the stratosphere. The Earth-caused emissions resulted in a decrease of approximately one degree Celsius (1.8 degrees Fahrenheit) in the annual average temperatures of the Northern Hemisphere.

The challenge in locating the volcano was due to its remote location.

While the year of this historic eruption was known, the volcano’s location was not. Researchers recently solved that puzzle by sampling ice cores in Greenland, peering back in time through the cores’ layers to examine sulfur isotopes, grains of ash and tiny volcanic glass shards deposited between 1831 and 1834.

Using geochemistry, radioactive dating and computer modeling to map particles’ trajectories, the scientists linked the 1831 eruption to an island volcano in the northwest Pacific Ocean, they reported Monday in the journal Proceedings of the National Academy of Sciences.

..Before the scientists’ findings, Zavaritskii’s last known eruption was in 800 BC.

“For many of Earth’s volcanoes, particularly those in remote areas, we have a very poor understanding of their eruptive history,” said lead study author Dr. William Hutchison, a principal research fellow in the School of Earth and Environmental Sciences at the University of St. Andrews in the United Kingdom.

“Zavaritskii is located on an extremely remote island between Japan and Russia. No one lives there and historical records are limited to a handful of diaries from ships that passed these islands every few years,” Hutchison told CNN in an email.

To find the volcano, researchers compared the chemistry of microscopic shards of ash extracted from ice cores drilled in Greenland with samples from the Zavaritskii caldera. They determined it was a perfect match.

UK Temperatures In 2024

UK annual temperatures have dropped for the second year running, though the Met Office will emphasise what they claim is a remorseless upwards trend. However they don’t show error margins in their graphs, and as we know, nine out of ten of the weather stations used for their UK temperature dataset are junk or near junk sites, where poor siting can mean temperatures may be overstated by as much as five degrees for Class 5 and two degrees for Class 4:

Central Greenland Was Recently Ice-Free And Covered With Plants When CO2 Was Under 300 ppm

by K. Richard, Jan 3, 2025 in NoTricksZone

Today, with CO2 levels supposedly in the “dangerously high” range, Central Greenland has 3 kilometers of ice piled atop it.

Scientists have known since the GISP2 borehole was drilled in 1993 that Central Greenland deglaciated at least once in the late Pleistocene (Bierman et al., 2024). Indeed, the Summit of the modern Greenland ice sheet was actually ice-free at some point between 250,000 and 1.1 million years ago – which is relatively recent from a geological perspective.

Plants, wood, insects, fungi and other remnants suggestive of vegetation were recovered from the bottom of the boring site. This is quite a contrast to today’s 3000-meters-high ice sheet at this same location.

“The presence of poppy, spike-moss, fungal sclerotia, woody tissue, and insect parts in the GISP2 till shows that tundra vegetation once covered central Greenland, mandating that the island was largely ice-free.”

The atmospheric CO2 concentration is presumed to have ranged between 275 and 290 ppm during the Late Pleistocene, or during this same period when Greenland was ice-free. These sub-300 ppm CO2 levels are thought to be the same as they were from 1700 to 1900 (the Little Ice Age), when, as today, Central Greenland has remained buried in kilometers of ice.

The authors of this study use existing knowledge of Greenland’s climate (for example, Summit’s mean July temperature is -7°C) to calculate how much warmer Central Greenland was “when the ice was gone” during the last 1.1 million years. Controlling for lapse rate, Central Greenland’s average surface air temperatures were likely +3 to 7°C in July when it had no ice sheet.

The atmospheric CO2 concentration thus appears to be largely unrelated to either Greenland’s climate or its state of glaciation.

UAH v6.1 Global Temperature Update for December, 2024: +0.62 deg. C

by R. Spencer, Jan 3, 2025 in WUWT

2024 Sets New Record for Warmest Year In Satellite Era (Since 1979)

The Version 6.1 global average lower tropospheric temperature (LT) anomaly for December, 2024 was +0.62 deg. C departure from the 1991-2020 mean, down slightly from the November, 2024 anomaly of +0.64 deg.

…

The Version 6.1 global area-averaged temperature trend (January 1979 through December 2024) remains at +0.15 deg/ C/decade (+0.22 C/decade over land, +0.13 C/decade over oceans).

As seen in the following ranking of the years from warmest to coolest, 2024 was by far the warmest in the 46-year satellite record averaging 0.77 deg. C above the 30-year mean, while the 2nd warmest year (2023) was +0.43 deg. C above the 30-year mean. [Note: These yearly average anomalies weight the individual monthly anomalies by the number of days in each month.]

2025 Looks Bleak For Germany…Energy The Most Expensive In Europe …Growing Speech Tyranny

by P. Gosselin, Jan 1, 2025 in NoTricksZone

2025 in Germany will be a year more energy inflation and loss a free speech rights

Effective today, Germany’s CO2 surcharge will rise from 45 euros a tonne to 55 euros, which will further fan inflation and social discontent.

Already Germany’s electricity prices are among the highest in the world, and the most expensive in Europe:

Germany clamps down on dissenters, free speech

But 2025 will not be an easy year for dissenters and critics of the government, as this is increasingly being criminalized in Germany thanks to recently passed laws and acts that aim to suppress free speech.

The former head Germany’s Constitution Protection Authority (Bundesverfassungsschutz), Thomas Haldenwang (CDU Party), suggested last February when presenting measures to fight right-wing extremism, that human thoughts and speech patterns need to be under surveillance and become the business of the government: “It’s also about shifting verbal and mental boundaries. We have to be careful that thought and language patterns don’t become embedded in our language.”

10 Steps Trump Can Take To Restore America’s Energy Dominance

by D. Blackmon, Jan 2, 2025 in ClimateChangeDispatch

President-elect Donald Trump has a big job ahead of him in restoring common sense and sanity to federal energy policy when he takes office on January 20. [emphasis, links added]

The last four years in this realm can more accurately be characterized as a series of ill-considered, irrational scams than as any sort of coherent, productive set of policies.

It has been four years of bad policies — largely based on crass crony capitalism principles — that have done severe damage to America’s level of energy security.

No doubt cleaning up this mess left behind by President Joe Biden and his appointees will take the full four years of Trump’s second term. But the new president will be able to take some fast actions to jump-start the process as part of his first 100-day agenda.

With respect, here is a list of 10 quick common-sense actions Trump can take to begin to restore America’s energy security:

1 — Rescind Biden’s ridiculous permitting “pause” on LNG export infrastructure. Of all the Biden energy policy scams, this was perhaps the most heinous and unjustified of all. Terminate it immediately and get this American growth industry back on track.

2 — Terminate U.S. participation in the Paris Climate Agreement and any future annual COP conferences sponsored by the United Nations. Halt the spending of federal dollars related to any and all goals and commitments related to either of these wasteful processes.

3 — Terminate the office of Senior Advisor to the President for International Climate Policy, aka “the Climate Envoy,” currently occupied by John Podesta, and eliminate its budget.

Wind And Solar: The Hidden Truth Behind Those Rising Electric Bills

by Bjorn Borg, Jan 2, 2025 in ClimateChangeDispatch

Green Electricity Really Does Cost A Bundle

As nations use more and more supposedly cheap solar and wind power, a strange thing happens: Our power bills get more expensive. [emphasis, links added]

This exposes the environmentalist lie that renewables have already outmatched fossil fuels and that the “green transition” is irreversible even under a second Trump administration.

The claim that green energy is cheaper relies on bogus math that measures the cost of electricity only when the sun is shining and the wind is blowing.

Modern societies need around-the-clock power, requiring backup, often powered by fossil fuels. That means we’re paying for two power systems: renewables and backup.

Moreover, as fossil fuels are used less, those power sources need to earn their capital costs back in fewer hours, leading to even more expensive power.

This means the real energy costs of solar and wind are far higher than what green campaigners claim. One study shows that in China the real cost of solar power on average is twice as high as that of coal.

Similarly, a peer-reviewed study of Germany and Texas shows that solar and wind are many times more expensive than fossil fuels.

Germany, the U.K., Spain, and Denmark, all of which increasingly rely on solar and wind power, have some of the world’s most expensive electricity.

The International Energy Agency’s latest data (from 2022) on solar and wind power generation costs and consumption across nearly 70 countries shows a clear correlation between more solar and wind and higher average household and industry energy prices.

In a country with little or no solar and wind, the average electricity cost is about 12 cents a kilowatt-hour (in today’s money).

For every 10% increase in solar and wind share, the electricity cost increases by more than 5 cents a kilowatt-hour.

This isn’t an outlier; these results are substantially similar to 2019, before the effects of the pandemic and the war in Ukraine.

For every 10% increase in solar and wind share, the electricity cost increases by more than 5 cents a kilowatt-hour.

Scientists Uncover Cause of 1831 Global Cooling Event That Triggered Crop Failures, Famines

by J. Chadwick, Dec 31, 2024 in ClimateChangeDispatch

It’s been nearly 200 years since a global cold snap led to widespread crop failures and devastating famines. [emphasis, links added]

Now, a new study by scientists at the University of St Andrews finally pinpoints the cause.

The Zavaritskii volcano on the remote, uninhabited Russian island of Simushir, part of the Kuril Islands, erupted in 1831, the experts reveal.

The dramatic event injected volcanic ash into the atmosphere, blocking enough sunlight to induce a brief global cooling period.

The resulting change in weather included reduced rainfall from Africa and India to Japan, causing major famine due to poor crop yields.

‘While scientists have long known that a really big eruption went off in 1831, the source has remained a mystery,’ lead study author Dr Will Hutchison told MailOnline.

Trump Wants Greenland and the Panama Canal. It’s About Climate.

by L. Friedman, Dec 31, 2024 in TheNewYorkTimes

To imagine the kind of future a hotter, dryer climate may bring, and the geopolitical challenges it will create, look no farther than two parts of the world that Donald Trump wants America to control: Greenland and the Panama Canal.

The president-elect in recent days has insisted that both places are critical to United States national security. He’s called to reclaim control the Panama Canal from Panama and acquire Greenland from Denmark, both sovereign territories with their own governments.

They have something else in common as well: Both are significantly affected by climate change in ways that present looming challenges to global shipping and trade.

Because of warming temperatures, an estimated 11,000 square miles of Greenland’s ice sheets and glaciers have melted over the past three decades, an area roughly equivalent to the size of Massachusetts. That has huge implications for the entire world. If the ice melts completely, Greenland could cause sea levels to rise as much as 23 feet, according to NASA.

Scientists Report A ‘Striking Global Greening Trend’ Over The Last 42 Years

by K. Richard, Dec 30, 2024 in NoTricksZone

The greening of the Earth’s vegetated areas is “attributed to CO2 fertilization, climate change, and land use changes.”

New remote sensing research (Gutiérrez-Hernández and García, 2025) uses robust statistical methods to eliminate false positives and spurious correlations in establishing vegetation trends in the satellite era.

The scientists find 38% of the Earth’s land surface has undergone statistically significant greening or browning trends over the last 42 years (1982-2023). Conventional methods (i.e., Mann-Kendall test) that had previously found 51% of the Earth’s surface experienced statistically significant vegetation trends in the satellite era may overlook crucial factors that produce less accurate, inflated results.

With this new analytical method, the True Significant Trends (TCT) test, the authors have robustly determined there has been a “striking global greening trend” attributed to CO2 fertilization and climate change.

“Applying a new proposed workflow methodology (True Significant Trends, TST) we reveal a striking global greening trend, with a significant portion of the Earth’s terrestrial land surface showing increases in vegetation cover over the past four decades, particularly in Eurasia.”

Specifically, 76.1% to 85.4% of statistically significant vegetation trends indicate greening, whereas browning trends account for 14.7 to 23.9%

“Among these significant trends identified using the TST workflow, 76.07% indicated greening, while 23.93% indicated browning. Notably, considering areas (pixels) with NDVI values above 0.15, greening accounted for 85.43% of the significant trends, with browning making up the remaining 14.57%. These findings strongly validate the ongoing global greening of vegetation.”

Recent Temperature Falls Likely to Put a Dampener on ‘Hottest Year Evah’ Stories

by C. Morrison, Dec 28, 2024 in TheDailySceptic

Stand by for another bout of ‘Hottest Year Evah’ stories as the mainstream media pursues its campaign to induce mass climate psychosis and prepare the ground for the oncoming Net Zero catastrophe. Alas, enjoy it only a little while longer since this story may have to be retired after putting in such a sterling propaganda shift. Global temperatures are falling like a stone, while the oceans are cooling at a remarkably rapid rate. In the U.K., the year is likely to show a second annual temperature fall since the alleged ‘record’ year in 2022.

Only last May, Matt McGrath and Justin Rowlatt at the BBC were claiming that “fuelled by climate change” the world’s oceans had broken temperature records every single day over the past year. Planet-warming gases were said to be “mostly to blame”. Three days were singled out when the previous highs were beaten by 0.34°C. Inexplicably, the story, a matter it might be thought of some ongoing concern, was not followed up. The graph below, compiled from data supplied by the U.S. weather service NOAA, might help explain why.

Habitat Destruction Offsets for “Renewables” are just Indulgences

by D. Wojick, Dec 28, 2024 in WUWT

A bad idea is emerging in the “renewables” world, namely that projects can buy their way out of destroying natural habitats. The wind and solar projects still destroy the natural habitats they are built on but they fund a magic wand that somehow supposedly creates new compensating habitat someplace else. Not really.

The fallacy here is that every acre in America already has a habitat. You can change an acre’s habitat from one form to another but not create one. It is a zero sum game.

There is a long standing, highly specialized development offset program that helps make the point. This is wetlands protection under section 404 of the Clean Water Act. Wetlands are deemed to be so special that filling one in for development can be offset by creating one someplace else.

But if you convert dry land to wetland you have destroyed the dry land habitat. So the amount of habitat destruction is not reduced, just the amount of wetland destruction.

The supposed renewables habitat destruction offset does nothing like the 404 program. The renewables developer simply pays to have habitat created someplace else which is impossible. For reference these programs are often called Biodiversity Offsetting which sounds nice.

Such a program might create habitat somewhere that matches that destroyed by the renewables project but that requires destroying the present habitat of the offset site. For example creating a woodland by destroying a grassland. Or vice versa, bulldozing a forest to create a grassland. This might even mean destroying farmland.

Clearly this is nonsense. It is a form of indulgences, which means paying for sin, in this case the sin of habitat destruction. Because solar and wind certainly destroy the habitat they are developed on.

Climate Alarmists Push AMOC Collapse AND Greenland Ice Collapse

Climate change is the worst. Here’s just how bad it got this year.

By Hannah Osborne

The big news in Earth science this year was all about climate change, with extreme weather, flooding and drought attributed to warming. Scientists also warned about much worse to come if we don’t rein in carbon emissions.

…

Climate change devastation edging closer

But some of the scariest news about the planet isn’t what happened this year but rather what could occur if we don’t stop spewing carbon into the atmosphere. A study published in June suggested ecological tipping points — such as the collapse of the Greenland Ice Sheet and the transformation of the Amazon rainforest into savanna — could be reached in just 15 years if climate change isn’t controlled.

In October, scientists penned an open letter warning about the risk posed by the collapse of a key Atlantic current. In it, researchers urged policymakers to address the threat posed by the weakening Atlantic Meridional Overturning Circulation (AMOC) — a giant ocean conveyor belt that transports heat to the Northern Hemisphere, and the breakdown of which could cause temperatures across Europe to plummet.
