The “Collapsing Gulf Stream” Scare is Back—Again

by C. Rotter, Feb 5, 2025 in WUWT


Ah, the Atlantic Meridional Overturning Circulation (AMOC) collapse—our old friend. Like a horror movie franchise that refuses to die, the idea that the Gulf Stream is about to shut down and plunge Europe into an icy apocalypse has returned. This time, the BBC is breathlessly warning that “the chance of it happening is growing”​. But before you start knitting survivalist-grade wool socks, let’s take a moment to review how many times we’ve heard this story before—and why it never seems to pan out.

A Climate Catastrophe… Someday, Maybe, Possibly

According to the BBC, AMOC is supposedly “getting weaker,” but they immediately admit that direct measurements have only been taken since 2004—meaning we have barely two decades of actual data​. Now, call me old-fashioned, but when you’re talking about an ocean system that has been operating for millions of years, 20 years of data is like trying to predict a person’s entire life based on a single Tuesday morning.

And what’s their big evidence? Ocean floor sediments and a “cold blob” in the Atlantic. That’s right, they’re looking at dirt samples and a patch of water that isn’t warming like the rest of the ocean, and somehow, this is supposed to spell doom for civilization​.

This wouldn’t be so bad if they admitted the uncertainty. Instead, the article plays a game of “it’s probably not happening, but it totally could!” For instance, the IPCC says they have “medium confidence” that AMOC will notcollapse this century. But some other scientists say, well, maybe it could! As one of them warns, we “maybe need to be worried”​.

What kind of science is this? It sounds more like a horoscope than a serious climate analysis.

Fear-Mongering 101: Every Climate Scare is the Last One

Australian Heatwave Stories Slammed Some More. Part 2.

by G. Sherrington, Feb 6, 2025 in WUWT


There were 10 significant weather station/city sites explored for their heatwave properties in the first article of this series, 5 days ago.

Australian Heatwave Stories Cop Severe Criticism – Watts Up With That?

That first article shows 160 graphs of hottest heatwave temperatures over the years when records have been kept, for Adelaide, Alice Springs,  Brisbane, Cape Leeuwin, Darwin, Hobart, Longreach, Melbourne, Sydney and Perth. This second article deals with some patterns of interest.

I wrote the articles because many Establishment sources make claims like this one from the Climate Council of Australia, 2014:

“Climate change is already increasing the intensity and frequency of heatwaves in Australia. Heatwaves are becoming hotter, lasting longer and occurring more often.”

HEATWAVES: HOTTER, LONGER, MORE OFTEN

An Internet search using “heatwaves longer hotter more often” returns these 6 hits and more.

Heatwaves to be hotter, longer and more frequent, climate change report says – ABC News

HOTTER?

Using practically all years of data recorded, I examined each of 4 heatwave durations of 1, 3, 5 and 10 days. The raw data are from the Climate Data Online CDO source by the Bureau of Meteorology.

The first half of the heatwave numbers is compared to the last half. The first half numbers are subtracted from the second half numbers. If there is warming, the difference is positive. If there is cooling, the difference is negative.

This example summarises the method by a graph.

Equinor Cut Green Investment In Half

by P. Homewood, Feb 6, 2025 in NotaLotofPeopleKnowThat


Norwegian energy giant Equinor is halving investment in renewable energy over the next two years while increasing oil and gas production.

Chief executive Anders Opedal said that the transition to lower carbon energy was moving slower than expected, costs had increased, and customers were reluctant to commit to long term contracts.

Mr Opedal told the BBC he was confident that Rosebank – a giant new oil field in the North Sea – would go ahead, despite a recent court ruling that consent had been awarded unlawfully.

He also warned that gas prices could rise next winter as European gas storage levels were lower now than this time last year.

“We are scaling down our investments in renewables and low carbon solutions because we don’t see the necessary profitability in the future,” Mr Opedal said.

It will cut investments in renewables to $5bn over the next two years, down from about $10bn.

It will also drop a target to spend half of its fixed assets budget on renewables and low carbon products by 2030.

By contrast, Equinor will be increasing oil and gas production by 10% over the next two years.

https://www.bbc.co.uk/news/articles/c1jg7k1kjwyo

This is of course part of a much wider trend, as we saw today with Orsted’s decision to call a halt to offshore wind development. Renewable energy is wholly dependent on govt subsidy, which as President has shown is illusionary.

Incredibly the far-left BBC still believe that “Rosebank is not straightforward”

What could not be more straightforward than a British oil field which could supply ultra cheap oil and gas to the country, sustain thousands of well paid jobs, send millions in tax revenues to the govt, provide an element of energy security and actually reduce emissions in comparison with importing the stuff.

Only the British hating BBC could object to that!

BTW

I cannot help but be reminded what the Xi’s useful idiot, Ambrose Evans-Pritchard said last week, when he said that the world’s investors were chasing green energy because that was where the money was!

Dream on, Ambrose!!!!!!!!!!!!!

Hottest January? Latest BBC Lies!

by P. Homewood, Feb 6, 2025 in NotaLotofPeopleKnowThat


Last month was the world’s warmest January on record raising further questions about the pace of climate change, scientists say.

January 2025 had been expected to be slightly cooler than January 2024 because of a shift away from a natural weather pattern in the Pacific known as El Niño.

But instead, last month broke the January 2024 record by nearly 0.1C, according to the European Copernicus climate service.

https://www.bbc.co.uk/news/articles/cwyjk92w9k1o

The reality is somewhat different, as satellites show that global temperatures have been in freefall in recent months. Since September 2024, they have fallen by a full half a degree celsius.

Last month was not even the hottest January, as January 2024 was 0.4C hotter

 

https://www.drroyspencer.com/latest-global-temperatures/

Scientists have now said that much of the recent spike in temperatures has been caused by reduced sulfate emissions from shipping, thanks to new clean air regulations.

Wildfires

The BBC lead their article with a photo of the LA wildfires. The impression, which they clearly want to create, is that these fires are connected to global temperatures.

It proves that their whole article cannot be taken seriously.

Drying and rewetting cycles substantially increased soil CO2 release

by Niigata University, Feb 5, 2025 in ScienceDaily


Soil incubation experiments revealed a comprehensive increase in CO2 release by drying-rewetting cycles (DWCs) among Japanese forests and pastureland soils, suggesting a significant contribution of the DWCs-induced destruction of microbial cells and reactive metal-organic matter complex to the CO2 release increase.
The research group revealed that the amount of CO2 released from soil increases significantly due to repeated drying and rewetting cycles (DWCs) expected to be caused by changes in precipitation patterns due to global warming.

New Study: Sea Levels Around Japan Are ‘Not Rising, Nor Accelerating’ Since The 1800s

by K. Richard, Feb 4, 2025 in NoTricksZone

In a region of the world where tide gauges are not compromised by land subsidence or uplift, sea levels have not been observed to be rising since measurements began in 1894.

According to a new study, when sea levels rise it usually has more to do with declining land movement (subsidence) or 20- to 60-year oscillations than it has to do with thermostatic sea level change.

“In Japan, there are many long-term trend tide gauges recording the sea levels since 1894. The tide gauges of Hosojima, Wajima, Tonoura, and Oshoro, not suffering from subsidence or isostasy, show multi-decadal fluctuations of periodicity quasi-20 and quasi-60 years, but not rising, nor accelerating, relative sea levels.”

Another study published earlier in the year by the same author (Boretti, 2024) indicates the sea level pattern around Japan is similarly occurring around the Polynesian island of Tuvalu.

Sea level changes are said to be influenced more by multi-decadal oscillations and land subsidence than by a global change in the amount of water stored in ocean basins.

“The significant increase in sea level observed at Tuvalu’s current tide gauge is attributed more to multidecadal oscillations, significantly affecting short-term records, and the subsidence of the tide gauge, rather than the global thermosteric contribution.”

“The suggested analysis aligns with prior research, reinforcing the perspective that the sea levels are gently rising and the surfaced area of Pacific islands and atolls is not diminishing, contrary to inaccuracies found in selective studies that emphasize certain data while disregarding others.”

Climate Alarmist Stefan Rahmstorf Struggles With The Reality Of Uncertainty

by P. Gosselin, Feb 2, 2025 in NoTricksZone


By Frank Bosse

(Translated from the original at Klimanachrichten)

We have kept you, dear readers, very promptly informed about AMOC conjectures.

Recently, we also informed you about a new study that found a stable Atlantic overturning circulation since the 1960s. It is not the only one in the recent past.

However, Prof. Stefan Rahmstorf from the Potsdam Institute for Climate Impact Research (PIK) is a great advocate of the “The Day after Tomorrow” scenario of a collapsing oceanic current. As recently as June, 2024, he noted on X (formerly Twitter) that the AMOC mitigation saga “is even more dramatic than it ever was”.

He himself had been responsible for a whole series of papers as author or co-author, which also contributed to the scenario, and he initiated an “open letter” in the fall of 2024 that dramatically addressed politicians. We also reported on this.

Of course, the new findings could not couldn’t pass him by without comment. Under the headline “The AMOC is slowing down, is stable, yes, no, no, yes…” he commented on it on the blog “Real Climate”, which is run by scientists, including himself, Gavin Schmidt from NASA, and others.

What he has to say there can be stated in a nutshell: He defends his approaches and lists the problems of the more recent studies. That was to be expected. For example, he emphasizes that the new climate models (CMIP 6) hardly show any connection between “his fingerprint”, the sea surface temperatures of the “warming hole” in the North Atlantic (see the article here from 17 January 2025) and the actual current, but that the approximately 4 years older ones called CMIP5 do. He also questions whether the new ones are really more reliable in this respect than the older ones. However, the effort for the former was considerable.

He summarized:

I don’t believe that the newer methods are more reliable than the old ones (his, the author). … However, since we don’t have measurements going back far enough, there is still some uncertainty in this respect

California Blows It Again

by W. Eschenbach, Fab 3, 2025 in WUWT


Encouraged by the reception of my previous post “Eight Ten-Thousandths Of A Degree Per Gigaton“, which ranged from warm acceptance through amused contempt to outright hostility, I’ve expanded my research to analyze the CO2 emissions of the late great State of California.

In my post linked above, I found that IF the IPCC is correct (which is a big “IF”), for each gigaton (Gt) of avoided CO2 emissions, there is an avoided global warming of 0.0008°C. Please read that post for the detailed calculations.

And utilizing that relationship, here are the past and projected future California CO2 emissions.

WOW! For all of our sacrifices here in California, for all the money we’ve spent and are projected to spend, we MIGHT cool the world twenty years from now by 0.006°C … be still, my beating heart …

Now, as to how much that has cost and will cost, the numbers are hard to come by. Here are some major costs:

• The California solar mandate is estimated to increase the cost of newly constructed single-family homes by approximately $8,400 each. There are ~ 60,000 new single-family homes built each year in California. That’s about half a billion dollars per year for the next 20 years until 2045, or $10 billion total.

• The “Renewable Mandates” and rooftop solar subsidies have made current California electricity about $0.15 per kWh more expensive than its neighbors. Average since 2004 is about $0.10 per kWh more expensive. California’s annual electricity consumption in 2023 was approximately 287,220,000,000 kWh. That’s a cost of $35 billion per year times 20 years (2025-2045) equals $700 billion, plus $29 billion times 20 years (2004-2024) gives a total of $1.3 TRILLION. And that’s with the totally unrealistic assumption of no increase in either consumption or electricity costs.

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:

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.

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

by P. Homewood, Jan 5, 2025 in NotaLotofPeopleKnowThat


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.”
