Old carbon routed from land to the atmosphere by global river systems

by J.F. Dean et al., June 4, 2025 in Nature

Abstract

Rivers and streams are an important pathway in the global carbon cycle, releasing carbon dioxide (CO2) and methane (CH4) from their water surfaces to the atmosphere1,2. Until now, CO2 and CH4 emitted from rivers were thought to be predominantly derived from recent (sub-decadal) biomass production and, thus, part of ecosystem respiration3,4,5,6. Here we combine new and published measurements to create a global database of the radiocarbon content of river dissolved inorganic carbon (DIC), CO2 and CH4. Isotopic mass balance of our database suggests that 59 ± 17% of global river CO2 emissions are derived from old carbon (millennial or older), the release of which is linked to river catchment lithology and biome. This previously unrecognized release of old, pre-industrial-aged carbon to the atmosphere from long-term soil, sediment and geologic carbon stores through lateral hydrological routing equates to 1.2 ± 0.3 Pg C year−1, similar in magnitude to terrestrial net ecosystem exchange. A consequence of this flux is a greater than expected net loss of carbon from aged organic matter stores on land. This requires a reassessment of the fate of anthropogenic carbon in terrestrial systems and in global carbon cycle budgets and models.

Study finds Southern Ocean’s surface is becoming saltier and losing sea ice, not experiencing an ‘ocean current reversal’

by ScienceFeedback, July, 2025

KEY TAKEAWAY

Recent articles and social media posts inaccurately summarized findings from a June 2025 PNAS paper by claiming that a ‘major current in the Southern Ocean has reversed’. In reality, the PNAS paper does not mention any ‘ocean current reversal’. Instead, the paper mentions a ‘reversal’ of a decades-long trend: the Southern Ocean’s surface is now becoming saltier, instead of ‘fresher’. A saltier ocean surface can speed up the melting of Antarctic sea ice – floating ice which surrounds Antarctica – by drawing heat in the ocean upward toward the ice. This trend surprised scientists in the study, given that prior observations show the Southern Ocean’s surface becoming fresher (less salty) since the 1980s.

Most Americans Still Aren’t Buying Climate Hysteria

by D. Harsanyl, July 16, 2025 in ClimateChangeDispatch 

Climate alarmism hasn’t worked. Here’s why the public tuned it out.

The public awareness campaign to convince Americans that climate change is an existential threat has been an epic failure. [emphasis, links added]

In a recent segment, “Are Americans Afraid of Climate Change?” CNN’s Harry Enten incredulously noted that despite all “the bad weather” we’ve been seeing, only “40% of Americans are greatly worried about climate change. The same as in 2000!”

Why are climate activists losing?

Sooner or later, fearmongering becomes noise. Reality crashes against predictions.

Public schools, institutions of higher learning, governments, international organizations, the whole culture, and scientific institutions have spent billions and untold hours trying to normalize the idea that modernity and capitalistic gluttony have driven temperatures to dangerous extremes.

When I was growing up, it was cooling. Now, it’s warming. And with each surge of alarmism, the message depreciates.

New Study: Africa’s Atlantic Coast Sea Levels Were Still 1 Meter Higher Than Today 2000 Years Ago

by K. Richard, July 14 2025, in NoTricksZone 

The narrative that says relative sea level changes are driven by variations in atmospheric CO2 concentrations has taken another hit.

Before relative sea level (RSL) declined to its present position over the last millennium, Africa’s Atlantic coast RSL ranged anywhere from 0.8 to 4 meters higher than today between 5000 and 1700 years ago (Vacchi et al., 2025).

This Mid- to Late-Holocene RSL highstand was “mainly controlled by the deglaciation history” − meltwater contributions from Earth’s ice sheets and glaciers. Because the climate was so much warmer than today at that time, there was significantly less water locked up on land as ice.

The Antarctic Thermal Optimum “simulated melt of the western Antarctic ice sheet until 2.0 ka BP.” Consequently, sea levels were still ≥ 1 meter higher than present during the Roman Warm Period

“Between -15°N and -0°…data indicate RSL reached its maximal elevation above the present sea level in the late Holocene (~2.0 to ~1.7 ka BP).”

Gardi Sugdub’s ‘Climate Exodus’ Myth: Overcrowding, Not Rising Seas, Drives Relocation

by H. Sterling Burnett, June 27, 2025 in WUWT

Yahoo News recently posted an article from the environmental website The Cool Down claiming that the native residents of the very small Panamanian island, Gardí Sugdub (also known as Cartí Sugdupu), are being forced to flee due to fast rising sea levels swamping the land as a result of climate change. This is false. Sea levels at Gardi Sugdub aren’t rising unusually fast, and the best evidence is that most of the island’s residents are voluntarily abandoning it with government help due to overcrowding and insufficient services and infrastructure on the small island.

Grace Howarth, the author of the article, “Residents forced to flee from ‘disappearing island’ due to heartbreaking crisis: ‘There were no more friends, no more kids playing,’” writes describing the situation there:

Rising sea levels are splitting communities apart in Gardí Sugdub and leaving people behind, possibly in danger.

. . .

One year ago, around 1,200 Indigenous Guna people were transported to the mainland by the Panama government for their safety as ocean waters encroached upon their community.

Climate Realism debunked an earlier article from the BBC making the same claims in February of this year; nothing has changed in the four months since then.

Basic Physics All at Sea in Sky News Climate Scare Nonsense Story

by C. Morrison, May 31, 2025 in WUWT

Possibly one of the dumbest and most scientifically illiterate climate scare stories ever written has been published by the fast-fading UK Sky News. Climate reporter Victoria Seabrook notes that the sea ice on the Arctic “continent” is melting at 12% every decade but she backs it up by publishing a graph clearly showing it has been stable since 2007. She goes on to claim that the Arctic melt will push up sea levels around Britain and fuel worse coastal flooding, seemingly unaware that melting ice in liquid does not raise its level (suggested educational tip, check out ice in a gin and tonic glass). Just for good measure, her silly story throws in the wobbling jet stream and a “shocking” prediction that global temperature could rise by nearly 1°C in just five years.

This story is a classic of its kind – late climate psychosis folderol to back up the collapsing Net Zero fantasy. After decades of relentless mainstream gaslighting, mass audiences are still vaguely concerned that the climate is in some kind of ‘emergency’. Net Zero is retreating around the world, partly because it is increasingly understood that human civilisation cannot abolish the use of hydrocarbons without returning to the dark ages, and partly because nobody is prepared to pay for it when given a choice. But the great climate science con that is the foundation of the collectivist Net Zero lunacy continues, and, if Seabrook’s latest work is an example, it is getting more desperate by the day.

So she publishes the graph below with the misleading 12% decline every decade heading.

Germany’s Scorching Summer of 1911 Undermines Today’s Heat Hysteria

by P. Gosselin, June 03, 2025 in ClimateChangeDispatch

Escaping The Heat
The German blog site lokalgeschichte examines the German summer of 1911, which was exceptionally hot, dry, and sunny. It disproves the previously widespread idea that Central Europe’s heat waves are something new and caused by more CO2 in the atmosphere. [emphasis, links added]

Although temperatures in the summer of 1911 were very high in places (up to 40°C [104°F] in Chemnitz), no new records were broken. The year 1892 had similar or even higher values (41.5°C [106.7°F] in Reichenhall).

The most remarkable feature of the summer of 1911 was not the absolute maximum temperature, but the duration of the hot spell and the persistent tendency towards dry and warm high-pressure weather, which lasted from spring until well into September.

In 1911, Germany saw extreme drought, particularly in western and central Germany. In Berlin, for example, only about half of the normal precipitation fell between April and July, and only a seventh in August.

Such an event occurring today would have climate alarmists blaming CO2.

Nigeria’s Water Crisis: Why Poor Management, Not Climate Change, Is Drying Up Farms

by L. Lueken, May 21, 2025 in WUWT

AfricaNews (AN), in collaboration with the Associated Press, recently posted an article claiming that recent drought in Nigeria is due to climate change. This is unlikely to be the full story. Although data is sparse for the region, human activities are just as likely to be contributing to desertification as cycles of drought are.

The article, “Nigerian farmers struggle as climate change dries up water sources,” claims that climate change is the cause of recent drought in Nigeria, leading to crop declines. Surface water is becoming scarce during the dry seasons, so some farmers are forced to dig wells to irrigate their crops. AN writes that “[r]iverbeds have started to run dry,” and so the blame “is pointed firmly at climate change, with conservationists warning that food could become scarce if measures are not urgently put in place to help the farmers irrigate their land.”

While it is true that Nigeria has been suffering from extended drought, particularly in the northern part of the country, it is not clear that this is all or even mostly because of any human-caused climate change due to changing temperatures. Natural drought, combined with human error in land and water management, seems to be the more likely culprit.

According to the article, over 80 percent of Nigeria’s farmers are smallholder farmers, and they make up 90 percent of the nation’s crop production. The article points at maize (corn) as a sample crop that is suffering due to the water shortage, it “saw a decline in cultivated land from 6.2 million hectares in 2021 to 5.8 million hectares in 2022.”

Crop production data from the United Nations Food and Agriculture Organization (FAO) show that Nigeria’s corn production has been increasing over time. It actually shot upwards the most in recent decades, after remaining relatively flat through the 1980s. Between just 1990 and 2023, Nigerian corn production increased 91 percent, while yields increased 71 percent. (See figure below)

Live at 1 p.m. Eastern: SHOCK CLIMATE REPORT! Urban Heat Islands Responsible for 65% of Global Warming

by C. Rotter, May 16, 2025 in WUWT

The Heartland Institute

A new study from the University of Alabama in Huntsville addresses the question of how much the Urban Heat Island (UHI) effect is responsible for the higher temperatures at weather stations across the world. Dr. Roy Spencer and Dr. John Christy have spent several years developing a novel method that quantifies, for the first time, the average UHI warming effects related to population density. Their finding: no less than 65% of “runaway global warming” is not caused by our emissions of carbon dioxide, but by the urbanization of the world.

Dr. Spencer will join us to go over his findings. We’ll also cover the Crazy Climate News of the Week, including an absurd new bit of unscientific propaganda from the U.S. Climate Reference Network at NOAA, wonder if the sun is setting on wide-scale solar energy, and discuss how alarmists refuse to see that we live in a climactic “golden age”—and more.

Join Heartland’s Anthony Watts, Linnea Lueken, H. Sterling Burnett, Jim Lakely, and Dr. Roy Spencer LIVE at 1 p.m. ET for Episode #157 of The Climate Realism Show. We’ll be answering questions in the chat for us, and for Dr. Spencer, on the show.

James Hansen: Climate Cassandra or Science Salesman?

by C. Rotter, May 15, 2025 in WUWT

One would think that James Hansen—once lionized as the father of modern climate alarmism—might bask in the limelight after a fresh round of histrionics about Earth hurtling toward a “point of no return.” Instead, we find him on the pages of his latest blog-style polemic, “Large Cloud Feedback Confirms High Climate Sensitivity”, complaining that he’s being ostracized by the very media and institutions he helped train to bark on command every time the CO2 concentration ticks up another ppm.

“A strange phenomenon occurred… almost uniformly, these reports dismissed our conclusions as a fringe opinion… Are there important repercussions for the public… indeed, for the future of all people? The answer… is ‘yes.’”

https://www.columbia.edu/~jeh1/mailings/2025/CloudFeedback.13May2025.pdf

One might suggest that after decades of theatrics, people have simply stopped buying tickets to the same show.

But let’s not be hasty. His newest round of publications deserves scrutiny, not for its recycled gloom, but for the increasingly acrobatic logic and interpretive liberties embedded within.

The ‘Big FXcking Deal’ and the Cloud Feedback Feedback

At the heart of Hansen’s thesis is the observed decrease in Earth’s albedo—the fraction of sunlight reflected back into space. Hansen pegs this decline at 0.5% over the last two decades, translating to a 1.7 W/m² increase in absorbed solar radiation. This, he insists, proves that cloud feedback must be large and positive, confirming an equilibrium climate sensitivity of 4.5°C ± 0.5°C for doubled CO2.

“Earth’s albedo… has decreased about 0.5%… we described this change as a BFD… because it has staggering implications.”

The Media Hype Extreme Weather—But Data Tells A Different Tale

by K&K Media, May 14 2025 in ClimateChangeDispatch

Hurricane Winds
These days, stories of extreme weather are everywhere you look. But a crucial detail often goes overlooked: We’re safer from the consequences of that weather than ever before. [emphasis, links added]

There was a time when extreme weather events that led to massive fatalities were depressingly common in the U.S.

In the last 85 years, however, there have only been three such events that took over 1,000 lives: Hurricane Katrina, Hurricane Maria, and a 1980 heatwave.

…

There’s a reason for that.

The most important factor in determining a natural disaster’s destructiveness isn’t its intensity, but how well people in its path are protected. And on that front, things have improved … a lot.

Better building codes have prevented about $1.6 billion in damage a year since 2000. Advances in hurricane forecasts and early-warning systems have given people more time to prepare.

Having air conditioners in nearly 90% of American homes has severely cut the risk of extreme heat.

And while you often hear that the economic damages from extreme weather are growing, you don’t often hear why.

The stated aim, following the Paris Agreements (COP, 2015), is a totally carbon-free world by2050, given the potential danger posed to the planet by atmospheric CO2. As with my recent text on the Green Pact, the role of this gas is not discussed here and therefore is not thesubject of this article.

How Wind And Solar Sent Energy Prices Sky-High in ‘Green’ Countries

by B. Lomborg, May 8, 2025 in ClimateChangeDispatch 

Ask families in Germany and the UK what happens when more and more supposedly “cheap” solar and wind power is added to the national power mix, and they can tell you by looking at their utility bills: It gets far more expensive. [emphasis, links added]

The idea that power should get cheaper as we get more green energy is only true if we exclusively use electricity when the sun is shining and the wind is blowing.

But modern societies need power around the clock. When there is no sun and wind, green energy needs plenty of backup, often powered by fossil fuels. What this means is that we pay for not one but two power systems.

And as the backup fossil fuel power sources are used less, they 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.

One study looking at China showed that the real cost of solar power on average turns out to be twice as high as coal, while a peer-reviewed study of Germany and Texas shows solar and wind are many times more expensive than fossil fuels.

Germany and the UK now have so much “low-cost” solar and wind that their electricity costs have become among the world’s most expensive.

The latest data from the International Energy Agency make it clear that there is a strong and clear correlation between more solar and wind and much higher average energy prices for households and industries.

In a country with little or no solar and wind, the average electricity cost is a bit over 11¢ per kilowatt-hour.

For every 10 percentage points of solar and wind, the cost increases by more than 4¢. The results are nearly similar for 2019, before any impacts of COVID and the Ukraine war.

Look at Germany, where 34¢ per kWh is more than twice the US cost and nearly four times the Chinese price.

Countries that use a higher percentage of solar and wind power tend to have higher energy prices per household. Mike Guillen/NY Post Design

Germany has installed so much solar and wind that, at full capacity, it could produce two times Germany’s electricity demand.

Phys.org Editorial Falsely Links Hurricanes To ‘Widespread’ School Closures

by A. Watts, May 06, 2025 in ClimateChangeDispatch 

school closed storm damage
In a recent editorial published by Phys.org, researchers claim that climate change is driving more powerful and frequent hurricanes, which in turn are causing widespread school closures, labeling it an “overlooked consequence” of our supposedly worsening climate. [emphasis, links added]

This narrative is false.

The available data shows no trend of increasing hurricane frequency or intensity due to human-induced climate change, and if the storms themselves aren’t worsening, the claim that they are causing more missed school days due to climate change collapses under its own weight.

The central claim that hurricanes are becoming more destructive and frequent due to climate change is contradicted by both long-term observational data and the official position of major scientific institutions.

According to the National Oceanic and Atmospheric Administration’s (NOAA) Geophysical Fluid Dynamics Laboratory (GFDL), there is no strong evidence of an increase in either the number or intensity of hurricanes globally due to human-caused climate change.

Antarctica’s Astonishing Rebound: Ice Sheet Grows for the First Time in Decades

by SciTec, Apr 25 2025

The Antarctic Ice Sheet (AIS) plays a major role in global sea-level rise. Since March 2002, the GRACE (Gravity Recovery and Climate Experiment) mission and its successor, GRACE-FO (GRACE Follow-On), have provided valuable data to monitor changes in ice mass across the AIS.

Previous studies have consistently shown a long-term trend of mass loss, particularly in West Antarctica and the Antarctic Peninsula, while glaciers in East Antarctica appeared relatively stable. However, a recent study led by Dr. Wang and Prof. Shen at Tongji University has found a surprising shift: between 2021 and 2023, the AIS experienced a record-breaking increase in overall mass.

Antarctic Ice Sheet’s Mass Drama,From Accelerated Loss to Surprising Gain
Antarctic Ice Sheet mass change series (April 2002–December 2023) derived from GRACE/GRACE-FO satellite gravimetry. Ellipses highlight period-specific mass change rates, while the grey shadow indicates the data gap between missions. Credit: Science China Press

Notably, four major glaciers in the Wilkes Land–Queen Mary Land region of East Antarctica reversed their previous pattern of accelerated mass loss from 2011 to 2020 and instead showed significant mass gain during the 2021 to 2023 period.

Record-breaking mass gain over the Antarctic Ice Sheet

From 2002 to 2010, the AIS has experienced a mass loss with a change rate of –73.79±56.27 Gt/yr, which nearly doubled to –142.06±56.12 Gt/yr for the period 2011–2020. This accelerated mass loss was primarily related to intensified mass depletion in West Antarctica and the WL-QML region of East Antarctica. However, a significant reversal occurred thereafter, driven by anomalous precipitation accumulation, the AIS gained mass at a rate of 107.79±74.90 Gt/yr between 2021 and 2023.

The Hidden Cost Of Net Zero

by P. Homewood, May 8, 2025 in WUWT

UK Electricity Consumption

https://www.gov.uk/government/statistics/electricity-section-5-energy-trends

The REF’s new report on green energy subsidies noted that renewables subsidies are now costing £25.8 bn per year – or over £900 per household annually – about one third of which, £280, will hit the average domestic electricity bill directly.

For a long time, part of the gaslighting around the cost of Net Zero has been focus people’s attention over the impact on their energy bills.

However, as John Constable pointed out, only about a third of the cost hits the public directly via their electricity bills, because only a third of electricity is consumed by domestic users.

The other two thirds is used by industry and commerce, transport and the public sector.

But that does not mean that the public at large don’t end up footing the entire bill one way or another.

Higher electricity costs for industry and commerce mean higher prices in the shops. And higher electricity costs in the public sector mean higher taxes or poorer public services.

At the worst, businesses may shut or move their production abroad, leaving us all worse off.

Miliband and co would love you to think you are only paying a hundred quid or so for Net Zero. People would be horrified to learn that the price is nearer a thousand quid a year.

And that cost is of course just for starters. When we all have to buy expensive EVs and heat pumps we don’t want, we will be much worse off.

Former British PM Tony Blair Slams Net Zero as “Irrational”

The original piece by Tony Blair;

The Climate Paradox: Why We Need to Reset Action on Climate Change

PAPER 29TH APRIL 2025
LINDY FURSMAN

Foreword [By Tony Blair]

People know that the current state of debate over climate change is riven with irrationality. As a result, though most people will accept that climate change is a reality caused by human activity, they’re turning away from the politics of the issue because they believe the proposed solutions are not founded on good policy.

So, in developed countries, voters feel they’re being asked to make financial sacrifices and changes in lifestyle when they know that their impact on global emissions is minimal. Whatever the historical responsibility of the developed world for climate change, those with even a cursory knowledge of the facts understand that in the future the major sources of pollution will come principally from the developing world.

But for that developing world, there is an equal resentment when they’re told the investment is not available for the energy necessary for their development because it is not “green”. They believe, correctly, that they have a right to develop and that those who have already developed using fossil fuels do not have the right to inhibit them from whatever is the most effective way of developing.

Therefore, there has been a period where climate-change action and global agreements, notably the Paris Agreement in 2015, seemed to herald a new era; but that momentum has been followed – exacerbated by external shocks like Covid and the Ukraine war – by a backlash against such action, which threatens to derail the whole agenda.

Climate change and prehistoric human populations: Eastward shift of settlement areas at the end of the last ice age

by University of Cologne, Apr 3, 2025 in ScienceDaily

A new study sheds light on how prehistoric hunter-gatherer populations in Europe coped with climate changes over 12,000 years ago. Led by scientists from the University of Cologne, a team of 25 prehistoric archaeologists from twenty European universities and research institutions revealed significant shifts in population size and density during key periods at the end of the last Ice Age, specifically during the Final Palaeolithic between 14,000 and 11,600 years ago. The study has been published in PLOS One under the title ‘Large scale and regional demographic responses to climatic changes in Europe during the Final Palaeolithic’.

 The results reveal that the first establishment of a larger human population in north-eastern central Europe during the Final Palaeolithic was followed by a dramatic population decline during the last cold period (Greenland Stadial 1) of the Ice Age. This decline reduced the total population of Europe by half. However, the study found that some areas in central Europe show stability or even a slight increase in population size against the general trend. The team interprets this finding as evidence of human migration towards the east in response to worsening climate conditions.

State Of The Great Barrier Reef 2024

by P. Homewood, Mar 14, 2024 in NotaLotofPeopleKnowThat 

The Australian Environment foundation (AEF), which is a farmer friendly conservation group, has issued a new report entitled “State of the Great Barrier Reef 2024.”

Peter Ridd, the Chairman of the AEF, said the report shows that the reef is in excellent condition with record amounts of coral. “Despite all the catastrophism about hot water bleaching events in the last decade, the species most susceptible to bleaching, (the plate and staghorn corals), have exploded in number. Sadly, the impact of bleaching is routinely exaggerated by the media and some science organisations.”

“The impact of farm pollution in the Reef is negligible and all 3000 individual reefs have excellent coral. No other Australian ecosystem has shown such little change in modern times” Ridd said.

Peter Ridd added, “Australia spends roughly $500 million each year to “save the reef” but this money could be much better spent on genuine environmental problems such as control of invasive weeds and feral animals, or restoring indigenous fire practices into forests and rangeland”.

He concluded, “The public is being deceived about the reef. How this occurred is a serious issue for the reef-science community which has embraced emotion, ideology, and raw self-interest to maintain funding”.

“This new report distils a great deal of data about the reef” said Ridd “it is time that the reef

science institutions confront this data rather than ignoring it and hoping nobody will notice. I challenge them to a public science duel – any time any place.”

The Great Barrier Reef is the largest reef system in the world, and scientists have been warning of its imminent demise since the 1960s.

German Droughts Were Much More Common Back In The Old Days, Before 1980!

by P. Gosselin, Apr 23, 2025 in NoTricksZone 

Central Europe has been experiencing a bout of dry weather since February. Germany’s DWD national weather service reported in a recent press release that just 19 liters per square meter (l/m²) fell in March compared to the approx. 60 liters that normally fall in the month. This made last March one of the driest since measurements began in 1881.

“The pronounced drought, which had already lasted in some regions since the beginning or middle of February, was caused by high-pressure areas that repeatedly settled over Central Europe or in the surrounding area,” reports the DWD.

Not surprisingly, the media are making alarmist claims of unprecedented drought, and all hinting it’s due to climate sins by mankind.

Driest years overwhelmingly before 1980

So is drought in rainy Germany something new that we have only begun to experience, like the media and pols suggest?

The historical data show that the answer is clearly NO.

Four of the 5 driest years on record in Germany occurred before 1960. Eight of the top 9 occurred before man-made climate change was ever an issue (before 1980).

In alarmist imaginations, January 2025 was ‘hottest on record’; in reality, it was darned cold

by J. Robson, March 12, 2025 in ClimateRealistsofBritishColumbia

We continue to be baffled by alarmist claims that the long, cold winter of 2024-25 did not happen, is not happening, and must not happen.

Sometimes things occur that surprise us and run contrary to our general understanding of the world, but when they do we notice them and admit them. (Under which heading file that thus far in 2025 Arctic sea ice extent is at its lowest in a decade, the opposite of 2024.)

But what are we to make of “The Science Behind the Hottest January on Record: What It Means for the Future” or “The Impact of Record-Breaking January Temperatures on Global Climate Trends”?

In fact, as we reported recently, the best available satellite data shows a sharp drop in temperature in January. And we recently learned that Ottawa “just had its coldest February since February 2015.” In which it is far from alone, with harsh conditions from here to Central Asia. And we’re not out of the snowy woods yet. But who are you going to believe, data, headlines or your own eyes and frosty toes?

DESPERATELY SEEKING EXPLANATIONS…

If they do admit that it’s happening, and they look a bit silly trying not to, they produce an explanation-like object that lacks a certain rigour. For instance a piece on the topic in the Hindustan Times (oh what a globalized world we live in as MSN delivers us the Delhi take on cold in Timmins) explains that:

“After last month’s polar vortex collapse, a second one is expected to unleash freezing conditions across North America. With the winter weather phenomenon predictions eyeing a mid-March comeback, parts of Canada and the United States could be submerged in deep freezes, possibly even impacting travel as was seen in the previous cycle. The UK and Europe may also end up facing the brunt of the extreme winter weather.”

OK, so what’s with the dreaded warming? Well, the piece goes on for a while about how weird stuff is happening weirdly:

The European Court of Auditors has found that between 2021 and 2023, nongovernmental organizations (NGOs) received a total of €7.4 billion ($8.4B) from the EU, including 4.8 billion euros from the governing Commission and another 2.6 billion euros from member states.

Thousands of NGOs were funded with taxpayer cash to promote so-called EU values and advance left-wing causes on immigration, environmentalism, and even lobbying for the ban on combustion engine cars, Germany’s Focus magazine reported.

The Court of Auditors report, which found that there was “no reliable overview of EU funding granted to NGOs”, raised concerns that some such organizations were disguising themselves as NGOs to lobby politicians on behalf of their economic interests while claiming to be nonprofits, or by government actors using the groups to advance their endsclandestinely.

An unnamed research facility in the textile and cosmetics industry, which claimed to be an NGO to receive EU funding, was identified by the Court of Auditors as having pursued the “business interests of its predominantly for-profit members” while maintaining a nonprofit status.

“Solar Madness In Germany”: Gigawatt-Hours Of Subsidized Electricity Gets Dumped Abroad For Free”

by  P. Gosselin, Apr 16, 2025 in NoTricksZone

Blackout News here reports on how Germany’s uncontrolled solar production without appropriate storage and consumption models is putting a huge burden on the domestic market and consumers.

At the same time, neighboring countries are benefiting from all the free electricity Germany uncontrollably overproduces and consumers just don’t need!

Experts are warning of the collapse of an over-regulated energy system that is increasingly moving away from reality. Germany has significantly expanded its solar PV capacity in recent years. According to the Federal Network Agency (Bundesnetzagentur), the total installed solar PV capacity in Germany reached 99.3 GW at the end of December 2024.

Geothermal electricity generation

by C. Morris, Apr 12, 2025 in WUWT

Geothermal power stations are mature technology with proven performance, reliable operation and ideal for baseload generation. The units are synchronous, so they support the grid.  The production from them is considered by most to be renewable. They do not use fossil fuels to provide the heat. It is not “carbon free”, but no generation truly is. It has a relatively small footprint, environment harm is low, and it can coexist with farming or industrial development. Most developments have a cheaper energy cost than onshore wind, using published accounts for analysis. For countries or areas where the resource is there, geothermal generation is very viable.

The resource

Geothermal power stations are very much a niche generation source (only about 15GW worldwide,  from 673 units at 198 fields according to Google), totally dependent on locality. They are mainly associated with plate boundaries, particularly the Pacific Ring of Fire. Compare the plate boundaries and volcanic activity in Figure 1 with station locations in Figure  2

Associated with the plate boundaries and other weak points in the earth’s crust, the deep underlying heat in the mantle can find its way to the surface easier. “Bubbles” of magma can push up to relatively shallow depths. These may force their way to the actual surface as volcanoes with their lava. With the distortion and earth movement from this activity, the crust’s rock formations are deformed and cracked – earthquakes.  Groundwater can enter all the fault cracking in the rocks. This will be heated up by the hot magma, even if that has solidified.

Geothermal resources exploited for power production are the plumes of hot water formed from the heating of this deep groundwater. In geologic terms, such convection systems are short lived – generally lasting between 200 and 450 thousand years. They end because the heat source has gone or the cracking has been filled by precipitated minerals from the circulating water as it cools. The world is full of solidified magma (granite) and prehistoric geothermal systems. Many of the latter are now mined for gold and other precious materials.
