Global warming, climate change, all these things are just a dream come true for politicians. I deal with evidence and not with frightening computer models because the seeker after truth does not put his faith in any consensus. The road to the truth is long and hard, but this is the road we must follow. People who describe the unprecedented comfort and ease of modern life as a climate disaster, in my opinion have no idea what a real problem is.
Scientists have created the first “anti- spin ice” using colloidal particles that attract each other, inverting the usual ice rule so the system maximizes (rather than minimizes) local topological charges.

Scientists have created the first “anti- spin ice” using colloidal particles that attract each other, inverting the usual ice rule so the system maximizes (rather than minimizes) local topological charges.
This comes from a Nature Communications paper (published September 2026) by Renaud Baillou, Matthew Terkel, Cristiano Nisoli, and Pietro Tierno (University of Barcelona and Los Alamos National Laboratory).
A Phys.org feature summarizing it appeared on November 1, 2026, under the exact headline: Breaking the ice: Scientists use attracting particles to form an anti-spin ice.
Background: ordinary spin ices and the ice rule
Artificial spin ices (and colloidal particle ices) mimic the geometric frustration of water ice.
In water ice, each oxygen has two hydrogens close and two farther away (the “ice rule”). Analogous systems, arrays of nanomagnets or colloidal particles in lattice traps, follow a similar local rule that minimizes topological charge at each vertex (junction).
Because many arrangements satisfy the rule equally well, the systems often remain disordered or show residual entropy. Colloidal versions typically use repulsive paramagnetic particles confined in double- well grooves; repulsion keeps charges as balanced and small as possible.
The anti- spin ice approach
The team inverted the interactions to attractive and isotropic. They used ~2.8 µm paramagnetic polystyrene colloids (with iron-oxide grains) in lithographic elliptical wells, one particle per well.
A fast in- plane rotating magnetic field (typically 1- 50 Hz) induces dipoles that average to net attraction in every direction: head- to- tail attraction is stronger than side- by- side repulsion, yielding isotropic attraction whose strength is tuned by field amplitude.
Under attraction the particles crowd toward some vertices and away from others, so the system maximizes topological charge (e.g., all particles near a vertex or all far away) instead of minimizing it. This breaks the conventional ice rule.
Key results
Bipartite lattices (square, honeycomb): Simulations and experiments show spontaneous symmetry breaking into a staggered “charge crystal”. High positive and high negative charges alternate in a checkerboard-like pattern (a single ordered ground state). This differs from the repulsive case, where the honeycomb lattice is highly degenerate.
Non- bipartite pentaheptite lattice (network of five- and seven- sided polygons): Charge crystallization is frustrated. Even at the strongest attraction, roughly one in four vertices remains low- charge. Odd- sided loops prevent perfect alternation of maximal charges, producing a new form of topological-charge frustration and a degenerate manifold of near- ground states. Experiments on a pentaheptite lattice of ~205 particles matched the simulations.
The work shows that frustration can arise from the inability to maximize charges globally when lattice topology forbids it, not only from the inability to minimize them. Because the interaction sign is controlled by the magnetic-field orientation (a conical field can switch between attraction and repulsion around the “magic angle”~54.7°), the same platform can be programmed to act as either conventional colloidal ice or anti- spin ice. The authors suggest this concept could extend to nanomagnetic, superconducting, or metamaterial artificial-ice systems.
In short, by flipping repulsion to attraction the researchers reversed the organizing principle of spin ice and uncovered both ordered charge crystallization and a novel kind of frustration.

Emergent charge crystallization and frustration in a particle anti-spin ice
Abstract (key points)
Artificial spin ices are versatile platforms for engineering exotic states of matter. They are typically governed by the ice rule, which enforces minimization of local topological charge and often produces degeneracy and constrained disorder.
This work reports the first realization of an “anti- spin ice”: a system in which the ice rule is inverted. The system seeks to maximize (rather than minimize) spin- ice charges.
Method: Fast- rotating in- plane magnetic fields generate isotropic attraction between colloidal particles, reversing the usual repulsive interactions used in colloidal spin ices.
Lattices studied: Bipartite square and honeycomb lattices and non- bipartite pentaheptite geometries (experiments and simulations).
Main findings: Rules for order and disorder in the anti- spin ice are established. On the pentaheptite lattice, a new form of frustration appears, topological charge frustration, arising from networks of unequal, odd- sided polygons that suppress charge crystallization even at high interaction strengths.
Core idea and results
In conventional colloidal particle ice, repulsive paramagnetic colloids in double- well traps follow the ice rule (balanced topological charge at vertices).
Here, a rapidly rotating in- plane magnetic field averages the dipolar interactions into net isotropic attraction. Particles therefore crowd toward some vertices and away from others, maximizing local charges.
Bipartite lattices (square, honeycomb): Spontaneous symmetry breaking produces a staggered “charge crystal” in which high positive and high negative charges alternate. A single ordered ground state emerges in both geometries (in contrast to the highly degenerate honeycomb case under repulsion).
Pentaheptite lattice (5- and 7- sided polygons): Perfect staggered crystallization is topologically impossible. Roughly one- quarter of the vertices remain low- charge even at the strongest attractions tested, producing a degenerate manifold of near-ground states. This is a distinct form of frustration driven by the inability to maximize charge globally.
The interaction sign can be tuned continuously (e.g., via a conical field around the “magic angle” ≈ 54.7°), so the same platform can switch between conventional ice and anti-spin ice behavior.
The authors note that the concept could extend to other artificial- ice platforms (nanomagnetic, superconducting, metamaterial, etc.).

Paper:Emergent charge crystallization and frustration in a particle anti-spin ice
Kīlauea is one of the world’s most active volcanoes and the youngest on the Island of Hawaiʻi. It is in the shield- building stage of Hawaiian volcanism.
Activity is predominantly effusive (fluid Hawaiian- style lava flows and fountains), with occasional explosive events.
This paper presents the highest- resolution seismic images yet of the shallow magma storage system beneath Kīlauea’s summit.

“Mapping Kīlauea’s Magma Reservoirs” is a Research Spotlight by science writer Matthew R. Francis, published in Eos on 3 November 2026 (doi: 10.1029/2026EO260347).
It summarizes a high- resolution seismic tomography study of magma storage beneath the summit of Kīlauea volcano in Hawai‘i.
Researchers (Lin et al.) deployed a dense array of 1,815 small (nodal) seismometers in a roughly 12 km × 12 km mesh at Kīlauea’s summit.
They combined recordings of natural earthquakes with controlled seismic signals from a large vibroseis truck (“T-Rex”) that generates artificial vibrations. This hybrid passive and active- source approach produced millions of P- and S- wave arrivals.
Joint inversion of the travel- time data yielded 3- D models of P- wave velocity (Vp), S- wave velocity (Vs), and Vp/Vs ratio in the upper ~4 km (relative to sea level), on a 500 m grid. Resolution tests showed recovery of sub- kilometer to kilometer- scale structure.
The models clearly image two principal magma storage regions, each roughly 2 km across:
One beneath Halemaʻumaʻu crater (in the main caldera).
One beneath the south caldera.
Both appear as localized zones of reduced Vs (and moderately reduced Vp) with elevated Vp/Vs at depths of about 1- 3 km below sea level.
These anomalies are laterally distinct near the surface but appear to merge into a broader low- velocity zone at greater depth. Higher- velocity rock surrounding them is interpreted as stronger intrusive complexes that help confine the magma.
The seismic anomalies spatially match independent geodetic models of deformation sources, supporting the magma- reservoir interpretation.
Despite decades of monitoring, previous seismic images of Kīlauea’s summit plumbing lacked the resolution needed to sharply delineate individual reservoirs because of sparse sensor coverage.
The new hybrid dense- array approach overcomes that limitation and provides an improved framework for understanding magma storage and transport. The authors note that the methodology has already proved useful in other Kīlauea studies and could be applied at other active volcanoes.
The Eos article is a concise, accessible summary rather than the full technical paper; the original research contains the detailed models, resolution tests, and comparisons with geodetic data.
Kīlauea is one of the world’s most active volcanoes and the youngest on the Island of Hawaiʻi. It is in the shield- building stage of Hawaiian volcanism.
Written records begin around 1823 (after missionary William Ellis visited the summit), though oral histories and geologic evidence extend much further back.
Activity is predominantly effusive (fluid Hawaiian- style lava flows and fountains), with occasional explosive events.
Geologic records show frequent summit and rift- zone eruptions over millennia. Explosive phases occurred in the past, including a major event around 1790 (Keanakākoʻi Ash) that killed hundreds (part of a warrior party) and left preserved footprints in ash deposits
From the early 1800s until 1924, activity was nearly continuous at the summit caldera (Kaluapele), often featuring lava lakes in Halemaʻumaʻu. Major overflows filled parts of the caldera. Notable early events include the 1823 Southwest Rift Zone eruption and the 1840 East Rift Zone eruption.
20th Century Highlights
1924: A series of powerful steam explosions (phreatic) in Halemaʻumaʻu ejected rocks and ash; one person was killed. This ended the long period of continuous summit lava- lake activity.
1934– 1952: Quiet period (nearly 18 years of inactivity).
1952: Summit eruption in Halemaʻumaʻu (June– November) with lava fountains, ending the long quiescence.
1955: Lower East Rift Zone (Puna) eruption, first there since 1840, opened multiple vents and destroyed property.
1959: Spectacular Kīlauea Iki eruption with fountains up to ~580 m (1,900 ft).
1960: Kapoho eruption on the lower East Rift Zone destroyed the village of Kapoho.
1969–1974: Maunaulu (East Rift Zone) eruption, one of the longest and most voluminous flank eruptions of the prior 2,200 years.
Other short summit and rift eruptions occurred through the 1960s- 1970s and early 1980s.
The Long Puʻuʻōʻō Eruption (1983– 2018)
This was Kīlauea’s longest and most voluminous historical East Rift Zone eruption (over 35 years). It began on January 3, 1983, with fissures that focused at Puʻuʻōʻō (and later Kupaianaha). It produced ~4.4 km³ of lava, covered >140 km², added new land to the coastline, and destroyed over 200 structures (including much of Kalapana in 1990). Activity was nearly continuous, with pauses of weeks to months.
From 2008 to 2018, a concurrent summit lava lake existed in a new vent within Halemaʻumaʻu, producing a persistent gas plume.
2018 Lower East Rift Zone Eruption and Summit Collapse
In May 2018, magma drained from the summit and Puʻuʻōʻō into the lower East Rift Zone (Leilani Estates area). This produced the largest and most destructive eruption in at least 200 years: ~1 km³ of lava, dozens of fissures, destruction of ~700 structures, and a magnitude- 6.9 earthquake. The summit caldera collapsed in stages (deepening Halemaʻumaʻu by hundreds of meters). The eruption ended in early August 2018.
Post- 2018 Activity (Reawakening)
After a quiet period, activity resumed:
December 2020- May 2021: First post-2018 summit eruption in Halemaʻumaʻu (boiled off a water lake that had formed in the collapse pit).
September 2021- December 2022 (or into 2023 in some accounts): Longer summit eruption filling more of the deepened crater.
Additional short summit eruptions in 2023 (e.g., January, June, September).
June 3, 2024: Brief (~8.5-hour) Southwest Rift Zone eruption.
September 15- 20, 2024: Nāpau Crater eruption on the middle East Rift Zone (first ERZ eruption since 2018).
An episodic lava- fountaining eruption began on December 23, 2024, in Halemaʻumaʻu. By mid- to- late October 2026 it had produced at least 55 episodes of high fountaining (peaks exceeding 500 m / ~1,640- 1,770 ft in some episodes), with pauses of days to nearly two months.
Lava has raised the crater floor significantly (over 100 m in places) but remains contained within the caldera. Scientists use summit tilt (inflation, deflation) to forecast episode windows. As of early November 2026, activity continued with overflows and reinflation after episode 55 (October 17, 2026).
Kīlauea’s eruptions are closely monitored by the USGS Hawaiian Volcano Observatory. Patterns often involve magma storage in summit reservoirs (Halemaʻumaʻu and south caldera) that feed both summit and rift- zone activity. For the absolute latest status, check the USGS HVO website, as conditions can change rapidly.
High-Resolution Body-Wave Tomography of Kı̄lauea’s Summit Magma Storage System From a Dense Passive and Active Source Experiment
This paper presents the highest- resolution seismic images yet of the shallow magma storage system beneath Kīlauea’s summit.
The authors conducted a 37- day hybrid seismic experiment in May- June 2023 that combined a very dense array of nodal seismometers with controlled-source (vibroseis) signals.
Experiment Design
1,815 three- component nodal seismometers deployed in a ~12 times 12 km mesh across the summit and caldera.
396 vibroseis source positions using a large T- Rex vibroseis truck that generated controlled seismic vibrations.
Combined with natural local earthquakes.
Resulted in ~15 million P- and S- wave arrivals
Methods and Results
Joint inversion of the earthquake and active- source travel times produced 3- D models of:
Compressional- wave velocity (Vp)
Shear -wave velocity (Vs)
Vp/Vs ratio
Models cover the upper ~4 km (relative to mean sea level) on a 500 m grid. Resolution tests confirm recovery of sub- kilometer to kilometer- scale features.
Key findings:
Two principal magma storage regions, each ~2 km across:
Beneath Halemaʻumaʻu crater
Beneath the south caldera
Both appear as zones of reduced Vs (and moderately reduced Vp) with elevated Vp/Vs at depths of 1- 3 km below sea level.
The anomalies are laterally distinct at shallow levels but appear to merge into a broader low- velocity zone at greater depth.
Surrounding higher- velocity rock is interpreted as stronger intrusive complexes that help confine the magma.
The seismic anomalies spatially match independent geodetic (deformation) models of magma reservoirs, supporting the interpretation.
Previous seismic images lacked the resolution to clearly separate individual reservoirs because of sparse permanent station coverage.
This hybrid dense- array approach overcomes that limitation and provides a much sharper view of how magma is stored and potentially connected beneath the summit.
The authors note that the methodology can be applied at other active volcanoes.
The images show magma stored in two regions. One under Halemaʻumaʻu is consistent with hot, fractured rock that may contain magma and gases.
The second under the south caldera is more confined. They are separate near the surface but may link deeper. Higher- velocity rock around them acts as a mechanical boundary.
Imaging magma storage beneath active calderas requires resolving crustal structure at scales comparable to those of individual reservoirs. To identify potential reservoirs beneath Kı̄lauea, Hawai’i, we conducted a hybrid seismic experiment at its summit for 37 days in 2023 that combined more than 1,800 three-component nodal seismometers with 396 vibroseis source positions, yielding about 15 million 𝑃– and 𝑆-wave arrivals. Joint inversion of earthquake and active-source travel times yields three-dimensional models of 𝑉𝑝, 𝑉𝑠, and 𝑉𝑝/𝑉𝑠 within the upper ∼4 km beneath the summit relative to mean sea level, parameterized on a 500 m grid, within which the resolution tests demonstrate recovery of sub-kilometer to kilometer-scale structure. The models delineate two principal magma storage regions beneath Halema’uma’u and the south caldera, each on the order of 2 km across. Both reservoirs are expressed as localized zones of reduced 𝑉𝑠 and moderately reduced 𝑉𝑝 with locally elevated 𝑉𝑝/𝑉𝑠 at depths of 1–3 km below sea level. The anomalies are laterally distinct at shallow levels but appear to merge within a broader zone of reduced velocities at depth. Surrounding higher-velocity domains likely represent mechanically stronger intrusive complexes that confine magma storage. Spatial correspondence between seismic velocity anomalies and independently modeled geodetic deformation sources supports the interpretation that the imaged structures represent magma storage regions. These results demonstrate that dense nodal arrays combined with hybrid passive-active tomography can resolve reservoir-scale structure at active volcanoes and provide an improved framework for interpreting magma storage and transport beneath Kı̄lauea.
Rupert Darwall, previously special adviser to the UK’s then-Chancellor of the Exchequer Norman Lamont and currently Senior Fellow at the National Center for Energy Analytics (NCEA), has spent the better part of two decades doing what few writers on climate policy dare to do: following the money, the meetings and the memoranda behind the West’s great green crusade.
Rupert Darwall, previously special adviser to the UK’s then-Chancellor of the Exchequer Norman Lamont and currently Senior Fellow at the National Center for Energy Analytics (NCEA), has spent the better part of two decades doing what few writers on climate policy dare to do: following the money, the meetings and the memoranda behind the West’s great green crusade. The Age of Error, newly published, is his most ambitious book (out of three) yet. It attempts nothing less than an explanation of why the West – with the significant exception of Trump’s America – chose to disarm itself economically, energetically and militarily at the very moment big-power geopolitics returned with a vengeance. The book is sweeping in its coverage of world events, learned in its focus on key issues, often brilliant in untangling the machinations that occur in the corridors of power. Yet, in one crucial respect, it is curiously conventional.
From Lehman to L’Aquila
Darwall’s age of error begins with the 2008 financial crisis. Elected politicians lost the authority to govern on their own account. Drawing on Bertrand de Jouvenel, Darwall argues that they recovered it by borrowing the prestige of experts: central bankers, climate scientists and public health officials. The result was what he calls “the co-dependency of politicians and experts with its command to ‘follow the science’”. Decisions migrated from parliaments to unelected committees (quangos in British parlance), and dissent became heresy.
The central bankers went first. Deficit financing and near-zero interest rates were supposed to restore growth; the Bank of England alone bought close to £900 billion of assets. Growth never properly resumed. What came instead were zombie firms, inflated asset prices, stalled productivity and, eventually, the inflation of 2021–22 that the monetary mandarins failed to see coming. Darwall reads this as a Keynesian conceit, the opposite of Schumpeter’s creative destruction of a vibrant capitalism. The real supply-side miracle of the period came not from Threadneedle Street or the Federal Reserve but from the shale fields of Texas and North Dakota, despite the Obama administration’s hostility to fracking.
Easy money had a further consequence. “Easy money begat ESG,” Darwall writes. Cheap capital disguised the true cost of capital-intensive wind and solar, while Wall Street embraced environmental, social and governance investing to buy itself a social licence after the crash. Mark Carney’s campaign to turn central banks into climate regulators, which I criticised at the time, and the fatal combination of central banking and ESG that followed, belong to the same story. Markets killed ESG in 2022, as Darwall wryly observes, although the regulators in the EU have not got the message, as I noted recently.
The intellectual spine of the book is the West’s abandonment of energy realism. Darwall contrasts the St Petersburg G8 of 2006 with the L’Aquila G8 summit of 2009. The 2006 G8 was the last occasion on which Western leaders spoke collectively as members of a fossil-fuelled civilisation focused on energy security. In 2009, the G8 inaugurated “an era of green Keynesianism”, promising emissions cuts of 80% or more by 2050 while claiming that green stimulus would deliver “sustainable growth”. “It was a jumble of policy incoherence,” Darwall writes. It was also a programme to replace efficient energy with inefficient energy, reversing the trajectory of progress since the industrial revolution.
The climate juggernaut, dissected
Darwall is unrivalled in explaining the anatomy of the UN climate process. His account of the small island states as climate ‘martyrs’ is a gem. The poster-child image of the Maldives vanishing beneath the waves served NGOs and island diplomats well. It helped win both the 1.5°C target and the $100 billion climate finance pledge. Yet a 2015 study of a central Pacific atoll that Darwall cites found that “no islands have been lost, the majority have enlarged”. Politics, as he says, “led the science”.
His account of the Paris agreement is equally penetrating. “NGOs turned out to be the most powerful players at the Paris COP.” The formula of Net Zero by 2050 had first been pitched to Obama’s climate envoy, Todd Stern, over an “eye-wateringly expensive tea in London”. “Adopting the goal of Net Zero would be the self-inflicted price the West paid for obtaining a climate agreement at Paris,” Darwall writes. China, meanwhile, kept building coal plants and captured the supply chains of the very ‘green’ industries the West subsidised. Far from liberalising China, WTO membership meant that “America and the West had invited a tiger to eat their lunch”. The belief that climate change poses an existential threat, Darwall concludes, “is an artefact of the Western mind in thrall to an ideology – environmentalism”.
The British chapters will be painful reading for anyone who still believes Westminster governs in the national interest. In June 2019, a lame-duck Theresa May made Net Zero law by statutory instrument, approved after an 88-minute Commons debate without a vote. Her Chancellor Philip Hammond had warned that the cost would be “well in excess of a trillion pounds”. Darwall’s data show a 20.7% increase in British generating capacity producing 24.2% less electricity. “Producing less with more is the essential fact of the energy transition,” he writes. Britain now pays the highest electricity prices in the industrialised world. The folly of ‘climate leadership’ by a country with less than 1% of global emissions is a theme I have covered in these pages.
On the WHO-declared Covid pandemic, Darwall is unsparing. The cover-up of the virus’s origins “has every claim to be the greatest crime in the history of science”, and even the CIA now judges a laboratory origin more likely. His parallels between ‘The Science’ of climate and of the pandemic, from the censorship of dissent to the freezing out of advisers such as William Happer (on climate) and Scott Atlas (on public health), are insightful and right on the mark.
Darwall reads Donald Trump’s election as the populist revolt against all this. “Trump’s re-election killed climate catastrophism as a political force,” he writes. Trump told the UN General Assembly that climate change was “the greatest con job ever perpetrated on the world”. Eleven months after the election, in Darwall’s phrase, “Bill Gates read the funeral rites for climate change”, an epiphanic retreat from doomsday rhetoric.
The Russian blind spot
It is all the more surprising, then, that a writer so alert to the manufactured consensus on climate and Covid accepts the Western consensus on Russia almost wholesale. “Russia today and Germany in the 1920s and 1930s are both revisionist powers,” he writes. “Barack Obama, Angela Merkel and her band of EU appeasers had cleared the way for Europe’s most destructive war since World War II.” He calls the “Washington-backed coup” narrative of 2014, which John Mearsheimer adopted, “spurious”. Yet Mearsheimer’s broader thesis, that NATO expansion lay at the root of the conflict, echoes the warnings of diplomats such as George Kennan and William Burns.
To his credit, Darwall gives the realists a hearing. He quotes William Burns, then US ambassador in Moscow, warning Condoleezza Rice in February 2008 that “Ukrainian entry into NATO is the brightest of all red lines for the Russian elite (not just Putin).” Burns had already cabled that membership could split Ukraine and “force Russia to decide whether to intervene”. He quotes Sir Roderic Lyne, Britain’s former ambassador to Moscow, who called the push to bring Ukraine and Georgia into NATO at Bucharest “stupid on every level”. He even concedes that Western governments “were culpable in ignoring the advice of their diplomats and national security experts”. He names George Kennan, “the architect of Cold War containment”, among the critics but does not quote Kennan’s own 1998 verdict that NATO expansion was “a tragic mistake” and “the beginning of a new cold war”.
Darwall nonetheless dismisses the warnings on three grounds, none of which I find persuasive. First, he cites a 1990 memo by Gorbachev’s adviser Anatoly Chernyaev arguing that Moscow’s security rests on the nuclear balance, so NATO’s advance could not really threaten it. By that logic the United States, with overwhelming nuclear superiority in 1962, had nothing to fear from Soviet missiles in Cuba. It risked nuclear war anyway. Second, he notes that Viktor Yanukovych’s declaration of neutrality in 2010 took NATO membership off the table and that it returned only because of Putin’s aggression. But Yanukovych was driven from office in 2014, and the 2008 Bucharest promise that Ukraine “will become” a member was never withdrawn. Third, he cites Britain’s then Defence Secretary Ben Wallace for the claim that ethnonationalism, not NATO expansion, lies at the heart of Putin’s position. A minister who would soon be sending Ukraine made-in-Britain long-range Storm Shadow cruise missiles is hardly a disinterested witness.
The Norwegian scholar Glenn Diesen put the realist case in a recent interview. The post-Cold War settlement, he argues, was meant to rest on indivisible security, the principle written into the 1990 Charter of Paris that no state should enhance its security at the expense of another’s. Darwall argues that the “not one inch eastward” assurances given to Gorbachev concerned German reunification only and that NATO expansion beyond Germany “was simply not an issue at the time”. Even if that is so, NATO’s march to Russia’s borders replaced indivisible security with the potential for NATO to base nuclear-capable missiles closer to Russia, down to seven to 10 minutes’ flight time to Moscow. In this view a neutral Ukraine was always in everyone’s interest, Ukraine’s above all, as Henry Kissinger argued in 2014.
Darwall’s account contains an unresolved conundrum. Ukraine’s move to the West, he writes, threatened not Russian security but “Putin’s rule”, and he quotes Ambassador Lyne saying the Kremlin’s leaders “know they are not legitimate”. On this telling, Putin is so weak that he cannot afford a free Ukraine moving towards the EU and NATO to be held up as an example for ordinary Russians to emulate. Yet Darwall himself concedes that Ukraine was “poorer, more corrupt, more oligarch-dominated and less politically stable” than Russia, hardly a model Russians were clamouring to follow. A few pages later Putin is Bismarck, a cold calculator bent on redrawing the map of Europe, a revisionist power akin to interwar Germany with “ambitions to re-establish Russian power in the post-Soviet space”. Darwall also cites Angela Stent’s observation that after 1991 Russia’s presence in Europe “had shrunk to its smallest extent since the 17th Century”. A Russia that could not take Kyiv in 2022 is hardly a Wehrmacht poised on the Rhine.
What the appeasement frame leaves out
Darwall sees appeasement in the West’s insistence on the Minsk agreements. He describes Foreign Secretary Philip Hammond urging Kyiv to honour them as “epitomising the prevailing spirit of appeasement”. Yet Merkel herself later admitted that Minsk was “an attempt to give Ukraine time”. The book is silent on the Istanbul talks of spring 2022, which, as Samuel Charap and Sergey Radchenko have documented, came close to a settlement built on Ukrainian neutrality. If there was a failure of Western statecraft, it looks less like appeasement than its opposite.
Darwall notes that Volodymyr Zelensky won 73% of the vote in 2019 by offering “the prospect of peace with Russia through dialogue”, and he concludes that Putin’s subsequent choices “defy reason”. The question not asked is why that mandate was never delivered, and why the Istanbul talks of spring 2022 came so close to a settlement only to collapse after Boris Johnson’s visit to Kyiv. According to Ukrainska Pravda’s sources, Johnson’s message was that Putin “should be pressured, not negotiated with”; Johnson calls the charge that he sank the talks “total nonsense”. By 2024, Zelensky had instead signed a law to ban religious organisations affiliated with the Russian Orthodox Church.
Darwall’s account of the green NGOs in the corridors of power in Western capitals and within the UN and other multilateral agencies is among the most penetrating analyses available in the literature about these amorphous entities. But disappointingly, there is little if any coverage of Washington DC’s ‘democracy promotion’ networks run by the State Department and its grantees and quasi-governmental bodies such as the Congress-funded National Endowment for Democracy.
Darwall notes that Victoria Nuland – the Obama State Department’s point woman on Ukraine – was in Kyiv backing the protesters when she was caught on a leaked call discussing who should form the next government. Darwall casts her – not without reason – as someone who “would acquire an outsize role in the depiction of subsequent events, not least because that’s how she liked to present herself”. In December 2013, three weeks into the Maidan protests, Nuland told a Washington DC audience that since 1991 the United States had “invested over $5 billion” to assist Ukraine’s ‘democratic’ development. Tracking these vast sums through the web of the State Department’s and USAID’s NGO grantees in ‘democracy promotion’ would have been of considerable interest to understanding the events of the Maidan revolution.
At its economic core, Russian-European relations have been based on Soviet and then Russian natural gas, flowing to West Germany since 1973 and a pillar of German industry for half a century. And it was disputes over natural gas trade that created “the first test of wills between the Paper Empire [i.e. the EU] and Vladimir Putin”, as Darwall puts it. Following Thane Gustafson’s account, Darwall casts the EU’s victory over Gazprom on its third energy package as proof that “the Paper Empire had teeth”. An oil and gas industry veteran might see instead gas following oil after the 1986 oil price collapse, from rigid OPEC-based oil-indexed contracts towards liquid spot markets. Darwall charges Gazprom with “softening up” Europe in 2021, while conceding that it “continued to honour its long-term gas contracts”. A supplier that meets its contracts and declines to sell more into a spot market is behaving as the liberalised market Brussels built incentivised it to.
What’s sauce for the goose
Perhaps the deepest omission in many accounts of Russia’s alleged revanchism under President Putin is the Cuban analogy. Darwall’s book offers no mention of the 1962 missile crisis. Glenn Diesen asks us to imagine a Russia helping to topple an elected government in Mexico, installing a hostile regime through ‘democracy promotion’ and arming it to strike the US heartland. No American president would or could accept it. To recognise great powers’ security interests on their borders is not appeasement but the beginning of diplomacy.
Darwall calls the 2014 annexation of Crimea, home to Russia’s Black Sea Fleet and an overwhelmingly Russian-speaking population, “the first forcible redrawing of borders in Europe since 1945”. He relegates Kosovo to a “partial exception”. Yet the Kosovo precedent was created by NATO’s bombing of Yugoslavia in 1999 without UN authorisation. The ‘rules-based order’ Darwall invokes was frayed by Western interventions from Serbia to Iraq and Libya long before 2014.
There is an irony here. Darwall quotes with approval the Trump administration’s 2025 National Security Strategy in rejecting “the disastrous ‘climate change’ and ‘Net Zero’ ideologies”. He urges taking “a hammer” to them. But he balks when the same document calls the outsized influence of larger and stronger nations “a timeless truth of international relations”, dismissing realism as “a species of utilitarianism”. He follows Trump on climate, but not on Russia.
None of this makes Russia an innocent. But Darwall, who exposes better than anyone how elites manufactured an existential climate threat, should recognise the pattern when it recurs. Having wrecked their economies with Net Zero, Europe’s leaders now ask their citizens to prepare for war with Russia. I described that descent from green folly to military mobilisation earlier this month.
Realism or dissolution?
Darwall closes with a warning that if the West does not correct its path, “the age of error” will be followed by “an age of dissolution”. It is an ominous warning. On climate, central banking, ESG and Covid, his prescriptions are compelling: smash the Net Zero ideology, re-carbonise and restore democratic choice over expert diktat across the board. But this counter-revolution cannot stop at the water’s edge. It means taking seriously the perceived security concerns of a neighbouring nuclear-armed superpower, as Kennan, Kissinger and Burns did. On that score Darwall’s otherwise formidable book remains a prisoner of the establishment consensus it demolishes so effectively elsewhere. Whatever one’s view is of the vexed Russia question, Darwall’s tour de force should not be tossed lightly aside – it deserves to be closely read and argued with.

A recent Phys.org article by Paul Arnold (November 2, 2026) covers a study reconstructing the climate of 17th- century Transylvania from historical records, showing it was marked by severe cold and wet extremes during the Little Ice Age.
The study, published in PLOS Climate (DOI: 10.1371/journal.pclm.0000961) and led by Ovidiu Răzvan Gaceu (University of Oradea, Romania) with co-authors including Tudor Caciora, analyzed 937 written accounts from 68 localities.
Sources included chronicles, diaries, town and church records, travelogues, administrative and monastic documents. Researchers categorized explicit weather mentions, indirect indicators (e.g., delayed crop ripening, frozen rivers), and societal impacts (ruined crops, food price spikes). They cross-checked accounts for confirmation by multiple sources and compared them with natural proxies such as cave ice and tree rings to improve reliability.
Key findings
Harsh winters: 55 exceptionally severe winters in the century; 36 of them between 1645 and 1700 (during the Maunder Minimum of very low solar activity). From roughly 1645– 1668, most winters were especially cold. Cold weather dominated seasonal reports (about 73%), though there were occasional mild winters and hot summers.
Precipitation: Excessively wet conditions (heavy rain, floods, snow, hail) far outnumbered droughts, though droughts still occurred (e.g., in the 1630s).
Societal impacts: Climate extremes contributed to poor harvests (many years of failures), high food prices, famines (notably periods like 1601– 1606 and 1648– 1652), and conditions favoring epidemics such as plague (reported in 31 years). These compounded existing stresses from wars and political instability. Specific examples include rivers and lakes freezing solid (e.g., 1645), military campaigns halted by cold and snow, and major floods.
Possible drivers of the regional cooling and wetter conditions include low solar activity, volcanic eruptions, and shifts in atmospheric circulation and wind patterns. The authors note these climatic stresses intensified (but did not solely cause) social crises.
This fits the broader Little Ice Age (roughly 1300– 1850s in Europe), with the late 17th century among its coldest phases, especially winters.
It builds on related work by the same group on 16th- century Transylvanian climate (which showed more heat and drought early on). The reconstruction highlights how historical documents (“society’s archive”) complement natural proxies and illustrate both climate variability and human responses.
______________________________________________
The Maunder Minimum (roughly 1645– 1715) was a prolonged period of extremely low solar activity, during which sunspots were rare (fewer than 50 observed in some multi- decade stretches, versus tens of thousands in comparable modern intervals). It is classified as a “grand minimum” of the solar cycle.
Its cause is internal to the Sun and is not fully understood in detail, but the leading scientific explanation centers on the solar dynamo, the process in the Sun’s convective zone that generates and sustains its large- scale magnetic field.
Key points from solar physics
Solar activity (sunspots, flares, etc.) is driven by the dynamo, which normally produces the ~11- year Schwabe cycle (and the underlying ~22- year magnetic Hale cycle).
Grand minima like the Maunder Minimum occur when the dynamo enters a special, suppressed mode. Stochastic (random) fluctuations in key processes—especially the generation of the poloidal magnetic field and variations in meridional circulation (large-scale plasma flows), can push the dynamo below a critical threshold. This leads to intermittent, greatly reduced magnetic activity.
Observational clues supporting a distinct dynamo state include strong north-south hemispheric asymmetry in the few sunspots that did appear, unusual differential rotation, reduced auroral activity, and evidence from cosmogenic isotopes (such as carbon- 14 in tree rings and beryllium-10). The magnetic cycle appears to have continued at a low level rather than stopping completely.
Dynamo models successfully reproduce grand minima when realistic levels of randomness are included, and historical records show the Sun has spent roughly one- sixth of the Holocene in such states.
No external trigger (e.g., a specific planetary alignment or interstellar influence) is required or supported by evidence; the phenomenon arises from the nonlinear, turbulent nature of the solar magnetic engine.
Relation to climate (for context)
The Maunder Minimum roughly overlapped part of the Little Ice Age, and reduced solar irradiance likely contributed modestly to cooler conditions in some regions (especially winters in the Northern Hemisphere).
However, the primary drivers of the broader Little Ice Age cooling are now considered to be volcanic eruptions, with solar changes playing a secondary role. The Little Ice Age began well before the Maunder Minimum.
In short, the Maunder Minimum was caused by a temporary, self- organized suppression of the Sun’s magnetic dynamo due to internal fluctuations. The precise threshold- crossing mechanism remains an active research topic in solar physics.

Climatic extremes and their social implications in 17th century Transylvania: An historical climate reconstruction
Abstract summary
The study reconstructs climate variability in the Principality of Transylvania during the 17th century (part of the Little Ice Age and the Maunder Minimum of very low solar activity) using written historical sources. It focuses on temperature and precipitation anomalies plus related calamities and their societal effects.
Key results:
55 particularly harsh winters in the century; 36 of them occurred during the Maunder Minimum (1645– 1700).
Numerous episodes of excessive precipitation (especially in winter), with wet conditions far outweighing droughts.
These extremes contributed to poor harvests, famine, high food prices, and the spread of severe epidemics (especially plague), worsening existing social and political stresses.
Findings align with natural proxy data (e.g., cave ice, tree rings). Natural drivers such as reduced solar activity and changes in atmospheric circulation are indicated as likely contributors to the colder, wetter conditions, particularly in Maunder Minimum winters.
Study details
Data: 937 distinct climate- related testimonies from 68 localities, drawn from chronicles, diaries, official and monastic regists, travellers’ accounts, etc.
Methods: Sources coded into categories (direct weather mentions, phenologicaland environmental indicators such as frozen rivers or delayed crops, and socio- economic impacts). Independent dual coding with third- party resolution of discrepancies; cross- validation against natural archives.
Context: Builds on the authors’ earlier work on 16th- century Transylvania (which showed more heat and drought early in that century). The 17th century shows a clear shift toward colder and wetter conditions.
The full open- access paper includes maps of source locations, figures on seasonal anomalies, indices of wet and dry conditions, and discussion of how climate extremes interacted with wars, political instability, and disease in the region.

The road out of my hometown in the southern Indian state of Tamil Nadu runs between rows of wind turbines. For most of my life I treated them as scenery, admiring them as a technical marvel.
Danish engineers helped install the state’s first 110 turbines between 1985 and 1992, and the Muppandal cluster in Kanyakumari district grew into India’s largest onshore wind farm at 1.5 gigawatts.
The road out of my hometown in the southern Indian state of Tamil Nadu runs between rows of wind turbines. For most of my life I treated them as scenery, admiring them as a technical marvel.
In 2017, a friend who ran a factory told me how erratic swings in electricity supply had caused damage and lost orders, wiping out months of profits. He linked the problem to the surging and fading of wind power on the grid. That was a warning. Nine years later, the entire state is experiencing the same grid failures at a far higher cost.
Officials blame a heatwave for the need to buy additional power. Peak demand jumped nearly 30%, driven by El Niño conditions that kept air conditioners and fans running long after the usual summer peak. Central generating stations also cut back on generation to accommodate scheduled maintenance.
But the real culprit is a drop in wind production to about 14% of what contracts had promised. Nobody should be surprised. The wind season in Tamil Nadu ends every year around this time. Solar output drops to zero after sunset, which explains why the shortage is between 6 p.m. and midnight. Hydropower, a weather-bound source that depends on reservoir levels and monsoon inflows, offered no meaningful rescue.
Consider who filled the gap. Every bidder in the emergency tender was a gas-fired generator, some of them in Assam 1,400 miles away. Gas won because it starts and stops on command. The state that spent three decades celebrating wind turbines now pays a premium for the one quality they cannot offer – on-demand dispatchability.
Tamil Nadu is India’s second-largest state economy, with a quarter of its output coming from manufacturing, which requires an affordable, continuous supply of electricity.
This month, in Tiruppur, Tamil Nadu’s fourth-largest city, knitwear factories reported production losses as computerized machines failed under sudden outages and low voltage. They suffered the same damage my friend had described nine years ago. Spinning mills near Madurai were told to switch to diesel generators, whose electricity costs significantly more than the grid’s.
Tamil Nadu’s planners must stop relating to installed wind capacity as if it were a reliable source. A turbine that produces at 14% of its contracted level during peak demand cannot support a power grid for many millions of people. India’s second-largest economy needs an energy supply based on coal, natural gas, and nuclear.

A University of Vermont- led team improved a physics- based snow model to better capture Northeast U.S. winter conditions, including midwinter thaws and runoff, which differ from those in the western U.S.
The October 28, 2026, article by Hannah Fischer (UVM Water Resources Institute) covers a study published in Water Resources Research.
Northeast mountain snowpacks, especially at intermediate elevations, are shaped by a milder, more humid climate. They feature frequent melt- freeze cycles, denser snow, and midwinter thaws, often leading to rain- on- snow events and flooding. Standard snow models, largely developed and tested for western conditions, often fail to represent these dynamics accurately near freezing temperatures.
Researchers from UVM, the U.S. Geological Survey (USGS), and the University of British Columbia applied and refined a physics- based model (drawing on approaches like SnowModel) focused on Mount Mansfield (Vermont’s highest peak) and the adjacent Ranch Brook watershed (a long- term hydrological monitoring site draining to the Winooski River and Lake Champlain).
Elevations ranged from about 200- 1,300 meters.
Key findings include:
The snowpack is highly sensitive to temperature and precipitation changes, especially at middle elevations (700- 900 m). This band often aligns with the rain- snow line and near- freezing conditions; a shift of roughly +1.1°C can flip precipitation from snow to rain and accelerate melt.
The improved model more accurately simulated observed snow water equivalent (SWE), snow depth, snowpack density, and snowmelt- derived runoff compared with prior approaches.
This enables better analysis of how warmer, wetter winters may affect snowpack and hydrology, supporting improved flood forecasting and understanding of vulnerable systems.
Lead author Anna Grunes (UVM M.S. graduate in Civil and Environmental Engineering) noted the work advances understanding of highly vulnerable snowpacks amid rapid winter changes, with Vermont’s Green Mountains serving as a useful natural laboratory.
USGS research hydrologist (emeritus) Jamie Shanley highlighted its value for the region’s tourism- dependent snow season and broader hydrologic insights.
Additional co- authors included UVM faculty (Arne Bomblies, Donna Rizzo, Patrick Clemins, Beverley Wemple) and collaborators from USGS and elsewhere.

Application of a Physics-Based Snow Model to Assess Impacts of a Changing Climate on Snowpack and Snowmelt in the Northeastern United States
It is the study referenced in the University of Vermont press release (“UVM Researchers Explore the Northeast’s Vulnerable Snowpack” by Hannah Fischer, October 28, 2026).
Lead author is Anna Grunes (M.S. graduate, UVM Civil and Environmental Engineering), with co-authors from UVM, the U.S. Geological Survey (USGS), and the University of British Columbia.
The team adapted and evaluated a distributed physics- based snow model (SnowModel) for the Northeast U.S., specifically a domain centered on Mount Mansfield (Vermont’s highest peak) and the Ranch Brook watershed (long-term hydrological monitoring site on the eastern slope that drains to the Winooski River and Lake Champlain). Elevations span roughly 200- 1,300 m.
Northeast snowpacks differ markedly from those in the western U.S.: milder, more humid conditions produce frequent melt– freeze cycles, denser snow, midwinter thaws, and rain- on- snow events.
Standard models often underperform near 0 °C. The improved configuration better reproduces observed snow water equivalent (SWE), snow depth, density, and melt- derived runoff.
Key technical improvements (drawn from the associated thesis and press summary)
Liquid- water percolation and retention: Gravity- dominated percolation schemes reduced model error most effectively.
Calibration and validation used historical snow surveys plus a newer network of monitoring stations.
Snowpack response is highly elevation- dependent. Middle elevations (≈700- 900 m), near the typical rain– snow transition and freezing level, are especially sensitive.
A modest warming of about +1.1 °C can shift precipitation fully from snow to rain and accelerate melt.
Simulated warmer and wetter conditions increase midwinter melt and runoff pulses while producing an earlier, less pronounced spring freshet. In one example midwinter event, +3.3 °C produced a substantial surface- water- input spike (tens of mm) at mid- elevations where baseline melt was minimal.
The work improves representation of midwinter runoff and supports better flood analysis and forecasting under changing winters. It highlights the vulnerability of intermediate- elevation Northeast snowpacks that are critical for water resources, ecosystems, and winter recreation and tourism.

In the temperate, humid mountains of the northeastern United States (U.S.), seasonal snowmelt plays an important role in the annual water balance, and midwinter rain-on-snow events and spring snowmelt are common drivers of flooding. Frequent near-freezing winter temperatures make the region particularly susceptible to midwinter rain and ongoing climate warming. However, models used to evaluate seasonal snowpack evolution and inform snowmelt-derived streamflow forecasting remain limited in their ability to represent these conditions. Here, we evaluate northeastern U.S. snowpack under a changing climate using a distributed, physics-based snowpack model. SnowModel was applied to a domain in the state of Vermont, surrounding Mount Mansfield (1,340 m). Testing various model configurations showed that incorporating a wet-bulb temperature threshold (0.5°C) for precipitation phase partitioning and a gravity-driven liquid water percolation scheme most effectively reduced model error. These modifications reduced mean percent bias by 33 and 75 percentage points for snow depth and snow water equivalent (SWE), respectively. Using the improved model, we assessed the effects of climate-driven changes through a range of perturbations in temperature and precipitation. Middle elevations (700–900 m) were the most sensitive to these changes, exhibiting up to a 60% decrease in peak SWE with modest warming (+1.1°C). Incremental warming caused increased midwinter melt, including an event in which a +3.3°C temperature increase produced 40 mm of additional snowmelt (+700%) in 1 day at mid-elevations. These findings demonstrate the sensitivity of the northeastern U.S. snowpack to climate warming, and
