Explaining climate change science & rebutting global warming misinformation
Global warming is real and human-caused. It is leading to large-scale climate change. Under the guise of climate "skepticism", the public is bombarded with misinformation that casts doubt on the reality of human-caused global warming. This website gets skeptical about global warming "skepticism".
Our mission is simple: debunk climate misinformation by presenting peer-reviewed science and explaining the techniques of science denial, discourses of climate delay, and climate solutions denial.

This is a re-post from The Climate Brink
El Niño and its sister La Niña are the warm and cool phases of a natural climate pattern across the tropical Pacific (collectively called the El Niño-Southern Oscillation, or ENSO). The planet shifts back and forth irregularly between El Niño and La Niña every two to seven years, changing ocean temperatures and disrupting wind and rainfall patterns across the tropics. This in turn has a number of second-order effects around the planet.
El Niño also has a major effect on global temperatures, reducing the rate of ocean heat uptake and increasing atmospheric temperatures. Global mean temperature can temporarily increase as much as 0.2C during a very strong El Niño event, with the maximum temperature increase in global mean temperature occurring around 3 to 4 months after El Niño conditions peak in the tropical Pacific.
In the past week, a number of modeling groups that try to forecast future ENSO conditions have released forecasts that suggest that a very strong El Niño may be in the works for late 2026. This is a notable revision upwards from earlier forecasts in January and February that suggested that an El Niño might develop, but that it would likely be more modest. Historically it has been hard to precisely predict ENSO development early in the year – hence the famed spring predictability barrier –
I’ve collected 11 different models that have been updated since the beginning of March. Each of these in turn features a number of ensemble members, so that we end up with 433 total ENSO forecasts. A subset of these obtained from Copernicus’ C3S (from Australia’s BOM, CMCC, DWD, ECMWF, and Meteo-France) only extend through August, while the remainder (CFSv2, ECC-CanESM5, ECC-GEM5.2, NASA-GEOS, NCAR-CCSM4, and NCAR-CESM1) extend all the way through November.
The figure below shows a combined super plume of all the ensemble members of all the models, with the mean of each model shown as a bold colored line and the average of all the models (the multi-model mean) shown as a black dashed line.

Skeptical Science is partnering with Gigafact to produce fact briefs — bite-sized fact checks of trending claims. You can submit claims you think need checking via the tipline.
Is 'wind-turbine syndrome' a medically recognized diagnosis?
An extensive body of studies and reviews has not found a clear, direct link between wind turbines’ low-frequency sound and any specific health syndromes. No medical organization recognizes such diagnoses.
Wind turbines do produce low-frequency noise, but at typical residential distances it is often below normal hearing levels. Public health agencies and systematic reviews conclude that reported symptoms such as sleep disruption and stress are not consistently tied to low-frequency sound exposure. Instead, research suggests complaints are more strongly associated with factors such as annoyance, worry, and negative expectations about nearby turbines.
An analysis of complaints across 51 Australian wind farms between 1993 and 2012 found that health and noise complaints were uncommon for years, then rose sharply after the term “wind turbine syndrome” was newly coined and popularized in 2009, suggesting self-pathologization.
Overall, the evidence does not support low-frequency turbine noise as a cause of a distinct medical condition.

This is a re-post from Yale Climate Connections
Despite their polar-opposite politics, California and Texas have achieved the same distinction: They’re both national leaders in producing renewable energy.
Wind and solar today account for 40% of power generation in California and 30% in Texas, well above the national average of 17%.
California and Texas alone account for more than one-third of the U.S.’s solar and wind power generation and over half of its battery storage capacity — shares that continue to grow.
The policy approaches used by California and Texas differ dramatically.
“California has used centralized state control to achieve lots of wind, solar, and storage, while Texas has accomplished the same outcomes via open-access and competitive choice,” said Beth Garza, senior fellow with R Street’s energy and environmental policy team and former director of the Electric Reliability Council of Texas Independent Market Monitor, in an email.
Both state governments have invested in power generation, but while California procured clean energy, “Texas created the Texas Energy Fund to provide low-interest loans and cash completion bonuses for new natural gas-fueled generation,” Garza added.
Rather than halt the growth of renewables, the expansion of natural gas in Texas came at the expense of coal. And all of the growth in electricity generation in both states over the past 15 years has been met by solar panels and wind turbines.
Simple dollars and cents continue to propel the expansion of renewable energy in the two states.
“The economics of solar and energy storage as new resources drive them to the top” in California’s state power purchases, said Brendan Pierpont, Director of Electricity at Energy Innovation, in an email. And in Texas’s free market system, “wind, solar, and energy storage are leading the way because they’re winners economically,” there as well, he added.
The biggest difference is that Texas uses a lot more energy, including more total clean energy, despite having a smaller population than efficiency-minded California.

The U.S. Energy Information Administration recently forecast that the U.S. will install a record-shattering amount of new power capacity in 2026, with solar panels and battery storage accounting for nearly 80% of those additions. Texas is expected to install 40% of that new solar capacity and 53% of the batteries, with California accounting for a further 6% and 14% of each, respectively.

The emerging human fingerprint on global extreme fire weather, Turco et al., Science Advances
Extreme fire weather (hot, dry, and windy conditions) has intensified globally, yet formally attributing this trend to anthropogenic climate change remains challenging. Here, we analyze global trends in extreme fire weather days (FWI95d, annual count of days with Fire Weather Index above the 95th percentile) over 1980–2023, using climate model ensembles, observational data, and fingerprint detection techniques. We find that the observed increase in extreme fire weather bears a clear externally forced signal, detectable at 99% confidence above natural variability and attributable to human-induced climate change. This emerging human-induced fingerprint on extreme fire weather highlights a benchmark for climate science and underscores the urgency of integrating these insights into wildfire risk management and adaptation strategies.
An increase in the spatial extent of European floods over the last 70 years, Fang et al., Hydrology and Earth System Sciences
Floods regularly cause substantial damage worldwide. Changing flood characteristics, e.g., due to climate change, pose challenges to flood risk management. The spatial extent of floods is an important indicator of potential impacts, as consequences of widespread floods are particularly difficult to mitigate. The highly uneven station distribution in space and time, however, limits the ability to quantify flood characteristics and, in particular, changes in flood extents over large regions. Here, we use observation-driven routed runoff simulations over the last 70 years in Europe from a state-of-the-art hydrological model (the mesoscale Hydrologic Model – mHM) to identify large spatiotemporally connected flood events. Our identified spatiotemporal flood events compare well against an independent flood impact database. We find that flood extents increase by 11.3 % on average across Europe. This increase occurs over most of Europe, except for parts of eastern and southwestern Europe. Over northern Europe, the increase in flood extent is mainly driven by the overall increase in flood magnitude caused by increasing precipitation and snowmelt. In contrast, the increasing trend in flood extent over central Europe can be attributed to an increase in the spatial extent of heavy precipitation. Overall, our study illustrates the opportunities to combine long-term consistent regional runoff simulations with a spatiotemporal flood detection algorithm to identify large-scale trends in key flood characteristics and their drivers. The detected change in flood extent should be considered in risk assessments as it may challenge flood control and water resource management.
Global record-shattering breadbasket droughts emerge from moderately extreme regional events, Li et al., Nature Communications
Simultaneous droughts across multiple maize-producing regions can strike record-shattering portions of the global maize agricultural area, threatening global food security as the system is poorly adapted to large shocks. Yet the future probability of such global droughts remains unknown. Here, we close this gap by analyzing surface soil moisture data from large ensemble climate models under future emission scenarios. During 2026-2099, the chance of at least one such event is 52% (32–80%, range across models) under an intermediate emission scenario and 60% (32–100%) under high emissions, about seven to eleven times higher than expected if there were no long-term trends in soil moisture. These elevated probabilities are primarily driven by long-term drying in Brazil, Europe, and the USA. Interestingly, global record-shattering droughts do not emerge from simultaneous regional record-shattering events, but they mostly occur when several regions simultaneously face moderately extreme droughts relative to the new climate. These results demonstrate a high potential for an upcoming global record-shattering drought in crop-producing areas, an under-recognized risk for food security.
The future of direct air capture in Canada: A systematic scenario-based exploration of barriers and possibilities, Motlaghzadeh & Schweizer, Energy Research & Social Science
Integrated assessment models often overlook the interdependencies of socio-political factors shaping the deployment direct air capture (DAC), leading to projections that may be overly optimistic. To address this gap, we systematically explore the conditions under which DAC may (or not) emerge as a competitive carbon dioxide removal (CDR) option in Canada using the system-theoretical scenario method cross-impact balances (CIB), which accommodates both qualitative and quantitative scenario factors. Based on the literature, we identified 10 key factors affecting DAC deployment such as interjurisdictional regulations, public perception, and clean electricity availability. Their interrelationships were assessed by 27 experts to develop an expert-informed CIB model that identified 15 internally consistent scenarios. Results reveal inter-related constraints that DAC must overcome to become competitive with other CDR methods. The cost of DAC remains a significant barrier; unless technological breakthroughs or economies of scale push costs down, DAC is unlikely to play a major future role. Even with cost improvements, public perception remains key—strong societal opposition, particularly around CO? transport and storage infrastructure—can delay or block projects. Additionally, interjurisdictional policy coherence matters to advance DAC deployment. From a domestic decision-maker perspective, some of these barriers—such as DAC cost—are influenced largely by global deployment and may be outside their control. However, others—such as policy coherence—can be shaped by domestic policy action. By integrating expert knowledge of qualitative factors using systematic scenario analysis, this study highlights how different institutional and socio-political configurations condition the feasibility of large-scale DAC deployment in Canada.
From committed to dismissive: how conspiracy mentality and trust in the democratic (political) system shape climate policy perspectives in Germany, Lütkes et al., Climate Policy
The implementation of new policy measures to mitigate climate often leads to public backlash, undermining their political feasibility, especially in democracies. To understand public opinion and the various positions within the polarized climate policy debate, our study draws on a representative survey conducted in Germany in 2022. We found strong evidence for four distinct groups, which we label as being ‘committed’ to, ‘worried’ about or ‘indifferent’ to climate policy initiatives, or being outright ‘dismissive’ of such policies. Distrust of democratic institutions, processes, politicians and norms as well as a tendency towards a conspiracy mentality play a crucial role in explaining the cleavage between these groups, particularly between the committed and the dismissive. The committed are a rather West German, female, democracy appreciating, urban and educated social group without a conspiracy mentality. In contrast, the dismissive group exhibits a conspiracy mentality and is sceptical of the political elite. This reflects a West German green and an East German right-wing populist milieu. The worried, who are concerned about losing their jobs, increasing social conflict and falling living standards as a result of climate policy, and the largest group of the indifferent are less well explained by the socio-demographic, attitudinal covariates and require further research. The results of the segmentation can be used to design effective climate communication and develop target group-orientated approaches.
From this week's government/NGO section:
U.S. Billion-Dollar Weather and Climate Disasters in 2025, Adam Smith, Climate Central
Research by Climate Central shows that during 2025, there were 23 individual weather and climate disasters with at least $1 billion in damages. This was the third-highest count of billion-dollar disasters (inflation-adjusted to 2025 dollars) since 1980, trailing only 2023 and 2024, with 28 and 27 events, respectively. The total, direct cost of these 23 events in 2025 was approximately $115.0 billion, with 276 direct and indirect fatalities. The author summarizes the costliest events of 2025 and puts them in the context of historical trends in billion-dollar disasters since 1980. He also explore the influence of our growing exposure, vulnerability, and climate change on the increasing trend of these expensive and deadly disasters.
Toxic Accounts. From Greenwashing to Gaslighting, Nayantara Dutta, Clean Creatives
In a first-of-its-kind research project, the author has decoded the narrative shifts in fossil fuel campaigns between 2020 and 2024, detailing how narrative strategy in oil and gas companies' advertising and public relations campaigns has shifted. The evidence documents how, between 2020 and 2024, oil and gas campaigns shifted from setting climate targets and saying “we’re part of the solution” to emphasizing fossil fuel dependence and convincing people “you can’t live without us.” In parallel, the author saw shareholders follow suit and move from supporting climate action to prioritizing fossil fuel profitability. Oil majors have always been preoccupied with social license, but now, the fossil fuel industry is radicalizing. Companies like BP and Shell, which have a history of greenwashing and made net zero pledges in 2020. Now they are going all in on fossil fuels. They are advertising false solutions like carbon capture and storage, natural gas and biofuels, which increase fossil fuel dependence.

Video description
Jeffrey Epstein was a climate change denier. The Epstein Files have uncovered a number of revelations about how power operates across the globe. And this includes the discussion of climate change - and climate denial - within these exchanges between Jeffrey Epstein and the people he associated with – from scientists to Donald Trump. So what did Jeffrey Epstein have to say when it came to climate change? And what do these files reveal about the links between climate denial and power?

When English author J.R.R. Tolkien crafted his fantasy world Middle-earth, he argued storytellers are essentially “sub-creators” – they build fictional realms with internally consistent laws.
For a world to be truly immersive and believable, readers apply what is known as the “principle of minimal departure”. This assumes anything not explicitly magical, such as a planet’s weather or gravity, must adhere to the laws of the real world.
In this spirit of rigorous worldbuilding, we just published a new study where we merged the disparate disciplines of literary worldbuilding and climate modelling.
We used complex computer programs – the same ones used to forecast Earth’s future warming scenarios – to simulate the climates of famous fantasy settings such as Tolkien’s Middle-earth, the continents of Westeros in the Game of Thrones, and the far-future Earth in The Wheel of Time series. We also built a model for a fictional world developed by one of us.
It’s a seemingly whimsical exercise, but it serves serious purposes.
For starters, it provides new details on fictional worlds beyond what the author shared, “filling the gaps” with science.
More importantly, it offers a new way for us to communicate the fundamental physics of climate science to a broad, general audience. And exploring climate model behaviour under fantastical settings helps our understanding of model physics.
Why the Misty Mountains are so misty
Tolkien, the author of The Lord of the Rings, was known for his extraordinary attention to detail. He meticulously calculated distances, times, and even phenomena such as the direction of the wind at every step along the characters’ journey.
Working from Tolkien’s own detailed maps, we fed Middle-earth’s topography (land height) and bathymetry (ocean depth) into an advanced climate model.
Since Tolkien intended Middle-earth to be our own Earth at a distant point in the past, we assumed its physical parameters – such as the planetary radius, rotation rate, and distance from the Sun – were identical to ours. We then simulated the world’s climate.
The results were a remarkable confirmation of Tolkien’s intuitive worldbuilding.
The model predicted a climate similar to Western Europe and North Africa – unsurprising, given Tolkien’s geographical inspiration.
The highest precipitation fell on and to the west of the Misty Mountains, with a drier “rain-shadow” effect to the east. This effect is caused by prevailing westerly winds forcing moist air to rise and cool over the mountains, condensing water vapour into rain or snow before it reaches the eastern side.
The model’s prediction of extensive forest cover across much of Middle-earth was consistent with Elrond’s claim that in the past, squirrels could travel from the Shire to Dunland without touching the ground.

This is a re-post from The Climate Brink by Andrew Dessler
When people debate the cost of fossil fuels versus renewables, the conversation almost always centers on the price at the pump or the cost per kilowatt-hour on your electricity bill. That’s understandable — those are the costs you can see. But they’re not the whole story.
The rest of the story are subsidies. In most discussions, it’s laser-focused on subsidies for renewable energy, not fossil fuels. But fossil fuels get enormous subsidies. Those are deeply hidden, though, spread across government budgets, healthcare systems, and military spending in ways most people can’t connect back to their energy choices.
To the extent that they do get attention, most of it goes to the implicit subsidy for fossil fuels from climate change and air pollution, which economists have valued at trillions of dollars per year.
But there’s another hidden subsidy that few talk about: national security. And right now, as oil prices surge in response to U.S. strikes on Iran, that cost is impossible to ignore.

Weather Rescue at Sea: Recovering Historical Weather Observations From 19th Century British Naval Ships, Teleti et al., Geoscience Data Journal
Ship logbooks represent a critical source of historical meteorological data, providing valuable observations of barometric pressure, air temperature, sea surface temperature, wind force and direction, and other variables. Substantial quantities of these records are unavailable to climate science as they have not yet been transcribed. We present ‘Weather Rescue at Sea’, a citizen-science project which transcribed millions of weather observations contained in 19th Century UK Royal Navy ship logbooks. We describe the logbook structure and weather observation-taking instructions and discuss significant challenges with the translation of handwritten text into accurate data due to errors arising from ambiguous handwriting, historical terminology, and inconsistent metadata. We present the dataset and explore its spatio-temporal characteristics. The corrected and quality-assured datasets will enhance climate reanalyses and other historical reconstructions of the pre- and early industrial climate by providing more input meteorological data. Furthermore, we highlight emerging tools, such as AI-driven transcription correction, and outline remaining challenges in fully leveraging these historical records to advance climate science.
Climate-Driven Changes in Wildfire Seasonality Across North America, Fan et al., Geophysical Research Letters
Climate change alters the frequency and intensity of wildfires, but its impact on the seasonal patterns of wildfires remains underexplored. Here, we quantify historical changes in wildfire seasonality across different ecoregions in North America and assess how climate change may affect these seasonal patterns. Our study finds that boreal and taiga forests have experienced a clear advance in seasonal wildfire activity, whereas Mediterranean and desert regions show delayed and extended late-season burning. Prairie and humid forest regions exhibit comparatively muted change. Attribution analysis shows that atmospheric dryness is the dominant control, while antecedent temperature, precipitation, and soil moisture indirectly shape wildfire risk through vegetation and fuel continuity at different lag times. These findings provide a basis for interpreting future region-specific changes in wildfire seasonality and emphasize the need for region-specific assessments of future wildfire activity.
Rates of Sea-Level Rise Are Highly Sensitive to Ice Viscosity Parameters in Model Benchmarks, Martin et al., AGU Advances
Glacier flow plays a major role in current and future rates of globally averaged sea-level rise. The viscosity of glacial ice, controlling the rate of flow, decreases as stress increases and is highly sensitive to the value of the stress exponent, n, in the constitutive equation for viscous flow. Glaciologists and climate modelers almost exclusively assume n=3 when modeling ice flow and projecting sea-level rise through forward modeling. However, recent work suggests that n~4 better fits observations, prompting the question: How sensitive are projections of sea-level rise to the value of n? We use an established community ice flow model and standard benchmark experiments designed as an idealized representation of Pine Island Glacier, West Antarctica. While initializing an n=3 model to match observations of an n=4 ice sheet is possible, we find that incorrectly assuming n=3 when in fact n=4 dramatically underestimates rates of sea-level rise. The scale of this error grows nonlinearly with the magnitude of the climate forcing, acting to increase projection uncertainties. Additionally, we find that models often account for this stress-dependent rheology mismatch during model initialization in a way that masks this rheological effect in the short term while leaving model outputs vulnerable to larger biases in longer-term projections. Initializations to observations of Pine Island Glacier display similar rheology-mismatch fingerprints to our idealized example.
Beyond denial: climate delay discourses and public opinion on government climate action in the United States, Kulin & Rhodes, Environmental Politics
Discourses of climate delay increasingly permeate debates on climate action, yet studies examining the prevalence of public beliefs aligning with climate delay discourses – and their potential consequences for attitudes toward government climate action – are currently lacking. Past research has identified twelve discourses that acknowledge the existence of climate change yet justify inaction or inadequate responses. We design 48 survey items to measure the prevalence of beliefs consistent with these discourses via a representative web-based survey in the United States (n = 1,580). We then analyze the statistical relationship between these beliefs and public demand for government climate action as well as support for climate policies. Our results show that while beliefs consistent with most climate delay discourses are widespread in the U.S. some are more closely related to policy preferences. Our findings may therefore guide targeted counter-narratives to more effectively increase public demand and support for urgent climate policymaking.
ClimarisQ: What can we learn from playing a game for climate education?, Faranda et al., Geoscience Communication
ClimarisQ is both a web and mobile game developed by the Institut Pierre-Simon Laplace to support climate change communication through interactive decision-making. This paper presents an exploratory evaluation of the game based on a post-play questionnaire completed by 77 users. Respondents rated ClimarisQ positively in terms of usability and scientific credibility. Self-reported outcomes indicate that the game supported reflection on the complexity, trade-offs, and uncertainty of climate-related decision-making, rather than the acquisition of factual knowledge, particularly among users with prior expertise. The respondent group was predominantly composed of educated and climate-aware adults, which limits generalization to other audiences. Beyond the questionnaire, the game has been tested in dozens of facilitated sessions with thousands of non-specialist participants, with consistently positive feedback. These results suggest that ClimarisQ can function as a complementary tool for climate education and outreach, especially when used in facilitated settings that encourage discussion and interpretation.

The Urgent Case Against Data Centers, Food and Water Watch
Data centers and artificial intelligence (AI) are driving higher energy bills, more climate chaos, dwindling water supplies, and much more. Based on the latest research, there are 10 ways data centers leech off communities and the planet for Big Tech’s profit including a single hyperscale data center can consume as much energy as 2 million U.S. households; the thirst for fuel is being met by keeping old coal-fired power plants running and by building new natural gas ones; increased energy demand can raise residential rates, which soared 31 percent from 2020 to 2025 (compared to 4 percent from 2015 to 2020); and by 2028, AI data centers could use as much water as 18.5 million households, just for cooling their servers.
Bubble or Nothing, Advait Arun, Center for Public Enterprise
Should economic conditions in the tech sector sour, the burgeoning artificial intelligence (AI) boom may evaporate—and, with it, the economic activity associated with the boom in data center development. Data centers are an asset with the characteristics of both real estate and infrastructure: Data centers have tenants, chiefly large tech companies, that are undertaking expensive long-term capital investment plays with fast-depreciating assets and minimal cash flow to show for them. A careful review of these characteristics suggest that the sector faces the following salient risks including data center tenants will undertake multiple cycles of intense and increasingly expensive capital expenditure within a single lease term, posing considerable tenant churn risks to data center developers. This asset-liability mismatch between data center developers and their tenants will strain developers’ creditworthiness without guarantees from market-leading tech companies. Circular financing, or “roundabouting,” among so-called hyperscaler tenants—the leading tech companies and AI service providers—create an interlocking liability structure across the sector. These tenants comprise an incredibly large share of the market and are financing each others’ expansion, creating concentration risks for lenders and shareholders.

This is a re-post from Yale Climate Connections by Sarella Arkkila
Mixing science and creativity, “Human Nature: Nine Ways to Feel about Our Changing Planet” documents our irrefutable impacts on Earth’s climate system and the dire consequences we now face. But it does so much more than that.
Written by Earth scientist Kate Marvel, “Human Nature” starts from the premise that it’s OK for a scientist who has been trained to be objective to have feelings.
“And believe me,” she writes, “I have feelings.”
If the title is a nod to human impacts on the natural world, it’s also a provocation. Marvel doesn’t believe in human nature, “at least not in the sense of immutable characteristics that make a particular outcome inevitable.”
In other words, because human behaviors aren’t set in stone, the future isn’t set in stone, meaning it’s up to us to shape the future that we want. And that future, while hotter and more dangerous, can be marked by solar panels, green cities, and restored forests.
To organize and make sense of her feelings, and to imagine that different and better future, Marvel opens the door to the often opaque and complex world of climate science through mythology, history, and storytelling. Each chapter approaches climate change through a single emotion, from wonder, anger, and guilt, to pride, hope, and love, through fear, grief, and surprise.
Take hope, for example. “Is there any?” Marvel asks.
The short answer is yes.

Can shadow flicker from wind turbines trigger seizures in people with epilepsy?
The flicker of a wind turbine shadow is far below the minimum frequency required to trigger photosensitive epilepsy.
A wind turbine is said to produce a “shadow flicker” when its rotating blades pass between the sun and an observer, creating a repeating pattern of light and shadow.
Photosensitive epilepsy is triggered at frequencies of 3 Hz or higher, or 3 flashes of light per second. Wind turbines generate flicker frequencies of 0.5 to 1 Hz, well below the known minimum trigger frequency.
One study calculated that a typical three-blade turbine would need to operate at 60 rotations per minute (rpm) to potentially trigger photosensitive epilepsy. Modern turbines operate at maximum speeds of only 15 to 17 rpm.
Research and public health surveys have not established a phenomenon of wind turbine-induced photosensitive seizures.

This is a re-post from Resilience by Nate Hagens
Humans aren’t rational. We don’t evaluate facts objectively; instead, we interpret them through our biases, experiences, and backgrounds. What’s more, we’re psychologically motivated to reject or distort information that threatens our identity or worldview – even if it’s scientifically valid. Add to that our modern media landscape where everyone has a different source of “truth” for world events, our ability to understand what is actually true is weaker than ever. How, then, can we combat misinformation when simply presenting the facts is no longer enough – and may even backfire?
In this episode, Nate is joined by John Cook, a researcher who has spent nearly two decades studying science communication and the psychology of misinformation. John shares his journey from creating the education website Skeptical Science in 2007 to his shocking discovery that his well-intentioned debunking efforts might have been counterproductive. He also discusses the “FLICC” framework – a set of five techniques (Fake experts, Logical fallacies, Impossible expectations, Cherry picking, and Conspiracy theories) that cut across all forms of misinformation, from the denial of global heating to vaccine hesitancy, and more. Additionally, John’s research reveals a counterintuitive truth: our tribal identities matter more than our political beliefs in determining what science we accept – yet our aversion to being tricked is bipartisan.
When it comes to reaching a shared understanding of the world, why does every conversation matter – regardless of whether it ends in agreement? When attacks on science have shifted from denying findings to attacking solutions and scientists themselves, are we fighting yesterday’s battle with outdated communication strategies? And while we can’t eliminate motivated reasoning (to which we’re all susceptible), how can we work around it by teaching people to recognize how they’re being misled, rather than just telling them what to believe?
About John Cook
John Cook is a Senior Research Fellow at the Melbourne Centre for Behaviour Change at the University of Melbourne. He is also affiliated with the Center for Climate Change Communication as adjunct faculty. In 2007, he founded Skeptical Science, a website which won the 2011 Australian Museum Eureka Prize for the Advancement of Climate Change Knowledge and 2016 Friend of the Planet Award from the National Center for Science Education. John also created the game Cranky Uncle, combining critical thinking, cartoons, and gamification to build resilience against misinformation, and has worked with organizations such as Facebook, NASA, and UNICEF to develop evidence-based responses to misinformation.
John co-authored the college textbooks Climate Change: Examining the Facts with Weber State University professor Daniel Bedford. He was also a coauthor of the textbook Climate Change Science: A Modern Synthesis and the book Climate Change Denial: Heads in the Sand. Additionally, in 2013, he published a paper analyzing the scientific consensus on climate change that has been highlighted by President Obama and UK Prime Minister David Cameron. He also developed a Massive Open Online Course in 2015 at the University of Queensland on climate science denial, that has received over 40,000 enrollments.

Abrupt Gulf Stream path changes are a precursor to a collapse of the Atlantic Meridional Overturning Circulation, van Westen & Dijkstra, Communications Earth & Environment
The Gulf Stream is part of the Atlantic Meridional Overturning Circulation (AMOC). The AMOC is a tipping element and may collapse under changing forcing. However, the role of the Gulf Stream in such a tipping event is unknown. Here, we investigate the link between the AMOC and Gulf Stream using a high-resolution (0. 1°) stand-alone ocean simulation, in which the AMOC collapses under a slowly-increasing freshwater forcing. AMOC weakening gradually shifts the Gulf Stream near Cape Hatteras northward, followed by an abrupt northward displacement of 219 km within 2 years. This rapid shift occurs a few decades before the simulated AMOC collapse. Satellite altimetry shows a significant (1993–2024, p < 0.05) northward Gulf Stream trend near Cape Hatteras, which is also confirmed in subsurface temperature observations (1965–2024, p < 0.01). These findings provide indirect evidence for present-day AMOC weakening and demonstrate that abrupt Gulf Stream shifts can serve as early warning indicator for AMOC tipping.
High-Resolution Projections of Extreme Heat and Thermal Stress in Southeastern U.S., Lu et al., Weather and Climate Extremes
Considering the increasing frequency, severity, and societal impacts of extreme heat under climate change, understanding the regional dynamics of extreme heat is critical for informing public health preparedness and energy system planning. This study investigates the spatial characteristics, dominant drivers, and future evolution of extreme heat days in North Carolina (NC) and Virginia (VA) using high-resolution simulations from the Weather Research and Forecasting (WRF) model based on the Pseudo Global Warming (PGW) method. The analysis of May to September in the two base years, 2010 and 2011, reveals different heat mechanisms. Extreme heats in 2010 are primarily associated with weak synoptic anomalies, whereas the extreme heats in 2011 exhibit stronger land–atmosphere coupling, characterized by soil moisture depletion. Based on these two distinct types of heat mechanisms, projections comparing the current climate (2000-2020) with the late-century period (2060-2089) under three Shared Socioeconomic Pathways (SSP1-2.6, SSP2-4.5, SSP5-8.5) indicate different increases in daily 2-m maximum temperature ranging from 1.6 °C to over 4.4 °C. These temperature changes are driven by variations in radiative forcing, atmospheric circulation, and land surface conditions. The frequency, duration, and severity of extreme heat days exhibit a nonlinear escalation under the three scenarios. “Danger” and “Extreme Danger” heat days are projected to emerge under SSP5-8.5, underscoring the urgent need for aggressive mitigation and tailored adaptation strategies to reduce thermal stress risks in this region.
Reports from western U.S. firefighters that nighttime fire activity has been increasing during the spans of many of their careers have recently been confirmed by satellite measurements over the 2003–20 period. The hypothesis that increasing nighttime fire activity has been caused by increased nighttime vapor pressure deficit (VPD) is consistent with recent documentation of positive, 40-yr trends in nighttime VPD over the western United States. However, other meteorological conditions such as near-surface wind speed and planetary boundary layer depth also impact fire behavior and exhibit strong diurnal changes that should be expected to help quell nighttime fire activity. This study investigates the extent to which each of these factors has been changing over recent decades and, thereby, may have contributed to the perceived changes in nighttime fire activity. Results quantify the extent to which the summer nighttime distributions of equilibrium dead woody fuel moisture content, planetary boundary layer height, and near-surface wind speed have changed over the western United States based on hourly ERA5 data, considering changes between the most recent decade and the 1980s and 1990s, when many present firefighters began their careers. Changes in the likelihood of experiencing nighttime meteorological conditions in the recent period that would have registered as unusually conducive to fire previously are evaluated considering each variable on its own and in conjunction (simultaneously) with one another. The main objective of this work is to inform further study of the reasons for the observed increases in nighttime fire activity.
Minimizing climate risks will require accelerating the energy transition on all levels and in all sectors. Replacing 1.4 billion fossil with electric road vehicles will, however, be a process spanning multiple decades. Expanding electric bus transit has the potential to reduce the demand for electric cars while needing little additional infrastructure. Yet, accelerating the electrification of public mobility is a challenge in itself. This paper explores the system-wide effect of applying the emerging strategy of e-retrofitting to Europe’s bus fleet. Diesel buses are thereby retrofitted with electric drive-trains, which reduces environmental impacts compared to the production of a new battery-electric bus. This strategy allows to accelerate bus fleet electrification by 15 years and to increase annual transport services by a maximum of 25%, all without the need to prematurely retire functioning buses. Applied across Europe, e-retrofitting buses can save greenhouse gas emissions up to 300 million tons CO, generate jobs, offer business opportunities, reduce raw material demand, and requires minimal additional infrastructure.
ClimarisQ is both a web and mobile game developed by the Institut Pierre-Simon Laplace to support climate change communication through interactive decision-making. This paper presents an exploratory evaluation of the game based on a post-play questionnaire completed by 77 users. Respondents rated ClimarisQ positively in terms of usability and scientific credibility. Self-reported outcomes indicate that the game supported reflection on the complexity, trade-offs, and uncertainty of climate-related decision-making, rather than the acquisition of factual knowledge, particularly among users with prior expertise. The respondent group was predominantly composed of educated and climate-aware adults, which limits generalization to other audiences. Beyond the questionnaire, the game has been tested in dozens of facilitated sessions with thousands of non-specialist participants, with consistently positive feedback. These results suggest that ClimarisQ can function as a complementary tool for climate education and outreach, especially when used in facilitated settings that encourage discussion and interpretation.
The phasing-out of coal-fired power generation is a critical policy imperative in the energy system transition towards climate change mitigation. This research examines whether the public is willing to share the costs that will arise from the phasing-out of coal-fired power generation. To this end, this study analyzes the public's willingness to pay for policies aimed at reducing coal-fired power generation and assesses their economic feasibility. Stated preference data from 1000 Korean households nationwide are analyzed using the contingent valuation method and cost-benefit analysis (CBA). The results indicate that households are willing to pay an average of KRW 4514 (USD 3.45) with a 95% confidence interval of [KRW 4,087, KRW 5017] per month in additional electricity fees for the next five years to implement compensation and support measures for the phasing-out of coal-fired power plants. The results of the CBA, including sensitivity analysis, suggest that the implementation of support and compensation policies for coal power phasing-out may not be economically feasible. The Korean public is not yet fully prepared to bear the costs associated with the phase-out of coal-fired power generation, and either increased electricity tariffs or excessive government investment for this process could provoke considerable controversy.
From this week's government/NGO section:
Takeaways from USA TODAY’s investigation of clean-energy opposition, Bhat et al., USA Today
America’s renewable energy buildout is facing resistance, not just in Washington but in county commission meetings across the country. A growing number of local governments are restricting or outright blocking large-scale wind and solar projects. These restrictions come in the shape of bans, permitting requirements that make projects economically unfeasible or moratoriums that may or may not eventually expire. All the while, changing economics and improved technology have made wind and solar cheaper than natural gas and far cheaper than coal.?The investigation identified at least 755 counties with regulatory mechanisms that render it difficult or impossible to develop large-scale wind or solar projects. The investigation relied on data collected for 3,142 counties covering all 50 states through official announcements, county board meetings, news reports, emails and phone calls to public offices.
Oil spill. How fossil fuel interests are seeping into the voluntary carbon market rulebook, nigo Wyburd and Jonathan Crook, Carbon Market Watch
Despite belonging to the highly polluting fossil fuel sector, major oil and gas companies are not only among the largest buyers of carbon credits, they are also heavily invested in seeking to shape the voluntary carbon market. The authors zoom in this outsized role. They focus on how oil supermajors employ greenwashing strategies, including offsetting their emissions and using carbon credits to give the illusion of meaningful progress towards reaching their climate targets. Driven by a desire to safeguard the supply of cheap and low-quality carbon credits, some fossil fuel companies have also been engaging with policy and governance processes through both formal and informal channels. These fossil fuel interests consistently back approaches that promote carbon credit use that is in alignment with their commercial interests, including expanding the supply of different carbon credit types and continued market growth. In parallel, these companies operate in close proximity to the institutions tasked with defining and safeguarding carbon market integrity, such as the Integrity Council for the Voluntary Carbon Market (ICVCM) and the Voluntary Carbon Market Integrity initiative (VCMI). While insufficient information is publicly available to assess whether the outcomes of the work undertaken by voluntary initiatives has been directly influenced by oil and gas companies and other market actors, there are sufficient grounds to consider this a credible risk that warrants serious scrutiny.

This is a re-post from Yale Climate Connections by Jeff Masters
In brief
- The strongest hurricanes are likely to grow stronger as a result of climate change.
- So far, there has been no significant increase or decrease in the number of major hurricanes making landfall in the United States.
- However, it’s likely that there has been an increase in the number of major hurricanes in the Atlantic as a whole since 1946.
- Also, the intensity of landfalling continental U.S. hurricanes has increased, so even if the total number of landfalls has not increased, their potential to do damage has.
- When major hurricanes do hit, they will do more damage than they did in the past: They will be stronger, wetter, and bring higher storm tides because of sea level rise.
- Expect to see more periods of major U.S. landfall activity in the future, but also gaps when no major landfalls occur.
When I wrote my first-ever blog post on a named storm in the Atlantic on June 9, 2005 — for Tropical Storm Arlene — little did I expect the season of atmospheric mayhem that awaited.
An incredible 28 named storms, 15 hurricanes, and seven major hurricanes later — including four Cat 5s and four U.S. landfalls by major hurricanes — New Year’s Eve 2005 found me blogging on Tropical Storm Zeta a half hour before midnight. I wondered, not for the first time, if climate change had caused us to cross a threshold into a new realm of permanent atmospheric frenzy, since the 2004 hurricane season had also been bonkers.
I asked myself, “Is this going to happen for every Atlantic hurricane season from now on? If so, I’d better get off the computer and go drink some champagne!” And I did.
Fortunately, the 2006 Atlantic hurricane season was an incredible relief — below average in all metrics, with no landfalling hurricanes anywhere in the Atlantic. And remarkably, for the next 11 years, no major hurricanes hit the U.S. — the longest such gap on record (Fig. 1). Perhaps more unbelievable: No hurricanes of any kind hit Florida from 2006-2015 — a 10-year landfall drought.

Video description
Why does the global energy transition look so slow in the headline statistics — even as solar, wind, EVs and heat pumps surge ahead? New analysis from EMBER argues the problem isn’t the transition — it’s the way we’ve been counting it. By shifting the focus from “primary energy” to “useful energy” the paper reveals how electrification dramatically reduces wasted energy and why renewables are far more competitive than traditional charts suggest.

This is a re-post from The Climate Brink
I was reminded of Arthur C. Clark’s famous third law the other day, that “any sufficiently advanced technology is indistinguishable from magic.” I’d recently gotten Claude Code set up on my computer, and was using it to help write the code for some reduced-complexity climate model runs. Suddenly projects that would have taken hours or even days were running in minutes. It was not perfect – I needed to carefully help it create project plans, develop tests, and review the results – but it represented a remarkable step up from the capabilities I was familiar with in past web-based LLM interfaces.
I’m something of an unusual climate scientist as, rather than working in academia, my main role is as the climate research lead at Stripe, a financial technology company in Silicon Valley. As such, I’ve probably used AI far more than most other folks in the scientific community, given that we are strongly encouraged to use it extensively for work. I’ve also worked directly with AI labs on projects to evaluate the performance of LLMs in answering climate science questions, and to help enable AI tools to support scientific collaboration.
I started using GPT3.5 back in 2022 when it first came out. Initially it was a novelty but not particularly useful for scientific applications. It was quite prone to hallucinations, would get into endless spirals of errors it would then try and fix, and would often grossly misinterpret instructions. But it had decent skill at coding, and could (sometimes) help solve bugs in my code much faster than trying to search Stack Overflow or old Reddit posts.
This changed with the release of GPT4 in 2023, and particularly with the release of Code Interpreter that could automate data analysis and visualization capabilities. It still hallucinated, was not great at writing, but could arguably code better than the typical scientist. One of the earlier projects I did was to ask it to help visualize how unusual the summer of 2023 was in terms of global temperatures, which helped generate both the ideas of and code for this somewhat viral Climate Brink post (which I referred to as “gobsmackingly bananas” at the time).
Today the tools are much better than they were in 2023. Hallucinations still exist, but they are much less frequent. As someone who has used these tools more than most in the scientific community, I have a good sense of what they work for and what they do not do well today. The tools I primarily use now are Claude Code (Opus 4.6, via my terminal) and the web-app for Gemini (3.1) for projects where integration with my email, Drive, and other parts of the Google ecosystem is helpful.

Relative Vulnerability of US National Parks to Cumulative and Transformational Climate Impacts, Michalak et al., Conservation Letters
National Parks are under threat from multiple interacting climatic changes, which have already triggered transformations in these protected landscapes. We conducted a multidimensional analysis of climate-change vulnerability for National Parks to identify which parks are most at risk of climate-change impacts and therefore in the greatest need of targeted climate-change vulnerability assessment and planning. We identified 174 (67%) parks as most exposed to one or more potentially transformative climate impacts including fire, drought, sea-level rise, and forest pests and diseases. Cumulative vulnerability across multiple dimensions was the highest for parks in the Midwest and eastern United States due to high physical exposures, the exacerbation of existing stressors, and high surrounding land-use intensity. Western parks exhibited lower cumulative vulnerability due to less intense land use and topography that may provide climatic refugia. However, western parks tended to be most exposed to multiple transformative impacts. These widespread, diverse threats highlight not only the need for coordinated evaluation of vulnerabilities from multiple perspectives, but also the need for park managers to evaluate and plan for potentially irreversible ecological changes to the landscapes and resources that parks are intended to preserve.
[At time of publication the US executive branch has acted to censor access to previously available information about climate change for park visitors.]
Increasing synchronicity of global extreme fire weather, Yin et al., Science Advances
Concurrent extreme fire weather creates favorable conditions for widespread large fires, which can complicate the coordination of fire suppression resources and degrade regional air quality. Here, we examine the patterns and trends of intra- and interregional synchronous fire weather (SFW) and explore their links to climate variability and air quality impacts. We find climatologically elevated intraregional SFW in boreal regions, as well as interregional synchronicity among northern temperate and boreal regions. Significant increases in SFW occurred during 1979 to 2024, with more than a twofold increase observed in most regions. We estimate that over half of the observed increase is attributable to anthropogenic climate change. Internal modes of climate variability strongly influence SFW in several regions, including Equatorial Asia, which experiences 43 additional intraregional SFW days during El Niño years. Furthermore, SFW is strongly correlated with regional fire-sourced PM2.5 in multiple regions globally. These findings highlight the growing challenges posed by SFW for firefighting coordination and human health.
Coastlines retreat tipping point under storm climate changes, Aparicio et al., Scientific Reports
Projected changes in ocean–atmosphere coupling under global warming suggest an intensification of storm climates, which, combined with sea-level rise, poses profound challenges to the resilience of sandy shorelines. Therefore, the definition of relevant indicators assessing beach response regimes to wave climate is crucial for future forecasts Here, we analyze 23 years of satellite-derived shoreline positions together with offshore wave data to quantify storm-induced erosion and post-storm recovery tendencies at synoptic scales. Our approach integrates statistically robust storm composites, compared against in situ observations from six sites worldwide, and demonstrates that daily storm-induced shoreline dynamics can be inferred from monthly global shoreline datasets. By extending the analysis using 60-year of wave reanalysis, we identify a critical threshold beyond which shoreline evolution shifts from a seasonal to a storm-dominated regime, leading to persistent erosion trajectories. Since the late 1950s, the proportion of storm-dominated beaches has increased by 2% globally, with pronounced hot-spots emerging. While local beach morphology remain essential to fully resolve coastal dynamics, our findings reveal coherent large-scale tendencies that complement site-specific surveys and provide a global framework to guide targeted field efforts. These results highlight the pivotal role of storm regime shifts in shaping the future evolution of sandy shorelines.
Deliberate destabilization on trial: Fair-process lessons from the Czech Coal Commission, ?ernoch et al., Energy Research & Social Science
Expert commissions have become pivotal in coal-phase-out governance, yet their capacity to unsettle incumbent coal regimes remains contested: do they genuinely shift entrenched power relations or merely create an illusion of participatory legitimacy? Drawing on energy-justice and transition studies, this article approaches the issue from the perspective of procedural justice and assumes this tenet of justice is crucial in shaping the outcome of an institutionally induced destabilization. We develop a four-part framework of procedural justice – member selection, stakeholder balance, deliberative conditions, and public transparency – and apply this framework to the Czech Coal Commission (2019–2021), which was established as an expert body tasked with establishing the coal phase-out schedule. Our results show that the Czech Coal Commission was blatantly procedurally unjust. Discretionary appointments, industry-leaning membership, and compressed timelines that circumscribed substantive deliberation ultimately enabled coal incumbents to retain power over the outcome. This case underscores that rigorous procedural design is a necessary precondition for commissions to function as effective agents of destabilization within fossil-fuel regimes, and that design choices must be addressed if similar bodies are to support credible and socially legitimate coal exits.

Nearly half of Americans think they'll see catastrophic impacts of climate change in their lifetimes, Alexander Rossell Hayes, Economist/YouGov
A majority (59%) of Americans believe that the world's climate is changing as a result of human activity. A further 22% say the climate is changing but not because of human activity. Only 6% say the climate is not changing Nearly half (45%) of Americans think they will see catastrophic impacts of climate change in their lifetimes. About one-third (31%) do not think they will see catastrophic effects, with the remaining 24% not sure A majority (57%) of Americans say the U.S. should do more to address climate change. Only 16% say that the U.S. should do less Most Democrats (90%) and a majority (58%) of Independents say the U.S. should do more to address climate change. Republicans are more divided: 25% say the U.S. should do more, 29% say it should not change what it's doing, and 33% say it should do less Younger adults are more likely than older Americans to say the U.S. should do more to address climate change.
Global Warming’s Six Americas, Fall 2025, Leiserowitz et al., Yale University and George Mason University
In 2009, the authors identified Global Warming’s Six Americas – the Alarmed, Concerned, Cautious, Disengaged, Doubtful, and Dismissive – six distinct audiences within the American public. The Fall 2025 Climate Change in the American Mind survey finds that 25% of Americans are Alarmed and that the Alarmed outnumber the Dismissive (11%) by a ratio of more than 2 to 1. Further, when the Alarmed and Concerned are grouped together, about half of Americans (52%) fall into one of these audiences. Overall, Americans are more than twice as likely to be Alarmed or Concerned than they are Doubtful or Dismissive (24%).
