'Attack on Independent Science': Trump EPA Removes All Mention of Human-Caused Climate Crisis From Public Webpages
Climate scientist Daniel Swain called it "a deliberate effort to misinform."
Dec 09, 2025
The Trump administration has removed all references to human-caused climate change from Environmental Protection Agency webpages, as well as large amounts of data showing the dramatic warming of the climate over recent decades and the resulting risks.
According to a Tuesday report from the Washington Post, one page on the "Causes of Climate Change" stated as recently as October that "it is unequivocal that human influence has warmed the atmosphere, ocean, and land," a statement that reflects the overwhelming consensus in peer-reviewed literature on climate.
That statement is now nowhere to be found, with those that remain only mentioning "natural" causes of planetary warming like volcanic activity and variations in solar activity.
"The new, near-exclusive emphasis on natural causes of climate change on the EPA's website is now completely out of sync with all available evidence demonstrating overwhelming human influence on contemporary warming trends," explained Daniel Swain, a climate scientist at the University of California Agriculture and Natural Resources, who posted about the changes on social media.
The Intergovernmental Panel on Climate Change (IPCC), which examines tens of thousands of studies from around the globe, found that virtually all warming since the dawn of the industrial era can be attributed to human carbon emissions.
This can be confirmed using the Wayback Machine's last snapshot (from Oct 8, 2025). At some point between Oct 8 & Dec 8, major changes were made to this and other EPA climate change content. Information has either been removed completely or "adjusted" to emphasize natural causes.

Pages about the catastrophic results of climate change have also been scrubbed: One of them allowed users to view several climate change indicators, like the historic decline of Arctic sea ice and glaciers and the increased rates of coastal flooding due to rising sea levels. That page has been deleted entirely.
Another page, which answered frequently asked questions about climate change, now no longer includes questions like, "Is there scientific consensus that human activities are causing today’s climate change?” "How can people reduce the risks of climate change?" and "Who is most at risk from the impacts of climate change?" The page provides no indication that climate change is a human-caused phenomenon, instead only discussing natural factors.
That page links to another that has since been deleted. It once provided extensive information about the risks climate change poses to human health, "from increasing the risk of extreme heat events and heavy storms to increasing the risk of asthma attacks and changing the spread of certain diseases carried by ticks and mosquitoes." Another deleted page discussed the impacts of climate change on children's health and low-income populations.
“This is, I think, one of the more dramatic scrubbings we’ve seen so far in the climate space,” said Swain. "This website is now completely incorrect regarding the changes in climate that we’re seeing today and their causes... It’s clearly a deliberate effort to misinform.”
During his 2024 campaign for reelection, President Donald Trump and his affiliated super political action committees received more than $96 million in direct contributions from oil and gas industry donors, according to a January report from Climate Power. Since retaking office, he has moved to dramatically expand the extraction and use of planet-heating fossil fuels while eliminating investment in clean energy and electric vehicles.
Rachel Cleetus, senior policy director for the Climate and Energy Program at the Union of Concerned Scientists, said, "Deleting and distorting this scientific information only serves to give a free pass to fossil fuel polluters who are raking in profits even as communities reel from extreme heatwaves, record-breaking floods, intensified storms, and catastrophic wildfires."
Cleetus said that the purging of climate information from EPA sites was a prelude to "the likely overturning of the endangerment finding, a legal and scientific foundation for standards to limit the heat-trapping emissions driving climate change and threatening human health."
In July, EPA Administrator Lee Zeldin unveiled a proposal to rescind the 2009 finding, which determined that climate change endangers human life and serves as the legal basis for greenhouse gas regulations under the Clean Air Act.
Undermining climate science is core to that effort, which Andrew Dessler, a climate scientist at Texas A&M, said at the time, "could unravel virtually every US climate regulation on the books, from car emissions standards to power plant rules.”
Shortly after Zeldin announced the rule change, the Department of Energy cobbled together a “Climate Working Group” comprising five authors handpicked by Secretary Chris Wright to produce a climate report that disputes the IPCC's findings and the scientific consensus on climate change.
The report did not undergo peer review and omitted around 99% of the scientific literature the IPCC relied on for its comprehensive findings. A group of climate scientists that independently reviewed the paper found that it “exhibits pervasive problems with misrepresentation and selective citation of the scientific literature, cherry-picking of data, and faulty or absent statistics.”
Cleetus said Tuesday that “EPA is trying to bury the evidence on human-caused climate change, but it cannot change the reality of climate science or the harsh toll climate impacts are taking on people’s lives... This isn’t just about data on a website; it’s an attack on independent science and scientific integrity.”

The ‘COP of Truth’ Just Normalized a New Kind of Climate Denialism
The new denialism no longer bellows about hoaxes; it asks for more studies, more modelling, more consultations, always in the service of delay.
Dec 02, 2025
Belém promised a “COP of truth.” What unfolded was a courteous unravelling of ambition, as denialism left global climate action wobbling at the moment it needs steel.
As the Chair of the UK’s COP30 youth delegation, I realized within hours that this United Nations climate conference would be defined by its optics—not its outcomes. The venue teemed with political hopefuls more interested in cameras than commitments, and with a record 1,600 fossil fuel and 531 carbon-capture lobbyists, 1 in every 25 attendees served commercial interests.
Then came the negotiations, where delegates quietly diluted the science. References to the Intergovernmental Panel on Climate Change (IPCC), long regarded as the global lodestar of climate knowledge, were either softened into ambiguity or dropped altogether. Several companies went even further, trumpeting improvements in emissions intensity as if they were genuine reductions.
It was greenwashing par excellence, a polite fiction to excuse keeping emissions exactly where they are.
After the failures of COP29 and COP30, the process will only matter again if governments are finally pushed toward honesty and supported by tools that can hold them to it.
So it was no surprise when the negotiations titled toward erasure, governing not just the deal but the language that framed it. The term “fossil fuel” vanished from the final Belém Political Package, replaced with sweeping and unenforceable vows to renewables and adaptation funding.
We should have foreseen how settled climate science would be twisted and spun. After all, one investigation found more than 14,000 pieces of COP-related disinformation in just the three months before Belém. Much of it was generated by AI, including a widely shared fake video that showed the host city swallowed by floods.
This version of climate denialism reveals the moral credibility of climate action is being leveraged to keep emissions frozen in place. It no longer bellows about hoaxes, except by Donald Trump who has happily dragged America back into isolationism. In the diplomatic world it asks for more studies, more modelling, more consultations, always in the service of delay. It is denialism wearing the mask of governance, and it is far more corrosive than the loud bluff it replaced.
The timing could hardly be worse. The IPCC’s carbon budget for a 50% chance of staying below 1.5°C will vanish by 2029 if emissions continue at today’s pace. This is also the first year after the Global Stocktake that mandates governments to draft national plans that will set our course until 2030.
And what happens now determines the shape of the decisive decade. Crossing 1.5°C sharply raises the risk of irreversible cryosphere collapse—rapid ice loss in Antarctica and Greenland which will lock the world into meters of sea-level rise that imperil coastal megacities across every hemisphere. At 2°C, another billion people will face severe water scarcity—especially in the Global South where adaptation capacity is lowest and exposure is highest. This reality is why the deliberate sidelining of climate science is not just exasperating but catastrophic.
And COP30’s lone nod to honesty—the Declaration on Information Integrity—feels painfully thin. The declaration, which promises to counter climate falsehoods, was only signed by 12 countries. And with no sanctions or accountability, it is a gesture at truth in the exact moment truth needed teeth.
We need a global firewall for climate truth: binding rules for climate information, a UN body capable of verifying data with transparent AI, and legal duties on platforms to curb the algorithmic spread of lies. Climate inaction is becoming a matter of legal liability. That burden should fall equally on those who deliberately twist the science.
There must be a counterweight capable of tracing disinformation, naming the culprits of confusion, and dragging the debate back to the science that anchors it. Only then can we hope to restart global climate momentum. And in an irony worthy of our age, the technology that helped generate the mess—AI—may be the only thing sharp enough to cut through it.
According to Sachin Dev Duggal, Britain’s foremost expert on applied artificial intelligence and EY’s Entrepreneur of the Year in 2023, the internet is now a space where reliable information sits beside convincing fabrications, and no amount of earnest climate communication will fix this without tools that can separate accuracy from invention at scale.
AI is already showing what those tools might look like. It can review millions of words in seconds and test claims against established climate data with a consistency no human team can match. We are already seeing this in practice. For example, the machine-learning model ClimateBERT has analysed corporate reports and exposed misleading emissions claims. Another model, CLIMINATOR, has also been trained to hold political and corporate actors to account by checking whether their climate statements align with the evidence or contradict it. And the FactCrisis project, cofounded by the EU, has used AI during heatwaves to track false statistics and identify accounts pushing them, offering a glimpse of what becomes possible when AI and international bodies finally start reinforcing one another.
Duggal argues that the next step is a decentralized verification model. Climate data from satellites, sensors, and national inventories would sit in a shared public ledger that no ministry or corporation can quietly revise. When a government or company makes a claim about progress, anyone could check it against a record that does not bend to convenience. It would make the small acts of creative reporting that feed climate denialism far harder to get away with.
Yet today’s AI carries a flaw that limits its usefulness. Large language models are fluent but ungrounded, reproducing the language of climate science without retaining the facts that give it weight, which makes them unreliable referees in a space awash with motivated distortions. Duggal sees that any serious AI tool must reconnect claims to their evidence, trace where the data came from, and reveal the steps that turned information into a conclusion. This is the direction of his SeKondBrain project, which concentrates on how to build these evidential scaffolds so that an AI system can point to the exact documents, numbers, or assumptions that shaped its judgement. That kind of traceability matters because it gives climate negotiators and regulators something concrete to interrogate. And without systems built to preserve and expose the evidence behind their outputs, AI will remain too opaque to play any serious role in protecting science.
After the failures of COP29 and COP30, the process will only matter again if governments are finally pushed toward honesty and supported by tools that can hold them to it. Without that basic partnership, we may have reached the point where another COP has nothing left to say.

Property Insurance Is the Canary in the Climate Coal Mine
We too have a little bird trying to call our attention to a major problem. That bird is the insurance industry with its army of actuaries.
Nov 18, 2025
As the cost of insuring our houses escalates around the United States and the world, it appears that property insurance is acting like a canary in a coal mine.
Canaries used to be taken into coal mines because they served as an early warning system if dangerous gases were building up. Since the canaries were more sensitive to these gases than people, they protected the miners from life-threatening conditions. When the canary dropped dead, the miners could still get out.
Like the canaries, the actuaries who interpret data for insurance companies are more sensitive than most individual people to changes going on in the world. Actuaries earn big salaries because the financial health of their employers depends on them.
Things have already gotten so bad that the National Academies of Sciences, Engineering, and Medicine (NASEM) recently sponsored a webinar panel discussion: "Extreme Weather Events and Insurance: Households, Homeowners, and Risk." (This link will take you to a video of the event.)
Any coal miner who refused to evacuate a mine when the mine’s canary keeled over—perhaps saying, “I don’t believe there is any real danger here”—would not have been long for this world.
The panelists were located in the United States (Washington, DC and Madison, Wisconsin) and England (London and Cambridge). Climate changes are not limited to the United States, nor is awareness that we need to do something about them if we can.
The panelists were not grinding particular political axes. They were discussing the measured fact that an increasing number of extreme weather events are destroying valuable property—housing, commercial buildings, streets, bridges, etc.—requiring insurance company payouts to policyholders.
These insurance payouts must be financed by the premiums charged to people who are insuring their property. As damages increase, the premiums also have to increase. Although premiums may be regulated by state regulators, if they do not allow the needed increases insurance companies will pull out of doing business in that state.
As insurance companies pull out, it may become more and more difficult—perhaps even impossible—for people to insure their houses. But if a house cannot be insured, banks won’t finance a mortgage on it, and if it cannot be financed the owner may be unable to sell it.
For many people, their home is their primary investment, and they cannot afford to live in it if they cannot insure it. If it burned down or was otherwise destroyed, they would be wiped out financially. But if they cannot sell it, then the homeowner is a real pickle.
Disrupted housing markets can produce disastrous results for a country’s economy in general, as we Americans discovered during the recession beginning around 2008.
The impact of a world that is heating up is not being felt as much in the United States as in many other countries in Europe, Africa, and Asia which are suffering from unusually long bouts of very hot weather, flooding downpours alternating with extreme droughts, forest fires, etc. Some island nations may be literally wiped out as melting icebergs and glaciers increase sea level, putting them underwater.
But enough extreme weather events are already occurring in the United States that the insurance companies must make major increases in their prices.
Any coal miner who refused to evacuate a mine when the mine’s canary keeled over—perhaps saying, “I don’t believe there is any real danger here”—would not have been long for this world.
Americans who continue to politicize discussion of global warming—either denying its existence, its extent, its speed, or its seriousness—will be like that coal miner. We too have a little bird trying to call our attention to a major problem. That bird is the insurance industry with its army of actuaries. We ignore that warning at our own risk, and at the risk of our children and grandchildren.
