'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.”

Study Shows Glaciers Have Lost '3 Olympic Swimming Pools Per Second' Since 2000
One researcher said the findings support calls "for urgent and concrete actions to reduce greenhouse gas emissions and associated warming."
Feb 20, 2025
An international science project on Wednesday published a study in the journal Nature showing that glaciers have lost an average of 273 billion metric tons of ice annually since 2000—depleting freshwater resources, driving sea-level rise, and underscoring the need for sweeping global action to significantly reduce planet-heating pollution.
The Glacier Mass Balance Intercomparison Exercise (GlaMBIE) team compiled major studies to estimate global mass change from 2000, when glaciers—excluding Antarctica and Greenland's ice sheets—held about 121,728 billion metric tons of ice, to 2023.
The researchers found that during that period, the world lost 5% of all glacier ice, with regional losses for the full two decades ranging from 2% on the Antarctic and Subantarctic islands, to 39% in Central Europe.
That's a loss of 6,542 billion metric tons total or 273 billion metric tons per year, "the equivalent of three Olympic swimming pools per second," noted France's National Center for Scientific Research (CNRS).
Glaciologist Michael Zemp, who co-led the study, said in a statement that the annual figure "amounts to what the entire global population consumes in 30 years, assuming three liters per person and day."
"Every tenth of a degree warming that we avoid saves us money, saves us lives, saves us problems."
Although the researchers highlighted the annual average, they also emphasized that the rate of glacier ice loss "increased significantly" from 231 billion metric tons annually during the first half of the study period to 314 billion metric tons per year in the second half. In other words, the amount of ice being lost surged by 36% between the two ranges.
Zemp, a professor at Switzerland's University of Zurich and director of the World Glacier Monitoring Service, told Agence France-Presse that the findings are "shocking" and warned that many smaller glaciers "will not survive the present century."
Stephen Plummer, an Earth observation applications scientist at the European Space Agency, said that "these findings are not only crucial for advancing our scientific understanding of global glacier changes, but also provide a valuable baseline to help regions address the challenges of managing scarce freshwater resources and contribute to developing effective mitigation strategies to combat rising sea level."
The ice loss over the GlaMBIE study's full timeline led to about 18 mm or 0.7 inches of sea-level rise. The researchers projected future losses that lead to 32-67 mm, or 1.26-2.6 inches, of sea-level rise by 2040.
"We are facing higher sea-level rise until the end of this century than expected before," Zemp told AFP, referring to the latest projection from the United Nations Intergovernmental Panel on Climate Change (IPCC).
"You have to reduce the greenhouse gas emissions, it is as simple and as complicated as that," Zemp said. "Every tenth of a degree warming that we avoid saves us money, saves us lives, saves us problems."
The GlaMBIE project manager, Samuel Nussbaumer, similarly told Oceanographic that "our observations and recent modeling studies indicate that glacier mass loss will continue and possibly accelerate until the end of this century," which underpins the IPCC's "call for urgent and concrete actions to reduce greenhouse gas emissions and associated warming to limit the impact of glacier wastage on local geohazards, regional freshwater availability, and global sea-level rise."
The team's findings were released during the U.N.'s International Year of Glaciers' Preservation and the Decade of Action for Cryospheric Sciences—and they "will feed into the next IPCC report, due in 2029," according to CNRS.
Scientists from around the world who were not involved with the study were alarmed by its revelations—which come after the hottest year in human history and amid humanity's failure to curb planet-heating emissions, largely from fossil fuels.
Martin Siegert, a professor at the United Kingdom's University of Exeter, said in a statement that "this research is concerning to us, because it predicts further glacier loss, which can be considered like a 'canary in the coal mine' for ice sheet reaction to global warming and far more sea-level rise this century and beyond. The IPCC indicates 0.5-1 meters this century—but that is with a 66% certainty—hence 1/3 chance it could be higher under 'strong' warming, which unfortunately is the pathway we are on presently."
Andrew Shepherd, a professor at Northumbria University, another U.K. institution, explained that "glacier melting has two main impacts; it causes sea-level rise and it disrupts the water supply in rivers that are fed by meltwater."
"Around 2 billion people depend on meltwater from glaciers and so their retreat is a big problem for society—it's not just that we are losing them from our landscape, they are an important part of our daily lives," he said. "Even small amounts of sea-level rise matter because it leads to more frequent coastal flooding. Every centimeter of sea-level rise exposes another 2 million people to annual flooding somewhere on our planet."

Climate Tipping Points, Ecological Collapse Could Arrive Sooner Than Expected: Study
"Urgent action is needed now more than ever to prevent a catastrophic ecological collapse," said one campaigner in response to the new research.
Jun 23, 2023
A new study released Thursday warns that international experts may have been overly cautious in their warnings about widespread ecological collapse such as a catastrophic breakdown in the Amazon rainforest, which the Intergovernmental Panel on Climate Change said last year could come by the year 2100.
Scientists at Rothamsted Research and Southampton, Sheffield, and Bangor Universities in the United Kingdom found that as numerous factors such as water stress and pollution from mining compound the degradation of ecosystems in forests and bodies of water, the environments can be pushed toward tipping points more quickly.
The IPCC, suggests the study, which was published in Nature Sustainability, has been issuing its warnings about a tipping point in the Amazon while focusing on just a single factor, such as deforestation or planetary heating. Both of those drivers could interact with other environmental changes and accelerate tipping points such as dieback—in which the rainforest ecosystem would be replaced by one resembling a dry savanna.
"It is not clear whether the IPCC estimate for a tipping point in the Amazon forest before 2100 includes the possibility for interacting drivers and/or noise; if not, our findings suggest that a breakdown may occur several decades earlier," reads the report. "This would occur where local-scale failures in elements (such as species populations, fish stocks, crop yields, and water resources) combine with more extreme events (such as wildfires and droughts) to precondition the large-scale system, already vulnerable to the influence of other large-scale tipping elements, to collapse earlier—a meeting of top-down and bottom-up forces."
The researchers used computer models to assess the potential fates of two lake ecosystems and two forests, allowing for 70,000 adjustments of variables.
In the study, up to 15% of ecological collapses occurred as the result of new events or environmental stressors, even in cases where the primary stress affecting the ecosystem remained at the same level.
At Lake Erhai in southern China, for example, "abrupt lake eutrophication [the presence of excessive nutrients or minerals] was initially perceived to have been driven by transgression of a threshold in nutrient enrichment driven by agricultural runoff but historical analysis has shown that the shift was also affected by lake water-level management, seasonal climate, and fish farming," reads the study.
Because international experts may not have been considering variables such as water resources when they warned that the Amazon is headed for a climate tipping point by the turn of the next century, study co-author Professor Simon Willcock of Rothamsted Research told The Guardian, "We could realistically be the last generation to see the Amazon."
"It could happen very soon," he added.
The scientists said their research shows that even if some aspects of an ecosystem are managed sustainably, preventing stresses including planetary heating and extreme weather events—both being driven by the continued extraction of fossil fuels—is crucial for avoiding tipping points.
"Urgent action is needed now more than ever to prevent a catastrophic ecological collapse," said Tanya Steele, CEO of the World Wildlife Fund in the U.K., in response to the research.
Willcock noted that the study's findings suggest that an accelerated recovery of ecosystems is possible with a multi-pronged approach that would address deforestation, planetary heating, and other stresses.
"Potentially if you apply positive pressure," Willcock told The Guardian, "you can see rapid recovery,"
