The Trump administration has removed references to human-caused climate change and key scientific data from EPA websites, alarming climate scientists and health experts.

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.

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 per cent 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 on 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.”
