In the first two weeks of President Donald Trump’s second term, the administration has begun to scrub critical environmental resources and datasets from federal agency websites. To combat this effort to suppress and censor public data, the National Security Archive’s Climate Change Transparency Project today ( Feb. 06) publishes a selection of materials on climate change and environmental justice that have been deleted from agency web pages and spotlights the environmental and archivist organizations working to identify, scrape, and preserve these critical data.
During President Trump’s first term, organizations like the Environmental Data and Governance Initiative (EDGI) documented the administration’s widespread campaign to suppress climate and environmental data, like when it deleted all webpages, fact sheets, and emissions and financial incentives calculators related to President Obama’s 2015 Clean Power Plan. Since the 2024 presidential election, EDGI and environmental advocacy organizations alike have anticipated the targeting of federal environmental and climate data and have been archiving datasets and preparing to rebuild public access to web tools.
So far, one of the most glaring deletions from the current administration has been the removal of the White House pages on the Council of Environmental Quality (CEQ) and the Office of Science and Technology Policy (OSTP), divisions within the Executive Office of the President that coordinate federal environmental and scientific efforts and work closely with federal agencies and other White House offices on environmental energy policies and initiatives.
During the Biden administration, CEQ—an office established in 1969 by the National Environmental Policy Act (NEPA) under Republican President Richard Nixon—created the Climate and Economic Justice Screening Tool (CEJST), a public web tool which allowed users to locate communities in the U.S. facing marginalization and disproportionate climate and pollution impacts. The current Trump administration has already removed access to the tool and to CEQ’s webpage on the White House website. Three days after the CEJST was taken offline, EDGI and fellow members of the Public Environmental Data Partners (PEDP) posted an “unofficial but functional copy” of the tool, restoring public access for the time being.
The website of the Environmental Protection Agency (EPA)—which Trump sought to dismantle through a rollback of regulations during his first term and which has seen its authority whittled down by a more conservative Supreme Court—experienced its own overhaul last week when the administration deleted all references to climate change from its homepage and other prominent parts of the site. Although the EPA’s “Climate Change Impacts” page still exists, it is buried deep in sections of the website that are harder to find, and the topic of climate change has been removed from the homepage’s “Environmental Topics” section.
Climate change has for years been a cornerstone policy issue for many other agencies as well. This was strengthened during the last four years as the former Biden administration sought to integrate climate adaptation and resilience plans across 20 federal agencies. Under Biden, the State Department’s website had two “Policy Issues” sections on “Climate and Environment” and the “Climate Crisis” filled with documents related to U.S. climate policies aimed at cutting emissions of greenhouse gases like carbon dioxide and methane to meet the terms of the 2015 Paris Agreement. The current “Climate and Environment” page has been pared down and includes no mention of the Paris Agreement (which the Trump Administration officially withdrew from for a second time on his first day in office), and the “Climate Crisis” page has been removed. Now, a search for “global warming” leads to a list of defunct links.
Additionally, the Department of Homeland Security (DHS), the agency currently at the center of President Trump’s immigration executive actions, removed several of its “In Focus” topics including a section called “Addressing the Climate Crisis.” Previously, users could access information on “FEMA Floodplain and Flood Map Resources,” guidance on extreme temperatures and heat tools, and reports like the agency’s “Strategic Framework for Addressing Climate Change” and its “Climate Action Plan.” Now, along with the removal of the “Addressing the Climate Crisis In Focus” topic, DHS has also removed its pages on “Artificial Intelligence at DHS,” “Deferred Action for Childhood Arrivals (DACA),” “Honoring Veterans,” “Operation Allies Welcome,” and “Securing the Border.”
Notably, the National Oceanic and Atmospheric Agency (NOAA), which may be the next target of the White House’s Department of Government Efficiency (DOGE), still has a live Climate page, including a variety of tools and resources, funding opportunities, and a “Climate 101” section. While unchanged at the time of this publication, the agency’s global climate data distribution system, the National Centers for Environmental Information (NCEI), is undergoing “scheduled maintenance” from February 4-6, according to the banner announcement on the NCEI page. Similarly, the Department of Defense’s website still includes a live and unchanged “Spotlight on Tackling the Climate Crisis,” which states that DOD is “elevating climate change as a national security priority, integrating climate considerations into policies, strategies and partner engagements.” And although key climate information is still spread sporadically throughout the National Aeronautics and Space Administration (NASA) website, the agency’s climate website displays a message about moving to a “more integrated portal on science,” and the word “climate” is removed from its URL.
Most recently, the White House ordered the Department of Agriculture (USDA) to take down all websites referencing the climate crisis, most impacting the United States Forest Service (USFS) website, which previously included key resources, research, and adaptation tools, such as vulnerability assessments for wildfires. At the time of this publication, the USDA’s “Climate Hubs” sites are still live, but sites including the USFS “Climate Change Resource Center,” the “Climate Change Action Tracker,” and the “National Roadmap for Responding to Climate Change” have gone dark.
Since President Trump’s inauguration on January 20, 2025, more than 2,000 datasets have also disappeared from data.gov, the largest repository of U.S. government open data on the internet. (Figure 7) At the time of this posting, there are currently 306,770 datasets available, still over 1,000 fewer than before President Trump assumed office. According to 404 Media, it is still “too early to say what, specifically, has been deleted, though archivists and academics…are working on triaging the situation.”
As these sites and datasets go dark, environmental and archivist organizations, researchers, and citizens are racing to save government resources from vanishing entirely. The End of Term Web Archive Project—an effort that partners with EDGI, PEDP, the Common Crawl, universities, the U.S. National Archives and Records Administration and the U.S. Government Publishing Office—preserves web material from previous administrations through a series of web crawlers that scrape federal websites and data. Every four years, librarians, archivists, and technologists undertake an “end-of-term-crawl” to capture websites that preserve the historical record as one administration ends and another begins. The data collected during the end-of-term crawls lives on the Internet Archive’s Wayback Machine, a longstanding and valuable public tool containing billions of webpages that can be searched and downloaded as bulk data. According to project participants, the initiative aims to safeguard “democracy itself.”
