The Trump administration’s campaign to sideline climate science has turned federal data into a political battleground, with entire archives of temperature records, emissions inventories and sea level projections suddenly at risk. In response, scientists, technologists and even local officials are building a parallel infrastructure to copy, host and defend the numbers that underpin modern climate policy. What began as a scramble to rescue endangered files has evolved into a coordinated resistance that treats climate datasets as democratic infrastructure rather than bureaucratic paperwork.
Instead of accepting a future in which key measurements can be edited or erased by political appointees, researchers are standing up independent repositories, reviving shuttered websites and challenging flawed government reports in public and in court. Their message is blunt: if the White House insists on waging a war on climate information, the scientific community will make that information harder, not easier, to suppress.
The purge of climate data goes from quiet edits to open confrontation
Over the last year, the Trump administration has moved from subtle website tweaks to what one analysis describes as a systemic purge of government climate programs and databases. Agencies that once highlighted rising temperatures and extreme weather now bury or delete those references, while long running initiatives lose funding or are abruptly restructured in ways that weaken their public presence. As one account of this trend notes, In the last year, Trump officials have targeted not just research grants but also the digital infrastructure that made climate information easy for citizens, journalists and local planners to find.
Scientists warn that the most visible deletions are only part of the story, because the government also controls countless internal databases that track everything from Arctic sea ice to wildfire smoke. According to Scientists who monitor these systems, there is growing concern that officials are quietly altering or eroding datasets that never appear on public facing websites at all. That fear has turned data preservation into a race against time, as researchers try to copy vulnerable records before they are changed, archived in inaccessible formats or taken offline without notice.
Data rescue networks race to copy what Washington wants to erase
Faced with the risk that federal servers could be scrubbed or locked down, a loose but increasingly sophisticated network of archivists, coders and researchers has sprung into action. In a high stakes digital tug of war, this scrappy coalition is systematically crawling agency sites, downloading climate and environmental records and rehosting them on independent platforms. One detailed account describes how volunteers have become “data heroes,” racing to rescue files as the Trump administration moves to wipe out key scientific data that is essential for protecting people and the planet.
Some of the most ambitious efforts are building institutional homes for this rescued information so it cannot be easily lost again. The Public Environmental Data Project, or PEDP, emerged in 2024 as a dedicated initiative to safeguard climate and pollution records that might otherwise be deleted or altered. One of its founding members described how the group works with universities and civic technologists to mirror endangered datasets and keep them searchable for the public, a mission that aligns with broader academic repositories such as the Harvard Dataverse that are designed to preserve research outputs at scale. In parallel, the Public Environmental Data Project has become a hub for training volunteers to identify at risk files and move them into safer digital homes.
Scientists rebuild sidelined climate platforms outside government control
As the administration has targeted specific programs, scientists who once worked inside federal agencies are recreating those efforts on the outside. A group of experts who formerly served at the National Oceanic and Atmospheric Administration recently launched an independent site that republishes much of the public oriented climate content that used to live on climate.gov. Their goal is to keep educational tools, extreme weather explainers and long term projections accessible even as official channels are pared back, a strategy detailed in reporting on how scientists are making that material available online again.
Others are reviving or reinventing platforms that the Trump administration tried to shutter outright. After key staff were removed and crucial extreme weather data was cut from official channels, experts who had been fired by Trump helped stand up a new portal that mirrors the old climate.gov content. One of them, Lindsey, explained that Since it was not “technically possible” to strip every piece of “forbidden” climate information from the original site, the administration opted to gut large portions of it instead, prompting the team to rebuild the resource under a new banner that now runs the climate.us slogan. Their work shows how technical expertise and institutional memory can blunt political interference, at least when scientists are willing to operate outside government payrolls.
Trump’s reshaping of official climate reports sparks organized pushback
While data rescue efforts focus on raw numbers, another front in this conflict centers on how the administration interprets those numbers in official reports. President Trump’s second term has been marked by what one analysis calls the destruction of democratic processes that normally insulate science from political pressure, including the sidelining of advisory panels and the manipulation of technical documents. The Union of Concerned Scientists has warned that the first six months of this term were characterized by attacks on the institutions that allow experts to inform policy and hold the administration accountable, a pattern they describe as science and democracy under siege.
That pressure is visible in the way the White House has handled the National Climate Assessment, the congressionally mandated report that synthesizes the latest research on climate impacts in the United States. Earlier in the term, Trump officials dismissed key scientists who were writing the next installment, known as NCA6, and announced that the scope of the report was being reevaluated in accordance with the Global Change Research 1990. At the same time, a separate climate report produced by the administration has been criticized for “cherry picking” data in ways that downplay harmful findings, prompting scientific societies to warn that such selective use of evidence misleads the public about the severity of warming, a concern laid out in detail in a Sep analysis of the report.
Veteran researchers and allies challenge disinformation and censorship
Scientists are not simply grumbling about these moves, they are organizing to confront them in public and in court. Dozens of veteran climate scientists have launched a coordinated response to a Trump administration document that casts doubt on mainstream climate research, arguing that the report misrepresents the underlying literature and ignores key lines of evidence. Their campaign, described in a Dozens of scientists briefing, aims to correct the record before the flawed analysis can be used to justify rolling back emissions rules or sidelining future assessments.
Legal challenges are also emerging as a tool to expose how these reports are written. One lawsuit targets the DOE, Secretary Christopher Wright in his official capacity as head of that department, the EPA and other agencies over the way they assembled a controversial climate document. The complaint argues that the administration relied on a small circle of ideologically aligned advisers rather than the broader scientific community that normally informs federal policy, a charge detailed in a lawsuit that names those agencies directly. By forcing agencies to disclose how they selected authors and sources, plaintiffs hope to deter future attempts to launder political talking points through the language of scientific uncertainty.
