The federal government once funded some of the most comprehensive research on the planet into the economic costs of climate change. That work is now being systematically dismantled, defunded, and in some cases erased from public servers. The consequences won’t be abstract. They’ll show up in insurance premiums, infrastructure failures, agricultural losses, and the price of rebuilding after the next hurricane.
According to The Guardian, the Trump administration has moved aggressively to shut down federally funded climate damage research programs across multiple agencies, targeting not just future funding but the institutional memory that makes such research possible. Scientists have been reassigned. Grants have been frozen or rescinded. Databases that quantified the financial toll of extreme weather events — tools used by city planners, insurers, and the military alike — have gone dark or been quietly archived without public notice.
This isn’t a budget dispute. It’s the deliberate removal of a knowledge base that took decades to build.
The scale of what’s being lost deserves close examination. The federal government, through agencies like NOAA, NASA, the EPA, and the Department of Energy, has long maintained research programs that estimate the economic damages caused by rising temperatures, sea-level rise, drought, flooding, and wildfire. These aren’t speculative exercises. They inform the social cost of carbon — a metric used in cost-benefit analyses for federal regulations — and they underpin everything from flood-zone maps to crop insurance pricing. When FEMA calculates the expected cost of a disaster, when the Army Corps of Engineers decides where to reinforce a levee, when a state transportation department budgets for road maintenance in a hotter climate, the numbers trace back, at least in part, to federally funded research.
Now much of that pipeline is being severed.
The Guardian’s reporting details how researchers at several agencies were told their projects would not be renewed, with little explanation beyond vague references to “reprioritization.” Some scientists described being instructed not to use the phrase “climate change” in grant applications or internal communications — an echo of similar restrictions imposed during the first Trump administration, but broader and more systematically enforced this time. One researcher, who spoke on condition of anonymity for fear of retaliation, told the outlet that entire teams had been dissolved and their data moved to servers with restricted access.
The timing is striking. Global insured losses from natural catastrophes hit $145 billion in 2025, according to Swiss Re, making it one of the costliest years on record. The United States bore a disproportionate share of those losses. And the trend line is unmistakable: weather-related disasters are becoming more frequent and more expensive. The very moment the data is most needed is the moment it’s being pulled away.
So who fills the gap?
The private sector, to some extent. Reinsurance companies like Munich Re and Swiss Re have their own climate modeling teams. Consulting firms sell risk assessments to corporations and municipalities. But these are proprietary products, not public goods. A small town in Louisiana trying to decide whether to elevate its water treatment plant doesn’t have a subscription to a $200,000-a-year risk analytics platform. It relies on federal data. Or it did.
Academic researchers are scrambling to preserve what they can. Several universities have launched efforts to mirror federal climate datasets before they disappear, a reprise of the data-rescue initiatives that sprang up in 2017. But archiving raw data is one thing; maintaining the institutional capacity to update, interpret, and apply that data is another. “You can save the files,” one climate economist at Columbia University told reporters. “You can’t save the team that knew what to do with them.”
There’s a legal dimension too. Environmental regulations that rely on climate damage estimates are now vulnerable to challenge. If the underlying research has been defunded or discredited by the very government that produced it, opponents of regulation gain a powerful argument in court: the science, they can claim, is no longer supported by the federal government’s own findings. This has already begun to play out in litigation over EPA emissions standards, where industry lawyers have cited the administration’s withdrawal of climate research as evidence that the regulatory basis is unsound.
And the international implications are significant. The United States was, until recently, the single largest contributor to global climate damage research. Other nations — particularly developing countries that lack the resources to conduct their own large-scale studies — depended on American data to inform adaptation planning. The Intergovernmental Panel on Climate Change draws heavily on U.S.-funded research for its assessment reports. Remove that input, and the global picture becomes less complete, less reliable, and harder to act on.
None of this is happening in a vacuum. The administration has simultaneously pulled the United States out of the Paris Agreement again, rolled back vehicle emissions standards, expanded oil and gas leasing on federal lands, and proposed deep cuts to NOAA’s budget. The defunding of climate damage research fits within a broader strategy: if you can’t see the cost, you don’t have to pay it. Or at least, you don’t have to acknowledge it.
But the costs don’t vanish because the research does. They just become invisible — until they aren’t. Until a city discovers its stormwater system can’t handle rainfall intensities that have shifted beyond historical norms. Until a farmer finds that crop insurance premiums have spiked because actuaries, lacking updated federal data, have widened their uncertainty margins. Until a coastal homeowner learns that the flood maps guiding their mortgage were based on data that stopped being updated three years ago.
The insurance industry is watching this closely. Executives at several major carriers have privately expressed alarm at the erosion of public climate data, according to reporting from Reuters. Insurers don’t have a political dog in the climate fight — they have a financial one. Bad data means bad pricing. Bad pricing means either unexpected losses or premiums so high that coverage becomes unaffordable. Both outcomes are destabilizing.
State governments are beginning to respond. California, New York, and several other states have announced plans to fund their own climate damage research programs, but these are patchwork solutions. Climate doesn’t respect state lines. A drought that starts in the Colorado River basin affects water supplies in seven states and Mexico. A hurricane that forms in the Gulf doesn’t care whether Louisiana has its own modeling team. Federal coordination existed for a reason.
There’s a deeper irony at work. The social cost of carbon — the metric most directly threatened by the research shutdown — was originally developed not by environmentalists but by economists working within the federal government to ensure that regulations were cost-effective. It was, in its conception, a conservative tool: a way to make sure the government wasn’t spending more to prevent climate damage than the damage itself would cost. Eliminating it doesn’t make regulation more rational. It makes regulation blind.
Some in Congress have pushed back. A bipartisan group of senators introduced legislation earlier this month that would protect federal climate data from political interference and mandate continued funding for damage assessment research. But the bill faces long odds in a chamber where climate policy remains deeply polarized, and the administration has signaled it would veto any such measure.
Meanwhile, the researchers themselves face an uncertain future. Many have left government service entirely, taking positions at universities or in the private sector. Others remain but have been reassigned to unrelated projects. The brain drain is real, and it’s accelerating. Rebuilding these teams — assuming a future administration wants to — will take years. Possibly a decade. The expertise isn’t something you can hire off the shelf.
What’s being lost isn’t just data. It’s the capacity to understand what climate change is actually costing the American economy, in dollars, right now, every year. It’s the ability to plan. To budget. To make informed decisions about where to build, what to insure, and how to allocate limited resources. That capacity was painstakingly assembled over 30 years by thousands of scientists, economists, and engineers working across dozens of federal agencies.
Dismantling it took months.
The question now is whether the country will recognize what’s gone before the next disaster makes the absence impossible to ignore. History suggests it won’t. The pattern is familiar: defund the warning system, suffer the consequences, then spend far more on recovery than prevention would have cost. It’s an expensive way to learn a lesson. But it may be the only way left, now that the research designed to teach it has been quietly swept away.
