The Trump administration has issued a stop-work order to U.S. government scientists, effectively excising them from the Intergovernmental Panel on Climate Change\u2019s (IPCC) next major report, due in 2029. The decision pulls American expertise and funding from a process that\u2019s long leaned on both to prop up its dire pronouncements. For those who\u2019ve watched the IPCC churn out one overheated forecast after another, there\u2019s a certain satisfaction in seeing the climate establishment forced to limp along without its biggest benefactor.<\/p>\n\n\n\n

The directive halts federal scientists\u2019 contributions to the IPCC\u2019s seventh assessment report, a multi-volume undertaking that typically mobilizes thousands of researchers across years to paint a picture of imminent catastrophe. NASA\u2019s chief scientist, Kate Calvin, was tapped to co-chair an international meeting in Hangzhou, China, next week, where the report\u2019s scope was to be hammered out. That\u2019s off the table now, and the meeting itself hangs in limbo\u2014organizers must be wondering how to proceed without one of their star players.<\/p>\n\n\n\n

\n

\u201cDr. Calvin will not be traveling to this meeting,\u201d a NASA spokesperson said. NASA denied CNN\u2019s request for an interview with Calvin.

An unnamed scientist involved in the effort told CNN they\u2019re unsure what this means for the planned work. One imagines the uncertainty stings a bit more when your whole career\u2019s been hitched to the IPCC wagon.<\/p>\n\n\n\n

\n

The person involved in the report told CNN they were \u201cnot sure what this means for the planned work going forward, or if US scientists will participate in the writing of the IPCC reports.\u201d

The U.S. has historically been a pillar of the IPCC\u2019s operations, supplying not just talent but a hefty chunk of the budget needed to keep its machinery humming. These reports\u2014laden with warnings of soaring temperatures, melting ice caps, and \u201cdeadly, costly consequences\u201d\u2014have been the bedrock of global climate policy, from the Paris Agreement (promptly abandoned by Trump on day one of his term) to endless rounds of UN summits. The IPCC\u2019s clout depends on its ability to project authority, and American involvement has lent it a sheen of credibility. Without that, the 2029 report risks looking like a thinner, less convincing shadow of its predecessors. Climate advocate Harjeet Singh insists the IPCC remains \u201cunbiased\u201d and \u201cevidence-based,\u201d decrying the loss of U.S. collaboration. Skeptics, meanwhile, might note that an outfit prone to amplifying computer-modeled nightmares over real-world data could use a breather\u2014or at least a reality check.<\/p>\n\n\n\n

\n

\u201cThe IPCC is the backbone of global climate science, providing the world with unbiased, evidence-based insights needed to confront the climate crisis,\u201d said Harjeet Singh, a climate advocate and founding director of Satat Sampada Climate Foundation.<\/p>\n\n\n\n

\u201cThe decision to exclude US scientists significantly undermines this collaborative effort and risks compromising the process at a time when robust climate action is needed more than ever,\u201d he told CNN in a statement.

https:\/\/amp.cnn.com\/cnn\/2025\/02\/21\/climate\/trump-blocks-scientists-ipcc<\/a><\/p>\n<\/blockquote>\n\n\n\n

This isn\u2019t Trump\u2019s first rodeo with the climate crowd. His exit from the Paris Agreement in 2017 (and again in 2025) set the tone, and this latest move doubles down on that skepticism. The timing adds a layer of irony: just as the IPCC was gearing up for its Hangzhou confab, the administration yanked the plug, leaving Calvin sidelined and the process scrambling. It\u2019s a dry kind of poetic justice for those who\u2019ve long questioned the IPCC\u2019s track record\u2014think hockey-stick graphs that wobble under scrutiny, Himalayan glaciers that refuse to vanish on cue, or tipping points that keep tipping past their deadlines. The group\u2019s not dead, of course; it\u2019ll soldier on with whatever it can muster from Europe, China, and the usual suspects. But without Uncle Sam\u2019s stamp of approval and deep pockets, the final product might carry less sway\u2014and that\u2019s a prospect worth savoring.<\/p>\n\n\n\n

For the IPCC, the road ahead just got bumpier. The Hangzhou meeting, if it happens, will lack a key voice, and the years-long grind to 2029 will test how well the organization can function on a leaner diet. Trump\u2019s decision doesn\u2019t dismantle the climate machine outright, but it does strip away some of its horsepower. Those who\u2019ve spent decades poking holes in the IPCC\u2019s narrative can sit back and watch the fallout with a quiet grin. The alarmists will howl about \u201cdenial\u201d and \u201csabotage,\u201d no doubt, but the Oval Office isn\u2019t losing sleep over it. Neither, frankly, are we.<\/p>\n\n\n\n
