Kate Marvel, a senior NASA climate scientist, has walked away from the agency’s Earth research program, saying political actions have made it impossible for her to keep doing the job she signed up for. In a resignation letter, she wrote, “I never expected that science itself would come under attack.” Marvel said recent upheavals, along with what she described as attacks on science under the current administration, left her unable to remain a publicly funded researcher.
According to a letter seen by Bloomberg, Marvel addressed her resignation to Gavin Schmidt and Ron Miller and framed her exit as a protest against efforts to undermine the integrity of federally funded research.
Marvel is a widely published climate physicist who worked at NASA’s Goddard Institute for Space Studies and has ties to Columbia University. She served as a lead author on the U.S. Fifth National Climate Assessment and wrote the book Human Nature. Physics Today noted that she became a civil servant in 2024 and has long been outspoken about the role of public science in a functioning democracy.
Federal Moves That Escalated Tensions
Marvel’s resignation lands after a series of federal actions that critics say have pushed scientific findings to the sidelines. The flash point was the Environmental Protection Agency’s Feb. 12 decision to rescind the 2009 endangerment finding for greenhouse gases, a move reported by the Associated Press. That step drew immediate legal challenges from states and environmental groups, and CalMatters detailed California’s lawsuit targeting the reversal.
Why Scientists Say The Exit Matters
Experts and science policy groups warn that when a high profile researcher like Marvel heads for the door, it does more than generate a few headlines. They say such departures erode morale inside agencies, make it harder to recruit and retain talent, and complicate the long game of federal research projects that are designed to span decades, not election cycles. Scripps News and other outlets have documented widespread concern among federal scientists, along with growing academic pushback to the cascade of policy rollbacks.
Marvel’s departure now becomes part of the broader fight that will play out at NASA’s headquarters in Washington, D.C., where agency leaders are weighing how recent federal moves affect both policy and public trust. The episode is a reminder that national political choices do not stay in press releases; they ripple through the day to day work of agencies tasked with producing knowledge the public pays for.
