On the good news side for #saveNCAR, last week the Senate science committee reported the Weather Research and Forecasting Innovation Reauthorization Act of 2026 (S. 3923) with a @rosen.senate.gov amendment to block NSF from breaking up NCAR for at least 60 days.

AMS Responds to NSF Regarding the Future of National Center for Atmospheric Research (NCAR) YouTube video by American Meteorological Society

The National Center for Atmospheric Research (NCAR) is a cornerstone of U.S. weather science. AMS urges a transparent, community-driven review before restructuring such critical infrastructure.

Boulder Congressman calls for investigation of NSF processes to reorganize NCAR In weather, significant outbreak of severe storms and potential intense tornadoes expected today, focused on lower Great Lakes region

News: Congressman Neguse of Boulder CO region says whistleblower reported to him that OMB is already negotiating specific transfers of pieces of NCAR to private companies, raising legal/ethical issues and undermining NSF process of requesting input on NCAR reorganization. tinyurl.com/2s4jftv3

The NSF has provided no evidence to justify dismantling the National Center for Atmospheric Research (NCAR). Doing so would undermine one of the nation’s most vital scientific institutions. @ncar-ucar.bsky.social

The highly specialized nature of the NCAR-Wyoming Supercomputing Center (NWSC) infrastructure represents an extraordinary value proposition that cannot be replicated by combining it with more generalized NSF programs.

Far more than just an office building, NSF NCAR Mesa Lab is an iconic and purpose-built facility designed specifically for the study of atmospheric science. Its position at the physical interface of the Rocky Mountain foothills and the Great Plains is a deliberate reflection of its mission, serving as a visible symbolβ€”in an iconically American settingβ€”of the federal government's enduring commitment to science in service of society. For many in the field, including myself, the Mesa Lab holds singular importance as a focal gathering point for the global atmospheric science community. My own early career exposure to weather and Earth system modeling, in fact, occurred within these walls, and I have long felt that the facility’s architecture and location inspire a necessary sense of awe regarding the atmosphere’s complexity a

I just submitted my letter to NSF responding to its proposal to dismantle the National Center for Atmospheric Research (NCAR). I argue that doing so would be an astonishing and avoidable misstep, and that federal support for the institution should in fact be *increased.* [1/4]

What so many seem not to understand is that if you start breaking everything into separate entities, you lose any efficiency and additive benefits you had by having them all as a single NCAR.

It's worse than shooting ourselves in the foot. It's significant amputations when there's no infection.
