The White House has reconstituted the U.S. Global Change Research Program, which tracks climate change and produces the National Climate Assessment. The Trump version will focus on "positive" climate effects and be used to protect fossil fuel companies from lawsuits. www.politico.com/news/2026/07...

The administration has a new climate change office. It’s headed by a climate critic.

The office that produces the National Climate Assessment has been reconstituted, after the administration gutted it last year.

Does El Niño forecasting have their own version of a "hot models" problem? There are currently 13 seasonal forecast ensembles used to predict future El Niño / La Niña. Diversity is good, but there remains broad disagreement among them, with some suggesting all-time records. 🧵

The Trump administration has announced that the US will rewrite past climate reports, in a clear attempt to erase scientific history and undermine the consensus on human-caused climate change.

Lots of previously unreported allegations in the lawsuit, including how NOAA also terminated a cooperative agreement with UCAR at the same time as the NCAR news, and how NSF demanded individual cost accounting for every UCAR employee that attended AMS with only 6 days to turn it around.

Just in: UCAR has filed a lawsuit against NSF, the Commerce Dept, NOAA, and OMB to prevent the dismantling of NCAR, alleging "violations of the Constitution and the Administrative Procedure Act."

Just submitted mine. Have you? There is still time - just email NSF_NCAR@nsf.gov today. ** NOTE: You do not have to be an expert to support NCAR! And you do not need to write more than a few sentences about why weather and climate science infrastructure is important to you, and to our country.**

Daniel Swain@weatherwest.bsky.social · 5mo ago

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]

Page 2 of letter by Daniel Swain. It begins: constructive suggestions regarding how the already remarkable institutional efficiency and societal impact of NCAR could be further enhanced through increased (not decreased) federal support in the years to come.
Please note: To ensure the highest level of technical rigor, this response focuses exclusively on the core atmospheric and natural hazard science topics within the author’s primary domain of expertise; for this reason, I have omitted a response to Topic 4 (Space Weather)."


NCAR weather modeling and atmospheric observing capabilities
a) Management and operations of weather-related observational platforms, modeling and science as a stand-alone activity.
The proposed management of weather-related research as a stand-alone activity is a scientifically regressive path that ignores the fundamental physical reality of the Earth system. Modern atmospheric science has demonstrated (largely, it is worth noting, due to groundbreaking researc

The American Academy of Actuaries warns that dismantling NCAR would degrade the catastrophe models insurers depend on to price climate risk—driving up premiums and threatening coverage availability nationwide. "Uncertainty carries a positive cost." www.riskmarketnews.com/trumps-clima...
