"NCAR is not just another research center. It is purpose-built critical infrastructure designed to integrate observations, modeling, supercomputing, and applied research in ways that no single university, agency, or contractor can replicate on its own."

What Americans Lose If Their National Center for Atmospheric Research Is Dismantled: 1. Safe air travel 2. Safe food 3. National security 4. Disaster preparedness 5. National pride Tell your members of Congress to fully fund NCAR

In this compelling piece, originally published at @eos.org, UCS’s @carlonimbus.bsky.social outlines what’s at stake if the Trump administration dismantles the National Center for Atmospheric Research (NCAR). Read it here: act.ucsusa.org/4aiUin9

Tomorrow: UCS's @carlonimbus.bsky.social joins a town hall panel, “Convergence Science: Weaving Traditional Wisdom and Modern Scientific Knowledge for Weather, Water, and Climate Actions.” The session explores how Indigenous knowledge & science can work together to address climate change. ↘️

Former Community Science Fellow @carlonimbus.bsky.social makes the case for #SaveNCAR in a new @agu.org @eos.org op-ed—highlighting why decades of public investment in this critical scientific infrastructure matter for communities, safety, and national pride. Read more here: eos.org/opinions/wha...

My OpEd with @agu.org @eos.org on #SaveNCAR. Please check out what we can do together to speak on the value of this critical infrastructure, and what I believe is a source of American pride possible by over six decades of public investments. Let’s continue to invest in this important public good.

Attention folks in the weather, climate, disaster, wildfire, and Earth science communities: NSF has just published a new "Dear Colleague" letter inviting feedback (by Mar 13) on the proposal to dismantle the National Center for Atmospheric Research (NCAR). www.nsf.gov/funding/...

NSF's "Dear Colleagues" letter about NCAR omits any mention of climate science, opting for language around 'critical weather infrastructure' etc. www.nsf.gov/funding/info...

The National Science Foundation has just released its Dear Colleague Letter (DCL) regarding NCAR and it is gut-wrenching. The deadline to submit comments to the DCL is March 13th. I urge folks to please share and inform NSF on the critical importance of NCAR. www.nsf.gov/funding/info...

Hoping to cast a wide net to find the right candidates for a Science Fellow (2 yr position) @ucs.org . Looking for PhD with expertise and interest in working on just land transitions and grid resilience, in California and beyond. job posting: apply.workable.com/j/41E7503CD5...

The Trump admin "has been forced to acknowledge its unlawful actions and release gov. documents related to this case, which will allow the public to see for itself how the DOE and EPA worked in concert to solicit a report with predetermined conclusions aimed at overturning the Endangerment Finding."

Do you know anyone who'd be interested? Pls share! @debrakrienstra.bsky.social @corinanewsome.bsky.social @carlonimbus.bsky.social @samuelytchiu.bsky.social @revfredsmall.bsky.social @dianabutlerbass.bsky.social @climate-brian.bsky.social @robertmcclellan.bsky.social biologos.org/creators-for...

“Dismantling an institution so central to weather forecasting and climate change prediction would not only undermine scientific research, it would leave people across the nation less prepared for the dangers of a warming world,” says Carlos Martinez of @ucs.org www.latimes.com/environment/...

The Trump Administration's plan to dismantle the @ncar-ucar.bsky.social is senseless & dangerous. It would weaken weather forecasting, climate research, & the science that keeps people safe. We urge that this plan be abandoned. Call Congress to #SaveNCAR today. buff.ly/7ka1BQA

🚨 Late breaking update! 🚨 We'll be joined by @neguse.house.gov, who will be giving brief remarks on news of threats to NCAR during this #AGU25 session at 5:30 CT in E-2. Join us!

@ucs.org has released a letter you can write to your Congressperson to save @ncar-ucar.bsky.social Share your voice on the significant value of this bedrock climate and weather insitution. Your story matters! secure.ucs.org/a/2025-prote...

At #AGU25 and concerned about news of NCAR dismantling? Join us today 4pm CT. We'll cover independent science action and discuss the key science functions we need the government for--like the critical functions that NCAR provides on weather and climate research. agu.confex.com/agu/agu25/me...

"Without NCAR’s infrastructure + supercomputing abilities, many small colleges & universities wouldn’t be able to do research with the latest models. NCAR research influences every piece of weather & climate prediction in the US: air quality, droughts, hurricanes + more." - @carlonimbus.bsky.social

"Deliberately dismantling an institution so central to weather forecasting and climate change prediction would not only undermine scientific research, it would leave people across the nation less prepared for the dangers of a warming world." Said @carlonimbus.bsky.social.

@ncar-ucar.bsky.social provided the pathway to turn my curiosity about weather into a professional reality. It’s resources & data has benefited the earth science community and the general public. Dismantling this public good would be outrageous. My @ucs.org statement: www.ucs.org/about/news/t...

At @agu.org next week? Excited to join @gretchentg.bsky.social for a session on Independent Science & check out our fun swag and information about @ucs.org & our sessions at booth #684! #AGU25

The Trump administration has removed scientific data and climate change information from US Environmental Protection Agency (EPA) webpages, including all references to human activities driving climate change.

In times like these, when our government is trying to suppress dissenting voices, I'm grateful to lead an organization that is independently funded by @ucs.org members, not beholden to government or corporate dollars. Help us preserve that independence this #GivingTuesday. ucs.org/give-science

UCS’s @carlonimbus.bsky.social sits down with @wedonthavetime.bsky.social at #ClimateWeekNYC to discuss the 2nd Trump administration's attacks on science and use of climate disinformation to undermine critical public health protections.

🚨 NCA5 is now LIVE! 🚨 They took it down, but we've brought it back at: nca5.climate.us Bookmark. 👏 this. 👏 page. 👏 This is just our first step in restoring trusted science information that Americans need to understand what's happening with the climate.

📣The report says EPA’s Endangerment Finding was “accurate, has stood the test of time, and is now reinforced by even stronger evidence. Much of the understanding of climate change that was uncertain or tentative in 2009 has now been resolved by scientific research.” bit.ly/4mp2kxI

The comment period for a sham “climate science” report commissioned by the DOE closed earlier this week, and the verdict is in: the scientific community has overwhelmingly and resoundingly rejected the report. UCS submitted comments on the report, and here are the four key points we made:

Our department (Berkeley PMB) is hiring an asst. prof. in Plant Resilience to Climate Change! aprecruit.berkeley.edu/JPF05049

Today, I alongside colleagues of @ucs.org have submitted our public comments to the DOE report that completely undermines climate science and misinforms the American Public about climate change and its impacts to our well-being and our environment.

The Department of Energy hired five academics to raise doubts about climate change. 85+ climate experts (organized by @andrewdessler.com) reviewed their report. Our conclusion, detailed in 450 pages of analysis: it is biased, full of errors, and not fit to inform policy making.

Great article in the NYTimes about our comment to the DOE about their climate report. Gift link: www.nytimes.com/2025/09/02/c...

More than 85 scientists say that a recent U.S. Department of Energy report is full of errors and misrepresents climate science.

Our comment on the DOE CWG report is done. It tips the scales at 439 pages, approx. 3x longer than the DOE report. This is related to Brandolini's law: The amount of energy needed to refute bullshit is an order of magnitude bigger than that needed to produce it. Example: refuting one sentence.

A new study found that the United States was responsible for 55 percent of the pollution emitted by private jets globally.

I’ve been an author of the national climate assessment since the Bush administration. It is an incredible one-stop shop for climate info. Download the PDFs of NCA5 here:

Our final updates have been posted to the Climate.gov website, and this will be our final post to our social media channels.

Check out this article in AP on the Trump admin permanently shutting down SSMIS, which provides essential data for hurricane forecasters. ‘“What happened this week is another attempt by the Trump administration to sabotage our weather and climate infrastructure,” Alessi said.’

Notably, websites like heat.gov, drought.gov, and weather.gov remain untouched. So why target Climate.gov? My take: it’s a troubling attempt to bury vital climate science, making it harder for the public to easily access and use this information.
