Thanks to the Trump administration, you can now just decide that you don’t know things—even if you do know them, @petridishes.bsky.social writes:

All of this is spot-on, but @andrewdessler.com's final point is the most critical from a climate science perspective. The DOE report was their best shot against mainstream climate science. It failed miserably and publicly when put to the acid test of legal acceptability.

In their final Endangerment Finding rule, EPA dropped their reliance on the DOE climate report "in light of concerns raised by some commenters." Despite their best effort, when it mattered most, EPA has effectively and officially conceded that the consensus climate science is correct. 🍾‼️

Here's the link to the actual rule rescinding the Endangerment Finding and vehicle GHG standards, for all those interested: www.epa.gov/regulations-...

Another excellent essay by @vermontgmg.bsky.social about ICE/CBP, this one about their use (or abuse) of masks. www.doomsdayscenario.co/p/ice-s-mask...

Political appointees could *always* override the civil servants. It's just that the politicals hate being embarrassed when lowly civil servants show that the politicals' 'evidence' is fabricated, wrong, and contrary to law. No reason for this rule beyond the fear of being outed as frauds.

Great to see my former colleague Bryan Hubbell is wasting no time in contributing to important work at @rff.org with this excellent report on the Zeldin EPA's decision to ignore the monetized health benefits of reducing air pollution.

Thrilled to see this paper, especially by someone with the stature of @gruberte.bsky.social. The inability to linearly reduce production to zero (or even close) is an issue that's been ignored by big energy system analyses and has enormous implications for energy and petro products more broadly.

The problem of ICE/CBP reform is we have a monster rampaging through our democracy and are trying to restrict *which* cities it can pillage and *how many* civilians it can eat. The problem isn’t the restrictions on the monster; the problem is the monster. www.doomsdayscenario.co/p/six-ways-t...

Nevermind the jobs you had, tell me five classes you took in college: Advanced Thermodynamics Automatic Control Systems Managerial Economics Social Dance* German I* *Great lessons in why I should stick with engineering

EDF has posted a collection of internal emails and other files from the DOE Climate Working Group, gathered during their recent court case that found the DOE violated the Federal Advisory Committee Act. No major surprises, but a few interesting takeaways. 🧵 [1/10] www.edf.org/media/newly-...

The fact that the panel did not follow the law regarding advisory committees only scratches the surface of their disregard for policies governing scientific information quality (or lack thereof, in this case).

They've painted themselves into a corner. They either drop the scientific argument and implicitly agree that the consensus science is right, or they bet on the justices agreeing that they (EPA) can define the science as they please, which seems unlikely, even with the current SCOTUS.

I wrote about the brain drain.

And this may well undercount those who have left because of Trump. The numbers don't include December 2024 (or 2025). December's a popular fed retirement month, so I expect more left in Dec 2024 via retirement, knowing what was coming.

If you want to know about climate change and EPA's (former) work to address it, follow @marcusmarcusrc.bsky.social. One of the sharpest (and nicest!) guys around.

I think if anyone were serious about climate philanthropy they would just buy this building and hire every single NCAR employee and call it a day

Greenland to the US: "You want a piece of me? Let's see who invades who." (Apologies to those who may be harmed by the sourcing)

A great explainer from @vermontgmg.bsky.social about the differences between ICE, CBP, and investigators and why they're exactly wrong for good law enforcement.

🥇Thread of the year candidate!

For those of us who try to understand the world, this thread by @matthew.flux.community helps us understand those who don't.

This IS indeed very much worth reading. [Gift article] www.nytimes.com/2026/01/18/o...

An excellent summary of how the Trump administration is systematically undermining evidence-based policies across the government: "The real damage happens before anyone is told to lie" Pretexts and Pressure open.substack.com/pub/scilight...

Rep. @seancasten.bsky.social once again shining a light on the reality of how stuff really works.

Over and over again, these guys demonstrate that the only way they can win is by cheating.

In 2025, Trump’s EPA team abandoned public health and the environment. In 2026, we turn the tide. Check out the Environmental Protection Network's substack: environmentalprotectionnetwork.substack.com/p/in-2025-tr...

Important points from @amgcarlton.bsky.social. Brief and to the point. These actions apply to government science agencies as well.

That heaviness you feel after events like yesterday is real. We've all accumulated a lot of mental and emotional weight in the first year of Trump's disastrous presidency. www.doomsdayscenario.co/p/the-physic...

Don't forget folks: allowing yourself a vision of the future you'd want for our country and planet - not the one you'd settle for, not the one you fear, but the future of your dreams - isn't naive, it's a vital cognitive skill. That's how we articulate what we most value. What's worth fighting for.

I'm sure they can use Grok to write it and have Claude and Gemini provide the reviews.

All of the people mentioned in the article don't work for the federal government AFAIK, and the U.S. Global Change Research Program's staff and infrastructure have been gutted. Who from the federal government is actually leading this new Grok NCA?

Alas, but no surprise. bsky.app/profile/andy...

How General Sherman carried out a once-unthinkable transformation of Atlanta.

This Yglesias piece in the NYT is horrifically bad. Almost every "fact" it cites is provably false. At best it is cocktail party banter from a pundit who knows nothing of energy. At worst, it was cut/paste from oil industry talking points. So, a rebuttal: www.nytimes.com/2025/12/18/o...

Great job by @climate.us to highlight that communicating about climate change requires more than data.

A fitting analogy. Russ Vought is simply a Taliban in a suit.

Hearing this is payback for Colorado not honoring Trump/Peters ‘pardon’

Literally shaking my head. The baseless, naive, shortsighted mischaracterization and vilification of my career field by egomaniacs and narcissists is sending me. I’ve worked with NCAR scientists for 34 years. Some of the best atmospheric science research in the world includes NCAR collabs. Why? 😢

NSF is about to dismantle NCAR at Russell Vought's direction to protect the fossil fuel industry. It's hard to communicate just how much NCAR does, so let's take a look: I've never worked at NCAR, and I've worked with NCAR researchers once ever. What scientific discoveries has NCAR made possible? 👇

This would be a huge win. This was their chance to put their "red team" views into the official record and the best they could do was to present an epic failure. They'll claim it was just ideological opposition, but in the end their view of the science crashed and burned in front of everyone.

It's gonna be interesting to see the results of this summer's natural experiment regarding attendance at World Cup matches, held in the US, Canada, and Mexico.

Maybe they're still in the process of removing references to human causes of climate change, but it's not totally erased: "Human activity is responsible for almost all of the increase in GHGs over the last 150 years. The primary sources are from burning fossil fuels." It's not as easy to find, tho.

"Reverse malicious schemes to hide truth and information from Americans" Oh. You mean like shutting down the US Global Change Research Program's website, with all the National Climate Assessments? I guess we can expect to see the site back up and running in the next day or so... No shame at all.

One of the best researchers at EPA has a physics degree. And she's demonstrated excellence in guiding policies and public outreach, showing that a physics background is useful in areas well beyond research. AND, we'll get past this irrationality. Research will be back.

A crucially important, and generally unappreciated, point from @sundogplanets.mastodon.social.ap.brid.gy: Reflect Orbital is "simply a reckless and inefficient use of Earth orbit, a precious and finite resource." Check out her thread on Mastodon.

Spot on.

Completely agree with @kellyhereid.bsky.social's take on @scrawford.bsky.social's excellent article. The potential for private sector firms to discontinue providing critical info has been long recognized in the climate services space (of course, now this Administration is doing the same thing).

Hard to beat David Keith's quote: “total, unadulterated bulls---,” referring to Stardust's claims of a lack of toxicity of their particles. _All_ particles cause harm when inhaled. Stardust is being irresponsible in nearly every way possible. www.washingtonpost.com/climate-solu...

This is the challenge with relying on proprietary data and models to support what needs to be public information.
