The federal government is setting itself up to be on the wrong end of the biggest lawsuit in history.

Next time someone asks you about energy and land use, maybe remind them that the ~35 million acres that currently grow corn for ethanol in the US could produce ~15 PWh per year of electricity from solar photovoltaics. That's ~3.5 times more than *total annual generation from all US power plants*.

The Methane spike in the early 2020’s has been explained in two new studies. A combination of weakened atmospheric removal and increased emissions from warming wetlands, rivers, lakes, and agricultural land are to blame. www.science.org/doi/10.1126/...  www.science.org/doi/10.1126/... #methane

The Trump #climate report attempting to overturn the ruling that greenhouse gases are pollutants was grossly scientifically inaccurate. Turns out it was also illegal. #climatechange www.nytimes.com/2026/01/30/c...

"For Claude Code, about 90% of its code is written by Claude Code itself." No judgement. But where the hell are we headed? fortune.com/2026/01/29/1...

wow, this event looks interesting! www.civitasinstitute.org/events/power...

A past criticism of Variable Renewables Energy (VRE) from wind & solar was that their power was intermittent & thus unreliable. But the drop in battery storage cost has ushered in the age of firmed renewable energy (FRE). Renewables with storage are displacing import and fossil fuels. 🧪🔌💡☀️💨💧🔋

NSF has just put out a call for 'concepts' on how to evolve weather forecasting & computing related parts of NCAR. The word climate *does not appear* in this document, but it does ask for ideas on "Ownership of the NSF NCAR Mesa Lab building for private use" Call for input by March 13....

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/...

Oh wow - this is fascinating. At one point in the emails, they got copilot to review the DOE report for them - and copilot told them they were stretching the truth... library.edf.org/AssetLink/18...

People - don't get ChatGPT to write your job application letters. When you read 100+ of these things in a row - they all sound identical, with generic references to the job ad. You can pretty much guess the prompt they used. The easiest way to stand out is to be your imperfect, brilliant self.

These dynamics are clearly happening - seemingly creating larger oscillations / stupider decisions over time. But even if the stock market resets, there is also cumulative damage to America's international standing which is not reversed when trump steps back from the brink.

These things can be simultaneously true: 1- We can't meaningfully address climate change if the world is held hostage by authoritarians who are actively seeking to undermine international agreements. 2- decarbonisation is a critical part of gaining leverage against those authoritarians

It feels like the necessary response of the civilised world to rising authoritarianism might be defined by this speech, if others follow. Principled, but strategic. Intelligent, but forceful. Multilateral, but not complacent in the role of existing institutions.

If the last decade has taught Europe anything, it should be that reliance on fossil fuel imports is a strategic liability which will be exploited. Climate aside, decarbonisation is security. www.theguardian.com/world/2026/j...

This is the most astonishing graph of what the Trump regime has done to US science. They have destroyed the federal science workforce across the board. The negative impacts on Americans will be felt for generations, and the US might never be the same again. www.nature.com/immersive/d4...

You have to block them immediately. The full nuclear. They are only here to make folks angry, and that can’t happen if we lock them out.

If there's a silver lining to this madness, perhaps it can at least bring wider Europe together with a sense of common identity

Worth noting that the EU’s reluctant tariff concessions to the US, agreed between VdL and Trump at Turnberry, haven’t yet been approved by the European Parliament. There’s no realistic prospect of the US deal going through now.

Called my Congressppl’s office to ask them to oppose any DHS funding that does not rein in ICE. I also asked them to oppose any State or Defense funding that doesn’t include the NATO Unity Preservation Act, which would block the use of funds for military or economic aggression against a NATO ally.

A rare bit of good news from the US. House republicans seem to be pushing back against Trump's huge proposed cuts to science. NSF, NASA, NOAA - all look set to be near flat, or - for DOE - even a slight increase. www.economist.com/united-state...

Preprint out today in ESDD. SRM's biggest risk is us. 'Peak-shaving' is a best-case scenario, with strong governance and international cooperation. We propose a framework for messier geoengineering futures, which look more like, you know, the news. /1 egusphere.copernicus.org/preprints/20...

I had a great time presenting at #AGU25! Grateful for the support of my advisor @kimcobb.bsky.social and amazing @ncar-cgd.bsky.social scientists. NCAR makes my research, and so much other vital climate science, possible.

I was wondering when AMS was going to say something publicly. www.ametsoc.org/ams/about-am...

Good! Colorado Senators Bennet and Hickenlooper objected to moving forward with the minibus spending package, which would have funded 85 to 90% of the federal government through September 2026, because of the Trump regime's plan to dismantle NCAR.

I mean, just look at it. It's a towering physical monument to the persuit of better understanding the science of the Earth. Generations of young climate scientists from across the world have been mentored in its sandstone walls. The symbolism of this attack on free science is unparalleled.

Friends at NCAR, we're with you. @ncar-ucar.bsky.social is a trailblazer in community modelling driven not by idealogy, but by open science. We share all our code, thoughts, ideas. These can't be shut down. We'll fight and find every mechanism to support the ongoing CESM community.

To spare others the difficulty of writing Python🐍 code that simulates a user clicking links in a browser, I am also sharing download bundles of UNFCCC data: industrydecarbonization.com/docs/unfccc....

It's unavoidable that mid-career scientists are (a) (currently) better known by editors and (b) are slammed for time with proposals/bureaucracy. Timely recommendation of relevant younger scientists as reviewers is one key to breaking this deadlock (instead of guiltily letting it sit in your inbox).

And if IPCC AR7 is not released until after the GST in 2028, then they will still be using the 2019 number until 2029, when the budget for 1.5°C would have been exceeded... (unless someone comes up with new bigger budgets)

#cop30 decision's "recalling with concern" that "historical cumulative net carbon dioxide emissions account for at least four fifths of the total carbon budget for a 50% probability of limiting global warming to 1.5C" was true *in 2019*. It's now 94%, best guess. /1 unfccc.int/sites/defaul...

Making a climate model that works well is really, really hard. So hard, in fact, that the people who do make it happen rarely have the time or energy to talk about how hard it is on the internet. So most other people have very little understanding about how hard it is... But boy is it hard #NorESM3

We've been explaining various methods to cook eggs to our kid, establishing a parameter space with rarely sampled areas. It's up to him to now assess why.

This seems dangerous. The whole fact that the working language of LLMs is English isn't an inefficiency - it's a critical safety feature. If we allow native machine learning 'languages' we lose both traceability and our ability to monitor hyper intelligent systems. venturebeat.com/ai/deepseek-...

Dear Google autocorrect: I write "TCRE" about 1000 times more frequently than I write "tyre"and you should know this by now.

Paris-Berlin sleeper: low carbon, 2 years old, constantly full, but currently losing SNCF a few million EUR/yr Intl Jet fuel tax exemptions are 80 years old and cost the EU 22 million EUR/yr for the Paris-Berlin route alone. And you're cutting... the sleeper? www.theguardian.com/travel/2025/...

Let's just be clear on this. 600 billion dollars is enough money to decarbonize the entire US power grid. But somehow our species is spending that money on trying to build a machine which pretty nobody wants, except like the 5 richest guys in the world. www.nrel.gov/analysis/100...

It's weird - but now in Oslo, there's so many EVs that you notice the noise and the smell from individual ICE cars, and you realise how much we've been normalising it for ever. You can smell them half a street away. And inside parking lots are just *quiet*.

Sorry, but disagree with @hausfath.bsky.social here. You open Pandora's box, you ain't closing it again. We've already seen with Paris that well intentioned international agreements do not translate into physical reality and SRM governance is a much harder problem. Zero is the only safe level. /1

WTF??. I've only just appreciated this applies to *existing* visas. The US is effectively expelling its foreign non-naturalized scientists. No scientist can reasonably avoid any travel - for work, and (heaven forbid) to see family. And 100k is beyond the means of pretty much everyone.

Same goes for national labs and non profit research institutes. Pure academic isolationism.

The last few years definitely raise some questions about the lower bounds of ECS BUT.. people, AR7 can't cite bluesky. We need strong updated literature, which fully takes into account the last few years of data - ideally from a few independent groups. Tick tock

I remember only 6 or 7 years ago, trips to Paris were a gridlocked nightmare where cycling was a death wish. It's totally amazing how much they've transformed it into a genuinely nice place for people to walk, cycle, eat outside - just to live. There is no reason this can't happen everywhere.
