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.

The worst of both worlds - DOE not withdrawing report AND refusing to respond to public comments on it. But the substantive question is related to how it is used to support (or not) EPA's proposed repeal of the Endangerment Finding - still TBD I guess?

I've been getting requests from reporters about the disbanding of the DOE Climate Working Group. Here are some comments. More to come on my Substack (www.theclimatebrink.com).

This is a fascinating development. Lawyers: Does DOE dissolving the climate report research group and declaring the lawsuits "moot" imply that the report cannot be used as the basis for any future lawmaking? Is there also responsbility for damage from misinformation? www.law.cornell.edu/wex/moot

Our finalised paper on flat10MIP is finally up in GMD! This is the experimental protocol which allows for a simple, emissions-driven evaluation of TCRE, ZEC and climate reversibility in CMIP7. Thanks so much to all who ran these simulations as a proof of concept! gmd.copernicus.org/articles/18/...

Huh... My Norwegian phone carrier blocks war.gov as an unsafe website.

I never thought I would be spending my time explaining the scientific method to one of the most well funded research institutions in the history of humanity, but here we are. But it was so uplifting to see so many brilliant scientists provide context to every point in this thing. You guys rock.

What a situation we're in. ▸He said countries were “destroying themselves” with wind energy and said, “I hope they get back to fossil fuels.” The most powerful country in the world is now punishing other countries for addressing the climate crisis.

Why can't we just provide the DOI of a paper to a journal and then they can format it how they like? Like, I don't know what volume this paper was in because I'm not sitting in front of some shelves in a research library in 1992.

Numerical weather prediction models (ECMWF IFS) still outperform AI weather models in forecasting record-breaking hot and cold extremes and unseen wind extremes Preprint arxiv.org/abs/2508.15724 with Zhongwei Zhang @erichfischer.bsky.social @zscheischlerjak.bsky.social and Sebastian Engelke

This article nails it. It's happened so fast, and we still focus discussions on the risks and promises of a future AI - most of which remain fantastical. In the meantime, we've collectively surrendered our cognitive independence without even questioning it. www.theatlantic.com/technology/a...

I should clarify, for the sake of my nice collaborators and various funding agencies - that I do, in fact, think that simple models are useful.

👏👏 @robinlamboll.bsky.social, this is great. My favourite part is 'GitHub, a normal place to upload recipes'... 😆

Simple climate modelling is just basically asking "shall I reduce your entire field to 1 parameter or 2... or just ignore it completely?"

This is unbelievable. The high temperature at one of Finland’s northernmost weather stations, in the municipality of Sodankylä (Lapland region) within the Arctic Circle at latitude 67.3°N, reached at least 25°C for 26 days in a row. Records date back to 1908.

Going more deeply into this, one of the most bizarre omissions in the whole document is it doesn't mention TCRE, anywhere, in the whole report. The underlying principle which equates cumulative emissions to warming, the foundation of carbon budgeting which underpins the Paris Agreement. Nada. /1

This is great news - summer trial of a direct Oslo-Malmo service was a success, and will become permanent (albeit weekends and holidays) from December. And they seem to be quite serious about longer term plans for direct services to Copenhagen and Hamburg. www.nrk.no/stor-oslo/ny...

Dude has some magic beans for you. “the energy required is going to be a lot for AI systems, but the amount we’re going to get back, even just narrowly for climate [solutions] from these models, it’s going to far outweigh the energy costs.” Here's the thing./1 www.theguardian.com/technology/2...

Big El Niños 🌊 usually come with big 🌎 teleconnections. The one in 2023/24 didn't. Why? Rainfall anomalies in the tropical Pacific were suppressed due to greater warming in Indian and Atlantic Oceans. www.nature.com/articles/s43... Led by Lei Zhang, with @matcollins.bsky.social @cires.colorado.edu

The energy scale of planned AI datacenters is terrifying. This project is 1.8GW, ~20% of Wyoming's electricity generating capacity. The energy partner is all about the CCS, but has no operational capacity yet, for the ~6 million tonnes of CO2/yr it's going to make... apnews.com/article/ai-a...

This is the way.

Good article but I feel this also goes beyond the national angle. The decline in the scientific dominance of the US won't just hurt them, it could delay global scientific progress where other states don't have the drive, resources or concentrated expertise to carry on the momentum. /1

"The AI infrastructure build-out is so gigantic that in the past 6 months, it contributed more to the growth of the U.S. economy than /all of consumer spending/" - @mims.bsky.social My takeway is that The US has gone ALL IN BET OF THE 21st Century on AI, while China has gone all in on green tech

Claim: "Water vapor is a greenhouse gas!" Reality: Yes, and there's more of it in a warmer atmosphere -"CO2 is plant food!" -pretty hard to eat when you're on fire -"Climate has changed before!" -We know, we told you that -"Scientists don't know everything!" - doesn't mean we know *nothing*

Right then... A quick review of the DOE's new 'critical review' of climate science. Whether it's worth a formal community response - I'm still not sure, but here's my first thoughts /thread/

Paris-Copenhagen and Copenhagen-Oslo sleeper services would be totally transformative for Norway's international rail accessibility. Man, I hope these guys pull it off. noxmobility.com/0196fc13-af0...

Aaargh... Contrail management is not a 'silver bullet' for aviation's climate impacts. Reducing instantaneous warming effects from contrails is worth doing - but cashing this in to justify further aviation CO2 emissions is a total scam. www.newscientist.com/article/mg26...

@rosieafisher.bsky.social just referred to my wider set of collaborators as "ZEC bros" and I'm not sure what to do with that.

Thinking about devastating cuts to NSF: US gov-funded science has been the engine upon which most of the tech wealth was generated. But the oligarchs (currently hoarding much of that $) think it’s their own brilliance & not the accident of standing close to the scientific engine that made them rich.

Countries that are able would be stupid not to try to attract top US researchers. But because other countries have a very limited capacity, it means that only the most high-profile researchers who can relocate will be able to continue their careers.

One thing that really bothered me about this discussion was the number of speakers who insisted that the gov attacks on US science are "unprecedented". They're not. Nazi Germany, the Soviet Union, Iran, Turkey & more all purged their academy. Surely learning from that history is essential. #EGU25

Much of the debate we've seen so far has posed Trump's attacks on science as an American problem - but it's not. It's a global problem. The stark reality is that US research underpins much of the world's science - and it's not just money. /1 www.nytimes.com/live/2025/05...
