Hello from Cambridge!

We've just finished our Climate Modelling Summer School. It is an exciting two-week programme of lectures and practical work on climate models.

Thank you to everyone who came along to learn and network with our experts and with like-minded peers!

My impression of Ireland after cycling around for a few days is that it’s a beautiful country with really lovely people. It’s too bad about the smell of cow poop and car exhaust.

Also, @hannahdaly.ie and her Dad are awesome.

@dmarshallocean.bsky.social is a professor of climate physics at @ox.ac.uk. He studies how things that happen on small scales (turbulence and eddies) affect the large scale (ocean circulation). In our parlance, he studies geophysical fluid dynamics.

A new editorial by me on the global implications of Trump's war on science - apart from the devastating cuts to global health, we must urgently build a more distributed science infrastructure.

And remember, GFDL is whee Suki Manabe did his Nobel-prize winning work establishing the physics of CO2-induced global warming. It is a gem in the crown of US federal laboratories, and now it is about to be irretrievably tossed on the trash-heap.

Excellent post by @dinahvp.bsky.social‬ on the plan to devastate NOAA research, with quotes from @franklinjamesl.bsky.social @wxmanms1.bsky.social. "Only a small fraction of NOAA Research would remain and be transferred to the NWS, including portions of the weather, tornado and technology research."

I can confidently say that I would not still be doing physical oceanography without MPOWIR. The termination of MPOWIR's NSF grant is soul-crushing to me. Let's celebrate the success of this 20 year program and get to work continuing its legacy. 🌊 ⛴️ 🧪

For years conservatives and some liberals complained incessantly about ‘cancel culture’ and the lack of ‘free speech’ on campuses. None of that stuff comes even close to what the right is now doing in power, in terms of the open bullying and pressuring of colleges and censoring of curricula.

A chilling thought:

"So if the aloof trustees of Harvard, Princeton, Yale et al think that their august institutions lie beyond his reach, perhaps they should understand that Trump looks on them much as Henry VIII looked on the rich monasteries of his heyday."

We polled Nature readers to ask if they were thinking of leaving the US for jobs abroad. Three-quarters of them (who said they were US-based scientists) said yes. 🧪

Colleagues are cancelling their US work trips. I worry that international colleagues in the US are at risk if they collaborate with us on certain topics.

I've written a new post about the increasing danger of being a foreign scientist in the US.

A friend included this anti-acknowledgement section on her PhD thesis. She also added the proposition: “Systematic bullying and undermining of girls and women in STEM starts early on and is the reason why they do not stay in science and related fields.”

I have been receiving the sad news about massive NOAA firing.

I cannot explain how important NOAA is for science globally. The data and model outputs generated by NOAA globally allow researchers from countries that don’t have the funding or capability to develop those to do their own science. 🌊🧵
