30s would have been too much, getting in the way of the talks. The large numbers counting down were enough. Only one person ever dared continue for an extended period beyond the music, and the audience made their displeasure clear!

That’s my timer :) it was 5 seconds of music. Stephanie Waterman timed her talk perfectly to dance to the music 🕺

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!

Agree with all of this, except we had a positive experience with bikes on trains - guess we got lucky … The lack of wind turbines was particularly striking despite a persistent and welcome tailwind!

Nice chance meeting on the ferry from Dublin-Holyhead this morning after both bike touring in Ireland!

@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.

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.

Impressions of Ireland

* Beautiful country
* Lovely people (really, the best)
* Too many cars on narrow lanes going too fast, and not enough of them are EVs
* A few drivers slow down to pass; some even give a whole lane (which is 1.5 m and the law)
* Too many cows
* Could have more vegetarian food
* Well signed cycle ways on roads with 100 km/h speed limit and no shoulder 😬
* Windy, yet not many wind turbines.
* Challenging to take bikes on trains

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.

Hmm … my personal experience is that my highest quality research (I appreciate highly subjective!) has been the hardest to fund. Meanwhile I’ve seen recent calls for large programmes of dubious quality.

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. 🌊 ⛴️ 🧪

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."

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.

Trump's attacks on universities get ever darker, with the shadows reaching our shores

The US has become a hostile and authoritarian state to foreign scientists and is choosing ideology over science.

75% of US scientists who answered Nature poll consider leaving

More than 1,600 readers answered our poll; many said they were looking for jobs in Europe and Canada.
