What’s worrying here is that the UK government seems absolutely determined to access user private data, no matter the bad press and the consequences. And they’re now willing to do it overtly. Between this and recent moves against encryption in the EU, we’re going to a bad place.

The Radio 4 “In our time” archive is a goldmine and the range is astounding. In the last week or so I’ve listened to the Industrial Revolution (x 2), Typology, Pope Joan and Bacteriophages

Over time the Labour Party might discover that being seen to be overly submissive towards the Trump administration might go down very badly with core voters that it needs

To even allow the appearance of this — Starmer’s No 10 adopting Trumpian media management policies — seems extraordinary to me. Very depressing.

This government needs to grow a spine, a stomach, and a sense of moral purpose right now. Yes, I know that is vanishingly unlikely.

I wrote about this the other day, but I do think it's underappreciated how the lack of interest in government for arguing for a world we might want to live has allowed some of the worst of us to creep in.

sat on a train near some drunk white bloke who, one assumes, was out on the march today and he spent ages physically threatening a black guy but also, for some reason, telling him he was going to rape him? but anyway everything feels great in Britain right now

British NIMBYism is truly a sight to behold.

Good science explains unexpected observations, but great science predicts things only later confirmed from observations. Brilliant article from Nadir Jeevanjee on the fundamental correctness of climate models and the incredible work of Syukuro Manabe. theconversation.com/5-forecasts-...
5 forecasts early climate models got right – the evidence is all around you
From rising global temperatures to the fast-warming Arctic, early climate models predicted the changes half a century ago.

Met Office stats confirm summer 2025 is officially the warmest summer on record for the UK.

The UK’s mean temp of 16.10°C surpasses the previous record of  15.76°C and pushes the summer of 1976 out of the top 5 warmest summers.

The fact that Reform were trying to run a person who had been dead for six months as their Croydon Mayoral candidate is proof if it were needed that they are not a serious party.

It demonstrates abject incompetence and no vetting as well as utter contempt for the electorate.

It is clearly the case that asylum protests were smaller this weekend than the small over-hyped protests on August 8th, and smaller than in the second half of July.

No broadcast outlet has accurately conveyed that + asked why: they have explicitly stated and inferred growing protests

‘The belief that full-time education is the gold standard destination for all young people needs revising. Decent work with training is more beneficial for some.’ @gavin-kelly.bsky.social challenges some orthodoxies

UK regulation of the internet continues to be mind-numbing stupid.

Ministers have spent years passing laws giving the power to fine tech companies billions if they don’t moderate legal content that could harm certain audiences. Now they’re threatening fines of billions if they moderate it ‘wrong’.

Just one chart from the @metoffice.gov.uk State of the UK climate report published today. We get used to focusing on the record highs and how 35C has gone from being rare to routine. But just look at all those summers which never got to 30C even in my lifetime. It’s a different UK now.

We have taken the ensemble version of the Artificial Intelligence Forecasting System (#AIFS) into operations!

It will run side by side with the traditional physics-based Integrated Forecasting System (IFS).
