Citing "low enrollment" is always such a cop-out.

a heavily armed paramilitary force with legal immunity is occupying a city and going door to door kidnapping non-white adults and children in furtherance of an explicitly white nationalist political project

So, if you ever wondered why people who understand surveillance are salty about video cameras on doorbells... It's only a matter of time before they get co-opted into mass surveillance. And if the regime you live under changes that's you spying on your neighbours.

New paper out in JAMES (Jan 2026): “ClimaLand: A Land Surface Model Designed to Enable Data-Driven Parameterizations” (Deck, Braghiere et al.). I’m excited to be a co-lead on this CliMA land-model milestone. doi.org/10.1029/2025...

NCAR is quite literally our global mothership. Everyone who works in climate and weather has passed through its doors and benefited from its incredible resources. Dismantling NCAR is like taking a sledgehammer to the keystone holding up our scientific understanding of the planet. Unbelievable.

I'm deeply concerned about the wellbeing of prisoners who were involved in Palestine Action protests, and are currently on hunger strike. Some have not eaten for six weeks. A number have been hospitalised. They are all being held on remand - without trial or conviction.

Our new paper, "Learning enhanced ensemble filters", is out in the Journal of Computational Physics! Led by Bohan Chen and co-authored by Edoardo Calvello, Ricardo Baptista, Andrew Stuart, and myself. doi.org/10.1016/j.jc...

If I were deliberately trying to cause vulnerable refugees as much distress as possible, this is how I would do it. Constantly shifting the ground underneath them, never allowing them a moment of certainty and stability. This is barbarism.

This is utterly foul. People recognised as refugees will never able to settle and find the long-term security they need to recover, always at risk of being returned if they can’t prove they still *really* deserve to be here. A life lived in permanent limbo. www.bbc.co.uk/news/article...

In this new preprint with Jochen Bröcker, we define a generalisation of the signal-to-noise ratio for probabilistic forecasts using proper scoring rules. (1/3) arxiv.org/abs/2510.26809

Solidarity with the Jewish community, especially in Manchester. The murder of two people at worship on the holiest day of the Jewish year is beyond reprehensible.

the UK's new anti-trans rules are indefensible & will make global fascism stronger my latest with @liberalcurrents.com www.liberalcurrents.com/britains-bat...

I’ve been frustrated to see so much of the ongoing story about asylum seekers and the protests against them covered without hearing from those seeking asylum and now being met with hostility and hatred I set out to speak to those directly affected to find out about the impact this is having 👇

As the mother of a young trans person, Alice, who took her life in 2022 aged just 20, and as an ex-NHS doctor, I am struggling to find the words to express my dismay and sadness at this story. Whatever happened to do no harm? 🧵

Deliberately starving people and shooting them when they seek aid is an industrial and systemic approach to mass murder. www.washingtonpost.com/world/2025/0...

In #Gaza, people are starving. Families are going without substantial meals for days. Prices have increased by over 4000%. The Israeli Authorities have banned UNRWA from bringing food into Gaza for over 4 months. This is a manmade and politically motivated starvation of a people. Lift the siege.

Tony is a well-respected colleague, a KC and a former legal advisor to the EHRC. Having spoken to constituents and University of Reading students who are concerned about the impact of this guidance, I'm glad to have signed Tony's letter.

Plans to proscribe Palestine Action signal an alarming escalation of the UK govt’s repression of our democratic rights. Branding the group a ‘terrorist organisation’ would render support for the group and its nonviolent tactics a criminal offence, with penalties of up to 14 years’ imprisonment.

Cutting lines or even whole departments is the frontal assault on higher ed, but another low key war of attrition is the slow accumulation of grinding, meaningless additional tasks concerning syllabus templates, learning outcomes, institutional pablum, and ever more intricate evaluation hoops.

To mark VE day, I am posting an old folder of anti-fascist posters from the Spanish Civil War. I originally started collecting these to try and choose an image for my book cover, and kept going because they're objectively awesome. Lost many in the last laptop migration, but the best remain...

The Israeli authorities have illegally banned all aid and goods into Gaza for two months. This constitutes a genocidal act, a blatant form of unlawful collective punishment, and the war crime of using starvation of civilians as a method of warfare.

People might think that whatever destruction is done to science in the US, we can undo in 4 years with a Democratic president and Congress. The problem is that many areas require specialized knowledge and skills built up over years, and once that's lost, it's hard to get back.

As the egregious imprisonment of Mahmoud Khalil is in the news, here is a good article about the broader context of the repression of the Palestine solidarity movement. Many universities are directly, and shamefully, responsible.

This is the product of non-stop demonisation and propaganda over years. Social hostility, barriers to care, and structural discrimination all do harm and kill. The commentariat and political class are complicit in our monstering through their performative hatred, rhetoric, and disinformation.

Entropy is one of those formulas that many of us learn, swallow whole, and even use regularly without really understanding. (E.g., where does that “log” come from? Are there other possible formulas?) Yet there's an intuitive & almost inevitable way to arrive at this expression.

That Daniel Penny and Daniel Perry and Kyle Rittenhouse and George Zimmerman are all walking around free in the most carceral nation in the world is something that demands a reckoning.

Students should study the humanities not because it makes them better workers but because it rips you open and breaks your brain and changes everything you thought you knew. I *promise* you this. I *promise* it has this ability, no matter how smart you think you are. I have seen it countless times.
