Some reflections after returning back from a conference at which I and 20,000 colleagues learned that the Trump administration intends to dismantle #NCAR. This outrage should not happen. deepconvection.substack.com/p/save-ncar

👇

Read this from Ben Santer (very famous climate scientist for those who don’t know) about what NCAR means and what dismantling it will do.

I know many of you who follow me don't work in climate science, but this is the biggest story in climate right now. Breaking up NCAR makes us all less safe and is another act of self-harm that will take decades to recover from.

One of the most random things on YouTube Had to share it for lovers of Liz Truss www.youtube.com/watch?v=ZbB6...

It was a pleasure to meet these guys and discuss the ins and outs, highs and lows, challenges and rewards of communicating science.

Who says art doesn't have anything to contribute to science (or vice versa)? Booked tickets to go see Arcadia next year at the Old Vic. Very excited.

Scientists are expected to be somewhat comprehensible on #r4rtoday but financial folk like CEO of Peel Hunt come on and spout all sort of incomprehensible jargon-nonsense: "backfoot vulnerability starting to wobble", "corporate mood-show", "secondary blocks", "domestic bias" - no me neither.

Brilliant Reith Lecture by Rutger Bregman seems to hit the nail on the head for me. The rise of authoritarian populists, most of the brightest and best going into bs jobs and the question - how is it that small groups of thoughtful committed citizens can change the world for good?

I hosted a great discussion of it all here too:

Overheard in Space, a terrific poem by @michaelrosenyes.bsky.social and read by him as part of the wonderful Hot Poets initiative, has just been released today - find it at www.youtube.com/watch?v=KquX...

I really enjoyed working with the children of St Sidwell's Primary School in Exeter telling new stories about climate change with the international cardboard theatre company Hamishibi as part of the Schools Across the Ocean programme. It was a very inspiring day. news.exeter.ac.uk/faculty-of-h...

"we are far more united and have far more in common with each other than things that divide us" I still believe Jo Cox was right. Despite what happened to her, and what I saw today. Which was a group of people, draped in a flag that is just as much mine as theirs, using it to divide us.

Big turnout at the Exeter is For Everyone rally today that was held to oppose the far-right march through the town centre. Music, singing, chanting and a whole lot of love for diversity.

Well done people of Exeter for turning up and opposing the far right marching on our streets. My Swiss immigrant wife and I met several other non-Brits today who have made their home here and who were also part of the "This is what community looks like" brigade.

Exeter is anti-racist. #ExeterIsForEveryone #StandUpToRacism

When I was in Elgin at the Moray Climate Action Network (CAN) Climate Conference I learnt about this brilliant initiative with hairdressing students to help them talking with their clients about environmental changes called Under The Scissors www.moray.uhi.ac.uk/research/und...

Move over, Alan Turing: meet the working-class hero of Bletchley Park you didn’t see in the movies

Here is a closer look at the record low #Arctic sea ice around Svalbard currently. This coincides with the record warmth as well (check out my earlier post). Earlier last week temperatures in parts of Svalbard were more similar to July than October. Graphic produced by cryo.met.no/en/sea-ice-i...

FACTCHECK: What the Climate Change Act actually means for the UK – and what is a load of old nonsense Really enjoyed putting this together with colleagues, inc learning new things about the fascinating backstory to the Act Feat. OG authors of the Act & more www.carbonbrief.org/factcheck-wh...

Trust me to be giving a talk at the Moray Climate Action Network Climate Conference on the day a severe storm arrives in the area. I'll be talking about the influence of climate change on storms in this part of Scotland as well as my experiences with climate change denial. www.moraycan.org.uk

This is fantastic by @j-amesmarriott.bsky.social Articulates so well our (intentional?) societal regression

Lovely to see the Prince and Princess of Wales visiting my old school today (Churchtown Primary) and the school my cousins went to (Farnborough Road) after the tragic events of last summer. www.bbc.co.uk/news/article...

The people I work with are not stupid people and our climate predictions of 30 years ago of global warming have proved to be accurate. Just saying. www.bbc.co.uk/news/live/cp...

In a moment like this, when tensions are high, part of the job of the president is to remind us of the ties that bind us together.

I'm doing an @arvonfoundation.bsky.social masterclass tomorrow evening (Tuesday) where there'll be some fun writing exercises and I'll talk about some of the tips I've picked up on writing for a general audience and about getting published. Still time to join! www.arvon.org/writing-cour...

I asked my local councillor (elected as Reform) about flags illegally placed on lampposts and painted on roundabouts locally - he replied "Removing [a flag] from any location will always be my absolute lowest priority"

New analysis from @metoffice.gov.uk showing that the record-breaking hot UK summer of 2025 has been made much more likely by human-induced climate change and such a hot summer would be expected about once every 5 years in current climate. www.metoffice.gov.uk/about-us/new...

Final stats after the end of the month, but with the current stats and forecast, a new warmest UK summer is almost certain

Weather in Devon a bit meh today thanks to smoke from fires in the over-heated continent turning what would have been a nice sunny day (like yesterday) into a rather drab murky affair. Another impact of climate change...

Here is a picture of my mum, dad and me (sitting down) and my English teacher, Mr TB Johnson, and his wife, in Bermuda at the last night party of our stay at our beachside hotel during which we played bingo. The story is that my English teacher one day (during 2nd year at secondary school) asked

Letter of the day (in the Times)

Curious that docket number DOE-HQ-2025-0207 - which is the reference number under the instructions as to how to comment on the rather unscientific US climate science report - is not found on the US regulations website. So it's not clear how anyone can comment on it. www.energy.gov/topics/climate

So what makes a climate assessment? In short: not this new Energy Dept report, which rehashes contrarian greatest hits with areas of known uncertainty -- that climate scientists talk about all the time. It's all a little grim. Who needs 721 authors when you have 5?

NEW: i spoke to nine (!) scientists across several disciplines whose work was cited in the new Department of Energy report that downplays the severity of climate change. all of them say their work was misrepresented, cherry picked, and/or lacked context —

A committee consisting of John Christy, Judith Curry, Steven Koonin, Ross McKitrick and Roy Spencer appears to have supplanted @ipcc.bsky.social as the source of climate science assessments for the US Administration. www.energy.gov/topics/climate

I'll be teaching an online masterclass for the @arvonfoundation.bsky.social for academics wishing to write for a general audience. Expect fun writing exercises and some tips from me I've learnt along the way writing my book Hot Air. Everyone welcome, not just academics! www.arvon.org/writing-cour...

My cartoon for this week's @newscientist.com

In a UK newspaper opinion piece today, Matt Ridley (climate confuser) says: "winter nighttime temperatures have risen faster than summer daytime ones" Um, no, not for the UK which the article is about. In fact, the hottest summer days are warming 2x faster than coldest winter nights. Sigh.

we worked so hard on this, nights and weekends, trying our best to do a good job for the American people

My highlight so far dipping in and out of Glastonbury from home is Shaboozey. Brilliant!

I like this selection. From the essay on aunthood and the pandemic-era Auntie Sewing Squad in my new anthology.

On the day the @metoffice.gov.uk publish a new paper showing a rapidly increasing chance of 40°C days in the UK, the GFS produces a forecast ensemble member showing 43°C in a couple of weeks time. This is an extremely unlikely outcome but highlights that these types of temperature are now plausible.
