In this week's Nature we argue there is a pressing need for a global assessment of avoidable climate-change risks. To understand the urgency of emissions reductions, policy makers and citizens need a full analysis of what is at stake including the worst-case scenarios. www.nature.com/articles/d41...

‘HOPE IS THE THING WITH FEATHERS,’ EMILY DICKINSON famously wrote, and that often leads to pictures of doves sitting quietly and looking sweet, but what if hope is an albatross that can soar for years without stopping, or an osprey that can haul a thrashing salmon out of rough waters?

To reiterate: (The fact that he had a gun he never drew is immaterial; the videos show that they attacked him before they knew it; they murdered him after they confiscated it.)

Another day , another caring person murdered #minneapolis #poetry #fury #love

Great to see climate attribution studies featuring as one of the 21 best ideas of the 21st century in today's @newscientist.com . Net zero is another of the best ideas. With me on my Italian summer holidays and Dave Frame and Myles Allen running a climate model on the train to @metoffice.gov.uk

Taking train to Bristol to spend 4 hours being scanned (again) as part of the Biobank project. Feels good to be doing something positive by adding some extra data points to this extraordinary project that is improving healthcare. The power of evidence led scientific research! www.ukbiobank.ac.uk

Atmospheric chemist Susan Solomon was born #OTD in 1956. Solomon, working with colleagues at NOAA, proposed/confirmed the cause of the Antarctic ozone hole, chlorofluorocarbons. She led the Nat'l Ozone Expedition to Antarctica to collect evidence & was the only woman on the team. #WomenInSTEM (1/2)

Just saw this and had to share - PS22 Chorus performing The Cure - goodnight m.youtube.com/watch?v=7KtW...

Ben Santer, an outstanding scientist and historically significant figure in the development of understanding of climate change, is relocating to the UK. Very much looking forward to him visiting the @metoffice.gov.uk to talk about our common research interests.

As a climate scientist, I know heatwaves in Australia will only get worse. We need to start preparing now | Sarah Perkins-Kirkpatrick #Climate

How grotesque the mixture of ambivalence and retreat into useful lies has been to see from news shows , bigots , bots and right wing politicians talking about Renee Nicole Good

Excellent, damning analysis of the video of the killing of Ms Good, from the NYT, including a quick debunking of the “evidence” the President showed other Times reporters last night. www.nytimes.com/video/us/100...

The US has some of the world’s best climate scientists (and more of them than anywhere else) & has contributed disproportionately to understanding the climate system. It’s idiotic for the US to withdraw from the UN Framework Convention on Climate Change & the IPCC but it’s on brand for this regime.

Srsly, @uk.diplo.de , very well played indeed. Your understanding of a UK audience is excellent.

Really enjoying reading the biography of Crick by @matthewcobb.bsky.social. Got me thinking about archives and collecting an archive of the International Detection and Attribution Group (see my book Hot Air). Here are four key members - Wehner, Allen, Hegerl, Tett at an IDAG meeting in the 1990s.

I'm an age when a former time seemed much easier. In the 80s I went to Anfield with my dad with paper tickets bought by post. Today I bought a ticket for FA Cup vs Barnsley but got into a tangle with my NFC pass on my phone that remains unresolved with help desk so as it stands can't use my ticket 😒

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

Style.

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

Climate change is not a con-job. If you want to know more about the evidence for and causes of #ClimateChange, head to our website: royalsociety.org/news-resourc...

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...
