the @australia.theguardian.com published an oped by me today. This heatwave is bad. The bushfires it is enabling are also bad. Climate scientists & meteorologists are incredibly concerned about the next 48 hours. And this is just a taste of what's to come. www.theguardian.com/commentisfre...

⚠️⚠️🔴 Red weather warning issued 🔴⚠️⚠️ Wind across the Isles of Scilly and parts of Cornwall Thursday 16:00 – 23:00 Latest info 👉 bit.ly/WxWarning Stay #WeatherAware ⚠️

This is forecast to result in storm surges ~1 metre on the English Channel and Bristol Channel. Fortunately it is not a spring tide, but the total water levels will be fairly high. There will also be large waves. Please follow local warnings and stay safe.

The USA has pulled out of the UNFCCC. www.theguardian.com/us-news/2026...

There is simply too much news.

Although its very cold at the moment in the UK, 2025 was both the warmest (with a mean temperature of 10.09°C) and sunniest (1648.5 hours) on record. Here is a climate and weather #dataviz summary for the last year. #climatechange #globalwarming.

It's the most magical time of the year — when estimates of last year's global average temperature anomaly come out. Time to dust off my "last year was hot" auto-response.

“it is clear from our weather observations and climate models that human-induced global warming is impacting the UK’s climate” "Since the start of the 21st Century, a new record has been set for UK annual mean temperature no less than six times – in 2002, 2003, 2006, 2014, 2022 and now 2025"

Oh, right. Of course.

Even after the news last week, we are still doing great research here at NCAR. My group has released a new paper, led by John Schreck, on arxiv about an efficient method for generating calibrated AI weather ensembles with reproducible scale specific perturbations. arxiv.org/abs/2512.18815

Great graphics in this Guardian story on climate impacts www.theguardian.com/environment/...

Yes, your chocolate orange IS smaller - and it's because impacts driven by climate change, at home and around the world, are driving up the prices of ingredients: cocoa, sugar and milk in particular. www.theguardian.com/lifeandstyle...

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.

If you’re driving fast at night down an unknown road, turning the headlights off is a really bad idea.

Closing this world-leading climate research centre would be a disaster for the science of climate and our understanding of climate change - which gets more important to everyone, every day. I spent a formative couple of weeks there in 2013, it was welcoming, open, classy, excellent and beautiful.

Exclusive: The Trump administration is moving to dismantle the National Center for Atmospheric Research in Colorado, according to a senior White House official, taking aim at one of the world's leading climate research labs.

America, I’m so sorry you lost Rob Reiner in such a terrible way. What a prince of a man. What a joyous legacy.

i have said this before but if you are actually interested in influencing people beyond a narrow circle of too-online journalists you will be making direct to camera videos on tiktok, instagram and youtube. if you primarily post on text-based social media then you're just dicking around.

It appears that the U.S. Environmental Protection Agency (EPA) has, within the past week, scrubbed a large amount of climate change content from its official website, as well as *removed human-caused warming* from the discussion on its "causes of climate change" page.

Watching my organisation’s “awards for excellence” and remembering that year that “colleague of the year” noms had to go up against a guy that rescued 12 kids from a cave in Thailand lol.

This is absolutely awful. This was one of the best resources for climate indicators data, and my go-to share for help answering public questions. Luckily I captured some of them on my new U.S. climate page a few months ago: zacklabe.com/united-state...

The Google Gemini3 LLM is remarkably excellent at reading weather observations from handwritten logbooks. Example of recovering hourly pressure observations taken in Oxford in December 1883 and January 1884, compared to human-keyed data from relatively nearby sites. Climate data rescue solved?

Why yes, I have spent time this afternoon asking chatGPT to generate images of a cartoon cow farting and burping.

Or for those unfamiliar with units of Denmark-metres, the GRACE satellites have measured that since 2002, Greenland has lost the equivalent of a block of ice 52 km x 100 km x 1 km thick. Approximately 0.25 Wales-km, or 0.6 Australia-metres.

Santa lists are just how we get kids used to the Grind mindset. Have you been good enough? No?! No presents for you kiddo.

Just trying to understand these two news items published within 5 days of each other

There’s an amazing TikTok (wannabe) influencer who is consistently claiming that fossil fuels saved the whales and are vital for improving the lives of women in low-income countries. Comms judo.

Hahahaha

Congratulations to the BBC for finding such an effective way of making sure loads more people listen to the Reith lectures this year.

Where have the greatest humid heat extremes been observed? Where is statistically likely to see unprecedented extremes? New study led by @regclimo.bsky.social investigates:

Well that sounds like it deserves a look.

Saving this for future reference.

Interesting, as a numerate scientist who was dialled in to Covid statistics from the very beginning of the pandemic, I just found myself uncontrollably sobbing upon reading this headline. www.theguardian.com/uk-news/2025...

This Remembrance Sunday I remember my Grandfathers, who both put their lives on the line to fight fascism, and both struggled to cope with the trauma for the rest of their lives.

MAHA. Make the Anthropocene the Holocene Again.

Brilliantly walking the thin line between great and mean parenting.

Alas, every generation needs to learn how to push back against racism and fascism. But in doing that we can also learn how we are better together. Today's Exeter is for Everyone rally 1/2 exeterisforeveryone.com

"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.

The frogs have made it to Exeter.

Hey US science folk, everything seems a bit, er, suboptimal at the minute. Is there anything we can do? How can we help? Can we be useful at all, or is that a vain hope? Feel free to dm etc.

The incredible tragedy for #ArcticScience of NOAA shutting down their #methane monitoring data. 5th May 2025 is the last data we'll ever get. #NCKF25

Deep emissions cuts before mid-century are crucial to limit centuries of sea-level rise, new research has found. Today’s choices could spare future generations up to 0.6m of rise. Read more in our Press Release 👇 www.metoffice.gov.uk/about-us/new...

*Of course* it turns out that that pro-car oped in the FT was by a guy from right-wing lobby group Policy Exchange.

Let’s go back to powering the world with whale blubber.

It’s interesting that these high-inflation foods are also among the most carbon intensive. Natural feedback?
