Great Channel 4 News report on the latest #AMOC monitoring.

Started off ok but then totally lost count.

LLMs playing chess is also rather bizarre....

Climate Scientist Reacts to AI Overlords YouTube video by ClimateAdam

Quite an eye-opening video about the tech bros by the inimitable ClimateAdam. Watch it. youtu.be/py0XpKxAnNU

Is it helping or too early to say? I've never tried it properly (although I reduced sugar nearly to zero and stopped any processed food) for my ME/CFS but heard some find it beneficial.

I'm in SW UK, & it's been a huge change from the driest summer for a very long time, followed by an extremely wet autumn and winter (January broke all records). The v.dry, followed by very wet, plus storms hitting at high tide, has caused damage to roads & rail, & increased coastal cliff erosion.

Yeah, me too and the other duff argument that PR is bad as it would give Farage more seats....

Saw it faintly in Devon, quite a bit of thin cloud

The US is threatening to invade a European country 🇪🇺.

One small way to resist: use European alternatives to US big tech:

Thanks. I've made a start by starting to move from gmail to proton. Very helpful list for identifying other things to switch. The big challenge is getting governments to switch and build EU/UK web/tech/cloud infrastructure (currently 90% US).

Fascinating and a bit puzzling (but good) that quite a signficant chunk of those supporting Trump and opposing Biden must also think climate change is both a problem and man made. Suggests that not all Trump supporters buy into the climate denial that is rife in RW social media & media.

This is the critical problem. By relying on US tech and trade we are almost totally trapped as a vassal of the US. UK plus Europe needs to rapidly start separating itself from the US and plan for the long term without them.

Bloggers claim Met Office fraud! (Let's investigate....) YouTube video by potholer54

Only part 5? 😉

Yeah, UK is in a tough spot. Not sure we can stop him invading Greenland if he really wants it. All we can do is keep trying to talk him out of it, plus maybe put troops on Greenland first with EU allies as a deterrent. Govt doing ok, not sure any Tory govts of past 15 years would do better.

Maybe only give him the prize if he also doesn't invade Greenland. Pretty sure Trump owning it would be bad for climate emissions...

Multi-dataset comparison of global temperatures from 1850-2025, with 2025 values highlighted in a separate panel for each individual dataset. Baseline is a combination of 1850-1900 means.

Most 2025 global temperatures are now out (degrees C above 1850-1900 baseline)

1.41 HadCRUT5
1.44 Berkeley
1.46 JRA-3Q
1.47 Copernicus
1.53 DCENT-I

NOAA and NASA GISS values will be public at 2pm UK time and but based on already public Jan-Nov data they will likely be between 1.3 and 1.4 degC.

I agree but UK + Europe may have no choice but to at least reduce their dependence and start building up its own infrastructure, at least for the most critical services. If the US remains potentially hostile it will be very difficult for UK and Europe for quite a long time though.

Mad, isn't it? I've just started looking to replace as much as I can of US online services/tech as I can with UK/EU, not easy. Europe needs to stick together or risk becoming vassals of either US, China or Russia.

How anyone can justify staying on X/twitter, I do not know.

In a new article over at Carbon Brief, I explore why the past three years – 2023, 2024, and 2025 – have been exceptionally warm. The main culprits turn out to be a combination of El Nino and internal variability, declining aerosols, and a strong solar cycle: www.carbonbrief.org/...

I have a new update to climate model-observation comparisons over at The Climate Brink, covering CMIP3, CMIP5, and CMIP6. Models perform well globally. The latest generation shows too much long-term warming but better reproduces recent trends: www.theclimatebrink....

Love the podcast. Have you thought about having Kate Raworth or Nate Hagens on? Both have interesting things to say about economics and the environment.

Fascinating new paper from Joe Clarke et al., which addresses the question: could the climate-carbon system suffer a self-sustaining runaway feedback? @gsiexeter.bsky.social @ukceh.bsky.social @bolincentre.bsky.social

Sabine has really gone downhill, she doesn't seem to stick to the science now and just berates "activists". The only bit I agree on is that we are slow to act on climate and may not be motivated enough to do so until it's too late. The rest seems clickbait.

Maybe Keir should demand the heads of major US news networks any time they imply Britain is on the brink of civil war or that we live under sharia law. Or does it not work both ways?

Just published, a land-mark paper by Annemarie Eckes-Shephard et al.! It assesses the performance of a new generation of Demography-enabled Dynamic Global Vegetation (D-DGVMs), that attempt to simulate the changing size and age structure of trees in forests.

Congratulations to all involved and particular thanks to @annemarie-es.bsky.social and @tompugh.bsky.social for all your hard work.

Demography, dynamics and data: building confidence for simulating changes in the world's forests Vegetation demographic models (VDMs) are advanced tools for simulating forest responses to climate and land-use changes, and are essential for projecting carbon cycling and large-scale forest manage.....

Our paper is now published! A inter-model evaluation at a variety of forest biomes of nine "state of the art" demographic vegetation models. Well done @annemarie-es.bsky.social and @tompugh.bsky.social for leading this endeavour!
