Well that record didn't stand for long. A new record daily high of 432.69 ppm was reached on 31st March 🏆 That's the first day in human history to exceed 432 ppm.

It's the time of year when atmospheric CO₂ levels approach their annual peak so I just had a look at how they're rising. Three days ago the Mauna Loa Observatory recorded a daily average of 431.95 ppm, which I think is a new daily record. Onwards and upwards 😱 Graphic from gml.noaa.gov/ccgg/trends

It's almost as if someone in control of the funding can't cope with the truth, and definitely doesn't want others to find out about it.

View looking up at the bottom of the large inflatable globe that's been hanging outside the @bas.ac.uk conference theatre for the past week or so. Can anyone spot why this can't be a genuine satellite image mosaic? As someone commented when I pointed this out, maybe it's a vision of the future 😰

NEW: I’ve found an opaque financial vehicle owns a large chunk of the Observer. And neither it or the Guardian will say who it is. Why? Well there is a clue. Which goes by way of Saudi Arabia… 1/ open.substack.com/pub/broligar...

"At this point, Reform isn’t so much an insurgency as it’s a witness protection programme for disgraced Tory ministers and MPs, except nobody has changed their name and they’re still doing interviews." 🤣

The last 11 years have been the hottest years ever recorded. Earth’s energy imbalance has reached its highest than at any time in observed history, with heat reaching deeper into the ocean. This is the Global #StateOfClimate 2025. 📰 Press release: https://bit.ly/4ds4r2V #WorldMetDay

Some climate change facts: 2015–2025 = hottest decade observed 🌊 ~90% of excess heat stored in the oceans Heat gain ≈ 18× global energy use Rate is accelerating, not stabilizing This isn’t just warming; it’s a system moving further out of equilibrium www.theguardian.com/environment/...

The feeling right now of every scientist trying to communicate the seriousness of ongoing global warming and the urgency of reducing emissions. Excerpt from a cartoon by the late Jon Kudelka.

Six years ago today. The early morning view from the @bas.ac.uk Rothera research station on Adelaide Island, #Antarctic Peninsula, shortly before I heard the news that the UK had gone into #lockdown.

For several months, people have been wondering why Reform hasn't declared any crypto donations, despite Nigel Farage saying they'd received some Now @theobserveruk.bsky.social can reveal why...

🧵🧪❄️🌊As today is UN World Day for Glaciers I'm taking the opportunity to post this reminder that the main reason nobody can confidently predict how much sea-level will rise over the rest of this century and beyond is "deep uncertainty in ice sheet processes" (IPPC AR6). #WorldDayOfGlaciers #Sealevel

The postcard I sent home from the historic Port Lockroy base on the #Antarctic Peninsula on 27th January was delivered yesterday. I posted it when we visited the base, which is maintained by @antarcticheritage.bsky.social Heritage Trust, during a voyage on the #tallship #BarkEuropa

A lot of good information here about the environmental issues around building the East West Rail route into Cambridge and the new process for getting approval for it. I have the strong impression that the outcome has already been decided. mwilliamson.substack.com/p/will-the-e...

As many of us working in scientific research keep telling you, our world is hanging by a thread. Today @bas.ac.uk

“Rightwing politicians, junktanks & billionaire press tell us our energy security will be enhanced & our bills fall if we abandon net zero, ditch renewables, reinvest in North Sea gas. These claims are not just a bit wrong. They’re the exact opposite of the truth” www.theguardian.com/commentisfre...

Surely in view of everything we know about how our climate is changing there is nothing surprising about this survey result? Experts warn of ‘dramatic development’ as all but two of Austria’s 96 glaciers have retreated www.independent.co.uk/news/world/e...

Seriously, this is only a little crazier than some of the geoengineering concepts that have been receiving favourable media coverage recently.

I've seen some reports with headlines highlighting the fact this summer's Antarctic sea ice minimum hasn't been as low as those over the past four years, and describing this as a "recovery". Before anyone gets too excited I suggest looking at the longer term trend. Graphic by @zacklabe.com

Accelerating the energy transition away from fossil fuels makes sense on multiple levels. Reducing our dependence on supply from the Middle East is one of them.

RE: https://eupolicy.social/@finnmyrstad/116141082378515849 This is actually brilliant.

As I was saying. Now add Gorton and Denton to Caerphilly. The real story this morning is that this by-election confirms the overwhelming majority of the British electorate reject Reform's manifesto of hate. Sadly, swathes of the media want to tell a different story.

Major threats to our well being from climate change can be avoided, or hugely reduced, by rapid action. Our Nature comment calls for a global risk assessment, effectively communicated to governments, the media and the public, to make clear what is at stake. www.nature.com/articles/d41...

If your priority is stopping Reform you need to know who to vote for to do it. This site has the answer. 👇🏻

It can take science orgs a bit of time after the end of the year to stitch together all the observations of global surface temperature into an annual picture. All 5 of the major datasets are now available, so we’ve put together the latest annual update. #ClimateFacts #ScienceMatters [1/8]

🧪🧵 During my recent voyage to the #Antarctic Peninsula on #BarkEuropa we experienced rain rather than snow on 5 consecutive days, which I'm fairly sure must be unusual in this region. The temperature anomaly map for January from @copernicusecmwf.bsky.social provides an explanation.

🧵 If warming continues to 3°C above pre-industrial we will have crossed a number of tipping points. Droughts in some regions and extreme rainfall in others will result in widespread crop failures and global food shortages. www.theguardian.com/environment/...
