In 2023, a record marine heatwave in the North Atlantic, caused by weak winds and a shallow mixed layer, led to severe weather across Europe and beyond. Exacerbated by climate change and reduced ship emissions, this heatwave is a warning for future extreme weather. 🌊🧪

Out today in Nature, our paper on the drivers of the record 2023 summer heating of the North Atlantic. Temperatures warmed to record levels in just a few months. The impacts on climate & ecosystems were severe. A thread on how this work came about and what we found.👇👇🧵 www.nature.com/articles/s41...

Just returned from an extended weekend enjoying fine weather, big skies and amazing wildlife along parts of the north Norfolk coast. Photos here are from a walk this morning along the sea defence dyke between Burnham Overy Staithe and Burnham Deepdale. 1/2

CO₂ at Mauna Loa just reached a monthly average of >430 ppm for the first time. That's possibly higher than in over 3.3 million years. The global RATE of increase is off the chart. It's hard to exaggerate how unprecedented this is!

There are 2 previous historical cases of countries destroying their science and universities, crippling them for decades: Lysenkoism in the USSR and Nazi Germany. The Trump administration will be the 3rd. It's not just budgets but research, institutions, expertise, and training the next generation.

With data for just two more days still to be reported, the daily average CO₂ concentration at the Mauna Loa Observatory has only dipped below 430 ppm on 3 days this month. Therefore, there can now be no doubt that May 2025 will be the first time the monthly average will have exceeded 430 ppm.

BEFORE / AFTER Birch glacier collapse 😮😱 There WAS a glacier here! 🧊 Not only the front, but the entire ice mass has slid down the valley! 🌊 Glad Alain Amherd took two pics with the same angle! 📷🙏

Yesterday's devastating #glacier collapse erasing the Swiss village of Blatten still leaves me speechless... The high mountain areas are adapting to ever increasing temperatures. It's time to wake up! When, if not now? This is not far away but right here... pic: Pomona/A. Amherd

Shocking scenes following the disintegration and collapse of the Birch Glacier. A stark example of the evolving nature of cryospheric hazards under rapid warming and deglaciation in mountain regions. Monitoring and early evacuation prevented a bigger human impact here. www.bbc.com/news/article...

Sound on. The sounds of the South Cambridgeshire countryside this evening. Wonder what it will sound like 10 years from now after the massive developments proposed?

First time cycling to the office today since my Achilles tendon rupture in January. A little slower than I'm used to, but I'll take this for now.

For over 30 years, I've studied past carbon dioxide change and how it impacted climate and life. From rapid increases to the gradual, tectonic shifts over 10s of millions of years. And now, we are here, living in the dramatically different climates of the past. www.theguardian.com/environment/...

Dear @bbcnewsnight.bsky.social @dailymail.co.uk @the-independent.com @thetimes.com can we have more about @greenparty.org.uk MPs and more @libdems.org.uk MPs and less about a party with #5MPs? You need to ween yourself off clickbait.

Despite some misinformation in recent headlines, the long-term trend is still downward for land ice in #Antarctica and #Greenland... My visualization can also be downloaded at zacklabe.com/arctic-sea-i.... It was just updated for data through February 2025.
