This is my favorite climate change chart. Japanese monks, aristocrats, and emperors kept meticulous records of cherry blossom festivals for 1,200 years and accidentally built the world's longest climate dataset.

It was such a pleasure to host @projectconcerto.eu @terradt.bsky.social at Barcelona @bsc-cns.bsky.social 🌍🌱🌦️💻

Day 2 of #CONCERTO_GA2026 opened with a presentation by Stefano Materia and @amirpasha.bsky.social from @bsc-cns.bsky.social showcasing the advanced AI applications for land cover and land management projections. This sparked a discussion, reflecting on the challenges for land management in Europe

"In a landmark study, OpenAI researchers reveal that large language models will always produce plausible but false outputs, even with perfect data, due to fundamental statistical and computational limits." www.computerworld.com/article/4059...

Apply to attend the AI for Climate and Weather Forecast training school! APARC & WCRP are hosting AI4Climate from 24–28 Nov 2025 in Dakar, Senegal. If you’re an early career scientist interested in applying AI to climate and weather forecasting, apply by 15 Oct at sites.google.com/view/ai4clim....

Vaccine skeptic is not a thing, in the same way that climate change skeptic is not a thing. They’re science deniers and they’re gonna get a lot of people killed.

"The power of human beings to control and change the environment is growing as our technology grows. At present, we clearly have reached the stage where we are capable to make significant changes in the global climate." -Carl Sagan, 1985

🎉 The ELLIOT project Kick-off Meeting was successfully hosted by CERTH-ITI, in Thessaloniki! 🏛️ 30 partners from 12 countries 🌍 launched this exciting journey to advance open, trustworthy AI and #FoundationModels across Europe. 🤖 Stay tuned for more updates on #AIresearch and #TrustworthyAI! 💡

It was so great to see @projectconcerto.eu at the AI4C workshop! 🎶🌍💻

They want to close the NOAA lab (GML) that brings you this, the most iconic time series in the environmental sciences. gml.noaa.gov/ccgg/trends/

Take note.

Your war machine and greed have left no place in the world untouched. #noIranWar

This morning, the only country to ever use nuclear bombs on cities, alongside the only one with undeclared nukes outside the NPT, dropped the world’s biggest bomb on a state with no nuclear weapons, under the strictest monitoring, and a signatory of the NPT. #noIranWar

📯Calling all AI x Climate researchers! The CMCC Workshop on AI for Carbon (June 30-July 2, Lake Como) just opened their poster submissions! The venue and list of speakers are absolutely stunning 😍 More info: www.cmcc.it/lectures_con... #AI4Climate #CallForPosters @climatechangeai.bsky.social

This weekend, visited #ChrisWareCCCB exhibition! It is super cool! If you are around, highly recommended!

🌍 #EGU25 concludes: a dynamic week of science & collaboration in Vienna with the participation of ➕30 BSC researchers 💡Highlights: ● Patricia Tarín presented her research on "Quantifying the Burden of Air Pollution on Type 2 Diabetes Mellitus in Europe" 📺 www.youtube.com/watch?v=ltJs... @egu.eu

Hey! If you’re around at #EGU today, feel free to stop by my poster—I’d love to have a chat! 📍X5.94 ⏰16-18 @projectconcerto.eu @terradt.bsky.social

Greenhouse gas emissions are still mostly from fossil fuels by the way!! lambwf.github.io/UNEP-Gap-Rep...

In 2024, Europe was the world’s fastest-warming continent. It had its hottest year on record, impacting an estimated 413,000 people. Sea surface temperatures also reached new highs. As our planet heats up, urgent action is more critical than ever.

Great connecting at @ecmwf.int Annual Meeting! Presented my poster on historical land cover & LAI reconstruction in CERISE with AI/ML 🌍🌱. Excellent discussions on how this foundations @projectconcerto.eu & @terradt.bsky.social ! Looking forward to building on this.

Look who is here in @ecmwf.int ancillary data for land surface and earth system modelling workshop! @projectconcerto.eu 🤩

Excited to kick off the workshop on ancillary data for #LandSurface and #EarthSystem modelling! Later today, come by and chat with us about our work on Leaf Area Index #LAI as part of the #CERISE project.

We're on the edge of hitting these "uncompensable" temperatures in a few places, such as the Middle East and India. www.science.org/doi/10.1126/...

Lots of great talks at the @ecmwf.int annual meeting today ; really nice to see @bsc-cns.bsky.social #MN5 pop up in the mix. 🤩🌍🌤️💻

@victorpatrascan.bsky.social Great show tonight in #Barcelona. Looking forward to see back here! Thank you! 🍉🙏🏼❤️

Checked out the Amazonias: The Ancestral Future exhibition at #CCCB — super interesting and beautifully done. Definitely worth a visit if you’re around #BCN #Amazonias

So on March 9, a French scientist, on a visa to attend a conference in Houston, was denied entry to the US and subsequently expelled because his phone had messages decrying scientific policies put forward by the Trump administration: www.lemonde.fr/internationa...

🚀🌍 The #CONCERTO_WorkPackages campaign continues! 📽️🛰️ Work Package 2, develops satellite data-based products to improve land use mapping. 🌿🖥️ It creates a long-term dataset for the leaf area index & a framework to assess land management intensity, enhancing carbon budget insights.

The #CONCERTO_KickOff meeting is wrapped! 👏 For 2 days the partners planned goals to improve carbon cycle models and ways to support the European Green Deal🍃 A strong start, and we’re excited for upcoming meetings to dive deeper into the #science. Stay tuned for more updates! 🌱

Decent people thank Ukraine.

The Greatest Generation only had to fight Nazis. Today, we have to fight Nazis and climate change, and do so without the U.S.

ECMWF has made the land-surface model component of our forecasting system (the IFS) open source. It's called ecLand, and can be found here: github.com/ecmwf-ifs/ec....

Same. Yesterday in my last lecture of the semester, we discussed the importance of defending science and knowledge against the rising threats globally. CO2 will keep rising if we don't do anything about it, and it will keep warming the planet. With or without a website. It's just plain physics...

Roughly 6,000 readers answered our poll, with many declaring that Bluesky was nicer, kinder and less antagonistic to science than X https://go.nature.com/42tH8Ai

💡After a very productive first day of the #CONCERTO_KickOff, we are back for the second half of the meeting. 🌿Yesterday we focused on getting to know each other and our contribution to the project, while today we'll dive into better understanding the various concepts of the project & team tasks.

A paper that understands its responsibility, in a country that knows it when it sees it. Impressive from Die Zeit. Refuses to show the salute, but calls it out for what it so obviously was. Headline: “A Hitler Salute is a Hitler Salute is a Hitler Salute”

The #CONCERTO_KickOff meeting starts today! 🎉 For the next two days, project's partners from across Europe are in Milan to officially launch the project. 🚀 They will aligning on objectives, exploring strategies, and setting the foundation for ambitious goals. 🍃 🤝 Stay tuned for updates!

I’m excited to share Earthly Machine Learning (EML), a podcast created with Google’s NotebookLM—a tool I’ve been using for a while! 🎙️ It delivers quick summaries of ML research in weather, climate, & Earth sciences. 🌍 💻 ✨ Listen on Spotify & Apple Podcasts! #MachineLearning #Climate #weather #AI
