ICOS Ecosystem station Fontblanche in France has been featured in Le Monde. A great feature on the people and long-term observations behind our understanding of Mediterranean forests. Congratulations to everyone at Fontblanche involved! 👏

In summer 2026, the hottest summer on record for Western Europe, ICOS stations measured the same conditions they operated through. The stations offer a rare perspective on climate extremes: they both operate through them and measure how the carbon cycle responds. 🔄🌍

I’m attending a hybrid conference where online and in-person attendees type their questions into a meeting platform. It turns out this has the added benefit of stopping those annoying more-of-a-comment-than-a-question monologues and multipart questions. 🥳

The 30 years of measurements in an ICOS station in mainland Denmark show the beech forest has captured an increasing amount of carbon annually, because the growing season lengthens with the changing climate. However, during the drought in 2018, the carbon sink was 25% smaller. #ICOS2026SC

ICOS fixed ocean stations can support our understanding of the carbon cycle in the land-ocean continuum. Signals from river runoff events were detectable at Paloma and Miramare stations in the Gulf of Trieste.

with a neat overview of a decade of atmospheric measurements from ICOS Saclay station near Paris. Highlights the importance of long term data and the benefits of co-location with other #EU_RIs.

"ICOS is a bastion against interest-driven attacks to the science-system," says ICOS's emeritus director @wlkutsch.bsky.social. Consequently, ICOS task is: - Science-based standardisation - Open, free and fair data - Responsible communication and outreach.

Werner Kutsch about strengthening the imapct of ICOS.

Alisa Krasnova from University of Tartu presents 5 years of GHG flux data from a drained peatland forest in Estonia. The forest was a net sink until 2024, but became a source in 2025 after long periods of rain and flooding. Shows drained peatlands are vulnerable to climate variations.

New way to determine ocean carbon sink - using 3 methods based on independent observations - shows the ocean sink is stronger than estimated by current models. It also confirms the stagnated land sink. To be published soon! In #ICOS2026SC by @neillmackay.bsky.social of @exeter.ac.uk.
