Postdoctoral researcher at @exeter.ac.uk. Climate-carbon interactions in high-latitude ecosystems.

0 mm... Driest July on record at Kew (SW London) since 1800! 💧🔥 1800 also recorded no measurable rainfall, but July 2026 was the hottest month on record, which results in a combination very impressive for the area! 😲 Please note that the local records go back to 1697! ⏱️ 📈 Via @metjam.co.uk

Connaissez-vous les canicules "FLIP"? Désormais, je vais les appeler ainsi pour plus "Fréquentes Longues Intenses & Précoces" en lien avec le carbone anthropique qui s'accumule dans l'atmos. Et parce que je flippe aussi des impacts & désengagement de la puissance publique face aux risques chaleur 1/

If we can get global CO2 emissions to zero, we generally expect the world to stop warming. But why this occurs is fascinating: cooling from falling atmospheric CO2 is more or less perfectly counterbalanced by warming from ocean temperature equilibration.

New research: nitrogen released from thawing permafrost may enhance Arctic vegetation carbon uptake, partially offsetting warming-driven permafrost carbon losses. This highlights the need to better represent carbon–nitrogen permafrost processes in ESMs. 🔗 onlinelibrary.wiley.com/doi/10.1111/...

Nitrogen Release From Permafrost Thaw May Partially Offset Future Soil Carbon Losses

Carbon emissions from thawing permafrost under climate change could significantly amplify global warming. However, permafrost thaw also releases nitrogen, which could fertilise vegetation and increas...

NEW STUDY: Winter downpours are getting heavier in parts of Spain, Portugal and Morocco as the region recovers from a month of relentless storms. Between mid-January and mid-February nine named storms brought torrential rain hurricane force winds causing major damage and disruption. 1/5

🚨 New paper 🚨 We have included key permafrost physical, carbon and nitrogen processes in the IPSL Earth system model. Evaluation shows improved permafrost dynamics and carbon content, paving the way for a more accurate representation of Arctic ecosystems in CMIP7. 🔗 doi.org/10.5194/gmd-...

IPSL-Perm-LandN: improving the IPSL Earth System Model to represent permafrost carbon-nitrogen interactions

Abstract. Permafrost soils have the potential to release large amounts of soil carbon to the atmosphere under climate change. However, in the Sixth Coupled Model Intercomparison Project (CMIP6), only ...

Après plusieurs jours sous les brouillards givrants, la végétation s’est recouverte d’une épaisse couche de givre sur le Nord de l’Indre, vers La Champenoise, ce 5 janvier 2026 matin. Les 1ers rayons du soleil qui ont percé la couche de nuages ont sublimé ce paysage féerique ✨.

Paris-Berlin sleeper: low carbon, 2 years old, constantly full, but currently losing SNCF a few million EUR/yr Intl Jet fuel tax exemptions are 80 years old and cost the EU 22 million EUR/yr for the Paris-Berlin route alone. And you're cutting... the sleeper? www.theguardian.com/travel/2025/...
