Almost every European plant species is out of equilibrium. Climate change is only part of the story—disturbance greatly shapes where species actually occur. 🚨Our new paper 🌱in @natecoevo.nature.com analysed 3,047 species across >1.1M European vegetation plots. www.nature.com/articles/s41...

Are @ec.europa.eu proposals for #CAP for the period 2028–2034 fit to drive the scale of environmental and climate action Europe now needs? Read our latest briefing to find out 👇
Strengthening environmental ambition in the proposal for the CAP 2028–2034 - IEEP AISBL
This briefing evaluates whether the Commission’s proposals for the Common Agricultural Policy (CAP) for the period 2028–2034 are fit to drive the scale of environmental and climate action Europe now needs. Despite some positive steps, the proposed framework could ultimately undermine environmental ambition if key weaknesses in funding, governance and performance monitoring remain unresolved.

French government about to lead a request to demote UN rapporteur Francesca Albanese (whom they likely assess as not sufficiently comprising her duties, by not letting the government of Israel getting away with the genocide it commits), using fake news 🤮
Manon Aubry@manonaubryfr.bsky.social · 6mo ago✉️ Avec + de 100 députés en Europe, nous soutenons Francesca Albanese, victime d'une cabale du gouvernement 🇫🇷 sur des propos qu'elle n'a pas tenus.
