My PhD student Selim and I are looking for a motivated Master student to take on a pretty cool challenge: testing the NASA GEDI L4B biomass product across mainland France using a version of the algorithm Selim has been developing in his PhD -building on IGN’s LiDAR HD and NFI data.

Pls share! :)

Le réchauffement climatique n’est pas une « arnaque ». C’est un fait.

Face aux nouvelles déclarations climatosceptiques de Donald Trump, les scientifiques du CNRS réagissent en rappelant les faits.

Multiple models, one forest: a Bayesian perspective.

Led by Nicolas Picard, we combined climate-sensitive forest models to see where they agree - and where they don’t.

A better way to predict European beech’s future in a changing climate.

We show that how you plant tree species (not just which) can significantly boost forest functioning.

High-income groups disproportionately contribute to climate extremes worldwide - Nature Climate Change
While climate injustice is widely recognized, a quantification of how emissions inequality translates into unequal accountability is still lacking. Here researchers examine how affluent groups disproportionately contribute to the increase in mean temperature and the frequency of extreme events.

Bonjour 🙂

On m’a proposé d’écrire un p'tit édito pour la ✉ biannuelle du labo… et disons que je me suis un peu laissé emporter par la 🖋. 😄

Je voulais donc vous partager cette petite réflexion – pas méga structurée, mais j’espère intéressante – sur les obs forestières à très haute résolution.
