Son travail de thèse consiste à étudier l'évolution à long terme du pergélisol ❄️ des #montagnes et la réponse au changement climatique, en utilisant des images aériennes historiques. #permafrost #RockGlaciers #Cryosphère #FrenchAlps
La dynamique du #permafrost et les risques naturels sont liés en raison du #changement_climatique qui impactent les régions de montagne.

When peatlands get featured in @AGUbiogeo @AGU_Eos, you know it's time for a deep dive into why these ecosystems are so unique! Stick w/ this thread today to learn @ peat, carbon, what is challenging its resilience, & why peatlands are a global treasure. eos.org/articles/resil…
@AGUbiogeo @AGU_Eos What IS a peatland? Seems simple- they are systems that have accumulated at least 40cm of peat. What's peat? It's dead biomass, mostly plant but also microbial & animal remains. So when enough dead stuff vertically accumulates, we call it a peatland. This is where simple ends....
@AGUbiogeo @AGU_Eos First, peat can accumulate for different reasons. Most scientific studies begin with this: "Peat accumulates where ever plant production exceeds decomposition". I have written this many times! But I now realize it's only partly true, & this is really important for resilience.
