Snow evokes childhood memories, winter, and its sports.A symbol of today’s environmental challenges, it also reveals the vulnerability of the mountains,tested by the effects of climate change. The exhibition ROUGE COMME NEIGE (RED AS SNOW) invites you to explore the many facets of snow — between...
The snows and ice of polar regions and mountain summits are not inert deserts!They harbor a still little-known microscopic biodiversity — including microalgae that, like tiny forests, capture atmospheric CO₂ and transform it into spectacularly pigmented biomass, responsible for the famous “red snows.”But what becomes...

PODCAST Algae blooms, also known as "the blood of glaciers" or "watermelon snow", are present everywhere in mountains and polar circles, but remain poorly understood. A new study reveals that their development depends on the speed...

This phenomenon, familiar to hikers, is often confused with the ochre coloration caused by sands carried by Saharan winds. In fact, it's...
