Les premières mesures jamais effectuées sous la langue glacée du glacier Thwaites, en Antarctique, ont révélé un flux d’eau chaude jusqu’alors sous-estimé. Cet afflux de chaleur se mélange à d’autres eaux sous le glacier et empiète sur plusieurs « points d’ancrage » critiques, selon les chercheurs, les fragilisant de toutes parts. Si

L’énorme iceberg mesure environ 1 270 km2 et fait près de 150 mètres d’épaisseur, selon le British Antarctic Survey. Il s’est détaché en quelques heures ce 26 février. Un signal de plus de la fonte accélérée des glaces aggravant le risque de montée des eaux. Les scientifiques du British Antarctic

A study published on June 28th in the journal Nature Climate Change warns that over the last 30 years, the temperature at the South Pole has risen three times faster than the global average. An unexpected situation that worries scientists. Indeed, the increase in temperatures in Antarctica could accelerate the rise of the South Pole.

The disaster will not be for thirty or fifty years from now. It won't be in a century. No, it's for 2030, which is tomorrow. A shocking study has just been published in Nature, by Australian researchers who have been analysing for several years a geological period of intense upheaval, the

In the southwest corner of the Antarctic continent, there is a river of ice known as "the world's most dangerous glacier". On Monday, American and British scientists officially launched a venture to study the Thwaites Glacier. Their goal: to determine whether it is heading towards a catastrophic collapse in a

By sounding the alarm about the climate, scientists can make some of us think of the fable of the boy and the wolf. Yet studies are multiplying and repeating themselves: all the scenarios lead to a worsening that is unfolding before our very eyes. One last

Storing samples of glaciers in Antarctica: the idea may seem preposterous. Yet this is the objective of a team of researchers who will be going to Mont-Blanc in August to take samples of ice threatened by global warming. "It's not for the pleasure of keeping a few ice cubes.
