Glaciers worldwide are shrinking at alarming rates, with dramatic implications for sea-level rise, water availability, biodiversity, and the stability of natural ecosystems.

A new study published in Nature Geoscience by an international team of scientists provides new insights into the natural mechanisms behind century-scale increases in atmospheric carbon dioxide (CO2), known as CO2 jumps. The study, led by Etienne Legrain, paleoclimatologist at the Department of Water and Climate at the Vrije Universiteit Brussel, the Glaciology Laboratory of the Université Libre de Bruxelles and the Environmental Geosciences Institute of Université Grenoble-Alpes provides findings based on high-resolution measurements from Antarctic ice cores.

In early 2024, geophysicist Corentin Caudron plans to travel to Costa Rica to study the activities of the Poás volcano, by measuring sound emissions in the lake that fills its crater. He was to join a 20-strong team and bring back crucial data for volcano monitoring. But nature decided otherwise. An article published in The Conversation.

What exactly happens during and immediately after the impact of a meteorite? That was the question posed by a team of geologists from the research group Archaeology, Environmental Changes & Geo-Chemistry (AMGC) at Vrije Universiteit Brussel. The Chicxulub crater in Mexico is best known because of the extinction of the dinosaurs at the end of the Cretaceous period 66 million years ago.
