Loss of glaciers faster than expected

This second episode looks at the work of scientists at the Grenoble Institute of Geosciences who are studying the climate change effect on glacier behaviour. In mountainous and polar regions, glaciologists such as Fanny Brun measure the melting glaciers and collect ice samples, sometimes under extreme conditions, as evidence of climate change over time. Laboratory analyses are used to understand the climate change effect on glacier behaviour. Gerhard Krinner, a…

An interview with Jean Jouzel, Director of the Institut Pierre Simon Laplace in Paris, who received the CNRS Gold Medal in 2002 jointly with Claude Lorius. Jean Jouzel develops mathematical models for calculating climate warming as a function of the nature and gas content of the atmosphere. Bubbles of air in ice cores collected in the Antarctic reveal the composition of the atmosphere in past centuries. Scientists thus obtain correlations between greenhouse gases and climate cycles. Jean Jouzel…

Portrait de Valérie Masson-Delmotte, lauréate de la médaille d'argent 2019 du CNRS. Climatologue au Laboratoire des sciences du climat et de l'environnement (DR04), spécialisée dans l'étude des variations climatiques passées, la compréhension du cycle de l'eau et l'évaluation des modèles de climat.

En Islande, l'équipe de muographie de l'Institut des 2 Infinis de Lyon (IP2I - Lyon) installe un détecteur à muons afin d'imager le volcan Snaefellsjökull. Jacques Marteau, physicien des particules lauréat de la médaille de l'innovation du CNRS 2022, présente ce procédé innovant qui permet d'obtenir une image de l'intérieur des structures traversées, comme avec les rayons X en imagerie médicale. La muographie devrait permettre de vérifier l'existence d'un système hydrothermal actif au sein du…

Antarctica is a hostile territory due to its isolation and extreme climatic conditions, but it is also a place of unique opportunities for research and has been a protected area reserved for scientific exploration since the Madrid Protocol was signed in 1991. This film presents the work of four researchers from various fields who went to Antarctica to conduct their research project: studying animal behaviour, observing the Earth's magnetic fields, collecting and analysing micrometeorites and…

Presentation of the polar and Alpine glaciers: area covered, snow and ice states, evolution and movement etc.

In 1963, a scientific base was built in the Kings Bay of Spitsbergen. It ' s the only French base of the whole Arctic. This film recounts the activities of the French scientists on this base through current and stock documents.
