It’s getting hot!

Certains incendies, comme ceux qui se sont déclarés dans la province de l'Alberta au Canada depuis mai 2023, semblent incontrôlables. Comment anticiper un phénomène aussi variable et imprévisible ? Ce reportage vous emmène en Corse, où des expériences de terrain et des simulations permettent aux scientifiques de mieux comprendre la dynamique des feux de forêt.

For the International Polar Year, the CNRS and the French Polar Institute, Paul-Emile Victor (IPEV) have joined forces to produce podcasts on polar research. A Farewell to the Ice Pack? by Marie-Noëlle Houssais, oceanographer at the CNRS Module 5: Is Man responsible for Global Warming?

SURe est une plateforme cloud prédisant les îlots de chaleur et la sévérité de la COVID-19 à l'échelle du coin de la rue. Construit à partir de modèles théoriques validés sur de nombreuses villes, SURe révolutionne la façon d'accéder aux données environnementales à l'échelle du quartier sans réseaux de capteurs. SURe fournit des prévisions en temps réel, qui varient en fonction de la localisation, de la saisonnalité, de la densité de la population locale et de la texture de la ville.

In this third episode, we find out how to simulate the climate of 2050 and how droughts will be more frequent and last longer. In Lusignan, near Poitiers, agronomy researchers have designed a high-tech mobile greenhouse with drone tracking and 3D images. This may be where the future varieties of European grasslands will germinate...

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.

Cet été, les rues de Paris se transforment en laboratoire pour comprendre et limiter un phénomène redouté par les citadins : l'îlot de chaleur, causé par des matériaux qui emmagasinent l'énergie du soleil la journée et la restituent pendant la nuit. Découvrez les recherches menées dans le cadre du projet "Paname 2022" sur la qualité de l'air et le climat urbain.

This fourth episode is devoted to the sets of equations that represent the physical mechanisms that affect our planet, such as the circulation of water and carbon. How are these models developed? What are they used for? Meet the scientists who are sounding the alarm with the help of these models.

In this fifth episode, we discover the importance of wetlands. They cover only 3% of the world's surface but capture a third of the carbon trapped in the soil. How do they react to changing temperatures? To find out, researchers have installed a range of instruments at a site near Counozouls in the Pyrenees.

Discover the studies behind the statistics of 6th IPCC report and the research work of scientists who aim to gain a better understanding of climate change and its impact. This first episode presents the work carried out by members of the LSCE (Laboratoire des sciences du climat et de l'environnement) at the Traînou site in France. These scientists collect air samples using stratospheric balloons that reach altitudes of over 30 km. The analysis results of these samples are then used…

This sixth episode traces the current development of the Amazon's climate through the involvement of local inhabitants and the analysis of satellite images. The findings are clear, there is more drought in the south, more humidity in the north. With cascading consequences for the global climate...

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…

The scale and speed of the change in climate we are facing today is unprecedented. Heat waves, droughts, floods? We are already experiencing the effects on a daily basis. The effects will increase until at least 2050 and all European regions will be affected. Based on the results of the latest available studies, and in particular on the 6th IPCC report, this animated film produced by scientists in the framework of the European project EUCP presents the changes in Europe's climate expected in…

Pendant longtemps, les discussions sur le changement climatique n ' ont pas pris l ' océan en compte. Quel rôle l ' océan joue-t-il dans le climat et quels sont les impacts du changement climatique sur l ' océan? Trois chercheurs, Sabrina Speich, Gilles Reverdin et Benoît Meyssignac, reviennent sur deux problématiques, le réchauffement et l'élévation du niveau des océans. Les mesures effectuées par des marégraphes, puis des satellites ont démontré que le niveau de la mer est monté…

While nearly 40 billion tonnes of CO₂ are released into the atmosphere by the combustion of fossil fuels, it has now been established that this gas is partly responsible for global warming. An important proportion of this carbon dioxide is captured naturally by the oceans, vegetation and the soil.

An Ecotron is a device that enables scientists to simulate several climate parameters and control them to study miniature versions of given ecosystems. A team in France decided to study Arizona savannahs. Locked in hermetic climate chambers, they analyse different plants from the savannah after accurately calibrating the surrounding light, the irrigation system, and the composition of the atmosphere. Thanks to the collected data, the team will be able to forecast the ecosystem's reaction to any…

For the International Polar Year, the CNRS and the French Polar Institute, Paul-Emile Victor (IPEV) have joined forces to produce podcasts on polar research. A Memory preserved in Ice? by Claude Lorius, glaciologist at the CNRS -Module 4: What climate in the future?

The Tonga mission takes you on board the Atalante, a French oceanographic vessel searching for shallow submarine volcanoes in order to understand and predict the effects of fluid emissions on marine life and the climate. The expedition, led by two researchers, Sophie Bonnet (oceanographer, IRD) and Cécile Guieu (oceanographer, CNRS), is analysing and studying the effects of the addition of trace elements from shallow hydrothermal springs to determine the potential impact on marine productivity…

Antoine Spire interviews Danièle Hauser, an environmental physics researcher and director of the CNRS laboratory LATMOS. She studies the surface of the oceans and its influence on climate.

A video clip produced in conjunction with the publication of Sylvie Joussaume's book "Climat d'hier à demain" at the 2000 Salon du Livre in Paris. Sylvie Joussaume is director of research at the Laboratoire des sciences du climat et de l'environnement (LSCE) in Gif-sur-Yvette. With its accessible style and illustrations which reflect both the current state of the world and the diversity and richness of available climate archives, as well as the most recent results from a rapidly…

Can human development continue at this pace without causing a loss of biodiversity? A group of researchers at the French Institute of Pondicherry believes so. By studying the impact of human activities on a biological hotspot in the South of India, they hope to find the key to a harmonious coexistence between humans and wildlife.
