The Paris Agreement

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.

L'Alaska subit de plein fouet le changement climatique. Avec la hausse des températures, le pergélisol se dégrade. Sans cette couche de glace sous terre qui joue le rôle de ciment, les versants de montagnes sont fragilisés. Retrouvez les scientifiques sur le terrain pour étudier avec eux le sol de l'Alaska.

Les océans absorbent 90% de la chaleur dégagée par nos émissions de gaz à effet de serre. Résultat : ils se réchauffent, se dilatent et grignotent les côtes – au rythme de 3,5 mm par an. Comment mesurer ce discret phénomène et donc prévoir son évolution ? À La Rochelle, une équipe du laboratoire LIENSs (CNRS/La Rochelle Université) multiplie les mesures, grâce au marégraphe de l'île d'Aix, au drone Pameli et aux données satellitaires.

In the US State of Arizona, it is not unusual to see rivers that have dried up. Some only flow in specific sections or at certain times of the year. They are known as intermittent rivers. At the CNRS iGlobes laboratory, located within the University of Arizona, researchers study these precarious rivers in the city of Tucson, and in the watershed of Las Cienegas.

Could it be that water contains an almost inexhaustible source of energy, and above all, that it is within everyone's reach? And what if hydrogen would redefine the contours of our future? Faced with global climate change, the quantities of CO2 from industry and transportation that are released into the atmosphere are widely blamed. In order for humanity and the planet to imagine a viable future by 2100, it is urgent to find a sustainable alternative to our fossil fuels. And in this quest for…

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.

How much longer will marine life be able to withstand rising temperatures? Find out more about how scientists are trying to determine the impact of global warming on the physiology and behaviour of the gilthead sea bream.

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…

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…

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?

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?

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…

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…

An endangered population? by Joëlle Robert-Lamblin, anthropologist at the CNRS Module 4: How are local populations adapting to global warming?

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.
