À la fin du mois de juin 2021, une vague de chaleur historique a touché le nord-ouest du Pacifique (PNW) en Amérique du Nord, entraînant des températures extrêmes (50 degrés ont été atteints dans la ville de Lytton), des incendies de forêt, une surmortalité, une perturbation des réseaux électriques et même un impact sur les écosystèmes marins.

With a view to understanding the dynamics of ancient trade and agrobiodiversity, archaeobotanical remains provide a means of tracing the trajectories of certain agricultural commodities.

Ongoing ocean acidification is known to be a major threat to tropical coral reefs. To date, only few studies have evaluated the impacts of natural long-term exposure to low-pH seawater on the chemical regulation and growth of reef-building corals.

Dans cette étude, la diversité des structures spatiales de l’oscillation australe-El Niño (en anglais, El Niño-Southern Oscillation, ENSO) est étudiée sous l’angle de régimes récurrents.

La quinzaine des Jeux Olympique de Paris en 2024 aura lieu du 26 juillet au 11 août, c’est-à-dire à l’apogée de la température en France.

Acqua Alta events in Venice, notably the catastrophic ones in 1966, 2008, 2018, and 2019, have inflicted substantial harm on the city's cultural and economic heritage, including the iconic St. Mark's Basilica, historic shops, and beloved businesses like Caffè Florian.

IUGG, Berlin, 2023 The IUGG Gold Medal is bestowed on Valerie Masson-Delmotte (Laboratoire des sciences du climat et de l'environnement – LSCE, France) for „her leading role in deep ice core climate-record projects, unravelling isotope deposition on polar snow, and for her outstanding contributions to increasing society’s awareness of climate change".

We present an age model for the 651 m deep ice core from Skytrain Ice Rise, situated inland of the Ronne Ice Shelf, Antarctica. The top 2000 years have previously been dated using age markers interpolated through annual layer counting.

by Nathaelle Bouttes During the last deglaciation, the climate evolves from a cold state at the Last Glacial Maximum (LGM) at 21 ka (thousand years ago) with large ice sheets to the warm Holocene at  9 ka with reduced ice sheets.

Les vagues de chaleur font partie des évènements climatiques extrêmes les plus impactant dans le monde et en Europe, notamment du fait de leur augmentation en fréquence et intensité avec le changement climatique d’origine humaine.

Tensions on water is now widely recognized as both a threat and a challenge to human well-being. Although acting on enhancing water availability to some users has been the main option up to now in many situations, attention is more and more given to reducing the demand.

Available at www.climameter.org , Climameter offers a dynamic approach to contextualize and analyze weather extremes within a climate context.

Des chercheurs du Laboratoire des Sciences du Climat et de l'Environnement (CNRS, CEA, UVSQ) et de l'Université d'Uppsala en Suède ont étudié les propriétés d'une méthode populaire d'estimation de la dimension de l'attracteur.

With climate projections threatening the future survival of stony corals and their dominance as tropical reef builders, it is critical to understand the adaptive capacity of corals to ongoing climate change.

by Delphine Tardif   The Asian monsoons are triggered by complex interactions between the atmosphere, Asian and African orography, and the surrounding oceans, resulting in highly seasonal climate and specific regional features.

by Gilles Ramstein Paper: https://www.nature.com/articles/s41561-023-01153-y   As the recently released synthesis of the 6th IPCC Assessment Report shows, sea level rise is already underway.

Les changements des situations météorologiques renforcent les impacts des vagues de chaleurs et tempêtes  en France et en Europe Une nouvelle étude réalisée par des chercheurs de l’IPSL et de l’université d’Uppsala publiée dans PNAS révèle que les changements de situations météorologiques en Europe ont un impact majeur sur le climat de surface, exacerbant les effets du changement climatique.

Going Beyond Models: A Statistical Method for Predicting the Madden Julian Oscillation The Madden Julian Oscillation (MJO) is the major source of fluctuation in tropical weather on weekly to monthly timescales [1].

Le Changement Climatique: cause majeure de la sécheresse 2022 en Europe de l'Ouest Les chercheurs de l’IPSL et de l'Université de Bologne démontrent le lien entre la sécheresse en Europe en 2022 et le changement climatique dû à l'homme.

Soil carbon dynamics is strongly controlled by depth globally, with increasingly slow dynamics found at depth. The mechanistic basis remains however controversial, limiting our ability to predict carbon cycle-climate feedbacks.

Few studies have focused on Arenosols with regard to soil carbon dynamics despite the fact that they represent 7% of the world’s soils and are present in key areas where food security is a major issue (e.g., in Sahelian regions).

Ice core and marine archives provide detailed quantitative records of last glacial climate changes, whereas comparable terrestrial records from the mid-latitudes remain scarce.

When could compound events emerge in the future? Separating changes in univariate and dependence properties by Bastien François   High-impact climate events such as floods or wildfires often result from interactions between several climate phenomena, also referred to as “compound events” [1].

Changes in temperature–precipitation correlations over Europe:  Are climate models reliable? by Mathieu Vrac, Soulivanh Thao, Pascal Yiou Inter-variable correlations (e.g.

Should Multivariate Bias Corrections of Climate Simulations Account for Changes of Rank Correlation Over Time? by M. Vrac, S. Thao, P.

Changes in the climate dynamics have already modified characteristics and impacts of storms in France: the case  study of storm Alex 2020 by Mireia Ginesta Extratropical cyclones play a key role in modulating the precipitation and wind in mid-latitudes and can be responsible for extreme wet and windy events.

Can we attribute the intense precipitation event in the Brisbane region in February 2022 to climate change? Camille Cadiou, Robin Noyelle, Nemo Malhomme & Davide Faranda   From the last week of February to mid-March 2022, the eastern coast of Australia faced an episode of intense rainfall.

A weather ensemble forecasting tool based on statistical and probabilistic methods Ensemble weather forecasts can help to anticipate the risks and probabilities of extreme weather events. Nevertheless, weather forecasting is a complex task due to the chaotic behavior of the atmosphere [1].
