The term ‘Anthropocene’ was coined in recognition that human activities have ended the relatively stable environment of the Holocene epoch. However, its widespread adoption across the humanities, arts and sciences has led to diverse and sometimes incompatible definitions. In this Perspective, we argue for a stabilized definition of the Anthropocene epoch to help address contemporary environmental challenges, and explore various applications of the Anthropocene across disciplines. The Anthropocene epoch, with a proposed start point in 1952, underscores that human-driven global-scale environmental disruption differs from earlier human impacts of the Holocene, which did not cause such profound destabilization. This clear distinction enables quantitative and qualitative comparisons between the Holocene and Anthropocene epochs, as already utilized, for instance, within the planetary boundaries framework. As the Anthropocene Earth system transformation is systemic, political responses also need be systemic, rather

We are hurtling toward climate chaos. The planet's vital signs are flashing red. The consequences of human-driven alterations of the climate are no longer future threats but are here now. This unfolding emergency stems from failed foresight, political inaction, unsustainable economic systems, and misinformation. Almost every corner of the biosphere is reeling from intensifying heat, storms, floods, droughts, or fires. The window to prevent the worst outcomes is rapidly closing. In early 2025, the World Meteorological Organization reported that 2024 was the hottest year on record (WMO 2025a). This was likely hotter than the peak of the last interglacial, roughly 125,000 years ago (Gulev et al. 2021, Kaufman and McKay 2022). Rising levels of greenhouse gases remain the driving force behind this escalation. These recent developments emphasize the extreme insufficiency of global efforts to reduce greenhouse gas emissions and mark the beginning of a grim new chapter for life on Earth.

Après deux années de veille médiatique, QuotaClimat publie ce jour un rapport international révélant une augmentation alarmante des discours de désinformation climatique dans les médias d’information.

Climate Obstruction Across Europe, coordinated by the Climate Social Science Network (CSSN) and published via Oxford University Press, reveals extensive networks impeding climate action within the region and surrounding states. In Italy and Germany, far-right networks spread misinformation by questioning climate science’s validity, while in Spain and the UK, blame-shifting and deflecting responsibility for climate action are common. European-based fossil fuel industries, like Shell, engage in greenwashing, by framing gas as a ‘bridging technology crucial for the energy transition’, delaying genuine progress.

Simultaneous harvest failures across major crop-producing regions are a threat to global food security. Concurrent weather extremes driven by a strongly meandering jet stream could trigger such events, but so far this has not been quantified. Specifically, the ability of state-of-the art crop and climate models to adequately reproduce such high impact events is a crucial component for estimating risks to global food security. Here we find an increased likelihood of concurrent low yields during summers featuring meandering jets in observations and models. While climate models accurately simulate atmospheric patterns, associated surface weather anomalies and negative effects on crop responses are mostly underestimated in bias-adjusted simulations. Given the identified model biases, future assessments of regional and concurrent crop losses from meandering jet states remain highly uncertain. Our results suggest that model-blind spots for such high-impact but deeply-uncertain hazards have to be anticipated and acc

Vaccination, despite being recognized as one of the most effective primary public health measures, is viewed as unsafe and unnecessary by an increasing number of individuals. Anxiety about vaccines and vaccination programs leading to vaccine hesitancy results from a complex mix of social and political influences, cultural and religious beliefs, the availability of and ability to interpret health and scientific information, and personal and population experiences of health systems and government policies. Vaccine hesitancy is becoming a serious threat to vaccination programs, and was identified as one of the World Health Organization’s top ten global health threats in 2019. The negative impact of anti-vaccination movements is frequently cited as one of the major reasons for rising vaccine hesitancy amongst the general public world-wide. This review discusses the various issues surrounding vaccine hesitancy and the anti-vaccine movement, starting with the definitions of vaccine hesitancy and the anti-vaccine mo

En toute transparence, voici les points clés de ma présentation #climat au séminaire de rentrée gouvernemental

Le sixième rapport d'évaluation (RE6) du Groupe d'experts intergouvernemental sur l'évolution du climat (GIEC) des Nations unies s'inscrit dans une série de rapports destinés à évaluer et synthétiser les informations scientifiques, techniques et socio-économiques relatives au réchauffement climatique. Il conclura le « sixième cycle d’évaluation du climat » effectué par le GIEC1, décidé à sa 41e session (février 2015)2.

Satisfying the increased demand for food is placing pressure on the world’s water, land and soil resources. Agriculture has its part to play in alleviating these pressures and contributing positively to climate and development goals. Sustainable agricultural practices can lead to direct improvements in the state of land, soil and water, and generate ecosystem benefits as well as reduce emissions from land. Accomplishing all these requires accurate information and a major change in how we manage the resources. It also requires complementing efforts from outside the natural resources management domain to maximize synergies and manage trade-offs.

Le gaz et le nucléaire pourraient être considérés comme des investissements « durables » dans la taxonomie européenne. C’est ce que soutient un document confidentiel circulé à la Commission Européenne le 29 octobre. Une information qui, si elle se révélait exacte, porterait un coup de grâce à la construction d’une finance alignée avec les objectifs de lutte contre le réchauffement climatique.

La ou les low-tech, mot à mot basses technologies, ou technologies « appropriées » sont un ensemble de technologies et de logiques visant la durabilité forte, la résilience collective et la transformation culturelle1.

Bien que les acteurs locaux soient les premiers à subir les conséquences des changements climatiques, il ne leur est pas toujours facile de comprendre les phénomènes en cause et de faire des choix d’actions pertinents. En se basant sur des études menées au Canada et en Équateur, cet article montre à quel point il est important de connaître les besoins de formation des différentes communautés et d’adopter des approches et stratégies éducatives appropriées.

Notion ancienne mais plus que jamais d'actualité, la « sobriété » n'a pas une définition figée et regroupe des réalités multiples à travers des démarches de frugalité, simplicité, zéro-gaspillage, efficacité, sobriété énergétique, ou encore de déconsommation. Le dénominateur commun de ces diverses approches est la recherche de modération dans la production et la consommation de produits, de matières, ou d'énergie. Dans son application, indépendamment du vocabulaire employé, la sobriété se développe sur un continuum entre deux grandes approches : une approche institutionnalisée depuis quelques années, centrée sur la recherche d'efficacité et compatible avec la poursuite de la croissance économique grâce au découplage de ses impacts, une approche émergeant dans des mouvements citoyens, centrée sur une transformation plus profonde des pratiques individuelles et des modes de vie. Pour chaque approche, des propositions existent à plusieurs échelles d'organisations socio-économiques et au niveau individuel.
