L’ironie peut être une technique de communication efficace pour esquiver les critiques ou ridiculiser un adversaire.

Comment expliquer la persistance de la critique écologique face aux tentatives de compromis du capitalisme, sous la forme du développement durable ou de la responsabilité sociétale des entreprises (RSE) ?

Regional Resilience and Vulnerability to Global Catastrophic Risk

Emerging climate extremes should draw public attention to human-caused climate change. We expect unusual sea surface temperature (SST) and global warming the rest of this year to make 2026 hotter than 2024, despite 2024 being a peak El Nino year, while 2026 is only the lead-in year of an emerging El Nino. Beware the “surprise” record high being blamed on an extreme El Nino on top of global warming otherwise consistent with IPCC estimates. Instead, record warmth provides additional evidence of high climate sensitivity and increased net climate forcing in the past decade. These two factors are driving an unusual increase in global SSTs with major consequences. If you bear with our discussion to the end, you will find some possible good news.

Imagine being told that your children cannot play outside because the grass and soil in your local area is so polluted that it endangers their health. You are not allowed to eat the eggs from the chickens in your garden because eating them could diminish your immune system and/or lead to certain types of cancer. No, this is not the plot of a dystopian novel these are very real consequences for people living in places that are severely polluted by PFAS. Also known as forever chemicals.

Journaliste, essayiste et conférencier, Laurent Testot explore depuis de nombreuses années les grandes dynamiques de l’histoire humaine à travers une approche parfois nommée “Histoire Globale”, insistant sur la transdisciplinarité et profondément ancrée dans les enjeux environnementaux. Auteur notamment des livres Cataclysme, Les forêts, Homo canis, El Niño, Vortex et Notre empreinte sur Terre, il propose une lecture des basculements de civilisation qui replace les facteurs climatiques, biologiques et géographiques au cœur du récit historique. Dans cet épisode de L’Heure du bilan : Faire face, il revient sur son parcours, sa manière de construire ses analyses à partir de plusieurs disciplines, et sur ce que l’histoire globale peut nous apprendre à l’heure des crises écologiques. Un échange dense, lucide mais accessible, qui invite à relire le passé pour mieux comprendre les impasses du présent et, peut-être, mieux "faire face" à l'avenir. Ouvrages • Cataclysmes. Une histoire environnementale de l’humanité

The Prairieland case is about more than eight defendants. It is about the dangerous precedent being built around protest, political identity, and dissent.

Food security (FS) remains a pressing issue at the global scale. Current literature about FS points to a plethora of causes of food insecurity, among which climate change and the loss of biodiversity are critical to all facets of food security. Building on this notion, we advocate for a comprehensive understanding of drivers of food security, thus contributing by examining climate change and biodiversity as drivers of food security. The interest in this subject stems not only from the scientific community, but also from practitioners and policymakers. However, holistic encapsulation of the relevant literature addressing this subject is currently lacking. This review systematically analyses and categorises the drivers of FS induced by climate change and biodiversity. Following the Systematic Literature Review approach, 342 peer-reviewed studies were selected and synthesised. Our findings identified 11 categories of climate change drivers and 9 categories of biodiversity drivers of FS. These drivers were found

Et si le monde fossile était plus fragile qu’on ne le pensait ? Et si le début de son repli précipitait son effondrement chaotique ?

Ce mercredi 17 juin, les eurodéputé·es devraient approuver un texte facilitant la commercialisation d’une nouvelle génération d’OGM (NTG). Comment expliquer que, malgré la masse d’associations opposées à ce texte, quasiment aucune concession en faveur du principe de précaution n’ait été obtenue ? Interview.

Projections of near-term climate change are a potential research tool. However, for that tool to be most useful, the physical basis for a prediction must be made clear. The basis for our projection of record 2026 global temperature is high climate sensitivity, with its implication that aerosol cooling was still increasing during the period 1970-2005. One consequence, global sea surface warming, already has important effects. Causes of climate change must be understood for policy purposes.

How Cynicism Became the New Psychological Performance

Y a-t-il un lien entre le plastique et les ouragans Sandy et Katrina, aux États-Unis, la fonte des glaciers dans l’Antarctique, les vagues de chaleur pendant l’été, l’érosion du littoral en Australie — et quantité d’autres catastrophes naturelles qui s’abattent sur nous avec une fréquence accrue ? Nous incriminons le changement climatique. Mais l’impact des déchets plastiques et de l’industrie du plastique sur le changement climatique est souvent méconnu ou, pire, pris à la légère.

Periodically posting commentary on climate science and policy.

We can’t know how long the war in the Middle East will last. Nor can we know who will “win” it, and in which terms. What we know is that the destruction already wreaked on things and people is immense, and it keeps escalating. The longer the war, the bleaker their perspectives in a region already plagued by all sorts of problems, including drought, soil degradation, ecosystem damage, scarce agricultural resources, declining fertility rates, and more.

Energie-onafhankelijkheid is noodzakelijk, willen we niet langer de speelbal van buitenlandse dictators zijn.

Le philosophe de l'environnement Rupert Read dit à Ella Whelan la panéliste Moral Maze pourquoi nous ne pourrons peut-être plus profiter du même niveau de vie pour le bien de la planète et des générations futures.

There is mounting experimental evidence that lifetime exposure to increasing atmospheric CO2 levels can negatively impact the normal physiology of organisms. Directly assessing this in humans is very difficult. We analysed serum bicarbonate (HCO3−), calcium (Ca) and phosphorus (P) from 1999 to 2020 as indirect proxies for atmospheric CO2 exposure. Over this period, average bicarbonate levels in this population show an increasing trend which parallels rising atmospheric CO2 concentrations. Both. If these trends continue, blood bicarbonate values could be at the limit of the accepted healthy range in half a century, and Ca and P will be at the limit of their healthy ranges by the end of this century. This has the potential to cause a range of adverse health effects.

Science-based policies could successfully limit human-caused climate change, but when political parties are allowed to accept money from special interests, policies are distorted to the point of being ineffective. This is a solvable problem, but to clarify the situation and the needed actions, we need to first marshal the evidence. The draft Prologue of Sophie’s Planet is intended to help coherently organize the evidence. Here is Part III of V, with the final two paragraphs of Part II.

Three major Defence Agencies are quietly admitting what most still refuse to face: climate breakdown is coming for our food, and the cracks are already spreading. While the wealthy cling to logistics and illusion, the real defence strategy is soil and local growers who refuse to let their communities starve.
