Les projets de croissance des aéroports européens, dont Brussels Airport et Brussels South Charleroi Airport (BSCA), sont incompatibles avec les objectifs climatiques européens, estime une étude de l'ONG Transport & Environment (T&E).

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

Chronic exposure to pesticide mixtures through diet is common, yet their combined metabolic effects and interactions with dietary factors remain unclear. We identified four pesticides prevalent in human exposure (imazalil, thiabendazole, boscalid, lambda-cyhalothrin) and assessed their combined impacts on hepatic metabolism and metabolic homeostasis using human liver cells and male mice fed standard chow or western diets. We found that the pesticide mixture induced metabolic perturbations in human hepatocytes. In addition, the pesticide mixture altered hepatic gene expression in chow-fed mice and exacerbated western diet-induced glucose intolerance, fasting hyperglycemia, and insulin resistance without affecting body weight or liver steatosis. These findings reveal that dietary context influences the metabolic consequences of pesticide mixtures, highlighting the need to consider nutritional status when evaluating environmental contaminant risks. Our results suggest that pesticide mixtures at reference doses m

Historically, the decarbonisation of aviation has lagged behind other modes of transport. However, the technology and policy base for change is finally taking off in Europe, and the region has a real chance to lead. But Europe needs to step on the accelerator, not the brake to maintain its global leadership for a clean transition for the sector.

Global biodiversity loss, ecosystem collapse and national security: a national security assessment

Global energy and materials are essential to the functioning of the economy and have significant implications for macroeconomics and the environment. At the same time, the world is not on track to meet Paris Agreement goals. This paper documents two stylized facts that connect these observations. First, the world economy is characterized by large embedded emissions and materials: different energies and materials are deeply entwined and interdependent. This has historically led to additive – rather than substitution – dynamics in energy and materials on a global scale. Second, historically there has been a strong positive correlation between efficiency in resource use and total resource use at a global scale. We synthesize these observations by introducing the Generalized Jevons Paradox (GJP). We argue that the GJP reflects the direct and indirect energy/material demand effects of long-term energy and material interdependencies, themselves shaped by market and geoeconomic power, trade arrangements, and financi

Le riz nourrit plus de la moitié de l’humanité depuis 9 000 ans. Mais selon une étude publiée dans Communications Earth & Environment, le réchauffement climatique progresse désormais 5 000 fois plus vite que la capacité d’adaptation de cette plante. Les régions rizicoles atteignent des températures jamais enregistrées dans toute l’histoire de cette culture — et le milliard de personnes qui en dépendent directement commence à manquer de temps.

The Green Scare created precedents that today reach far beyond radical environmentalism, and threaten anyone willing to engage in direct action.

Environmental defenders across Europe, South Caucasus and Central Asia are increasingly facing legal pressure, intimidation and attempts to restrict their work. Non-governmental organisations warn about a steady rise in SLAPP lawsuits (1), defamation cases, claims for compensation for alleged damages and other tactics intended to discourage public scrutiny of industrial, mining and development projects with a negative impact on environment. Civic oversight is becoming more difficult, especially for those who challenge powerful economic or political interests.

Yet, as the climate crisis worsens, the civic space for climate protests is shrinking. Instead of focusing on meeting their commitments to reduce climate change, governments are threatening environmental protectors—from Indigenous communities defending their ancestral lands to young activists protesting the expansion of fossil fuels—with intimidation, legal harassment, and at times deadly violence. New forms of attacks are emerging, like the use of counterterrorism laws against climate activists, who are vilified in public and political discourse. And governments have been ratcheting-up their repression of such protests.
