Satellites, ceinture de radars d’alerte avancée, destroyers… Posséder le territoire autonome danois n’est pas indispensable pour les Etats-Unis, qui bénéficient déjà d’un large déploiement défensif à travers le monde.
Les territoires ruraux sont de véritables laboratoires de la transition où l’on expérimente de nouvelles manières de vivre ensemble, de produire et d’agir pour le bien commun.
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.
22 of the planet’s 34 vital signs are at record levels, with many of them continuing to trend sharply in the wrong direction. This is the message of the sixth issue of the annual “State of the climate” report. The report was prepared by an international coalition with contribution from the Potsdam Institute for Climate Impact Research (PIK) and led by Oregon State University scientists. Published today in BioScience, it cites global data from the Intergovernmental Panel on Climate Change (IPCC) in proposing “high-impact” strategies.
Depuis le début de la guerre en 2022, pas un jour sans qu’un drone ou un missile ne s’abatte sur l’Ukraine. Face à un danger devenu omniprésent, militaires, humanitaires et civils s’équipent en masse de détecteurs de drones.
The main report provides an integrated narrative, examining the central and vital role that the climate and natural environment play in ensuring health, resilience and prosperity for people, anchored in the EU’s vision for a sustainable Europe by 2050.

Iran’s parliament approved a measure to close the vital global trade route, through which more than a fifth of the world’s oil supply passes through daily
Un pattern mondial et des conséquences locales Une étude publiée le 4 juin 2025 dans Nature Ecology & Evolution, menée par des chercheurs de l’Université d’Umeå en collaboration avec l’Université de Reading, révèle un principe presque universel : Dans chaque région du globe, la biodiversité s’organise autour de "points chauds", des zones minuscules mais vitales, où la majorité des espèces apparaissent et se concentrent, avant de se raréfier en s’éloignant.
Paul Ingrassia sera à la tête du Bureau du procureur spécial des États-Unis.
Critical minerals, which are essential for a range of energy technologies and for the broader economy, have become a major focus in global policy and trade discussions. Price volatility, supply chain bottlenecks and geopolitical concerns make the regular monitoring of their supply and demand extremely vital.
Vitali Klitschko, maire de la capitale ukrainienne, a estimé dans un entretien diffusé vendredi à la BBC que l'Ukraine pourrait être contrainte céder des territoires afin d'obtenir une "paix temporaire" avec la Russie. Un scénario que l'ancien champion de boxe juge toutefois "injuste".
Larry Page. The name instantly evokes Google. He co-founded the search engine that reshaped how we explore the web. Now, whispers suggest he’s pivoting to AI manufacturing.Two publications lit the match: Tech in Asia and The Hindu. Both allege Page quietly built a team of robotics and data-savvy wizards. The result? A stealthy startup aimed at merging artificial intelligence with factory floors. The company’s identity remains hidden. Yet the words “AI manufacturing” capture attention. Manufacturing is massive, vital, and often riddled with inefficiencies. If Page wants to optimize it, the outcome could be game-changing.
The ocean ecosystem is a vital component of the global carbon cycle, storing enough carbon to keep atmospheric CO2 considerably lower than it would otherwise be. However, this conception is based on simple models, neglecting the coupled land-ocean feedback. Using an interactive Earth system model, we show that the role ocean biology plays in controlling atmospheric CO2 is more complex than previously thought. Atmospheric CO2 in a new equilibrium state after the biological pump is shut down increases by more than 50% (163 ppm), lower than expected as approximately half the carbon lost from the ocean is adsorbed by the land. The abiotic ocean is less capable of taking up anthropogenic carbon due to the warmer climate, an absent biological surface pCO2 deficit and a higher Revelle factor. Prioritizing research on and preserving marine ecosystem functioning would be crucial to mitigate climate change and the risks associated with it.
