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.

Developing countries urge biggest polluters to act as Trump’s return to the White House heightens geopolitical turmoil

L’administration Trump a commencé à supprimer les références à la crise climatique des sites web de plusieurs ministères et agences fédérales américaines, menaçant l’accès à des données scientifiques clés et, par conséquent, entravant la lutte contre le changement climatique.

Dans le cadre de la transition énergétique, les tensions d'approvisionnement autour des matières premières stratégiques pourraient être « significativement réduites » par le développement des politiques de recyclage, souligne l'Agence internationale de l'énergie (AIE) dans un premier rapport consacré à ce sujet publié ce 18 novembre(1).

Record emissions, temperatures and population mean more scientists are looking into possibility of societal collapse, report says
