Les grandes puissances déploient des initiatives de connectivité qui redessinent la carte du monde. La Chine avec ses Nouvelles Routes de la soie, l’Union européenne et son Global Gateway, les États-Unis et le G7 à travers le Build Back Better World ou B3W/PGII… Tous ces projets traduisent une même ambition : organiser, sécuriser et contrôler l’internationalisation de l’économie, plutôt que la subir.

La chaleur extrême, davantage que le manque de précipitations, est en train de devenir le principal facteur de sécheresse sur le continent européen, selon une étude du réseau de scientifiques World Weather Attribution publiée jeudi.

Une sécheresse des sols comme celle que connaît actuellement la Belgique est onze fois plus probable aujourd’hui qu’avant le réchauffement climatique. C’est ce qu’il ressort d’une nouvelle étude du consortium international "World Weather Attribution" (WWA). Explications.

Combien y a-t-il d'habitants dans le monde ? La population mondiale a atteint 8 milliards le 15 novembre 2022 selon les Nations Unies. Compteur de la population mondiale en direct avec fiches de données, graphiques, cartes et données de recensement concernant les chiffres actuels, historiques et futurs de la population mondiale, les estimations, les taux de croissance, les densités et la démographie

Alors que la Chine et les États-Unis se livrent une guerre sans merci sur le terrain de l’intelligence artificielle, le président Xi Jinping a fait une déclaration assez surprenante lors de l’ouverture de la récente World AI Conference (WAIC) à Shanghai. Le dirigeant a proposé de faire en sorte que l’IA devienne un « bien public mondial » via des modèles open-source, une vision contrastant fortement avec celle des Etats-Unis.

Pour les scientifiques du World Weather Attribution, qui analysent le rôle du changement climatique dans les phénomènes météorologiques extrêmes, la vague de chaleur actuelle est directement liée au réchauffement causé par les émissions humaines de gaz à effet de serre. Une nouvelle alerte, qui confirme que ces épisodes extrêmes sont amenés à se multiplier et à s’intensifier avec le dérèglement climatique.

Le 4 juin dernier, le World Inequality Lab (WIL) a lancé le « Global Justice Project », un programme destiné à « stimuler la recherche, l’élaboration des politiques et l’engagement citoyen afin de façonner un 21ème siècle plus juste, plus démocratique et plus durable ». Pour l’heure, il prend la forme d’un rapport, A Plan for Equality & Prosperity Within Planetary Boundaries, qui prolonge sept working papers du WIL – près de 970 pages de travail scientifique. L’effort est colossal. Comme le résume l’un des co-auteurs de l’étude, l’économiste Lucas Chancel, spécialiste des inégalités (Insoutenables inégalités, 2021) et de l’énergie (Énergie et inégalités, 2025) : « 24 mois de travail, 45 chercheurs venus du monde entier, combinant les connaissances issues de l’économie, de l’histoire et des sciences du climat ». À l’échelle de l’histoire de la macroéconomie, c’est l’équivalent d’une pyramide.

La vague de chaleur qui accable l'Europe depuis plusieurs jours aurait été "quasiment impossible" il y a 50 ans et le changement climatique en est "incontestablement" la cause, affirme le World Weather Attribution (WWA) dans une analyse "rapide" publiée vendredi.

Misschien is het probleem niet dat toekomstscenario's zoals die van het Global Justice Report onhaalbaar zijn, maar dat ze net iets te veel vragen stellen over onze huidige realiteit.

L’humanité peut améliorer les niveaux de vie, réduire les inégalités et maintenir le réchauffement climatique en dessous d’une hausse de 2 °C, selon une vision ambitieuse de la survie de la planète rapportée la semaine dernière par The Guardian. À une époque marquée par l’angoisse écologique, c’est une affirmation remarquablement optimiste. Cet optimisme provient du Global Justice Report, élaboré par le World Inequality Lab de Thomas Piketty. […] Ce rapport va à contre-courant de l’époque actuelle. La démagogie anti-immigration, le retour en grâce des combustibles fossiles, les attaques contre le multilatéralisme et la captation du pouvoir par les milliardaires s’opposent tous à la capacité redistributive de l’État que le rapport juge nécessaire. Pourtant, l’équipe du professeur Piketty affirme que la décarbonation, la « sobriété » et l’égalité peuvent permettre à la majorité de mener une vie agréable.

- Artificial intelligence could pose a "more urgent" threat to humanity than climate change, AI pioneer Geoffrey Hinton told Reuters in an interview on Friday. Geoffrey Hinton, widely known as one of the "godfathers of AI", recently announced he had quit Alphabet, opens new tab after a decade at the firm, saying he wanted to speak out on the risks of the technology without it affecting his former employer.

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.

Les systèmes d’intelligence artificielle générative, qui parlent si bien, ne comprennent pas encore le monde. De nouvelles méthodes physiques ou statistiques comme les world models, ou « modèles de monde », permettraient de les doter d’une forme de sens commun, qui leur servirait à mieux simuler la réalité et de mieux interagir avec elle.

A climate monster is growing right now in the Pacific Ocean, perhaps the most fearsome El Niño since before scientists even began modeling them. They now know the pattern quite well: A marine heat-wave in the Pacific Ocean scrambles global weather and produces in some places more intense droughts and in others more intense rainfall and flooding; disruptions to hurricane patterns and monsoon seasons, which can cause widespread crop failures; and much more punishing heat.

Closed-door talks over the World Bank’s climate agenda have stalled, as the US pushes to scrap green targets and expand support for fossil fuels

Oil has empowered capitalism, and some of the world’s most exploitative regimes. Move away from it and we can solve some of the key issues we face

What is currently happening in Brussels under the guise of regulatory simplification is being presented as something technical and logical. Less regulatory pressure, more competitiveness. A series of so-called omnibus bills are intended to streamline legislation. Reporting obligations are being limited and reassessments of raw materials postponed. It sounds like administrative efficiency. In Washington, things are moving even faster: Trump is dismantling the basis for climate laws while the world continues to warm up. The framing is the same: rules slow down businesses, and a slowed-down business community makes us poor. But that reasoning assumes something that is not true: that everyone wants the same thing from the market.

Doyne Farmer says a super-simulator of the global economy would accelerate the transition to a green, clean world

The world seems headed into another El Nino, just 3 years after the last one. Such quick return normally would imply, at most, an El Nino of moderate strength, but we suggest that even a moderately strong El Nino may yield record global temperature already in 2026 and still greater temperature in 2027. The extreme warming will be a result mainly of high climate sensitivity and a recent increase of the net global climate forcing, not the result of an exceptional El Nino, per se. We find that the principal drive for global warming acceleration began in about 2015, which implies that 2°C global warming is likely to be reached in the 2030s, not at midcentury.

HAMBOURG — Depuis quelque temps déjà, les climatologues débattent d’une hypothèse inquiétante : le réchauffement climatique est-il en train de s’accélérer ? La Société allemande de physique et la Société météorologique allemande mettent désormais en garde contre ce phénomène dans une déclaration commune. L’hebdomadaire allemand Die Zeit s’est entretenu à ce sujet avec Klaus Richter, président de la Société allemande de physique, et Frank Böttcher, président de la Société météorologique allemande.

With warming set to pass the critical 1.5-degree limit, scientists are warning that the world is on course to trigger tipping points that would lead to cascading consequences — from the melting of ice sheets to the death of the Amazon rainforest — that could not be reversed.

The decline in the health of nature around the world poses a threat to the UK's security and prosperity, an intelligence committee has concluded in a long-awaited report. The document warns of "cascading risks" from the degradation of some of the planet's most important ecosystems, including conflict, migration and increased competition for resources.

Like living beyond your financial means, using more water than nature can replenish can have catastrophic results.

Flagship report calls for fundamental reset of global water agenda as irreversible damage pushes many basins beyond recovery

US demand to own Greenland leaves little scope for compromise, and forcing the issue would entail end of Nato Greenland, with a population of fewer than 57,000, might not seem to be the territory on which the future of the relationship between Europe and the US, the viability of Nato as the world’s most successful defence alliance, or even the fractured relations between the UK and Europe would be determined. But battlefields are sometimes the product of chance, rather than choice. It now feels as if Donald Trump’s threat to impose 10% tariffs on eight fellow Nato states for sending troops last week to support Greenland’s sovereignty may be one of those clarifying moments in which Europe had no option. Successive European leaders condemned Trump’s blackmail and intimidation on Sunday and they sounded as if they meant it.

Satellite analysis warns that widespread land subsidence threatens 1.6 billion people by 2040, with 86% of the at-risk population concentrated in Asia

The “Fueling Ecocide” investigation, led by Environmental Investigative Forum (EIF) and European Investigative Collaborations (EIC), reveals that oil and gas licences overlap with 7,000 protected areas worldwide. The total overlap is 690,000 km², an area bigger than the size of France — despite existing regulations and ongoing efforts to safeguard key biodiversity zones.

From floods to droughts, erratic weather patterns are affecting food security, with crop yields projected to fall if changes are not made

Rob Hopkins has spent the past decades exploring one question: what if we could fall in love with the future? As co-founder of Transition Network and Transition Town Totnes, and author of four books, he travels the world helping communities cultivate imagination, longing and possibility. He believes that the transition we so urgently need depends on one thing above all: imagination.

Data from World Inequality Report also showed top 10% of income-earners earn more than the other 90%

I always say that models are not predictions; they are qualitative illustrations of what the future could be. But as the future gets closer to the present, models can start being seen as predictive tools. It is the weather/climate dichotomy, so aptly exploited to confuse matters by politically minded people in the discussion about climate. Right now, we are getting close to the point that we could forecast a collapse in the same way as we can forecast the trajectory of a tropical storm. So, you remember how “The Limits to Growth” generated a long term forecast in 1972. Here it is

The UK has announced much harsher rules for asylum seekers including the prospect of more deportations for those whose applications fail. The US is trebling the size of its deportation force. The EU is doubling its border budgets. And in the coming decades, hundreds of millions of people might be displaced by ecological changes.

Antibiotic use in farming is now rampant. How meat is produced in China may mean the drugs you need here won’t work, says Prof Devi Sridhar, chair of global public health at the University of Edinburgh

Ahead of the United Nations climate talks in Brazil, advocacy groups are pushing for companies and governments to set meaningful emissions targets to lower emissions from livestock.

A climate-focused report out of Europe throws serious shade at plug-in hybrid electric (PHEV) cars, pointing out that they emit nearly as much carbon dioxide emissions as combustion engine-powered vehicles. In fact, it highlights how real-world emissions from supposedly greener PHEVs has increased over the years above officially recorded figures to nearly five times. Yikes! The findings come from the European Federation for Transport and Environment (T&E), a clutch of non-government organizations focused on sustainable transport policy across the continent. The report has been published ahead of a review of automotive CO2 emission standards, which would see Europe continue to sell plug-in hybrid electric vehicles beyond 2035, when they're set to be phased out in order to meet EU climate targets.

German scientists warn global warming is accelerating faster than expected, raising the risk of a 3 °C rise by 2050 and forcing Europe to confront unthinkable adaptation plans.

The Production Gap Report finds that 10 years after the Paris Agreement, governments plan to produce more than double the volume of fossil fuels in 2030 than would be consistent with limiting global warming to 1.5°C, steering the world further from the Paris goals than the last such assessment in 2023.

Much attention today focuses on uncertainties affecting the future evolution of oil and natural gas demand, with less consideration given to how the supply picture could develop. However, understanding decline rates – the annual rate at which production declines from existing oil and gas fields – is crucial for assessing the outlook for oil and gas supply and, by extension, for market balances. The International Energy Agency (IEA) has long examined this issue, and a detailed understanding of decline rates is at the heart of IEA modelling and analysis, underpinning the insights provided by the scenarios in the World Energy Outlook. This new report – based on analysis of the production records of around 15 000 oil and gas fields around the world – explores the implications of accelerating decline rates, growing reliance on unconventional resources, and evolving project development patterns for the global oil and gas supply landscape, for energy security and for investment. It also provides regional insights
