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.

Les pays du monde entier se trouvent à un moment critique de la bataille contre la pollution plastique. Alors que les négociations autour d’un traité mondial sur les matières plastiques touchent à leur fin, l’OCDE présente, dans ce rapport, les résultats d’un exercice de modélisation de scénarios d’action fondés sur différents types d’intervention : limiter la production et la demande, promouvoir l’écoconception, augmenter le recyclage et fermer les voies de rejet. Ce rapport éclaire sur les avantages environnementaux et les conséquences économiques qui pourraient découler des actions engagées pour mettre fin à la pollution par les plastiques d’ici à 2040, selon différents niveaux d’ambition : quels pays agissent, le caractère rigoureux des mesures et les phases du cycle de vie des plastiques auxquelles elles s'appliquent.

Identifying the socio-economic drivers behind greenhouse gas emissions is crucial to design mitigation policies. Existing studies predominantly analyze short-term CO2 emissions from fossil fuels, neglecting long-term trends and other GHGs. We examine the drivers of all greenhouse gas emissions between 1820–2050 globally and regionally. The Industrial Revolution triggered sustained emission growth worldwide—initially through fossil fuel use in industrialized economies but also as a result of agricultural expansion and deforestation. Globally, technological innovation and energy mix changes prevented 31 (17–42) Gt CO2e emissions over two centuries. Yet these gains were dwarfed by 81 (64–97) Gt CO2e resulting from economic expansion, with regional drivers diverging sharply: population growth dominated in Latin America and Sub-Saharan Africa, while rising affluence was the main driver of emissions elsewhere. Meeting climate targets now requires the carbon intensity of GDP to decline 3 times faster than the global

"Curtis Yarvin, également connu sous le pseudonyme de Mencius Moldbug, est devenu un sujet d'intérêt croissant dans les publications françaises, particulièrement depuis 2024. Cet informaticien et blogueur américain, théoricien de l'idéologie néoréactionnaire, a fait l'objet d'analyses approfondies qui examinent tant sa philosophie politique que son influence présumée sur l'administration Trump." ...

Climate Obstruction Across Europe, coordinated by the Climate Social Science Network (CSSN) and published via Oxford University Press, reveals extensive networks impeding climate action within the region and surrounding states. In Italy and Germany, far-right networks spread misinformation by questioning climate science’s validity, while in Spain and the UK, blame-shifting and deflecting responsibility for climate action are common. European-based fossil fuel industries, like Shell, engage in greenwashing, by framing gas as a ‘bridging technology crucial for the energy transition’, delaying genuine progress.

Mitigating climate change necessitates global cooperation, yet global data on individuals’ willingness to act remain scarce. In this study, we conducted a representative survey across 125 countries, interviewing nearly 130,000 individuals. Our findings reveal widespread support for climate action. Notably, 69% of the global population expresses a willingness to contribute 1% of their personal income, 86% endorse pro-climate social norms and 89% demand intensified political action. Countries facing heightened vulnerability to climate change show a particularly high willingness to contribute. Despite these encouraging statistics, we document that the world is in a state of pluralistic ignorance, wherein individuals around the globe systematically underestimate the willingness of their fellow citizens to act. This perception gap, combined with individuals showing conditionally cooperative behaviour, poses challenges to further climate action. Therefore, raising awareness about the broad global support for climat

Disposition des Québécoises et des Québécois envers les défis climatiques

Compte-tenu du rythme et de l'ampleur de l'effort à fournir dans la lutte contre le réchauffement climatique, il devient indispensable de prendre en compte dès maintenant son impact sur l'économie. La Première ministre a confié à Jean Pisani-Ferry une mission d'évaluation des impacts macroéconomiques de la transition écologique, dont France Stratégie assure le secrétariat et qui bénéficie de l'appui de l'Inspection générale des finances. Le rapport de synthèse publié aujourd’hui vise à améliorer la compréhension des impacts macroéconomiques de la transition climatique, en sorte que les décisions qui vont devoir être prises soient « le mieux informées possible ».

INTERLAKEN, Switzerland, March 20, 2023 -- There are multiple, feasible and effective options to reduce greenhouse gas emissions and adapt to human-caused climate change, and they are available now, said scientists in the latest Intergovernmental Panel on Climate Change (IPCC) report released today. ...

Les douze leviers pour intervenir dans un système ont été proposés par la scientifique et analyste des systèmes américaine Donella Meadows au sujet des limites environnementales à la croissance économique.

UN Climate Change News, 26 October 2022 – A new report from UN Climate Change shows countries are bending the curve of global greenhouse gas emissions downward but underlines that these efforts remain insufficient to limit global temperature rise to 1.5 degrees Celsius by the end of the century.

La protection et la restauration des forêts, des mangroves et des récifs coralliens, la préservation ou la restauration des zones humides, ou encore la création d’espaces verts urbains... ces solutions dites Solutions fondées sur la nature (SfN) s’inspirent et s’appuient sur la nature dans le but de générer des bénéfices aux niveaux environnemental, social et économique.

Par cette Déclaration, les parlementaires du monde entier s’unissent pour appeler à un moratoire sur l’exploitation minière des grands fonds marins, pour adopter un principe de précaution afin de préserver ce patrimoine commun de l’humanité, et pour protéger les droits humains de toutes les personnes qui dépendent des océans.

Metals will play a central role in successfully building Europe’s clean technology value chains and meeting the EU’s 2050 climate-neutrality goal. In the wake of supply disruptions from the COVID-19 pandemic and Russia's invasion of Ukraine, Europe’s lack of resilience for its growing metals needs has become a strategic concern. This study evaluates how Europe can fulfil its goal of “achieving resource security” and “reducing strategic dependencies” for its energy transition metals, through a demand, supply, and sustainability assessment of the EU Green Deal and its resource needs . It concludes that Europe has a window of opportunity to lay the foundation for a higher level of strate- gic autonomy and sustainability for its strategic metals through optimised recycling, domestic value chain investment, and more active global sourcing. But firm action is needed soon to avoid bottlenecks for several materials that risk being in global short supply at the end of this decade.

BERLIN, Feb 28 – Human-induced climate change is causing dangerous and widespread disruption in nature and affecting the lives of billions of people around the world, despite efforts to reduce the risks. People and ecosystems least able to cope are being hardest hit, said scientists in the latest Intergovernmental Panel on Climate Change (IPCC) report, released today.

Le Giec et l\'IPBES sont clairs, dans leur rapport d\'atelier coparrainé, sur le fait que nous ne pouvons réussir à inverser les crises du changement climatique et de la perte de biodiversité que par une réponse intégrée et ambitieuse.

In Paris, all governments solemnly promised to come to COP26 with more ambitious 2030 commitments to close the massive 2030 emissions gap that was already evident in 2015. Three years later the IPCC Special Report on 1.5°C reinforced the scientific imperative, and earlier this year it called a climate “code red.” Now, at the midpoint of Glasgow, it is clear there is a massive credibility, action and commitment gap that casts a long and dark shadow of doubt over the net zero goals put forward by more than 140 countries, covering 90% of global emissions.

The world is dangerously off track to meet the Paris Agreement goals. The risks are compounding. Without immediate action the impacts will be devastating in the coming decades.

A new report, published on 14 March, 2021 in the Royal Swedish Academy of Sciences’ journal Ambio, points out that humanity is hurtling towards destruction unless we have the collective wisdom to change course quickly.
