We work to ensure that carbon pricing and other climate policies cut pollution and drive a just transition towards zero-carbon societies.

Je sais exactement où tu es assis(e) en ce moment. Tu regardes un graphique des températures de surface de l’Atlantique Nord, observant une ligne rouge s’envoler vers un territoire inconnu et terrifiant. Encore une donnée horrible qui confirme ce que tu sais déjà. Tu ressens cette chute familière et creuse dans ton estomac en prenant conscience de la réalité biophysique : les systèmes de la planète se désagrègent.

A Letter to the Newly Awake. I know exactly where you are sitting right now. You are staring at a chart of North Atlantic sea surface temperatures, watching a red line spike into uncharted, terrifying territory. Yet another horrible data point proving what you already know. You feel a familiar, hollow drop in your stomach as you register the biophysical reality: the planet’s systems are unraveling.

La Belgique pourrait bien à l’avenir être confrontée à des feux de végétations et de forêts plus nombreux et plus intenses. Une menace sérieuse qui a mené à la création d’un réseau belge de lutte contre les feux de forêts : le "Belgian Wildfire Network".

Scenarios serve as a critical tool in climate change analysis, enabling the exploration of future evolution of the climate system, climate impacts, and the human system (including mitigation and adaptation actions). This paper describes the scenario framework for ScenarioMIP as part of CMIP7. The design process has involved various rounds of interaction with the research community and user groups at large. The proposal covers a set of scenarios exploring high levels of climate change (to explore high-end climate risks), medium levels of climate change (anchored to current policy), and low levels of climate change (aligned with current international agreements). These scenarios follow very different trajectories in terms of emissions, with some likely to experience peaks and subsequent declines in greenhouse gas concentrations in this century. An important innovation is that most scenarios are intended to be run, if possible, in emission-driven mode, providing a better representation of the Earth system uncert

Climate change is causing measurable harm globally1,2. Political and legal efforts seek to link these damages with specific emissions, including in discussions of loss and damage (L&D)3,4; however, no quantitative definition of L&D exists5,6, nor is there a framework to link past and future emissions from specific sources to monetized, location-specific damages. Here we develop such a framework, which is integrated with recent efforts to estimate the social cost of carbon7. Using empirical estimates of the non-linear relationship between temperature and aggregate economic output, we show that future damages from past emissions—one component of L&D—are at least an order of magnitude larger than historical damages from the same emissions. For instance, one tonne of CO2 emitted in 1990 caused US$180 in discounted global damages by 2020 ($40–530) and will cause an additional $1,840 through 2100 ($500–5,700). Thus, settling debts for past damages will not settle debts for past emissions. In other illustrative esti

Voici un article véritablement fascinant sur les origines physiques de la crise au Venezuela et une explication des raisons pour lesquelles il était dans l’intérêt des États-Unis de mener une guerre économique afin de prendre le contrôle des réserves pétrolières vénézuéliennes, à un moment où la rentabilité du pétrole américain était en déclin.

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.

Bij een steekproef in verschillende Europese landen zijn er TFA aangetroffen in graanproducten zoals brood, koekjes en speculaas. TFA is de kleinste variant van de forever chemical PFAS. De actiegroep Pesticide Action Network (PAN), die de testen liet uitvoeren, roept de overheid op om breder te meten naar TFA-resten in voedsel, en vraagt dat PFAS-bevattende pesticiden uitgedoofd worden.

Around 56 million years ago, Earth suddenly got much hotter. Over about 5,000 years, the amount of carbon in the atmosphere drastically increased and global temperatures shot up by some 6°C.

We propose a new paradigm, as toxicology currently lacks the proper perspective. From the 1950s to the 1970s, at least one-third of all toxicological testing in the United States, including for chemicals and drugs, was misleading scientists, and this worldwide issue persists today. Moreover, petroleum-based waste and heavy metals have been discovered in pesticide and plasticizer formulations. These contaminations have now reached all forms of life. Widespread exposure to chemical mixtures promotes health and environmental risks. We discovered that pesticides have never undergone long-term testing on mammals in their full commercial formulations by regulatory authorities or the pesticide industry; instead, only their declared active ingredients have been assessed, contrary to environmental law recommendations. The ingredients of these formulations are not fully disclosed, yet the formulations are in general at least 1000 times more toxic at low environmentally relevant doses than the active ingredients alone u

The latest Lancet Countdown report warns that health impacts of climate change are worsening, with millions dying needlessly each year due to fossil fuel dependence, growing greenhouse gas emissions, and failure to adequately adapt. As some countries and companies rollback on climate commitments, local and grassroots leadership is building momentum for a healthier future.​ The report represents the work of 128 experts from 71 institutions, monitoring progress across 57 indicators – from heat-related deaths to bank lending to fossil fuels – providing the most comprehensive assessment yet of the links between climate change and health.

We are an international group of researchers and practitioners interested in the emerging fields of post-growth and ecological macroeconomics. Our aim is to advance economic theory, methodology and policy in order to adequately address some of the biggest challenges of our time: climate change, rising inequality, and financial instability.

The doughnut-shaped framework of social and planetary boundaries (the ‘Doughnut’) provides a concise visual assessment of progress towards the goal of meeting the needs of all people within the means of the living planet1,2,3. Here we present a renewed Doughnut framework with a revised set of 35 indicators that monitor trends in social deprivation and ecological overshoot over the 2000–2022 period. Although global gross domestic product (GDP) has more than doubled, our median results show a modest achievement in reducing human deprivation that would have to accelerate fivefold to meet the needs of all people by 2030.

Les discours politiques sont imperméables aux idées de rupture, alors que la Terre atteint ses points de bascule, selon le chercheur Nathanaël Wallenhorst. Il en va pourtant de notre survie, explique-t-il.

This is not a call to despair, but an invitation to understand the forces driving the process of collapse, and to explore how we might navigate the descent with integrity, purpose, and care for the living world.

Nonylphenol is a toxic xenobiotic compound classified as an endocrine disrupter capable of interfering with the hormonal system of numerous organisms. It originates principally from the degradation of nonylphenol ethoxylates which are widely used as industrial surfactants. Nonylphenol ethoxylates reach sewage treatment works in substantial quantities where they biodegrade into several by-products including nonylphenol. Due to its physical–chemical characteristics, such as low solubility and high hydrophobicity, nonylphenol accumulates in environmental compartments that are characterised by high organic content, typically sewage sludge and river sediments, where it persists.
