Projections of near-term climate change are a potential research tool. However, for that tool to be most useful, the physical basis for a prediction must be made clear. The basis for our projection of record 2026 global temperature is high climate sensitivity, with its implication that aerosol cooling was still increasing during the period 1970-2005. One consequence, global sea surface warming, already has important effects. Causes of climate change must be understood for policy purposes. Figures in this post and our recent papers are continually updated on our website.[1] We are also now on Substack[2].
And why when we do see it, we fail to act.

A vast system of Atlantic currents that delivers warmth to northern Europe is at risk of collapse, according to a growing body of research. The latest study to warn of its demise finds there is at least a 10 percent chance that a collapse may already be “locked in.”
The fluoropolymer industry is at it again. The industry’s most notable products are non-stick industrial coatings such as Teflon, made using forever chemicals (per- and polyfluoroalkyl substances: PFAS). But as the European Chemicals Agency (ECHA) starts to wind up its second public consultation on the proposed EU PFAS ban, the fluoropolymer industry is once again mobilising its customers to criticise alternatives to their products.

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
European scientists warn of consequences for weather patterns, the global climate and marine life
For most of the modern era, capitalism justified itself through growth. Industrial societies converted vast amounts of fossil energy into production, wealth, and rising living standards. Roads, bridges, power grids, schools, and public institutions expanded alongside the economy. Inequality and exploitation remained deeply embedded in the system, but they were partly obscured by a broader story of material progress.

A new report has uncovered the many risks of participating in climate and environmental protests across the world – and how more countries are criminalising and repressing this activity in a bid to keep it in check.
Some Western nations are using old legislation or enacting harsh new laws to restrict the right to peaceful protest and impose disproportionate penalties, a report warns. Governments in democratic countries in Europe and the global north are using overly punitive measures to crack down on environmental activists, according to a new report.
Environmental defenders across Europe, South Caucasus and Central Asia are increasingly facing legal pressure, intimidation and attempts to restrict their work. Non-governmental organisations warn about a steady rise in SLAPP lawsuits (1), defamation cases, claims for compensation for alleged damages and other tactics intended to discourage public scrutiny of industrial, mining and development projects with a negative impact on environment. Civic oversight is becoming more difficult, especially for those who challenge powerful economic or political interests.
Yet, as the climate crisis worsens, the civic space for climate protests is shrinking. Instead of focusing on meeting their commitments to reduce climate change, governments are threatening environmental protectors—from Indigenous communities defending their ancestral lands to young activists protesting the expansion of fossil fuels—with intimidation, legal harassment, and at times deadly violence. New forms of attacks are emerging, like the use of counterterrorism laws against climate activists, who are vilified in public and political discourse. And governments have been ratcheting-up their repression of such protests.
The criminalization and repression of climate and environmental activists have intensified globally in the past few years.1 These are forms of backlash against often impactful social movements. The repressive wave has sparked major concerns in many quarters, with the UN secretary general, the UN special rapporteur on environmental defenders, and many nongovernmental organizations (NGOs), politicians, and social movements speaking out against it.2 In this article I will draw on findings from a University of Bristol project that I led on this topic.3 Driven by a combination of state and corporate actors, the repression of climate and environmental protest is a truly worldwide phenomenon that takes place across the Global North and South.
Scientists have linked extreme weather events like excessive heat, flooding and wildfires to big emitter states’ failure to take urgent climate action despite the dangers posed to the rights of those living there and around the world. Governments worldwide are breaking electoral promises, defying court decisions over their lack of climate action, and ignoring warnings that have been voiced by international bodies for years.
In a landmark paper, the UN Special Rapporteur on Environmental Defenders warns that the continued State efforts to repress and criminalise environmental protests, including direct action and civil disobedience, are a threat to fundamental freedoms and democracy itself.
A Climate Rights International report exposes the increasingly heavy-handed treatment of climate activists in Australia, Germany, France, the Netherlands, Sweden, the UK and the US. It found the crackdown in these countries – including lengthy prison sentences, preventive detention and harassment – was a violation of governments’ legal responsibility to protect basic rights to freedom of expression, assembly, and association. It also highlights how these same governments frequently criticise regimes in developing countries for not respecting the right to protest peacefully.

Cet article rapporte la difficulté du secteur manufacturier en Grande Bretagne à faire face à l’augmentation du cout de l'énergie. Dans l'ombre de cet article apparait ce qui sera la réalité à un moment donné, sans pétrole bon marché, l'industrie manufacturière ne peut pas fonctionner dans les conditions actuelles. Le contrat social sera rompu et il faudra réinventer une manière de vivre ensemble. La situation en Grande Bretagne est peut-être exacerbée par le Brexit et la situation insulaire mais elle est l'avant-poste de ce qui attend une bonne part du monde industrialisé, à moins de relancer le charbon avec toutes les conséquences sur le dérèglement climatique et la santé des personnes que nous connaissons.

The Global Justice Project attempts to set out a new vision for global progress in the 21st century: grounding human development and equality in planetary habitability. It explores the conditions under which the world could move toward this horizon and traces an economically and ecologically consistent transition path from 2026 to 2100.
The Global Justice Project is a collective research initiative developed by the World Inequality Lab. Combining comparative historical data series from the World Inequality Database with global input-output tables, environmental accounts, labour force surveys and other sources, the project explores what a just distribution of socio-economic and environmental resources could look like at the global level from 2025 to 2100 – both between and within countries – in a way that is compatible with planetary boundaries. The project partly builds on the analysis and proposals set out in Thomas Piketty’s Brief History of Equality, extending them into a broader and more comprehensive global framework. The Global Justice Project is now available to explore on a dedicated website, that includes an interactive tool to explore the distributional pathways and climate scenarios behind the report.

While the term “Anthropocene” is well established across scientific disciplines and social spheres, interpretations are diverse. Taking account of the 2024 rejection by a geological commission to accept the Anthropocene as a geological epoch and the related scientific debate, here we offer a future-oriented perspective from the viewpoint of Earth system science. We describe different pathways in the Anthropocene up to the year 3,000, systematically characterizing them according to impacts and causes. We discuss the enormous global consequences of anthropogenic pressures on the Earth system and quantify the corresponding long-term commitment to change. Regarding the causes, we conservatively explore best-case and middle-of-the road emission scenarios, in combination with climate sensitivities drawn from within the IPCC likely range. We also discuss implications for Earth system resilience that could result in what we call worst case scenarios for Anthropocene outcomes. We conclude that, beyond the slow pace of
Our roadmap has been shaped by experts across the world, from UN agencies to grassroots movements. We call on political leaders at all levels to use it
- 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.
The British-Canadian computer scientist often touted as a “godfather” of artificial intelligence has shortened the odds of AI wiping out humanity over the next three decades, warning the pace of change in the technology is “much faster” than expected. Prof Geoffrey Hinton, who this year was awarded the Nobel prize in physics for his work in AI, said there was a “10% to 20%” chance that AI would lead to human extinction within the next three decades.
