Researchers at the University of Delaware have […]

Welcome to Carbon Brief’s DeBriefed. An essential guide to the week’s key developments relating to climate change. This week US to pull out from UNFCC, IPCC CLIMATE RETREAT: The Trump administration announced its intention to withdraw the US from the world’s climate treaty, CNN reported. The move to leave the UN Framework Convention on Climate Change […]

The Trump administration in the US has announced its intention to withdraw from the UN’s landmark climate treaty, alongside 65 other international bodies that “no longer serve American interests”. Every nation in the world has committed to tackling “dangerous anthropogenic interference with the climate system” under the 1992 UN Framework Convention on Climate Change (UNFCCC). […]

Artificial intelligence has captured headlines recently for its rapidly growing energy demands, and particularly the surging electricity usage of data centers that enable the training and deployment of the latest generative AI models. But it’s not all bad news — some AI tools have the potential to reduce some forms of energy consumption and enable cleaner grids. […]

Every autumn, as the Northern Hemisphere moves toward winter, Judah Cohen starts to piece together a complex atmospheric puzzle. Cohen, a research scientist in MIT’s Department of Civil and Environmental Engineering (CEE), has spent decades studying how conditions in the Arctic set the course for winter weather throughout Europe, Asia, and North America. His research […]

Gas sensors developer Alphasense has introduced what’s said to be the world’s first galvanic lead-free oxygen sensor (O2-A2-GLF) for industrial safety applications. The O2-A2-GLF sensor is engineered as a direct replacement for existing two-pin oxygen sensors used in portable and fixed gas instruments. It is designed to deliver reliable performance in demanding industrial environments, maintaining […]

The US, which has announced plans to withdraw from the global climate treaty – the UN Framework Convention on Climate Change (UNFCCC) – is more historically responsible for climate change than any other country or group. Carbon Brief analysis shows that the US has emitted a total of 542bn tonnes of carbon dioxide (GtCO2) since 1850, by […]

The James M. and Cathleen D. Stone Center on Inequality and Shaping the Future of Work officially launched on Nov. 3, 2025, bringing together scholars, policymakers, and practitioners to explore critical questions about economic opportunity, technology, and democracy. Co-directed by MIT professors Daron Acemoglu, David Autor, and Simon Johnson, the new Stone Center analyzes the forces that contribute to growing […]
Enhanced rock weathering (ERW) is a promising solution for durable carbon dioxide removal (CDR) which involves spreading finely ground alkaline rocks (such as basalt and other silicate rocks) over land. Scientists posit that the alkaline materials will react with carbon dioxide in the air, sequestering it in mineral or aqueous form, potentially for tens of […]

The program addresses the urgent problem of storing excess electricity generated on windy or sunny days, to make it available when demand exceeds supply. A new research collaboration aims to develop GPStore, a pioneering long-duration energy storage technology that could play a vital role in supporting the UK’s transition to net zero. The project, led […]

The findings appear to reveal an important role for the waste material – defined as plastic fragments smaller than five millimeters in size – in a process considered crucial to regulating the Earth’s temperature. The ubiquity of microplastics is now widely appreciated, even as significant gaps endure in our understanding of how exactly they arrive […]

Planning approvals for battery, wind, and solar projects in Great Britain (GB) almost doubled in 2025, with more than 45GW of capacity approved.1 This is 96% higher than the previous year’s 23GW, and enough to power 12.9 million homes. (Words: Cornwall Insight). Fresh analysis from Cornwall Insight reveals that this boom is being driven by […]

What is patient privacy for? The Hippocratic Oath, thought to be one of the earliest and most widely known medical ethics texts in the world, reads: “Whatever I see or hear in the lives of my patients, whether in connection with my professional practice or not, which ought not to be spoken of outside, I […]
