Waters around the UK, Ireland, and France—particularly the southern North Sea—rank among the world's fastest-warming marine hotspots over the past half-century. Under a projected 3C warming scenario, warmer-water fish such as seabass and sardines will replace native cold-water species like cod, driving a 12% rise in fish and seabed invertebrate diversity. However, foundational phytoplankton and zooplankton are set to drop by 3% and 7% respectively, eroding the base of the food chain. The study has been submitted to a UK government review to help adapt future marine protected areas and fisheries management.

Warming seas around the UK and the wider north-east Atlantic could destabilise marine food webs, weaken ocean health and jeopardise food security by 2050, according to a four-year study.
Scientists who projected the impact of climate breakdown on four key groups of marine life crucial to maintaining ocean ecosystems in the region said their results challenged assumptions that in middle latitudes, such as the UK, marine biodiversity was likely to increase across the board.
Instead, their projections highlight a predator-prey imbalance that could “fundamentally reshape marine ecosystems” in unforeseen ways, they said.
The seas around the British isles, particularly the southern North Sea, have been identified as “marine climate hotspots”, one of 20 globally to have warmed the fastest over 50 years.
The new predictions, under a scenario of 3C (5.4F) of warming by 2100, found that while fish and seabed invertebrates may become more diverse by mid-century, key plankton groups lower in the food chain were likely to decline. This imbalance, the authors of the report said, could disrupt marine food webs and weaken the health and resilience of…
Environmental organisations including Greenpeace and Friends of the Earth are demanding an immediate halt to large computing infrastructure projects due to surging resource demands. The coordinated mobilisation targets the massive energy footprint driven by the artificial intelligence boom, which threatens national climate targets and strains public utilities. In response, technology companies maintain that these facilities remain vital engines for broader economic productivity and job creation.
Officials are collaborating with IIT Kanpur to deploy high-altitude cloud-seeding missions using substances like silver iodide to induce precipitation and settle atmospheric dust. The renewed intervention follows a persistent pollution crisis driven by low wind speeds that has pushed air quality into the very poor and severe categories across multiple monitoring stations. Further trial runs are expected to take place following the Diwali and Chhath holidays.
Severe weather triggered by a recent storm has escalated operational hazards for emergency response teams deployed in southern India. Operations have become increasingly precarious as intense downpours continue across affected districts. Authorities now face the compounding challenge of safeguarding rescue personnel while maintaining ongoing relief efforts.
