UK to fund small-scale outdoor experiments in geoengineering
The Guardian
|April 23, 2025
UK scientists are to launch outdoor geoengineering experiments as part of a £50m government-funded programme.
The experiments will be small-scale and rigorously assessed, according to Advanced Research and Invention Agency (Aria), the organisation backing the plan, and will provide "critical" data needed to assess the potential of the technology.
The programme, along with another £11m project, will make the UK one of the biggest funders of geo-engineering research in the world.
Geoengineering is controversial and some previous planned experiments have been cancelled after strong opposition.
Most proposals aim to block sunlight reaching the Earth's surface, for example by launching clouds of reflective particles into the atmosphere or using sea water sprays to make clouds brighter.
