EU should ban space mirrors and other solar geoengineering, scientists say

European Commission scientific advisers say technology to offset global heating could wreak havoc on weather

Europe should ban space mirrors, cloud whitening and other untested tools being touted to reflect the sun’s rays, the European Commission’s scientific advisers have said, but said the door should be left open for research into their development.

The scientists said the risks and benefits of solar radiation modification (SRM) – also known as solar geoengineering – were “highly uncertain”. They called for an EU-wide moratorium on using it as a way to offset global heating.
