Geoengineering to reduce heat in one part of the world could bring droughts elsewhere, report says

Geoengineering to reduce temperatures in one part of the world could worsen droughts and hurricanes elsewhere, scientists have warned.

A report on the current science around techniques to reflect some sunlight back into space — known as solar radiation modification (SRM) — has found that internationally co-ordinated deployment could reduce global temperatures and some of the impacts of climate change.
