"All options to fight climate crisis must be explored, says national academy, but critics fear side-effects"

"The US should establish a multimillion-dollar research programme on solar geoengineering, according to the country’s national science academy.

In a report it recommends funding of $100m (£73m) to $200m over five years to better understand the feasibility of interventions to dim the sun, the risk of harmful unintended consequences and how such technology could be governed in an ethical way.

The National Academies of Sciences (NAS) said cutting fossil fuel emissions remained the most urgent and important action to tackle the climate crisis. But it said the worryingly slow progress on climate action meant all options needed to be understood."
