Experiments to dim the Sun will be approved within weeks

The UK government plans to allow experiments aimed at dimming sunlight to combat global warming. The Advanced Research and Invention Agency (Aria) will announce £50 million in funding for projects in the coming weeks. Prof Mark Symes emphasized the focus on “small controlled outdoor experiments” using methods like Stratospheric Aerosol Injection and Marine Cloud Brightening.

Skepticism exists regarding the potential adverse effects of geoengineering, but concerns about rising carbon dioxide levels highlight the need for innovative solutions. Evidence suggests that injecting particles into clouds can enhance reflectivity and cool the planet.

Field trials could lead to large-scale applications within a decade if successful, along with supporting studies and climate monitoring efforts.
