Research programme will send aerosol injections into the earth’s upper atmosphere to study the risks and benefits of a future solar tech-fix for climate change

US scientists are set to send aerosol injections 20km up into the earth’s stratosphere in the world’s biggest solar geoengineering programme to date, to study the potential of a future tech-fix for global warming.

The $20m (£16m) Harvard University project will launch within weeks and aims to establish whether the technology can safely simulate the atmospheric cooling effects of a volcanic eruption, if a last ditch bid to halt climate change is one day needed.

Scientists hope to complete two small-scale dispersals of first water and then calcium carbonate particles by 2022. Future tests could involve seeding the sky with aluminium oxide – or even diamonds.
