Scientists for years have argued over drastic action to cool a warming world. Among the most widely debated is stratospheric aerosol injection, or SAI— injecting reflective particles into the upper ...

Scientists are taking the once-radical concept of dimming the sun through stratospheric aerosol injection (SAI) seriously, but a Columbia University team warns that reality is far messier than models ...

I've heard for several years about stratospheric aerosol injection SAI is a known way to artificially reduce the temperature of the earth but has an issue with a bounce back effect from stopping it.

Holy sun-repellant spray, Batman! Could injecting billions of kilograms of sunlight-dimming aerosols into the atmosphere save the planet from industrial climate destruction? Or is that just ...

A technique to cool the planet, in which particles are added to the atmosphere to reflect sunlight, would not require developing special aircraft but could be achieved using existing large planes, ...
