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 ...

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, ...

A new climate modeling study shows that cooling the planet with particles injected into the upper atmosphere might be easier and cheaper than previously believed. While scientists still warn of ...

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 ...

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.

It might sound like a Bond villain's sinister plot, but dimming the sun could be the key to fighting climate change. Scientists believe a controversial geoengineering technique called stratospheric ...
