Newly discovered ‘Criegee biradicals’ could be used to cool the planet

Although I’m skeptical about the pie-in-the-sky stuff that I’m reading so far, the possibilities are interesting.

Basically, scientists have discovered an oxidizing molecule that reacts very rapidly (hence why they’re hard to find – they disappear so quickly in most conditions) with atmospheric compounds to form sulfates and nitrates, which form the nuclei for cloud droplets.  Cloud cover acts as a sunshield, so if we were able to increase the number of these molecules entering the atmosphere, it’d probably cool the planet.

Whether that’s a good idea is another question, of course.
