The Sooty Greenhouse: My New Story For Yale Environment 360

The soot we loft into the sky is a remarkably mysterious player in the climate game. At Yale Environment 360, I report on the most comprehensive study yet of soot, which reveals that it’s trapping huge amounts of heat. Yet getting rid of all the soot we put in the atmosphere wouldn’t change the climate much. Check out my piece for the solution to that paradox.

    I suspect soot is so puzzling because its effects are contradictory. It increases some things and reduces others. More soot in the air reduces insolation, for example, producing a net effect on global warming that is hard to quantify.
