I guess the Goth movement played its part in that...

Okay, that may be the outcome of a foreign speaker trying to pun..
See the lowest bit of my post. And:
The premise that aerosols will decrease the warming implies that the aerosols reflect the sunlight and don't absorb it. In the latter case the sun energy will be caught in the athmosphere as if it had reached the earth's surface.
So it depends on the kind of particles that the aerosols consist of and their individual albedo.
