Scientists studying the effects of aerosols on the Atlantic Ocean confirm that smoke, dust, and pollution indeed may moderate the effects of global warming there. Aerosols both reduce cloud droplet size and increase shallow cloud cover. And the cloud cover effects are much more important than the effects of smaller droplet size.
So, pollution is cool and climate models underestimate the impact of aerosols and thus exaggerate the likely amount of warming. I guess this comes under the good news category, but...
