About the only way the aerosol particles could contribute to cooling would be if they reflected light particles (solar energy) away from the planet. But as the earlier poster stated and demonstrated with an image, the Far East (population ~2 Billion) is pumping out more aerosol pollutants then us capitalistic Americans (200-300 million) did a few decades ago. So no warming should be occurring now if these aerosols caused cooling a few decades ago. Besides, if an increase in retained energy or heat was the primary affect we are currently experiencing, we should not be setting any new cold temperature records. Yet, we did here a few months ago. Also had snow on the ground for the first time in about 25 years. This was followed 4 weeks later by new heat records. Strange extremes indeed. My guess would be that energetic input is the primary current affect. Mostly caused by increased solar radiation along with some increase in human produced energy. So we have some general warming along with stronger extremes in winter and summer. I think in the short run perhaps dealing with the extremes is going to be more important then dealing with a slight warming trend which may not last very long.
I wished that the interviewer had told her that you need cold to turn that moisture into snow. But alas, there was no such followup.
