Global Dimming - a new global threat

I watched this film called Global Dimming, which you can also watch here, that basically details another global climate changer: the diminishing of solar radiation due to visible particulates. The phenomenon, coined global dimming, works contrary to global warming as mean temperature is concerned. However, it also changes the dynamics of the atmosphere, causing extensive droughts.

What that means is that if we don't stop global dimming, things like what happened in Ethiopia in 1984 will happen again, more often and worse. But if we do, while doing nothing about greenhouse gases, the global temperature will rise well faster than current climate models predict, because they didn't take into account global dimming as a factor.

It is a very interesting, albeit a bit over dramatic, film to watch so... watch it!
