"This is a film that demands action. It reveals that we may have grossly underestimated the speed at which our climate is changing. At its heart is a deadly new phenomenon. One that until very recently scientists refused to believe even existed. But it may already have led to the starvation of millions. Tonight Horizon examines for the first time the power of what scientists are calling Global Dimming."
Very riveting documentary.

Global Dimming
This is an excellent documentary that must be understood to get at some of the roots of the debate about data regarding global warming.
The average global 10% of dimming found by the researchers and attributed to particulate matter in the atmosphere helped reconcile differences between some of the predicted (theoretical) warming and actual (observed) warming. It also explains why some have advocated injecting additional particulate matter into the atmosphere to combat global warming.
It should be noted that an environmental axiom is that you can NEVER get one isolated reaction to any human attempt to do something (like an "artificial", induced "remedy" to a perceived problem) to change something in nature. Doing so usually provokes additional effects in keeping with the law of unintended consequences.
