Global warmers hate to discuss clouds and snow because these act as giant natural mirrors bouncing sun heat back out to space. They especially don’t want to talk about man-made clouds and snow and the role of wind blown sand, dirt, and pollution which increase their formation. GWers are afraid to even research and model clouds because then the Luddite party would be over.
Got it in one. As I understand it, clouds in the troposphere increase heat retention more than they increase albedo, but clouds in the stratosphere work oppositely (they increase albedo more than heat reflection).
Sooooooo...the answer to global warming is to increase the sulfur content of jet fuel.
