Yes, the new environmentalist solution, lets go back to producing lots of sulfur dioxide smog like we had in the 40's and 50's. But lets not do it the cheap old fashioned way by burning less processed diesel and gas. Let us burn sulfur directly and pump lots of it day and night into our atmosphere. Apparently the last thing most environmentalists want to do is solve the problem. Why not make a first ditch attempt and plant more trees and grasslands to most efficiently solve the problem of excess CO2 in the atmosphere? Unless you do that first you are part of the problem. The environmentalists should be happy. It looks like China is progressively doing it's part already. Also, don't kid yourself, sulfur dioxide is even heavier than CO2. It will fall down to the bottom of our atmosphere where we and everything else lives and have it's negative consequences on us all. Al Gore, you are failing all your constituents by not looking at things the way they really are. Lies and hare brained schemes will not solve the problem.
