This is exactly why global climate warming change hysteria and exaggeration is so dangerous:
If we could pour a five-gallon bucket’s worth of sulfate particles per second into the stratosphere, it might be enough to keep the earth from warming for 50 years. Tossing twice as much up there could protect us into the next century.
A 1992 report from the National Academy of Sciences suggests that naval artillery, rockets and aircraft exhaust could all be used to send the particles up. The least expensive option might be to use a fire hose suspended from a series of balloons. Scientists have yet to analyze the engineering involved, but the hurdles appear surmountable.
A preemptive war on the climate? Pollution shock and awe? Ken Caldeira might have just identified the one battle the U.N. would be willing to fight.
