This week, there was talk in the news about attempting to counteract global warming by proactively cooling the atmosphere.
The rationale for this is that many scientists believe we are very near, if not past the "tipping point", which will soon result in accelerated warming and the anticipated disasters that are expected to follow forthwith.
The method I heard discussed was a concept that involved shooting a material into the upper atmosphere that would block the sun's heat from entering the atmosphere.
My opinion on this is that it is probably too risky. Any intentional action that could be substantial enough to change the temperature of the entire atmosphere could conceivably have substantial unforeseen side effects.
Thanks but no thanks!
