> There is a lot of uncertainty in their findings, Dr. Fahey said, but the basic message is that trying to cool the planet by 0.5 degree Celsius (0.9 degree Fahrenheit), say, through the use of sulfur aerosols, would have some effect on ozone.
Why are these people qualified to mess with our climate?
By "these people" you mean the fossil fuel industries?
I don't like much the trend of being more outraged by people trying to fix the climate than by people breaking it
Seriously, it is already too late to not change it.
Nobody is fully qualified in the eyes of all laypeople so let us do nothing.
This is actually already happening somewhat, due to the use of high-sulfur fuel oil by container ships. Of course, the irony is that certain organisations are attempting to lower this sulfur content, without the realisation that it's actually helping to moderate the temperature of the planet.
The cooling effect from ship pollution is there, but it is a relatively small fraction of the ovrall cooling from atmospheric aerosols.
