100,000 flights per day at altitudes from 25,000 to 40,000 ft, mandating a tiny amount of sulfur in the aviation fuel could probably halt and reverse global warming.

The point of this post is to make you think - there's a 100,000 flights every day at high altitude. They will be burning and spitting stuff into the atmosphere.
Is there some compound or substance that can be included that would dramatically counter-act CO2 greenhouse effect?
The answer is: almost certainly, yes. What are its second order effects? Is Sulfur Dioxide the best choice? These are important questions to determine. All we know right now is - SO2 had a dramatic effect on warming when it was emitted by ships.
Any which way you slice it, the fastest way to deploy a solution to an industrial scale problem is to use industrial scale distribution. Planting a tree and recycling a pop can will make you feel better.
If you want to actually change the world, change industry.
This was all a pretty off-hand tweet but it turns out Scott Kirby, CEO of United Airlines, suggested SO2 injection into aviation fuel as a climate change tool last month in an internal all-hands meeting.
