Coupled with the many volcanic eruption data there is enough information to form preliminary conclusions about the weather effects...unlike the pissant "2 kg sack of flour equivalent" Gates intends to release.
So why is he doing this and why above Sweden? Well Kiruna is the home of Esrange, a sport port for satellite and balloon launches for research. Hmmm... seems as though similar research projects might already have been undertaken.
At first blush this sounds like an alternate backstory in Tom Clancy's "Rainbow Six" in which a billionaire efforts to reduce the worlds population by first globally dispersing a highly contagious and fatal virus at key transportation nodes...inducing global panic...and then offering up a vaccine that really is the coup de grace to the human race...can't help but think that maybe we're already part of Bill Gates'narrative.
What he says they'll be releasing may not be what is actually to be released. Might be interesting to check atmospheric patterns, especially wind currents...who know where those might lead.
I want to read that Clancy book.
