You're assuming that if 1000 people decide not to fly to Prague some weekend that the number of planes burning jet fuel to fly there will be different. I don't think so. Maybe you can start a "Boycott Prague The Spoke City" campaign which, if wildly successful, will reduce demand to fly there by some discernable amount and thereby reduce the number of planes flying there and the amount of jet fuel they would've burned. Well, as long as the planes that aren't flying to Prague aren't used to fly to Heathrow or Frankfurt or some other hub city. Also doubtful. I do not intend on making ietf-discuss into a forum for discussing the pluses and minuses resulting from a degree centigrade temperature change but let me just say that "the planet wins" is a somewhat dubious statement.
