By fate or design, this past week saw the posting of several different takes on flying.
From the relentless optimists at WorldChanging, a thoughtful post on a new biofuel under development at the University of North Dakota that is believed to be capable of replacing jet fuel and reducing greenhouse gas emissions.
From the confrontational English writer George Monbiot (often published in The Guardian) a grim post on the unhappy facts of flying, entitled "We Are All Killers," about how flying causes 2.7x as much global warming as the mere emission of carbon dioxide.
And from the professors at Environmental Economics, a post on the rationality of ignoring emissions when purchasing an airline ticket…and a terrific discussion in the comments.
What does it all mean? As far as I can tell, that the future is up for grabs at firesale prices.
