I've started reading John McNeill's best know work to date:

John McNeill. Something New Under the Sun: An Environmental History of the 20th-Century World. New York: Norton, 2000.

This is an impressive book which I will probably need to acquire a copy of rather than borrowing from the library.

I was doing a bit of research into what Prof. McNeill has published lately. I came across this recent Georgetown University promotional interview in which Prof. McNeill addresses a few different environmental issues.

I hope that Mr. Obama finds a way to include Prof. McNeill's expertise into his decision making on the environment as I would regard him as a credible authority. Prof. McNeill's credentials includes, among other things, two Fulbright Awards, a Guggenheim fellowship, a MacArthur Genius Grant, and a fellowship at the Woodrow Wilson Center.
