Elizabeth Kolbert has written a long article in the New Yorker magazine about James Hansen, NASA's chief climate scientist, which unfortunately is only available to subscribers. But this blog item "Elizabeth Kolbert: James Hansen Arrested" - along with Darryl Hannah at a mountaintop removal site in West Virginia - has a link to the abstract (and the whole article if you want to purchase it, or go out and buy this week's New Yorker, which they'd probably prefer!)
James Hansen is the guy the Bush administration hassled because he was trying to wake us all up. Of course it isn't convenient if big financial backers just happen to earn their money with coal. He wants to see all coal fired plants stopped entirely in 20 years, which means we'd better start now to find alternatives, and retire the dirties ASAP, so we don't suddenly find us without enough energy.
There are lots of alternative energy solutions ready to go, so it shouldn't be a problem. We just have to get a move on.
By the way, I was at a job fair today looking for a teaching job. Unfortunately some are quite a ways away. I wouldn't mind an hour or so commute if it could be done on public transportation, so I could sleep or read or grade homework during the trip, but I mentioned that to some people and they were thinking more about total time than total available time. why anyone would take a job where they sit in a freeway parking lot for an hour to get to and from is beyond my comprehension, but that's sort of how everyone does in the LA area, because public transportation does not cover the area enough, does not run often enough (and some of the trains share the tracks with freight trains, who own the track!)
