Watching the Tom Foley escapade unravel the Republicans as their stitchwork elsewhere submerges Iraq under bloody waves of civil war is bad enough. Worse, ultimately, as harbingers go, my beloved New Hampshire autumn feels tropical this year. It seems the entire world just can’t cool off. The Dust Bowl of the Tens (remember the Dust Bowl of the Thirties?) is tightening its climatological grip on America’s breadbasket. Global Warming. Relatives of mine just moved to Arizona. I don’t know what to think. If glaciers worldwide are melting, and snow pack is dwindling just about everywhere, the Sierra’s can’t be far behind. The Canadians, who have the largest supply of good fresh water in the world, are already passing laws preventing the US from getting any of it.
