So apparently Lake Superior is a meter below it’s annual average this year, according to this CBC Radio piece. (WMV link. Start listening about 15:30.) Given that we’re talking about the largest source of freshwater in the world, that’s enough water, the piece says, to keep Canada slaked for a decade. And it’s going away.

Have I mentioned there’s a really dumb idea out there to send water from the Great Lakes to the American Southwest? Any chance I’ll be able to win my ecology back at the blackjack tables in Vegas?
