Here's an interesting geoengineering story in the June 2 issue of the Economist. (I wrote this essay defending geoengineering research for the December '06 issue of Wired.) The latest piece is cool, although I would by lying if I claimed to fully understand how all that CO2 would get carried into space; something to do with the same atmospheric phenomenon that causes auroras in the night sky.
Bouncing over to some entertaining southpaw minutiae, my wife's colleague pointed us toward Mollydooker Wines in Edwardstown, South Australia. I'd heard that 'mollydooker' is an Aussie term for left-hander, but I didn't know there were special wines for southpaws other than Sinister Hand, produced by Owen Roe here in Oregon.
