This afternoon I went cross country skiing with Will Steger! We have some mutual friends, and one of them (thanks, Michelle) invited me to join him and her for a jaunt around beautiful O'Brien State Park. I normally don't ski when it's this cold (it was about ten degrees and windy), but you don't get an opportunity like this every day. And you don't complain about the cold around a guy who's spent much of his adult life camping in the arctic. Notice how he's not only taken off his jacket, but has got his sweater unzipped to the waist. On his hands he was wearing only thin glove liners.
If you've got any doubt that global climate change is real, check out some of Will's writings. Over the last 45 years he's borne witness to alarmingly rapid arctic melting, documenting what he's seen in his quiet, gentle, matter-of-fact manner. He told me that one of the main things he's trying to do is stop all the fighting over the matter; it's happening, so what are we going to do about it?
Update, January 25th: The New York Times just did an interesting piece on what seems to be happening with our climate/weather.
