Global warming -- an optimist's view

As I keep saying when the weather is unseasonably cold here in Massachusetts: "Where is global warming when you need it?" I say this, of course, in utter jest, but there are some slight not-all-negative effects of global warming, as illustrated in this story. I'm glad the article has the decency to add: "This is all speculative, even a little facetious, and any gains are not likely to make up for predicted frightening upheavals elsewhere."
