I don't mean to unduly upset anyone not already concerned about climate change, and I know that as scientific evidence it's merely anecdotal, but tonight while I was sitting in front of an open window checking my email I was buzzed by a mosquito. And on the roof garden just beyond the sill our large begonia bush, like all of the other plants not cleaned out of the pots last fall, seems to be thriving.

The place: Manhattan. The date: January 6.
