Global warming is local: The Morning After (Chicago edition)

The couple of hundred yards of ice that was forming along our Lake Michigan shore yesterday has disappeared, due doubtless to shifting currents and wind direction. The water underneath was about 33o Fahrenheit today, and the air in our neighborhood was reported by the weather service to be about -11o (-24o Celsius). For the record it's now warmed up to -10o. The photo, taken from my dining room window shortly after sunup this morning, shows how that temperature differential causes clouds of surface steam. Amazing and beautiful.
