Last night I got to my hotel - the quaint Emerson Inn by the Sea -- in Rockport, Mass, after a dinner meeting in nearby Gloucester. I was tired but clicked the TV on. Jon Stewart's Daily Show turned into the Colbert Report. I don't get to watch it very often, and was fading off to sleep. But his opening segment "The Word -- Sink or Swim" was on climate change -- in fact Sea Level Rise.
