Here’s a notable statement from the global warming debate on “Larry King Live” last night. CNN weathercaster Rob Marciano sounded humble: “You know, as weather forecasters, we can’t get the five-day forecast right. We’re going to bank — put all of the money in the bank on a 50 or 100-year forecast, that is probably the thing that’s most concerning, especially to meteorologist that forecast on a daily basis. You know how difficult it is to do that.”

It’s quite a difference from the screen graphic under ABC weathercaster Sam Champion yesterday: “Will Billions Die From Global Warming?” Champion’s betting all his marbles on the United Nations consensus.
