Edgar was certain Al Gore was wrong–in fact he was part of the problem.  Yes, global warming was a man made problem, but it wasn’t industry or autos that were the cause.  The lift from rising thermals over areas where politicians spewed hot air–the White House, Congress, any Governor’s  Mansion, any State House or mayor’s offices or city council chambers–was significantly better than the hot air over any industrial area or freeway during rush hour. . . . .  David, Sf.G.
