The United States has its climate change personality – Bill Nye, “the Science Guy”.  CBC has Nye’s equivalent in Bob Mcdonald, a science journalist who for years has been the host of  the radio program “Quirks and Quarks”.

From time to time McDonald has been interviewed on The National, the CBC new flagship.  Last night (Friday November 3d), Bob appeared  on the National and answered questions on Climate Change submitted by CBC viewers  .  Heather Hiscocks read the questions and elaborated on Bob’s responses.
