Tom Brokaw let his personal environmentalism override his journalistic ethics yesterday as he interviewed Al Gore as the host of Meet the Press. Softball questions left and right, but mostly left.  Just so he could claim he was “fair and balanced” he brought up Gore’s 10,000 square foot house and his use of private planes.  Of course, the sources he cited were environmentalists to the left of Gore.  Brokaw let Gore get away with blaming the fires in California, the floods in the Midwest, and the drought in the East on global warming.  He also failed to challenge him on the statement that 8 of the warmest years of the last 100 years have been in last 10 years.  We should not blame Brokaw, he believes these to be true.  Brokaw signaled his position by stating that everyone believes the earth is warming the only question is the speed.  A perfect lead in for Gore to declare that warming is accelerating and will more catastrophic than previously believed.
