Noble is one part science and one part smile
According to the New York Times, the Nobel committee described Al Gore as "probably the single individual who has done most to create greater worldwide understanding of the measures that need to be adopted." And if his awards would speak to that, it is a definite truth. He has won an emmy for The Channel (cable channel), two Oscars for "An Inconvenient Truth", and now the Nobel Peace Prize for his work spreading the word about global warming.
Though it seems a little rediculous that Gore would split this award with scientists who have proven what he has professed, According to the Washington Post, Gore has played the other essential part to research, publicity. The facts recorded by the International Panel on Climate Change would only have been brought to world attention through the antics of the infamous international Gore.
