 NEW YORK (AP) - Al Gore has taken some heat lately for spreading the word about global warming.
First there were the allegations by a conservative group, the day after Gore collected an Oscar for his movie "An Inconvenient Truth," that his Nashville mansion consumes more than 20 times as much electricity as the average American household. Then there were charges that zinc mining on Tennessee property owned by Gore tarnished his environmentalist credentials.
By the time he arrived on Capitol Hill this past week to testify about his signature issue, the barbs Gore's congressional adversaries hurled at him sounded relatively benign.
