In The Eagle's Opinion Line Extra, someone recently asked, "Hey, Al Gore — how's the global warming gig working out?" Last week, as much of the nation was dealing with a historic snowfall, the former vice president countered criticism that such storms are evidence against man-made global warming. "Here's a basic fact," he said. "There is about 4 percent more water vapor in the atmosphere today than there was in 1970" — moisture, caused by warmer oceans and air, that is turning into big, heavy snow and rain, he said. On his blog, he wrote: "The scientific community has been addressing this particular question for some time now and they say that increased heavy snowfalls are completely consistent with what they have been predicting as a consequence of man-made global warming."
