My colleague, Dr. Schaff, notes below the topic of Al Gore and Global Warming. Ron Bailey at Reason has this on Gore's New Movie.
I have long been a critic of former Vice-President Al Gore, but as a recent convert to the view that humanity is contributing significantly to the current increase in average global temperatures, I was trying to keep a somewhat open mind about his new global warming movie, An Inconvenient Truth. . . .
Gore claims to be presenting the "scientific consensus" on global warming. But is that so?
Well, at least not always. Take sea level rise for example. Gore spends a lot of time talking about how dramatic melting of the Antarctic and Greenland ice caps that could raise sea level by 20 feet by 2100. He shows computer animated maps in which most of southern Florida, southern Manhattan, Shanghai, and Bangladesh are inundated. "Think of the impact of a couple hundred thousand refugees, and then imagine 100 million," says Gore. Of course his reference to the couple of hundred thousand refugees aims to evoke thoughts about the horrific experience of New Orleanians last year.
Well, the "consensus" of climate scientists as represented in the United Nations' Intergovernmental Panel on Climate Change is that sea level is likely to rise between 4 inches to 35 inches with a central value of 19 inches. Nineteen inches is not nothing and is 3 times greater than the sea level rise the world experienced during the 20th century, but Manhattan and most of Florida will most likely still be above water in 2100. A new study in Science concluded if temperatures rose steeply that the Greenland ice sheet might melt away in 500 to 1000 years. So fortunately we don't have to worry about the impact of 100 million people fleeing relentlessly rising seas all at once, though it would be a good idea for builders and insurance companies to keep the projected rise in sea level in mind.
Read the whole thing, but that passage its pretty good indicator of how honest Honest Al is in this film.
