Who's Afraid of a Little Water?

During Al Gore's testimony before a congressional committee today about the 'moral imperative' of passing a climate bill, he mentioned his fears that the sea levels will rise:

Mr. Gore spoke of ice melting at both poles. Just the collapse of the Western Antarctic Shelf, he said, could raise global sea levels by 20 feet. By his calculation, that would lead to about 600 million “climate refugees.”

But apparently Al's not too afraid of becoming one of those 600 million refugees. In 2005, the same year his "Inconvenient Truth" movie came out, Al purchased a $4 million apartment in the St. Regis Tower in San Francisco. The satellite photo above shows the distance from his apartment to San Francisco Bay: Less than one mile.

So Al, when the ocean rises by 20 feet, how do you plan to get in and out of your apartment? Is there a helicopter pad on the roof?
