[Delta 21]

"The mass of the ice sheet depresses the mantel below it, so that the bottom is below sea level. As it melts, the mantel will rise, causing the bulk of sheet to be above sea level and slide into the ocean, raising sea level about 10 feet over the next 200-1000 years."

Do you have a PhD also?
