You talk like this is going to happen overnight. It won't and this is not how it works. Even in the recent articles, sea level rises in MILLIMETERS, not FEET:

"Seas rose about 14 centimeters (5.5 inches) from 1900 to 2000, the new study suggests, for a rate of 1.4 millimeters per year. The current rate, according to NASA, is 3.4 millimeters per year, suggesting that sea level rise is still accelerating."
If you do the math, there's approximately 300mm in a foot. If you think its going to raise even conservatively another 2 feet, it would take close to 175 years for sea level to rise 2 feet. Not sure how old you are, but you, your kids, and your kids kids will never see the sea levels rise 2 feet. And in the event it does happen, I would hope that humanity had either solved climate change or found a suitable alternative on another planet by then.
