Actually, I think the estimate is 200 ft or 61 meters if Antartica were to melt. However, I dont believe there is really any concern there as the average temperature in Antartica is -37 degrees. In the last 100 years the earth's temperature has increased about half a degree Celsius. At that rate, its going to take quite a while before Antartica nears a temperature that can melt its ice (estimated to be about 7000 feet thick).
I also disagree that the question of whether this is even possible is not debatable. I dont know when you got your MS, but Im sure you would agree that what we "knew" to be true yesterday, may not be what we "know" today. Science is constantly progressing. 500 years ago, we thought the world was flat. 100 years ago, doctors were using leaches to treat illnesses. My point is, what was not debatable 10 years ago may very well be debatable today. There are many studies out there on this subject. For every report that says sea levels will rise dramatically over the next 100 years, there is another that says it would take fully 20,000 years to raise sea levels even a single meter.
