A low lying sand island yes, a whole continent, I doubt it.

Its more complicated than that. As ice melts it contributes more volume to the oceans, not an issue with the North Pole, but a net +ve contribution from Antactica and Greenland. As the oceans warm, they expand which will cause further flooding. However, the flooding is not a particulalrly serious issue unless you are in low areas. If the northern Permafrost melts, thats probably it folks. The amount of Methane that will be released will be mind blowing.
