If the polar icecaps melt, which part of britain will remain above water?
All of Britain will remain above water. If the ice caps melt there would be no discernable rise in water level. While the ice caps are large, the open sea is far greater and would simply level out the excess water. Remember also that the ice caps are displacing vast volumes of water, so when the ice melts it takes up the space vacated by the ice, infact, as water expands when it turns to ice then when it melts it will take more water to fill the displaced volume.
