Answer: You must only consider the ice on Greenland and Antarctica, as the rest is simply floating on the water and won’t make a difference. Work out the area of Greenland and Antarctica with an assumption that the ice is 6000ft deep – and the answer to the question is 240ft higher and would cover most of the world’s capitals.
