If all the ice over the North Pole melted, how much would that raise the world’s average sea level?

One thought on “Calling Mr. Archimedes!”

  1. There is no change to sea level from ice melting over water. Rise in sea level is due to two factors: runoff of water from ice that melted over land (e.g., Greenland or Antarctica), and volumetric expansion of sea water due to global warming.

    Of course, the loss of sea ice dramatically changes the albedo of the Arctic region, leading to increased Arctic region sea temperatures.
