“Scientists stress, however, that because the trillion-ton iceberg is already afloat in the Weddell Sea, its detachment does not raise the globe’s sea level.” It is important to understand that once ice is afloat, it already displaces its weight in seawater, as if it was already melted. This makes it clear that even if all the entire Arctic Ice Pack over the North Pole, and all the floating sea-ice surrounding Antarctica were to melt, it would make no difference to global sea-levels: For the sea to rise, ice that is on land in Antarctica and Greenland would have to melt and run into the sea. That will happen very slowly over thousands of years, at an average rate of 2mm per year. Nothing to worry about there: if the human race can’t survive a 20cm (8") rise per Century, there’s something wrong with us.
