:sorry1: Antarctica is a land mass. It is covered by ice, often kilometers thick, but underneath it is soil. In this map, the grey is where the ice sticks out into the ocean, while the white is where the ice covers the soil.
The NORTH pole (the Arctic) there is no landmass. That is why it is so much worse to have Antarctica and Greenland melt. Melting the acrtic is bad for multiple reasons, but like melting an ice cube in a cup of water, it doesn't make the total water level rise. . Melting Antarctica and Greenland means dumping all that landlocked water into the sea. ("blub blub" goes Florida and Denmark).
A good friend of mine works for 6 months in Antarctica during its warmer season, and he says that if anyone if anyone saw what he has seen over the last dozen years that he's worked down there, they wouldn't even have to think twice about whether global warming is taking place.
