What?
Ice that is covering ground that is above sea level has the effect of raising the sea level when it melts. Greenland and Antarctica have a lot of this. Given the comparative size of the ice packs to the world's oceans and the difference in volume in frozen versus liquid water, they would have to melt an average of 37' in depth to raise the oceans 1'.
Greenland appears to be losing an ever so slight amount of ice volume, while Antarctic is gaining ice.
Duh!
