If it melted sea levels would not be affecteÂ­d. There is a significant amount of ice covering Greenland, which would add another 7 meters (20 feet) to the oceans if it melted. Because Greenland is closer to the equator than Antarctica, the temperatures there are higher, so the ice is more likely to melt.
How is sea ice extent changing? Satellite measurements show the average annual sea ice extent in the Arctic has declined by 3.5â4.1% per decade since 1979, while summer extent has decreased by 9.4â13.6% per decade. In Antarctica the changes have been much more subtle and regionally variable.
