The Greenland ice sheet has shrunk by about 20 percent since the late 1970s, coinciding with dropping salt levels in the North Atlantic.

It is estimated that if all the Greenland ice were to melt, worldwide sea levels would rise more than 20 feet

Have worldwide sea levels really risen by 5 feet in recent decades?

Since the end of the Ice Age (18,000 years ago), Earth's temperature has risen approximately 16 degrees F and sea levels have risen a total of 300 feet ! Forests have returned where once there was only ice.

"Have worldwide sea levels really risen by 5 feet in recent decades?"

No.

I'm guessing the "20%" refers to a reduction in land area covered, not ice volume. Anyone know for sure?
