Missing News: Arctic Ice Melt not unprecedented

Yet another story missing for over 2 years....
According to the Geological Survey of Norway.....
Recent mapping of a number of raised beach ridges on the north coast of Greenland suggests that the ice cover in the Arctic Ocean was greatly reduced some 6000-7000 years ago. The Arctic Ocean may have been periodically ice free.
”The beach ridges which we have had dated to about 6000-7000 years ago were shaped by wave activity,” says Astrid LysÃ¥. They are located at the mouth of Independence Fjord in North Greenland, on an open, flat plain facing directly onto the Arctic Ocean. Today, drift ice forms a continuous cover from the land here.
Astrid Lyså says that such old beach formations require that the sea all the way to the North Pole was periodically ice free for a long time.

Wonder if ABC Science will provide any coverage.
