4,500-year-old Arctic Ice Shelves Break Up

on

CBC reports that researchers from Trent and Laval universities have recorded the break up of hundreds of square kilometres of Arctic ice shelves – some as old as 4,500 years

“These changes are irreversible under the present climate and indicate that the environmental conditions that have kept these ice shelves in balance for thousands of years are no longer present,” said Trent University professor Derek Mueller.

Hat tip to Peter M for the spot.
