(Keep in mind that almost all Arctic sea ice researchers add a big caveat when talking of an «ice - free Arctic Ocean,» noting that a big region of thick floes north and west of Greenland will almost surely persist in summers through this century, which is one reason some scientists have proposed targeting polar bear conservation efforts there.)

The fate of sea ice in the Arctic Ocean is determined by a complicated mix of factors, including the pressure changes, with the biggest loss of old thick ice resulting more from a great «flush» of floes than melting, Dr. Rigor and many other scientists tracking the region say.
