The plight of the polar bear has become as a cliché of the climate change debate. Those advocating serious steps to ease global warming have probably over-exposed the bears as symbols for their cause. Skeptics scoff, and some Inuit hunters too. But not much has been said about how to save the bears if (as the overwhelming scientific evidence so strongly suggests) the Arctic ice is dwindling. Now, two university researchers propose a practical, partial solution: protect the remaining habitat. That sanctuary would include parts of Canada and Greenland where the ice is thickest and likely to last until at least 2100, by which time most of the Artic will probably has been ice-free year-round for several decades.
