Canada has moved to protect the region, where Arctic wildlife is expected to make its last stand against climate change. Scientists say it's not enough.

...most of the North Poles year-round sea ice will be lost by the end of this centurysave for one final refuge known as the Last Ice Area. Arctic animals that are dependent on sea ice are expected to make a last stand in this region, which is why the Canadian government recently granted protected status to large portions of it.
This narrow band of thick ice encompasses about a million square kilometers flanking the Northern coasts of Greenland and the Canadian Arctic Archipelago. The Canadian branch of the World Wildlife Fund coined its popular name, but the general contours of the area were first defined in 2010 by a team of scientists that included Stephanie Pfirman, an expert in Arctic sea ice dynamics at Arizona State University. The wind and ocean currents transport ice across the Arctic to this region, so by the time it accumulates here, it is old and ridged and therefore thicker than ice in other regions, Pfirman explained in an email. This means that it takes longer to melt.
The results of a business as usual scenario in which greenhouse gas emissions continue at the current rate will be much more dire, however, according to the models. Under the business as usual assumption, you do eventually lose even the Last Ice Area... It is a bleak contrast in possible futures for this polar haven. As the Arctic warms over the coming decades, animals that depend on the sea ice habitatsuch as polar bears, walruses, and eiderswill retreat to the Last Ice Areas borders to survive. Nobody knows how well they will fare within its confines...It is a race against timewe will need more than just switching away from carbon-based energy sources, we also need to sequester carbon in order to quickly slow the warming, she noted. Otherwise the last ice will be lost in summer along with the devastation of the ice-dependent ecosystem that we're trying to protect.
