Those reports found that sea ice is vital to polar bear survival and has declined dramatically in recent years. Furthermore, multiple climate models — chosen for their accuracy in describing observed declines in Arctic ice — predict that ice will continue to recede. Thin ice covering much of the Arctic Ocean is expected to melt entirely this summer, potentially leaving the North Pole free of ice, according to a projection by the National Snow and Ice Data Center posted earlier this month.
