Now, I know about all the hoopla concerning the polar bears, but I also just read that they're moving south. In other words, if their habitat is ice that's going away, they're simply adapting - not going extinct.
Like I said, I don't buy the apocalyptic stories. Nobody in that camp seems to take into consideration what a breadbasket Canada and Siberia would become with a longer growing season - just as an example.

For information on sea ice, see Cryosphere Today,
http://arctic.atmos.uiuc.edu/cryosphere/ The greatest extent of arctic polar ice recorded was 1n 1979 at 15M sq kilometers. Last year's peak was 13.5M sq kilometers.
The total extent of sea ice has not changed in the last thirty years. Yes, icebergs are caving from Greenland and the Ross ice shelf. They have for centuries. It was an iceberg that originated in Greenland that sunk the Titanic.
