A new study finds that an area of the Arctic Ocean critical for the survival of polar bears is fast becoming vulnerable to climate change.
The region, dubbed the "last ice area" had been expected to stay frozen far longer than other parts of the Arctic.
But this new analysis says that this area suffered record melting last summer.
The researchers say that high winds allied to a changing climate were behind the unexpected decline.
The Wandel Sea area, to the north of Greenland, is part of what scientists call the "last ice area".
Normally, this region retains thick, multi-year ice all year round.
