Global warming warps Arctic wildlife | News – The Times
The Arctic Ocean may be changing faster than any other sea, with global warming causing surges in killer whales and salmon but threatening polar bears and seals, scientists have said.
The decline in sea ice and shifts in currents are causing profound changes in the mix of animals in the Arctic and Inuit communities are being forced to adapt, according to an assessment by the Canadian government.
The decline of some populations of polar bears, which use sea ice as a hunting platform, has been well documented but the report says that other species are taking advantage of ice-free seas.
There has been an “almost exponential increase” in the number of killer whales in Hudson Bay in recent decades, potentially forcing narwhals and bowhead whales
