Polar bears found swimming miles from Alaskan coast
An aerial survey by government scientists in Alaska’s Chukchi Sea this
week found at least nine polar bears swimming in open water — with one at
least 60 miles from shore — raising concern among wildlife experts about
their survival.
Geoff York, the polar bear coordinator for WWF's Arctic Programme, said that
when polar bears swim so far from land, they could have difficulty making it
safely to shore and are at risk of drowning, particularly if a storm arises.
“To find so many polar bears at sea at one time is extremely worrisome
because it could be an indication that as the sea ice on which they live and
hunt continues to melt, many more bears may be out there facing similar
risk,” he said.
“As climate change continues to dramatically disrupt the Arctic, polar bears
and their cubs are being forced to swim longer distances to find food and
habitat.”
Scientists say the Arctic is changing more rapidly and acutely than anywhere
on the planet, noting that 2007 witnessed the lowest sea ice coverage in
recorded history.
Satellite images indicate that ice was absent in most of the region where
the bears were found on August 16, 2008, and some experts predict this
year’s sea ice loss could meet or exceed the record set last year.
The discovery of the nine bears at sea came as the US Minerals Management
Service was conducting marine surveys in the Beaufort and Chukchi Seas in
advance of potential offshore oil development.
In May, the US Department of Interior listed polar bears as threatened under
the Endangered Species Act, with Interior Secretary Dirk Kempthorne cited
the strong body of science pointing to the significant loss of Arctic sea
ice habitat as the primary reason for protecting the bear with federal
legislation.
However, the state of Alaska has opposed the listing and has sued the
federal government over its decision to list the bear.
Professor Richard Steiner of the University of Alaska’s Marine Advisory
Program said: “While these bears are swimming around in an ice-free coastal
Arctic Ocean, the only thing the State of Alaska is doing is suing the
federal government trying to overturn the listing of polar bears.
“The bottom line here is that polar bears need sea ice, sea ice is decaying,
and the bears are in very serious trouble. For any people who are still
non-believers in global warming and the impacts it is having in the Arctic,
this should answer their doubts once and for all.”
