As Polar Bear Numbers Continue To Increase, GWPF
Calls For Re-assessment Of Endangered Species Status
On the occasion of International Polar Bear Day, the Global Warming Policy Foundation (GWPF) is calling on the U.S. Administration to re-assess the ‘endangered species’ status of polar bears.
On May 15, 2008, the U.S Fish and Wildlife Service listed the polar bear as threatened under the Endangered Species Act. The listing is based on the assumption that loss of sea ice threatens and will likely continue to threaten polar bear habitat.
In a GWPF video released today, Dr Susan Crockford, a Canadian wildlife expert, documents the latest findings about rising polar bear numbers.
In 2005, the official global polar bear estimate was about 22,500.
Since 2005, however, the estimated global polar bear population has risen by more than 30% to about 30,000 bears, far and away the highest estimate in more than 50 years.
A growing number of observational studies have documented that polar bears are thriving, despite shrinking summer sea ice.
By September 2007 sea ice extent was about 43% less than it had been in 1979 – a decline not expected until mid-century, and every year after was almost as low, or lower.
Yet no more drowned polar bears were documented, no more bears than normal starved to death, no unusual spikes in cannibalism occurred, and not a single polar bear population was wiped out.
New scientific evidence suggests that loss of summer sea ice, regardless of the cause, is not a major risk for polar bear survival.
“A thorough external review of the polar bear status issue is now required - not only because it’s the right thing to do but because it may help restore public support for science and conservation,” Dr Crockford said.
