Predictions about devastating declines in polar bear populations, they say, have failed to materialize.

In effect, many scientists say, the bears have been co-opted by climate denialists, and in an article published Tuesday in the peer-reviewed journal Bio Science, 14 prominent researchers argue that denialist blogs with wide followings are using the bears to spread misinformation about the causes and consequences of climate change.

Crockford’s blog, the article noted that she has no demonstrated expertise in climate science or its effects on polar bears.

The credentials of many of the Bio Science paper’s authors include long lists of published, peer-reviewed articles and studies on these subjects. Crockford is an adjunct professor in anthropology at the University of Victoria in British Columbia.

Polar bears, the charismatic icon of the Arctic environment, have long been a focus in WWF’s on-the-ground research and conservation projects in the Arctic, going back to 1972 – and climate change is a primary focus of our global conservation efforts.

WWF accepts that it is unreasonable to designate the whole Arctic as a place of no industrial activity.

Keeping polar bears separate from people is better for both—as polar bears that wander into communities pose a risk to people, and people often respond by killing the bears.

WWF has responded with a variety of locally-led initiatives to help reduce conflict.

But at a time when established climate science is being questioned at the highest levels of government, climate denialists are turning the charismatic bears to their own uses, capitalizing on their symbolic heft to spread doubts about the threat of global warming.

The scientific evidence that the polar bear’s Arctic home is warming twice as fast as the rest of the planet is overwhelming, supported by reports like the National Climate Assessment, which was compiled by 13 federal agencies.
