Polar bears: An uncertain future

The great white bears of the frozen north may face a difficult future. Each summer, the sea ice on which they rely to hunt seals is getting thinner and smaller in extent - threatening to upset their way of life.

Here, American photographer and conservationist Jenny E Ross - and Andrew Derocher, professor of biological sciences at the University of Alberta - give their opinions on how climate change is affecting the lives of polar bears, and potentially putting their future at risk.
