Polar bears and climate change: What does the science say?

The image of a polar bear stranded on melting sea ice is often used as a symbol of the world’s rapidly changing climate. Yet every now and again, claims emerge in the media that polar bears’ plight might not be so serious after all.

Carbon Brief has dug through the literature on polar bears and climate change and spoken to experts from around the world to determine what a changing climate means for polar bears.

The consensus is clear – as Arctic sea ice melts, polar bears are finding it harder to hunt, mate and breed. While polar bears have shown some ability to adapt to changes in their surroundings – for example, by foraging for food on land, or swimming more to hunt for prey – scientists project that as sea ice diminishes, polar bears will find it harder to survive and populations will decline.
