Are there fewer polar bears

More Videos Polar bear spotted in city, miles from home A polar bear was spray-painted with graffiti. Experts fear it won't survive. The bears rely on sea ice for nearly every aspect of their survival: It's where they hunt seals, travel, make dens and mate.

So the earlier in the season the ice begins to melt , the less time they have to eat and procreate. The findings were outlined in a new study published in Ecological Applications.

Researchers found polar bears are becoming thinner and having fewer cubs, and their declining health was tied to melting sea ice. Sea ice in the Arctic Ocean is shrinking fast. But what does that look like? Pictured: Climate journalist and adventurer Bernice Notenboom negotiating sea ice in the Arctic, photographed by Martin Hartley in Hide Caption.

We do know that some of the 19 polar bear populations are stable, some may be growing and others are declining, with recent losses of up to 50 per cent. Climate change is causing significant changes in sea ice extent, condition and duration throughout the Arctic.

Polar bears need sea ice to hunt seals, and these reductions are leading to fewer cub births and reduced survival rates. This work is licensed under a Creative Commons Attribution 4.
