Global warming could see most polar bears disappear from Arctic by 2100 – study

The study, published in Nature Climate Change, said “aggressive” cuts to greenhouse gas emissions are now needed to save polar bears.

Melting sea ice could “jeopardise” the survival of most of the Arctic’s polar bear population by 2100, a new study claims.

Researchers from the University of Toronto in Canada said a loss of sea ice caused by global warming will force the animals on to land, where they must rely on fat reserves due to a lack of food.
