Polar Bears Losing Weight as Arctic Sea Ice Melts, Canadian Study Finds

Three decades of melting sea ice has led to significant weight loss among the world’s southernmost population of polar bears, new data from Canadian researchers suggests.

“It’s a red flag,” said Martyn Obbard, a scientist with the Ontario provincial government and co-author of a recently published study in the journal Arctic Science.

Researchers looked at a population of about 950 polar bears who live along the northern coast of Ontario, stretching from James Bay to the provincial border with Manitoba. As they live further south than any other population of polar bears, the group is particularly vulnerable to the effects of climate change.
