As the climate crisis worsens, some animals are in danger of becoming extinct. The polar bear is perhaps the most well-known case.
With less sea ice, the polar bears are having fewer cubs and are becoming thinner.
But there is an "isolated population of polar bears from southeastern Greenland that is much less reliant on sea ice" according to an article posted on Science.
These polar bears live at the end of a glacier and rely on resources from this glacial freshwater.
Polar bears typically hunt seals but are known to consume larger prey.
Polar bears are in grave danger as climate change continues to threaten their habitat. The U.S. Geological Survey projects that two-thirds of polar bears will disappear by 2050 and some predict extinction by the year 2100.
