An isolated group of polar bears living in southeast Greenland has surprised scientists with its ability to survive in a habitat with relatively little sea ice.

From temperatures sometimes plummeting to below minus 30 (-34.4 Celsius), to polar bears and arctic foxes occasionally roaming local streets, it takes a unique individual to forgo life on the ...
The key danger for polar bears posed by the effects of climate change is malnutrition or starvation due to habitat loss.Polar bears hunt seals from a platform of sea ice.
