Polar bear sightings are increasing at Arctic landfills around the world.
As climate change diminishes Arctic sea ice, polar bears are being forced to ransack towns and garbage dumps in ever greater numbers, a new study in the journal Oryx finds.
In the new study, the researchers described six case studies that showed above-average polar bear encounters with Arctic communities in the United States, Canada and Russia. In each town or community, the number of polar bear sightings has increased steadily over the past several years or decades, leading to some dicey situations.
It's likely that human-made climate change is at least partially responsible for the increase in human-polar bear interactions, the study authors wrote.
