That's because the continued increase of average temperatures around the world is causing the patches of sea ice that polar bears and other arctic creatures once called home to become more and ...

The farther the bears have to travel to get on the ice to hunt ... a recent study published in Polar Biology found. “As the sea ice melts earlier and earlier, polar bears are forced to swim ...

For centuries, sea ice was deemed essential for polar bears to survive. Generations of the Arctic bears ventured onto the slabs of floating ice to travel long distances and prey on unsuspecting seals.

While polar bears are strong swimmers, sea ice is essential for travel, because it takes a lot of energy to move their bodies through the water. “Swimming has been found to be five times as ...

By Henry Fountain Scientists have identified a distinct subpopulation of polar bears in southeastern Greenland that, in an area with little sea ice, survive by hunting from ice that breaks off ...

Global warming continues to trigger the mass melting of Arctic sea ice, causing polar bears to begin gravitating toward land, scientists from Polar Bears International told ABC News. Sometimes ...

Three adult polar bears travel across sea ice in eastern Greenland. Environments in the Far North that would have stayed well below freezing now experience freeze-thaw cycles and wet snow due to a ...

Scientists have long hypothesized what would happen to polar bear populations in the Arctic as sea ice continues to melt at unprecedented rates. But now they have visual evidence of just how hard ...

As sea ice declines, more polar bears spend more time on land ... the changing climate has led to more difficult and dangerous travel, and, as a result, postponed activities and altered hunting ...

University of Toronto Scarborough researchers have directly linked population decline in polar bears living in Western Hudson Bay to shrinking sea ice caused by climate change. The researchers ...

Sea ice extent is at ... a historic holdout of year-round ice. Dubbed the “last ice area,” this frozen stronghold is home to iconic Arctic wildlife: polar bears, beluga whales and ringed ...

Polar bears survive by hunting on sea ice, which makes them especially vulnerable to climate change. New research shows that sea ice loss can present other, less obvious threats to the species as ...
