These polar bears look ready for a swim -- but there is more to the story.
While this footage is stunning, its message is quite somber. Eventually, the bears reach land, but do not find ice. There's a reason for this. Polar bears need sea ice to hunt seals -- but, because of climate change, this ice is melting.
This may have drastic consequences for the future of the species, who are currently listed as vulnerable on the IUCN's Red List of Threatened Species.
"Due to their long generation time and the current greater speed of global warming, it seems unlikely that polar bear will be able to adapt to the current warming trend in the Arctic," the IUCN explains.
If climatic trends continue, polar bears face a significant population decline this century.
