A new report reveals a rise in polar bears on land and dangerous travel conditions in Northwest Alaska due to climate change.

The report reveals an unusual increase in polar bear presence on land in Northwest Alaska due to declining sea ice, posing challenges for human-bear interactions and travel safety, while warming temperatures and shifting seasons complicate traditional travel and hunting practices.

More reports are emerging around the world of the virus in mammals, including species found in the Arctic. Officials say there's no evidence suggesting transmission from eating infected animals which are cooked - but country food is often eaten raw.
