Dam it: beavers head north to the Arctic as tundra continues to heat up

Dammed rivers could accelerate climate crisis as creatures move into previously inhospitable areas

The transformation of the rapidly warming Arctic is being accelerated by a wave of thousands of newcomers that are waddling and paddling northwards: beavers.

Scientists who sought to map the spread of beavers in Alaska were astounded to find that the creatures have pushed far north into previously inhospitable territory and are now set to sweep into the furthest northern extremities as the Arctic tundra continues to heat up due to the climate crisis.
