About this Video
Permafrost is an underground layer of soil or rock that stays frozen all year round, but in recent years it's been thawing. In some parts of the north the thaw has created sinkholes and is disrupting the natural order of life. The full force of climate change is visible at Polar Bear Provincial Park in Ontario's far north.
