Adventurer and naturalist Steve Backshall is on a mission to visit parts of the world yet to be explored.

On this expedition, he is in the Arctic to kayak up the largest fjord in the world. It is a dangerous undertaking, only made possible because the sea ice has broken up early here following the warmest winter on record. It is a chance for Steve and his team of explorers to see what impact global warming could be having on this pristine wilderness. They face many threats, from perilous sea ice that could crush their boats to a terrifying encounter with a hungry polar bear. Show less
