It isn't just the polar bears that are having the ice pulled out from under their feet.
Arctic melting due to global warming is also undermining the human way of life in the far north, says a team about to embark on a 1,200-mile (1,930-kilometer) dogsled expedition.
The Global Warming 101 project, led by U.S. polar explorer Will Steger, aims to highlight how the traditional world of native Inuit communities is quite literally breaking apart.
The four-month expedition is due to set off tomorrow across Baffin Island in the Canadian province of Nunavut.
Among Steger's team will be U.K. business tycoon Sir Richard Branson and three Inuit hunters, who will guide the sleds.
