North Pole explorers on thin ice as climate change hits expedition

Mike Horn and Borge Ousland are crossing the Arctic on skis but ice drift has set them back

It was supposed to be an epic 1,000-mile journey taking in the stunning snow-covered scenery of the North Pole as two adventurers embarked on a brave bid to cross the frozen Arctic Ocean on skis.

But the experienced explorers' attempt has, quite literally, been left on thin ice as the pair struggle to navigate the harsh terrain in time - leaving them in a "touch and go" position to finish before food runs out in 12 days.
