In a single year, the Arctic lost an area the size of Alaska. So how long before it melts altogether? Juliette Jowit meets the British explorers risking their lives to find out
On a cold Monday in December, one of Britain's most experienced polar explorers is sitting in an even colder room in Portsmouth, explaining his latest mission. The temperature has been turned down to a mere -20C, tropical by comparison to the almost inconceivable conditions he will have to endure during his next expedition to the Arctic. There, temperatures can drop as low as -90C; it is dark all day or the sun can blind people in minutes; the explorers will wake up, their eyelashes frozen together, in sleeping bags full of shards of ice; the ground beneath the trekkers' feet will be only inches of frozen water which can at any moment open into icy rivers which will kill almost instantly, and, apart from the odd grey seal, the only life they are likely to meet is a hungry polar bear.Meeting Pen Hadow for the first time is something of a shock. He is the first man in history to have managed one of the ultimate feats of human endurance - to trek solo and unaided to the North Pole. But instead of the great strapping giant of a man you might expect, the 46-year-old is slightly built, and his hand, when he shakes mine hello, is almost the hand of a woman. As Hadow talks his breath frosts the air in front of his face, but he looks unperturbed while sitting still in this giant concrete freezer. Such small extremities, along with his brown eyes, olive skin and naturally low heart rate, make him ideally suited to a life of spending months at a time alone or responsible for teams of amateurs in one of the most inhospitable environments on earth.
