The Arctic ice cap – how long has it got?
+Plus Magazine Today Pen Hadow, a world leading polar explorer and environmentalist, and Joo Rodrigues, a physicist from the Department of Applied Mathematics and Theoretical Physics at the University of Cambridge, announced an international scientific survey to determine for how much longer there will be a permanent ice cap at the North Pole.

In February 2008 an expedition, comprising Hadow, the polar explorer Ann Daniels and specialist Arctic photographer Martin Hartley, will set out on a 2000km journey from Point Barrow, Alaska, hoping to reach the geographic North Pole in June. The team will be walking in temperatures as low as -50C, and may have to swim across stretches of open water. The data collected by the team will be analysed statistically and results fed into mathematical models that scientists hope will give vital clues about the Arctic’s future.
