Melting polar ice creates a new challenge for British adventurers - Climate Change, Environment - The Independent

A team of British adventurers is about to cast off in an attempt to be the first people in the world to row a boat to the magnetic North Pole.
...
On the way they will face howling winds that, despite it being the Arctic summer, will bring temperatures down to -15C.
...
The magnetic North Pole was chosen because the ice melt makes it feasible. The geographic North Pole may also become possible if the shrinkage continues at its present rate.

Answers.com - How far away from the North Pole is the Magnetic Pole

The Earth's Magnetic North Pole, where the magnetic field lines become oriented vertically, moves constantly due to the drift in the Earth's magnetic field. In 2005, the Magnetic North Pole was located at 82.7°N by 114.4°W. To find the magnitudal 2-D land displacement (distance) from the Magnetic North Pole to the True North Pole, multiply the difference between the Magnetic North Pole's latitude (+82.7) and 90 degrees, by 60 nautical miles. (Or: [90-82.7 = 7.3] × 60 = 438 nautical miles). That value was correct for 2005, but keep in mind that any latitudinal shift in the position of the Magnetic North Poll indicates a change in distance between the two.
