The North Pole Unwrapped - Russell Kane, Felicity Aston and Lloyd Peck

The episode examines the North Pole through overlapping lenses of geography, navigation, biology, and atmospheric science, with guests Felicity Aston, Lloyd Peck, and Russell Kane drawing on direct field experience. The discussion moves from precise definitions of the region to the practical difficulties of working there, the distinctive adaptations of its organisms, and the observable effects of recent environmental shifts.

Multiple poles and navigation limits

The geographic North Pole sits at 90 degrees north on the rotating Earth, while the magnetic North Pole marks the end of the planet’s magnetic field and currently drifts toward Siberia at roughly 50 to 70 kilometres per year. The geomagnetic pole, a theoretical construct used in models, remains fixed. These distinctions matter for travellers: a compass points to the magnetic pole rather than the geographic target, and the angular difference (declination) changes with location and time. Ice drift further complicates position-keeping. Hand-held GPS units lose battery life quickly at minus 40 degrees Celsius, and sextant observations fail under persistent cloud. Explorers therefore combine methods, accepting that small errors and ice motion will often determine the final approach.
