WATERLOO, Ontario — As a nonnative speaker of English, I have always been intrigued by the phrase "polar opposites." Fact is, nothing so resembles the North Pole as the South Pole. Based on this polar symmetry, there exist the opportunity and an increasingly urgent need to emulate Antarctica and establish an Arctic nuclear-free zone. Such a step would have significant environmental and conservation benefits, while working to avoid conflict and foster scientific cooperation.
The urgency of the need arises from the existing unsatisfactory legal situation on territoriality, military practices and the faster-than-expected rate of Arctic ice cap shrinkage. Global warming is opening up the prospect of navigating the sea surface of the Northwest Passage linking the Atlantic and Pacific oceans, and the potential for military clashes.
Recently there has been a flurry of declarations (for example, by Canada), activities (by Russia) and counter-responses from others that use the Arctic perimeter or its waterways for their navies.
