The Canadian Arctic Archipelago, as a defining landscape of the Canadian persona, quickly becomes a flash point when international politics are at issue. The effects of climate change on the archipelago are no exception to this rule. The Canadian Arctic as a whole is experiencing a warming trend as a result of climate change. The political interest of this trend lies in what Canada could lose if the ice of the archipelago disappears. Canada has met some opposition to its historical claim over the land, water, and ice of the Canadian Arctic Archipelago, particularly over the Northwest Passage and mostly from the United States. The debate surrounding Canadian sovereignty in the Arctic is not new, but as a result of climate change and the consequent warming of the Canadian Arctic, it has gained new vigor. This debate typically centers on three primary components: melting Canadian Arctic ice, increased international shipping via the Northwest Passage as ice cover decreases, and the threat to Canadian sovereignty implied by increased international shipping.A sense of alarm over melting Arctic ice tends to cloud the real issues affecting the archipelago, leaving society under the impression that sovereignty is indeed in danger. Warming does indeed imply the melting of ice (in general), but melting ice does not mean no ice, nor does it mean increased shipping. Often those who predict an icereduced or ice-free Northwest Passage tend to oversimplify the nature of the ice regimes in the archipelago, thus exaggerating the potential for increased shipping and the implied threat to Canadian sovereignty.The fact that Canadian Arctic ice is melting is not in contention-it's the rate at which ice is melting and what melting ice means for the future of the Northwest Passage that ignite controversy. According to Huebert (2003), data from satellite imagery suggest that the rate of melt in the Canadian Arctic is greater than previously expected and is accelerating. These data, however, are not representative of the conditions present in the Northwest Passage, as they fail to account for the icebergs that meander southward from the Arctic Ocean into the lower reaches of the archipelago, where they block passages and create choke points. Despite the overall archipelagic warming trend, the Canadian Ice Service has not changed the definitions set in 1971 for the zone-date system, which organizes Arctic waters into sections based on a ship's ability to navigate during a specified period (Griffiths, 2004). This fact suggests that despite the Arctic warming trend, and despite the reduced ice cover throughout the archipelago's channels, conditions for navigation remain hazardous, and while different, they are not easier than the conditions existing in 1971. Otherwise, Transport Canada would update the Canadian Ice Service definitions to reflect improved navigation. In addition, ice melt patterns are not uniform throughout the archipelago, so prospective shippers face considerable uncertainty. For example, ice in the eastern Arctic is meltin...
