Which factor most influences Arctic territorial claims and shipping routes?

• A. Melting ice that opens navigation routes and access to resources, and claims to continental shelves.
• B. Political ideology alone.
• C. Only weather patterns in winter.
• D. There is no influence on claims.

Answer: (A)

Physical changes to the Arctic environment driven by climate change shape both where shipping routes can safely operate and where states push to claim rights to the surrounding seabed. As sea ice retreats, longer windows open for nautical passage along routes like the Northern Sea Route and the Northwest Passage, reducing travel times and opening up commercial shipping. At the same time, access to underwater resources becomes more feasible, prompting states to strengthen or expand claims to the continental shelf under international law, which can extend a nation’s control over resources and sovereign rights beyond the standard 200 nautical miles. This legal and economic incentive is tied directly to the physical geography of a changing Arctic.

Political ideology alone and winter weather patterns do not determine these claims in the same way, and the idea that there is no influence ignores the clear link between environmental change, navigation potential, and legal rights to resources.
