Climate change affects Arctic geopolitics and the security environment of small island states by doing what?

• A. Reducing shipping opportunities and expanding island security
• B. Opening new Arctic shipping routes and increasing resource competition, while sea-level rise threatens island security
• C. Having no impact on Arctic routes or island security
• D. Only affecting landlocked regions

Answer: (B)

The main concept is that climate change reshapes security by changing where and how threats and opportunities appear. In the Arctic, melting ice makes new shipping lanes usable and opens up access to untapped resources, which heightens competition among states over routes and seabed rights and can lead to greater militarization or strategic maneuvering. At the same time, rising sea levels threaten the very foundations of small island states—coastlines, ports, freshwater supplies, and housing—creating acute security challenges through displacement, reduced resilience, and increased exposure to storms. The best answer captures both of these dynamic effects: new Arctic shipping routes and more resource competition, alongside sea-level rise threatening island security. The other options misstate the impact—shipping opportunities are not typically reduced, the effects are not limited to landlocked regions, and the issue is not negligible or non-existent.
