Short summary
The navigability of the Arctic Ocean is increasing with the warming in recent years. Using model simulations at a much finer resolution than previous pan-Arctic studies, the impact of marine shipping emissions on air pollution in the Canadian Arctic is assessed for present (2010) and projected levels in 2030. The study found that shipping emissions have a local-to-regional impact in the Arctic at the current level; the impact will increase significantly in a projected business-as-usual scenario.
