Global climate change has catapulted the Arctic into the centre of geopolitics, as melting Arctic ice transforms the region from one of primarily scientific interest into a maelstrom of competing commercial, national security and environmental concerns, with profound implications for the international legal and political system. The significance of an Arctic rendered increasingly accessible by the melting of ice as a result of rising global temperatures should not be underestimated. As the region opens to increased human activity such as traffic from commercial shipping, tourism, and oil and gas exploration, soot emitted by maritime vessels and operations will land on the ice. Greying of the icecap, as black carbon from incomplete hydrocarbon combustion lodges itself in snow and ice, causes what was once a reflective surface to absorb more sunlight, melt, and warm the water. The resulting dangerous feedback loop is part of an alarming phenomenon that is pushing the current drive for policies to slow down climate change.
