Tucked away at the top of the Earth, the Arctic plays a central role in stabilizing the global climate through the polar vortex and reflection of the sun’s heat back into the atmosphere, among other key mechanisms. The current rapid loss of Arctic sea ice is not only an urgent climate matter but a key national security matter, as geopolitical conflict will result over newly accessible resources, shipping lanes, and seabed rights. Action or inaction by individuals, corporations, and governments will determine the fate of the Arctic and, by extension, our planet and next generations.
