Why is the Arctic warming significantly faster than the global average?

Multiple studies and reports have shown that the Arctic is warming much faster than the rest of the planet. Why is this occurring?

The Arctic is warming faster because of the ice-albedo feedback.  A large area of the Arctic is covered by snow and ice, surfaces with a high albedo.  That high albedo reflects a high percentage of incoming sunlight, and thus the ground doesn't absorb as much energy.  As the snow and ice melts due to warming, darker ground and ocean is exposed, surfaces with a much lower albedo.  That lower albedo allows the ground and surface ocean to absorb insolation, causing the surface in the Arctic to get warmer.  As that surface warms, it melts even more snow and ice, exposing more dark ground/ocean, heating up even more, etc.  It's a positive feedback loop.  Lower-latitude locations don't have the ice-albedo feedback effect, and thus aren't warming as fast.
