The Arctic is warming more than twice as fast as the rest of the planet, because as ice melts at the top of the world, there is less of it to reflect sunlight back into space, so more of it is absorbed by ocean waters; more absorbed sunlight means even warmer temperatures, which means more ice melt a circular process known as Arctic amplification.

And the more that sea ice melts, the more energy is absorbed — a positive feedback mechanism of accelerating warming and ice loss, he said.

The underlying logic is sound: as sea ice melts, it exposes darker ocean water, which absorbs more of the sun's heat, causing the water temperatures to increase.

And the more quickly the ice melts, the darker it gets — causing even more melting.

The shrinking sea ice drives a classic positive feedback loop: as more ice melts, fewer patches of white snow reflect solar energy, and larger regions of dark, sunlight - absorbing seawater open up — both causing the ice to melt even faster.
