Arctic Death Spiral: New local shipping and drilling pollution may speed up polar warming and ice melting
We’ve known for a long time about basic polar amplification. Warming melts highly reflective white ice and snow, which is replaced by the dark blue sea or dark land, both of which absorb far more sunlight and hence far more solar energy. More recently another insidious feedback has become obvious — as the Arctic ice retreats, big oil companies can drill for more fossil fuels whose combustion will accelerate warming and ice retreat…Local pollution in the Arctic from shipping and oil and gas industries, which have expanded in the region due to a thawing of sea ice caused by global warming, could further accelerate that thaw, experts say.
