Soot-covered ice speeds melt

Reuters reports on the study showing how soot-covered Arctic ice accelerates its melt.

Scientists at the United Nations climate talks this week in Poland say that global warming efforts should be redirected to soot, ozone, and methane reduction from Europe, Russia, and the USA:

"'Reductions in these pollutants would have a greater impact' in the next two decades than curbing emissions of the main greenhouse gas -- carbon dioxide," they say.

Dark colors absorb more sunlight, so the black pollution particles from industry and vehicle exhaust that now cover the Arctic ice are speeding its melt.
