Still So good Attraction Plave
From the AGU Weekly Highlights, something I’ve pointed out more than a few times. See this photo of a moulin in upper Greenland, where carbon soot has collected at the bottom:
The authors find that BC (black carbon) emitted within the Arctic has an almost five times larger Arctic surface temperature response (per unit of emitted mass) compared to emissions at midlatitudes.
The Arctic is especially sensitive to black carbon emissions from within the region
Black carbon, also known as soot, emitted from combustion of fuels and biomass burning, absorbs solar radiation in the atmosphere and is one of the major causes of global warming, after carbon dioxide emissions. When black carbon is deposited on snow and ice, the soot-covered snow or ice absorbs more sunlight, leading to surface warming. Due to the large amount…
