Small, new, remotely-operated, unmanned aircraft are being flown in the Arctic to measure black soot. The soot is produced by burning diesel fuel, agricultural fires, forest fires, and wood-burning stoves. It is transported by winds to the Arctic, where it darkens the surface of snow and ice, enhancing melting and solar warming. See http://saga.pmel.noaa.gov/ andhttp://www.pmel.noaa.gov/edd/manta.html

Black soot is not a pollutant, it’s 100% natural. How do you even know black soot comes from human emissions? There’s black soot on Venus, explain that!
Maurizio just wants to take away people’s freedom to enjoy nice things like log fires and BBQs, even though most soot comes from China and India.
No to a BBQ tax!
It all just shows jason and dana are in the fight only to hate somebody, and for them it’ sto hell with the climate, the glaciers and the children. Keep it going guys.
Mercury is dark. I suppose that’s because the Mercurians are having too many BBQs!
This government report (written on paper stolen from the private sector) says we don’t even know enough about black soot to know if expensive, economy wrecking, strategies to control soot would even be effective.
