On a similar time horizon, soot boosts warming more than 1000 times as much as the same mass of CO2 does.
By 1900, increased emissions of soot could have triggered the loss of more than 15 m of ice from a glacier's surface; by 1930, the loss could have totaled 30 m or more — magnitudes and timing that can easily account for the Alpine glacial retreat, the scientists contend.

The process also creates tiny bits of soot, called black carbon, and traces of harmful substances, known as brown carbon, which together cause more global warming per unit weight than other human - associated carbon sources.

That was part of the logic for why so many folks have been keen to make a big push on soot and other SLCPs [short - lived climate pollutants]-- the piece that Charlie Kennel, Ram Ramanathan and I had in Foreign Affairs a couple years ago lays out the POLITICAL logic for action in that area as well as the new science showing that SLCPs are more important than previously thought.
