Unlike CO2, which remains in the
atmosphere for a very long span of time, black carbon is something we could tackle on a short timescale,
by mandating things like filters on
diesel engines and the cleaner burning of coal and biomass.
A recent paper
by Dr. Tami Bond and colleagues finds that carbon aerosols — particulates released into that
atmosphere from a variety of human activities including
diesel engines, open cook stoves, poorly filtered coal burning, and open burning, etc. — have played a much larger role in impacting the climate than has been previously recognized (and included in climate models).
