The researchers [3] quantified China's current contribution to
global «radiative forcing» (the imbalance, of human origin, of our planet's radiation budget), by differentiating between the contributions of long - life greenhouse gases, the
ozone and its
precursors, as well as aerosols.
There are enough health - damaging pollutants in the air today such that, if they (tropospheric
ozone, its principal
precursor methane, black soot, and some other trace gases that contribute to the
global warming) were reduced by feasible amounts, the planet's energy balance could be restored, or nearly so.
