But look: The predictions for the future would be more dire than before
especially as the
aerosol cooling would not be expected to keep up.
As most
aerosols,
especially sulfate
aerosols, are emitted in the NH, the
cooling effect should be largest there.
Dirt particles in the atmosphere,
especially sulphate
aerosols, have created a certain
cooling effect and has prevented a stronger temperature increase at the moment.
Similarly, atmospheric
aerosols, generally human - caused, can increase albedo and
cool the planet —
especially if they also increase cloudiness by providing condensation nuclei for WV.
Karsten: So the take - home message would then be that 1) In the mid-century the NH
cooled because of anthropogenic
aerosols (
especially the most polluted areas) 2) Now anthropogenic
aerosols have a larger content of absorptive elements so directly observing this
cooling in the most polluted areas is very complicated but we can nevertheless be sure that the global effect of these
aerosols is markedly negative.
