Theory 13/Refinement
Aerosol Cooling Is Smaller
The claim
Aerosol cooling is smaller than mid-range estimates because absorption by black carbon offsets scattering by sulphate.
01Mechanism
Absorbing aerosol warms while scattering aerosol cools.
02Prediction
Net forcing should be less negative than scattering-only estimates.
03Refutation
Net forcing matching scattering would remove absorption.
