Magnitude and pattern of Arctic warming governed by the seasonality of radiative forcing
Observed and projected climate warming is strongest in the Arctic regions, peaking in autumn/winter. Attempts to explain this feature have focused primarily on identifying the associated climate feedbacks, particularly the ice-Albedo and lapse-rate feedbacks. Here we use a state-of-The-Art global cl...

Observed and projected climate warming is strongest in the Arctic regions, peaking in autumn/winter.
