Causal Links Between Arctic Sea Ice and Its Potential Drivers Based on the Rate of Information Transfer
Arctic sea ice has substantially changed over the past four decades, with a large decrease in sea-ice area and volume. The exact causes of these changes are not entirely known. In our study, we make use of the Swedish Meteorological and Hydrological Institute Large Ensemble. This ensemble consists o...
