Brief communication: Arctic sea ice thickness internal variability and its changes under historical and anthropogenic forcing

We use model simulations from the CESM1-CAM5-BGC-LE dataset to characterise the Arctic sea ice thickness internal variability both spatially and temporally. These properties, and their stationarity, are investigated in three different contexts: (1) constant pre-industrial, (2) historical and (3) pro...
