Description:We explore current variability and future projections of winter Arctic sea ice thickness and growth using data from climate models and satellite observations. Winter ice thickness in the CommunityEarth System Model ’s Large Ensemble compares well against thickness estimates from the Pan-Arctic Ice Ocean Modeling and Assimilation System and CryoSat-2, despite some signi ficant regional differences —for example, a high thickness bias in Community Earth System Model ’s Large Ensemble in the western Arctic. Differences across the available CryoSat-2 thickness products hinder more robust validation efforts. We assess the importance of the negative conductive feedback of sea ice growth (thinner ice grows faster) by regressing October atmosphere/ice/ocean conditions against winter ice growth. Our regressionsdemonstrate the importance of a strong negative conductive feedback process in our current climate, which
