Reduction of internal climate variability in surface temperature due to sea‐ice loss since the mid‐21st century
ABSTRACT Understanding the internal climate variability ( ICV ) is a principal challenge in projecting future climate change. In this study, we define the ICV in projection of surface temperature as the ensemble spread of surface temperature using a 30‐member ensemble simulated with the Community Ea...
