Abstract. The future surface mass balance (SMB) will influence the ice dynamics and contribution of Antarctic sheet (AIS) to sea level rise. Most recent SMB projections were based on fifth phase Coupled Model Intercomparison Project (CMIP5). However, new CMIP6 results have revealed a +1.3 ?C higher mean near-surface temperature than in CMIP5 at end 21st century, enabling estimations warmer clim...

This manuscript assesses climate change impacts to the North Sea and Baltic Sea using the regional bio-physical model ECOSMO forced by output from three CMIP3/A1B and three CMIP5/RCP4.5 global Earth System Models (ESMs). The main findings of the manuscript are similar to those of previous studies. However, the paper is poorly organized and not all the necessary information is presented. It is n...
