"We examined the transient response to CO2 forcing in a set of 30 climate models from Coupled Model Intercomparison Project Phase 6 (CMIP6) and found that the intermodel spread in OHU efficiency largely depends on the base-state ocean stratification, especially in the Southern Ocean. This dependence is primarily traced to ocean salinity rather than ocean temperature."

Together with my brilliant co-authors I’ve published a paper in Journal of Climate (https://doi.org/10.1175/JCLI-D-22-0468.1) last month. It’s about the historical #oceanheatuptake in two pairs of #CMIP6 models analysed from global and regional perspectives. Ocean heat uptake is a powerful metric to track the ongoing global heating (from the 20th onwards). Intriguingly we find substantial differences across the four #Earthsystem/ #climate models, with one reason being human-made #aerosol #emissions.
