Enhanced hydrological cycle increases ocean heat uptake and moderates transient climate change

The large-scale moistening of the atmosphere in response to increasing greenhouse gases amplifies the existing patterns of precipitation minus evaporation ( P − E ), which, in turn, amplifies the spatial contrast in sea surface salinity. Here, by performing a series of transient CO 2 doubling expe...

Zusammenfassung:	The large-scale moistening of the atmosphere in response to increasing greenhouse gases amplifies the existing patterns of precipitation minus evaporation ( P − E ), which, in turn, amplifies the spatial contrast in sea surface salinity. Here, by performing a series of transient CO 2 doubling experiments, we demonstrate that surface salinification driven by the amplified dry conditions ( P − E
