The CMIP6 multi-model ensemble of ESMs show varying levels of consensus on projected changes in surface soil moisture with global warming . As in CMIP5 , uncertainties are substantial, often associated with uncertainties in projected regional precipitation changes , and in most regions, both increases and decreases are projected across the ensemble. In the far north of North America and Asia, projected changes in soil moisture at 4℃ global warming range from a 20-30% decrease to an increase of 30-40%. In northern mid-latitudes, projections range from a 10- 20% decrease to an increase of 20-30%, except for eastern North
