Extended Data Fig. 7: Sensitivity to base state.
a–d, Time series of the global-mean SAT (a), PRE (b), SHI (c) and ACT (d) anomalies relative to the pre-industrial control. Orange shows the yearly standard ensemble and blue shows the 5-year means of the meltwater ensemble. The meltwater ensemble in these experiments is hosed with 0.1 Sv for 50 years in two separate periods, 1980–2030 and 2050–2100, initialized from the standard ensemble. Solid lines show ensemble means and the dark shading shows the 90% uncertainty in the mean. The solid black lines show the difference between the meltwater and standard ensembles.
