Extended Data Fig. 2: Pre-Industrial control model validation.
From: Atmospheric CO2 control of spontaneous millennial-scale ice age climate oscillations
a) Modern global average time-depth profile of ocean potential temperature differenced from observed (∘C) (see67 for observed data). b) Global average ocean potential temperature from the modern simulation. The modern observed value is also shown in purple c) Same as in a) but for salinity (practical salinity units). Global ocean overflow parameterizations66 have been turned off in the modern control simulation and a BL profile63 has been used for the vertical mixing.
