a–h, Differences in simulated variables during nHSs (a, c, e and g) and HSs after the onset of SO convection (b, d, f and h) relative to IS conditions for annual mean near-surface air temperature (a and b), net carbon flux to the atmosphere (c and d), zonally averaged radiocarbon ventilation age (e and f) and zonally integrated dissolved inorganic carbon content (g and h). The filled circles in a and b represent temperature changes estimated from proxy records16,23,58. The green lines in a–d show the maximum sea ice extent during the IS, while the grey lines represent the maximum sea ice extent during nHS (a and c) and HS (b and d). All ocean fields in e–h are shown separately for the Atlantic Ocean (Atl) and the Indo-Pacific (Indo-Pac) Oceans, with the SO sectors being included.
