Abstract:
Sedimentological evidence indicates metre‐scale, cyclic changes in global sea‐level during Mesozoic greenhouse climates; the cyclicity is thought to be due to Milankovitch forcing. The absence of continental ice‐caps requires other mechanisms than glacier build‐up to explain these variations. We propose that thermal expansion of the entire oceanic water column may partly explain the observed sea‐level variations on Milankovitch timescales. Using existing climate model results, we show that an increase in deep water temperature of ∼ 2°C and a corresponding sea‐level rise of 1.7 m by thermal expansion can be induced by Milankovitch forcing via increased formation of warm deep waters in low latitudes.
