Abstract

The hypothesis that the tropical oceans lead the global warming at the Termination I and II by ~2,000 to ~3,000 years (Visser et al. 2003) whereas melting of the northern continental ice masses is lacking behind challenges the Milankovitch theory of climate change and emphasizes the role of the tropics for global climate change. Although the simultaneous multi-proxy approach of planktonic foraminiferal Mg/Ca, δ18O and δ44/40Ca from tropical sediment core SO-164-03-4 (16° 32.37′ N; 72° 12.31′ W; 2,744 m) from the Caribbean tend to confirm the observation by Visser et al. (2003) we interpret the shift between Mg/Ca and δ18O in core SO-164-03-4 to be due to local changes in sea-surface salinity (SSS) variations triggered by glacial/interglacial related shifts of the Inter-tropical Convergence Zone (ITCZ).
