The Eurasian ice sheet reinforces the East Asian summer monsoon during the interglacial 500 000 years ago
Deep-sea and ice-core records show that interglacial periods were overall less "warm" before about 420 000 years ago than after, with relatively higher ice volume and lower greenhouse gases concentration. This is particularly the case for the interglacial Marine Isotope Stage 13 which occu...
