The East Asian monsoon plays an integral role in human society, yet its geological history and controlling processes are poorly understood. Using a general circulation model and geological data, we explore the drivers controlling the evolution of the monsoon system over the past 150 million years. In contrast to previous work, we find that the monsoon is controlled primarily by changes in paleogeography, with little influence from atmospheric CO.

- The Late Cretaceous period saw a shift from a very warm climate to cooler temperatures without major ice formation on land.
- Researchers utilized a method called TEX86 to analyze sea surface temperatures (SST) from the North Atlantic region during the Campanian-Maastrichtian interval (around 83-66 million years ago).
- Their findings indicate that North Atlantic SSTs were initially around 35°C but dropped significantly to below 28°C by the Maastrichtian, suggesting a widespread cooling effect likely linked to decreasing atmospheric carbon dioxide levels.
Erba et al. (Reports, 23 July 2010, p. 428) attributed calcareous nannofossil morphology and assemblage changes across Cretaceous Oceanic Anoxic Event 1a to the effects of surface ocean acidification.
