The spatiotemporal distributions of global paleo-Köppen climate belts during the Mesozoic-Cenozoic

Climate paleogeography refers to adding climatic information to traditional paleogeographic maps by using paleoclimate classifications. Here we present a series of global paleo-Köppen climate maps from 250 Ma to 0 Ma (per 10 million years) with a high resolution based on the quantitative paleoclimate data simulated by Li et al. (2022). Based on these maps, we evaluate the areal and latitudinal evolutions of paleo-Köppen climate belts during the Mesozoic-Cenozoic. Based on an updated classification that divides “Hothouse”, “Greenhouse”, and “Icehouse” states by global average temperature, we evaluate the areal, latitudinal, and altitudinal characteristics of the paleo-Köppen climate belts for different climate states.
