Abstract:
Based on the international research on division of Upper Pleistocene-Holocene millennial-scale climate strata in the latest 20 years, the regional chronostratigraphy comparison table for the past 270ka compiled in 2012 is analyzed, and division of Upper Pleistocene-Holocene millennial-scale climate strata and research progress in China are reviewed. To the reasons of climate instability, a number of scholar views that accounted for the driving mechanism are cited, and the conclusion that millennial-scale climate changes were climate oscillations caused by the forcing factors of solar activity outside the Earth coupling with the Earth inner climate system is drawn.
