Researchers find Northern Hemisphere glaciation enhances orbital- and millennial-scale Asian winter monsoon variability

In a study published in Nature Communications, researchers have documented that persistent millennial-scale Asian winter monsoon (AWM) intensity fluctuations were superimposed on 41-kyr and ~100-kyr orbital variability during both the warmer (higher CO2) late Pliocene and colder (lower CO2) early Pleistocene, in response to both external astronomical forcing and internal climate dynamics.
