Short summary
This research explores the connection between the mid-Holocene northward shift of the Intertropical Convergence Zone (ITCZ) and Hadley cell changes and effects on terrestrial hydroclimate. Our findings show that the ITCZ shift coincides with a contraction and weakening of the northern Hadley cell and an expansion and intensification of the southern cell, leading to reduced (increased) terrestrial aridity and dryland contraction (expansion) in the Northern (Southern) Hemisphere.
