CC BY 4.0 License. 27 Abstract: 28 29 Climate exerted constraints on the growth and decline of past human societies but our knowledge 30 of temporal and spatial climatic patterns is often too restricted to address causal connections. At 31 a global scale, the inter-hemispheric thermal balance provides an emergent framework for 32 understanding regional Holocene climate variability. As the thermal balance adjusted to gradual 33 changes in the seasonality of insolation, the Inter-Tropical Convergence Zone migrated 34 southward accompanied by a weakening of the Indian summer monsoon.
