摘要

Insolation change is a primary driver for climate variation at orbital scales [1,2].During the Holocene (ca.11.7 ka BP to present),orbitally induced seasonal variations in insolation varied markedly,with a long-term decrease in boreal summer (hereafter summer)and increase in boreal winter (hereafter winter) [2].This offers an opportunity to investigate the climate system's response to insolation forcing.However,previous studies that focused on Holo-cene temperature reconstructions and simulations [3-5] have raised the question of how temperature responds to insolation changes.
