“…During the last decades, much research has occurred worldwide on the impacts of historical climate change, such as on agricultural production, human population and migration, disease and human health, human settlements, human activities, social unrest, and rise and fall of ancient civilizations (Kenneth, 1998;Weiss and Bradley, 2001;Haug et al, 2003;Zhang et al, 2005Zhang et al, , 2006Zhang et al, , 2007Lee et al, 2008;Fan, 2010;Lee and Zhang, 2010;Zhang et al, 2011;Du and Shi, 2012;Amorosi et al, 2013;Chang et al, 2014;Su et al, 2014;Welc and Marks, 2014;Chull et al, 2014). Some of the typical results include the collapses of the Akkadian civilization in western Asia and the Mayan civilization, induced by persistent drought (deMenocal, 2001;Haug et al, 2003), and the strong coincidence between climate change and major events in the history of Europe over the past 2500 years (Büntgen et al, 2011).…”
