The relative weighting of these controlling factors needs to be known, in order to prognosticate the variability of precipitation in Central Asia, which is of enormous importance for the development of the regional national economies. Novel proxy approaches are applied to these archives combined with climate modeling that allow to reconstruct the natural variability of the East Asian summer monsoon during the Holocene and last 5 interglacials MIS 13, 11, 9, 7, 5. We are investigating changes in the vegetation and the hydrological cycle in the catchment area of the Pearl River during these climate periods. A model-based comparison of the natural development during the previous interglacials with the already anthropogenic affected Holocene development aims at assessing the relative weighting of natural and anthropogenic forcings. Thus, INVERS will broaden the knowledge base on climate change in Central Asia and will improve scenarios outlining the future dynamic of the monsoon system.
