Figure 17. Simulated difference between mid-Holocene and present-day vegetation cover (black hatched area; from Claussen & Gayler, 1997, and green hatched area, from Renssen et al., 2003). The blue shaded area indicates the area in the simulation of Liu et al. (2006) with simulated abrupt changes in vegetation. The stars indicate the position of records from Lake Yoa (eastern location) and from ODP site 658 C (western location). (Redrawn from Brovkin & Claussen, 2008).
