  • Descrição: The Pleistocene is characterised by a variable climate and precipitation regimes that were periodically subjected to drastic changes (e.g. Shackleton 1982; Dansgaard et al. 1993; Petit et al. 1999;Waelbroeck et al. 2002; Jouzel et al. 2007; Scholz et al. 2007; Thackeray 2007). However, little isknownof the local environmental settings of Middle Stone Age (MSA) sites in southern Africa, even though climatic changes play an important role in discussions surrounding developments in human behaviour. To complicate matters, recent research shows that local climatic circumstances do not mirror global climatic trends recorded in ice and deep sea cores (Chase & Meadows 2007; Chase 2010). Local (sea surface) temperature and precipitation regimes are influenced by the relative strength of the cold Benguela and warmAgulhas currents and the location of the subtropical convergence zone. However, the exact effects of these on local temperatures and precipitation are unclear (compare for example Stuut et al. 2004; Jacobs et al. 2008b; Bar-Matthews et al. 2010; Chase 2010).
