Figure 6.12. Temperature reconstructions for regions in the SH: two annual temperature series from South American tree ring data (Villalba et al., 2003); annual temperature estimates from borehole inversions for southern Africa and Australia (Huang et al, 2000); summer temperature series from Tasmania and New Zealand tree ring data (Cook et al., 2000, 2002a). The black curves show summer or annual instrumental temperatures for each region. All tree ring and instrumental series were smoothed with a 25-year filter and represent anomalies (°C) from the 1961 to 1990 mean (indicated by the horizontal lines).
