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).
