Figure 2.24: Records of
climate variability during the Holocene and the last climatic transition, including
the 8.2 ky BP event (adapted from Johnsen et al., 1992; Hughen et al., 1996; Thompson
et al., 1998; von Grafenstein et al., 1999; Jouzel et al., 2001). The shaded areas
show the 8.2 ky BP event, the Younger Dryas event and the Antarctic Cold Reversal.
The grey scale used in the Tropical North Atlantic record is a measure of sea
surface temperature, deduced from the colour of plankton rich layers within an
ocean sediment core.
