Kawamura et al. (2007) presented high-resolution chronologies of the last four
glacial terminations. Their results are compared with those of Rothlisberger et al.
(2008) in Figures 10.10 to 10.13 . There is very good agreement between these two
investigations. The variation in peak solar intensity at 65 N and 65 S is also
