5 Orbital inclination may still be considered as an additional element of an
astronomical theory of paleoclimates in an enlarged form, provided that
evidence can be found for a true linking mechanism.
6 The spectral characteristics of ice sheet-bedrock models such as the PCM
are similar to the 8 18 0 records: there is no significant splitting of the 100-ka
peaks, their widths are comparable to the data and there is no excessive
power in the 400-ka band.
Acknowledgements
We would like to thank Richard A. Muller for providing us with the orbital
inclination data. A. P. would also like to thank Michael Schulz, who introduced
him to the SPECTRUM program. He is very grateful to Andreas Manschke for
helping him to process the data and preparing the figures presented here, and
to Bjorn Grieger and Reiner Schlotte for carefully reading early versions of this
manuscript. Finally, he would like to thank Klaus Herterich, who stimulated
his interest in the astronomical theory of paleoclimates.
The thorough reviews by Christian Schafer-Neth and Michael Schulz improved this manuscript very much, and we thank them for their effort.
This chapter is Contribution No. 122 of the Sonderforschungsbereich 261 at
the University of Bremen.
