| Zusammenfassung |
| A systematic coherence analysis is presented for the set of the most
prominent millennial reconstructions of northern hemispheric
temperature. The large number of mutual coherences underwent a
clustering analysis that revealed five significant, mutually
incoherent ("inconsistent") clusters. The use of multiple proxies
seems to be causing the clustering, at least in part, but not in an
easily definable, physical way. Alternatively, a multidimensional
scaling is performed on the same set of coherences. This results in a
graphic, two-dimensional rendering of the reconstructions whose
geometry (location and distance) is given by the coherences. Both
approaches offer complementary ways in dealing with the
inconsistencies. |
