Clustering climate reconstructions

Clustering climate reconstructions

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 5 clustering, at least in part, but not in an easily ...

Are multiproxy climate reconstructions robust?

[1] 64 climate reconstructions, based on regression of temperature fields on multi-proxies and mutually distinguished by at least one of six standard criteria, cover an entire spread of millennial histories. No single criterion is accountable for the spread, which appears to depend on a complicated interplay of the criteria. The uncertainty is traced back to the fact that regression is applied ...
