A number of reconstructions of millennial-scale climate variability have been carried out in order to understand patterns of natural climate variability, on decade to century timescales, and the role of anthropogenic forcing. These reconstructions have mainly used tree-ring data and other data sets of annual to decadal resolution. Lake and ocean sediments(More)
An objective method for homogenization of early (pre $1850) instrumental near surface air temperature records is developed. The method is grounded on the same variational principle as used in the objective analysis of meteorological ®elds; i.e. the method consists of a statistically optimal spatial-coherence-based adjustment of nearby station temperature(More)
