In november I sent a manuscript (Tree Ring Growth Homogeneity Responds to Sun Activity) to Holocene, and have now new results which should also be considered. 1.) We have now the general homogeneity pattern for western Europe (temperate, humid climate) with a significant anticorrelation to sunspots r= 0.67; t-value=12!; correlation to Finland/ Norway: very low. 2.) We also have the homogeneity pattern of Italy (Alps, 1700 m NN) and Spain (1700 m NN), tree ring data supplied by Fritz Schweingruber, which strongly anticorrelates to the west European pattern (r=0.7; t=15), but correlates highly to the sunspot curve (r=0.71). In view of this data, I would like to emphasize more the distinction between a) humid, temperate b) boreal and mountain area climates, and to reduce the emphasis on solar activity. This is also the opinion of Fritz Schweingruber. With best regards, Yours, Burghart Schmidt.
