Dear Keith,

my best wishes for 2001. I hope You are well.

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.
