Jeff Id has an interesting post in which he examines the 148 “missing” series. Check it out. I haven’t verified the calculation, but will do so. I submitted a comment at his blog observing that the two “Fisher” series are actually Dahl-Jensen borehole reconstructions from Greenland. These two series were said to have been used in Mann and Jones 2003, but the construction of the Mann and Jones 2003 composite is, at present, remains considerably more mysterious than MBH.
