McCracken data here is the 10Be data record inverted and normalised to the CETs. Intensity of the GCRs is in the reverse proportion to the Heliospheric magnetic field, with geomagnetic field subtracted. There should not be any significant correlation between two, as is case after 1960 when 10Be satellite measurements became available. North Atlantic Precursor ( possibly the true initiator of the N. Atlantic climate changes ) appears to form a base line for the CETs and the inverted 10Be records except for the 1840-1890 period. 10Be data should closely correlate to the sunspot cycle as is the case after 1960.
