Meaning, it should only be valued for its 11,000 ybp — 1500ybp (ish) reconstruction (with its error bars) THEN
something like Mann et al (2008) takes over with some overlap at the beginning through to 1950 THEN the instrumental record, with overlap at 1850... Stitching together the reconstruction from the beginning of the Hollocene through to the present using
different methods and error bars with each... and each standing or
falling with respect to their primary era of focus.
