22 (Miller et al. 2014); Figures 2 and 4 of that paper likewise
omit LU forcing.

So, as well as the previously flagged acceptance that the F2 × CO2 value of 4.1 W / m2 was wrong in the original paper, the authors now accept that
LU forcing had indeed been
omitted from the Historical forcing values.
But it seemed pretty obvious to me that
LU forcing might well have been
omitted, and both straightforward regression analysis and comparison of the spatial patterns pointed to its omission being a near certainty.
Certainly, it seems to me that
LU foricng could have been
omitted from the calculation of total forcing if there was some bug in the code used to perform the calculations (or possibly if there were an error in the settings used).
He has looked into it and can see no evidence of
LU forcing having been
omitted for the Historical simulations themselves.
In it, I showed regression results that provided evidence strongly suggesting that
LU forcing had indeed been
omitted from the reported Historical forcing data values.
Another reason that the outlier
LU run 1 should be
omitted when estimating the effect of
LU forcing is that the greatly enhanced cooling it displays is linked to an abrupt cooling of over 5 C in the Labrador Sea.
