there is a far more pressing need to wade through SST procedures

For sure, HadCRUT3 is approximately 0.75*HadSST2+0.25*CRUTEM3, i.e. weight for SST is 0.75 and for land data 0.25.

That’s why I don’t understand why Brohan adds UHI to uncertainties, instead of correcting by that negligible value. He is being held as a prisoner at metoffice, and he wants to send us a message?

It troubles me that a small subset of humanity appears to be causing large and rapid changes to the historical climate.
