Email 4975, convenient urbanization: Phil Jones ignores it when it hurts "the cause", uses it when it helps the cause

Bottom line is that he got it right most of the time, but not always. He has Oxford and Cambridge data in at times and Oxford has a slight urban warming bias for some decades between 1881 and 1940. No-one knows how Manley did it or what series he used. Just documenting it all for posterity would be good !
