did have some debatable aspects to do with the calculations and the lads quickly picked up my gaffe in saying the pre-1976 / GPCS temperature data did have a downward trend overlooking the fact that M&Q used data from 1951 not the whole data from the beginning of the La Nina period in 1942; even so, despite there being a slight upward trend from 1951 -1975 [the year before the GPCS], the
average temperature for this period is -0.194 C
below the
anomaly base period of 1961 - 1990; the
