CRU (Climate Research Unit) southern hemisphere temperature stations have remained uncorrected for 25 years – fixed in March 2012 CRUTem4June 25th, 2012 by Warwick Hughes

I know this will surprise people but it seems to be the case – see the email from Dr Phil Jones to Ed Thurstan in Ed’s paper – The Darwin Fiddle. 1MB pdf
I always knew that Jones stated in his 1991 update that “Northern Hemisphere data have been corrected for inhomogeneities, while Southern Hemisphere data are presented in uncorrected form.”
However I always assumed that referred to the station data distributed by CDIAC – in those days on diskettes – and that deep in CRU processing – their stated Southern Hemisphere corrections would have been applied by PDJ’s beloved FORTRAN.
It seems I was wrong to assume that.
Comparing CRUT3 with CRUT4 for various Australian gridcells – taken together with PDJ’s reply to Ed shows that he never got around to applying the hundreds of Southern Hemisphere corrections for 25 years. Simply stunning.
Never forget – that IPCC science is settled science.
