OK, this is the easiest piece:
"There is more than one "official" surface temperature record, based on actual land station records. There is the one we have developed in CRU, but there are also the series developed at NCDC and GISS. Although we all use very similar station datasets, we each employ different ways of assessing the quality of the individual series and different ways of developing gridded products. The GISS data and their program are freely available for people to experiment with. The agreement between the three series is very good."
Dr Jones' findings are not based on the actual land station records. It's based on data he modified from the real data. He freely admits he changed the actual land record to generate his "official" surface temperature record. That's cooking the books.
Their has never been an independent review of the real data. As a matter of fact if you check a few other sources, you will find that Dr. Jones claims that much of the real data is lost cannot be verified.
Reading further you see that there are three different datasets all derived from the lost real data. All different and only GISS allows anyone to see their data. If this is science and there is a scientific method of converting actual land station data to "official" surface temperature records, then this process would be open and repeatable.
So Dr Jones is 100% sure that we have global warming, he bases this on data that he won't show us, he admits it was changed from the original data using a method he won't tell us, and he claims he lost the original data.
