Awesome. This is why scientific work needs to be peer-reviewed, and all of the source material made available for others to examine.
NASA has now silently released corrected figures, and the changes are truly astounding. The warmest year on record is now 1934. 1998 (long trumpeted by the media as record-breaking) moves to second place. 1921 takes third. In fact, 5 of the 10 warmest years on record now all occur before World War II. Anthony Watts has put the new data in chart form, along with a more detailed summary of the events.
This reminds me of my blogref to How not to measure temperature which I highly recommend.
