Though it was only figured out a little while ago. Since we've had discussions on this topic in the past, I thought some people might be interested.
Here\'s the link I found that seemed to best summarize the results. Key paragraph:
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.
There are links in the original.
