Apparently the algorithm NASA was using the crunch raw climate data suffered from a Y2K bug that skewed the numbers. The operators of climateaudit.org were forced to reverse engineer the algorithm after NASA's James Hansen (best known for his claims of White House censorship) refused to share it. NASA has since admitted to the error and republished the numbers. The changes result in a 1-2% downward correction in overall warming trends. 1934 also surpasses 1998 as the warmest year on record and 5 of the top 10 warmest years in the 20th century occur before WWII."
