by Canadian statistician Steve McIntyre discovered an incongruity in temperature data published and used by NASA. The error was found in the algorithm used to calculate the warmest years, and was actually a Y2K bug. When the blogger notified the scientists of GISS of the error, NASA re-released the data (quietly and without coverage as of yet in the major media) and it shows that the warmest year on record in the US is now 1934, rather than 1998. According to the corrected data, 5 out of 10 of the warmest years in the United States occur prior to World War II. While the effect of this on global temperature data is minimal—1-2%, it certainly begs the question: how much of what we hear about Global Warming is hype, and how much is substance?

Way out of proportion by scottb :: NR7 :: Show

Does it really beg that question?
The NASA data had very tiny errors. The largest were around 0.15 degrees. The corrected data is virtually indistinguishable from the uncorrected data. The anti-global-warming crowd really has blown it way out of proportion, though.
Here’s another article.
