In another fictional story of 'global warming,' it was claimed that 1998 was the warmest year on record in the US (part of ye olde 'runaway warming').

However, more investigation by climate skeptics appears to have handily debunked that claim as well, causing NASA to retract its claim and reinstate 1934 as the warmest year on record in the US.



Steve McIntyre, of Toronto operates www.climateaudit.org and began to investigate the data and the methods used to arrive at the results that were graphed by NASA’s Goddard Institute for Space Studies (GISS).

What he discovered was truly amazing. Since NASA does not fully publish the computer source code and formulae used to calculate the trends in the graph, nor the correction used to arrive at the “corrected” data. He had to reverse engineer the process by comparing the raw data and the processed data.

He further refines his argument showing the distribution of the error, and the problems with the USHCN temperature data. He also sends an email to NASA GISS advising of the problem.

He finally publishes it here, stating that NASA made a correction not only on their own web page, attributing the discovery to McIntyre, but NASA also issued a corrected set of temperature anomaly data...

According to the new data published by NASA, 1998 is no longer the hottest year ever. 1934 is.

Four of the top 10 years of US CONUS high temperature deviations are now from the 1930s: 1934, 1931, 1938 and 1939, while only 3 of the top 10 are from the last 10 years (1998, 2006, 1999). Several years (2000, 2002, 2003, 2004) fell well down the leaderboard, behind even 1900.

It was never supposed to be a trick question. Which year is the hottest on record? Depending where one looks, there are three different answers: 2006, 1998 or 1934. Until last week, the answer was supposed to be 2006, but it might have been 1998. Now, citing corrections of faulty data, NASA says it was actually 1934. The National Climactic Data Center disagrees; it still says 1998.

The differences are a matter of tenths of a degree Celsius, which might seem to diminish the significance of the corrections. Except that unusually warm years in the 1920s, 1930s and 1950s are themselves only a few tenths of a degree Celsius away from the purportedly dangerous hot temperatures of the present. Only one thing is certain: The political debate over global warming has rushed far ahead of the science.

When researchers checked, they found that the agency had merged two data sets that had been incorrectly assumed to match.

When the data were corrected, it resulted in a decrease of 0.27 degrees Fahrenheit in yearly temperatures since 2000 and a smaller decrease in earlier years.

That meant that 1998, which had been 0.02 degrees warmer than 1934, was now 0.04 degrees cooler.

Schmidt said that researchers had always known that the difference between 1934 and 1998 was so small, it was virtually impossible to rank them.
