Al Gore’s Global Warming Hysteria the Result of a NASA Programming Error

This is big, big news. Al Gore’s global warming cause is based upon NASA graphs that say 1998 was the hottest year of the millennium. It turns out that is completely wrong. 1998 was not the hottest year; that distinction goes to the year 1934. Here’s the nut of the whole thing from Anthony Watts:

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..

Here is one of his first posts where he begins to understand what is happening. “This imparts an upward discontinuity of a deg C in wintertime and 0.8 deg C annually. I checked the monthly data and determined that the discontinuity occurred on January 2000 – and, to that extent, appears to be a Y2K problem. I presume that this is a programming error.”

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 which you can see here:

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. (World rankings of temperature are calculated separately.)

You must read all of Watts’ piece, in which he provides a ton of information from Steve McIntyre who did the analysis. If NASA’s original and wrong data was the basis for the current global warming hysteria, then this new and corrected data should be shouted from the rooftops because it debunks Al Gore’s argument that global warming is man made and that the science has been settled. Many, many others have seized upon this earth shattering information and are offering their analysis:

Rush Limbaugh also discussed this on his radio show yesterday. You can read what he said here.
