Blogger Finds Y2K Bug in NASA Climate Data

    Years of bad data corrected; 1998 no longer the warmest year on record


    A friend of mine just pointed this out to me. Very... interesting.

    thanks, thats interesting... frankly though, I think that the global warming propaganda, even if it is bs, is for the best. People are slow to react unless there's eminent danger... procrastination is human nature. How else are we going to make the public take environmentalists seriously? =)

    As far as I can see, 2005 has been listed as the warmest year (and continues to be), with 1998 in second place. Also, every year since 1986 has been warmer than the warmest pre-WWII year.


    EDIT: I see that the OP's article talks about US temperatures, not Global temperatures. Globally, the top 5 warmest years all still happened since 1998.

    Still, it's pretty shocking that such important data can go through apparently very poor quality control.

    The OP is refering to this http://data.giss.nasa.gov/gistemp/graphs/Fig.D.txt [Broken]

    That's the part that I find a little unnerving. I wonder what other collected data is lingering out there that has also been skewed. Imagine if there was actual intent behind the data skewing rather than it being an honest algorithm error.

    sounds like a good idea for a science fiction/conspiracy theory book, someone tell Dan Brown...

    It is interesting that the conspiracy theorists reporting on this either fail to mention that this has a negligible effect on the global temperature trends, or they bury it in their rants about "media hype".

    I guess they are talking about the global warming confined to the US. :rolleyes:

    And it's funny, that we don't even have a definition for what exactly we're measuring. http://data.giss.nasa.gov/gistemp/abs_temp.html

    Whoops! NASA off by decades on hottest year

    Are you kidding? It was a mistake which caused a major error.

    Whoops! NASA off by decades on hottest year

    Hank Aaron wasn't the only one to lose his record last week amid swirling controversy. Climate scientists seemed unprepared for (or perhaps just blasé about) the media backlash after a correction to a NASA analysis stripped 1998 of its title as the hottest year on record in the U.S. That dubious honor was rightly returned to 1934, the year the infamous dust bowl devastated the Midwest. Climate data dabbler Steven McIntyre of Toronto, formerly a mining executive with the Northwest Exploration Company, Ltd., alerted agency scientists of the error after spotting it earlier this month while sifting through recent NASA records of temperature anomalies. Apparently a NASA team overestimated the average 1998 temps by 0.06 degree Fahrenheit, making 1934 the new hottest year title holder by a slim 0.04-degree margin. The correction caused a veritable heat wave of excitement among conservative commentators, but NASA researchers brushed it off, noting that average global temperatures are still on an unprecedented upswing. (NASA update; Steven McIntyre's blog)
