Who Runs The GHCN

January 18, 2015

By Paul Homewood 




The Global Historical Climatology Network (GHCN) is a database of temperature, precipitation and pressure records.

The aggregate data are collected from many continuously reporting fixed stations at the Earth’s surface and represent the input of approximately 6000 temperature stations, 7500 precipitation stations and 2000 pressure stations.

Temperature data from GHCN is used by the three major global temperature datasets, NCDC, GISS and HADCRUT, but who actually runs the network?


It is actually managed by the National Climatic Data Center, NCDC, which is in turn a division of NOAA. NOAA, of course, is part of the United States Department of Commerce.


As an added complication, the USHCN, the United States Historical Climatology Network, is run jointly by NCDC and CDIAC, the Carbon Dioxide Information and Analysis Center. CDIAC is run by the Department of Energy. 


When we talk about the various temperature adjustments that have taken place in the last few years, usually to cool the past, most will have arisen from the GHCN database. Yet GHCN is not the product of some independent and objective scientific body. Instead, it is run by Federal Govt agencies, doing the bidding of their political masters.

Is there any reason why we should trust their data?

      Fortunately, government bureaucrats are not bright enough to figure out why they can’t successfully lie about the temperature outside, . . .

      after lying successfully about nuclear and solar physics for the past seventy years.

      As I recall, an old farmer explained many years ago that everyone has a thermometer – an abstract concept far beyond the reasoning ability of those who invented the Standard Solar Model, Standard Nuclear Model and Standard Climate Models.

    In science, trust nobody but yourself.
    Put your own temp.- and CO2 logger in your garden and draw your own conclusions…

    If the raw data is freely available, then is there any other organisation likely to be ‘better’ as its custodian?

    Thanks, Paul.
    Actually, yes. We can trust the government agencies to do as they are told.

    Thanks for this post! Theoretically, the answer is yeas, but realistic speaking, I vote for no, since they can alter the data according to their political and economical interests…..

    during my initial investigations, I came across a problem, seemingly caused by the UK…

    Although I am also guilty of emotional blind faith (like the Greenies on the opposite team) in what you espouse Paul…my gut feeling is thank you for pursuing this subject in a believable fashion, that screams common sense.

    Why does the U.S. have to have so many different agencies from so many different departments involved in climate work?

    If the Sun is of paramount importance to all Earth’s inhabitants, and . . .

    . . . if leaders of Russian, American, Asian, African and European nations are working behind-the-scenes to use science as a propaganda tool to control the public, they will ask leaders of their own National Academy of Sciences NOT to address publicly nine pages of precise experimental data that FALSIFY:

    1. The Standard Solar Model
    2. The Standard Nuclear Model
    3. The Standard Climate Model

    models they uniformly endorsed for the last seventy years (2015 – 1945 = 70 yr):

    To date this self-identification voting has been unanimously in favor of a tyrannical one-world government that is totally out of contact with reality.

    Yes, because they know they will ultimately be held accountable by the voters.

    Oh, wait …
