Self-Fulfilling Prophesy From Gavin Schmidt

In 1998, Gavin warned us that climate data sets will be “distorted and twisted beyond all usefulness”

Eos, Vol. 79, No. 28, July 14, 1998

Unless we are vigilant, “data sets” will evolve and data that have been so painstakingly collected and saved will be distorted and twisted beyond all usefulness. Our care in using data should be a force analogous to natural selection, keeping data sets fit for the purposes intended. If we do not take care, the gold standards of climatology may in time turn to lead.

All that is labeled data is not gold – Schmidt – 2006 – Eos, Transactions American Geophysical Union – Wiley Online Library

And that is exactly what he did. The animation below shows how Gavin has altered the US temperature record since 1998, and turned the gold standards of climatology into lead

    I got this email response a couple days ago when I wrote GISS about allegations that they are manipulating past temperature data…
    “Thank you for checking with us about those allegations.

    It is true that our estimates for the global mean temperature anomalies occasionally change, since we base them on the best currently available data; those do change with time as records from more stations are digitized and made available, as corrections to earlier incorrect reports are obtained, as metadata are used to account for changes in reports that have nothing to do with climate change but were caused by changes in instrumentations, reporting procedure, location of the measuring instrument etc. Finally, those estimates may change slightly as the time series get longer, which allows us to assess better how to combine records from different stations and how to bridge spatial or temporal data gaps. Sometimes those changes result in increasing trends, sometimes trends are decreased. It seems that the sources you consulted cherry-picked the former instances.

    A major change that decreased the trend happened when we included ocean temperatures in addition to land based sources only, and a slight decrease was caused when we adjusted the data for urban effects. All other changes had only minor effects on the global means.

    Any major changes/adjustments have always been documented on the web and in the scientific literature by the people who made them (mostly NOAA/NCDC) and so did we whenever we adopted those changes, so none of the graphs you refer to is news to us.

    • It is so cool how they added ocean temperatures to the lower 48 US temperature record. Is that the Kansas Sea, or the Tennessee Sea they added?

        It’s all way above my “pay scale” to have a valid opinion, but I told him I expect nothing but the facts and the truth from now on. 🙂 Keep up the good work!

    Not sure if this is the right place to link this but here goes. I think you met Jenny in Las Vegas at the conference but here, is Not Spinning Jenny but Spinning BOM

    Interesting stuff and right up your cycle track

    Now I understand the 1910 bathing suit. It must have been a lot colder in those days.

    Now bathing suit 1998

      Even better, with the “adjusted” warming temperatures, chances are good the “headlights” will be “on” 😉

    Always thought Gav was a budding Alchemist!

    Thank you, Steven aka Tony, for using your keen analytical mind and your communications skills for their intended purpose: To benefit all mankind.

    These same talents in the mainstream scientific community were used selfishly for personal gain and power over others after 1945, turning the scientific method into a tool of false government propaganda and the gold standards of climatology into lead.

    Sixty-nine years (2014 – 1945 = 69 yrs) of deceit are now in open conflict with reality:

    Indeed, intentions are everything.
