Extending The History Of NASA Global Temperature Fraud

This is the current NASA land surface temperature graph, which shows steady warming from 1880 to 1980, and then faster warming since 1980.

Their graph looks nothing like the 1974 graph from the National Center for Atmospheric Research, which showed a worldwide cooling trend from 1940 to 1970, and no warming from 1870 to 1970.

The National Academy of Sciences reported the same thing.


National Geographic reported the same thing, and pointed out that the early 1880’s were cold because of the eruption of Mt. Krakatoa.

The current NASA graph looks nothing like the prior graphs, and has completely erased the post-1940 cooling.

Thirty years ago, Tom Karl (longtime head of NOAA’s National Climatic Data Center) said most global warming occurred before 1919, and that Earth cooled from 1921 to 1979.

NASA now shows about 0.4C warming from 1921 to 1979.

Over the last two decades, NASA has steadily altered their data, to more than double warming prior to the year 2000.


I have documented this fraud many times over the past decade, but here is some new information about warm temperatures NASA is hiding prior to the eruption of Krakatoa.

In 2001, NASA included temperature data going back to 1867. It showed no warming from 1867 to  1979, and showed 1878 as being the warmest year prior to 1980

The first four months of the year showed little or no warming, with March 1878 being the most anomalously warm month on record.

After the year 2001, NASA apparently made the decision to hide the hot years prior to 1880, and start their graphs during the cold period around the time Krakatoa erupted.


1878 was an incredibly warm year, and is now being hidden by NASA. There was no winter in Minnesota that year.

January/February, 1878 may have also been the hottest on record in Australia.

14 Sep 1878 – Great Heat at St. Louis. – Trove

23 Feb 1878 – BRISBANE. – Trove


11 Jan 1878 – THE EXCESSIVE HEAT. – Trove

There was something exceptional going on with the weather that year, around the world. Instead of trying to understand it, NASA chose to hide it

After massively altering the data over and over again, hiding the record heat of 1878, starting their graphs around the time of a volcanic eruption, and pretending that the 1974 NCAR, National Academy of Sciences and National Geographic graphs don’t exist – NASA claims that everyone precisely agrees.

The boldness and arrogance of these fraudsters seems to know no bounds, because they know that the press and politicians are afraid to confront them  – even though they do it right out in the open.

    Another great post.

    These posts are professionally devastating for NASA and their previous and current ‘climate scientists’, yet they say not a word. If you’re wrong they’d be all over this blog, suing you into oblivion for professional defamation. Their silence is so telling.

    I’m tired of waiting for the US Administration to take action against these scam artists. It’s no exaggeration to say there should be colossal jail sentences handed down to these people.

    They’re misrepresenting US government data (paid for by US taxpayers) in the process driving insane $multi-million policies and enriching their own careers and bank balances. It’s a clear case of malfeasance in public office.

    Maybe Trump can’t go after them as he doesn’t control both US Houses, but whatever the reason it’s well-past time these racketeers were held to account.

      Very well put!

      Whistleblower needed like Landis did to Armstrong and netted a cool mil.

      No one will ever go to jail. They rationalize away their “adjustments” and the cooling of the past – warming of the present will continue even if we slip into a mini ice age over the next few decades. Tony will be called names, smeared and threatened. Anyone that does not agree with the “consensus” will be pilloried by the media and called a Nazi. Its all just a power game at this point and they don’t really need to do “science” – since all they really need are scary stories for the rubes.

      The media is dying anyway. Eventually the powers that be are going to need to use a Chinese style social credit system to police wrong think since the propaganda is no longer as effective as it once was. Then anyone that does not accept the “correct” interpretation of the data will be unable to get a job, get loan, buy groceries, travel, etc.

      We are at the precipice of a system that would have made INGSOC green with envy at its potential for absolute control.

    • Treborp says:

      This “research” is ridiculous. Comparing graphs with different value intervals (.5 degree intervals vs .1 intervals vs .2 intervals; 10 year vs 20 year intervals), possibly different x axis (degrees change vs temperature anomalies which do not list the base point), and annual mean temperature vs 5-year mean temperature plotting.
      No NASA graph that I have seen eliminates a 1940-1970 cooling trend as seen from 1940-1970. But as a trend from 1880-2020 (or from 1867-2020) (or 1850-2020) or (1650-2020) 1940-1970 was a minimal cooling trend. To look back on that period from current times it seems ridiculous to use this period as an analysis for what has happened in the past 50 years.

    Wow… just wow. What’s depressing is how not only the measured, scientific record is changed but also how the contemporary historical record of the time is ignored and our “objective” media ignores all of it. It’s not surprising… but it is depressing.

    Thanks again for all that you do.

    • xenomoly says:

      The media is owned by 6 corporations that also sell weapons and all manner of consumer garbage. They don’t care at all about truth. Their goal is management of the cattle (us). The farmers don’t care that some of the cows realize that this is not a dairy farm and THEY are on the menu.

    Tony – Thank you for this analysis. In an earlier comment I remarked that the austral summer of 1877-1878 might be the hottest in the last two centuries. Temperature data before 1877 is sparse, so it is interesting to read the Minneapolis Tribune clipping you posted, which begins:

    “Observations on the weather have been kept at Fort Snelling since 1819. There is nothing in the memory of the living or the records of the dead that give us such a winter and spring as we have passed in the last four or five months.”

    Fort Snelling is located just a few miles from Minneapolis and St. Paul, which means that this area has had continuous weather observations since 1819 – exactly 200 years ago. One cannot extrapolate the Minnesota temperature record to the rest of the world, but it merits notice that, at least here, the winter of 1877-1878 is the warmest of the past two centuries.

  4. Martin Hughes says:

    Great research. You may find this interesting. It seems like an honest attempt to look at how adjustments are made and also tries to devise a better way of estimating surface temperature. Interestingly he finds that while warming is not evident in the maximum temperatures the minimum temperatures do show a warming trend. Warming, if it is occurring is happening at night. I thought at first that this could be due to the changing land use disrupting nighttime stratification as Christy points out, but there seemed to be something similar over the oceans too.

    Very interested in this research

    Hi Tony,

    I have visited your webpage many times and have found the information within it very interesting and informative.

    Based on your good work and that of others, I am of the belief that NASA is manipulating temperature data. When I have tried to find the reason(s) for it I came across articles about motives such as those found on page 40 of http://www.conscious.com.au/__documents/Thriving%20with%20nature%20and%20humanity_single.pdf written by Senator Malcolm Roberts of Australia. He refers to NASA (and other government-funded organisations on page 88 of http://www.conscious.com.au/docs/new/14_Appendix.pdf. I was wondering whether you could provide any information which indicates why NASA is manipulating temperature data.

    Thank you

    Facts are that we now know more about climate, medicine, space and other sciences than we did about 40 or 50 years ago.
    Don’t trust the science of this time? Go back to live like people did back in the 1900s then dude.

  8. Robert Hisey says:

    NASA has been hiding their Satellite infrared data since the work was done in 1991. I have finally found it as Appendices E and F of an obscure Technical memorandum. Never published. this seems to have been the area of the Goddard Space center. If you wish to see the actual data, which proves that added CO2 will not cause more warming, go to NASA and look up NASA Technical Memorandum 103957, Appendix E, F. by Lord, 1992. There it is with unlimited distribution allowed. The Goddard was run by an avowed warmist.
    Pass this info on.
