More Smoking Guns That GHCN Is Garbage

Illinois GHCN airports show warming, while the non-airport stations show cooling.

When I see stuff like this, it sends up a huge red warning flag, which reads “complete garbage.” Both sets of temperatures were taken covering the same state over the same time period. The divergence in polarity tells us that something is fatally contaminating  the data. The graph below indicates that the S/N ratio is probably an unbelievably poor < 0.25.

    Were those with or without TOBS GIGO? 😉

    Obviously cornfields have a cooling effect, which requires endless annual adjustments

    Are you using the corrected USHCN data or the raw data?

    You need to use the adjusted data from USHCN version 2. NCDC revealed:

    “The adjusted USHCN CONUS temperatures are well aligned with recent measurements from NOAA’s U.S. Climate Reference Network (designed with the highest climate monitoring standards for siting and instrument exposure), thus providing independent evidence that the USHCN provides an accurate measure of the U.S. temperature.”

    With respect to the unadjusted data, NCDC stated:

    “The most important bias in the U.S. temperature record occurred with the systematic change in observing times from the afternoon, when it is warm, to morning, when it is cooler. This shift has resulted in a well documented increasing cool bias over the last several decades and is addressed by applying a correction to the data.”

    It appears that you may be using the uncorrected USHCN data, which due to well-documented biases, does not accurately represent the U.S. temperature record.

    Richard Muller says UHI is fiction. So Richard has disrupted “settled science,” and leftists agree, “settled science” can be overturned.

    I claim “greenhouse effect” is fiction. So I guess leftists are open to throwing out old beliefs when they can’t account for the facts.

    My open minded colleagues, the leftists.

    • Don Sutherland says:

      He absolutely says no such thing. He says that the impact of UHI in the adjusted data is virtually non-existent. That is entirely different from saying that UHI is not real. Instead, he’s saying that the corrections that are applied account for virtually all of UHI.

      • Brian G Valentine says:

        Richard Muller, Don Sutherland, and Brian Valentine all agree:

        Can’t see it = doesn’t exist.

      • Don Sutherland says:

        Neither Dr. Muller nor I believe UHI doesn’t exist. The correction largely addresses the problem, removing its impact from the data.

      “My open minded colleagues, the leftists.”
      Why do people like you drag politics into this? It’s like saying “Well the scientists say the Earth is 4.5 billion years old BUT THEY ARE ALL LEFTISTS AND COMMUNISTS SO IM GOING TO IGNORE THEM”

      Science is science. Data is data.

      I think the only reason you bring politics into this is if anything contradicts your way of thinking it has to be aligned with things that you hate – e.g. the ‘vast leftwing conspiracy’ (of which I’m a card-carrying member).

      You better watch out because late at night we steal your underpants for profit.

      • Brian G Valentine says:

        The word “data” is the plural of the word, “datum.”

        “Profit” is a bourgeois concept. You’re a traitor to your own cause.

    Please send your donations now, to help these poor UHI deniers learn how to read…

    • Brian G Valentine says:

      It’s not their problem, it’s yours. Quit relying on “20th century math.”

      • gator69 says:

        I’m sorry, I forgot to add my ‘feelings’ to the raw data.

      • Brian G Valentine says:

        The right feelings, yes.

        Not “feelings of anger about Communist “skeptics” who pander to the left for more Government grants.”

        Feelings of sympathy, one gets from forlorn looking polar bears, for example.

  6. WOT says:

    “The right feelings, yes. ”

    Pity science doesn’t operate on ‘feelings’, padawan.

  7. gator69 says:

    Hansen ‘feels’ it was cooler than the data shows for the 1930’s, and he lets this get in the way of truly objective science. There is no excuse for altering historic data. If you ‘feel’ it is incorrect, then you have your ‘opinion’, but not data.

    2nd chart looks upside down… Shouldn’t the difference be positive on the right?
