The WORST Data Set

Berkeley Earth’s US temperature graph shows an impressive hockey stick.

Berkeley Earth

In 1989, NOAA said the US had not warmed over the past century. Berkeley Earth showed nearly 1C warming during that same period.

U.S. Data Since 1895 Fail To Show Warming Trend –

In 1999, NASA showed the same thing – little or no net warming since 1895, with the 1930s as the hottest decade.

The USHCN raw data shows a cyclical pattern with no net warming over the past 80 years.

The graph below overlays The USHCN data and the Berkeley Earth data at the same X-Y scale.  Their Y-axis temperatures are ridiculously low, so I normalized the Y-axis to the left side of the graph.

The USHCN raw temperatures closely match the NASA 1999 US temperature graph. But that didn’t fit the global warming agenda, so NASA altered the data.

However, NASA data tampering pales by comparison to the garbage Berkeley Earth is producing,

    There is forensic medicine.
    Forensic accounting.
    There are serious investigations into engineering blunders.
    Two glaring omissions:
    Forensic economics–to investigate the absurd theories and practices behind central banking.
    And “Forensic Climate”–to investigate the absurd theories and data treatment in climate promotion.

    • -B- says:

      And ever notice the investigations into medicine, accounting, and engineering are seriously compromised when government is involved?

      The FDA supports the favored medical corporations, government accounting would result in prison if done in the private sector, and engineering investigations into the WTC towers, select airliner crashes, and other politically sensitive events were done in such a way as to have a result that supported the official government narrative.

    Climate Science: Is it currently designed to answer questions?

    Richard S. Lindzen: Alfred P. Sloan Professor of Meteorology at the Massachusetts Institute of Technology and lead author of Chapter 7, “Physical Climate Processes and Feedbacks,” of the Intergovernmental Panel on Climate Change’s Third Assessment.

    The above factors are all amplified by the need for government funding. When
    an issue becomes a vital part of a political agenda, as is the case with climate, then the politically desired position becomes a goal rather than a consequence of scientific research. This paper will deal with the origin of the cultural changes and with specific examples of the operation and interaction of these factors. In particular, we will show how political bodies act to control scientific institutions, how scientists adjust both data and even theory to accommodate politically correct positions, and how opposition to these positions is disposed of.

      Climate Science
      as any other kind of marxistic ‘science’
      is designed to give ALL answers sovjet needs.
      Climate Science is the multitool army swiss knife to give them all results they want and need.
      With all the dataadjustments,rewritten history,cheap excuses,hockeysticks and moved goalposts climate science could be turned tomorrow into the coming ice age if they want to.

      Climate Science is so great,it turned the desperately wanted warming
      climate scientists in the 70ies were praying for to save us from the ice age into something apocalyptic.

      Climate Science may not give answers(but 1000s of new questions),
      but is great to create fear and guilt and a global tax.

    • Good link. Little consideration is given to how people tend to believe what social pressure urges them to believe. Altruism is so entrenched as to almost never be questioned, and Soviet and National Socialism leverage this uncritical acceptance to reinforce the popularity of their derivative memes. Climate disaster goes back to 1960 Soviet conditioning. Millerites went through two Disappointments and changed their name rather than their beliefs in failed prophesies. Is some eminence grise bankrolling them? People are eager to believe nonsense, and that demand gives rise to a supply which can amplify into a vote or revenue stream of bought or conditioned minds.

      • Anon says:

        I seem to have gotten a lot out of this lately. It seems to fit AGW to a “T” and the Berkeley Data:

        So how do we recognize the language of “ideology” and distinguish it from a “principled position”? One common clue is that those who hold a principled position welcome arguments; they welcome having their position tested and possibly corrected. A principled position always has room for increased subtlety and greater complexity.

        Holders of an “ideology,” on the other hand, will tend to eschew argument or any examination of the ideology’s underlying presuppositions or premises, often refusing to concede that greater subtlety may be required to apply the principles to real-life situations. Ideology disdains argument; people with principled positions embrace it warmly and engage in it gladly.

        If, rather than trying to glean evidence from observable reality, a person seems more intent on forcing reality into the categories of his or her system, then you’re dealing with an ideologue. If evidence supporting a theory is trumpeted loudly and repeatedly, and evidence that may refute it is ignored repeatedly, then it’s an ideology, not a principled position. If every bit of data, no matter how contrary, is taken as evidence of the truth of the theory, then it’s ideology, not science.

        • GCSquared says:

          I’ve found 2 indicative questions useful:
          i) Can you explain why you think that what you said is true?
          ii) Can you define that term you just used in your own words?
          Clear thinkers reply thoughtfully, but ideologues can rarely answer these questions directly. They’re usually reduced to indignant sputtering and/or misdirection. The advantage here is that I can tell a person by their reactions, without being misled by what I think about what they think. (I am my own worst ideologue!)

    According to the best-sited stations, the diurnal temperature range in the lower 48 states has no century-scale trend.

    The current rating of surface stations (82.5% surveyed) as of 07/30/2012

    CRN Rating:
    CRN1-2, 7.9%
    CRN3-5, 92.1%

    1 Flat and horizontal ground surrounded by a clear surface with
    a slope below 1/3 (<19°). Grass/low vegetation ground cover
    3 degrees.

    2 Same as Class 1 with the following differences. Surrounding
    Vegetation 5°.

    3 (error 1°C) ‐ Same as Class 2, except no artificial heating
    sources within 10 meters.

    4 (error ≥2°C) ‐ Artificial heating sources <10 meters

    5 (error ≥5°C) ‐ Temperature sensor located next to/above an
    artificial heating source, such a building, roof top, parking lot,
    or concrete surface

    Over 92% of BEST stations have a 1-5C warm bias. The BEST science money can buy.

    It’s funny how the leftoid robots are screaming about fictional warming. I’m sitting here this morning looking at mpegs and photos of our sun over the last few weeks, and it’s completely devoid of sunspots. I’m a bit concerned. I think the world is about to become very chilly. The sun’s output has apparently dropped by 0.1% lately, which is bad. I think I remember learning that the sun’s output dropped by just about 0.5% during the last ice age.

    While the morons on the left are just so sure that the we’re all going to burn up, the reality is clearly that it’s getting colder. I remember the climate when I was a kid in the 1960s and 1970s. It was hot as hell in the summer every year. I live in the same area now, 40 years later, and it’s much colder these days. Single digit temps very often in the winter, more snow and less rain in the winter, cooler summer days and chillier summer evenings. I know I’m right about this. However, I’m sure the Stalinist liars who work for the climate collective will somehow tell me that last year was the hottest on record because thermometers in the third world and stuff, and I’m ignorant, and there’s a difference between climate and weather, and I’m a heretic who should be burned at the stake, and…

      Fear not. when the sun cools, the warm oceans will mitigate temperature.
      And when the sun heats up, the cool oceans will mitigate temperature.
      Wash, rinse, repeat.

    • Hivemind says:

      At first, I couldn’t understand how the lack of sunspots could affect the sun’s output. Then I realised that the sunspots are created by turbulence inside the sun. Turbulence is what increases heat transfer from the core of the sun, where the nuclear reactions happen, to the surface, where radiation of heat happens. So without turbulence, the heat transfer is reduced & the suns output diminishes.

      It isn’t because the sun is burning less fuel, but because the heat transfer isn’t happening. It’s a little bit like a bathtub with hot water on the bottom and cold water on top. It isn’t stable long term, but it needs an initial disturbance to create a path by which the hot water can move above the cold.

  5. Johansen says:

    This is all so confusing, I just don’t know who to believe, with the Internet we have so much information it’s just so confusing, and our Great and Glorious Leaders have told us we’re warming, and I’ll trust NASA any day over Tony, and isn’t he a Denier and Birther and Occupier and an oil company stooge, and can’t we just have one really truthful news source that tells us everything so everyone isn’t so confuuuused?

    • neal s says:

      How can you trust NASA when NASA from before does not agree with NASA now? To me this means some combination of lying and/or incompetence. The common history from older NASA charts should match that same history from more recent ones. The fact that they don’t is proof of lying and/or incompetence from NASA. Tony has made his code available for all to use. Just try it for yourself.

      • -B- says:

        I remember back in the mid 1990s when the warmists argued the temperature data was entirely accurate and required no adjustments, error corrections, etc. Today they argue that it needs adjustments and error corrections. Then they redo those over and over again no less than annually. So let us assume these people aren’t simply lying to fit data to their theory, their actions indicate a data set that is simply absolute garbage.

        So either the raw measurements are fine and errors follow the rules for large data sets and drop out as Tony has shown or it is complete garbage or “climate change” is a fraud. There’s no option for “climate change” is real. Simply there isn’t any, we don’t know, and fraud.

          I sincerely hope that those that are busy doing those adjustments are sitting at home right now not getting paid. They probably are.

          It took this truck driver an hour to pass through customs this morning at the Ambassador bridge between Detroit and Windsor. Usually it takes 15 minutes or less at 02:00. When I pulled up to the booth I noticed the officer was an older black guy. He looked a bit frazzled. Once he had asked his questions and handed back my pass port card I told him. “Thanks man for hanging in there”. He looked at me and with a little smile said “Thanks”. He’s there doing an important job and not getting paid and to my way of thinking every American should be recognizing and thanking all of those customs and border patrol or any other “nonessential” government types that are sticking to their guns and doing their jobs.

        Well, as the Arctic ice is no longer melting at the rate it was and is even growing, NASA now says an ice-free Arctic is DECADES OFF and possibly wont happen until the END OF THIS CENTURY:

        Wintertime Arctic Sea Ice Growth Slows Long-term Decline: NASA

        These model simulations showed that in the 1980s, when Arctic sea ice was on average 6.6 feet thick in October, about 3.3 extra feet of ice would form over the winter. That rate of growth has increased and may continue to do so for several more decades in some regions of the Arctic; in the coming decades, we could have an ice pack that would on average be only around 3.3 feet thick in October, but could experience up to 5 feet of ice growth over the winter.

        “This negative feedback mechanism increasing ice growth is unlikely to be sufficient in preventing an ice-free Arctic this century,” Petty and his colleagues concluded.

        That is quite a walk back from Mann’s 2008 and Gore’s 2014 ice-free Arctic forecasts. So you can tell your panicked “warmist” friends, NASA says an ice-free Arctic is decades if not a century away (assuming you buy this latest explanation as being written in stone).

        As NASA can’t adjust the actual ice, their only option was to adjust the theory.

        For “Johansen” believe who you want, but ……
        From Eisenhower’s famous “military industrial complex speech”

        “Today, the solitary inventor, tinkering in his shop, has been overshadowed by task forces of scientists in laboratories and testing fields. In the same fashion, the free university, historically the fountainhead of free ideas and scientific discovery, has experienced a revolution in the conduct of research. Partly because of the huge costs involved, a government contract becomes virtually a substitute for intellectual curiosity. For every old blackboard there are now hundreds of new electronic computers.

        The prospect of domination of the nation’s scholars by Federal employment, project allocations, and the power of money is ever present – and is gravely to be regarded.

        Yet, in holding scientific research and discovery in respect, as we should, we must also be alert to the equal and opposite danger that public policy could itself become the captive of a scientific-technological elite.”

          That cold is going to reach some of us in Hoosier land. Temperatures up to -30 C below normal for us coming down from up your way. Big limb off that same western pine that was hit by lightning two years ago has come down due to the icing and wind. Thankfully the freezing rain has stopped and it’s turned to snow but I would not be surprised of some more limbs come down due to the weight of the snow added to that of the ice.

    In his Friday video Joe Bastardi said that he predicts that from January 15th through March 14th both the US and Europe will record the greatest number of “heating degree days” so far experienced in this century.

Without the cooling drenching of rainfall from these events, the temperature of the interior of the continent will soar driving high pressure systems that push this super heated desert air towards the various coast lines where most of the people live and a brain dead media eagerly awaits to report record breaking high temperatures. Australia is likely to be hit hard by dryer hotter summer conditions as the next ice age approaches. This is a conundrum poorly reported and understood.

      Potholer is as toxically effective.
      In his book “Propaganda”, public relations guru (and Freud’s nephew) Edward Bernays describes how, in the 1920’s, he seduced American women to start smoking cigarettes, largely by making the advertising suggestion that cigarettes represented “freedom”. His campaign took no more than 20 couples in New York to ignite the flame, so to speak.
      We’re all inclined to listen to Potholer’s nice, trustworthy British accent, and we might even feel like we’ve learned something profound after watching his “tipping point” see-saw animation.
      It’s amazing how good propaganda can get people to think they’re asserting their ill-defined “freedom”, or preventing some imaginary “tipping point”, by accepting totally irrelevant beliefs inculcated by competent manipulators. All without realizing precisely why.

      True, Tony does not adjust the data. Why would you adjust continuously active class one and two stations? Why does NOAA adjust perfectly good Iceland readings that are already adjusted by the
      meteorologist on location? Why do NOAA adjustments invariably result in a greater warming trend? Especially inane when the majority of errors result in artificially induced UHI, and should be adjusted down.

    You can’t show this theme too many times. When I personally started looking into climate seriously, my attention quickly focused upon discrepancies between alarmist and skeptic temperature plots, and Mueller’s (of Berkeley Earth) statement that temperature rise correlated with CO2 concentration and nothing else (I was inclined to believe him since his research had been funded by the Koch’s.)
    Your 41 min lecture video, where you explained the adjustment process, and showed how temperatures correlated with CO2 (and of course, time), clarified the discrepancies. It became obvious that warming was a fabrication, and that Climategate wasn’t an anomaly, but the tip of a larger iceberg of deeper corruption.

    Friday afternoon I spent an hour watching the video of the quarterly safety meeting the company I work for has. It’s required. A driver that doesn’t attend or watch the video of the meeting will not receive safety and performance bonuses. Of course this time of year the meeting topics center around winter driving and truck maintenance.

    They also reported on the new camera systems they’re testing. Both have dash cam and driver cam. I feel better about the one facing the driver after seeing how it works. Both cameras record on a loop and only transmit if the driver initiates them or if the truck sensors indicate hard braking, turning, etc. The industry has done several studies and estimates that about 80% of claims against truckers are fraudulent or end up with the trucking company being found liable when they should not have been.

  20. JCalvertN(UK) says:

    The BEST algorithm seems to be very skilful at detecting step-change errors in the surface temperature record – especially *downward* steps (and we don’t like those do we?).
    And it is quite incapable of detecting gradual errors – especially gradually *increasing* errors like UHI.
    Now I’m pretty sure that all these step changes must be preceded by a long-drawn-out gradually built-up error.
    Typically, a weather station is established in a small rural hamlet which grows over several decades into a substantial town with lots of paved roads and car-parks. Then the weather station is then moved out of town to a more rural location (usually the local airfield).
    This causes a saw-tooth-shaped error pattern – a gradual build-up over several decades followed by a sudden cut-off.
    The only correct way to adjust for such a saw-tooth-shaped error (but I question the need for any adjustment at all) would be to impose an upside-down saw-tooth shaped correction. (see below)
    BEST (and all the others) don’t do this. By selectively adjusting for the sudden obvious down-step but not for the preceding gradual UHI rise, they are very effectively cooling the past (a.k.a pollution of history).
