Serious issues with global temperature data

Who would have thought?

John McLean audited the HadCrut4 global data from 1850 onwards for his PhD thesis, and then continued it on afterwards till it was complete:

“I was aghast to find that nothing was done to remove absurd values… the whole approach to the dataset’s create is careless and amateur, about the standard of a first-year university student.”
– John McLean

His supervisor was Peter Ridd, famously sacked for saying that “the science was not being checked, tested or replicated” and for suggesting we might not be able to trust our institutions.

McLean’s report could scarcely have come at a more embarrassing time for the IPCC. On Monday, it will release its 2018 Summary for Policy Makers claiming that the global warming crisis is more urgent than ever. But what McLean’s audit strongly suggests is that these claims are based on data that simply cannot be trusted.

    Many seemingly sensible people have accepted the AGW scam and now can’t be swayed.

  2. But never let the Age miss an opportunity to point out how bad Australia is regarding our obligations to save the world. In their most recent example of comprehensive journalism (only joking) their intrepid girl reporter stated:

    Deaths from air pollution would be prevented and the Morrison government would meet its pledge to make electricity more reliable and affordable if more Australians drove electric cars, but a lack of political will is holding back the benefits.

    That is the widespread view expressed to a Senate probe into electric vehicles in Australia. Electric car maker Tesla, headed by controversial entrepreneur Elon Musk, is among those who assert that “government leadership” is the main barrier to increasing electric vehicle uptake in Australia, while the government’s own infrastructure adviser warned that Australians “risk being left behind” in the global transition.

    As I wrote elsewhere:

    The solution for these writers and their supporters is always more government intervention into people’s lives and subsidies for the wealthy, no matter what the consequences. And their arguments are always predicated on selective statistics (no surprise) that if analysed fully have more holes than a shark net. Note that in the totality of the European Union, 287,000 electric cars were sold in 2017 and yes, Norway was in first place. But that figure represents 0.15% of total European Union vehicle manufacture in 2017.

    You could easily pull apart every so-called fact stated in the article.

    McLean has been doing great work for yonks; for instance this early piece on the temp record around the GBR which completely contradicts alarmism:

    Deaths from air pollution would be prevented and the Morrison government would meet its pledge to make electricity more reliable and affordable if more Australians drove electric cars, but a lack of political will is holding back the benefits.

    This is fraudulent reporting on many levels.

    I doubt air pollution causes any deaths in Australia at all.
    In any case CO2 is not pollution.
    There is no correlation between electric cars and reliable and affordable electricity. The car can be recharged by coal or intermittents*.

    Many, if not most, terrestrial temperature records come from airports.
    That is because airports legally must collect weather data for pilots.
    So governments get the data for no cost.
    Paying for a weather station in woop woop is expensive.
    Unfortunately airports have lots and lots of asphalt and hot jet exhausts.
    So the data is crap.
    You know what they say about getting stuff for nothing.

    And the bureau is closing down met stations in whoop whoop places like Quilpie, interpolated model data grids will do!

    That said, observations rule, so I am not quite on board with what Maclean is saying either.

    Before we make drastic lifestyle changes and spend $40 trillion based on this report, we’re going to need full transparency …

    “The IPCC was established in 1988 by the World Meteorological Organization (WMO) and the UN Environment Programme (UNEP) to assess, in a comprehensive, objective, open, and transparent manner, the scientific, technical, and socio-economic information relevant to understanding human-induced climate change, its potential impacts, and adaptation and mitigation options.”

    2018: “IPCC sessions are closed from the public, to allow governments and scientists to speak freely.”

    Many of those people don’t understand science. If you put forward the counter argument, enen on simple terms, they look at you blankly and say “I don’t understand that.”

    John should check GISS for an even bigger laugh.

    For example, Darwin raw mean temp data (prior to around 2011).
    https://data.giss.nasa.gov/cgi-bin/gistemp/show_station.cgi?id=501941200004&dt=1&ds=1

    Darwin adjusted mean temp data (cleaned and homogenised after 2011).
    https://data.giss.nasa.gov/cgi-bin/gistemp/stdata_show.cgi?id=501941200000&ds=5&dt=1

    And the BoM is just as bad with its ACORN adjusted data and its smoothing processes.

  11. Many of those people don’t understand science.

    They don’t even understand human nature; clearly not considering that there could be ulterior motives afoot.

  12. .

    Does anyone want to adjust, clean and homogenise their tax returns?

  13. “”That is the widespread view expressed to a Senate probe into electric vehicles in Australia. Electric car maker Tesla, headed by controversial entrepreneur Elon Musk, is among those who assert that “government leadership” is the main barrier to increasing electric vehicle uptake in Australia, ..””

    It is clear to blind Freddy that the Senate and indeed the Cabinet should listen carefully to and follow the advice of billionaires who have made their fortunes sucking on taxpayer subsidy teats. You know it makes cents.

    .. Darwin Airport..

    What’s even funnier is that those numbers for the airport are made up prior to approx 1942.

    Here’s the BOM NT airport data, and Post Office Data prior to 1942, which is presumably what their older numbers are based on.

    Despite the growth of Darwin (UHI), temperatures went down from 1880 to 1940 by about 2.5°C !

  15. iggie

    Yes, Duncan.
    And when you look at BerkeleyEarth the adjustments to Darwin are even greater. They change a -0.5 to a +0.6.
