Post Script to GISS at Mackay


Breaking News:  An initial brief look at the data suggests data manipulation at Cairns and Mount Isa and something very strange at Gladstone!  I will be checking this in the next few days- watch for another post.

I have made a number of small changes to my original post below.  These mainly reflect a revision of data for Barcaldine and Willis Island, and some small text changes.  I no longer claim GHCN data is  “out”, just much of it is inexplicably missing. 

These changes have not made any change to the overall conclusions. 

The adjustments, presumably for Urban Heat Island effect, are UPWARDS for both Te Kowai and Mackay, when any correction should try to reduce the effect. 

In contrast, Mackay’s neighbouring regional cities of Rockhampton (330 km south) and Townsville (400km north) both have been adjusted correctly (although I have yet to verify the surrounding rural stations). 



Those who mistake me for a ratbag denialist who sees no good at all in the opposite camp, please note:  it seems GISS can adjust temperatures for UHI correctly when they want to. 

The question remains: why did they make such unwarranted adjustments to Mackay, and why did they make such a huge reversal to Te Kowai (Mackay Sugar Mill Station)?

Thank you to readers who have given me much encouragement.  I am very chuffed by your support.

    I was transferred to Cairns by Ansett in early 1984 to take over as manager of the Cargo operation. At that time our shed was just next to the tower where the temperatures were taken (and I presume still are).

    At that time we handled 4 domestic flights a day. one cargo aircraft and one international flight a week (to a mine in Irianjaya).

    After the new air port opened the number of aircraft movements exploded in just a few years to the point where my staff were handling 12 domestic flights a day and 60 international flights a week. And an entirely new International Passenger Terminal had to be added.

    The relevance of this being that the engineering base(s) were directly in front of the tower and all the jet engines were tested, blasting their exhaust directly back over the area where the temperature equipment was stationed. That, combined with the extraordinary tarmac extensions adding vast areas of extra concrete to the air port could hardly have failed to affect any readings (in my opinion, of course).

    Certainly – I have just been looking at the airport on Google Earth and there have been a lot of changes since I retired 9 years ago and I can’t quite work out whether or not the weather station is still located in the same position. If it is there are new buildings and extensions around the general area where it was when I was there.

    Ken and others
    Thought you might be interested in this site
    it’s a blog about

    2.Applying straight-forward analysis methods.
    3.Presenting results, code, and data sources.

    I’m sure you’ve heard about the latest CSIRO and BOM relesse “It is very likely that human activities have caused most of the global warming observed since 1950
    There is greater than 90% certainty that increases in greenhouse gas emissions have caused most of the global
    warming since the mid-20th century. International research shows that it is extremely unlikely that the observed
    warming could be explained by natural causes alone. Evidence of human influence has been detected in ocean
    warming, sea-level rise, continental-average temperatures, temperature extremes and wind patterns. CSIRO
    research has shown that higher greenhouse gas levels are likely to have caused about half of the winter rainfall
    reduction in south-west Western Australia.”

    I’d like to make a FOI request to both the CSIRO and BOM
    there are a number of you who are more expert than I am; what should I ask for so that their data can be checked by enthusiastic amateurs

      Hi Val
      Will be doing a post on this ASAP but a bit pressed- work, family, cyclone coming….

      We need details on exactly which station data this is based on, details of Torok’s adjustments in 1996 and any since, and all raw and adjusted data for these sites.

      Thanks and good luck!

    Hi Ken; good luck with the cyclone; here’s someone who has done a fair bit of home work on the ARCS network
    and a reader’s comment at Andrew Bolt’s blog on

    Installment 3 of the CSIRO+BoM “robust, peer-reviewed” climate report – this time looking at the Reference Climate Station (RCS) Network with the help of Google Earth. The RCS is the BoM’s subset of monitoring stations used for “high quality, long-term climate monitoring” (their words, not mine).
    According to the BoM website, the stations are selected for their “location in an area away from large urban centres”. In all probability, this is the set of stations that was used for the CSIRO+BoM work of fiction.
    The RCS comprises 103 stations, covering all states and territories, plus the Antarctic Territory and several offshore islands.
    An analysis of these 103 stations shows that:
    – 49 (47.6%) are airports (including 6 RAAF/RAN air bases)
    – 16 (15.5%) are Post Offices or locations within a population centre
    – 14 (13.66%) are locations just outside a town
    – 9 (8.7%) are located at lighthouses (big lumps of cement)
    – 15 (14.6%) are locations that could be classified as “rural”
    So, it appears that of the locations selected for Australia’s “high quality, long-term climate monitoring”, nearly half are at airports, and over a quarter are in or adjacent to population centres. Even most of the Antarctic stations are located amongst the settlements.
    (end of comment)
    Does any of that help?

    Ken hope the cyclone hasn’t done too much damage; look forward to seeing you back on your blog

    Gday Val,
    Power back on 4 a.m. this morning (Tuesday) ; phone back on about 10 a.m. We’re lucky compared with most, many still have no power, phones, some have no water and several roads still closed. We were towards the southern edge of the destructive winds. No building damage but many trees and branches down. Huge tree over power line beside us. The worst was in the eye about 100-120 km north of here. No work for me today- no phones and power at school and only a few kids.

    and who could say it better
    From the hills over Hobart’s Sandy Bay, the lights from at least one house will be blazing even more brightly than usual during Earth Hour on Saturday night.

    That would be the family home of emeritus professor Garth Paltridge, former chief research scientist of the CSIRO’s division of atmospheric research, visiting ANU research fellow, and fellow of the Australian Academy of Science.

    Paltridge, an Australian Enlightenment man to his bootstraps, will most likely be upstairs in his study, working on some new learned paper on climate change. He will also be plotting new ways to help arrest what he sees as the continuing sad decline of institutional science in Australia, under the pressures of the global warming ‘doomsday cult’ whose followers will be turning out their lights for the hour.

    This week I phoned Paltridge to hear what he had to say about the CSIRO’s new six-page publication, ‘The State of the Climate’, produced with the Bureau of Meteorology. This, of course, is the leaflet that has been seized upon eagerly by the warming alarmists at the ABC and elsewhere for some desperately-needed reassurance that all is not lost in the wake of the Climategate and IPCC scandals. To Paltridge, it’s just another sad indication of the decline in scientific objectivity. ‘This is a slipshod, slippery little document,’ he tells me. ‘It looks as if it’s been hastily thrown together by some committee. They don’t even tell you from what data they’ve drawn their conclusions.’

    He points to the assertion that Australian average temperatures ‘are projected’ to rise by 0.6 to 1.5 degrees by 2030. ‘Projected from what?’ he asks. ‘From their own past observations? Or from climate models? They don’t say.’

    Hi! Quick question that’s entirely off topic. Do you know how to make your site mobile friendly? My weblog looks weird when browsing from my apple iphone. I’m trying to find a template or plugin that might be able to fix this issue. If you have any suggestions, please share. Appreciate it!

  11. Charmain Says:

    I leave a leave a response when I especially enjoy a post on a site or I have something to add to the conversation. It is a result of the passion displayed in the article I read. And on this article Post Script to GISS at Mackay | kenskingdom. I was excited enough to create a leave a responsea response 🙂 I do have some questions for you if it’s okay. Could it be only me or does it look like some of the responses come across like they are left by brain dead visitors? 😛 And, if you are writing on additional online sites, I’d like to follow anything new you have to post. Would you list the complete urls of your social pages like your Facebook page, twitter feed, or linkedin profile?

    I’m gone to say to my little brother, that he should also pay a quick visit this webpage on regular basis to
    obtain updated from most recent information.
