It's actually easy to refute much of her analysis. For example;
1- she says "the last editor who published me had his journal shutdown: GeoResJ was discontinued in 2018", implying that the reason that GeoResJ was shut down because it published Marahosy's paper. In fact, GeoResJ had a fairly low Impact Factor and a quick Google shows that it was allegedly not getting enough submissions - and that its own publisher found that the editor had acted unethically.
There is no evidence at all that I can find that the journal was shut down because it published papers against the consensus - it was shut down because of a bad editor and poor performance.
2- She also repeatedly claims that the BoM is trying to hide the fact that Australia's record temperature was allegedly hit in Bourke in 1909. However, it takes very little checking to see why there is a very good reason that the BoM has ignored that temperature. Put it this way, pubs are not the place to get scientific data!
Marohasy has made a huge deal out of the Bourke data, but she either ignored the local newspapers of the time or didn't bother to check them.
3- There seems to be a huge amount of cherry picking going on. For example, she works with Ken Stewart, not a scientist, who has done a paper looking at temperature data for 104 sites. However, he ignored the data for 19 of the sites, without giving any reason for it! Of course you can find trends if you just throw away 20% of the data!
Interestingly even Marohasy admits several times that the climate is warming.
You seem to be critiquing some pretty banal aspects of the claim. Who cares why a journal shut down.....
Exactly what are you claiming regarding the Bourke temperature reading? If you think it was from a pub wall you are being misled. It was recorded at an official site, in an official Stevenson Screen and was entered into the sites official log where it remained for many years. Recently the BoM removed it from the record claiming no other sites around it had similar readings and so it must have been in error. Until someone looked in the archives and found the next nearest site had a reading almost as high....
You claim data has been ignored and suggest manipulation. There may be good reasons for why he did that. Maybe the data wasn't suitable for a host of reasons. Worth looking into but to properly rebut it you need to assess that data, why it was not used and see if it makes any difference to the outcome if it can be included. Blindly claiming cherry picking because of random reasons is not scientific or valid.
No one is disputing the surface temps have increased over the last 40 years. What is being debated is the extent of that warming and if it is any different to what has been seen in recent times. The Boms data shows significant departure from the satellite data. people are trying to work out why and Marahosy is focusing on the problems with temperature probes being calibrated properly with thermometers and as far as I can see, she has good points.
I will listen to any argument contradicting the conclusions they have come up with but yours are pretty weak bordering on rubbish.
You're not actually listening very hard, and your last line proves it.
1- Marahosy is the one who is making a deal about why the journal was shut down, not. The point you are ignoring is that she is drawing an implication that is utterly unjustified on the available data - in other words she's talking BS.
2- The point about the Bourke data is that Marahosy has made a big deal about it, without apparently even bothering to look at the contemporary newspaper for background. So did you. The underlying issue is that she has made a big issue without doing what could be called due diligence, aka proper investigation using easily obtained sources.
The funny thing is that Marahosy herself is a fan of using local papers as evidence of high temperatures -
jennifermarohasy.com/2014/09/newspapers-as-the-guardians-of-hot-history/I notice that you didn't use the clue I posted to do some research. That goes against the claim that many make, which is that those who believe in the consensus don't do their own research. In this case I did so some research, and it turns out that all the max. temps in Bourke at the time according to the daily reports in the local paper were from the "Federal refrigerator" - NOT from the post office's official thermometer, as you and Marahosy claim, but from a pub's fridge.
Marahosy can't write pieces saying how great local papers are as a source, and then ignore the fact that the local paper at the time and date she specifically makes a big fuss about specifically says that the relevant temps were taken from a fridge, NOT from the post office's thermometer with its Stephenson screen etc.
So Marahosy is relying not on a proper "official" source, but an outback pub's mechanisms - and then making a huge fuss about it. Having done some work in pubs in the outback, there's no way I'd trust all of their technology.
Oh, and notice that (a) there's incomplete records for the day in question and (b) it represents a deviation from normal statistical collection, both of which cast even more doubt on its quality and validity.
3- Sorry, but are you kidding about the fact that I'm "blindly claiming cherry picking" with reference to Stewart's paper? It's utterly unscientific (and not just that, but totally against logic in every area I'm aware of) to just ignore some data in the dataset that the author has selected, without giving damn good reasons in the study.
It's like rolling a six-sided dice 60 times, removing 20% of the results, and then saying that the fact that your results don't include any sixes is "proof" that the dice had no sixes.
No first-year student science student would remove 20% of the dataset they have selected from analysis without giving a reason and then expect to get a pass mark.
If the tax department or a kitesurfing contest scorer ignored 20% of your scores or tax records without giving any reason and then hit you with a bigger tax bill or a worse result based on their new calculations, would you just accept it? No reasonable person would, because no reasonable person accepts that a study can remove 20% of the relevant dataset without giving any reason for doing so, and then claim to come to any reasonable conclusion.
