Double shot coffee in hand, I arrived at the AusIMM Future Mining Conference at 7:45 am to register and sign in. After a welcome from my supervisor Serkan Saydam the conference kicked of with a presentation from Nick Holland, CEO of Gold Fields about what the gold industry is likely to look like in the future. Apparently we are in store for a drop in gold production in 5-7 years due to a hiatus in exploration now which will begin to manifest itself, and we will see more automation, with Rio Tinto’s driverless trucks already saving ~500 work hours each per year.
One interesting presentation was titled ‘Integrating measurement, systems and leadership to build safe, productive cultures’ by Malcolm Roberts. The key messages were reducing variation in production to reduce waste and increase productivity (using the Taguchi loss function), and that safety and productivity need not be mutually exclusive in terms of budget. It’s not safety OR productivity, increased safety DRIVES productivity. Roberts ended with a rather provocative statement (which was only semi-related) that the ‘angry summer’ of 2012/2013 in Australia was only anomalous relative to the previous year, and showed the graph from this site (which I’ve never seen before).
Roberts suggested that all senior mining employees in Australia knew that global warming was fake, yet didn’t have the leadership to speak out about it. One of the audience members challenged this by asking whether the fact that the industry didn’t speak out about it was more due to the fact that it accepted the 97% consensus that anthropogenic global warming was real. Roberts replied by saying that the 97% consensus was false, and when you really look at the data only 0.3% of scientific papers on climate change support AGW. This was news to me. I’ve asked Roberts for comment and will write a follow-up piece on this.
Carlos Tapia Cortez, another PhD student of my supervisor gave a talk on ‘Copper price uncertainties – Chaos theory to manage risks in mining projects’. Put simply, Carlos put forward the hypothesis that copper prices can be forecast using chaos theory, fractals, artificial intelligence and econophysics, just as they have been used in neurosciences, meteorology, aviation and market trading. Overall the proof was a little beyond me, and I can’t say I was completely convinced that it works – but it was a proof of concept study. The next step is to actually simulate future copper prices and test how the analysis compares to reality, and to try it for different commodity prices. One might wonder if, were this analysis to work, would it cease to work almost straight away? If it became that easy to predict copper prices and thus buy low and sell high every time (arbitrage), people would stop selling and buying respectively at these times.
Seeing Malcolm Roberts and Brian Cox in Q & A prompted me to finally finish this piece. In short, Malcolm Roberts claimed global warming was a hoax on national Australian television, and physicist Brian Cox debated him (or rather, showed Roberts some evidence which was rejected).
Shortly after writing this piece, I reached out to Roberts for clarification on his talk, and he gave me permission to reproduce our conversation here.
I enjoyed your presentation today at the AusIMM Future Mining Conference. That was certainly a provocative way to end a talk! If you don’t mind I had a few questions in hindsight.
Regarding your plot of temperature vs. time highlighting the ‘angry summer’, where is that sourced from? I haven’t seen that particular graph before.
Regarding the notion that the ‘97% consensus is actually 0.3%’, that seems exceptionally low. Given that I have met a lot of climate scientists and all of them have supported AGW, I’m a little surprised by this. Am I stuck in a bubble? Where are the 99.7%?
Thank you for your email and inquiry.
Here’s a summary of the empirical evidence on climate:
Although not requested, both are pertinent to your questions.
John Cook’s behaviour in fabricating the 97% consensus forms part of my formal complaints. Those complaints and my correspondence with the VC cite a scientifically peer-reviewed paper that demolishes Cook’s fabrication. It’s the source of my figures in Appendix 5, above.
Similar fates have befallen other claims of 97% consensus. These have been comprehensively explained elsewhere.
Note that none of Cook’s 0.3% have provided any empirical evidence of human causation of global warming or climate change.
Note further that anyone claiming a consensus is undermining science since the decider of science is empirical data, not voting.
Journalists with limited understanding of science accessed basic data to disprove the Gillard-Flannery Climate Commission’s claim.
I chose that graph because it illustrates the lack of any process change in Australian summertime temperatures. There are many graphs of annual temperatures confirming no change in temperatures.
There are no graphs and no data showing process change in global climate or any climate factors.
I say this, Michael, not to embarrass you. That the majority of people were misled is not their fault. There has been a barrage of misleading and evocative material flung at the public by a small group of people portrayed as authoritative with that material re-presented by a large group of well-meaning though misinformed people. We humans are easily misled, especially when emotions are deliberately involved.
When you visit Appendix 5, enroute perhaps peruse the documentation of extensive corruption of climate science in appendices 3, 5, 6, 6a, 7, 8, 9, 10, 11, 12, 13, 13a-13g, 14, 15.
Then consider whether or not you’ve ever actually seen specific empirical evidence and logical causal analysis of climate proving that carbon dioxide from human activity causes global warming or global climate change or global climate variability.
There is none. Neither BOM nor CSIRO Chief Executive has ever provided any to MPs as my Freedom of Information requests confirm.
None of the nine most prominent Australian academics fomenting climate alarm has ever provided any in their responses to my requests.
The ultimate arbiter of science is empirical evidence.
I hope this answers your questions fully and meets your needs.
Hi Malcolm, thanks for your detailed response.
I’m not embarrassed – I don’t believe I told you my personal stance on climate science.
I write a blog covering fields related to my research, and wrote several summaries on the Future Mining Conference. I was asked by several readers to expand upon your presentation, especially the content relevant to climate science. Would you be comfortable if I referred to some of the content of your response? If not, I will make no mention of it.
Thank you, Michael.
Please accept my regret for the sloppiness of my wording. I didn’t mean to imply that you specifically should not be embarrassed and I had not meant to imply any assumption regarding your stance.
It was my clumsy attempt to empathise with a possible believer in human causation while simultaneously conveying to a possible sceptic to extend understanding to those who have fallen for climate claims. Please note my use of the word ’their’ in reference to people who may have fallen for climate claims.
Secondly, I try to live life openly and would be delighted for you to use any of my material and any of my response in context. Thank you for the courtesy of asking.
If you cite The Australian’s article, please do so on the basis that I am not using it as scientific proof, and am using it only to show that even two journalists with apparently limited scientific background (if any) were able to easily debunk the government’s ‘experts’ who had implied the 2013 summer was unusually hot when it was not.
In summary, while I was deliberately ambiguous in these emails, after examining the evidence myself (having studied climate change at university in my undergraduate degree – see also my analysis of common myths around anthropogenic global warming) I am of no doubt that global warming is significantly more likely than not to be real, to be caused by humans, and to be a big problem. And quite frankly, even if we were only 0.3% sure that this was the case, I would still advocate for doing something about it. After all, there is a chance it lead to the extinction of humanity
, which would be very bad indeed. How much risk are we willing to accept when it comes to our literal extinction?

Looking forward to reading your commentary on ‘false facts’ with global warming
Nice work Michael.
I agree with your conclusion at the end.
To be honest even if it wasn’t happening we are still using up limited fossil fuels and need to transition to renewables whilst readily accessible fuels are available to provide the energy needed for a transition. It’s just that climate change means we need to do that even earlier.
As someone who wants to live in a post scarcity world the fact that the price of energy from renewables goes down over time is rather important. You don’t get that overall curve with fossil fuels nor nuclear.
