Government Can’t Prove What Their Climate Change Policies Actually Do!

,

An independent audit office found that the Government’s Climate Change Department can’t prove how much by, or even if, their policies are affecting the climate.

In my opinion, it’s all a scam designed to transfer money out of the pockets of Australians to wealthy billionaires, while doing nothing with a measurable impact on the environment.

It’s time to abandon the net-zero pipe dream, which has no accountability and zero ability to demonstrate its effect on anything. Thankfully we still have a handful of independent agencies like the Australian National Audit Office (ANAO) who are prepared to provide an objective analysis of the government spin.

Transcript

Senator ROBERTS: Thank you for appearing here today. I want to ask about the performance audit report you did on governance of climate change commitments for the Department of Climate Change, Energy, the Environment and Water. You concluded in paragraph 12:  

DCCEEW reports annually on progress towards targets, however are unable to demonstrate the extent to which specific Australian Government policies and programs have contributed or are expected to contribute towards overall emissions reduction.  

I asked the department about your conclusion in estimates in February and again yesterday. I’m not sure if you saw that. Did you see it?  

Ms Mellor: No.  

Senator ROBERTS: They were very forceful in saying that they didn’t agree with your conclusion, and they maintain they do measure the specifics. Can you please elaborate on exactly what you found in terms of the specific policies and programs measurement?  

Ms Mellor: Yes. I think we’ve got the relevant audit leader here to do that for you. Ms Horton: As you’ve correctly characterised, within the overall conclusion, we concluded that DCCEEW, or the department, do measure—broadly and overall—Australia’s greenhouse gas emissions, but we weren’t able to determine the specific contribution that individual Australian government programs made towards that. So it was reported overall, but that further breakdown below.  

Senator ROBERTS: I’m not trying to put words into your mouth. I’m just trying to confirm my own understanding and clarify. They have a number that represents what they estimate to be Australia’s overall greenhouse gas production, but they cannot tell anyone what specific contributions from various sectors or various— 

Ms Horton: They do do a breakdown of various sectors, and that’s in ‘International’ under broad reporting that we provide, and that’s provided there. There have been a number of new measures and additional measures that have been announced under the government. We could see some of those had the specific measures broken down underneath but not all of them.  

Senator ROBERTS: Are there any specific measures or are they projections based upon calculations?  

Ms Horton: They’re projections.  

Senator ROBERTS: That’s my understanding around the world.  

Ms Horton: They have projections where they’re looking forward to what we are aiming towards achieving, and they also report on what we have. So they do both.  

Senator ROBERTS: But again, they’re are not direct measurements because it’s very hard to directly measure carbon dioxide coming out of any—  

Ms Horton: There is that broad process we have in our international reporting arrangements.  

Senator ROBERTS: Who seeks audits? I’ve been through this before, but I can’t remember. Who asks you to do an audit?  

Ms Mellor: Nobody. People can, but the Auditor-General can’t be directed to do an audit.  

Senator ROBERTS: No, no.  

Ms Mellor: We develop a forward work program. We’re required to consult with the parliament. That’s managed through the Joint Committee of Public Accounts and Audit. The Auditor-General’s required to take into account that committee’s view of priorities. My understanding is that that committee writes to other committees and gets views about what’s on the mind of those committees as priorities for audit. Individual members of parliament sometimes write and seek an audit.  

Senator ROBERTS: We’ve done that, and we’re very happy with the way we were treated.  

Ms Mellor: The program is really at the discretion of the Auditor-General. In deciding to undertake an audit, we do look at the coverage across the sector. We look at the sorts of activities that are being undertaken, whether it’s service delivery or asset management, procurement, grants administration et cetera. And then we have to look at our capacity to do it. Do we have enough people with enough skill in the particular area? Do we need to supplement the skill from elsewhere? So it is all at the discretion of the Auditor-General, and we do seek to get coverage across the sector of a wide variety of policy and program areas.  

Senator ROBERTS: You’re continuing your predecessor’s fine habit of being very clear in your answers, so thank you.  

Ms Mellor: Thank you.  

Senator ROBERTS: Is size or potential impact of an error in a department one of the factors for consideration that you would use? In other words, if there’s a huge cost that may be incurred as a result of a mistake in that department, would that be a consideration?  

Ms Mellor: We do take into account risk in different areas, in activities of the public sector. Risk can manifest itself in the size of expenditure, but we also do small things because they’re important and they also provide information to the parliament as well as an opportunity for the public sector to learn from our work.  

Senator ROBERTS: So risk is a consideration?  

Ms Mellor: Yes.  

Senator ROBERTS: You’re minimising risk—or exposure—to taxpayers.  

Ms Mellor: Yes.  

Senator ROBERTS: What’s your response to the department rejecting your conclusion that they can’t demonstrate the specific effect of these policies?  

Ms Jago: We actually included in the report at the end of appendix 1 our response to the department’s response to us, where we outlined why we came to a different conclusion than what the department outlined in their response.  

Senator ROBERTS: What was the number of that appendix?  

Ms Mellor: It’s in appendix 1. Ms Jago: It’s at the very end of appendix 1. There isn’t actually a paragraph number. It’s headed ‘ANAO comment on Department of Climate Change, Energy, the Environment and Water response’.  

Senator ROBERTS: This is important. I’m going to come back to something in a minute. This is discussing understanding or measuring—no, it’s understanding; it’s not measuring, because it can’t be measured—overall emissions reduction. I’m going to come back to another point later that is separate from your report. In the meantime, it’s important to actually know how policies are or aren’t affecting measurable outcomes. Is it right to assume that that’s why you focused on this issue in your report? If not, what was the reason?  

Ms Mellor: It’s typical for us to look at a program. In this case it was a set of activities that are done by the department of climate change et cetera. Then we generally look at the governance, the activity and then the monitoring of the activity. So reporting on the success of a set of activities or an activity is typically what we do, in looking at whether or not the expenditure—the activity—is meeting the outcomes required. It’s not unusual for us to have a criterion that says, ‘Is this being monitored and reported effectively?’  

Senator ROBERTS: But you’ll go beyond that and look at the overall governance of the monitoring and everything.  

Ms Mellor: Correct.  

Senator ROBERTS: If the actual specific effect of policies isn’t being measured, then surely it’s very difficult to measure success or failure, and that’s what your report found—that the department can’t demonstrate those specific effects.  

Ms Mellor: Our report found, as I think Ms Horton has said, that we couldn’t see that line of sight across each of the measures that it was monitoring and about what the measurement showed.  

Senator ROBERTS: Now I’d like to come back to what I foreshadowed a minute ago. There are two measurements that should be in place, I believe. One is the measurement of the amount of carbon dioxide produced from human activity. That’s one thing. But then surely we should be measuring the effect of that carbon dioxide from human activity on a climate variable such as temperature, snowfall, ocean temperature or whatever. Do you see what I’m getting at?  

Ms Mellor: I can, but it wouldn’t be for me to comment on a government policy on those things, no matter who the government is. It’s our job to audit whether or not people are doing, within that policy, what they said they would do. It wouldn’t be for me to strain to what’s appropriate policy or what’s appropriate measurement. It’s whether or not what’s in the policy is being delivered and being measured.  

Senator ROBERTS: Let me just check my understanding there again, Ms Mellor. If the policy said that the specific effect of carbon dioxide from human activity is this quantity and we need to therefore cut the production of carbon dioxide by this quantity, then you would measure or assess both. But, if they don’t have one of them in there, then you’ll only measure what’s in the policy.  

Ms Mellor: It’s very hard to speculate. In a government policy, we would look at how it’s being implemented; whether the implementation is being monitored; what the monitoring shows; and, if there was an outcome overarching that, how that measurement contributes to that outcome.  

Senator ROBERTS: I don’t want to engage in a conversation, because that’s not correct nor appropriate for Senate estimates. It strikes me, though, that to be able to have a policy on emissions reduction you need to have the specific effect of those emissions on some climate variable: temperature, rainfall, snowfall, drought, storms or whatever. Then you measure against that. Without that specific effect quantified, it would be impossible to actually assess different alternatives to implementation, different strategies, and would be impossible to assess or track progress towards achievement of the goals. Am I on the right track?  

Ms Mellor: The ANAO can only audit what’s in front of it. If we go in to audit something of that broad nature, we have to look at what’s in place, how it’s being managed, how it’s being reported and whether that meets the outcome—and not whether the outcome is right.  

Senator ROBERTS: Okay. In your work for various departments, has anyone specified the effect of carbon dioxide from human activity on climate or any part of climate?  

Ms Mellor: It’s not something we’ve audited, no.  

Senator ROBERTS: Sorry?  

Ms Mellor: Not specifically.  

Senator ROBERTS: I didn’t think so, because no-one has been able to tell me that amount.  

Ms Mellor: Not specifically that we’ve audited.  

Senator ROBERTS: Sorry?  

Ms Mellor: We haven’t specifically audited in that space. 

Senator ROBERTS: Okay.

Science is for debating, not blindly following

,

There is a fundamental problem with climate change alarmism. In the two recessions of the last two decades where carbon emissions were hugely reduced, there was no difference to the CO2 in the air and temperature of the world.

Transcript

As an engineer, I respect and consult scientists, because lives have depended on it, and still do. As an engineer educated in atmospheric gases and as a business manager, I was responsible for hundreds of people’s lives, based on my knowledge of atmospheric gases. I listened to scientists, I cross-examined scientists and I debate the science. I have never found anyone with logical scientific points based on empirical scientific evidence that shows we have anything to worry about at all.

The basics are these: when you burn a hydrocarbon fuel, you burn molecules containing carbon and hydrogen with oxygen and they form CO2, carbon dioxide, and H2O, water vapour; that’s it. Carbon dioxide is essential for all life. But let’s go beyond the science and have a look at natural experiment. We’ve had two natural experiments, global experiments, in the last 14 years. The first was in 2009, when the use of hydrocarbon fuels reduced in the recession that followed the global financial crisis. There was less carbon dioxide produced from the human use of hydrocarbons. What happened to the level of carbon dioxide in the atmosphere? It kept increasing. What happened in 2020, when we had a major recession, almost a depression, around the world as a result of COVID restrictions put in place by governments? We saw the same reduction in hydrocarbon fuel use by humans and the same cut in carbon dioxide output from humans, and yet carbon dioxide in the atmosphere continued to increase.

Those who understand the science understand that it is fundamental: humans cannot and do not affect the level of carbon dioxide in the atmosphere; it’s controlled by nature entirely. I’ve cross-examined the CSIRO three times now in the last few years. Under my cross-examination, which is the first of its kind in this country and the only one of its kind in the world, the CSIRO admitted that they have never stated that carbon dioxide from human activity is dangerous—never stated it. This is all rubbish that’s being talked about. Secondly, they admitted that today’s temperatures are not unprecedented. Thirdly, they never quantified, in three meetings, any specific impact of carbon dioxide from human activity. Never! That is the fundamental basis for policy. What’s more, they showed their sloppiness because they withdrew discredited papers which they initially cited to me at their choice as evidence of the unprecedented rate of temperature change and then failed to provide the empirical scientific evidence. They withdrew the two papers they put to me on temperatures, the two papers they put to me on carbon dioxide.

There is no danger. Temperatures are not unprecedented. We need to come back to the science, not the so-called experts the Greens talk about, not the pixies at the bottom of the garden. We need to come back to the science, the empirical scientific evidence, and base policies on that.

Questioning the Bureau of Meteorology at Senate Estimates

, ,

I’m down in Canberra at Senate Estimates this week. Over many years now I have consistently grilled the Bureau of Meteorology at Estimates over their methodology in ‘homogenising’ or changing raw temperature data. These changes include adjustments to make the recorded temperatures colder in earlier years and warmer in more recent years, making the supposed warming trend seem worse.

Transcript

Thanks Senator Green, Senator Roberts.

[Malcolm Roberts]

Thank you Chair. Thank you all for attending today. You got my questions in writing, Dr. Johnson?

[Johnson]

I did Sir.

[Malcolm Roberts]

The first question was please confirm whether you agree that any data adjustments need to be rigorous, independently replicable, and accurately supported with metadata.

[Johnson]

Senator, I might just ask my colleague Dr. Stone to take those questions. Thank you.

[Malcolm Roberts]

Sure.

[Dr Stone]

Yeah, thanks Senator.

[Malcolm Roberts]

Nice to see you again.

[Dr Stone]

Yeah, likewise The Bureau does agree that homogenization adjustments need to be rigorous and homogenization needs to be independently replicable using agreed peer reviewed methods, but it doesn’t actually need, it’s not a requirement that it’s supported by metadata as you’ve suggested. The purpose of the homogenization is to adjust for discontinuities where they’re detected, as I was describing earlier, in comparison with nearest neighbours. Metadata such as documentary evidence of a site move tells you that you might like to check for discontinuity, but it doesn’t tell you to make the adjustments themselves. So adjustment occurs only where a discontinuity in observations crosses what I referred to earlier as a threshold of significance. So it’s possible for homogenization to occur without metadata. And it’s also possible that metadata can describe a situation where there has been a change in observation practise, but homogenization isn’t required because that change doesn’t result in a discontinuity in observation. So it’s actually the discontinuity in observation that’s critical in the determinant of whether or not a homogenization occurs and the scale and direction of the change.

[Malcolm Roberts]

Okay, thank you. Moving on to some we’ve got data on many more which are similar, but the Townsville Weather Station according to the BOM’s metadata said it’s had one move. Whereas in fact, it’s had eight. The Rockhampton Weather Station has had according to BOM, one move. Whereas in fact, it’s had four. The Cairns Weather Station has had according to BOM. two moves the fact that it’s moved six times and the Chaliver Weather Station, BOM says it’s moved twice and it’s at four moves. Why did BOM and the various peer reviewers fail to detect and discuss these inaccuracies?

[Dr Stone]

Sorry, I missed the last part.

[Malcolm Roberts]

Why did the Bureau of Meteorology and the various peer reviewers fail to detect and discuss these inaccuracies in the metadata?

[Dr Stone]

Yeah, no, thank you. They’re not inaccuracies in metadata. So the metadata that either exists or it doesn’t, and in the cases you’ve described, there is instances where a shift in the med station has occurred and there’s not metadata that describes that. So it’s not actually in an inaccuracy in the metadata. And third of what I was saying too earlier, whether or not there’s metadata doesn’t impact on the integrity of their marginalisation process because it’s actually looking for that discontinuity in observations that determines whether or not there is a marginalisation that occurs.

[Malcolm Roberts]

That surely if there’s data about the movement of stations and that data is inaccurate, then the metadata is wrong.

[Dr Stone]

Now, in this case that the metadata is not present. It would be wrong if it said that there was a shift and there wasn’t one. What you’re describing is where a change hasn’t been recorded. So there’s not metadata that relates to it.

[Malcolm Roberts]

Right.

[Dr Stone]

There’s a difference.

[Malcolm Roberts]

So the BOM’s claim that has moved once in Townsville where the station moved once is not accurate because there’s no metadata on them?

[Dr Stone]

Sorry, we don’t claim it’s been moved once but we have metadata that shows that it was moved once.

Yeah. So we wouldn’t claim that there have I haven’t been shifted. We don’t have that data.

[Malcolm Roberts]

So you’ve got metadata for only one move. Whereas in fact, we know it’s been eight moves.

[Dr Stone]

We have metadata for Townsville. I’m sorry, I can’t tell you how many of those that we have metadata for but the principle remains the same. There are instances in the historical record where there’ve been changes made and they weren’t recorded at the time.

[Malcolm Roberts]

So what are the consequences of these areas specifically in terms of recording weather, data such as temperature?

[Dr Stone]

Yeah. I know there is. I just want to be clear about that. So the presence or absence of metadata, doesn’t imply an error.

[Malcolm Roberts]

If the station’s been moved and it hasn’t been noted in the metadata, then it’s not even recognised.

[Dr Stone]

Correct. But if we’re talking about the impact of that on the homogenization process, it doesn’t result in an error because the homogenization only occurs where there’s a statistical discontinuity in the data detected. So you can have moves that don’t result in homogenization being triggered, whether or not there’s metadata and vice versa. So it doesn’t be, I can be crystal clear. It doesn’t result in inaccuracies in the estimation of climate trends. If there’s metadata or not.

[Malcolm Roberts]

Has or not. Has BOM done any analysis to quantify the effects of the station moves especially the ones that it didn’t know about?

[Dr Stone]

No, absolutely. So, as I say, the process of homogenization actually looks back through the records for a given station, looks for discontinuity and measurements compared with nearest neighbours. So it steps through. And does that, so a high proportion of the homogenization changes that are made aren’t triggered by metadata they’re triggered by, as I mentioned, a discontinuity in the observations. And that’s determined by comparing with a large number of nearest neighbours, which we can do with temperature because temperature is reasonably conservative across geographic space. And it’s why, for example, you can’t really homogenize for rainfall because it’s much more spatially viable.

[Chair]

So do you have anymore questions Senator Roberts.

[Malcolm Roberts]

Yes. I’ve got a couple of more questions, Chair. You said you’ve been able to analyse these past records. Could you please provide for each of the four sites that I’ve mentioned that’s Townsville, Rockhampton, Cairns, and Charleville the quantified analysis that Bureau of Meteorology has done and document the independent peer review process used just on notice, please.

[Dr Stone]

That’s all on the website. Yep, no problem.

[Malcolm Roberts]

Thank you. Last pair of questions, Chair. What are the specific quantified consequences of BOM’s inaccuracies on CSIROs use of BOM data? I’m particularly interested because CSIRO has admitted to me that it does no due diligence of its own on temperature data that it merely accepts from the Bureau of Meteorology.

[Dr Stone]

Yeah. Thanks for the question. As I described, the presence or absence of metadata doesn’t result in inaccuracies in the homogenization process. So inaccuracies have not been passed on to CSIRO or any other user because of concerns about metadata. It’s fundamentally a statistical process.

[Malcolm Roberts]

What are the consequences on the government policy and the general assumption that Australia temperatures are increasing?

[Dr Stone]

Yeah. As I said, so if the question is about the accuracy or otherwise of the estimates, presence or absence of metadata isn’t material. And, you know, I can confirm the global trend for warming is around 1.1 degrees Celsius since the pre-industrial period.

[Malcolm Roberts]

And when you say pre-industrial, what year?

[Dr Stone]

1850.

[Malcolm Roberts]

Thank you.

[Dr Stone]

And–

[Malcolm Roberts]

It’s just at the end of the little ice age.

[Dr Stone]

What I’m seeking to do is describe the difference between the global trend, the homogenized trend and the raw observation trends. So the global trend is around 1.1, the unadjusted trend is 0.95 Degrees Celsius plus or minus 0.24 over the same period. And the homogenized trend is 1.44 plus or minus .24 So neither the raw nor the homogenized trend differ from the, significantly from the estimate of the global trend.

[Malcolm Roberts]

Okay, thank you. Are you aware just by coincidence that CSIRO has admitted to me that today’s temperatures are not unprecedented? And then after it admitted that it said that what is unprecedented is the, they claimed is the rate of recent rates of temperature rise. Yet the papers they gave us, not one of them shows that. And two of the papers show that past temperature rise, rate of past temperature rise has been warmer than the recent temperature rise which ended about 1995.

[Dr Stone]

Yeah. Thank you. I haven’t seen the CSRO papers or–

[Malcolm Roberts]

We’ll have to have a chat.

Thank you.
