Latest / Cultural Wars | America Out Loud News / Is Canada basing its climate policies on ‘decision-based evidence-making?’
Transcript
- 0:07Mainstream media has betrayed our trust.
- 0:10Rather than tell us the whole story about the important issues of the day, they tell us only what they want us to hear.
- 0:16Your hosts, Tom Harris and Todd Royal will bring you the other side of the story.
- 0:27Like many nations across the Western world, Canada continues to spend hundreds of billions of dollars trying to stop climate change and getting ready for supposedly dangerous global warming.
- 0:39This makes no sense, of course.
- 0:40Warming has generally benefited humanity.
- 0:43And no nation, let alone Canada at only 1.5% of world emissions can stop climate change.
- 0:50It's been going on since the origin of the atmosphere billions of years ago.
- 0:54The only constant about climate is change.
- 0:56It changes all the time, no matter what we do.
- 0:59And if you were concerned about emissions, if Canada disappeared completely, China and India together emit one year's worth of Canada's CO2 emissions in less than two weeks.
- 1:16There are many drivers of this ridiculous crusade, but one of the main ones is that Canada is supposedly warming twice as fast as the global average.
- 1:25Indeed, that claim has made Canada the poster child of global warming for the United Nations and other institutions to site.
- 1:33The federal government, in particular, Environment and Climate Change Canada is the main source of this claim, one that's been endlessly repeated by mainstream media and politicians and is now quoted as part of the rationale for the climate change master plan in cities like Ottawa and Toronto.
- 1:51But what if the claim about Canada's rapid warming is not supported by sound science?
- 1:56What if the temperature data that is fed into the computations is corrupted by artifacts such as changes in the instrumentation or changes in the environment around temperature stations?
- 2:08And what does this say about the reliability of the so-called global temperature that has led the world to now spend five billion US dollars a day on climate finance to discuss his findings that most of Canada's warming over the past six or seven decades is apparently not real?
- 2:27We've invited Dr.
- 2:28Joseph Hickey, a data scientist with a PhD in physics in complexity science in particular to be our guest today.
- 2:36Dr.
- 2:36Hickey is the author of an important report that was published on December 23rd, 2025, titled Artificial Stepwise Increases in Homogenized Surface Air Temperature Data invalidate, published Climate Warming Claims for Canada.
- 2:52After completing his doctorate in physics at the University of Calgary, Joseph worked as a data scientist at the Bank of Canada and completed a postdoctoral fellowship at the University de Quebec at Trois Rivier.
- 3:06He's now president and associate researcher at Correlation Research in the Public Interest, a registered not-for-profit corporation based in Ottawa, Canada.
- 3:16So welcome to the show, Joseph.
- 3:18Hi there.
- 3:19Thanks for having me.
- 3:20Yeah, thanks for thanks for being here.
- 3:22Um you did a paper uh that that was uh artificial stepwise increases and homogenizes surface air temperature data and validate that's a key word here and validate published climate warming claims for Canada.
- 3:37Maybe we can get to do one of these for the United States.
- 3:40Can you tell us about correlation research in the public interest?
- 3:44Yes, that's our research organization.
- 3:46It's a registered not-for-profit organization in Canada, and we we do um research on topics of public interest.
- 3:55Uh, a lot of our work has focused on COVID topics, but we're also interested in climate change and and other uh topics as well.
- 4:03Wow.
- 4:04Um Canada and you know, there's so much between Canada and the United States now, but you certainly have a very pro-climate change, pro-global warming prime minister certainly has in the past.
- 4:17But we keep hearing these things with Canada that supposedly you're warming twice as fast as the global average that supposedly Canada is the poster child of global warming for the UN and other institutions to cite, and that the Federal Department of Environmental and Climate Change Canada is the main source of this claim.
- 4:37And I think now we even see, and Tom, correct me here, there it's become this rationale for climate change master plans in places like Ottawa and Toronto.
- 4:47Can you talk about this?
- 4:49Is Canada warming faster than the global average?
- 4:52And you know, is that the reason guys like Mark Carney get elected?
- 4:56Well, here's um what I uh the report that I have just uh put out with correlation research in the public interest uh a couple of weeks ago looks at the station level data, temperature data.
- 5:11So the data for individual weather stations um that is uh publicized, made publicly available by Environment Canada, which is now officially called Environment and Climate Change Canada, as you mentioned.
- 5:26And what I find is that in many, many stations across the country, when you look at the annual mean temperature, there is a large stepwise increase in the year-to-year uh temperature from one year to the next in 1998.
- 5:44And this kind of a large one-degree uh discontinuity in the temperature record is something that is always treated as an artifact in uh in temperature records in long-term temperature trend analysis, and that and this is because it's recognized and accepted by climatologists that any time you have a weather station that has been recording temperature data over decades, there are going to be what are called inhomogeneities.
- 6:13There are going to be breaks in the data, and it might be because the station has been re relocated at some point in time, um, which can be you can change its altitude, it can change it can be moved uh up to uh some number of kilometers uh away from its original site.
- 6:30The instruments change, which can introduce uh uh either sharp discontinuities or it can be more gradual biasing factors.
- 6:38And uh the other big category of changes are are what are called observational changes, uh things such as the time of day at which you record the minimum or the maximum uh temperature using the uh the thermometers that capture the extreme uh temperatures.
- 6:53So these different types of changes are really well known.
- 6:56Um there's there's lots of them.
- 6:58And so climatologists and scientists working at the National Meteorological Institutes, like Environment Canada and Canada, um, spend a lot of uh time and and put a lot of effort into trying to adjust the records to to try and remove these biasing factors to correct the steps that are that are known to uh to oh to pretty much always be present in any weather station that's been recording uh temperature over several decades.
- 7:26So Environment Canada is seen as being one of the highest quality uh data sets in the world, is is the one that Environment Canada produces.
- 7:34It's called the adjusted and homogenized uh Canadian climate data.
- 7:39And so this is the data set that I used.
- 7:41It's supposed to uh have be state of the art uh in terms of its corrections that it's done.
- 7:47It's it's they've prepared the data and they've put it out there and promote it for long-term temperature trend analysis.
- 7:54But when you look at it and you you take the annual mean temperature, which is a good thing to do because the the raw data is daily data, but if you average over the year, then you remove the seasonality in the data.
- 8:06Yeah.
- 8:06So it's a good thing to do is to look at the annual averaging and how that those have evolved over time.
- 8:11And what you find is that there's a large stepwise discontinuity, exactly the kind of thing that is supposed to have been removed from the data that is present.
- 8:20Uh and and then if you'd correct for that one degree step, the result is that it removes essentially all of the warming for Canada over the past seven decades, which is the period that Environment Canada uses to do it's long-term uh okay.
- 8:38Okay, you I'm sorry to interrupt.
- 8:40So when I ask you the question, the first thing that came to my mind and Tom as well is every time I talk to Tom, I'm here in the Dallas, Texas area.
- 8:48It is literally 75 degrees here today.
- 8:50We're having a very warm winter.
- 8:52Every time I talk to Tom, or I'm sure you, you're caked in snow, playing hockey on snowmobiles, you know, you're you're in your gigantic coats and there's a massive snowfall.
- 9:03When I hear that it's warming in Canada, I think this is where the ridiculousest of all this comes because I start to go, well, where's the common sense in all of this?
- 9:13Because we as an American in the southern part of the United States, how is Canada warming when every time I say Canada, it seems to be snowing?
- 9:25And I'm being a little ridiculous here, and I understand I'm being a little fun here with you, but did people ever pose those questions to you when they go, um, Dr.
- 9:35Hickey, you're really smart in this, but I'm just going to use a little common sense to go.
- 9:39My my cousin Ethel up there in Canada every second I call her at see her on you know Zoom or FaceTime or visit.
- 9:45She's freezing cold, but you're warming.
- 9:48Huh?
- 9:49Help explain.
- 9:50Absolutely.
- 9:51If I could show you uh what it looks like outside the window, you'll see a lot, a lot of snow here in the Ottawa area.
- 9:59And
- 10:00And um, you know, we have a uh 10 kilometer long skating rink called the Vido Canal, and it's open uh already uh pretty early in the winter, and uh so yeah, no, it's it's certainly it's cold here, but but what I wanted to do is uh look at the data itself, you know, the what's supposed to be the best quality data.
- 10:20Yeah, and um what you do when you find that is that all of the warming that's calculated for Canada by Environment Canada um disappears once you remove this step that occurs in 1998, which is widespread across the country, it's in most of most of the country.
- 10:37There's the Western province of British Columbia does not have this feature, and there are some other stations in uh also in the West in Alberta and some in the north that don't have it, but otherwise it's pretty much this this feature is pretty much widespread across the rest of the country, which is uh the country that's the size of some continents, it's a large uh country.
- 10:59And um yeah, so that this is essentially uh the the main focus of the paper.
- 11:05Yeah.
- 11:05Now, when did you first become aware of this?
- 11:08Because it's it's a pretty big problem.
- 11:10You think the uh environment climate change Canada would have noticed it themselves.
- 11:16Right.
- 11:16And so I was working as a data scientist at the Bank of Canada, which is the central bank in Canada.
- 11:22So it's a crown corporation, it's uh a government agency essentially, a government institution.
- 11:28And um I was asked to do analyses of temperatures because the bank wanted to see if um there were correlations between changing economic activity and climate variables such as temperature precipitation, uh so on.
- 11:45And so I took the task very seriously, and I said if I'm going to, and I'm a physicist, and if I'm going to be studying the temperature data and using it to compare with economic uh data, I need to understand the temperature data.
- 12:00And I need to check the quality of the data and see if it's uh if it's if it's valid, if it's usable in this way.
- 12:09And so I did some various uh checks, and what I after exploring several different things, what I came to decide was a good high level or first approach check on the quality of the data was to do these annual averages of of the temperature for individual stations.
- 12:28And that's what led me to seeing this it jumps out when you see it.
- 12:32The the data is fluctuating around a plateau annual average temperature over the years, and then suddenly in 1998, it jumps up to a new plateau one degree higher, and then continues to fluctuate around that new plateau.
- 12:47So it's a step, if you think the data is flat, and then it steps up to a new plateau and it stays flat and at the new uh plateau.
- 12:56And so this is the kind of thing that this is does not seem to be natural climate variability when you look at it.
- 13:03It's not it's not a slowly increasing trend.
- 13:05And so I asked Environment Canada what was going on with this and how would they explain that.
- 13:13And I wanted to see if they would have an explanation that would allow us to continue working with that data as is, or whether it would need to be corrected before we could do the work that we wanted to do, comparing with the economic uh data.
- 13:26And the answer from Environment Canada, which uh those emails are in my report because I uh since uh that time I uh accessed these emails through access to information.
- 13:40So they're um part of the public record now.
- 13:44Uh they're in my report, which is on Correlations uh website, and you can see the responses of the senior Environment Canada climatologist, Lucy Vincent, who at first um said that she quickly checked the metadata for several stations and could not uh find any notes about switches to automation, which is something I had suggested might be a reason for this uh this feature, this step, because it's in some of Environment Canada's articles, they mentioned that many stations were undergoing the change to automation in the 1990s, and then I responded with a detailed article where I reviewed many different types of biasing factors, and there've been observational and experimental studies that have been done over the years comparing things like um what happens when you change the instruments from the old types of thermometers to the types that they use uh in automated stations, or another important feature is the screen that protects the thermometer from solar radiation.
- 14:48What happens when you change that screen, or when the um reflective coating on the screen wears off over time, and so that the screen gets uh heated up more by the solar radiation.
- 15:03These are important effects that can uh cause biases of uh often around half a degree, it can be up to more than a degree or one or two degrees depending on the study, and depending on the uh the location and the climatological conditions that the instruments are in.
- 15:20And so I I included three large tables in my email to the Environment Canada researcher Vincent uh explaining how there could be many different types of biasing factors that could be responsible for this kind of uh discontinuous break at 1998.
- 15:36And the uh response was basically to brush me off and to say um we have not detected uh shift um that you that you the one that you've seen visually at 1998, because I had sent her graphs, but she so she used the word we have not detected a shift, and our results are in line with results from around the globe, which is this was the way that she answered.
- 16:01Now they the use of the word detected in her response is quite interesting because when you look at Environment Canada's articles presenting the adjusted and homogenized data set, which were authored by Vincent and co-authors, you look at their article, but they explain the method they use to detect these kinds of steps, like the one that I that I noticed.
- 16:22And the method is based on comparing pairs of stations that they call neighboring stations, and they can be often in different cities, they might even be up to a couple hundred kilometers apart, but they call them neighboring stations.
- 16:36And the idea there is that if a step occurs at one station due to changing the instruments, for example, or removing the station, they would do not expect to see it at the neighboring station.
- 16:48And so by comparing the two records, taking the difference of the two records, you will see the step showing up using doing that comparison.
- 16:57Now the problem with that is if the step occurs the same step occurs at both stations, then you don't detect it with their method.
- 17:05When you take the difference in the two records, since they both have the step, the step disappears uh in their in their method.
- 17:14And and I show in the report, I show how that's the case.
- 17:18And it turns out that in their article, they included a figure showing how they do their detection method where they happen to have used two of the stations, Moncton and New Brunswick and Frederick, New Brunswick, that have among the most striking examples of this step.
- 17:34And so it disappears.
- 17:36It disappears because you subtract it one from the other.
- 17:40So that I thought was quite interesting that uh she used the the word that she had not detected a step when you look at what that actually means.
- 17:50Uh that's not an explanation for this.
- 17:53Yeah, in the in the notes, in the notes under this interview, when it goes up on Monday, I'll put up some samples of the graphs where you show T min and the map minimum temperature T max and average, and you can see the big jump.
- 18:06It's huge.
- 18:07I mean, you know, they're they're measuring to tenths of a degree, and they have a sudden jump of a degree, like wow.
- 18:15Do you feel the research is shoddy?
- 18:17Because just listening to you right now, this you know, some people would go, oh gosh, there's a bias here.
- 18:23So you're wanting to show a bias to warming so I can whether more government control, more money towards renewables, hurting the fossil fuel industry, etc.
- 18:32But do you on just kind of a granular level though?
- 18:35Did you find when you're reviewing things, do you find the work and the research just to be shoddy work?
- 18:42Because that's what it sounds like.
- 18:43Lazy in some ways.
- 18:46They do an enormous amount of work, and they um are producing a product that has to have certain features that they that they're looking for that they that they have criteria for.
- 18:59But I think that this glaring one degree stepwise increase in most of the stations across Canada absolutely needs to be addressed.
- 19:11It's it hits you in the face when you see it.
- 19:14I I put it to that to the senior person at Environment Canada who's been intimately centrally involved in producing these data sets for 30 years since the early 1990s and knows all the ins and should know all the ins and outs of it.
- 19:30And she was not able to provide uh an answer.
- 19:34So that is something that's still unaddressed.
- 19:38The this data set goes through different generations, they called it when they update their procedures they use to do their adjustments or they include new stations and so on.
- 19:48And the fourth generation was released in 2025.
- 19:53So very recently.
- 19:55And there's that when you look at that fourth generation, it has exactly the same problem.
- 20:00Problem as the data set that I was using back in 2021.
- 20:03And so they have not done anything about this.
- 20:05And yet you pointed it out to them back in 2020.
- 20:092021.
- 20:10Oh, okay.
- 20:11Wow.
- 20:12Like the one degree thing, I'm sorry.
- 20:14I'm just I'm just stunned of like that.
- 20:17That's that's that's glaring, but it's also stunning.
- 20:20What do you Tom?
- 20:21What do you think about that?
- 20:22Well, it it erases most of the warming.
- 20:25And uh Joseph, you were saying that after that step, the overall trend is negative.
- 20:31It's actually cooling since 1998, you know, in on average across the country.
- 20:37Right.
- 20:37And it's not just that if you're correct for this one degree step, it's not just that it removes most of the warming, but what it does is it produces a time series where there's no statistically significant trend.
- 20:49So that means it reduces all of the warming statistically speaking.
- 20:53Joseph, catch you a little bit on the on the research.
- 20:56So these data sets, and pardon me for being a little boring to the audience and to Tom.
- 21:02I'm assuming you're getting these data sets in an Excel spreadsheet.
- 21:06Yes, more or less, yes.
- 21:08Okay.
- 21:08So in other words, it's um people who do Excel or to explain data sets.
- 21:14It's just long columns of information, which if you understand basic sorting of an Excel spreadsheet, you can go through and look at the data.
- 21:24I think that's where I keep coming back to this feels like something's been manipulated.
- 21:28I've had to deal with data sets before.
- 21:31And when you have gigantic trends like with what you're talking, uh give a little background, Joseph, I've done things like uh economic clustering, you produce heat maps, where's where's companies located?
- 21:43You can easily find in a data set.
- 21:45Oh, there's a lot of um financial firms in Toronto versus Ottawa, you know, something like that.
- 21:53So is that what you were finding sometimes like these Excel data spreadsheets?
- 21:58Because I I really am.
- 21:59I'm a little uh I'm dumbfounded of how someone doesn't get it's one thing in a view to go, oh, it was like zero point one, but a degree that that's the data.
- 22:10It's discerning to me.
- 22:11The underlying data that that environment Canada provides is for a specific, well, for a station.
- 22:18Um, you know, it can be Toronto, Canada at the airport, and it's the daily mean temperature, the daily maximum temperature and the daily minimum temperature.
- 22:31So you can take any one of those, you have the data for every day, unless once in a while there's a missing day day, but otherwise you have the data for every day um for many decades, and then you can do things like take the annual average and then make a plot.
- 22:45Right.
- 22:46So now the data is um very you could say manipulated, very adjusted.
- 22:53And there are a lot of manipulations that are made to the data, and the government is open about that.
- 22:58They they show what the raw data looks like, and then they show what the adjusted data looks like, and you'll see that they've shifted the whole series up, for example, because uh one of the main reasons is that because they changed the observation time for the minimum and maximum temperatures in 1960 or 1961.
- 23:19Um that introduced what they find is a cooling bias in the data.
- 23:26And so for that reason, they believe um that they need to shift the series up to higher temperatures.
- 23:36Uh now this I'm sure they do.
- 23:38I'm sure they do.
- 23:39This this kind of adjustment causes some interesting problems.
- 23:45And that was another kind of a side point that was in this article is that in the access to information emails that I obtained, there were emails from another Bank of Canada employee with Environment Canada, where he had noticed.
- 23:58Um, and his name is Julian McDonald Guimont, and the emails are in the in the report.
- 24:02And he noticed that he had found 10,000 different instances where the minimum temperature for the day at a particular station was greater than the maximum temperature.
- 24:17Wait, wait, wait, wait, wait, come out.
- 24:19Sorry.
- 24:20I'm gonna be I'm gonna be today's uh LUDE here.
- 24:23Um the minimum temperature was more than the maximum temperature.
- 24:29That's not it, it sounds like a lot, and it is I mean, it is uh uh 10,000.
- 24:34But of course, this is we have hundreds of stations, and we have 365 days a year.
- 24:40And so this is the 10,000 instances only represents about say one percent of the data.
- 24:46So overall it's it's small, but it does show it's something that is uh it does show the kind of effect that their adjustments can have.
- 24:57It can have these kind of absurd effects because um they've done things like raise the minimum temperatures because they've decided that there's a cooling bias for XYZ reason.
- 25:08They raise the minimum temperatures across the board, and it can produce these kind of absurd situations where now all of a sudden the minimum is greater than the maximum.
- 25:17So um that's that's just I mean, there's lots of lots of things like this that can happen, and that's just one that where it's concrete.
- 25:26Um Mr.
- 25:28McDonald Guimont had created a table with all 10,000 examples, and he and he sent it to Environment Canada.
- 25:34Uh and said, please, what's going on here?
- 25:36Can you have it?
- 25:37And I and I'm sorry to keep harping on this, Tom, and and feel free to cut me off here, but it's it's not the hardest thing in the world to take all this data, put it in Excel, begin to do your arithmetic of the three different temperatures.
- 25:52You know, someone like you, Tom who understands this, or you, Dr.
- 25:54Ricky, backwards and forwards.
- 25:57Um, sort it properly, do some some, you know, let it do the the basic arithmetic, and you begin to you can find all these discrepancies.
- 26:06This this is not hard.
- 26:08My god, with AI now, you could certainly throw it in there.
- 26:11I think it just it boggles my mind because it's so destroys institutional trust.
- 26:18That's what you're in my mind what you're doing is destroying institutional trust.
- 26:22And when you work within one of these institutions, government institutions, there's an enormous amount of pressure to accept the environment Canada data as being high quality data that you can use out of the box.
- 26:35And if you start to question it, it's you basically are encouraged not to go down that road pretty strongly.
- 26:40So, but but at the same time, well, Environment Canada promotes that data for use in long-term temperature trend analysis, but they also have disclaimers where they say things like use this data with caution.
- 26:53Um because they know that there are a lot of um biasing factors that can affect the data, and they've tried to they say that they've tried to correct uh many of them, but they they even like they cannot catch all of the biasing factors.
- 27:11There are a lot of factors that are gradual that that can affect the record at the station over many years, like it can be like the growth of trees in the vicinity of the thermometers, can apply a gradual, maybe it's maybe there's more shade that's the the thermometers in the shade for more time out of the day as the tree gets larger.
- 27:31There are many factors like this.
- 27:32Uh the um irrigation methods that are used on the land around the thermometer, the thermometer um crops that might be growing nearby, um forest fire management practices that allow forests to grow, whereas in the past there would have been less forests in the area around these different there's many different things um that can that can impose a gradual bias that is very difficult to detect.
- 27:59Um there might not be any history at the station.
- 28:02Sometimes they have metadata notes about what happened at the station.
- 28:05So it's the climatologists know that that there are there are many of these biasing factors that can affect the data, and they tell the community, the research the the public to use this data with caution.
- 28:17Um, but that's not what happens when there are headlines all over the place, and even you know, in other countries, that Canada was warming twice the global average.
- 28:29Unfortunately, we have to go for a break now.
- 28:30We'll be right back with Dr.
- 28:32Joseph Hickey, a data scientist with PhD in physics whose focus is on complexity science, and we're learning that some of the data from Canada, the supposed poster child of global warming, may not be trustworthy.
- 28:46So stay tuned.
- 28:46We'll be right back after the break.

- 33:18If we are back, we're back with Dr.
- 33:20Joseph Hickey, which this is an absolutely fascinating conversation.
- 33:32But did you find within these data sets?
- 33:34And just remind everybody, it's just going to be long rows of data, generally in an Excel spreadsheet.
- 33:40Well, what you can do with that is run regressions to distill it down even further and even try to detect bias or detect causation or correlation.
- 33:49Did you even did you run regressions to even kind of distill the information down to the truth even further?
- 33:58Yeah.
- 33:58So I looked at um trend analyses for individual stations.
- 34:05And this is something that Tom was mentioning a moment ago, and it's in the report is that when you look at the trend for 1998 to 2018, so the 20 years after the the break that happens at 1998, what you find is that if anything, the trend is negative and the temperature overall is decreasing.
- 34:27And uh however, it's either negative in many cases or uh statistically insignificant.
- 34:35So that's to say that there's no evidence for warming over the 20 years after this break in the data that I've been talking about.
- 34:43Sorry, and as you take out the step, the warming for 70 years disappears.
- 34:48Well, that's right.
- 34:49That's the other thing I was going to mention is that when Environment Canada makes a statement about the temperature trend for all of Canada, they use a gridding procedure and they do averaging over space and they come up with a single time series that's supposed to represent the whole country.
- 35:07And when you look at that figure in their paper, you see this 1998 step again.
- 35:13And so what I did was I digitized the data from their figure, which is easy to do now.
- 35:18Uh there's online tools to do that.
- 35:21And I reproduced their trend analysis for their figure.
- 35:26And then I corrected the 1998 one degree step increase, removed that, and applied their their trend analysis to that corrected data.
- 35:37And when you do that, there's no statistically significant trend.
- 35:42So that's why that's the kind of analysis that's in the report.
- 35:45You can read about it, but that's why when I say that if you correct this for this 1998 step, there's no statistically significant warming uh for Canada.
- 35:53So yeah.
- 35:55My mouth is hanging open here at people know statistically insignificant means there's not even there's not even a number there.
- 36:04I can get into very boring things called confidence intervals, but when he's saying it's not statistically even significant, there's nothing to measure there.
- 36:12That's what he's really doing.
- 36:14It means in that corrected data, there's there's no warming.
- 36:16There's no evidence of warm.
- 36:17Yeah.
- 36:18I'm sorry, Tom, please you.
- 36:19But sorry, I didn't want to mention, I wanted to mention in this about about this one degree step increase, is that when you look at Environment Canada's papers that they've put out over the years, you go back to when they were first creating these adjusted and homogenized data sets, and they describe you know how in the records for weather stations, there's often these step discontinuities, and they need to correct for them.
- 36:45It might be because they moved the station or change the instruments.
- 36:48And what they say is when whenever we look at a temperature record and we see a step that's greater than 0.6 degrees Celsius, we always correct for that, even if we have no documentation at the station about what might have happened, there's no history.
- 37:06Um we're gonna automatically adjust for that.
- 37:10And that was back in 1999, and that's Lucy Vincent uh saying that in her in her article with her co-author.
- 37:18And that's the same researcher who um about 20 years later in 2021.
- 37:23I emailed and I showed her the one degree step increase in all these stations and asked what's going on, and and basically she attributed it to natural climate variability.
- 37:33Even though she had done the research to say it couldn't be at that point.
- 37:38That's right.
- 37:38In 1999, the procedure was that those steps definitely would be adjusted.
- 37:44So uh, even without any documentation, any any history to uh explain why the step might have happened.
- 37:52Now, if this dramatic stepwise increase from one year to the next from a low plateau to a high plateau, if this is natural climate variability, then this is not something that's compatible with carbon dioxide forcing.
- 38:07Uh you don't have there's no model that predicts that with a gradual accumulation of of CO2 in the atmosphere that suddenly the the annual temperature would jump up by one degree and stay at that new plateau for years uh following it.
- 38:24So and the and the other aspect of of that side of that way of thinking about it, is that if Canada has undergone a stepwise increase from one year to the next and its overall temperature, and that's something that's not compatible with carbon dioxide, then why wouldn't you find that similar kind of phenomenon around the world uh in Europe, Asia, United States?
- 38:52If this kind of thing can happen in Canada, then it must be so it would not be something that has only ever happened in Canada.
- 38:58And so it would be this kind of regime shifting of very very abrupt change in annual average temperature would be something that happens in other places in the world.
- 39:09You'd have to then presume that it would be responsible for the warming all over the world.
- 39:13So you see it, especially in border cities where there would be some sort of relationship between Detroit and Windsor, but you're saying it's not in the American data.
- 39:24Uh well, you know, I I've only looked quickly at the American data since putting the report out, and it does look like there could be some something similar in the American data.
- 39:35Oh, is that right?
- 39:36And now that I think it and I haven't looked in in detail at that, but I would like to do that.
- 39:43Uh the border locations.
- 39:45Yeah.
- 39:46Yeah.
- 39:46Now it strikes me that if they put in 72 Canadian reference climatological stations, they added those to the global climate observing system in that exact year.
- 39:57Isn't that the most probable cause?
- 40:00Because some of the other things you were listing were gradually thing, you know, gradual changes in environment or whatever.
- 40:06If for it to occur exactly in the year where they added these new stations, isn't that most likely a major cause?
- 40:14I think that's a really good hypothesis.
- 40:16I think that it's very possible that given that there was a plan uh to add a large number of stations around the country to the global network for the first time.
- 40:27This is a new global network, and it was going to be Canada's entrance into this important global network.
- 40:32There would have been an uh a governmental uh push to make sure the stations were at a certain say level of quality or uh meeting certain kinds of standards that might have this is this is speculation, but that might have involved um upgrading the instruments, so in other words, changing the instruments that might have been done very quickly within the span of a year across many countries, uh sorry, many stations in the country, in order for the government to be able to say, okay, now we're up to snuff.
- 41:04We have we have the latest and greatest uh instruments and uh um instrument housing apparatuses and so on at the stations across the country, and now we're ready to join uh the global network.
- 41:18That's that's that's that's plausible.
- 41:20I would like to look at the metadata they call it, which is the data that Environment Canada has uh includes notes on the history of the stations and when things have changed and so on.
- 41:32I did ask for that data when I was working at the Bank of Canada, and actually that email just happens to be in the access uh to information request, and um I was told that the data is not in a um easily accessible format and not publicly um available, something like that.
- 41:52So I think that that that data should be available to the public, but uh it's definitely not it's not easy to get your hands on it.
- 42:00Um so that would be interesting to look at the station history and and see if there's some notes about uh a change that might have happened at that time.
- 42:10Yeah.
- 42:11And and they still haven't answered your December 23rd report.
- 42:15No, there's no there has been no uh comment uh so far on that.
- 42:19Yeah, yeah.
- 42:20I I I imagine they're hoping that may mainstream media don't pick this up because then they'll be forced to reply.
- 42:28Yeah.
- 42:29Yeah.
- 42:30I I you know I've I'm just I don't know, I'm simply stunned.
- 42:33I would like to ask you just after the little bit of the American records that you've looked at.
- 42:40Do you feel comfortable even making a comment on a little bit of what you found so far?
- 42:45If you don't that's okay.
- 42:47The only thing I've looked at so far is a overall uh time series for the United States, and it does appear that there could be a um a step increase at 1998 in the American national level time series that the government produces.
- 43:03It it doesn't it's not as striking in the sense of it's not going from a low plateau stepping up to a new high plateau and staying there, um as you see in for the Canadian stations and even for the all Canada time series.
- 43:17Um so I need to look at individual stations in the United States, which I haven't done yet.
- 43:22It's a good thing that you don't work for the Bank of Canada anymore because when you were working for them, that was essentially working for the government.
- 43:29So you couldn't just jump out and put out a report like you did on December 23rd well that's uh no that's right.
- 43:38That's right.
- 43:39Um that uh I guess they were hoping you'd you'd work for the government forever and you can keep it a secret.
- 43:48Yeah, they should have given them a raise, you know.
- 43:51Give this guy a million dollars to keep him in the government.
- 43:54He's been running the Bank of Canada right now, then none of this would come out.
- 43:58Yeah, so so all the information you have in your report, it's there, it's valid, it's it's legal, it's legitimate for you to share this information.
- 44:07That's right.
- 44:07It's uh the emails are all um any anyone can access them uh through access to information.
- 44:14Um it's a you know program that in Canada where you can access uh government emails and other documents, and um so any anybody could get uh these emails themselves and see them, and the data itself about the temperatures is publicly available, and uh so this is all uh in the public realm.
- 44:36Do you know off the top of your head then what fraction of the supposed warming in the past 70 years?
- 44:42Do you think if it's just an artifact of the data instead of actual real warming?
- 44:47Well, if if we're talking about the warming for the all of Canada, which is uh yeah, the the main thing to look at, um Environment Canada does that from 1948 to 2018 or to the to the latest year, um, which now would be more like 2024.
- 45:05But uh in the in the paper that um I was using they go up to 2018, and that's because that's what was available when I started doing this in 2021.
- 45:16Um if you do that, you find and you apply their trend environment Canada's trend analysis method, you find an increase of 1.74 degrees Celsius from 1948 to 2018.
- 45:30Okay.
- 45:31And then if you correct for the the one degree step increase at 1998, you find a 0.29 degrees Celsius increase, but it's not statistically significant.
- 45:44Right.
- 45:44Now that's important because what the error bars when you look at them over the whole country is as big as 20.29.
- 45:51Um there's a certain statistical significance test that is used.
- 45:59And you know, when you apply that test, it's called the Mandels uh Tau test.
- 46:05It's the one that they use at Environment Canada.
- 46:07When you apply that, and and you when you when you use the data that they show in their graph that does have the step in it, you get the 1.74 degree increase, and it is statistically significant according to the test.
- 46:20But when you remove and you had you remove that step, you redo the analysis, leave the data exactly as is, except for removing the step, you get 0.29 degree Celsius increase, but it's not statistically significant according to the same statistical significance test.
- 46:36Wow.
- 46:36Wow.
- 46:37You know, it's it's interesting that various municipalities it means that it's indistinguishable from zero.
- 46:43Okay.
- 46:44It means you can't the chances that uh that that slope that you calculate is actually different from zero is very low.
- 46:54That's in a nutshell what it means.
- 46:56Wow, wow.
- 46:57Now you have various um municipalities like ours, because you're in the Ottawa area as well.
- 47:02Um City of Ottawa, you know, city of Toronto, they use the claim that Canada is supposedly warming it twice the global average as a major part of their rationale for multi-billion dollar climate change plan.
- 47:15So what sort of message would you give to these councils that maybe they should sort of back off a little bit until this issue is resolved?
- 47:23Well, I look outside and I would say don't cancel your snow removal budget.
- 47:27That would be the first thing, which is significant, of course, for a city like Ottawa.
- 47:34But um, no, I would say they need to look at the data.
- 47:39They need to have someone explain to them what this data is and how it needs to be interpreted, and uh how you need to work with data like this and and check the quality of it, and ask them what is their their paradigm about uh this this uh supposed warming that's happening.
- 48:00Is it something that happens all of a sudden in one year from one year to the next, and then you don't see any more warming after that?
- 48:06Is that the model that they have in mind that that all the warming occurred in in one year?
- 48:12Um I don't think it is.
- 48:14And and so they need to be exposed to some cognitive dissonance.
- 48:19Uh yeah.
- 48:20Because in Ottawa's case, they're showing a 1.8 degree rise over, I think it's like 60 years or something.
- 48:27But in reality, it's much less.
- 48:30Well, in reality, um, and I haven't done the analysis for Ottawa specifically, but um you remove the uh there's no statistically significant trend when you do it for Canada.
- 48:42So it's it's it's not just much less, it's that there is no evidence of warming.
- 48:48Yeah.
- 48:49Um, Canada's a huge country, so so our temperature measurements must have a significant input to the world average.
- 48:58Have you figured out you know, first of all, let's assume every other country was perfect and only Canada had this problem.
- 49:05Would it noticeably affect the world average?
- 49:09Well, I would look at it a different way.
- 49:12I would I would say this is um something that is always considered to be an artifact, this kind of discontinuity.
- 49:21When you correct for it, there's no warming for Canada.
- 49:25And so you have to then question whether biases and artifacts are being selectively retained in these data sets, and and does that apply across the world?
- 49:39And then if, on the other hand, a sudden abrupt change in the annual temperature from one year to the next, if that is natural, then that is not compatible with carbon dioxide forcing.
- 49:52And that would have to be occurring in other parts of the world.
- 49:56So, in other words, if it is natural in Canada, then it's
- 50:00It's probably explaining warming all around the world.
- 50:03And it's not something that's related to CO2.
- 50:05Because that's just not how there's no the paradigm of CO2 if influence on temperature works.
- 50:12So either it's an artifact, which is what scientists would always have assumed in the past for these kinds of abrupt changes, or it's something that's not compatible with CO2 and should be widespread because it can't just occur in Canada and only Canada.
- 50:27Yeah.
- 50:28Exactly.
- 50:29Yeah, you know, it sounds to me, you know, they always talk about evidence-based decision making.
- 50:34It sounds like decision-based evidence making.
- 50:37You know.
- 50:39Well, yeah, that's good.
- 50:42That's very good.
- 50:43Decision-based uh evidence-based data data production.
- 50:48Uh yeah.
- 50:49Well, yeah, it's interesting because uh one of my sisters worked in a government department that I can't name, but uh she was asked to go and find some data so to support what the minister had said.
- 51:00She went away and she came back and said, Well, there's no data to support it.
- 51:04They said, look harder.
- 51:06Yeah.
- 51:07So you sort of wonder, I mean, how much of this is just driven by political objectives.
- 51:12And especially when the one of the scientists who actually said it if a point six degree step occurs, it's it's not natural, it's an artifact.
- 51:21And then they brush off a one degree step.
- 51:25I mean, it's incredible.
- 51:28I kind of wonder too.
- 51:29Well, I want to ask you real quick.
- 51:31Just you know, this is very brave of you to publish a report like this December 23rd when you can have professional pushback from peers, threats from act activists.
- 51:42How has it been for you so far?
- 51:45Well, you know, that's this is why we formed correlation research in the public interest.
- 51:49Um, we are entirely independent, no funds from governments or corporations, just individual donations.
- 51:57Um you can see if you look at as soon as you look at the research section of our website and you see that all the reports that we've done.
- 52:06Um, I think any reader will see right away that we are independent, and we're willing to make analyses that establishment scientists won't do, essentially.
- 52:20They they won't they they they can't do it.
- 52:22Uh their their careers will be at risk if they do.
- 52:25And and so we're the we're one of the places in society where that can happen.
- 52:30And um we um we enjoy that we have that uh that freedom.
- 52:37And uh that's really important to uh to have uh I think uh um organizations uh doing that kind of work.
- 52:46Yeah, for sure.
- 52:46Because the government's not going to do it.
- 52:48Um that's very clear.
- 52:50Yeah, they're not well when one government employee finds mistakes in another government's work, they're not or another part of the government that they're not gonna go and tell the press.
- 53:00Yeah.
- 53:02Right.
- 53:02And and um they um might make some adjustments for I'm looking for the word um that was in uh environment Canada's response to the other Bank of Canada employee.
- 53:16Irregularities.
- 53:17When you're when there are irregularities, in other words, it's something that like the minimum temperature being greater than the maximum, it's it's just unbearable.
- 53:25You can't you have there has to have they have to do something about that, then they will address it.
- 53:32But um in other cases, like the case that I I uh put to Environment Canada, but the one degree stepping wise increase, they just brush you off, even if you are working within at another government institution.
- 53:48Uh yeah, that's what this report shows.
- 53:50You know, it kind of begs the question if a country as advanced as Canada, you know, who's supposedly part of the developed world, if we can make this mistake, isn't it possible that many countries, especially developing countries have similar big problems with their temperature data?
- 54:07Yes, uh climate and climatologists acknowledge that any station is gonna have big um discontinuities or or big uh uh moments, points at time in the data where um something unnatural happens, artificial or non-climatic, like uh stepwise increase or decrease or so on.
- 54:25But one thing I want to say in in in response to that question is that Canada being very organized and having a sense an army of scientists working for the government doing this kind of work, would be the kind of place that could quite quickly make a big broad change, like upgrade the or change the um technology at many stations in a short period of time.
- 54:54And so perhaps conversely, in a country like Canada, you could have this very broad widespread discontinuity affecting many stations at the same point in time or within the span of a year or so.
- 55:08Whereas that might be more difficult to accomplish in another country.
- 55:11So you might not see the same kind of glaring uh abrupt change uh in the temperature records in another country.
- 55:20That's yeah.
- 55:21Well, thank goodness, thank goodness you found it, because uh that work is so valuable.
- 55:26And how can people donate to the correlation research in the public interest group because you're doing super important work?
- 55:34Yeah, well, thank you for that.
- 55:35And and uh absolutely uh you can donate on our website, there's a donate section.
- 55:40Uh we also do our newsletter through Substack.
