The IPCC Says No Climate Crisis

Guest Post By Willis Eschenbach

OK, quick question: What do these weather phenomena have in common?

  • Air Pollution Weather (temperature inversions)
  • Aridity
  • Avalanche (snow)
  • Average rain
  • Average Wind Speed
  • Coastal Flood
  • Drought Affecting Crops (agricultural drought)
  • Drought From Lack Of Rain (hydrological drought)
  • Erosion of Coastlines
  • Fire Weather (hot and windy)
  • Flooding From Heavy Rain (pluvial floods)
  • Frost
  • Hail
  • Heavy Rain
  • Heavy Snowfall and Ice Storms
  • Landslides
  • Marine Heatwaves
  • Ocean Alkalinity
  • Radiation at the Earth’s Surface
  • River/Lake Floods
  • Sand and Dust Storms
  • Sea Level
  • Severe Wind Storms
  • Snow, Glacier, and Ice Sheets
  • Tropical Cyclones

Give up? So would I.

What these phenomena have in common is that the IPCC says that there is no significant evidence that these phenomena have changed (either increased or decreased) in the “historical period”. In other words, there’s no evidence that “global warming” has changed the strength or frequency of those weather phenomena.

So when folks claim things like “We’re already seeing the effects of global warming in storms/cyclones/floods/fire weather/sea level/etc./etc.”, feel free to tell them that the IPCC and reality itself beg to disagree.

And when Yale360 reflects on the 2017 Hurricane Harvey by saying ” If not for climate change, 2017’s Hurricane Harvey might have flooded half as many homes in the Houston area, a new study finds.” and “Climate change is happening right now with real and substantial costs”, you can feel free to point and laugh.

Don’t believe me? Here, with a large hat tip to a Substack post by Dr. Roger Pielke Jr., is Table 12.12 regarding “Climate Impact Drivers (CIDs)” from Chapter 12 of Working Group 1 of the IPCC Sixth Assessment Report, the most recent report:

Figure 1. IPCC AR6 WGI Chapter 12 Table 12.12

So … what weather phenomena does the IPCC say have actually changed? Well, they say global average air and ocean temperatures have increased by a few tenths of one percent. No news there.

Then they say “extreme heat” has increased. But they’re not talking about actual temperature. Instead, they’re using something called “Health Heat Index (HHI)”.

And while Table 12.12 in Chapter 12 says days with “extreme heat” increased in the historical period, the IPCC is disagreeing with itself. The problem is the previous chapter—Box 11.2 of Table 1 in IPCC AR6 WGI Chapter 11 says the increase in extreme heat is “Not assessed”, because the “baseline is 1981–2000”.

Sounds like dissension in the ranks …

Bemused by this “extreme heat” idea which the IPCC has both claimed and denied, I went to see how they calculate the HHI. Strap in and keep your arms and hands inside the vehicle, it’s a rough ride. Here are the calculations. The basic equation is:

HHI = c1 + c2 * T + c3 * T ^ 2 + RH * (c4 + c5 * T + c6 * T ^ 2) + RH ^ 2 * (c7 + c8 * T + c9 * T ^ 2))

T” is the temperature in °F, and “RH” is the relative humidity in percent. As for the others:

  • c1 = −42.379
  • c2 = 2.04901523
  • c3 = −6.83783 × 10−3
  • c4 = 10.14333127
  • c5 = −0.22475541
  • c6 = 1.22874 × 10−3
  • c7 = −0.05481717
  • c8 = 8.5282 × 10−4
  • c9 = −1.99 × 10−6

Zowie! Gotta love tunable parameters specified to 8 significant decimals. But wait, because as they say on TV, “There’s more!” Here are the further details.

If RH > 13% and T is between 80 °F and 112 °F, then HHI is adjusted by subtracting the following value:

Adjustment = ((13 – RH) / 4) * sqrt((17 – abs(T – 95)) / 17)

If RH > 85% and T is between 80 °F and 87 °F, the following value is added to HHI:

Adjustment =  ((RH – 85) / 10) * ((87 – T) / 5)

If HHI < 80 °F, then HHI is recalculated as follows:

HHI = 0.5 * (T + 61.0 + ((T-68.0)*1.2) + (RH*0.094)))

In order to confuse the unwary, the result is given units of degrees Fahrenheit (°F). However, this is not physically possible, because the calculation includes T, T^2, and sqrt(T).

In any case, “Extreme Heat” in the IPCC lexicon is when the Health Heat Index goes over 105°F, referred to as “AT105F” … whatever that means.

To find out how unusual the AT105F threshold is, I gathered the NOAA daily temperature and humidity data for 1582 US cities, and calculated the HHI for a number of them. Turns out that in some cities in the US, like say Yuma, Arizona, annually on average there are 30 days or more with an HHI of 105°F or more. Sometimes far more. This is supposed to scare us?

What else does the IPCC say has changed in the “historical period”? Well, they say “cold spells” have decreased. And I might be missing it, but I can’t find anywhere that the IPCC defines exactly what they are calling a “cold spell”. The IPCC Working Group I Glossary doesn’t define the term at all … so we have no clue what they’re referring to. Science at its finest. In any case, whatever they might think “cold spells” are, they say they’ve decreased in Australia, Africa, and Northern South America. Since cold spells kill far, far more people than heat spells, seems to me this is a good thing.

Other than that? Well, they say that river, lake, and Arctic sea ice have decreased.

And they have “Medium Confidence” that permafrost has decreased, that there’s been a slight decrease in dissolved oxygen and a slight increase in salinity in some parts of the ocean.

Oh, and surface CO2 levels have increased.

And that’s it.

Call me crazy, but I’m not seeing any “climate emergency” or “climate crisis” visible in any of that.

Of course, they go on to use the most alarmist, most useless future scenario, the scenario called either “RCP8.5” or “SSP5-8.5”, to make all kinds of claims based on Tinkertoy™ climate models about how bad things will be in 2050 and 2100 … but we’ve seen how totally wrong all such climate projections have proven to be over the last 40 years. So there’s no reason to believe these projections.

To illustrate some of these issues, I took a look at the US National Ocean and Atmospheric Administration (NOAA) extreme temperature and other extreme weather records for the US states. To start with, here are the decades when states hit their maximum temperatures.

Figure 2. State maximum temperature records by decade.

Now, bear in mind that the temperature has been rising, in fits and starts, over the entire period shown in these state extreme graphs. And more than half the states set maximum temperature records in the 1930s. Sorry, but given that data, I’m not believing that extreme temperatures are a problem in the US.

How about extreme minimum temperatures?

Figure 3. State minimum temperature records by decade.

No clear pattern in that one, which I suppose is why they specifically do not say there’s been a change in “cold spells” in the US.

Next, here’re the heavy 24-hour rain records:

Figure 4. State 24-hour rainfall records by decade.

Again, no clear pattern. Heavy rain peaked in the ’90s but has been decreasing since then.

Finally, here’s snowfall.

Figure 5. State 24-hour snowfall records by decade.

The period 1960-2000 was a time of heavy snow, but since then it’s dropped off.

This US data is just another part of the mountain of evidence as to why, despite all of the posturing, the IPCC doesn’t think there’s any significant evidence of any “climate emergency” or “climate crisis”.

However, don’t expect things to change soon. We now have what might be called the “Climate/Industrial Complex”, complete with lots of people making lots of money off the imaginary “climate crisis”, and as Upton Sinclair remarked,

It is difficult to get a man to understand something, when his salary depends upon his not understanding it.

I’ve covered this lack of any evidence for a climate “crisis” or “emergency” in my post “Where Is The Climate Emergency?“.

And the alarmists’ answer to that question?

“We doan gotta show you no steenkin’ emergency … we’re climate scientists!”

Yeah, right …

Actually those weather phenomenon do have a couple of things in common.
1) They are ALL part of Normal Weather
2) They happened in…



…1700s (in fact the worst hurricane on record was in 1780 killing 24,000 then another in 1782 killing 3,500)
Probably similar weather issues in 3 digit years as well as years BCE

I have found that the case for just about any science publications supporting climate change. The IPCC are even worse because the actual scientists involved have no input on summaries.

After reading the final summary, you think where did they get that from because it wasn’t in the paper.

Reply to  Matt G
July 31, 2023 12:21 am

As I unerstand the IPCC process, the Summary for Policy Makers is written first (as the I stands for Intergovernmental) and the role of the scientists is to then find some suppporting evidence to go in the reports.

Of course, there is no guarantee that supporting evidence can be found in the real world.
But, as the table shows using RCP8.5, that’s what models are for.

“Science” requires a falsifiable hypothesis.

If your rocket blows up on the launch pad, EVERY time, then even the peasants are going to opine that you are doing something wrong and perhaps don’t quite understand rocket science.

When you make vague climate predictions that are mostly wrong, but lack the video equivalent of an exploding rocket, then apparently you can have job security for life at NASA regardless of whether you actually know anything about climate science.

Large hat or large tip?

Gotta love tunable parameters specified to 8 significant decimals

That’s how you make the elephant’s ears wiggle.

I’m entertained by recent spate of claims, in C or F, that humidity/temp index over 105°/40° causes human body systems to shut down and slow death. In many temperate zone cutures around the world people enjoy sauna at artificially maintained levels much higher, and mostly claim health and well being benefits for the experience. An aquaintance pays to participate in hot yoga sessions at near those conditions multiple times a week (yet none the less becomes quite dramatically plus le verklempt on command at every such announcement).
Most often, outdoor temps + humidity at near those levels cause rain, and as you’ve noted elsewhere (and experrienced hear near Yuma in the “monsoon” season), can reduce the temperature by 30 or more F degrees.

Stay cool!

As Willis pointed out, the result of the equation is a mix of units of different powers. One could use the principles of error propagation to come up with a number representing the uncertainty in HHI units. However, it gets a little trickier with the IF…THEN steps specified. But then the IPCC has never paid much attention to rigorous analysis of error, so this is nothing new. It makes it convenient to pretend that the HHI numbers are exact.

with four parameters I can fit an elephant, and with five I can make him wiggle his trunk”

Attributed to John von Neumann by Enrico Fermi, when he was asked about the value of a result that used four free parameters in fitting experimental results.

Not trying to one-up Fermi or Von Neumann, but if you’re gonna cook the books, why not shoot for overdone? IPCC is overcomplicating a relatively simple job, already accomplished much better elsewhere, to come to a ludicris result and a ridiculous claim. Forget my expansion to the elephant’s ears — that’s a row of pink pachyderms, dancing.

I understand therefore that the IPCC report proper and the Executive Summary poles apart; one is more based on “evidence”, the other is wholly narrative driven unreality prepared for gaslighting politicians and their WAG/CC Oughtist apparatchiks (sorry lying bastards) to push their Woke blx.

Yes, I remember reading the IPCC’s processes a while ago (AR6?), and the docs on the IPCC website described how the agreed draft statements in the SPM were sent back to the lead authors of the scientific reports sections with directives to amend the scientific positions to agree with the draft SPM statements.

It is difficult to get a man to understand something, when his salary depends upon his not understanding it”.

In 2009, Daniele Fanelli conducted a survey demonstrating that at least 72 percent of researchers were willing to somehow distort their research results. And that doesn’t even count the unintentional calculation mistakes and other errors.

Lets look at the timeline after James Hansen in 1988, (A)GW was as a soft word presented in the First Global Revolution, published by The Club of Rome in 1991, in 1995 it became AGW, then Climate Changes and Climate Crisis … and now ´Global Boiling´. Using soft language, 32(35) years has gone and it´s “hard” not to conclude that the traveling “pathogens” in the evolvement in the alarmistic rhetoric causes “global boiling” blindness.

Weather-stations excist in the categories from 1 to 5. In the best case scenario, you can say, that the IPCC-reports is a class 3 weather station. The Resume to the politicians and the medias, belongs in class 5, not trustworthy at all.

But unfortunatly the “hockey-stick” phenomenon going from a soft word GW to global boiling, your out of order, trust the science, creates mass-formation. In psychology and neurology you would say that the gaslighting is the result of the allegory of the frase “The Sky is Falling” – and so is the tendency to turn the “blind” eye to what your presenting isn´t even close to being class 1 science …!!

We may find out where Joe Biden’s off-shore bank account is tomorrow, after Hunter Biden’s former business partner testifies before Congress

Devon Archer is his name. He has been in hiding recently after receivig death threats, and threats from the Biden “Justice” Department.

I think the Biden family may hold the record for the most “Suspicious Activity Reports” filed on one family. There are about 170 SAR’s on the Bidens, and another 70 or so on people connected to the Bidens.

Banks file SAR’s with the U.S. Treasury Department whenever they think they are seeing illegal banking activity. Apparently the banks had a lot of suspicions about a lot of Biden financial activites.

I think ole Joe isn’t as smart as he thinks he is.

I am so curious about this and like you will be keen to see if this goes anywhere. But do you have any credible references for Devon Archer is his name. He has been in hiding recently after receivig death threats, and threats from the Biden “Justice” Department.”

So let’s for a second imagine J Biden is guilty of a crime. Do you think he should be held accountable, or do you think he should be able to use his power as president to veto any conviction? I only ask because this could play out with a future president with the initials DT and in the interest of being fair and consistent I’m assuming you will want both men treated the same? For the record I am very keen for Biden to be convicted and face the consequences if guilty, as I am if Donald gets done for any of his current charges.

The only reference I have is I heard this said by a reporter on the Fox News Channel, and I’m just repeating it. I don’t know where the reporter got their information.

I do think Joe Biden should be held accountable if he is guilty of a crime. The method to be determined considering his age and health. Although, I might be a lot harsher, if we find out Biden was doing the Chicoms favors for money. That would make Biden a traitor to his country, and that cannot be treated lightly.

I don’t think Biden can veto any personal conviction. An impeachment and removal from office is not subject to a presidential veto, nor are any criminal matters he is involved in. He won’t be convicted of anything before he leaves office, so he won’t be able to pardon himself.

Donald Trump if elected president, could pardon himself, if he were found guilty of a crime during the election but went ahead and won the presidency anyway. He could pardon Biden, too, if he decided to do so.

But I don’t think in Trump’s cases that they will ever see a jury. The cases are such bad law they will be thrown out of court before ever going to trial.

Of course, there are a lot of Obama and Biden appointed judges out there so nothing is certain at this point, but my money is on Trump, Truth, Justice, and the American Way!

Firstly thank for your reply. You are right re impeachment if that is where this goes with Biden. He wont get out of that, but to be impeached he will have to be guilty and we are a long way from that. I will watch the result of the mans testimony although I hear it is behind closed doors.
Re Trump. I am not so sure the cases are as flimsy as you say given there are recordings and emails that are pretty damning. And the judge in the documents case is a Trump appointee. She has set a date and it lands right in the middle of the Republican primaries. I appreciate he may well win that so it is going to be very interesting to watch.

“but to be impeached he will have to be guilty”

No, that’s not true, Simon. Trump was impeached twice and he wasn’t guilty of anything either time.

Mark Levine laid out a few problems for the prosecution with regard to Trump and the classified documents case. First of all, federal cases are supposed to be charged in the district where the crime supposedly was committed. That would be in Florida, not in Washington DC.

They are trying to charge Trump under the Espionage Act of 1917, which does not apply to this case.

The Presidential Records Act covers all Trump’s activities, and he has complied fully with the Presidential Records Act, which is not a criminal matter, even if he were guilty of something. That’s why they put the Espionage Act charge in there.

The case ought to be thrown out of court over the jurisdiction issue alone.

Those future court dates are flexible, and either probably won’t go to court at all, or will be extended until after the elections of 2024.

It will be interesting to watch. 🙂

“First of all, federal cases are supposed to be charged in the district where the crime supposedly was committed. That would be in Florida, not in Washington DC.”
He is being charged in Florida, by his judge????

“They are trying to charge Trump under the Espionage Act of 1917”
I think you will find this clause in the act is the one that is going to be trouble for him
“it is a crime to have “unauthorized possession of, access to, or control over [information] … the possessor has reason to believe could be used to the injury of the United States or to the advantage of any foreign nation,” and to “wilfully” retain it while failing “to deliver it to the officer or employee of the United States entitled to receive it.”
Under the law, prosecutors will not be required to prove that Mr Trump knew that the information he possessed could harm national security interests, but rather that any reasonable person would understand the harm it could do. It also is not necessary under the law to prove that the documents were classified – only that they relate to US national security – or that they caused any actual damage to US interests.

And you didn’t answer my question. If Trump is found guilty by a jury, overseen by a judge he chose and in the state of Florida, should he be able to exonerate himself?

Tom Abbott
Reply to  Simon
August 1, 2023 3:56 am

Trump, under the Presidential Records Act, was authorized to have every document he had.

The prosecutor claims Trump showed a classified document to someone who wasn’t authorized to see it. Trump emphatically denies there even was a document to show during this particular conversation he had with others. This should be easy to prove. I’ll put my faith in Trump. You don’t have to.

“And you didn’t answer my question. If Trump is found guilty by a jury, overseen by a judge he chose and in the state of Florida, should he be able to exonerate himself?”

I don’t think he should exxonerate himself if he is guilty of something, but I don’t see he is guilty of anything. All the charges against him, ALL of them, are trumped up and imo, will not hold up in court.

The radical Democrats have a coordinated effort, federal and local, to dirty up Trump before the election, and their method is to charge him with everything in the book.It doesn’t matter if the charges are legitimate, all that matters is the appearance of criminality.

The radical Democrats are creating a false narrative in hopes of keeping Trump out of the White House. Because they are scared to death Trump is going to destroy their socialist dreams, and they are correct, Trump will destroy their socialist dreams if he gets back in office.

So the gloves are off for the radical Democrats. They are going to do everything they can, legal and illegal, to get Trump. They’ve been trying to do this for five years now, and haven’t gotten him yet. I don’t expect they will get him this time, either.

Simon, the source for the information on death threats to Devon Archer is Maranda Devine, the New York Post reporter that broke the Hunter Biden laptop story.

The story that was suppressed by the Deep State right before the 2020 election. Polls taken after the election showed that from10 to 20 percent of people who voted for Biden would not have voted for him had they known about the laptop scandal, so the suppression cost Trump the election. That, among other things.

So Tom it seems this guy Devon Archer said Biden often joined conversations but it was always chit chat and never specific business. There is no doubt Hunter wanted to create an illusion that he had connections, but that is about it. Nothing about bank accounts or business dealings….. and if chatting with your parents or using them to promote yourself is a crime, then I’m guessing nearly all of Washington will need to resign… certainly the Trumps.

No, Simon. We don’t actually know what Devon Archer said since the hearing was done behind closed doors.

What you are repeating is the Democrat talking point they used after the hearing. “Nothing to see here” say the Democrats. Well, wouldn’t you expect they would say that? I would. What else can they say?

Ole Joe has been caught dead to rights, using his influence with foreign entities.

What’s really going to be interesting is tracing the amounts of money Hunter and Joe got from the Chicoms, and then looking at what policy changes occurred with regard to China after the money was sent.

Back in 2014, Joe signed off on allowing Chinese companies to trade on the U.S. stock exchanges, while allowing the Chinese companies to ignore the rules set for other companies that trade on the U.S. Stock Exchange. This is still in effect to this very day. I wonder how much money the Chicoms paid Biden for that little favor?

Exactly, yesterday there was some congressional clown (D) going around and claiming they were “only talking about the weather.” Yeah right, how would he know? Was he part of the conference calls? Of course not, he was saying what the White House told him to say. And of course, Simon jumps on and claims it was only “chit-chat”. How would Simon know what was discussed?

After the Archer transcripts are released in a couple days, there won’t be any more ridiculous democrats following suit.

Devon Archer testified before the House Oversight Committee behind closed doors on Monday. The interview and bombastic revelations against the Biden Crime Family were mostly ignored by the compromised mainstream media.

Devon Archer is Hunter Biden’s best friend and business associate of many years. Archer testified that the Joe Biden was included on 20 calls when his son was sitting with foreign officials arranging influence peddling deals for the family.

Archer also testified that Joe Biden met with Russia’s Yelena Baturina who invested $40 million into Hunter Biden’s real estate ventures. And she also paid Hunter Biden $3.5 million in consulting fees. Joe Biden later excluded Baturina from his Russian sanctions list.

During the interview Devon Archer told Tucker Carlson that Joe Biden KNEW Hunter’s foreign business partners were in the room during their phone calls!

I always use Kelvin as the basis for calculations. We did sometimes use Rankin when in college, but Kelvin is the preferred. It does make a difference in the final numbers, albeit sometimes small when calculating anomalies. The real benefit is that using a system based on absolute zero eliminates negative numbers.

Along the same line of thought (stability, percent temperature), would not the fourth power relationship in the Stefan-Boltzmann equation suggest natural self-regulation vs “tipping point” scenario?

A 1.5% increase in temperature (4.5/288K) produces 5% increase in emission. Like the logarithmic function of Beer-lambert absorption, but for emission. Both non-linear, both indicate diminishing returns.

Actually, one of the ‘rules’ of maths is that you don’t round intermediate numbers. eg. “Do not round your results until the very end or you will introduce errors that may grow in coming steps.” – Sage-Advices. Normally, intermediate numbers don’t get reported. In this case, they probably did have to be reported, as they are the numbers provided for use in later steps.

Fun true story as an exception. In college I took Galbraith’s course on artificial demand creation (think advertising) based on one of his books. He loved telling non-course stuff on the side that made you think.

During WW2 he headed the Office of Price Administration. He told us that he learned to sum long columns of numbers in his head quickly to within 10%. The trick was only going to maybe first two digits and ignoring the rest, since it was likely those mostly cancel.

Then he got to the point of the lesson. “In economics, if an answer to within 10% isn’t good enough, then you are asking the wrong question.”

“Maths” is not a word in English. “Math” is the abbreviated form of “mathematics”, so “maths” is redundant plural – “mathematicss”.

Rounding is not appropriate in conducting mathematical calculations, only for qualifying the final answer.

The proper means of calculation is to use the rule of significant figures. No mathematical equation’s output is more precise than the fewest number of significant figures in the operands, with the smallest non-zero number as directly measured + 1 (for estimating the value between 2 measured quantities).

A measured value of 10 is 3 significant figures (2 + an estimate, not measured, of the 3rd figure). An answer involving a number with 2 significant figures and a number with 3 significant figures is precise to only 2 significant figures.

Does a measured value 10.0 have four significant figures?

Reply to  Curious George

Writing 10.0mm as a measured value, implies that you could measure to the 1st decimal place. Hence 3 significant figures.
Just like if you measured it as say 10.2mm

If you can measure to the nearest 1/100th of a mm, then you could write 10.00mm… which is 4 significant figures.

ie the trailing zeros are what is referred to as “implied accuracy.”

However, if you start with only one or two significant figures, one is probably only required to carry an extra guard digit in the intermediate calculations. Then, at the end, round down to the number of significant figures in the least precise multiplier.

I am happy that Willis is reporting on Roger Pielke, Jr. His blog is a rich source of interesting material that analyzes and refutes much nonsense coming out of the climate change establishment. I think everyone who reads WWUT could subscribe to it and read it with profit. Although, be warned, Roger accepts the idea that the atmosphere is getting warmer.

Here is an excerpt from an important recent post by Roger about the radical political agenda of the IPCC:

“The Political Agenda of the IPCC Scientific Assessment or Environmental Advocacy Group? Pick One” Roger Pielke Jr. on May 15, 2023

So what is the political agenda of the IPCC in-group? Transformational change. When the IPCC released its Synthesis Report in March, it announced: ‘… change everything from public policies and prevailing technologies to individual lifestyles, and social norms to governance arrangements and institutions of political economy Transformational change means that everything changes.’

* * *

The IPCC – or to be more precise, influential elements of the IPCC – appears to have been captured by an in-group with shared political views related to climate. These views embrace concepts like degrowth and planetary boundaries and turn climate policy on its head such that ends become means. Transformational change views climate policy as a lever through which to “change everything.” The expressed need for such momentous changes across society are grounded in a frightening, even apocalyptic, perspective on the future.

* * *

… The IPCC has clearly departed from its role as a scientific assessment and is now much more deeply engaged in political advocacy. Trying to simultaneously engage in assessment and advocacy is never a good idea. I hypothesize that the IPCC’s political agenda of transformational change plays more than a small role in its stubborn reliance on implausibly extreme scenarios and its multiple errors and omissions related to the science of extreme weather and disasters — both of which help to underscore the demand for urgent and large-scale societal change. …

He is probably right because there is evidence that the growing seasons are getting longer, if nothing else because the average time of the last killing frost is getting earlier and the time of the first killing frost is getting later.

For many years now, the IPCC has touted “confidence intervals” in their assessment reports:
“A level of confidence is expressed using five qualifiers: very low, low, medium, high and very high, and typeset in italics, for example, medium confidence. The following terms have been used to indicate the assessed likelihood of an outcome or result: virtually certain 99–100%
probability; very likely 90–100%; likely 66–100%; about as likely as not 33–66%; unlikely 0–33%; very unlikely 0–10%; and exceptionally unlikely 0–1%. Additional terms
(extremely likely 95–100%; more likely than not >50–100%; and extremely unlikely 0–5%) are also used when appropriate.”
(see footnote 4 at bottom of page 4)

Such non-deterministic “evaluations” lend credibility where none is actually warranted, and thus have caused many a keen observer to conclude IPCC assessment reports have been nothing but a confidence game from the get-go.

Extreme anything only makes sense when qualified by date and location and elevation or altitude. It is never an absolute value. Extreme heat at the North Pole in January might be 0 deg C. But that would be considered extreme cold in Los Angeles in July. What passes for extreme heat in Phoenix in July (115 + deg F or more) simply does not occur ever in Aspen. It’s all relative, and literally everybody knows that.

For those who say extreme anything is really about the biological effects, such as a person suffering heat stroke, it’s still prejudicial to label anything as extreme. Heat stroke is brought on by the body’s cooling system no longer functioning, not because of the absolute air temperature. The failure to cool the body is usually triggered by dehydration – and a body can be dehydrated at any air temperature. Being in direct sunlight vs shade also makes a humongous difference (there we skeptics go again, blaming it on the pesky old sun instead of the obvious villain, CO2). Clothing makes a difference too.

A body can suffer hypothermia at an air temp of 70 deg F – if their body is wetted and a strong wind is blowing and they are wearing few clothes.

Labeling any weather condition as “extreme” is simply hyperbole and hysterical. Weather just is. The media could talk about data relative to mean values, or as probabilities (a 100 year storm). But they seem to prefer scaring people because it draws mouse clicks and ratings points. Today’s version of the old newsman’s saying, “If it bleeds, it leads”.

“For 12 consecutive days, from Sunday the 16th to Thursday the 27th, the capital of the country experienced sub-zero temperatures. A persistent high-pressure system and intense masses of cold air resulted in clear skies, cold air, and calm winds during the dawn. And the result was this historic sequence of cold mornings.

Over the past 30 years, Canberra has only had four streaks of subzero temperatures lasting longer than 10 days (in any month or combination of months). The longest streak was 14 days in both 1994 and 2002.

Lots of posts and comments here over recent days have been dismissing the surface data record warmth. Let’s see what UAH have say; because UAH is the favoured data set on this site.

I think they will report a warmest or near-warmest July. TLT data differ a bit from surface data in the early art of El Nino; as I recall, they take longer to respond but respond more strongly when they do. So there are a lot of very high UAH temperatures to come over the next few months.

You have just hit a pet peeve of mine. Anomalies are NOT temperatures and can not be compared in the fashion you are doing. An anomaly is ΔT, and not an absolute value. A temperature station in the Antarctic can have an anomaly of +2, and be similar to an anomaly in Houston, Texas, yet the absolute temps are totally different.

Your use of anomalies as a measure of how hot it is leads to the media and many scientific studies doing the same. That is why we see every location on the globe warming at an unprecedented rate according to the media. At best, the anomaly you are quoting is an average. Guess what an average actually is? It is the value in the middle. That means half the anomalies are above the average, and half are below. That immediately says that the entire globe is not warming at an unprecedented rate.

Here is the proof of the filling in the pie. Willis has tried to show you that state temperature records are not falling left and right. What do you make of that? Is the U.S. hotter now than it has ever been? If so, why aren’t there 48 state records being set every year?

We are only in a period of high global temperature during the Holocene and have not reached the Holocene Climate Optimum (HCO) yet.

There are good reasons for dismissing the surface record because it is generally poor and highly affected by UHI’s. It has been changed often to support the warming narrative and has huge areas of missing observations especially before the satellite era and argo.

The UAH is the best global temperature monitoring instrument on the planet.

The satellite is warming more than the surface during the El Nino so far.

The reason why they likely will be a July record and not an overall record is because the El Nino is predicted to become medium strength. Only a strong El Nino has the chance of beating a previous high in satellite data despite high North Atlantic SST’s.

Like most alarmists you are so mealy mouthed.

So what should the Earth’s temperature be then? Hotter, colder, the same, what?

We know that the ‘change’ in temperature is measured basically from the end of the Little Ice Age. So would Mankind be better off if temperatures were the same as the LIA? Or would it be better off if it was colder or hotter than those temperatures, what? Be specific and give reasons.

We do think that Man has altered the Earth’s temperature somewhat. Why do people assume that this is harmful? What are the odds between this being beneficial or harmful? If Man could prevent the next glacial period, should we?

So speak up, say what YOU think.

Not sure I understand the point of your comment. Presumably you are trying to support Willis’s view?
Willis said that throughout the historical period the temperature has been rising slightly but there is no climate emergency and that the IPCC’s own data support that view. You predict that in a few days UAH data may show a slight rise in temperature, which is in agreement with Willis’s statement. It will not under any circumstances show that we are in a climate emergency or that the IPCC is wrong in its assessment that the indices cited are not increasing. So if your prediction comes true it will support Willis’s article.
That is what you intended, right?

Your Figure 3 State minimum temperature records by decade – appears to show [again, by eye] about 50 states.; so does your Figure 4. State 24-hour rainfall records by decade.

I guessed – but no more – that the first, Figure 2, includes cumulative records, so if [say] Nebraska had a record of 103F in 1935, and then reached 107F in 1993, both are counted.
But looking to the source data for tmax, at it looks as if there are just 50 states.

But wait! If only the HHI equation was that simple!

A description of the equation shown above may be found in the NOAA techincal attachment SR 90-23. This reveals that in reality, it is only a curve fit to a much more complicated model, described in two papers, “The Assesment of Sultriness” Parts, I and II (all linked below).

What we find is that this is all based on the average human, wearing averge clothes, and is incredibly complex. How many average humans do you know?

You beat me to this. This is a curve fitting process and NOT a functional relationship describing the mathematical relationship between variables.

Let’s do a little dimensional analysis for the “c” values.

First let’s rewrite the equation using PEMDAS rules.

HHI = c1 + (c2 • T) + (c3 • T²)) + RH[c4 + (c5 • T) + (c6 • T²)] + RH²[c7 + (c8 • T) + (c9 • T²)]

c1 => ° F
c2 -> unitless constant
c3 => ° F⁻¹
c4 => ° F
c5 => unitless constant
c6 => ° F⁻¹
c7 => ° F
c8 => unitless constant
c9 => ° F⁻¹

I would sure like to see the science behind these values. I rather suspect they were developed by a software curve fitting package or by trial and error to get the value they wanted.

Reply to  Jim Gorman
July 31, 2023 2:35 pm

This HHI result is almost certainly the output of a general linear regression utility inside a standard package; GLR regresses data to an equation given by the user and spits out the constants for the best fit, with 6-8 digits typical (GLR is usually the insides of the polynomial fit routines). There is nothing at all analytical about the process, just guessing about what an appropriate equation to describe the data might be. That they ended up with “adjustments” for different input ranges tell me their guesses were poor.

I’m struggling to remember high school chemistry, but if I remember rightly a single molecule of H2O and one of CO2 will not easily bond, but liquid water bonds with CO2 on contact, hence every drop of rain that has ever fallen on this planet is a mild solution of carbonic acid. I don’t think single molecules of H2CO3 will be found floating in the atmosphere though.

Reply to  Right-Handed Shark

H2CO3 is almost impossible to be found in water as well, it’s an extremely short-lived intermediate en route to HCO3^- and CO3^–.
When carbon dioxide dissolves in water about one-percent of it forms carbonic acid, which almost immediately dissociates to bicarbonate anions and protons. Despite its fleeting existence – about 300 nanoseconds – carbonic acid is a crucial intermediate species in the equilibrium between carbon dioxide, water.”

I have previously written why I think that using the term ‘acidification’ with respect to a claimed lowering of pH in the oceans is a bad idea. The IPCC Table 12.12, Figure 1, illustrates an additional reason.

The claim has been made that the open oceans have declined from a pH of 8.2 (derived from a model, not measurements), to the present day value of 8.1. However, Table 12.12 shows no entry for “Ocean Acidity” in the Historical Period column. There are entries for the other two columns of “High Confidence” of an increase in acidity.

One might be forgiven for concluding that because it is commonly accepted that the pH has lowered in recent time, but there is no entry for Historical Period, that what is meant is that we can expect that the open ocean surface waters will actually become acidic and then become more acidic. No less than Stanford geochemist Konrad Krauskopf has stated that he thought it improbable that buffering will allow any but some deep, stagnant, bottom pools enriched with hydrogen sulfide would actually reach a pH below 7.

Therefore, the conflicting implications leads to ambiguity in the meaning of the table with respect to the future pH of the oceans. Scientific statements should be as precise as the author is capable of writing. By giving ‘spin’ with words with pejorative meaning, the authors have managed to make their writing less clear than it should be. It speaks to their priority.

Of course, they go on to use the most alarmist, most useless future scenario, the scenario called either “RCP8.5” or “SSP5-8.5”, 

Given that SSP5-8.5 is considered highly unlikely, and SSP2-4.5 is likely by the IPCC and Hausfather, Zeke; Peters, Glen P. (2020-01-29). “Emissions – the ‘business as usual’ story is misleading”. Nature. 577 (618–620). doi:10.1038/d41586-020-00177-3, why do they use it?

Reply to  Redge
July 31, 2023 4:23 am

Given that [ either “RCP8.5” or ] SSP5-8.5 is considered highly unlikely … why do they use it [ / them ] ?

Answers to this sort of question are provided in the WG-II (adaptation) and WG-III (mitigation) contributions to the AR6 document cycle.

“Why use them at all ?” is answered in WG-III’s “FAQ 3.3 : How plausible are high emissions scenarios, and how do they inform policy?”, on page 386 :

Hausfather and Peters (2020) pointed out that since 2011, the rapid development of renewable energy technologies and emerging climate policy have made it considerably less likely that emissions could end up as high as RCP8.5. This means that reaching emissions levels as high as RCP8.5 has become less likely. Still, high emissions cannot be ruled out for many reasons, including political factors and, for instance, higher than anticipated population and economic growth.

The IPCC has to be able to model the “undesirable” cases of too much wealth creation (for non-elites, obviously …) or too many ignorant peasants still being around in 2100, hence the extensive use of RCP8.5 (/ SSP5-8.5), however “counterfactual” the WG-I scientists declare them to be.

They are politically “useful” scenarios.

. . .

The answers to questions like “But what’s the underlying point ?” are more concentrated in the WG-II report.

In “FAQ1.5 : What is new in this 6th IPCC report on impacts, adaptation and vulnerability?”, on page 180 :

The AR6 emphases the emergent issue on social justice and different forms of knowledge. As climate change impacts and implemented responses increasingly occur, there is heightened awareness of the ways that climate responses interact with issues of justice and social progress. In this report, there is expanded attention to inequity in climate vulnerability and responses, the role of power and participation in processes of implementation, unequal and differential impacts, and climate justice. The historic focus on scientific literature has also been increasingly accompanied by attention to and incorporation of Indigenous knowledge, local knowledge, and associated scholars.

Forget your (/ our) “historic” focus on scientists publishing papers in “serious” journals, all we need to do now is listen to those “associated scholars” who tell the IPCC what they want to hear.

For AR6 both WG-II and WG-III shifted towards more “societal / political” objectives — as opposed to WG-I’s continued focus on “The Scientific Basis”, after you get past the SPM ! — as explicitly admitted in the third (of three) points made in section 1.1.4, “What is New in the History of Interdisciplinary Climate Change Assessment”, on page 131 of the WG-II assessment report :

Third, AR6 has a more extensive focus on the role of transformation in meeting societal goals (Section 1.5).

The reasons the IPCC uses RCP8.5 (and SSP5-8.5) are clearly stated in the WG-II and WG-III reports, you just have to dip into them to read exactly “where they are coming from” … though be warned that you will probably want to take several showers afterwards …

Editorial note : For some reason I missed the following extracts when compiling my previous post, even though they were definitely in my sub-conscious at the time.

Note also that after re-reading it I definitely entered “school-marm mode” somewhere along the line …

. . .

The IPCC also provide some “historical perspective” on the development of the RCP and SSP “emissions pathways” for use in AR5 (2013) and AR6 (2021) respectively.

In the WG-III (mitigation) report Box 3.3, “The likelihood of high-end emission scenarios” on page 317, actually provides a decent summary of how RCP8.5 was originally developed :

At the time the Representative Concentration Pathways (RCPs) were published, they included 3 scenarios that could represent emission developments in the absence of climate policy: RCP4.5, RCP6 and RCP8.5, described as, respectively, low, medium and high-end scenarios in the absence of strong climate policy (van Vuuren et al. 2011). RCP8.5 was described as representative of the top 5% scenarios in the literature. The SSPs-based set of scenarios covered the RCP forcing levels adding a new low scenario (at 1.9 W/m2). Hausfather and Peters (2020) pointed out that since 2011, the rapid development of renewable energy technologies and emerging climate policy have made it considerably less likely that emissions could end up as high as RCP8.5. Still, emission trends in developing countries track RCP8.5 Pedersen et al. (2020), and high land-use emissions could imply that emissions would continue to do so in the future, even at the global scale (Schwalm et al. 2020). Other factors resulting in high emissions include higher population or economic growth as included in the SSPs (see subsection 3.3.1) or rapid development of new energy services. Climate projections of RCP8.5 can also result from strong feedbacks of climate change on (natural) emission sources and high climate sensitivity (see WGI Chapter 7), and therefore their median climate impacts might also materialise while following a lower emission path (e.g., Hausfather and Betts (2020)). The discussion also relates to a more fundamental discussion on assigning likelihoods to scenarios, which is extremely difficult given the deep uncertainty and direct relationship with human choice. However, it would help to appreciate certain projections (e.g., Ho et al. (2019)). All-in-all, this means that high-end scenarios have become considerably less likely since AR5 but cannot be ruled out. It is important to realize that RCP8.5 and SSP5-8.5 do not represent a typical ‘business-as-usual’ projection but are only useful as high-end, high-risk scenarios. Reference emission scenarios (without additional climate policy) typically end up in C5-C7 categories included in this assessment.

NB : This is where my memory of RCP8.5 being “useful” to the IPCC in allowing the promotion of “high-end, high-risk” — AKA “dangerous” or “catastrophic” — scenarios came from.

. . .

In the WG-II (adaptation) report, sub-section “AR6 WGI Reference Periods, Climate Projections and Global Warming Levels” in “Cross-Chapter Box CLIMATE : Climate Reference Periods, Global Warming Levels, and Common Climate Dimensions”, on page 136, also has some “historical” background :

The plausibility of emissions levels as high as the emissions scenario conventionally associated with the RCP8.5 and SSP5–8.5 concentration pathways has been called into question since AR5, as has the emissions pathway feasibility of the low scenarios (Hausfather and Peters, 2020; Rose and and M. Scott, 2020). However, these views are contested (Schwalm et al., 2020, for RCP8.5), and it is important to realise that emissions scenarios and concentration pathways are not the same thing, and higher concentration pathways such as RCP8.5 could arise from lower emissions scenarios if carbon cycle feedbacks are stronger than assumed in the integrated assessment models (IAMs) used to create the standard scenarios (Booth et al., 2017). In the majority of full-complexity Earth System Models, these feedbacks are stronger than in the IAMs (Jones et al., 2013), so the RCP8.5 concentration pathway cannot be ruled out purely through consideration of the economic aspects of emissions scenarios. Nonetheless, the likelihood of a climate outcome, and the overall distribution of climate outcomes, are a function of the emissions scenario’s likelihood. Note that the original RCPs were created explicitly to facilitate a broad range of climate modelling experiments, with the expectation that other issues, such as socioeconomic uncertainty, could be subsequently explored (Moss et al., 2010).

. . .

Given that SSP5-8.5 is considered highly unlikely, and SSP2-4.5 is likely by the IPCC …

The IPCC actually used the term “counterfactual” rather than “highly unlikely”, and unfortunately you (/ we) have to infer RCP8.5 from what they wrote.

From the WG-I (The Scientific Basis) report, in section, “The likelihood of reference scenarios, scenario uncertainty and storylines”, on page 239 :

Among the five core scenarios used most in this report, SSP3-7.0 and SSP5-8.5 are explicit ‘no-climate-policy’ scenarios (Gidden et al., 2019; Cross-Chapter Box 1.4, Table 1), assuming a carbon price of zero. These future ‘baseline’ scenarios are hence counterfactuals

Studies that consider possible future emission trends in the absence of additional climate policies, such as the recent IEA 2020 World Energy Outlook ‘stated policy’ scenario (International Energy Agency, 2020), project approximately constant fossil and industrial CO2 emissions out to 2070, approximately in line with the medium RCP4.5, RCP6.0 and SSP2-4.5 scenarios (Hausfather and Peters, 2020b) and the 2030 global emission levels that are pledged as part of the Nationally Determined Contributions (NDCs) under the Paris Agreement …

In the “Higher GHG (/ CO2) emissions = Higher atmospheric CO2 levels = More Radiative Forcing (RF) = Higher GMST anomalies” chain of reasoning you will find that RCP8.5 is neatly bracketed by SSP3-7.0 and SSP5-8.5.

If SSP3-7.0 is above the IPCC’s “counterfactual” threshold then so is RCP8.5.

Attached is a graph I updated at the beginning of the year illustrating this, using “FF&I CO2 emissions” in this particular case.

Up to ~2014 emissions were following RCP8.5 — and remember that AR5 was published in 2013, using data up to 2011/2012 — but since then “we” have essentially been following RCP4.5 / SSP2-4.5 instead.

NB : Roger Pielke Jr. may have a point about SSP4-3.4 being the “most likely” emissions pathway in the medium term (up to 2050 / 2070).
SSP4 may well be politically more viable, with less “socioeconomic uncertainty”, than SSP1[-2.6].

I wonder what the original curve they are presumably trying to fit looked like, because the output of that equation is going to be chaotic! But I do know that is the description of weather, why don’t they just say that, in place of ridiculous meaningless random numbers? And then those modifiers because they don’t like the answers from their magic equation? They also believe in dicontinuous functions, oh no that is a definition of “tipping point”!

Hi Willis,

A while back I requested data to confirm your results. Here is the Chat GPT confirmation of the statement I made reference to:


Default (GPT-3.5)

In November 2009, thousands of emails and documents from the CRU were illegally hacked and leaked online. These emails included conversations between climate scientists, including Phil Jones, and the leak was highly publicized. Climate change skeptics seized on the contents of these emails to cast doubt on the integrity of the climate science community and their research.

In one of the leaked emails, Phil Jones responded to a data request from Stephen McIntyre with the following statement:

“Why should I make the data available to you when your aim is to try and find something wrong with it?”

Thanks. It is not important whether Jones wrote to McIntyre or Hughes. The issue is whether data used in an analysis is archived and made available for other researchers. WUWT should be the gold standard if it expects to convince the climate community.

A link to primary data is not sufficient for anyone who is not a paid climate researcher. Reanalysis of derived data is typically orders of magnitude faster at getting value for time spent, especially when methods are in dispute.

For example, the Holder Inequality restricts the use of the S-B Law to derive average temperature from average radiation. Holder says the solution is not unique, so a reanalysis of the derived data is a likely place to check the math.

Requesting derived data I was reminded of the quote I thought Jones had written in the distant past. I likely associated it with McIntyre because of ClimateGate. Chat GPT has apparently made the same mistake.

Here is the Chat GPT confirmation of …

If you try to present ChatGPT as a “gold standard” for producing “fact-checked truthiness” you will either :
a) be laughed at … a lot … and I really do mean a lot …, and/or
b) have people legitimately questioning your sanity

ChatGPT is one of the latest “most likely next word” software programs.

One example of just how “gold standard” ChatGPT is came from El Reg (AKA “Vulture Central”) around 5 months ago (direct link), which included :

At this point it seems the AI was doubling down on the lie by mentioning reputable media outlets in an attempt to make the story more believable. So I asked ChatGPT, “Can you provide a link to the Guardian obituary?” expecting it to finally give up the lie but to my concern it went even further:

Yes, here is the link to Alexander Hanff’s obituary on The Guardian’s website:

Now ChatGPT was outputting fake links to articles that have never existed – why?

NB : My guess is that you would consider the Graun to be a “reputable” media outlet. Other people here (and elsewhere) may disagree …

Programs like ChatGPT, which merely output the character string that will “probably” come next in its output, have a proven tendency to … if you’ll excuse the technical jargon … “just make shit up”.

. . .

WUWT should be the gold standard …

Neither WUWT nor Willis (nor I, nor anybody else) is responsible for your erroneous assumptions.

… if it expects to convince the climate community.

Having admonished you for “unwarranted assumptions”, I will now immediately make the assumption that the members of “the climate community” that you hold in the highest regard are precisely those for whom Upton Sinclair’s astute observation about human nature that “It is difficult to get a man to understand something, when his salary depends on his not understanding it” applies.

My opinion is that WUWT is aimed more at “convincing” members of the general public, including (but not primarily) “interested amateurs” like myself, rather than “the climate community”.

NB : It is always possible that ***I*** might be wrong on this specific point.

Instead of loftily pontificating on what other people “should be” aiming for, why not limit yourself to expressing your opinions instead, while keeping sufficient self-awareness to be able to admit to yourself (at least) that you may be wrong (/ misinformed).
