# The New Pause lengthens by another month to 5 years 7 months

By Christopher Monckton of Brenchley

The New Pause continues. To the end of December 2020, it was 5 years 4 months. To the end of January 2021, it was 5 years 6 months. To the end of February 2021, it is 5 years 7 months:

Up to December 2020, for which I have data for two satellite and two terrestrial datasets, UAH and RSS showed the shortest Pause, while HadCRUT4 shows the longest, at 6 years 6 months:

The difference between the lengths of the New Pause in versions 4 (6 years 6 months) and 5 (5 years 8 months) of the HadCRUT dataset to December 2020 is a whopping 10 months, which the newer version wipes off the New Pause. As Willis Eschenbach has recently pointed out, the tamperings between versions 4 and 5 chiefly affect recent years: for once, the earlier years of the HadCRUT dataset have been left comparatively unadjusted. Could it possibly be that the emergence of this new Pause is giving the usual suspects – er – pause for thought?

The two satellite datasets, UAH (trustworthy) and RSS (run by a “scientist” who resorts to hate speech, calling those of us whose research suggests small and harmless global warming “climate deniers”), continue to show very different warming trends. From 1979-2020, RSS, at 2.16 C°/century equivalent, shows 58% more warming than UAH. Settled? Schmettled.

Charts are below. For interest, I have also added the chart of the Central England Temperature Record from 1979-2020, which, being a regional record, shows how trivial the trend is when set against the annual winter-to-summer temperature cycle. It shows warming equivalent to almost 3 C°/century, but that is a regional and not a global mean, and the discrepancy between the regional and the global average is not entirely unexpected given poleward advection. The CETR showed warming at 4.33 C°/century equivalent over the 40 years 1694-1733, and has not shown warming at or above that rate in any 40-year period since then, so there is nothing unprecedented about the recent warming rate.

I’m taking bets on which of the various datasets will be the next to produce sophisticated excuses for the next tamper-tantrum, resulting in yet another hike in the apparent warming rate.

Finally, now that we have HadCRUT5, I have taken uncertainty intervals for each of the five mainstream climatological parameters (green) and added them to the table that shows how equilibrium doubled-CO2 sensitivity (ECS) is derived from them:

The current generation of models predicts ECS on 3.7 [2.0, 5.7] K. In reality, based on real-world observation rather than artfully profitable speculation, ECS will fall on 1.0 [0.8,1.4] K. And that is far too little to require any mitigation whatsoever. Cancel COP26! Shutter IPCC! Climatology’s predictions are about four times reality.

But can it really be as simple as this to derive ECS? Don’t we need complex models costing billions? Don’t we need multi-thousand-page IPCC reports every few years? Well, no, we don’t. The equations for the energy-imbalance factor Γ, for the implicit anthropogenic equilibrium sensitivity ΔE1 in the industrial era from 1850-2020 and then for ECS ΔE2, though very simple, are a reasonable and robust method of deriving ECS reliably from Their own recent, mainstream data, updated in a series of papers intended to be in time for IPCC’s Sixth Assessment Report.

The last line of the table is particularly interesting. It derives the unit feedback response –the response per degree of direct warming – from 1850-2020 (U1). Then it compares U1 with the feedback response U2 from 2020 to warming driven by a forcing equivalent to doubled CO2 compared with 2020.

U1, which at midrange is actually negative, at –0.06, indicating very slightly net-negative feedback in the industrial era, and not the grossly net-positive feedback imagined in the models, is 1 less than the industrial-era system-gain factor A1, the ratio of period equilibrium sensitivity ΔE1 to period reference sensitivity ΔR1, where ΔR1 is 0.3 times the period anthropogenic forcing ΔQ1.

There is little more than 2 degrees’ difference between temperatures in 1850 and at doubled CO2 compared with 2020. Therefore, U2, the post-2020 unit feedback response implicit in the model-projected ECS, ought to be about the same as U1.

At most, the ratio X = U2 / |U1| of the two unit feedback responses ought not to exceed about 1.1. But the interval of unit-feedback-response ratios X implicit in the models’ global warming predictions is an astonishing and manifestly untenable 39 [14, 69].

Just for fun, we calculated what X would be if the sillier and more extreme papers predicting 10 degrees’ ECS were true. Then X would exceed 130: that is, X would exceed any reasonable value by two orders of magnitude.

Couldn’t climatologists have done these simple sums for themselves and realized how grievously overblown their profitable but damaging predictions were? Why did they ever imagine that ECS would be anything like 3 or 4 degrees at midrange, when in reality it will be a harmless and beneficial 1 degree (and only that much on the generous assumption that the official estimates of greenhouse-gas forcings are not overstated)?

The reason is that they imagined that the 32-degree natural greenhouse effect comprised only two components: 8 degrees’ reference sensitivity to preindustrial noncondensing greenhouse gases and 24 degrees’ feedback response thereto (see e.g. Lacis et al., 2010). On that basis, they thought that 1 degree of doubled-CO2 reference sensitivity would become about 4 degrees’ ECS – and the current models’ midrange prediction is indeed close to 4 degrees.

They had forgotten that much of the 24 degrees’ total preindustrial feedback response was a response not to the preindustrial noncondensing greenhouse gases but to the 25-times-greater emission temperature that would prevail near the surface even if there were no greenhouse gases in the air at the outset. The larger the feedback response to the warmth from the Sun, the smaller the feedback response to the greenhouse gases.

Bless their little cotton socks, they had forgotten the Sun was shining. That strikingly elementary error is why the world is in a childish panic about global warming.

Great posting of another analysis, Lord Monckton. However, you should start sleeping with one open as San Fran Pelosi has just passed HR-1 in the US House of Representatives, and she states that “HR-1 will eliminate misinformation about climate change”, and I’m guessing she isn’t talking about science as we know it. This ridiculous bill now goes to the Senate, where it might encounter resistance sufficient to stop it. Or not. Stay tuned.

There is a section in the bill that makes it illegal to give out false information about elections, with the Democrats determining what is false and what isn’t, of course.
Perhaps that is the source of the confusion.
Anyway, once the Democrats have full control of the government, bills to outlaw saying anything a progressive disagrees with will soon follow.

Tom Abbott

“once the Democrats have full control of the government, bills to outlaw saying anything a progressive disagrees with will soon follow.”

I think that’s right. A lot will depend on a few Democrats in both the House and the Senate who have conservative constituents that they can’t alienate too much.

The Democrat Senator from Arizona stopped the \$15 an hour pay increase by voting no. Senator Machin says he will not vote to stack the Supreme Court, so he may not vote to impose censorship on the Right, either.

There are a lot of vulnerable Democrats in the House elected from conservative districts and they are going to have to pay attention to what their people want and the pressure on the representatives will increase as the 2022 elections get closer.

We are close to a one-party, authoritarian government, but it’s not a done deal yet. Keep fighting back. We still have legal ways out of this mess.

Great posting of another analysis…

Really?

It is absolutely evident that, when a period in a time series starts with or near to the period’s highest value, the linear estimate for the period automatically becomes way lower than if the period starts behind that highest value.

For UAH 6.0 LT

Aug 2015 – Feb 2021: -0.01 ± 0.12 °C / decade

Now the estimate for the period beginning 12 months later

Aug 2016 – Feb 2021: +0.24 ± 0.16 °C / decade

Moreover, the linear estimate for the first period ingeniously chosen above has no meaning at all: the standard error is way higher than the estimate itself.

In my native tongue, such behavior is named ‘miroir aux alouettes‘, i.e. a mare’s nest.

Richard Barraclough
March 8, 2021 3:34 pm

Exactly ! I don’t think one should read too much into a 5-year negative trend. Such trends have happened several times within the overall dataset, and we just happen to be in another one now.

If you calculate the 60-month trend for each of the 448 overlapping such periods in the dataset, you find 189 of them have a negative trend, and 259 have a positive trend. The months with a negative trend occur in 6 groups each a year or two long, as you might expect from glancing at the graph.

There’s no reason to expect that the current negative trend, calculated on this basis, will last any longer than another few months

Gordon A. Dressler

OK, it’s easy enough to run this issue to ground.

One can review and even download the full text of H.R.-1 For the People Act of 2021 at this URL: https://www.congress.gov/bill/117th-congress/house-bill/1/text

I did this and then did a simple computer search for the word “climate” (both directly on the website’s text and also on the 791-page downloaded PDF copy) . . . guess what, not a single “hit” for this word appearing anywhere in the bill’s text in either case.

I invite everyone else to do this to see where, in fact, the truth lays.

Nancy Pelosi may have interpreted the text of the bill as giving her the right to do anything she wants, such as censoring people discussing “climate change” (whatever that actually means to various people), and saying such publicly, but such IS NOT IN THE BILL.

How cold do expect March to be?

If it’s 0°C the pause will start in June. If it’s -0.1°C it will start in May.

If it’s -0.67°C (the coldest ever anomaly) the pause will start in March 2015, making the pause 6 years and 1 month old.

Here is a handy look up table to guess where the pause will be starting after the March UAH update

```March Range      Pause Start   Pause Length
----------------------------------------------------------
+0.39 - +0.54    Sep 2015      5 Years 7 Months
+0.13 - +0.38    Aug 2015      5 Years 8 Months
+0.05 - +0.12    Jul 2015      5 Years 9 Months
-0.08 - +0.04    Jun 2015      5 Years 10 Months
-0.37 - -0.09    May 2015      5 Years 11 Months
-0.56 - -0.38    Apr 2015      6 Years 0 Months
-0.76 - -0.57    Mar 2015      6 Years 1 Month
```

There may be some minor differences around the edges, depending on rounding errors and minor changes to earlier UAH data

Richard M
March 5, 2021 5:47 am

I also expect a large drop next month to match the drop in the SSTs which usually foreshadow the UAH move 3 months later. SSTs had a big drop in December 2020. I would guess it will drop to around zero using the current baseline.

The bigger question is how long will this La Nina run. If it goes for another year then the pause will start stretching back to 2012 making it a full decade.

Bellman
March 5, 2021 6:34 am

If it goes for another year then the pause will start stretching back to 2012 making it a full decade.

I think you would need temperatures similar to 2008 for that to happen within a year. But so far 2021 has been almost half a degree warmer than 2008.

I agree, this month’s data will likely show a sharp decline and atmospheric effects from this La Lina are already expected to last until June.

– Christopher Monckton of Brenchley

In the many decades that I have been involved in the “global warming” / “climate change”/ “wilder weather”/ “we’re all gonna die from false fabricated climate BS” / debate, I’ve watched rationally calculated ECS decline from almost an order of magnitude, from almost 10C to about 1C/(2xCO2).

My own calculations of ECS range from Plus1C/doubling to Minus1C/doubling, based on the ASSUMPTION that increasing atmospheric CO2 drives temperature, which is probably FALSE – unless the future can cause the past, which is extremely improbable in our current space-time continuum. I suggest that ECS, at best, should be treated as an “Imaginary Number”. 🙂

The following post is from 2013.

[To spare our hardworking moderators more work, I’ve deleted links – see the original post for links.]
[excerpt]

One could also say “an infinitude of worthless climate models”, programmed by “an infinitude of dyslexic climate modellers”, yielding “an infinitude of exaggerated global warming predictions” (er, sorry, “projections”).

John said above:
David Appell had the first comment on Judith’s blog entry, which is entitled “Consensus Denialism.” Here is what he said about Judith:
“The distressing thing is how some people are all ready to attack models, instead of helping make them better.”

OK David, here are some helpful suggested steps to make the climate models better:
1. Adjust the Surface Temperature (ST) database downward by about 0.05 to 0.07C per decade, back to about 1940, to correct for a probable strong warming bias in the ST data.
2. Decrease the ECS (sensitivity) to about 1/10 of its current level, to between 0.0 and 0.5C. If ECS exists, it is much smaller than current estimates.
3. Eliminate the fabricated aerosol data to enable the false high ECS values used in the climate models. The aerosol data was always provably false (Google “DV Hoyt” ClimateAudit).
4. Include a strong natural cyclical variation based on either the PDO (~60 years) or the Gleissberg Cycle (~90 years) – see which one fits the ST data best.

Other than that, the models are great! Actually no, not so great – the models have probably “put the cart before the horse” – we know that the only clear signal in the data is that CO2 LAGS temperature (in time) at all measured time scales, from a lag of about 9 months in the modern database to about 800 years in the ice core records – so the concept of “climate sensitivity to CO2” (ECS) may be incorrect, and the reality may be “CO2 sensitivity to temperature”. See work by me and Murry Salby.

BTW, this does not preclude the possibility that increases in atmospheric CO2 over the past ~century are primarily due to human combustion of fossil fuels, but there are other plausible causes – (Google “mass balance argument” Engelbeen and Courtney).

So good luck with those models David =- hope this helps to make them better. 🙂

My search for “GISTEMP” in the article comes up 0/0 and our good friends in the so-called popular press usually quote GISTEMP data and GISTEMP’s Land Ocean Temperature Index (LOTI) shows that the new pause goes back to November 2018.
Source:
https://data.giss.nasa.gov/gistemp/tabledata_v4/GLB.Ts+dSST.txt

But that is a pause of 2.16 years years and counting. In a few days GISTEMP will come out with LOTI to include data from February 2021 and probably the expected 300 or so changes to the monthly entries all the way back to January 1880. So who knows?

However should this new pause actually get some press, the folks at Skeptical Science are sure to dust off their “Escalator”:

Mark BLR

… GISTEMP’s Land Ocean Temperature Index (LOTI) shows that the new pause goes back to November 2018

For GISTEMP (LOTI) the “trend” for the monthly anomaly data from June 2015 to January 2021 is +0.01°C/decade.
From July 2015 to January 2021 it is -0.02°C/decade.

The “new pause”, i.e. the longest zero (or very slightly negative) trend up to the latest datapoint period, for GISTEMP (LOTI) therefore “goes back to” July 2015, not November 2018.

It looks like the escalator might be somewhat valid. It could be that the global temperature does change in a step wise function, pause-step-pause-step-pause-step and so forth.

Note that the last couple of steps are quite a bit smaller than the previous ones shown in the animation. Note also that the most recent step looks about half the size of the one before and that one is similarly smaller than its predecessor.

My wild ass guess is that the next step on the escalator will be downward.

So much wishful thinking. You can blame Monkers for this, his now monthly (god forbid) pause update is quintissential disinformation. How many times does he need to have his cherrypicking, “no warming” arse debunked before he dies of shame?

There are no steps and there is no pause. If they were a thing you’d see it in the ocean data where 93% of the warming has occurred.

So many pauses, so many steps. 2.3% lol.

If we accept that most of the heat goes to the ocean, we also have to accept that most of the CO2 is in the ocean.

If the ocean is getting warmer, that means it can hold less CO2. The amount of CO2 in the atmosphere is determined by Henry’s Law not vice versa.

It is a reasonable hypothesis that the increase of atmospheric CO2 since the end of the Little Ice Age is explained by the warming of the oceans and that human CO2 emissions are tiny and ineffectual given the vast reservoir of CO2 in the oceans.

Loydo
March 6, 2021 2:32 pm

The ocean is a net CO2 sink and has been since humans started raising the atmospheric concentration. The CO2 concentration in the ocean is increasing, not decreasing.

Nonsense, you made that up. From 1980 until now CO2 concentration has risen from about 340ppm to 420, a rise of about 624Gt. Humans emissions over the same period are double that, forcing the ocean to behave as a net sink.

Loydo,

You have obviously made the sophomoric mistake of confusing energy content with sensible temperature.

The above article discusses and presents graphs and ECS values that all cite sensible temperature (not ENERGY), and yet you reply to it with discussions of ocean energy content (not TEMPERATURE) with your single chart having its vertical axis in zettajoules.

“Warming” is an indication of positive temperature change, not necessarily a change in energy content . . . for example, ice changing to liquid water is a large increase in internal energy per kilogram, but occurs at constant temperature at a given pressure.

Physics 101.

Loydo

Gordon A. Dressler

Loydo, OK, let’s play your game. Your own post’s circle area chart (no credit given from where you “borrowed” it from, of course) shows 2.3% “global warming” going into the atmosphere versus 93.2% going into the ocean.

So, on what planet is 2.3% of anything considered as “statistically insignificant (atmospheric) noise”? Careful before you try to answer this . . . keeping in mind the billions of dollars and untold number of “scientific” labor hours spent debating and publishing papers relating to just the difference between 0.03% and 0.04% concentration of CO2 in Earth’s atmosphere.

BTW, if this was your attempt to deflect me for previously drawing attention to your mistake of confusing heat content with temperature, it too comes across as being sophomoric.

“When you find you’re digging yourself deeper and deeper into a hole, the first rule is . . .”

Finally, it is not what I think, but what the facts are.

Realists do not believe the climate began in 1970.

The current warming trend began in the 1700’s ( and does not correlate with CO2).

Going back 4-5,000 yrs, the Earth is in a cooling trend, interrupted occasionally by warm periods (eg, Roman and Medieval Warm Periods, and the current 200 years of moderate warming.)

Go back 2 million years. There have been multiple deep cold periods (“ice ages”), each lasting greater than 100,000 yrs, interrupted by brief warm periods of 10 to 20 thousand years. We are about 10,000 yrs into the current relatively warm period.

Go back tens of millions of years. The Earth was many degrees warmer. CO2 levels were as much as 10 times higher. Life on Earth thrived. There was no “tipping point”.

To understand climate, one must be able to zoom in and out of these different time scales or perspective is lost. On a geologic scale, the minute warming of the last few decades is trivial.

Only hysterics or people who hate people and love to dwell on “the end is nigh” apocalypses buy into the nonsense——or corrupt people with an agenda——or simple fools with no understanding of real world science, poor souls.

Meanwhile Tropical Tidbits 3.4 ENSO region graph shows temps continue to rise in the 3.4 region ever since sunspot 2804 moved to the back side of the sun, and southern sunspots 2806 and 2807 grew in size.. Every 6 hour update since 2804 moved to the back has shown a rise in temps. …

Imo, temps in the 3.4 region will continue to rise until sunspots start forming in the northern hemisphere. Note that on the TT graph that temps started dropping after February 19th. That is when sunspot 2804 appeared in the north. Temps fell from February 19th to March 2nd when sunspot 2804 moved around to the back side of the sun. Now with two sizeable sunspot groups in the south temps in the 3.4 region are rising.

For me it is always amazing to see that people who use to discredit NASA and NOAA all the time for publishing too ‘warm’ temperature series, suddenly agree in their results whenever these show… cooling:

But other sources speak a different language, e.g. Australia’s BoM:

Keep an eye on how the 3.4 region reacts to sunspots. That is the crux of my comment. Imo, temps will rise in the 3.4 region as long as sunspots are dominant in the south, and until strong sunspots pop up in the northern hemisphere. My theory is that sunspots directly affect temp shifts in the 3.4 region.

To convince, I generated this graph out of the data available at SILSO and at Canada’s Solar radio flux:

If you have lots of sun spot data at hand, you could compare that data with e.g. HadSST3’s grid data over 5S-5N — 170W-120W, and produce a graph comparing spots and SSTs.

I am back from close call #13 in my life’s saga. After 7 days of dialysis I feel like a new man, and my mind is sparky. So here goes chapter 3 in my life. Looking back at Oulo’s chart, and TT’s 3.4 chart I see that my concept is still in full play over the last 12 days which I spent in the hospital. Note that from March 3rd to March 10th temps in the 3.4 region rose as sunspots crossed in the southern hemisphere the entire time.

On March 10th a sunspot (2608) appeared in the northern hemisphere as the last spot disappeared in the south. Note how temps moved sideways on TT’s chart at that point. Then spots in the north of the sun stayed predominant from then on, and by great coincidence temps in the 3.4 region have dropped ever since as sunspot 2608 crossed in the northern hemisphere. A new spot 2810 has just appeared in the north. So temps in the 3.4 region should continue to fall.

It’s fine as it goes, we are still in solar minimum, there is a laNina (not particularly strong, not yet) so not much surprise there.
In the long term global warming has mutated to climate change regardless of warming, pause, cooling or even blid..ng freeze, the CO2 mighty mol is guilty of anything going on.
For time being fire should be directed at the climate change gangsterism and damage it does to the planet and in particular to the poor third world countries.

Even if Climate Catastrophe were true, or if you’re just trying to humour the Alarmists or distract them from their disastrous policies – don’t ever suggest weather modification, especially if it involves dumping crap in the atmosphere. Much better to let the plants and plankton enjoy the sunshine and all the free CO2 we are giving them, and spice things up for them with a tiny bit of iron dust spread out over the oceans to make the plankton happy and have a good appetite so they grow faster and suck up extra CO2 (not that there is anything wrong with CO2 but it’s comforting to alarmists and those afraid of clowns and Santa), and become a bounty for the whole food chain above them. Much cheaper than carbon taxes and unreliable green tech, shuts up the bed-wetters, helps restock the fisheries of the world, and actually helps the environment.

As 5 years and 7 months is carefully chosen to be the earliest start date to give a negative trend, then starting any point before that will give a positive trend.

What’s amusing is that because this is such a short period to look for a trend, and because it starts with such a massive increase in temperatures you don’t have to go back very far to see much faster warming trends. Start at the start of 2015 and you are warming faster than the average trend over the entire run, go back just another year and you are warming twice as fast as that, over 3°C / century. .

Fair enough, we get the point, but the purpose of the exercise with pauses is that with the assumption of the alarmists’ idea of CO2’s affect on temperatures and with the ever increasing CO2 levels, one would not expect long stretches of flat temps. One would expect the temps like from 1975-1998, not the almost flat trend from 1998 until now, in light of the huge increases in fossil fuel use. And in the end, 1 or 2 degrees of warming by 2100 sounds comforting, considering the disastrous effects of cooling like in the early 1300s. I would gladly accept Southern Ontario becoming like Bali, rather than Edmonton (no offense intended, Eskies and Oilers fans, I’ll gladly admit you’re made of stronger stuff) .

Weekly_rise
March 5, 2021 12:41 pm

“the assumption of the alarmists’ idea of CO2’s affect on temperatures and with the ever increasing CO2 levels, one would not expect long stretches of flat temps.”

This assumption is inaccurate for a couple of reasons. First is because the temperature record contains a combination of signal+noise, and the noise in the climate is quite large. We need to look at very long periods of time before the signal to noise ratio is high enough that we can clearly distinguish the underlying trend. If a trend depends exclusively on the years you pick as the end points of your trend line, you’re not looking at a long enough time period (this is a general rule of thumb – you can use statistical approaches to determine whether a trend is significant – you will likely not be surprised to learn that Mr. Monckton’s trends do not pass tests of statistical significance).

The second is that CO2 is not the only driver of earth’s climate. CO2 is said to be driving the long term warming trend since the mid-20th century, but there are other forces on various time scales that have an impact as well, both positive and negative (changes in solar output, decadal cycles in ocean temps, volcanic activity, etc.). It is the sum of all these forcings that produces observed changes in temperature. So even beyond the random year to year variability, there can be longer term swings superimposed on the gradual background warming.

Horse hockey. You are trying to repeat talking points but you have them wrong.

A Temperature trend for the globe, whether it is right or wrong, IS NOT CLIMATE! It can not define climate in any shape or form. Climate includes temperature, rainfall, soil type, altitude, geography, flora, fauna, etc. All kinds of different parameters. It’s possible to pass through different climates in just a short distance while ascending a mountain.

Climate change based on a single parameter is a misnomer from the start. If anything, it should simply be called temperature change!

The climate in general is the signal, random variability (“weather”) is the noise.

You haven’t a clue. Noise is an extraneous frequency to what you are examining. In your terms, “climate” is the signal. It isn’t. It is the frequency, i.e., temperature you are examining. The fact that you want to average it and call that average some new phenomena is not relevant. You are examining temperature, not climate. The natural variability is actually variance in the temperature, it is not noise. That variance should be calculated and prominently displayed with any average so one can tell how well the average represents the entire scope of data.

There is no global warming. There is no pause. Earth’s surface temperature to the best of human’s ability to measure it is STABLE.

Earths surface energy balance is controlled by two powerful highly temperature sensitive processes; formation of sea ice at the poles and convective instability in the tropics. Both temperature limits have been documented for decades.

Let me try to clarify. Lord Monckton calculates trends for CET using monthly temperature values. This is a mistake, and means you get a faster rate of warming than if you used annual data.

Why is this a mistake? Because CET data is presented as actual mean temperatures, rather than monthly anomalies. England has seasons, it’s colder in the winter than it is in the summer, and these season fluctuations are bigger than any trend, as is pointed out in the head post.

This matters because the seasonal variations will increase or decrease the trend, depending on where you start the calculation. As the year starts in January, this is being used as the start point of the trend, but this means the first few months of the trend will be cold, whilst the hottest months will be in the second half of the year, and this means the trend will add an artificial warming to the trend.

This would be very obvious if you only looked at a single year, you will see a very large artificial trend. (For example, the trend for the 12 months of 2020 is equivalent to a warming rate of 270°C / century, a rise of 2.7°C on the year). But even when averaged over 40 years you are still seeing a noticeable increase in the trend. I estimate, empirically, that this is adding around 0.2 – 0.3°C / century to any 40 year calculation.

This can be seen by converting the monthly temperatures to anomalies to remove the seasonal fluctuation, or by using Annual average temperatures.

Bellhop, who works himself up into a lather every time it is pointed out that there is a Pause in global temperatures, seems not to understand that if one sticks with the actual data, and uses the same basis of calculation for 1694-1733 as for the most recent 40-year period, the comparison will be fair. There was not as much warming in the past 40 years as there was from 1694-1733. Get over it.

Bellman
March 5, 2021 3:52 am

The CETR showed warming at 4.33 C°/century equivalent over the 40 years 1694-1733, and has not shown warming at or above that rate in any 40-year period since then, so there is nothing unprecedented about the recent warming rate.

Aside from the cherry-picking of dates and ignoring the huge uncertainty in CET at the time, the rate of warming at the end of the 17th beginning of 18th century has a lot to do with the fact you are starting at particularly cold decade. The rate of warming might not be unprecedented, whatever that means, but the temperatures are.

Average temperatures between 1694-1733 was 9.1°C, average temperature 1981-2020 was 10.1°C.

I do find it strange that people here will constantly go o about imperfections in modern data sets, will happily use any arbitrary trend in CET, even from the 17th century if they think it proves their point. The original CET was an amazing piece of research, but making exact comparisons with data that is so uncertain is really over selling it.

For context, here’s what Manley says about the early CET figures:

For the first six decades to 1720 the figures are printed in italics as an indication that they must be considered less reliable, based as they are on extrapolation from the results of readings of highly imperfect instruments in uncertain exposures at a considerable distance, generally in south-east England; or on estimates based on interpretations of daily observations of wind and weather.

Estimates, however, are still necessary for much of 1671, for July 1677 to August 1678, June to August and November 1695, June and November 1696, June 1697. From 1707 onward, although there are several English sets of daily observations in increasing detail … very few thermometer readings have yet been found. A general control for 1707-1722 is best established from a careful analysis of observed snowfall frequency and from the overlapping series of monthly means representative of Utrecht in Holland, coupled with wind directions. Values from central England for 1707-1722 are again rounded to 0.5 deg C.

Clyde Spencer
March 5, 2021 8:00 am

You are right that, to be rigorous, the end-points of a trend should use the best estimate available of the temperature uncertainties and provide a range of probable slopes. However, you should be prepared for the possibility of a negative (cooling) slope.

Hi Bellman.
For what it’s worth, I analysed the CET Summer mean monthly (JJA) and found that the decade from 1771 to 1780, the ave temperature was 15.85 deg C. Now compare that with our last decade, 2011 to 2020, of 15.98 deg C. The 1780 decade was the fourth warmest behind 2000 (15.89 deg C), 2010 (16.10 deg C) and 2020 (15.98).

Bellman yet again displays his striking ignorance. If he would only read a little history he would be aware of how very cold the Little Ice Age was in Europe. Therefore, the rapid rise in temperatures shown in the Central England record for 1694-1733 is well supported by everything from accounts of frost fairs on the Thames to Dutch Old Master paintings, followed by the milder weather we have been fortunate enough to enjoy since that very cold period.

Just as IPCC likes to use the argument that the models, though flawed, are the best we’ve got, so I use the argument that the CETR is the best regional record we’ve got for the end of the Little Ice Age.

Hey, Lord Monckey, you destroyed him!

So while we know that period was rather cold, we don’t know how cold it was (using solely historical sources). Furthermore, the rate of change was so slow people didn’t notice it in their lifetimes.

I know it was very cold at the end of the 17th century, that was my point. According to CET it was increasingly cold during that time, then suddenly was a lot less cold. Twenty years later it warmed again to temperatures that wouldn’t be seen again until the 20th century.

Therefore, the rapid rise in temperatures shown in the Central England record for 1694-1733 is well supported by everything from accounts of frost fairs on the Thames to Dutch Old Master paintings, followed by the milder weather we have been fortunate enough to enjoy since that very cold period.

One again with the frost fairs! I don’t think there were any frost fairs in London during the 1690s, the big one was in 1684, but you don’t include that in your warming trend. There was one in 1716, half way through your warming trend, and a really big one right at the end of this warming period, during the coldest year in the CET record.

Lessons from this are that, frost fairs are not a very reliable way of quantifying annual temperatures, and that Central England Temperature is very chaotic and difficult to establish how reliable any trend – modern or ancient.

…so I use the argument that the CETR is the best regional record we’ve got for the end of the Little Ice Age.

I agree, I love the CET, but you do have to understand it’s limitations, and that means not making arbitrary comparisons, especially of trend, with no regard for the uncertainties.

You are correct in this, but the Central England Instrumental Temperatures Data set is far more than just a regional record–it spans the globe.

One amusing aspect of the 1694-1733 fastest ever warming trend is that it includes a pause lasting over 20 years. Between 1702 and 1725 the trend is negative.

Burl Henry
March 8, 2021 5:35 am

Bellman:

The 1694-1733 warming was caused by periods of reduced volcanic activity. For example, there are no VEI4 eruptions recorded for between 1694 and 1707.

The period 1727–1739 was also free of eruptions.

There were no dimming volcanic SO2 aerosols being spewed into the atmosphere during those periods.

You are misusing the meaning of “cherry picking.” If one makes a claim that the slope of a line between points B and C is zero, and you come along and remark that the slope of the line between A and C is greater than zero, that is cherry picking. It also is a non sequitur because the original claim you are trying to falsify never mentioned point A. It might also qualify as a straw-man argument.

Bellman
March 5, 2021 9:01 am

So why do you think Lord Monckton chose 1694 as his starting point for the great warming 40 years? It’s because he’s looked at every other starting point and seen that gives him the greatest bang for his bucks.

If one makes a claim that the slope of a line between points B and C is zero, and you come along and remark that the slope of the line between A and C is greater than zero, that is cherry picking.

Your logic escapes me. I’m the one pointing out there is a long pause during Monckton’s fast warming period, is it me or is it him cherry-picking?

Cherry-picking in this context means deliberately choosing specific dates to demonstrate a particular outcome.In this case to choose the start date that gave the fastest rate of warming over a 40 year period.

It all comes down to definitions. If you ask the question, “Have there been any periods greater than two years during which the slope of the trend line has been zero?”, then it doesn’t require “deliberate choosing.” It just requires building a table of slopes for the database being used, and identifying the period(s) that meet the stated criteria. An interval of time either is an affirmative answer to the question or it isn’t. There is nothing special going on! And, it makes perfect sense to start with the most recent data and work back in time if one wants to risk extrapolating into the future.

Bellman uses the climate-Communist meme catchphrase “cherry-picking”. However, when the totalitarians of the Nazi Party wrote a book “100 scientists against Einstein”, who had made the then-fatal error of choosing Jewish parents, Einstein replied that if there were anything wrong with his theory of relativity a single counterexample would suffice.

Likewise, to demonstrate the falsity of the climate-Communist notion that the recent rate of warming is “unprecedented”, only a single counterexample is necessary. In this circumstance, one is entirely free to choose any counterexample one wishes to choose. Therefore, Bellman’s characteristically poisonous and malevolent allegation of “dishonesty” is as false as everything else he writes here.

Bellman
March 6, 2021 8:24 am

Einstein replied that if there were anything wrong with his theory of relativity a single counterexample would suffice.

What he’s supposed to have said is along the lines of “Why 100, If I were wrong, then one would have been enough!”. He’s supposed to be talking about the number of authors, not the number of counterexamples.

But, there is a clear distinction between logical arguments – one counterexample disproves a theorem, and statistics, where a single piece of data never proves or disproves anything. The best you can do is show it’s very unlikely that a result would have happened by chance, but if you pick the data to prove your point, ignoring data that shows a different result, any significance test goes out the window.

Your broader point that you can use 1694 to demonstrate that the rate of warming in central England isn’t “unprecedented” would be OK if anyone had made that point. But I suspected that all claims of unprecedented warming are talking about global not local temperatures.

Tim Gorman

You sort of described how you really need to analyze a time series! Anomalies used to build a time series hide the variance of the underlying data and therefore linear trends tell you almost nothing about what is actually happening. What you have described is kind of like using first differences to turn the non-stationery time series into a stationery one conducive to using trend lines with. My guess is that you will find cyclical impacts from the oceans.

As usual, Bellman, who is handsomely paid by a climate-Communist front group to try to disrupt these threads, displays the militant ignorance that goes with the conformist, totalitarian mindset.

We are often told by the climate fanatics that the rate of global warming is “unprecedented” – oh, and to instruct the ignorant Bellman on what a rate of global warming is, it is the change deltaT / deltat in temperature over time. It is, therefore, necessary to find only one counterexample to demonstrate that the recent warming in most of England is not unprecedented. That is not how totalitarian politics works, but it is how science works. Get used to it,

I’m making no claims in any of these comments about what caused the warming. If rising CO2 is affecting the warming in Central England it’s only indirectly – there are many more factors that can cause long term changes in a small part of the globe, especially a part that has such an unusual set of climatic conditions. That’s one reason why I don’t think it makes much sense to compare the changes in the 17th and 18th centuries with changes in the 20th and 21st centuries.

On the other hand I wish you would provide some evidence to a claim that there is zero indication.

I’ll get back to you on the actual r^2 value. I may have made a mistake somewhere, as I’ve just checked it again and it’s now showing up as 0.25. Will have to do redo this when I have more time. In any event why you are talking about odds and probability – that’s not what r^2 means.

What you should be asking is, is the correlation statistically significant, and the answer is yes.

Bellman

Clyde Spencer
March 6, 2021 10:57 am

At an r^2 of 0.5, 50% of the variance is predicted by the independent variable — the same odds that a head or tail will come up on a coin toss. Unless it is a multivariate relationship, and one has the data for the other variables, the independent variable time has no utility for predicting future dependent variables.

Bellman
March 6, 2021 12:20 pm

Again, this has nothing to do with probability. The r^2 value, as you say indicates how much of the variance is predicted by the independent variable. An r^2 value of 0.5 is not saying there’s a 50% chance of anything happening. It’s roughly saying that if the variance in the dependent variable was, say, 2, once we factor in prediction from the independent variable it would be reduced to 1.

Tim Gorman
March 6, 2021 2:31 pm

Bellman,

Again, this has nothing to do with probability.”

Huh? Variance *is* associated with probability.

” if the variance in the dependent variable was, say, 2, once we factor in prediction from the independent variable it would be reduced to 1.”

You mean half of the variance of the dependent variable is from something other than the independent variable. That’s an indication of a poor model if half of what is causing the variance in the dependent variable is unknown.

If r^2 is 0.17 then it means that 83% of the variance of the dependent variable is from unknown factors. That’s not a good result at all! Especially if the independent variable is TIME.

Bellman
March 6, 2021 3:08 pm

But it’s nothing like tossing a coin if you have an r^2 of 0.5. I’ve really no idea what Clyde Spence means by that.

I never claimed it was a “good” result. Why would you expect most of the annual variance to be explained by CO2? There’s an awful lot going on there, and I’m only pointing out to fred250 there is more than zero correlation.

I’m certainly not suggesting this proves anything, just that there is a statistically significant correlation.

Bellman
March 7, 2021 5:52 am

The r^2 value becomes much better when you apply it to global data. For the 170 years of HADCRUT4, the r^2 value is 0.85.

Clyde Spencer
March 7, 2021 1:10 pm

If the correlation between two variables is perfect (1.00…0), then the probability that y = x is 100%. That is, the independent variable is a perfect predictor of the dependent variable.

If the correlation between two variables is zero (0.00…0), then the probability that y = x is 0%. That is, the independent variable is not a predictor of the dependent variable.

What happens in between the two extremes? Do you suppose that the relationship only exists at the end-points?

Bellman
March 7, 2021 2:33 pm

A correlation of 1 does not mean that y = x, it means x predicts y. e.g, y = a + bx. With a correlation of 1 this is true for every data point, so yes the probability that y hits the trend line is 100%

I don’t know what you mean when you say that if the correlation is 0, then y cannot equal x. If you are talking about individual values than y can certainly equal x. As you say it’s just that x is not a predictor of y.

In between as r^2 increases points get closer to the predicted value, but I still don’t know what you mean about an r^2 value of 0.5 implies there’s a 50% chance. A chance of what? You seem to be making a categorical error, like saying one horse was half the size of the other one, that’s the same odds as tossing a head with a coin.

Maybe you’re making a valid point, but I’m just not seeing it.

Clyde Spencer
March 8, 2021 2:17 pm

A correlation of 1 does not mean that y = x, …

A regression line with a correlation coefficient of 1 has a slope of 45 degrees. From trigonometry, the rise and run have to be equal.

https://www.thoughtco.com/slope-of-regression-line-3126232

Note particularly the formula for the slope (a) of a regression line.
For a correlation coefficient of 1, when the standard deviation for x and y are equal, the slope is 1 (45 deg). How are the x and y standard deviations going to be equal unless all the y-values pair exactly with all the x-values?

There are only two instances where the correlation coefficient can be zero. 1) when y is a constant and all values are parallel to the x-axis; and 2) where both x and y are random and a scatterplot generates a point-cloud with no correlation. (It is possible that x and y might be equal for one point, but if the correlation coefficient is zero, the zero-slope regression line has no predictive value. So, maybe I should say that the probability of y=x is vanishingly small for r=0.)

I suspect that the reason that you are “just not seeing it,” is because you plug numbers into a spreadsheet or statistics package without really understanding what you are doing. You are like a technician following the instructions in a repair manual, not knowing why you are told to do what you are.

Bellman
March 8, 2021 4:22 pm

A regression line with a correlation coefficient of 1 has a slope of 45 degrees. From trigonometry, the rise and run have to be equal.

Not true at all. Even your linked article says nothing of the sort.

The formula you are talking about,

$a = r(s_y / s_x)$

is saying you can derive the slope a by multiplying the correlation coefficient by the sd of y divided by the sd of x. If the slope is 2, and r is 1, then the standard deviation of y is twice that of x. a, the slope of the line, could be any size.

And none of this is anything to do with why you think an r^2 value of 0.5 is like tossing a coin.

Bellman,

Your math makes no sense. If the slope of the line is not 1 then y can’t equal x except perhaps at x=0. If the slope of your line is 2 then y will never equal x. It will always equal 2x.

Bellman
March 8, 2021 6:17 pm

You’re mixing me up with Clyde Spencer. He’s the one who thinks that y always equals x if r is 1.

The equation from his link is only describing the slope, not the intercept. If the slope is 1 and the intercept is zero than y = x for all x and y, if the slope is 1 and intercept is not zero, y will never equal x, and if the slope is not 1, y will equal x for 1 specific value. It’s pretty basic linear algebra. Solve y = b + ax, y = x.

Last edited 7 months ago by Bellman
Tim Gorman
March 8, 2021 7:10 pm

You are equivocating. The intercept is an offset that can be adjusted for.

If the slope is not the same then y can never equal x, even after the offset has been adjusted for.

Bellman
March 9, 2021 4:13 am

If the slope is not 1, then y will equal x at one point. You said that yourself, x = y = 0 will be a solution if we remove any offset. What I don’t know is how this is relevant to any part of the discussion.

First you say my maths makes no sense, then you say I’m equivocating. What you are not saying is what you think about Spencer’s claims. Is an r^2 value of 0.5 like tossing a coin, and if so in what sense?

Tim Gorman
March 9, 2021 8:21 am

Nope. If the slopes are not equal then I can’t think of a situation where the intercept will occur at y = x other than at zero.

If correlation is r^2 = 0.5 then it means that in a scatter plot you will have about the same number of points above and below the trend line. I.e. flip a coin.

Bellman
March 9, 2021 10:18 am

Nope what? As I said if you remove the offset the point where y = ax intercepts y = x will be y = x = 0. I’m really not sure what you are arguing about here.

If correlation is r^2 = 0.5 then it means that in a scatter plot you will have about the same number of points above and below the trend line. I.e. flip a coin.

Well yes, but the same is true for any r^2 value < 1.

Bellman

I’m worry about it a lot. The degree rise was merely to point out the difference between the two periods. You can say the trend isn’t significantly different, but the temperatures are. The first warming starts from a very cold time, the current warming starts from a relatively mild time. It seems unlikely that the causes of the two warming periods are the same, especially if the cold 1690s were caused by the Maunder Minimum as some claim.

Alex
March 5, 2021 4:38 am

But can it really be as simple as this to derive ECS?

We humans emit 10 Gt of carbon (CO2 equivalent) every year in a combined sink consisting of the atmosphere and hydrosphere which are in a continuous equilibrium at a ratio of approximately 1:50 of CO2 in the atmosphere and hydrosphere respectively. The atmosphere contains about 890 Gt of carbon equivalent of CO2 while the seas and oceans are calculated to have 38,000 Gt of CO2. The combined quantity of carbon contained in both the atmosphere and hydrosphere as CO2 is about 40,000 Gt.

So what are we looking at here? We are looking at an injection rate of anthropogenic carbon as follows:

0.0274 Gt C per day
0.00114 Gt C per hour
1.9E-05 Gt C per minute
3.17E-07 Gt C per second

in a sink containing ~40,000 Gt of C.

Our CO2 contribution to the global system is less than insignificant. It becomes even more significant when one realises that those ~98% of those tiny little bits of CO2 that we release into the atmosphere will eventually be absorbed by the hydrosphere as per Henry’s law.

A corollary to this is that a slight warming of the oceans will result in a substantial release of CO2 into the atmosphere, which may just be the case in this current phase of global warming.

Monckton of Brenchley
March 6, 2021 1:35 am

In response to Alex, we skeptics must not do as the climate Communists do. We must not overstate our case. It is theoretically possible for a comparatively small anthropogenic contribution to the CO2 in the coupled atmosphere-ocean system to have an appreciable effect. If the system were in approximate balance before we perturbed it, then we might disturb that balance. If one has a pair of scales with exactly ten tons on each side, if the scale is perfectly balanced and perfectly frictionless the addition of a feather to one side or another will tilt the scale.

The question, then, is not whether we are exerting an influence over the climate, but how much (or, rather, how little) influence we are exerting.

Those guys watch too many spook sci-fi movies where you get an instant ice age and tornadoes that freeze things on the spot. “Day After Tomorrow” is a good one, but any weatherman who knows his “stuff” will tell you “there is no such thing”.

Are these people really delusional enough that they think anyone notices a one-half degree of change of any kind? And if there were no grants money involved at all, would they still be harping on this stuff? (Doubtful.) Are any of them aware of their very own volume of contribution of CO2 to the atmosphere?

Those questions keep coming up, and the only reason any of them get testy about it is that their need for grants money is going to be threatened by any dose of reality.

HR-1, aka the Climate Misinformation Bill, may well turn out to be a spectacular own goal by alarmists.

To convict someone needs a court trial, so the defence gets to provide their own evidence and to cross-examine the other side.

Any contested data, claims or theories will therefore be scrutinised and debated in open court under Oath.

That’ll be interesting!

The data has to be provided by the alarmists. Skeptics say the alarmists have no data. It’s up to the alarmists to prove the skeptics wrong by providing some data. Skeptics don’t have to provide anything but a skeptical attitude. 🙂

Just one little bit of data would change the whole picture. Do the alarmists have any? They haven’t provided any to date. So far, all we get is unsubstantiated speculation and assertions from the alarmists. That doesn’t qualify as data or evidence.

The point is that according to the global warming Chicken Littles, CO2 controls Earth’s atmospheric temperature, and has been steadily rising for decades. Yet a corresponding steady rise in temperature is not seen, ergo there is something wrong with the premise about CO2.

ONLY warming in the last 43 years has come at El Nino events

..nearly 6 years of pause now,

no warming from 1980-1997, (17 years)

No warming from 2001-2015 (15 years)

So for 38 of the last 43 years NO WARMING

There is absolutely NO CO2 warming signal

And no empirical evidence to back up the fallacy of warming by atmospheric CO2.

1… Do you have any empirical scientific evidence for warming by atmospheric CO2?

2… In what ways has the global climate changed in the last 50 years , that can be scientifically proven to be of human released CO2 causation?

Which El Niños do you count as major? I’ll assume 1982, 1998 and 2016 for this.

Trend 1983 – 1997 is 0.11°C / decade.
Trend 1999 – 2015 is 0.07°C / decade.

Of course this analysis is ignoring all other ENSO effects, from moderate El Niños and LA Niñas.

how does adding one month, January, to the trend give a two month extension to the pause?

Gary Pearse
March 5, 2021 9:11 am

mkelly: Simple. It occurs when the new data point falls below a data point just before the beginning of the previous series. Imagine if the next month were to drop by 0.2C, we would connect up with the previous 18yr ‘Pause’! I don’t think the climate wroughters would permit this. They would wrought it out of existence – that would seem to be the objective of the recent changes to HadCrut in the UK.

March 8, 2021 3:12 pm

The Old Pause, which used to feature in excited articles every month, was finally squeezed out of existence in February 2016, when the trend from the last few months of 1997 turned positive.

The smallest positive trend of these months to the present is from July 1997, at 0.115 deg/decade. This is not much different from the trend for the whole dataset, which is 0.137 deg/decade.

I don’t think the Old Pause is likely to make a reappearance.

March 5, 2021 6:06 am

ECS may actually be 0.0. Here’s another way to look at the situation.

If you perform a transformation of GHG radiation in the Earth’s energy domain (atmosphere + surface) you get a rather interesting result. The transformation is: change every event (emission + reabsorption) to an average one. This would be the strength and direction of the average of all photons emitted by the surface and GHGs.

When you do this the overall energy flow should be identical. Each photon that leaves the surface will stop N times as it is reabsorbed. Each photon will travel a distance of X meters before being reabsorbed. It will take T seconds for each event to complete.

Notice this transformed system has no downwelling IR. Yet, it is mathematically equivalent to our current atmosphere. What happened to the greenhouse effect?

What will happen if you add more GHGs to this energy domain? Since GHGs already absorb all the radiation coming up from the surface that they can absorb, the most it can do on the absorption side is slow the process down slightly. N would get larger, X would get shorter and T a little longer. However, you are also adding more emitters which naturally has the opposite effect. The two would likely cancel out telling us the ECS truly is zero.

The only way to warm the system is to add more energy to it. Hence, all the warming of the last 350 years must be due to more energy coming from either ocean changes or the sun.

Richard M
March 5, 2021 8:02 am

To net this out. The lower atmosphere is not warmer because of downwelling IR. It is warmer because IR is integrated into the atmosphere and where there are more molecules to accept the energy it will naturally be warmer. Yes, GHGs are required to do the energy integration and the eventual emission out of the atmosphere.

The adiabatic lapse rate is the result of this integration of IR energy. Where gravity leads to a higher density of mass, it will be warmer. Gravity is not producing extra energy, it is just creating the structure for energy distribution.

I saw a recent paper that stated that ECS drops as the number of GHGs increase. This thought experiment explains why. The amount of unabsorbed energy decreases as the GHGs increase. The amount of warming produced continues to drop until all the energy is absorbed. After that you get no free lunch.

Some will jump in and claim that pressure broadening will add to the available energy. They are right. The problem is that pressure broadening is such a small factor that any warming would be negligible.

Jim Gorman
March 5, 2021 11:12 am

Sorry to spoil your parade, but radiation is not by photons but by electromagnetic (EM) waves. What does this mean? Photons are not bullets with a vectored direction. Molecules radiate a spherical EM wave, like a balloon and that sphere expands as it travels. The EM wave has a certain power associated with it when it is formed and from that you can calculate how much energy is available in photons. Planck visualized this as pencils sticking out from a point, I like to think of a curled up porcupine with it quills sticking out.

The upshot is two important things, one, half the radiation goes up and half down, and two, power per area is diminished by the inverse square law.

The piece I often see misunderstood or forgotten is that the sun provides all the energy in the system. The earth nor CO2 provides any independent sources of energy. Let’s also assume that all GHG;s except for water do not absorb any of the sun’s energy directly. That means there are two pairs of bodies, sun/earth and earth/atmosphere.

The sun warms the earth and the earth starts to radiate. Every time it radiates it also cools. GHG’s intercept some of the EM waves and send back half of the energy.

And here is where the misconception occurs. Warmists believe that the CO2 “back radiation” ADDS to the sun’s energy so you end up with more energy being absorbed by the earth and further increasing the temperature of the earth.

Let’s assume the sun is at its zenith and the earth and sun are at equilibrium. IOW, the earth is receiving 10 units of power from the sun and is radiating 10 units out. Remember the sun is radiating power at its own temperature and doesn’t know or care what receives it, it just keeps radiating. What little the earth radiates is not going to make the sun warmer. Likewise, the earth is going to keep radiating at 10 units because of its temperature.

Now let;s put the atmosphere in the system. Well, the earth sends out 10 units and gets 5 units back from CO2. (Not exactly right because CO2 only captures a portion of the outgoing radiation and because it is cooler it also radiates a lower power.) The end result is that the earth continues to cool, just at a slower rate. To do otherwise, CO2 would have to radiate more power than the earth is in order to reverse the gradient.

Long story, short conclusion. CO2 is an insulator. It slows heat loss which makes warmth disappear slower. That is not hotter, it is still cooling. CO2 however, can not make the earth hotter than the sun does.

Now, how about H2O? ~50% of the sun’s energy is in what is called near IR. H2O assorbs a goodly portion of this energy but CO2 almost none. Could the CO2 –> H2O feedback actually be turned around and H2O –> CO2 increases the energy of CO2?

Jim, you spoiled nothing because nothing I said is dependent on how energy is transported. It makes no difference. As I stated in my description, it is a mathematical transformation. It is a thought experiment. What the experiment shows is that the real atmosphere is equivalent to the one I described. And, as such you can elicit knowledge from a simpler paradigm.

Christopher, I relish your naughty return to the ‘pause’. The first Dreaded Pause was the single most powerful wrecking ball to the climate wroughters peace of mind and security in their ‘wreckless’ endeavors. It created a new psychological illness known as the “climate blues” that permanently terminated the careers of numerous climate scientists.

Oh, they rationalized that their depression was because they could see the terrible hot future and no one was listening. The climate blues really was nothing more than classic psychogical D*Nile. It took out those of the most delicate constitution. This is why Karl’s last ‘professional’ act before hasty retirement was Karlization of the pause.

Presently, the new pause is adding on a month at a time. How much lower must T go before it begins to conect to the earlier pause?

That was the one based on RSS v.3 data that Carl Mears had previously stated contained a known cooling bias and therefore should not be used to infer temperatures in the TLT. You did it anyway. Mayers et al. updated their temperature data set in v.4, publishing their method in the peer reviewed literature, and you promptly dropped it like a stone. You now refer to Mears, whose data you previously relied on, as a “scientist” in inverted commas. Charming.

Monckton of Brenchley

The paid climate Communist “The Final Nail”, one of several assigned to try to derail these threads, does not, perhaps, recall that I also carried regular analyses of all the datasets. The Pause in UAH, for instance, shows as 18 years 8 months. Not much of a “cold bias” in the old RSS record, then, was there?

And the reason why I ceased reporting on the Pause at the moment when Ted Cruz displayed the graph was that from the following month onward the el Nino began to make itself felt, bringing that long Pause to an end.

And the reason why I refer to sMears as a “scientist” rather than as a scientist is that he describes those of use whose research disagrees with his using the hate-speech term “deniers”. No scientist would resort to that hate speech and post it up on the RSS blog.

It’s even worse than my calling “The Final Nail” a paid climate Communist. If “The Final Nail” does not like that description, imagine how much less we whose research leads us to question the Party Line on climate like to be called “deniers”.

But, to be honest, I’ve lost confidence with any temperature data at the moment, because there isn’t one series that is entirely secure from meddling.

Poor, poor CO2 . . . it looks like it has once again (referencing the prior intervals of 1940-1975 and 1999-2015) forgot how to cause “global warming”, aka “climate change”.

More properly, as Wijngaarden and Happer (2020 preprint) have pointed out, CO2 has just became “saturated” in the cause.

It’s not that CO2 itself is saturated. As they showed in their paper, adding more CO2 will increase its energy capture. What their paper didn’t show is that that energy simply came from other GHGs (water vapor primarily). It’s the total greenhouse effect that is saturated.

Gordon A. Dressler

Don’t you love it! Happer and van Wijngaarden’s research may upset the whole Human-caused climate change applecart. That’s what genuine science does all the time. And here we go again.

And all those alarmists will have to rethink what caused all that ancient warming which they attribute to CO2. If it can only get so warm with CO2, and Happer and van Wijngaarden say we are at about that level now, and no warmer, then something else is needed to explain the much higher temperatures of the ancient past. CO2 could not push the temperatures that high. CO2 is at its limit today, according to the research.

We should probably find out if this is true or not before we go spending \$Trillions on windmills and solar. It’s its true, we don’t need to limit CO2 production.

Gordon A. Dressler

Yes, Tom, I’m anxiously looking forward to widespread critical review of the Happer and van Wijngaarden paper following its formal publication.

If it withstands objective reviews, then most “alarmist” climate scientists should backdown their assertions re: increasing atmosphere warming, which has indisputably occurred over at least the last 200 years, being caused predominately—and, more importantly, continuing to be caused—by increases in atmospheric CO2 content.

I say that they should backdown, not believing that many actually will.

Roy Langston
March 5, 2021 9:32 am

I don’t know what Monckton means by “the 25-times-greater emission temperature that would prevail near the surface even if there were no greenhouse gases in the air at the outset,” but the AGW modeling error is not in assuming only the two components, but in assuming the water vapor (condensing GHG) feedback response to non-condensing GHGs component is linear throughout its range. In reality, the feedback should be extremely large in the temperature range where most of the earth’s ocean surface is near 0C (i.e., much colder than the earth has been in hundreds of millions of years) because that is the range where additional non-condensing GHGs will cause the greatest logarithmic water vapor response (i.e., evaporation), and progressively smaller with increasing temperature above that level. Once the great majority of the ocean surface is well above 0C almost all year, as it has been for at least 650My, the equilibrium hydrological cycle is established, water vapor dominates the GHG effect on surface temperature, and non-condensing GHGs will have little effect on it. That is why the paleo proxy record shows little correlation between temperature and CO2 except to the extent that CO2 follows temperature because of the effect of temperature on its solubility in sea water.

Monckton of Brenchley
March 6, 2021 12:53 am

Let me assist Mr Langston with his elementary arithmetic. Climatology (e.g. Lacis et al. 2010) considers that about one-quarter of the natural greenhouse effect – i.e. 8-10 K – is direct warming forced by the naturally-occurring, noncondensing greenhouse gases. And it foolishly imagines that all of the 24 K preindustrial feedback response is response to that 8-10 K – i.e., that feedback response multiplies the direct warming by 3.5-4 to give eventual equilibrium warming. Therefore, current models predict 3.7-3.9 K midrange equilibrium doubled-CO2 sensitivity (ECS) in response to little more than 1 K directly-forced warming by doubled CO2.

However, emission temperature is 255 K, and it too contributes to the 24 K preindustrial feedback response. Now, 255 K is about 25-30 times the 8-10 K direct warming forced by the preindustrial noncondensing greenhouse gases. Therefore, the larger the feedback response to emission temperature, the smaller the feedback response to the preindustrial noncondensing greenhouse gases.

Bottom line: there is no basis in the preindustrail record for the assumption, explicit in paper after paper throughout the climatological journals, that about three-quarters of the preindustrial equilibrium warming – the natural greenhouse effect – was feedback response to the preindustrial noncondensing greenhouse gases.

It was that erroneous assumption that misled climatologists into assuming that feedback processes today would multiply the directly-forced warming from 1 K direct warming from doubled CO2 by about 4. For various reasons, including the points raised by Mr Langston, one cannot legitimately draw any such conclusion from the preindustrial record.

Sure enough, calculation based on the industrial-era record shows that we should only expect about 1 K equilibrium warming in response to doubled CO2: i.e., that in modern conditions one can ignore feedback response altogether and not introduce much error thereby.

Roy Langston
