Scope: This TWTW will focus on two additional, significant omissions, in the “Summary for Policymakers” of the Physical Science Basis of Sixth Assessment Report (AR6) by the UN’s Intergovernmental Panel on Climate Change (IPCC). The Summary for Policymakers (SPM) is used to justify drastic changes in the use of fossil fuels. Given the magnitude of such changes, the document should be of the highest scientific standards and demonstrate the scientific integrity of the IPCC.

Specifically, a presentation by Stephen McIntyre examining the extent of data, or lack thereof, covering the region of the Southern Hemisphere from 0° to 30° South Latitude will be discussed. Adding this to last week’s presentation covering the region from 30° to 60° South shows that there is very little data supporting IPCC AR6-SPM assertions that temperatures in this major portion of the globe have been roughly stable for the past 2000 years, until humans began emitting CO2 with the beginning of the industrial revolution, roughly 1850.

McIntyre has traced that the assertions that temperatures have been stable up to the industrial revolution come from a set of studies by an international paleoclimatology group based in Bern, Switzerland, known as PAGES 2k (PAst Global ChangES with 2k referring to the past 2000 years). This TWTW looks more deeply into this group and perhaps why it has such influence in the IPCC, particularly in that the work is not peer-reviewed, at least publicly, even though the IPCC claims the work it uses is peer-reviewed and publicly available.

Another significant omission in the SPM of AR6 is studies in spectroscopy, the study of the interaction between electromagnetic radiation and matter (mainly atoms and molecules). This is the direct study of the greenhouse effect, which the IPCC ignores. A study published on August 23 will be discussed.

Several other issues will be discussed such as Hurricane Ida which demonstrated success in public safety measures where it was a hurricane and failure in public safety measures where it was a tropical depression.


Lacking Data: Steve McIntyre has discussed the studies called PAGES, which are traced to a private international group called Past Global Changes based at the Main Building of the University of Bern, Switzerland. Using little supporting data, PAGES developed a 2000-year graph supposedly showing little variation in temperatures over time, yet with a significant upswing since the start of the Industrial Revolution. Roughly a new hockey stick lying horizontally with a sharp upswing in temperatures as the blade.

Previously, McIntyre’s study of the data sources covering the region from 30° to 60° South showed that there is very little data supporting a hockey-stick configuration. Focusing on the region from 0° to 30° South Latitude, McIntyre shows there are similar data deficiencies. Most of the data in PAGES studies do not support a hockey-stick configuration. For those familiar with the history of Mr. Mann’s hockey-stick McIntyre’s introduction is amusing. He writes:

“In a Climategate email. Keith Briffa famously sneered at Michael Mann’s claim that a temperature reconstruction could represent a hemisphere, including the tropics, by regressing a ‘few poorly temperature respresentative tropical series’ against ‘any other target series’ – even the trend of Mann’s own ‘self-opinionated verbiage’ as follows:

“’I am sick to death of Mann stating his reconstruction represents the tropical area just because it contains a few (poorly temperature representative) tropical series. He is just as capable of regressing these data again any other ‘target’ series, such as the increasing trend of self-opinionated verbage he has produced over the last few years, and …  (better say no more)’

“People frequently say that the PAGES2K reconstruction has ‘vindicated’ Mannian reconstructions – but neglect to mention that PAGES2K similarly regressed a ‘few poorly temperature representative tropical series’ onto an increasing trend – thus, repeating, rather than vindicating, (one of) Mann’s erroneous methodologies.

“In today’s article on the Hockey Stick featured in the new IPCC Hockey Stick diagram, I’ll look at proxies in the southern tropics (0-30S latband) [latitude band]. The proxy network turns out to be defective in bizarre, unexpected ways, not reported on or discussed in the original article.”

McIntyre then shows that PAGES has little data dating back 2000 years, and most of the data does not date back before the year 1500. Thus, the Medieval Warm Period is not covered. Over the past few years data from other sources have been accumulating that the Medieval Warm Period was a global event, not a regional event confined to Europe as IPCC advocates claim. McIntyre concludes:

“How the PAGES2K authors obtained a big-bladed Hockey Stick from this data cannot be determined without examining their code, which, to my knowledge, has not been archived. (Nor have it been provided to me upon tweet request.) My surmise is that they use some sort of ‘stepwise’ method in which successive steps incorporate the proxies available in that step. Such techniques will effectively splice the coral blade onto the two non-descript non-bladed long proxies to present a sort of hockey stick. The failure of the two long proxies to record the proposed blade means that the confidence levels prior to AD1800 or so extend from the ‘floor to the ceiling’ – an apt phrase used by Rosanne d’Arrigo many years ago. I.e. with this set of information, we know essentially nothing about 0-30S temperatures prior to AD1800 or so. This does not mean that we actually know nothing. There are many interesting proxies in the 0-30S latband and many fascinating discussions in technical literature that does not appear to be reflected in the IPCC report.

“Consolidating some of the information in this post with my prior post on the 30-60S latband, which consisted almost entirely (~96%) of ocean, PAGES2K only used one ocean core in the 0-60S latband, totally omitting high resolution alkenone series. Only four PAGES2019 series in the 0-60S latband start prior to AD1100 and none of them have a HS shape.

“Overall, I think that it’s fair to say that Briffa’s criticism of Mann remains just as appropriate for the IPCC in 2021, as it did in 2001. Like Mann’s network, PAGES 2019 ‘contains a few (poorly temperature representative) tropical series’. And PAGES 2019 authors ‘were just as capable [as Mann] of regressing these data against any other ‘target’ series, such as the increasing trend of self-opinionated verbage he has produced over the last few years’. Indeed, if anything, the new generation of climate activists have proved themselves more than capable of continuing Mann’s ‘trend of self-opinionated verbiage’ to, shall we say, ‘unprecedented’ levels. [Boldface added].

The new hockey-stick is featured in the IPCC’s AR6 Summary for Policymakers, without solid background support in the main document. As McIntyre shows both the tropical Southern Hemisphere from 0° to 30° South Latitude and temperate Southern Hemisphere from 30° to 60° South Latitude lack data supporting the new hockey-stick. There is no reason to accept the IPCC AR6 process and its reports as quality science fully backed by physical evidence. See links under Challenging the Orthodoxy and Defending the Orthodoxy.


What Are PAGES? The ability of PAGES graphs to suddenly appear in AR6 Summary for Policymakers, without clear explanation in the main body of the report, brings up the questions of what is PAGES, how does it get such graphs into AR6 Summary for Policymakers, and who funds it? Writing in No Tricks Zone, Pierre Gosselin translates and edits a German essay appearing in Die kalte Sonne by an unnamed scientist who is an IPCC 6th report reviewer. The essay begins:

“The latest UN report distorts climate history. The tracks lead to Bern, Switzerland.

In the Middle Ages, it was similarly warm in Switzerland and other parts of Central Europe as it is today. The so-called Medieval Warm Period (MWP) is scientifically well documented in the region: Between 800 and 1300 A.D., many Alpine glaciers shrank dramatically, and some were even shorter than today. The tree line shifted upward. Permafrost thawed in high alpine regions that are still firmly in the grip of ice today. Warm temperatures are also clearly evidenced by tree rings, pollen, chironomid fossils, and other geological reconstruction methods.

“Controversial temperature curve

It had long been assumed that the medieval warmth might be a regional, North Atlantic phenomenon. However, this has not been confirmed, because the warm phase also occurred in many other regions of the world, for example, on the Antarctic Peninsula, in the Andes, in North America, in the Arctic, in the Mediterranean, in East Africa, China and New Zealand.

“Peer-reviewed: Medieval Warm Period global

Together with professional colleagues, we at Die kalte Sonne have evaluated many hundreds of case studies from around the world in recent years and published the syntheses continent by continent in peer-reviewed journals.

Three of the publications have been cited by the Intergovernmental Panel on Climate Change (IPCC) in its recently published 6th Assessment of the Climate report. The medieval warmth was then followed globally by a precipitous drop in temperature. During the Little Ice Age, 1450-1850, the climate cooled to the coldest temperature level of the entire last ten thousand years.”

After a discussion of Mr. Mann’s hockey-stick in the Third Assessment Report (AR3, 2001) the essay continues:

“Recent paleoclimatological research confirms Medieval Warm Period

In the last two decades, however, paleoclimatology has made great progress, and data have been diligently collected. From this, more realistic temperature developments were created, with a pronounced Medieval Warm Period and a later Little Ice Age.

All the more bitter now is the relapse into old hockey stick times. How could this happen? What were possible motivations behind the renewed distortion of climate history?

“Why back to the hockey stick? PAGES 2k

The questionable new hockey stick temperature curve comes from the international paleoclimatology group PAGES 2k, whose coordinating office is based at the University of Bern in Switzerland. Climate scientist Thomas Stocker, who has contributed to IPCC reports since 1998, also teaches and conducts research at that university. In 2015, Stocker even ran for the overall IPCC chairmanship, but lost to South Korean Hoesung Lee, who just presented the 6th Working Group 1 report. Stocker co-authored the Summary for Policymakers of the IPCC’s 3rd Assessment of the Climate report in which the hockey stick played a prominent role.

“Dissent among the PAGES-2k group

A good twenty years later, the resurfaced field hockey stick now comes from Stocker’s university, where he heads the Department of Climate and Environmental Physics. Just a dumb coincidence? There are many indications that the new climate curve may have been a commissioned paper for the 6th IPCC report. Five of the nineteen authors of the papers on the new hockey stick curve are from Bern.

But a significant portion of the PAGES-2k researchers could not technically support the new hockey-stick version and walked out of the group in dispute.”

As discussed by McIntyre in previous posts, some members of PAGES did not go along with the latest hockey-stick. The essay continues with how this disgraceful process leads to misleading climate models used in AR6. The essay concludes:

“Political tactics undermining science

Thus, scientific integrity falls by the wayside. It is only a matter of time before critical climate scientists systematically address the inconsistencies in the filtered IPCC 6th climate report. The incident reveals how political tactics are undermining the IPCC’s scientific integrity and further eroding the trust placed in the institution.”

Gosselin adds:

“Climate researcher Thomas Stocker declined to comment when asked by WELTWOCHE. This article first appeared in WELTWOCHE Zurich: Die Weltwoche, No. 33 (2021) 19. August 2021. (Subheadings added by No Tricks Zone)”

According to the web site for PAGES:


PAGES facilitates activities that address past changes in the Earth System in a quantitative and process-oriented way in order to improve predictions of future climate and environment and inform strategies for sustainability.”

“Founded in 1991, PAGES was funded by the US and Swiss National Science Foundations until 2016. From 2017-2018, it was funded by the US National Science Foundation and the Swiss Academy of Sciences. From 2019, it is funded by the Swiss Academy of Sciences. It is supported in-kind by the University of Bern, Switzerland.”

A video on the PAGES website asserts a need for a full record of the past to understand the influence of CO2 on climate. The selective use of data and the lack of data are hardly a full record. See links under Challenging the Orthodoxy and Defending the Orthodoxy.


A Better Way? Since the publication of the Charney Report in 1979, the estimate of influence on global temperatures from doubling carbon dioxide remains at 3°C plus or minus 1.5°C. It has stagnated for forty years, since the beginning of space age instrumentation that can systematically measure what is occurring in the atmosphere. We can measure changes in temperature of atmosphere and changes in the greenhouse effect. Yet, the IPCC and its followers including NASA-GISS largely ignore what is being measured in the atmosphere.

Unfortunately, this is a characteristic of institutionalized science, it cannot accept change. Both relativity and quantum physics were strongly opposed by classical physicists. Even Einstein initially opposed quantum physics. But the data continue to compile, the earth is not warming as projected by the IPCC.

Western science journals have ignored other ways of estimating the influence of adding CO2 to the atmosphere. The IPCC knows best has been the chant. On August 23 a relatively new journal, the International Journal of Atmospheric and Oceanic Sciences, broke form and published a study displaying atmospheric data using the HITRAN database to estimate the extent to which doubling CO2 will increase global temperatures. The study extends to water vapor, methane (CH4), and nitrous oxide (N2O).

The results are similar to laboratory results from decades of experimentation in spectroscopy, the study of how electromagnetic radiation interacts with matter (mostly atoms and molecules). Although he did not understand it in the modern context, in 1859 John Tyndall used spectroscopy to study how certain gases (which he called greenhouse gases) slow the cooling of the land masses at night, preventing them from entering into a deep freeze, thus killing life as we generally know it. By far, the principal gas is water vapor.

The new study provides separate support that the principal greenhouse gas is water vapor. The abstract states:

“From this data it is concluded that H2O is responsible for 29.4K of the 33K warming, with CO2 contributing 3.3K and CH4 and N2O combined just 0.3K. Climate sensitivity to future increases in CO2 concentration is calculated to be 0.50K, including the positive feedback effects of H2O, while climate sensitivities to CH4 and N2O are almost undetectable at 0.06K and 0.08K respectively. This result strongly suggests that increasing levels of CO2 will not lead to significant changes in earth temperature and that increases in CH4 and N2O will have very little discernable impact.”

Of major interest to TWTW is the climate sensitivity of CO2 going from 200 parts per million volume (ppm) to 400 ppm, and from 400 ppm to 800 ppm. With the calculated feedback, the sensitivity is 0.46°C (0.8°F) for going from 200 to 400 ppm and 0.50°C (0.9°F) for going from 400 to 800 ppm. These are very similar to calculations by Wijngaarden and Happer, which are used by Howard Hayden as expressed in last week’s TWTW.

From the above, the real question is does it make sense to destroy the modern economy to prevent a warming humans cannot feel? Why do the IPCC and its followers insist that a warming from the beginning of the Industrial Revolution is from CO2 emissions when it is ever clearer it is largely natural variation? The journal has editors in China and India. Why should the leaders of these countries respect western governments which implore they stop using fossil fuels which have lifted so many from dire poverty? No doubt they will insist that the West show them how it is done. As stated in the conclusion:

“Feedback effects play a minor role in the warming of the earth. There is [not], and never can be, a tipping point. As the concentrations of greenhouse gases increase, the temperature sensitivity to those increases becomes smaller and smaller. The earth’s atmosphere is a near perfect example of a stable system. It is also possible to attribute the impact of the increase in CO2 concentrations from the pre-industrial levels of 280ppm to the current 420ppm to an increase in earth mean temperature of just 0.24 Kelvin, a figure entirely consistent with the calculated climate sensitivity of 0.50 Kelvin.”

The new study is not without issues. It is less comprehensive than prior studies by Wijngaarden and Happer. It does not contain details that describe the greenhouse effect and how it changes, including how greenhouse gases cool the atmosphere. For example, the greenhouse effect changes with altitude and latitude. Water freezes out at the tropopause, which changes with latitude and the seasons. In the polar winters there is little or no water vapor, thus the greenhouse effects there of the less important greenhouse gases.

Hurricane Ida: A great deal has been written in the mainstream media about Hurricane Ida, which intensified significantly as it came to the warm, surface waters near the shoreline of the Gulf of Mexico. After it hit as a category 4 hurricane, its intensity dissipated significantly. Thanks to learning lessons from Katrina, Federal and State agencies overwhelmed local environmental objections from green organizations, enforced by the courts, and built a system of moveable levees around New Orleans and some of the surrounding area which withstood the storm surge. Also, some local politicians who had been diverting federal funds meant for flood control and had been permitting substandard construction had been removed from office.

By contrast, it is disturbing to read so many drowned in New York and New Jersey in automobiles and, especially, in flooded basement apartments. Apparently, many basements were converted to apartments even though they do not provide evacuation safety, contrary to zoning laws. As with Katrina, some local politicians blamed others, especially climate change, to hide their incompetence. See links under Challenging the Orthodoxy for a good summary by Joe D’Aleo in ICECAP, Changing Weather, and Article #1.


Pogo-stick Power: For almost two months, TWTW followed the changes in wind power generation as reported by the Bonneville Power Administration (BPA), which includes the Columbia River Gorge “where the wind always blows.” The total nameplate generation is 27,879 MW of which 79.5% is hydro and 10.5% (2930 MW) is wind. [The balance is from other sources such as nuclear, gas, biomass, etc.]

This week provided a clear example of the deficiencies of wind power. It reached a high of 2500 MW late evening on August 30, fell to 1500 MW by midday on Aug 31, bounced up a bit before falling below 500 MW by midnight. From early morning September 1 to late day September 4, it has been below 500 MW, largely between 200 MW and Zero MW. Such power generation cannot replenish utility-scale storage in a timely manner, whether it is pumped hydro or non-existent batteries. See links under Energy Issues – US.

Number of the Week: A 30-foot (9-meter) bank: According a description in the New England Historical Society of the great 1938 hurricane which hit Long Island on September 21.

“At 12:30 PM, a 30-foot bank of what looked like fog rolled in toward Long Island. It turned out to be the storm surge, topped by waves 30 and 50 feet high.

“By 4 pm, one of the most powerful and destructive hurricanes ever to hit Southern New England made landfall between Bridgeport and New Haven, Conn.

“The damage was horrific. Estimates vary, but at least 400 people died that day and maybe as many as 800. The Great 1938 Hurricane crossed over the tip of Long Island, slammed into New London, and raced up the Connecticut River Valley at 50 miles per hour. It destroyed cemeteries, slammed boats into shore, uprooted entire orchards and smashed structures into splinters.”

“A total of 4,500 homes were destroyed and 25,000 damaged. The storm totaled about 26,000 automobiles and blew over 20,000 electrical poles. And high winds knocked down an estimated 2 billion trees in New York and New England, devastating forests.”

“Readers will probably be disappointed that there is no simple solution to a deep cultural problem that has overtaken large segments of the scientific community. Eventually, perhaps decades in the future, scientific truth will prevail. Especially as members of the public learn to dig into the data for themselves and not to place uncritical faith in what they are told ‘the science’ says, even when the message is coming from scientific institutions we were once able to trust.”

“The real question is why, if the planet is warming relentlessly and the ice is melting, the ice isn’t melting. To quote the U.S. National Snow & Ice Data Center’s August 18 newsletter, ‘The Northern Sea Route appears closed off in 2021, despite being open each summer since 2008.’”

“Claiming magical powers for ‘peer review’ is not by any means the dirtiest trick in the alarmists’ bag.

Real sciences are increasingly looking into the problems of replication and peer review. Time for climate science to do it too.”

1. Hurricane Ida’s Climate Resilience Lesson

Spending to protect against extreme weather beats green boondoggles.

By The Editorial Board, WSJ, Aug. 30, 2021

TWTW Summary: The editorial begins:

“The pictures of Hurricane Ida’s wreckage across Louisiana are grim, and the storm isn’t over. But the good news is that New Orleans appears to have weathered the tempest as well as could be expected thanks to its post-Katrina flood-protection investments. This is a reminder of how hardening infrastructure against unpredictable Mother Nature pays off.

“Ida slammed into Louisiana’s Port Fourchon on Sunday as a Category 4 storm with wind speeds of 150 miles an hour and one to two inches of rain an hour. Its winds tie it as the fifth strongest storm to hit the U.S. mainland. Such heavy winds and precipitation will inevitably cause flooding and damage buildings.

“But the bigger worry going into Ida was that a catastrophic storm surge would breach New Orleans’s levees and submerge the city as happened 16 years ago to the day during Hurricane Katrina. Clocking in as a lower-grade Category 3 storm when it made landfall, Katrina killed some 2,000 people and caused an estimated $125 billion in damage. New Orleans took years to recover.

“Yet Louisiana and the feds have since spent $14.5 billion on bolstering flood walls, levees and drainage systems. The U.S. Army Corps of Engineers reinforced pumping stations to withstand 205 mile-per-hour winds and established redundant power systems to operate them if the electric grid fails, as it did Sunday.

“These investments appear to have paid off. Many streets are flooded from the heavy rainfall and some small towns outside of New Orleans’s flood-protection fortress were inundated. But more important, a Southeast Louisiana Flood Protection Authority spokesperson on Monday said there were no levee breaches or problems with pumps in New Orleans.

“The biggest failure was the electric grid. Eight transmission lines that serve the city went down and a grid imbalance caused a loss of power generation across the region, cutting off power to nearly one million Louisianans. Essential businesses like hospitals can run on backup generators, but it could take weeks to restore power in some neighborhoods.

“There’s probably a case for burying some power lines and girding substations to withstand more powerful storms, as Florida Power & Light Company is doing in Florida neighborhoods that have experienced damage to power lines in past storms. Hardening the grid to withstand extreme weather isn’t cheap, but the payoff is likely worth it.

“As predictable as the sunrise, the climate lobby is blaming humanity’s fossil-fuel sins for Ida. But even the United Nation’s Intergovernmental Panel on Climate Change report this month notes “there is low confidence in long-term (multi-decadal to centennial) trends in the frequency of all-category tropical cyclone” (i.e., hurricanes).

“The report says that it is likely that the global proportion of Category 3 or higher tropical cyclones has increased over the past four decades, but that “data limitations inhibit clear detection of past trends on the global scale.” In short, we don’t really know whether global warming has caused or will cause more intense storms in the future.

“But no matter how much the world warms, more extreme weather will happen. Building more resilient infrastructure and better emergency alert systems will do far more good than all of the Biden Administration’s climate policies. Germany has spent hundreds of billions subsidizing green energy, but nearly 200 of its citizens perished in last month’s floods that local governments failed to prepare for.

“Priorities also matter so scarce resources aren’t wasted. Too much of the Senate’s infrastructure bill is devoted to green boondoggles, rather than resilience.”

After a discussion of California’s wildfires the editorial concludes:

“Government can’t command the tides, but it can protect people from them.”

Only rapid and drastic reductions in greenhouse gases in this decade can prevent such climate breakdown, with every fraction of a degree of further heating likely to compound the accelerating effects, according to the International Panel on Climate Change, the world’s leading authority on climate science.

Meteorological bodies have referred to the rainstorm in China – which saw a year’s worth of rainfall in three days – as a one-in-1,000-year weather event. The rainfall broke hourly and daily records of the 70 years of collected data.

The heavy rainfall in the south of North Rhine-Westphalia and north of Rhineland-Palatinate in Germany produced accumulations which averaged 100 to 150 mm (3.9 to 5.9 in) in 24 hours, equivalent to more than a month’s worth of rain. In Reifferscheid, 207 mm (8.1 in) fell within a nine-hour period while Cologne observed 154 mm (6.1 in) in 24 hours. Some of the affected regions may not have seen rainfall of this magnitude in the last 1,000 years.

The searing heat that scorched western Canada and the US at the end of June was “virtually impossible” without climate change, say scientists. In their study, the team of researchers says that the deadly heatwave was a one-in-a-1,000-year event.

The rain in New York was just another climate related extreme weather event.

And we have 4 other US heatwaves, one in E Europe and Russia, a temperature record heatwave in Lapland, in N Finland, record breaking temperatures in Siberia for second year running, record breaking temperatures in Greece, extreme temperatures in Turkey, Iran, S China…

So many extreme weather events, many in northern areas, four of them 1,000 year events in last few months – AND STILL THERE’S NO CLIMATE CHANGE IMPACT YOU SAY?

Every day, high temperature records are set in some locations and every day, low temperature records are set in some locations. Every day wind speed records are set in some locations.

How about some plausible statistics for a change? Pointing at bad weather and claiming climate change is at fault is really really lame. Bad weather has always happened and always will happen. The actual evidence is that bad weather was more prevalent during the Little Ice Age. link

WUWT needs to embargo all griff comments until there are at least 10 comments on an article. griff has an app which notifies them when new articles are posted, so they can jump in right away. Responses to their comments then further clutter up the initial comments.

Maybe one of the editors could email griff and tell them that any of their comments among the top 10 will be deleted. Give the choice of self-policing as an option and then start deleting if there isn’t voluntary compliance.

And the State of Michigan, with a land area only a little smaller than New Zealand (if you count all 700 or so islands of the latter) had an unusually cool summer. We had one hot week in June, one in July, and one in August. Otherwise, we struggled to reach 80F most of the time, when temperatures that high are normal through most of July and all of August. We were wearing flannel pajamas and using heaters in early July. What’s your point?

Difficult to comment on this very large collection of items … Heartland NIPCC analysis / report is 2013 vintage… it didn’t have any effect back then and won’t have any effect now. Suggest maybe focus on today – how we can counter the misinformation and propaganda and manipulation being put out now… I would like to see a major analysis / study on why climate change has to be a movement at all … one reason is it’s very very political … b.t.w. how many university departments (and budgets) and research programs and professors have benefited from / resulted from the “climate change movement..” Every university today has a department of climate change with scores of professors and support staff… add it up across the globe … the dollar value makes “climate change” likely rank in the top 20 re country GDP in dollar value… are you surprised? A massive incentive to jump on the wagon and push the climate change narrative !!!.

September 6, 2021 9:07 am

Regrettably the article in “International Journal of Atmospheric and Oceanic Sciences” is complete garbage (link below). What they did is to introduce a term “n” to convert the amount of radiation absorbed by GHGs into their GHE. They assume GHGs would absorb 73% of 390W/m2 surface emissions, meaning 284.7W/m2. Then they assume a GHE of 150W/m2, and so n = 150/284.7 = 0.527

Next they conclude CO2 would only add 5.6% (of 390W/m2) to the absorbtion of surface radiation, and thus would only provide 5.6% x 0.527 = 3% of 390, or 11.7W/m2 to the GHE of 150W/m?! And since 11.7/150 (or 3/38.5) x 33K = 3.3K (sic!), they get to their findings..

comment image

Needless to say there is no linear relation between radiation absorbed, and GHE, as the latter depends on emission altitude, not how much surface emission were absorbed at the bottom. Equally they provide no reason as to why the overlapped CO2/vapor band should be attributed only to vapor. And so on..

But hey, why should WUWT bother with propor science, when you can feature such junk? The other ironic part is, that a figure of 0.5K for doubling CO2 is fairly accurate, though for all the wrong reasons.
