Controversy over tropical ozone hole

Layers of Earth’s atmosphere

Have experts missed a huge tropical ozone hole that has existed since the 1980s? — asks Geographical. Or could it be more a question of definitions?
– – –
In July, an extraordinary research paper, documenting a huge, previously undetected ozone hole over the tropics, prompted a flurry of news stories.

Said to be seven times the size of the well-known ozone hole over Antarctica, the discovery is cause for ‘great global concern’, according to Qing-Bin Lu, a professor at the University of Waterloo, Canada, and author of the report.

His research suggests that, unlike the Antarctic hole, which only opens in spring, the tropical hole remains open year-round, putting roughly half the world’s population at higher risk from ultraviolet radiation.

Most surprisingly of all, Lu claims that the hole has existed since the 1980s.

Ned Nikolov & Karl Zeller: Exact Calculations of Climate Sensitivities Reveal the True Cause of Recent Warming

I’m delighted Ned Nikolov and Karl Zeller have chosen the Talkshop as the venue for the publication of this new open peer review paper on climate sensitivity. Scientific advance at the cutting edge has always been the most important aim of this blog, and I think this paper truly is an advance in our understanding of the climate system and the factors which support and modulate surface temperature on Earth and other rocky planets. 

The paper is mathematically rigorous, but is also accessible to everyone, thanks to Ned and Karl’s exemplary effort to fully explain their concepts and definitions in terms which can be understood by any interested reader who has some familiarity with the climate debate. Building on the bedrock of their 2014 and 2017 papers, this new work extends the applicability and validates the postulates of those previous papers by examining the causes of variability in planetary surface temperature and incorporating the previous findings in quantifying and deriving equations to model them. They find that Earth is sensitive to changes in cloud cover, which affects the amount of solar shortwave radiation reaching the surface, but not very sensitive to changes in Total Solar Irradiance arriving at the top of the atmosphere. They also find that the sensitivity to changes in CO₂ levels has been heavily overestimated by current climate models. They show that a doubling of atmospheric CO₂ concentration from 280 ppm to 560 ppm will cause an undetectable global warming of 0.004K.

Exact Formulas for Estimating the Equilibrium Climate Sensitivity of Rocky Planets & Moons to Total Solar Irradiance, Absorbed Shortwave Radiation, Planetary Albedo and Surface Atmospheric Pressure.
Ned Nikolov, Ph.D. and Karl Zeller, Ph.D.
April, 2022

1. Introduction

The term “Equilibrium Climate Sensitivity” (ECS) has become a synonym for the steady-state response of global surface temperature to a modeled long-wave radiative forcing caused by a doubling of atmospheric CO₂ concentration with respect to an assumed pre-industrial level of 280 ppm. According to climate models based on the Greenhouse theory, an increase of atmospheric CO₂ from 280 ppm to 560 ppm would produce a net radiative forcing (i.e. an atmospheric radiant-heat trapping) of 3.74 W m^-2 (Gregory et al. 2004) resulting in a global surface warming between 2.5 K and 4.0 K with a central estimate of 3.0 K according to IPCC AR6 (see p. 11 in Climate Change 2021: The Physical Science Basis. Summary for Policymakers). This implies an average unit ECS of 3.0/3.74 = 0.8 K / (W m^-2) with a range of 0.67 ≤ ECS ≤ 1.07 K / (W m^-2). Contemporary climate science and IPCC Assessment Reports do not discuss global temperature sensitivities to changes in cloud albedo, absorbed solar radiation or total surface atmospheric pressure. Consequently, no equations have been derived/proposed thus far to calculate these sensitivities. Part of the reason is that variations of cloud albedo are typically viewed in modern climate science as internal feedback to a climatic change induced by external forcing such as increasing anthropogenic carbon emissions. This notion is based on the 19^th-Century Greenhouse theory (Arrhenius 1896) adopted by IPCC, which attributes most of the observed warming during the 20^th Century and especially over the past 40 years to rising atmospheric  CO₂ concentrations believed to trap outgoing long-wave radiation in the Earth’s troposphere and reduce the rate of surface infrared cooling to Space.

However, a plethora of studies published during the past 15 years have shown through both satellite and surface observations that the absorption of solar radiation by the Earth-atmosphere system has increased significantly since 1982 due to a decreased cloud cover/albedo, a phenomenon often referred to as “global brightening” (e.g. Goode & Pallé 2007; Wild 2009; Herman et al. 2013; Stanhill et al. 2014; Hofer et al. 2017; Pfeifroth et al. 2018; Pokrovsky 2019;  Delgado-Bonal et al. 2020; Dübal & Vahrenholt 2021;  Yuan et al. 2021).

IPCC Climate Models Keep Failing Because They Don’t Respect Physics – The Daily Sceptic

By Dr. Rudolph Kalveks — As the media, politicians and climate activists continue to circulate hysterical hot air from the Cop26 conference, the topic of climate change or anthropogenic global warming (AGW) has become an emotional one, increasingly detached from the thoughtful and meticulous process of theory development, calculation and observation that is supposed to characterise scientific endeavour.

It may come as a surprise to some that “The Science”, as expounded in the IPCC Summaries for Policymakers that inform conference participants, is not uncritically accepted by all scientists in the field, and that widely different views are held by a substantial cadre of experienced and eminent researchers.

Moreover, a multitude of peer-reviewed papers contradict many aspects of the IPCC’s alarmist narrative.

Furthermore, a coherent theory about the impact of changes in greenhouse gases (GHGs) is starting to emerge, one that is built up from the underlying physics, rather than extracted from fanciful computer simulations.

My aim here is to highlight some of the relevant papers and to inform any motivated layman who wishes to explore outside the dogmatic strictures of the mainstream narrative.

Let us start with an irrefutable example of the inability of climate models (general circulation models, GCMs) to provide meaningful projections.

Doomberg: Where Stuff Comes From

Guest post from Doomberg. Original is posted at https://doomberg.substack.com/p/where-stuff-comes-from

“this dovetails in sinister fashion with the basic idea that any sufficiently advanced technology cannot be distinguished from magic. highly evolved capitalism becomes such a technology and the largess and plenty it produces gets mistaken for a property of the universe rather than a made thing, a thing that must be created rather than simply reaped.” – el gato malo

Modern society is awash in stuff. There’s stuff at the grocery store. At the hardware store. At Amazon and eBay. We eat stuff, wear stuff, buy stuff, and store stuff. Click some buttons, swipe a card, tap a phone – and presto! Stuff appears, like magic.

At least for now.

We are a carbon-based species. Carbon forms the foundation of our bodies and the external world we experience. Almost everything we touch is carbon-based. As I type this, I’m sitting on a couch made predominantly from foamed polyurethane, my feet resting on a carpet made from synthetic nylon. I just sipped water from a bottle made of polyethylene terephthalate, which I then placed on a coffee table made of wood.

Not only is our stuff mostly based on carbon, but the energy required to manipulate materials – to make stuff – comes predominately from carbon-based feedstocks as well. While not all stuff is based itself on carbon – copper wire is made of copper, after all – we can’t make use of it without first extracting energy from carbon fuels. In other words, we can’t mine copper without carbon. Those excavators, dump trucks, and bulldozers aren’t going to run themselves.

Since energy is life, mastering the chemistry of carbon and harnessing the energy of stuff to make other stuff is core to the human endeavor.

Science failed to predict flood and heat intensity, needs better computer – BBC

Weather forecasting technology

Maybe they need better ideas, not just more expensive modelling gear run by the same climate obsessives pushing worn-out theories that have never worked. Sales talk of ‘delivering the quantum leap’ sounds a bit thin after decades of posing as masters of climate understanding.
– – –
Top climate scientists have admitted they failed to predict the intensity of the German floods and the North American heat dome, says BBC News.

They’ve correctly warned over decades that a fast-warming climate would bring worse bursts of rain and more damaging heatwaves.

But they say their computers are not powerful enough to accurately project the severity of those extremes.

They want governments to spend big on a shared climate super-computer.

The Termination Event

.

Testable science ideas here. What’s not to like?

“What can I say?” laughs McIntosh. “We’re heretics!”

H/T g2

Spaceweather.com

June 10, 2021: Something big may be about to happen on the sun. “We call it the Termination Event,” says Scott McIntosh, a solar physicist at the National Center for Atmospheric Research (NCAR), “and it’s very, very close to happening.”

If you’ve never heard of the Termination Event, you’re not alone.  Many researchers have never heard of it either. It’s a relatively new idea in solar physics championed by McIntosh and colleague Bob Leamon of the University of Maryland – Baltimore County. According to the two scientists, vast bands of magnetism are drifting across the surface of the sun. When oppositely-charged bands collide at the equator, they annihilate (or “terminate”). There’s no explosion; this is magnetism, not anti-matter. Nevertheless, the Termination Event is a big deal. It can kickstart the next solar cycle into a higher gear.

As hydrogen is in the news these days as a potential ‘alternative’ fuel, heavily promoted by climate obsessives and others, this look back in history is vaguely topical and offers a fresh technical analysis based on experiments.
– – –
On the evening of May 6, 1937, the largest aircraft ever built by mankind, a towering example of technological prowess, slipped through the stormy skies of New Jersey and prepared to land, says TechXplore.

The airship Hindenburg was nearing the end of a three-day voyage across the Atlantic Ocean from Frankfurt, Germany. It was a spectacle and a news event.

Onlookers and news crews gathered to watch the 800-foot-long behemoth touch down.

And then, in one horrifying half minute, it was all over. Flames erupted from the airship’s skin, fed by the flammable hydrogen gas that kept it aloft, and consumed the entire structure, ending 36 lives.

Wilson of the Cloud Chamber – broadcast in 1959

Nobel prize-winning physicist CTR Wilson

‘Charles Thomson Rees Wilson, CH, FRS (14 February 1869 – 15 November 1959) was a Scottish physicist and meteorologist who won the Nobel Prize in Physics for his invention of the cloud chamber.
. . .
The invention of the cloud chamber was by far Wilson’s signature accomplishment, earning him the Nobel Prize for Physics in 1927. The Cavendish laboratory praised him for the creation of “a novel and striking method of investigating the properties of ionized gases”. The cloud chamber allowed huge experimental leaps forward in the study of subatomic particles and the field of particle physics, generally. Some have credited Wilson with making the study of particles possible at all.’ — Wikipedia.

Still waiting for greenhouse: No response to my last email to Roy Spencer

Before the last time I had to dive deeply into politics to defend the EU referendum result, I had an email conversation with Roy Spencer in an attempt to resolve the conflict between physicists like himself, who believe the radiative greenhouse theory is correct, but it’s effect small, and physicists like Ned Nikolov, who contend that the theory is fundamentally incorrect.

After a couple of to and fro emails I sent this response in Feb 2019, to which I never received a reply. It’s time we got this discussion back out in the open, because Boris’ green reset #netzero plan for the UK post Brexit and post pandemic is set to ruin our economy and cause untold suffering, deprivation, and death.

the lukewarmers have utterly failed to convince the fanatics that although they think their theory is correct (it isn’t, but that’s their misguided opinion), they’ve overestimated the magnitude of the effect.

It’s time they stopped supporting the fanatics by deploying false arguments against better theory which will exonerate CO2 and move the debate away from ridiculous and expensive ‘mitigation’, and forward to adaption to the effects of natural climatic change.

Chris Martz: No, global warming is not causing more frequent Arctic outbreaks

Credit: weather.com

By what known physics could a few molecules of carbon dioxide upset the jet stream? A meteorologist is not impressed by such claims.

By Chris Martz | November 9, 2019
INTRODUCTION Just when wildfires weren’t enough, we now have people blaming cold weather on a warming climate, which seems quite contradictory.

In light of the Arctic outbreak in forecast this coming week, people like Phil Plait (who has since blocked me) took to Twitter (Figure 1) to claim that man-made climate change is causing frigid, Arctic air to be displaced south into the United States, Europe, and Asia.

His argument, which is supported by some climate scientists, suggests that man-made global warming causes the polar jet stream to destabilize causing it to become wavy rather than zonal, sending Arctic air southward into the mid-latitude regions.

He also stated that without global warming, the polar air would stay near the north pole.

Both of these claims are exactly backwards from reality and are not supported by weather dynamics, the global warming theory, or statistical observations in long-term temperature data.

Record-Setting Noctilucent Clouds

.

Something of a mystery developing here. Open season for theories.

Spaceweather.com

June 11, 2019: On June 8th and 9th, many people who have never previously heard of “noctilucent clouds” (NLCs) found themselves eagerly taking pictures of them–from moving cars, through city lights, using cell phones and iPads. “I have never seen clouds like this before!” says Tucker Shannon, who took this picture from Corvallis, Oregon:

“I heard that they may have been seeded by meteoroids,” says Shannon.

That’s correct. NLCs are Earth’s highest clouds. Seeded by meteoroids, they float at the edge of space more than 80 km above the planet’s surface. The clouds are very cold and filled with tiny ice crystals. When sunbeams hit those crystals, they glow electric-blue.

Noctilucent clouds used to be a polar phenomenon. In recent years, however, researchers have noticed their electric-blue forms creeping south. Is it climate change? Or the solar cycle? No one knows for sure.

The physics of evaporation explained – pressure is the key factor

Not what some might have imagined perhaps. Researchers found that temperature difference between the surface and the liquid was less important than ‘the difference in pressure between the liquid surface and the ambient vapor’.

For the first time, MIT scientists have analyzed the evaporation process in detail at a molecular level and determined the physics of evaporation, reports Tech Explorist.

Evaporation is the process by which water changes from a liquid to a gas or vapor. The process is the primary path for water to move from the liquid state back to the water cycle as atmospheric water vapor.

Evaporation commonly occurs in everyday life. When you get out of the shower, the water on your body evaporates as you dry. If you leave a glass of water out, the water level will slowly decrease as the water evaporates.

For the first time, MIT scientists have analyzed the evaporation process in detail at a molecular level. For this, they used a new technique to control and detect temperatures at the surface of an evaporating liquid. Doing this, they were able to identify a set of universal characteristics involving time, pressure and temperature changes that determine the details of the evaporation process.

Earth’s mantle is magnetic, researchers find

Still plenty of work for scientists to do to gain a better understanding of our rotating Earth’s electromagnetic processes.

Scientists assumed Earth’s mantle, the layer stretching from the crust to a depth of 255 miles, was magnetically dead. New research suggests they were mistaken, reports Phys.org.

Most scientists thought Earth’s magnetism was powered by materials in the crust and core, but according to a new study published this week in the journal Nature, hematite, a common iron oxide, retains its magnetic qualities at high temperatures.

“This new knowledge about the Earth’s mantle and the strongly magnetic region in the western Pacific could throw new light on any observations of the Earth’s magnetic field,” Ilya Kupenko, mineral physicist and researcher from the University of Munster in Germany, said in a news release.

Polar Mesospheric Summer Echoes

.
.
Noctilucent clouds form when molecules from summertime water vapour stick to the microscopic debris of disintegrated meteoroids.

Spaceweather.com

May 21, 2019: Every summer since the late 1970s, radars probing Earth’s upper atmosphere have detected strong echoes from altitudes between 80 km and 90 km. The signals come from noctilucent clouds (NLCs).  NASA’s AIM spacecraft is still waiting to spot the first NLCS of the 2019 season, but the echoes have already begun. Rob Stammes of the Polarlightcenter in Lofoten, Norway, detected them on May 19th and 20th:

“I detected these VHF signals from Eastern Europe,” he explains. “They reflected from the mesosphere back down to my receiver in Norway. The wave patterns were recognizable and very strong.”

Researchers call them “Polar Mesospheric Summer Echoes” or “PMSEs.” They occur over the Arctic during the months of May through August, and over the Antarctic during the months of November through February. These are the same months that NLCs appear.

The underlying physics of these echoes is still uncertain.

Understanding physics could lead to big gains in shale oil recovery

A longer delay in the middle of an existing process could be the key to even greater success than is currently being achieved.

Oil companies are missing out on vast sums of recoverable oil in unconventional reservoirs, according to Penn State experts, as Phys.org reports.

The researchers propose that companies are applying tried-and-true transport mechanisms for conventional oil extraction but are hitting recovery stumbling blocks because they are not accounting for the difference in physics found at unconventional reservoirs.

Nikolov & Zeller: Reply to Dr Roy Spencer’s blog article.

Confusing Diabatic and Adiabatic Processes within the Climate Theory:

A Reply to Dr. Roy Spencer’s Blog Article “Giving Credit to Willis Eschenbach”

Ned Nikolov, Ph.D.
Physical Scientist

In a recent blog post, Dr. Roy Spencer at the University of Alabama at Huntsville attempted to criticize and dismiss the importance of our recent discovery about the physical nature of the atmospheric “Greenhouse effect” (Nikolov & Zeller 2017). I normally do not reply to blog articles, but this one reflects a fundamental generic confusion in the current climate theory that is worthwhile addressing for readership clarification. In his blog, Dr. Spencer demonstrated several misconceptions about our work that could be due to either not having read/understood our papers or perhaps an incomplete grasp of thermodynamics. The fact that Dr. Spencer cites a newspaper article about our research instead of the actual published paper may indicate a lack of familiarity with the technical details of our study. These are some key misrepresentations that I spotted in his article:    

1. Dr. Spencer incorrectly referred to our main finding as a “theory” when, in fact, it is a discovery based on vetted NASA data extracted from numerous published studies. This empirical pressure-temperature (P-T) function emerged from reported NASA measurements in the process of Dimensional Analysis, which is an objective technique employed in classical physics to derive/extract physically meaningful relationships from observed data.

Gavin Cawley explains the radiative greenhouse effect

Ned Nikolov, Ph.D.‏ @NikolovScience Oct 31

Here are 2 key issues that you must address when trying to defend the radiative “Greenhouse” hypothesis:

1. How does 240 W m-2 absorbed solar radiation get converted into 342 W m-2 IR back radiation without violating the Energy-Conservation Law?

2. Why there is such a POOR relationship between #CO2 and global T for past 70 My?

• Gavin Cawley‏ @Gavin_Cawley Oct 31

  Gavin Cawley Retweeted eli rabett

  The answer is still the same as the last time you ignored it

  Gavin Cawley added,

  

  eli rabett @EthonRaptor

  As Eli has pointed out many times, the 240 W/m2 is the solar input, not the energy the surface and the atmosphere exchange. 462 W/m2 enters the atm from the surface, 79 from the sun = 541 W/m2. 342…

  Ned Nikolov, Ph.D.‏ @NikolovScience Oct 31

  Gavin, this is not sensible answer to my 1st question, but a CIRCULAR argument! Can’t you see it? The 342 W m-2 IR back radiation cannot be explained by surface LW emissions, because then the question becomes, where does the 398 W m-2 surface LW radiation come from?

  Gavin Cawley‏ @Gavin_Cawley Oct 31

  I seem to remember I have already explained this to you at least once. Here is the thought experiment. Imaging a black body in a vacuum containing a 1W constant power heat source. Eventually it will reach an equilibrium temperature at which it radiates 1W out into the (1/n)
