Forty percent of Antarctica’s ice shelves are shrinking, worrying scientists by Kasha Patel, Environment, Washington Post, Oct 12, 2023

American society wasn’t always so car-centric. Our future doesn’t have to be, either

nigelj is correct that 'modern city building' has most unfortunately been based on 'car culture'. That has put all those 'car fuelled developments' at a competitive disadvantage. Owning and operating a car is a significant cost (a pick-up truck is even costlier) that is not suffered by people living in a '15 minute city'.

The concept referred to as the '15 minute city' does not require personal vehicle ownership. NPR's Climate Week included the following article about the 15 minute city concept: "It's a global climate solution — if it can get past conspiracy theories and NIMBYs". It also presented the following similar article as part of its Climate set of articles: "The '15-minute city' could limit global warming — if it can counter misinformation"

The absurdity of claims made about the pursuit of '15 minute city' redevelopment by people fighting against learning to be less harmful and more helpful would be amusing if they were not so absurdly popular. And it is particularly nasty that some of the arguments against the helpful harm reducing redevelopment are fuelled by the desire of people in 'isolated un-diverse suburbs' to 'not have those other types - the poorer people - living among them'.

CO2 limits will harm the economy

PollutionMonster @117,

As a Professional Engineer with an MBA who is interested in ‘actually sustainable’ human development, particularly the sustainable improvement of living conditions for everyone who suffers a less than a basic decent life, I agree with your concerns. But solving the climate change problem is more complex.

Carbon pricing, cap and trade (and related carbon offsets) are potentially helpful actions within the currently developed socioeconomic political systems. Those measures can motivate people be less harmful. But note that Carbon Fees are harder to evade or manipulate than Cap and Trade or carbon offsets. Also rebating Carbon Fees can be helpful, more helpful if more rebate goes to lower income people (no rebate to high income people).

There is plenty of evidence to justify concerns about individuals or organizations (like companies or political groups) trying to benefits by being more harmful and less helpful because that is often easier and cheaper. ‘Pursuit of self interest’ can motivate people to evade or fight against things like fees, fines, restrictions, or programs paid for by taxes that are related to getting people to be less harmful or more helpful. That evasion and fighting includes unjustified demands for more freedom to believe and do as they please.

Also, it is important to understand that the required objective is ending the accumulation of global climate change impacts (and reducing the likely excessive harm done by delayed reduction of unnecessary harm by the most fortunate), not just reducing the rate that it is happening. And, ethically, that objective has to be achieved while sustainably improving the living conditions for all of the less fortunate people. A major challenge to achieving that objective is getting all of the people who enjoy better than basic decent lives to help end the harmful unnecessary activities they enjoy benefiting from.

Carbon pricing measures may not achieve the required result of altering the actions of all of the most harmful people, even if the price is very high. Some of the most harmful higher status people will delay the required correction by abusing misinformation to gain support for their fight against costs and restrictions on harmful things they benefit from. In addition, the most fortunate will be able to pay the higher price and claim that that justifies their continuing to be unnecessarily harmful.

A nasty complexity of Carbon Pricing is the many ways that it can negatively impact people who need assistance to sustainably develop to live basic decent lives. And richer people will fight against paying more to help those who need assistance. They try to evade changing by complaining that measures to end climate change impacts will hurt the poor. What they do not admit is that the more fortunate need to do more to help the least fortunate sustainably develop basic decent livings while the more fortunate give up benefiting from more damaging, but cheaper and easier, ways to unnecessarily obtain more benefits.

This is an age-old systemic problem. And Matthew Stewart presents it well in "The 9.9 Percent". His evidence-based book (loads of references) explains how the most powerful 0.1% unjustifiably win with harmful unjustified support from the rest of the top 10% (the 9.9%), and are excused by a portion of the remaining 90% that divisively fights with misunderstanding trying to become 'higher-status' like the top 10%. It is a developed systemic problem. In a nut-shell the required corrections compromise the ability of the undeserving among the top 0.1 Percent (in wealth and power) to be supported and excused by the rest of the top 10% or any of the 90%. Note: 0.1% of the current global population is 8 million. And 10% is 800 million. Essentially every nation, corporation, and political group is influenced by undeserving trouble-makers.

So, it is justified to be concerned about ‘harmful cheaters’. However, a key challenge is increased awareness and understanding of the magnitudes of harmful influence. All people, companies, political groups, or nations are not equally harmful or helpful. And they can all change to be less harmful and more helpful (note that people who are less fortunate can be excused for being more harmful and less helpful). The important difference is how hard people, and the organizations they are part of, try to be less harmful and more helpful. More fortunate people who fight hardest against the undeniable required corrections need to be the focus of concern.

American society wasn’t always so car-centric. Our future doesn’t have to be, either

Our cities have mostly been designed around the automobile. I agree that its not inevitable that we base our transport system on the automobile, but we have thus far and the end result is we have desined cities with certain activities zoned and grouped together for practical reasons, and so we typically live in suburbs quite long distances from our places of work, the shops, the entertainment, the farms.We have become frighteningly reliant on automobiles, trucks and buses etc,etc to make this system work.

It seems unlikely to me that we can keep this system going indefinitely at large scale because of the pollution and load it puts on the earths resource base. Its just not very sustainable. Evs are an improvement on ICE cars but dont solve all the problems.

The walkable city concept has been proposed as a solution( easily googled but one source below) .

en.wikipedia.org/wiki/15-minute_city

I've heard this expressed as everyhting should ideally be within comfortable walking or cycling distance, so your place of work, the shops, the doctors and dentists, ideally even the farms. This means you dont need a car unless you have special needs. We would presumably still need some cars for emergency services, travel between cities etc,etc and during the transition phase to walkable cities - and better that they are EV's.

And I can see the walkable city working for office workers but it would be more challenging to deal with industry. Although China have designed entire new industrial cities so that housing is grouped quite close to the places of work within cycling distance.

And there is the issue of our food sources. Do we continue to live in large centralised cities remote from our food sources? Or should we move back to a small town model where everyone can walk or cycle to the farms?

Most existing cities are designed around the car and assuming we stay living within these cities, physically changing them to make them even partly walkable cities will clearly be a big undertaking. But we have to start somewhere, because its not plausible for billions of cars to be made and this continued indefinitely, and walkable cities have multiple benefits.

The question is whether we are proactive and push things slowly towards a walkable city (of some sort), or we do nothing and wait until scarcity of materials forces a collapse of our transport system and makes the transition to a walkable city urgent and more painful to achieve. I hope for the former, but my cynical side thinks the later.

CO2 limits will harm the economy

I had some concerns about a cap and trade program and carbon tax. Is this simply a form of greenwashing or will this actually work?

I worry that companies which already find lots of ways to avoid fines and taxes will just find loopholes. I might be being paranoid, but what's to stop a company from just transfering all their fines to a victim corporation via leveraged buyout, saddeling the corporation with debt and selling all the assets? Like what is already happening with private equity firms.

I feel carbon pricing is a system designed to be abused and is greenwashing when we could focus on more effective means like simply shutting down all coal plants and making the switch to electric cars. Is a carbon price just another form of greenwashing similar to carbon capture and storage?

At a glance - Climate scientists would make more money in other careers

My organisation funds a wide variety of scientists (including many related to sustainability & environment), so we cross check FTE rates carefully as people costs are often the largest prject expense. I can confirm that scientists employed in the public arena (universities etc) are not that well paid - working for commercial and private organisations often pays a lot more. And working for fossil fuel, tobacco companies etc pays best of all (for obvious reasons). Ridiculous to think that climate scientists work just for money, especially given the constant hate mail and controversy that they receive.

At a glance - How do human CO2 emissions compare to natural CO2 emissions?

amhartley @ 4:

You've had a few answers that might help. I'll add the following.

You mention "thickness of the atmosphere". When discussing radiation transfer (absorption in this case), it is not the physical distance that matters. It is the number of molecules of the absorbing gas that affects the probability of radiation absorption. You can pack the same number of molecules into a short physical distance, or spread them over a larger distance, and the absorption characteristics will remain the same. In radiation transfer, you will see the term "optical thickness" or "optical depth". to distinguish this from physical distance.

This post on Beer's Law gives an illustration of this.

...but yes, IR radiation emitted at low altitudes will be unlikely to reach space directly. But at each level, the atmosphere also emits IR radiation, and the further up you go, the more likely it is to reach space directly. Understanding the greenhouse effect writ large requires looking at both absorption and emission, and at all levels.

There is more discussion of this on the Beer's Law post I linked to above, but a useful resource online is MODTRAN. You can play around there with a full atmospheric IR radiation transfer model that includes all these effects.

At a glance - How do human CO2 emissions compare to natural CO2 emissions?

A single photon of IR of right wavelength leaving earths surface doesnt travel very far at all. I think mean path length before absorption is less than 10m at 400ppm (too lazy to calculate). As the Dessler video shows, what matters is the height where IR can escape to space.
I am fond of Chris Colose explanation.

Rob Honeycutt at 12:24 PM on 2 October 2023

At a glance - How do human CO2 emissions compare to natural CO2 emissions?

amhartley... What you stating isn't a good explanation of how the greenhouse effect works. Andrew Dessler has a good explanation here.

Essentially, the GHE functions due to the effective IR emission altitude. Adding greenhouse gases causing that emission altitude to rise and the thermal gradient determines the temperature rise at the surface.

amhartley at 12:15 PM on 2 October 2023

At a glance - How do human CO2 emissions compare to natural CO2 emissions?

I'm a statistician, not a natural scientist, so I cannot say it matters, but I wonder whether we should call attention to the thickness of the atmosphere &, in particular, of the troposphere (bottom 8 to 14 km of atmosphere). Given that thickness, an IR ray passing upwards thru CO2, CH4, & other GHGS at even very low (but increasing) concentrations would have diminishing chances of escaping to outer space. Is that a valid argument?

Markp lost any remaining credibility when he started comment 51 with "IPCC apologists".

From wiktionary:

apologist(plural apologists)
1. One who makes an apology.
2. One who speaks or writes in defense of a faith, a cause, or an institution

Markp's choice of nouns leaves the impression that he thinks of people that disagree with him as defending a faith or a cause. He'll probably say that he meant the third version - defending an institution - but the dog-whistle of "apologist" (rather than other possible choices, such as "defender") tells us more about him than it tells us about his opponents in the discussion.

Bob Loblaw at 22:51 PM on 30 September 2023

2nd law of thermodynamics contradicts greenhouse theory

Yes, the "explanations" that Likeitwarm prefers are indeed "the most screamingly laughable, unphysical explanations".

In comment 1606, Likeitwarm brings us back to the laughable paper by Peter Ward. Likeitwarm says:

Your radiated photons from all emitting gases carry wave length and amplitude dependent on temperature emitted from.

This repeats the laughable statements from Peter Ward, that attribute "amplitude" as a characteristic of radiation. Radiation does not have "amplitude". It has been over 100 years since physics addressed the issue of particle-wave duality in radiation. Radiation has attributes that can be described or explained by treating it as a particle, and radiation has attributes that can be described or explained by treating it as a wave - but in none of those scenarios does "amplitude" show up.

When Planck's Law calculates more energy at a specific wavelength or frequency from hotter objects, the increased energy comes from more photons, not higher amplitudes of waves. Every single photon that ever existed at a specific wavelength had exactly the same energy, regardless of when, where, or at what temperature the emission occurred. Any talk about "cold" and "hot" photons of the same wavelength is crank physics.

The "explanations" that Likeitwarm prefers are not simply "CO2 causes climate change science" denial, or even "climate science" denial - they are basic physics denial.

"I'm just looking for the most plausible reasons for climate change""

And yet you somehow pick on the most screaming laughable, unphysical explanations because they suit your preference. You cant just cherry pick bits of physics to back up an explanation. All the laws of physics apply, apply the time. Frankly no one like the idea that we have to stop to emitting GHG but scientists are too honest to ignore it. Invoking "reflecting photons" and other fairie dust doesnt cut it.

Likeitwarm... "The surface is warmer, not from the GHE, but from gravity doing work on the atmosphere causing adiabatic heating."

If this was true, how do you get these shifts in the thermal gradient of the atmosphere? Inquiring minds want to know if you think gravitity is fluctuating through the vertical profile.

michael sweet at 09:45 AM on 30 September 2023

2nd law of thermodynamics contradicts greenhouse theory

Likeitwarm, I usually don't comment on the thermodynamic thread, but you have it completely backward. Scientists have never argued that CO2 causes warming because they measured warming and then said CO2 was the cause.

In fact, scientists measured the IR absorbtion spectrum of CO2 (in 1850) and then predicted in advance that increasing CO2 would cause the atmosphere to increase in temperature. Your claim that "All you have is a correlation that doesn't prove anything." is false. Scientists predicted 150 years in advance that increasing CO2 would cause the atmosphere to heat up.

A prediction in advance that is correct is very strong evidence in support of a theory. Can you provide an example of a prediction that your data sourse has made that was correct???

Rob Honeycutt at 05:31 AM on 30 September 2023

This is quite obviously untrue because clearly the most plausible reasons for climate change come from the overwhelming body of research demonstrating that CO2 is the primary cause.

I think you just don't like that conclusion and are cherry picking your way into "alternative facts," as they say.

Your link to the extract from Wim Carton's 2020 book is not (IMHO) particularly useful. Carton supplies many paragraphs of general discussion ~ mainly equal parts vagueness and bloviation.

2020 may have been a bit early for ChatGPT as a co-author. Then again, Carton may have been an early adopter, and was contracted for a 100,000 word book. Yes I am being a bit harsh : but a book with extensive sociological commentary is always in great danger of being vague and so all-inclusive that it ends up failing to produce a clear message ~ it can be Bible-like, in that you (the reader) can find & select almost anything your heart desires from it.

2nd law of thermodynamics contradicts greenhouse theory

1600. Rob Honeycutt et al
I'll wear that name proudly!
I'm just looking for the most plausible reasons for climate change.
I have found a number of theories. You will call them all quackery because they are not your theory.

I like Peter Ward's. Scroll down the page you sent me and read Peter's responses to his challengers. He makes a lot of sense. His challengers did not prove him wrong, only disagreed with him.
What I find wrong with your version of the science is that you say the small amount(less than 8% of all IR from the surface) re-radiated IR from a colder part of the atmosphere causes warming of the surface per Trenberth chart. That cannot happen. Your radiated photons from all emitting gases carry wave length and amplitude dependent on temperature emitted from. Not enough energy to heat the surface there. Per Ward 2015 colder IR is reflected by warmer object, not destroyed.
Magically, your chart shows the down welling radiation is greater, almost double, than what the sun supplies. Satellites see 255k for the temperature that is radiated from about 5-6 km altitude, not from the surface. The surface is warmer, not from the GHE, but from gravity doing work on the atmosphere causing adiabatic heating. This is why near surface temperatures are ~33c warmer than Planck equations predict. That makes sense unlike the GHE raising the temperature that much.
There is no experiment showing co2 warms the atmosphere.
There is no measurement showing human emissions of co2 cause the recent warming.
All you have is a correlation that doesn't prove anything.
The extra UV-B radiation reaching the surface warms the ocean and the warmer ocean emits more co2 per Ward 2015 makes sense and he does have a correlation with ozone levels and temperatures. Read his paper I linked to.

I know you like labels, but get the label right.
It's "CO2 causes climate change science denier" not "climate science denier".

Markp... Who do you think should be taking action on climate change and how do you think they should endeavor to do it?

I would note that, somehow, I guess inconceivably, government-led action is how we ultimately solved the crisis related to emissions of CFC's.

Mark, you might also want to note the IPCC doesn't have any power to regulate anything, nor can they implement any solutions. They are merely the intergovermental body that communicates the science, risks and impacts we face.

It's the UNFCCC at the COP conferences where goverments meet in attempts to create agreements that would address the problem. And those agreements are non-binding agreements between nations. The Paris Agreement was a product of the UNFCCC.

What is not clear in your post is, what do you think William Carton is saying?

I think you're on to something, Eclectic. That's pretty much what it would take to overturn our modern understanding of the GHE and climate change. It would require a complete restructuring of physics as we understand it today.

It's certainly a possibility that Dr. Ward is the person who accomplishes this feat. An infinitessimally small possibility, but still a possibility none-the-less. And if that should come to pass, we will all recognize Likeithot for his keen insight and can re-embark on burning FF's with reckless abandon.

Dr Ward's novel ideas are certainly intriguing, and may be introducing us to concepts that go completely beyond Quantum Mechanics. In physics, they could represent a great leap forward (to borrow from the political terminology). Or a quantum leap (to use the vernacular term). What a time to be alive!

The commenter Likeitwarm may be on the cusp of understanding how these advanced ideas are producing a fusion ~ a fusion of Denialati and Illuminati. Truly a new Enlightenment.

Perhaps this new development will give Likeitwarm encouragement and . . . a quantum of solace?

MA Rodger at 05:49 AM on 29 September 2023

2nd law of thermodynamics contradicts greenhouse theory

I was intrigued by the Ward (2016) quote made by Likeitwarm @1590.

"It is the frequencies and amplitudes of these radiating oscillations that, when absorbed by cooler matter, increase the amplitudes and frequencies of the internal oscillations of the absorbing matter, thereby increasing the absorbing matter’s temperature. It is these frequencies and amplitudes that appear to be reflected, rather than absorbed, by warmer matter [22]. When radiation has lower amplitudes of oscillation at each frequency than the prevailing amplitudes of oscillation within receiving matter, heat cannot flow into the matter by resonance, cooler to hotter. Therefore, by conservation of energy, “colder” radiation must be reflected."

How do you measure the 'temperature' of a photon to know that it is "colder"? We have no actual knowledge of what a photon is, just its impact on the universe it is emitted from and absorbed/reflected/refracted by. And that shows us the energy of a photon (so presumably some marker of its 'temperature') is solely a function of its wavelength. There is no variation in any 'amplitude'. So all this guff from Ward about radiation having both 'frequency' and 'amplitude' is a fantasy.

The reference [22] which Ward uses three times to support the same crackpot contention refers to Evans & Popp (1985) 'Pictet's experiment: the apparent radiation and reflection of cold', an account of a certain Marc-Auguste Pictet's 1784 experiment along with Evans & Popp's explanation of how the 'reflection of cold' was actually measuring a drop in temperature when the "relatively high-temperature radiation** is replaced ... the thermometer now recieves less energy per unit time than previously." [**That is radiation emitted from a relatively warmer source.]

The difference here is this: Given enough evidence and strong research, any of us could be convinced there is something other than CO2 responsible for warming the planet in the modern era. You, on the other hand, will never accept the overwhelmingly research that currently exists regardless of how convincing it is.

Being truly skeptical means being convincible. Thus, I would term you a climate science denier. And that is the very premise of how this website was named.

Ah, yes. Likeitwarm brings out the strawmen of "AGW theory", "where's your proof?", etc. And now, he's using Friends of Science as a source. As Eclectic says, these sources are simply delusional about the science.

The last link provided by Likeitwarm is a paper published in Energy and Environment. As quoted on this Desmog page about the journal, E&E is "a journal that climate change deniers go to when their papers have been rejected by mainstream peer-reviewed publications."

The holes in the papers Likeitwarm has linked to are so large you could drive a Mack truck through them. They have been debunked many, many times in the past.

As for Likeitwarm's posting history here at SkS, he has pretended to have an open mind about the science, but his last couple of posts have made it clear that he has participated here with his mind made up, and that he only accepts information that fits his desired conclusion.

Look inside yourself and ask why you choose to cherrypick these disproven ideas originating from a few - a very small handful - of "contrarian scientists". That is the question for you . . . if you are brave enough to face yourself in the mirror.

Let me hasten to add : AFAIK the good Dr Miskolczi may well be a nice guy and kind to children & animals. And AFAIK, lawyers would not consider him legally insane . . . but he is delusional about this area of climate physics.

Sadly, Likeitwarm, there's a small number of scientists who are simply delusional. It's a quirk of their personality, a crazy streak. But that is no reason for you to be sucked in by them.

Oh, my Jennifer Marohasy is a completely unreliable source. The article it links to starts with this paragraph (leaving the grammatical errors intact):

Central to the theory of Anthropogenic Global Warming (AGW) is the assumption that the Earth and every one of its subsystems behaviors as if they were blackbodies, that is their “emissivity” potential is calculated as 1.0.

This is absolutely, completely wrong. No such assumption is made. The reference provide is to a book (?) about "slaying the sky dragon". The Sky Dragon believers are about as nutty as it gets.

You then post links to principia-scientific.com, which has strong ties to the Sky Dragon believers and is about as reliable as the Flat Earth Society.. It is a collection of deniers - not a useful source of anything remotely scientific. You can read more about the organization here.

You then delve into the standard "it's a plot" that characterizes the conspiratorial thinking that saturates the common denier mentality.

You claim to "...find a lot, 1000s or more, of scientists that disagree with AGW." But what you are presenting here is just more of long-debunked crap.

So even the relatively slow increase you note of 1 ppm/year during the early years following the Industrial Revolution were, in geological terms, extremely rapid.

Eclectic @5,

I agree that there is a preponderance of reporting of incorrect evaluations of ‘development progress’. Your example of a lack of improvement that could incorrectly be counted as an improvement is a god one. I would add the following case:

People living a subsistence living condition in a village would benefit from receiving assistance from more fortunate people like:‘public health care’ or ‘public education that sustainably improves the quality of their food production (even if they never produce any excess product for trade). But such a person moving from that zero-income and ‘deserving of improvement’ circumstance to a city where they earn income just above the poverty line is not really an improvement. It may, in fact, be a negative change.

Perhaps the most comprehensive recent documents I have seen that attempt to deliver a more accurate presentation are the UNDP Human Development Reports, particularly the HDR 2020 which delves into a diversity of improvements to ‘GDP measures of progress’.

Some other more realistic economic evaluations are:

“Good Economics for Hard Times”, by Abhijt V. Banerjee and Ester Duflo, PublicAffairs 2019.
“The Age of Sustainable Development”, by Jeffrey D. Sachs, Columbia University Press 2015.

Thomas Piketty has also presented some of this non-current-norm economics.

2nd law of thermodynamics contradicts greenhouse theory

Likeitwarm... Your description sounds like a severe case of confirmation bias. You're deliberately rejecting the overwhelming body of research in favor of small cherry-picked bits that confirm what you prefer to believe.

2023 SkS Weekly Climate Change & Global Warming News Roundup #38

nigelj @4,

To be clear, I am optimistic about the future of humanity in spite of the current, and growing, popularity of misleading claims made in pursuit of 'benefit for some - to the detriment of others'.

I believe that the disastrous results of harmful misunderstandings, like the short-term (multiple decades is still short-term) surge of popularity of nonsense like Reagan-Thatcher-nomics (a main driving force opposed to the understood required corrections to limit climate change harm done), will be overcome as global leaders become bolder about taking action that conflicts with the interests of undeserving wealthy and powerful people.

But 'responsible harm reduction' leaders need to have clear support from a significant portion of the population. It is very hard work to limit the harmful influence of misleading populists.

Limiting the influence of misleading populists requires leadership that will compromise the ability of undeserving powerful people to mislead in ways that suit their unjust interests. But, more importantly, it requires a significant portion of voters to be dedicated to learn to be less harmful and more helpful to others. All major political parties sharing that objective but still having a robust diversity of perspectives aligned with that objective would be 'brilliant politicking'.

The battles to 'limit the success of misleading marketing', on all matters that really matter, not just climate science and limiting climate change impacts, need to be won in order for humanity to sustainably improve the future for the robust diversity of humans and other life on this amazing planet. SKS is just one of the many important players in battle against 'mis-Leaders pursuing harmful unjustified unsustainable benefits For Their Type of People.
