Swampfox could you please provide proof of your assertion that rabbit meat contains low nutritional value for humans, because 1) it defies basic commonsense and 2) a quick google search shows a vast quantity of credible publications stating rabbit meat has a particularly high nutritional value for humans. The first three hits are below:

nigelj,
Teresa Coady's book I referred to also points out that tall structures along any migratory bird route is a problem, even off-shore. In addition, marine impacts of off-shore human developments also need proper consideration. Otherwise, putting wind turbines off-shore is just another harmful development akin to "moving coal power plants out of the city" which is the UnSolution of "Problem moved away - perhaps even being more harmful but out of sight so Okay?"

nigelj,
The term "radical environmentalist" is problematic. It can mean anything. I would support the "radical environmentalists" being the ones deciding what happens if they are "radical" by including "Social" considerations in their pursuit of increased awareness and improved understanding of what is going on and the application of their learning to pursue the end of social and environmental harm done by human developments and make amends for harms that have already been caused.
I agree that people should be concerned about the harmful impacts of human development, including harm done to birds.
But the focus of that bird concern deserves to be on buildings that are more than, say, 6 stories tall. There are plenty of easy to access resources explaining that tall buildings kill lots of birds, especially the glass covered ones, especially if they have inside lights on at night. It is likely that a tall building kills more birds than an equally tall wind turbine. So it may be that it would be less harmful for tall buildings to be replaced by 6 storey buildings with wind turbines above them (and the total harmful impacts of building and operating shorter buildings would also be less than the impacts of the tall buildings - "Rebuilding Earth" by Canadian Architect Teresa Coady, is the most recent item I have read that includes this type of information as part of the understanding of how to address the climate change problem and many other problems caused by human development).
But the biggest killers of birds are domesticated cats. And that relates to a "population problem of concern" than can and should be acted on - Reducing the harm of pet over-population. Some domesticated animals are helpful. But many pets cause harm and increase demand for resources. Reducing the harmful impacts and consumption caused by unnecessary Pets could be a helpful step while the human population problem is brought under control by the continued pursuit of the Sustainable Development Goals through the next 40 to 50 years (peak global population may occur in the 2060s).
But even if the human population problem is controlled, the problem of harmful over-consumption by the highest consuming and most harmful portion of the population could persist, even becoming a bigger problem as the total global population declines.
So the real problem/solution is reducing the harmful over-consumption that some humans have developed a liking for. Free choice to believe and do whatever a person wants is not a solution. It is a problem. Reduced the energy demand will reduce the amount of harm done by "required" power generation systems like wind turbines.
The wealthiest are the ones who can afford to live the lowest energy consumption lifestyle. The required global fundamental understanding needs to be that the wealthiest and most powerful should be required to prove they deserve to be wealthier and more powerful by living with less benefit from harmful actions than those who are less fortunate. Wealthier or more powerful people should not be Freer to Choose to be more harmful, even if they can afford it or abuse their power and influence to get away with it.
That "Winning by harmful pursuers of status" is an Age Old Problem. But problems can only be solved by increased awareness of the actual fundamental problem.
Radical environmentalists could be the solution, depending on what type of person that term actually refers to.

swampfoxh at 23:55 PM on 7 December 2021Solar and crop production research shows ‘multi-solving’ climate benefits
I wasn't sure where to start with the above essay, so much of it is grasping for straws. 0.6% of the land necessary to erect solar power grids, then employed for the reasons listed, is itself a discussion about nothing at all. We would be better off just planting trees on an equivalent area on the other side of town, or converting cattle grazing land to riparian. As far as raising rabbit goes, current nutritional science has proven that eating rabbit is equivalent to eating rats, insofar as nutrient values are concerned. There are no nutrient values in rabbit meat...not for humans. Regarding bee habits, we beekeepers know that bees enjoy sunshine and love the floodplain of rivers as forage areas, although they will harvest the nectar of flowering trees, especially tulipfera species which cannot grow under a solar panel. My apologies, I could go on about several other points made in this post, but my essay is long enough as it is. ...someone else's turn.

Don't let radical environmentalists decide what electricity generation gets built, because nothing would get built. Solar power looks relatively benign environmentally. Wind turbines are more problematic because of the big visual footprint on hills that some people dont like, and they kill insects and some birds, lets not pretend otherwise. The solution is really to locate them offshore, something central governmnet should require by law, maybe 50% offshore and gradually increased from there.

UniteHumankind @6,
I understand the intention, but yes, it is very silly. To have any validity, a poll must be taken on a representative sample. Many precautions enter in the rather complex selection process that allows for a representative sample. In your case, not only that is not the case, but you are even down to attempt overcoming a manipulation of the poll with a counter-manipulation maneuver. What validity can the poll have? Close enough to zero to be negligible.

It would be best if radical environmentalists had the final say on site selection, since they have no monetary or political axe to grind. We are happy with eliminating as much fossil fuel usage as possible, but not happy with collateral damage to the environment from insensitive projects.
-
swampfoxh at 01:02 AM on 7 December 20212021 SkS Weekly Climate Change & Global Warming News Roundup #49
We should not lose sight of appropriateness in site selection...and we are. In the rush to renewables, many proposed sites are moneymakers but are deleterious to the environment. Here in Rockbridge/Bottetot County, a wind turbine site proposal has 100% opposition from area radical environmentalists.

One Planet Only Forever at 13:02 PM on 6 December 2021Can genetically engineered seeds prevent a climate-driven food crisis?
John Hartz @2,
Thanks for pointing out the article.
It is an interesting perspective on the well established understanding that has been written about in different ways by many different people in recent years. It alings with the understanding shared by Gaya Herrington after she revisited, and performed an update on, the "The Limits to Growth" study published by the Club of Rome in 1972 (one article about this is The Guardian reporting on her study).
An important understanding is that Over-population is not the real problem. And the population problem is undeniably being more effectively addressed than the climate change problem.
The real problem is harmful over-consumptive ways of living that some humans have developed a liking for. And those harmful over-consumers provide harmful unsustainable examples that others can be tempted to aspire to develop to match or exceed.
There are many sources of information to help people improve their understanding that Total Population is being address and that the harmful over-consumption problem fails to be effectively addressed. People who claim to be concerned just need to act on that concern and become better educated. But it is undeniably difficult to get people to learn something that contradicts their developed preferences or that contradicts something they want to claim to excuse not understanding the real problem. Proof of that difficulty is the lack of effective actions to limit harmful over-consumptive ways of living like the ways of living that cause the growing climate change problem and people continuing to claim that "over-population is the problem".

The Guardian has an article that says the International Energy Agency, IEA, projects that 95% of new electricity generating capacity worldwide from today to 2026 will be renewable energy.
Renewable energy is being built out because it is now cheaper than fossil fuels almost everywhere. This winter coal, gas and oil have increased greatly in price while renewable energy has only increased a little. Hopefully businesses will increase installation of renewable energy to save money. It will help with the climate issue. Every kilowatt generated by renewables is less generated by fossil fuels.
Another article stated that one of the primary bottlenecks for wind energy was obtaining permits to build. Governments can speed up the permitting process to increase renewable energy.

nigelj at 07:41 AM on 5 December 2021Gerrymandering is a climate problem
Swampfox. Your assertions are simply not correct. Numerous polling studies (eg Pew Research) find huge difference on climate issues between republicans and democrats, where republicans are generally more sceptical than democrats about the science, carbon taxes, and wind and solar power (although the gap is smaller for wind and solar power). A simple google search found Democrats far more likely to buy EVs than Republicans. It shouldn't be like this, but it is like this.

what should we do at 06:57 AM on 5 December 2021Thanksgiving advice, 2021: How to deal with climate change-denying Uncle Pete
Unfortunately, there isn't so much information in this post as there is social reinforcement--it goes back to the old trope of the crazy uncle and serves to encourage thinking the other side is stupid.
I also notice that certain supporting information like that the pentagon takes climeat science seriously neglects to mention that all, that is all, of their predictions about climate were wrong. The Climate Discussion Nexus offers a lot of actual, real information without so much "snide." This one is about the Pentagon predictions:
https://www.youtube.com/watch?v=yj83l0mcWUY
We should be focused on the actual pace of change and its effects as well as what to do about it, not scoring points on who was right or wrong all along. This video needs to be posted so it's clear this article is not a font of scientific accuracy, but what we need to do is focus on reasonable action.
This article fails in that way and can only serve as candy for true believers.

One Planet Only Forever at 03:16 AM on 5 December 2021Gerrymandering is a climate problem
Swampfoxh,
It is possible to understand that "What is needed is not support of a political constituency, rather the declarations and positive actions of dictators who, from scientists, know what has to be done." is a misled belief.
Any type of leadership will work. The commonsense requirements is that the leadership (winners) all pursue increased awareness and improved understanding of what is harmful and aggressively act to rapidly end the harmful activity in "the least harmful way", with the political differences being different perspectives that create a diversity of effective ways to rapidly end the harm being done. An important understanding is that "perceptions of harm done by the ending of harmful activity" need to be restricted to concerns to ensure that everybody live at least a basic decent life - No Poverty. It is important to understand that it is not harmful for supposedly superior people to become less superior because harmful activity they benefited from is ended.
The key is to end the nonsense belief that any developed perceptions of prosperity deserve to be maintained as the harmful activity is ended. That legacy argument that excuses incredibly harmful things like oil extraction in California to continue because it "was initially permitted and therefore is grandfathered into being allowed to continue" has to be scrubbed from the system.
Sustainable activity by all of humanity is the only starting point that can be constantly continued or improved on by the development of better "also sustainable harmless" alternatives. Humanity has millions of years to enjoy this planet, so the accumulated impact of actions of each generation have to be essentially harmless.
The challenge of today is "getting to the starting point of all of humanity living sustainably, all people living decently, no harmful poverty". That means everyone learning and pursuing living in ways that are not harmful to others or the environment of the planet that is essential to all future life on this planet (a key point being the understanding that technology can be helpful, but is not essential to life). And the "wealthy and powerful" need to be required to be leaders of the correction of what has developed. The alternatives to that responsible leadership are ultimately disastrous for humanity.
The problem is the small portion of humanity who develop a liking for benefiting from being harmful. That small group have been in control of much of humanity since the earliest days. The evidence is growing that the growth of that type of "controlling people" has always been a harmful growing problem. It has now grown past the point of being able to be ignored or excused. And a growing number of people are realizing that ... including the gerrymandering types using their powers to prolong their ability to be harmful Winners who are just like the harmful dictators and populist pursuers of power.
Something has to be done. Hopefully it will be the Winning by responsible thoughtful people. The alternative is a growing disaster in the making. (btw, the likes of Trump owning a Tesla as one of their personal vehicles obviously does not represent their overall actions and impacts).

swampfoxh at 00:29 AM on 5 December 2021Gerrymandering is a climate problem
There is clearly no connection between sensible, practical and necessary methods to remedy human behavior in seeking solutions to climate and environmental problems, based on political affiliation or the assumed leverage of a majority constituency. People and groups working proactively on climate are doing so with no regard to their own political party affiliations. If Democrats were really better at this work than Republicans, progress would be significant because the Yale study back in 2012 showed that more people identifying as Democrats were delivering support to reducing fossil fuel consumption, but it's Republicans whom are buying the electric cars. What is needed is not support of a political constituency, rather the declarations and positive actions of dictators who, from scientists, know what has to be done. Consequently, nothing will be done. Humans are an outlaw species on planet Earth and will just have to try and pick up the pieces after the coming extinction event runs its course.

One Planet Only Forever at 07:22 AM on 2 December 2021Climate-conscious conservatives try to make their voices heard
swampfoxh,
I have a different perspective regarding current politics.
The real problem has little to do with political identity. It has a lot to do with the "identities being developed by political groups".
My two categories to put people into are:
1. People willing to increase their awareness and understanding of what is going on and learn what is harmful and how they can be less harmful and more helpful to others, including their impacts on the environment beyond their "socioeconomic political environment of the moment".
2. People who have developed beliefs that they desire to protect against the changes that could come from increased awareness and improved understanding of what is "harmful to the future of humanity" and how to be less harmful and more helpful.
There could be a third category of people who are simply unaware. But every member of that group that gets introduced to new thoughts becomes either Group 1 or Group 2 based on their response at that moment. Do they pursue learning to be less harmful and more helpful or resist it?
People who enjoy perceptions of superiority relative to others, and people who want to be "superior" like them, can be understood to be highly motivated to resist learning in the current socioeconomic political environment that has developed a lot of perceptions of superiority built on harmful unsustainable actions.
The lack of interest in learning that the ways a person obtains benefit and perceptions of superiority are unacceptable, especially if it is learned that their ancestors developed the "life style they were born into" through harmful actions meaning that they owe a debt of "systemic change and other compensation" to many of those Others who they consider to be "deserving to be less superior". That is almost an eternal human problem, the victors making up harmfully unjustified justifications for their developed perceptions of Superiority relative to Other people (or other life).
-
nigelj at 06:23 AM on 2 December 2021Can genetically engineered seeds prevent a climate-driven food crisis?
Perhaps this website could do an article on population related to the climate issue and other environmetal issues. However I suggest we know what the viable solutions are: Namely better education, better womens rights, the demographic transition, contraception etc. Most countries are addressing those sorts of things. Some are not doing this so much, often due to religious factors, and short of preaching about it its not clear what more we can do. They are sovereign nations. Its why I think we have to mostly promote renewables and lower consumption etc.
-
nigelj at 06:16 AM on 2 December 2021Climate-conscious conservatives try to make their voices heard
Swampfox @1 & 2. You are right about that. Generally the way systems work in western democracies is you get a progessive reforming governmnet doing its thing for a few years and then a conservative governments gets elected, then back to a progressive governmnet in a cycle. And generally the conservative leaning governments have kept in place many of the progressive reforms, maybe cancelled some of the crazier ones. Its kind of worked ok. You had a consensus between conservatives and progessives over plenty of the important things,
Occasionally you get a governmnet with an excellent balance of reform and restriant but that seems to be rare. Its more often a cyclcial progression of left and right leaning governmnets.
IMHO the problem is in recent years newly elected conservative governmnets have been cancelling every policy of progressive governments they possibly can, and often it seems just out of spite and hatred. Theres often very little logic to what they do. Its become extremely tribal in America. I dont know how that gets fixed. Biden is trying but also faltering.
-
swampfoxh at 04:42 AM on 2 December 2021Climate-conscious conservatives try to make their voices heard
Democrats, on the other hand, are revisionists. They see improvement is always possible. It is often said that Democrats might maintain a point of view reflected in the lyric in Johnny Cash's "Man in Black","...that things will never be right, I know...". Progressives are a group of generic Democrats that have named themselves "Progressives", and are often willing to make changes in most social, economic and political (even religious) systems with no special regard for the suitability of those changes...or even the need for change at all.
Between the two groups, the Republicans and the Democrats? The trick might be to find a way to satisfy the "longing to change things with the longing to leave things the way they are." But, finding that trick? I've not the slighest idea.
-
swampfoxh at 20:33 PM on 1 December 2021Climate-conscious conservatives try to make their voices heard
Republicans shun the climate problem because they resist collectivist action. At bottom, Republicans believe "Man is and end in himself, not a means to the ends of others". Any human action that smacks of collectivism, like socialism, communism or fascism will always be rejected by people who identify as Republicans (generally). Republicans and their "individualism" can participate in fixing the climate problem if they don't feel like they are going to be swept away to a government gulag by Marxist/collectivist style coercion. People who identify as Democrats are always ready to manipulate the social fabric, whether it needs fixing or not. Republicans fear change. That's why there are often called Conservatives.

Wol at 09:57 AM on 1 December 2021Can genetically engineered seeds prevent a climate-driven food crisis?
swampfox: I couldn't agree more.
Comment on overpopulation brings forth instant abuse on most comments' columns - usually snidely asking whether the writer should be the first to drink the koolaid. ie. punishing the messenger.
But it's hard to fathom why it appears taboo across the board when its OBVIOUSLY the fundamental problem.
Not saying there's a solution apart from war, famine, flood and drought. Most of these are well under way without any deliberate "solutions".
You can feel it.

Thus, yesterday, 218,800 more new people are walking the Earth, than on the day before yesterday... and another 218,800 will be added today. Not only are these carbon footprints being added to the GGE problem but each of these are consumption and destruction machines acting against a variety of ecological benefits (clean water, reforestation, carbon sequestration, AMOCs, LUCs, cryosphere change, etc.) Who will come forth to author an expansive essay, similar to the one above, that will remedy the population of humans problem and do so as comprehensively as the above essay has for seeds?

nigelj at 06:17 AM on 26 November 2021Thanksgiving advice, 2021: How to deal with climate change-denying Uncle Pete
Robin, I agree there is no point ruining a family gathering by debating climate change with Uncle Pete, and its best to change the subject. Although I find it takes me an effort of will to do this. I was silently thinking stick a sock in his mouth and sit him in a corner of the room and shove a bottle of whisky in his hand to keep him amused. I know we cant really do this but it was an interesting, satisfying thought.
However what do we do when uncle Pete appears on websites like this? This is more perplexing because he (or she) can sway impressionable people following the discussion that are mildly sceptical. There seems to be a school of thought that says ignore Uncle Petes when they rear their ugly heads in public forums. Engaging with them draws attention to them so its thought. Pretend they don't exist. In my observation climate scientists have mostly done this (this website excepted) but this strategy has obviously not stopped Uncle Pete causing havoc.
Personally I think its better to rebut their claims but without getting too much into an extended one on one debate. If possible dont even use their name. You are really not trying to convince or inform Uncle Pete, but other people involved in the discussion or reading it.
Some people directly engage Uncle Pete partly just to ridicule them and for entertainment. I confess I've sometimes done this myself. But this is a risky strategy because it can alienate people who dont like such harsh treatment and stong language.
Uncle Petes are very frustrating. I wish they would just STFU.

"When we say our blessings at Thanksgiving dinner this year, may our thoughts be for the greater good and our words be carefully parsed for a community and, for that matter, a world that so desperately needs our love, and may the gratitude in our hearts shine toward finding solutions … and being part of them."

MA Rodger at 21:21 PM on 25 November 2021Global CO2 emissions have been flat for a decade, new data reveals
pattimer @1,
The Global Carbon Project correction to FF+LUC anthropogenic CO2 emissions over the last decade is actually very minor. I compared the before-&-after numbers when first published and for that period (from memory) OLS showed they changed from +75Mt(C)/yr to +25Mt(C)/yr. (The increase in emissions had been running at about +200Mt/yr through the preceding two decades.) So an already quite-flat emissions rate through the last decade is revised somewhat more flat. Given the wobbles in the draw-down of emissions our into the biosphere, the calculation of Af is a long-term thing. (It averages 44.3% 1959-2020 with a 2sd variation of +/-25.9%.) So the impact of the adjustment on Af is insignificant. For 2019 the single year figure previously 48.7% becomes 49.1%.
Af will get interesting when we get round to reducing our collective CO2 emissions. The draw-down of CO2 is not a single-year-emissions thing as suggested by the Af but the draw-down of our accumulated CO2 emissions over the decades (& eventually centuries). Thus the 2.99Gt(C) ocean draw-down and 2.92Gt(C) biosphere draw-down estimated by GCP for 2020 would hardily have budged if we had halved emissions in 2020. But if emissions had halved from 10.38Gt(C) to to 5.19Gt(C), the atmospheric levels would have dropped and Af would have turned negative.

Daniel Bailey at 10:24 AM on 25 November 2021Global CO2 emissions have been flat for a decade, new data reveals

Ian Forrester at 05:59 AM on 25 November 2021Global CO2 emissions have been flat for a decade, new data reveals
I had been thinking the same thing. Using data from wood for trees the rise in CO2 during the period 2000 to 2010 is 2.04 ppm /year. The rise from 2010 to present is 2.45 ppm /year, an increase of 20%. Why the discrepancy with the data on CO2 released from burning of fossil fuels?
There are a number of possible reasons. Firstly, the countries may be fudging their CO2 figures. Secondly, another source of CO2 is becoming significant e.g. CO2 from forest fires or melting permafrost. Thirdly, sinks are losing their effectiveness in removing CO2 from the atmosphere.
Any comments?

pattimer at 22:07 PM on 24 November 2021Global CO2 emissions have been flat for a decade, new data reveals
Interesting article. And hello everyone at Skeptical Science. It's been a long time since I have been in touch.
However
I have a question.
If CO2 emissions have been less than previously thought in the past from fossil fuels and land emissions but the atmospheric CO2 is increasing just precisely as we measure it then does this not mean that very worryingly the air borne fraction must be increasing. If so positive carbon feedbacks are coming earlier than we feared? OR Have I missed something?

We are beyond that and now yes it would be equitable to help those in society who may be effected.
However as the article points out those in the lower income level actually benifit with lower energy prices useing Renewable Energy.
What is not to like?

Thank's plincoln24. The En-ROADS simulator is very useful. I have seen it before. Heres the link to it.
But notice it doesn't just allow variables like emissions and types of energy source to be altered. It also allows population and economic growth to be altered. Its in effect a practical application of I = PAT that I posted above.

Comment number 5 is the most useful comment. In some population will always be the cause of every environmental problem. You can't get around that. But there exists ways where people can shift to sustainable living given the current population size. You can see this in En-ROADS for example https://en-roads.climateinteractive.org/scenario.html?v=21.11.0 . If you like you can do a search in YouTube for an explanation of how to use En-ROADS (a world economy and climate model developed by MIT). The UN projections in En-ROADS show that the most likely population projection is one that peaks midcentury and begins to fall.

WOL,
There are reports indicating that total population levels of 12 Billion could live decently, but admittedly without people living in the ways that the wealthier people do today. But it would undeniably be easier for all humans to live as sustainable parts of the robust diversity of life on this planet if there are fewer humans.
The population challenge has a solution that is being worked on and can be improved. The report in The Lancet indicates a total global population of under 7 Billion by 2100 (lower than the current total population) if the SGDs are achieved. Acknowledging that the SDGs are the solution is essential. By all means provide legitimate improvements of any specific aspect of the SDGs or of the understanding presented in the 2020 Human Development Report. Better is Better.
And aligned with nigelj's comment regarding Impacts=PxAxT is the fact that it is important, and possible, to solve the poverty problem by achieving the SDGs without harmful technological developments that unsustainably produce perceptions of superiority or affluence.
Stating "Population is the problem" is a waste of time.
The problem has less to do with the total population and far more to do with the insatiable desire for "Growth of GDP", or any other harmfully unsustainably obtained perception of advancement or superiority. Without sustainably solving that problem even 1 billion humans (or 500 million) will be unsustainable on this planet.
The people perceived to be the highest status need to be the ones living less harmfully, more sustainably, not the backwards way things have been perceived through human history. The perception that people who are more technologically advanced and more willing to benefit from harmful activity are "Superior" has repeatedly failed to produce sustainable improvements.
The European colonizers ruinously spreading their harmful insatiable desires for "More" around the planet is potentially the most harmful human development, along with the related misleading marketing that makes people believe it was "beneficial for the future of humanity". It is possible to understand, from the evidence, that there was no "Population problem" in Turtle Island (N. America) before the insatiable harmful Europeans over-flowing out of Europe arrived.
The sustainable improvements have developed through the hard work of people who recognised how harmful things had become and succeeded in the battle against misleading marketing that glorified harmful unsustainable developments.

I think discussions of the root cause of environmental problems tend to go around in circles because perhaps there is no single root cause. Its more of a related set of causes. There is a simple formula on wikipedia as follows: "I = (PAT) is the mathematical notation of a formula put forward to describe the impact of human activity on the environment."
I = P × A x T
"The expression equates human impact on the environment to a function of three factors: population (P), affluence (A) and technology (T). It is similar in form to the Kaya identity which applies specifically to emissions of the greenhouse gas carbon dioxide."

OPOF >>In spite of it being possible to better understand the issues, the waste-of-time diversionary claim that "Population is the problem" continues to persistently be brought up.<<
Yes, it's a "waste of time" but it is still THE problem whether we like it or not.
I certainly agree that the assumption that capitalism relies on constant growth is doomed to failure. The model has definitely allowed the planet to achieve what it has - standard of living for billions, moon landings, nuclear weapons and the rest - by use of FFs in the main. Obviously exponential growth of GDP as well as population is unsustainable.
It is interesting to look at the widely varying estimates of what population the planet can sustain indefinitely - I've never seen one that is remotely close to the projected 10 - 11Bn even assuming the same percentage are living well below the poverty line.

nigelj >>Agree that there is no answer to the population problem, at least in the short to medium term.<<
I agree with you. However that's not a valid reason for not bringing it up - it's THE problem.
Per capita consumption being addressed - and how's THAT going? - is all very well but running up the "down" escalator slower than it's travelling will never get you anywhere.
Individual decisions to cut consumption won't do much: government laws will result in them being voted out - and it's all the result of overpopulation. (Edited - I initially typed "overCopulation" although that's possibly more relevant...)
I really think the next generation is screwed. I wish it wasn't, but there.

This is going to be blunt but not brief, and it goes beyond the "Climate Science" focus of SkS. But in needs to be all of that to appropriately respond to what has been brought up in comments @1 through @4 (and has repeatedly been unjustifiably been brought up in comments, not just on SkS).
Most Bluntly: The growth in GDP per capita is the problem. Or, more correctly, the harmful unsustainable and inequitable ways that GDP is increased are the problem - regarding more matters that matter than the climate change harm being done by increasing GDP.
GDP has increased faster than the global population, and yet extreme poverty persists, and poverty continues to exist in the nations that are believed to be "very advanced - based on GDP or GNP per capita" (research that point any way you wish - it is fairly irrefutable - part of the story is presented by Worldometer regarding GDP which includes a table of GDP and population data since 1961).
A major part of the problem is the persistence of the incorrect belief that GDP is an appropriate way to measure "advancement". And it is the higher-consuming and higher-impacting portion of the population who most insist on believing that nonsense claim. Read the 2020 Human Development Report to better understand that point, and so much more.
In spite of it being possible to better understand the issues, the waste-of-time diversionary claim that "Population is the problem" continues to persistently be brought up.
Robust confidence that "population growth" is "the problem" is necessary in some minds. Otherwise, the way the highest consuming and impacting portion of the population has to be admitted to be "the major problem". And it also has to be admitted that the highest impacting and consuming portion of the population actually have to give up the harmful aspects of their over-developed ways of living "before a cheaper and easier way to enjoy what they harmfully enjoy is developed" - especially since economic developments (profit and popularity motivated) that are initially thought to be improvements often end up being discovered to have harmful consequences, especially technological developments. And when those harmful developments are popular and profitable they are very hard to limit and it is hard to get all the beneficiaries of the harmful unsustainable activity to pay to amend the harm done.
The population problem is being solved, particularly by the pursuit of important objectives like the Sustainable Development Goals. I have referred to the recent report in The Lancet on several occasions. And Evan included it in the "The Keeling Curve - Part III" here on SkS. Read the report in The Lancet and you will learn that achieving the SDGs is expected to dramatically reduce the global population relative to not achieving those objectives.
Anyone concerned about "The Population Problem" should promote the understanding that their leadership needs to be pushed to do even more to help achieve and improve on the Sustainable Development Goals, even if that achievement reduces perceptions of superiority that some people harmfully undeservedly developed. And the achievement of the SDGs is further justified because it also addresses "the problems of human impacts exceeding the safe limits of the Planetary Boundaries".

Agree that there is no answer to the population problem, at least in the short to medium term. You cannot line people up and shoot them. Which is why I dont waste column inches on the problem. Instead its more useful to promote renewables which does have a future and is viable. Doh!
We just have to hope the low fertility rates in the developed world spread to all countries eventually. I think they probably will. I hope so anyway.

swampfoxh: Beat me to it.
Once again only passing references to population: it appears to be a taboo to even mention it and even then it's a "too hard to solve" problem so is just swept under the carpet.
Meanwhile, while I've been typing that sentence and correcting a typo another 30 lifetime comsumers have entered the food chain.
Population numbers are the fundamental cause of almost all the planet's problems, from migration through water access to climate warmingThe only countries that have attempted even temporary limits have been China (One child policy) and India (a free transistor policy) so far as I know.
There is, frankly, no answer to this.
If you've ever wondered why we've never seen evidence of aliens from the trillions of planets out there it could well be that civilisations evolve to an industrial revolution and it kills them in three or four hundred years.
