Art @ 19 [emphasis added]:
Essentially, humans are combustine engines, so unlike plants and trees, over our lifetimes we emit an enormous amount of CO2 relative to our mass.
Art: meet tree respiration. Tree respiration: meet Art. The two of you obviously don't know each other.
All living organisms consume sugars to produce energy. They do that by burning the sugars. That produces heat, energy, water, and CO2.
Trees and plants are not some magical one-way path that fixes carbon. As they grow, they store carbon - in additional to using large quantities of it as food when they cannot photosynthesize. When they are "eating", they take in O2 and release CO2 - and it really is called "respiration". Once they die and decay, the carbon is released again. Just like humans.
You can actually find resources on the Internet that will explain this to you, if you bother to try.
As for the rest of your post, now you're just playing "Look! Squirrel!". Face it: you do not understand the carbon cycle.

"Humans breathing is indeed a carbon neutral process, but the catch is that more humans = more CO2 in circulation, hence more in the atmosphere."
Read what BL said. Its not increasing atmospheric concentrations of CO2 over time.Thats what matters. Y
"Similarly, we could run all cars and trucks from biofuels and claim that it's a carbon neutral process. We would be technically correct but also stupid"
It is correct, but it isn't stupid. If its carbon neutral its not increasing atmospheric concentrations of CO2, which is the thing we are concerned about. Although personally I believe biofuels have rather a limited future for practical reasons of land availability.
"Anyway, I'm just making the point that human existence is always going to be carbon intensive,"
It is, but so what? The only thing that matters is how much we increase atmospheric concentrations of CO2. Not whether we eat plants or exhale CO2.
We could even continue to be very carbon intensive and capture and store all the fossil fuel emissions we produce, although its not the most economic option, and is completely senseless because we cant maintain a fossil fuel based civilisation for much longer anyway. The resource is finite, and we have already used up all the easy to extract fossil fuels. We are now on the downward slope and will run out, or find the resource is prohibitively costly to extract forcing is to use alternatives.
"and of course most of our emissions stem from the need to remove forests to plant crops and create space for living, working and recreation etc... "
Trying to make it sound like relatively harmless things are causing the problem when the real main underlying culprit is burning fossil fuels.
"And yes it's contentious. So why should a global population policy be any different?...it's all about educating the masses so that we're all aware of the problem, and are all participants in a global solution. "Politicians wont go near something like a global population policy with specific goals on population size etc,etc. Most people dont want politicians in their bedrooms let alone a global coalition of politicians in their bedrooms. And we dont need something like a global population policy, because the problem is largely fixing itself anyway: Population growth is generally already slowing for well known reasons to do with the demographic transition and easier availability of contraceptives.
Our education systems already indirectly raise awareness of the population issues, - without needing to lecture people about it too directly or promote a partcular family size. I dont oppose more explicit education but I cant see schools and governmnts going near such an issue because of the huge potential public backlash.
I don't think theres much more we can do to speed up the de-growth process already underway. And population decline cannot possibly happen quickly enough to be a factor in keeping warming under 2 degrees. It might have some small effect on keeping warming under 8 degrees but by then it would be too late to be useful to us anyway.
"You're (MAR) obviously banking on a lot of new tech in a very short space of time. Good luck with that. "Your underlying point seems to be that the transition to renewables will require burning of fossil fuels to manufacture a new energy grid. The quantity of energy needed to make a new energy grid is vastly less than total quantity of just continuing to burn fossil fuels with all the warming that will cause. This is literally intuitively very obvious and experts have done the maths.

Bob Loblaw @ 18, "..and those plants would have decayed into heat and CO2 anyway. Storing them in humans with typical life spans of 60+ years after they "stop growing" delays that decomposition by 60+ years. That slows the carbon cycle down, not speeds it up.
You don't get to pick and chose which parts of the carbon cycle you want to include in your accounting scheme."
Thanks Bob.... Probably best not let discussion get bogged down on this specific point. I did consult with an old professor of geology some time ago, so I always defer to his analysis... The assumption that humans exhaling is carbon neutral is correct but there's an inconvenient caveat, and there's no shortage of misinformation. Essentially, humans are combustine engines, so unlike plants and trees, over our lifetimes we emit an enormous amount of CO2 relative to our mass. In fact, we eat roughly our body mass every few weeks. You could argue that our existence is at the expense of other respiring animals - which offsets our impact on the carbon cycle, but all such arguements whether correct or not are ultimately spurious, because as we're all aware most of our impact on the carbon cycle, aside from fossil fuel combustion, comes from the clearing and burning of large proportions of the world's natural forests for food production, living space and lifestyle. Some of our activities and agri practices also increase the natural levels of methane and other greenhouse gasses which further adds to the greenhouse problem.
So, our collective respiration of CO2, although around 10% of global total CO2 emissions, which seems like a big number, is a problem we can easily exist with, and indeed there's probably some benefit to CO2 levels in the atmosphere higher than pre-industrial. On the other hand, our existence, at the expense of huge amounts of the biosphere is a HUGE problem.

Now, if you want to discuss the role of agriculture and how that alters soil and biomass carbon storage and cycling vs. natural systems, then go for it. But "humans = more CO2 in circulation" is a gross (and incorrect) simplification.

Bob Loblaw @ 16, "More humans = more carbon stored in a fixed reservoir. As biomass accumulates, increasing the number of humans acts as a carbon sink."
Except that more humans = the exact opposite. Our mass comes from the carbon stored in the plants that we ate and continue to eat, and after we stop growing at around 16 years we operate as pure combustion engines, converting carbon from plants into heat and carbon dioxide.

Reducing CO2 emisisons isn't easy either, but we're doing it, and we're doing it beacuse we've collectively put systems in place that we've all agreed to, and we now have a timeline of target commitments. And yes it's contentious. So why should a global population policy be any different? We already know that the real carrying capacity of the world is almost a quarter of the current population, and it's not too difficult to work out the ideal population for each and every country or region of the world. A commitment doesn't need to be hugely ambitious, nor does it need to involve lining people up in front of firing squads as many people often suggest when the issue is raised. As we've seen with climate change, it's all about educating the masses so that we're all aware of the problem, and are all participants in a global solution.
MA Rodger @ 14..."Does not the developed world construct cars, build high rise commercial developments, manufacture steel and concrete? They will be doing this in a net zero economy, indeed a net-negative-emissions economy. This is the future of the developed world."
It may well be the future of the developed world but the question is 'when'. You're obviously banking on a lot of new tech in a very short space of time. Good luck with that. Realistically, the developing world isn't going to be waiting around for zero or net-zero carbon technology to be developed and refined to the point of being cost-effective before it matures to first world status. There's nothing wrong with being glass-half-full, but at the same time we need to be guided by reality and common sense.

EddieEvans at 01:03 AM on 8 November 2022CO2 is plant food
I see a big need to date these comments. Earth is closer to 420 ppm CO2 today than the "320 ppm" seen below: CO2 is plant food
Earth's current atmospheric CO2 concentration is almost 390 parts per million (ppm). Adding another 300 ppm of CO2 to the air has been shown by literally thousands of experiments to greatly increase the growth or biomass production of nearly all plants. This growth stimulation occurs because CO2 is one of the two raw materials (the other being water) that are required for photosynthesis. Hence, CO2 is actually the "food" that sustains essentially all plants on the face of the earth, as well as those in the sea. And the more CO2 they "eat" (absorb from the air or water), the bigger and better they grow. (source: Plants Need CO2)

I fear what is not remotely sustainable is your argument.
Does not the developed world construct cars, build high rise commercial developments, manufacture steel and concrete? They will be doing this in a net zero economy, indeed a net-negative-emissions economy. This is the future of the developed world. You argue that the developing world will not be a part of this because they will be constructing cars, building high rise commercial developments and manufacturing steel and concrete just like the developed world, but will be using FFs. Why would that be? -

Secondly you make youself look like a denier if you promote that humans breathing is the problem. Humans breathing is a carbon neutral process. Look it up on the list of climate myths on the LHS of this page. And obviously we cant stop breathing so the point is moot.
Thirdly, while I agree that population growth is a problem, what do you suggest we do about it? Because we obviously can't line people up and shoot them and enforced one child policies are a big problem. About all government's can do is make contraception freely available and make sure family planning is taught in school. However even that gets contentious.
In fact the demographic transition and spread of contraception means population growth is slowing in most places, two child families are becoming the norm, and population growth will probably stop eventually even in Africa. There's just not a whole lot more we can do to influence Africa and the established downwards trends in developed and most developing countries. And that is why the focus must be on renewable energy, electric transport, and trying to reduce levels of per capita consumption.

MA Rodger @8 ...
" you assert will see rising emissions resulting from the underdeveloped societies "seeking a more first world existence in coming decades," a "first world existence" that has itself become non-emitting."
You're overlooking emissions as a consequence of building 'first world' infrastructure and industry, which includes transportation, high rise commercial development in towns and cities and first-world housing etc. That's a lot of concrete, steel etc and those materials must be mined, refined and transported, often from other countries and over vast distances.
"You are generally ignoring the goal of developed societies to reduce their own emissions to net zero, indeed to go beyond into the realm of net negative emissions."
Not ignoring, just focused on the developing nations who are responsible for the bulk of global emissions, and importantly, the majority of future global emissions this century.
"You also assert that "the transition towards a low carbon future" will involve a period of increased emissions. If a portion of the carbon-emitting economy is put to the task of building the non-emitting infrastructure, it may be thus engaged in more carbon-intense activities but I would be surprised if any impact on CO2 emissions were significant, especially given the delivery of non-emitting power follows close behind."
Leaving aside rebuilding the world's energy sector, replacing one billion motor vehicles alone is surely an enormously carbon intensive transition, necessitating the mining, processing, and transportation of raw and processed materials on an enormous scale. Studies indicate that EV's incur a higher carbon footprint than ICEV's during the manufacturing process, and the payback peried is over many years. Assuming that new demand for motor vehicles will also come from developing nations it raises the prospect of perhaps double the number of motor vehicles globally in coming decades. It begs the question of whether that's remotely sustainable.
NIJELJ @8 .."However I personally think both fossil fuel emissions and population growth are problems."
Population is definitely a huge issue if we deem current first world standards of living (and consumption) as a point of reference for the future. And regardless of our living standards humans will emit CO2 because humans are essentially organic combustion engines. Not only do we exhale about 10% of global CO2, our existance is at the expense of vast amounts of natural forest for both habitation and food production, both of which are highly emissive, with or without renewable energy.
At some point in the not-too-distant future we will be forced to have some difficult conversations to do with sustainable lifestyle and population, and come to an acceptance that CO2 emissions from fossil fuels is just one aspect of a much larger problem that no amount of wind and solar energy energy can ever solve.

nigelj @10,
A minor nitpick.
Though "The other alternative of just not using energy is not realistic.", the other 'other alternative' of reduced energy use by the biggest energy users, in parallel with the rapid development of renewable energy systems, would more rapidly end the increasing harm done by continued fossil fuel use.
Reduced energy demand would also reduce the harm done by the renewable energy systems. There would be less energy demand.
Limiting the harm done is the objective, or should be. The alternative would appear to be 'no long-term future for humanity'.

"Regardless of population rising or not, the "developing world" still consitutes 2/3 of global CO2 emissions.....Given that >50% of the developing world is still living in poverty it amounts to a large number of people who will be seeking a more first world existence in coming decades, so we can only expect CO2 emissions to rise for many decades, as a result of increased energy demand, food production, land clearing, transportation, urbanisation etc. "
There is a sliver lining to the cloud. Africa is in the developoing world and aspire to better lifestyles (and their population is increasing) but their per capita emissions are low because they dont have much fossil fuel infrastructure. This means they could in theory transition directly to renewables without going through the whole fossil fuels phase. This is happening to some extent with rural areas buying solar panels. Its not a panacea because they will be importing panels, but it helps a bit.
"Take-up of renewable energy will offset this to some extent but development itself is a highly emissive process. Indeed, the transition towards a low carbon future will itself also involve an enormous 'burp' of CO2 due to the mining, manufacturing, transportation and construction on enormous scales required to upgrade the world's energy and transport sectors.
If fossil fuel energy isnt used to build solar and wind power it will be used to build coal fired power or something else, so isn't the point somewhat moot? The other alternative of just not using energy is not realistic.

Want to briefly clarify that my statement that poor people and poor countries still have a huge environmental footprint was a general statement about impacts. For example conversion of natural habitat to farming, altering of water courses,etc,etc. Such people clearly have low per capita CO2 emissions. And my intent was to show that we shouldn't ever downplay potential crises, whether population problems or climate change or anything else. However I personally think both fossil fuel emissions and population growth are problems.

One Planet Only Forever at 01:10 AM on 7 November 2022Climate Change's Controversial Policy: Loss & Damage
My comment @4 brings to mind additional considerations regarding the challenges of determining the Truth and proper Reconciliation of climate change Loss and Damages.
An obviously challenging developed reality is that people who want to benefit, or who have benefited, from harmful beliefs and actions causing Loss and Damage cannot be allowed to influence the determination of how much Loss and Damage has occurred or the appropriate Reparations.
And that challenging developed reality, harmfully developed human behaviour - not fundamental human nature, applies to far more cases of 'Benefiting from causing Loss and Damages' than the beliefs and actions causing continued climate change impacts.

MA Rodger at 18:42 PM on 6 November 2022Skeptical Science New Research for Week #43 2022
Art Vandelay @7,
You shift you argument onto entirely new ground with this latest post.
You new position is that emissions will grow as underdeveloped societies become more wealthy. You are generally ignoring the goal of developed societies to reduce their own emissions to net zero, indeed to go beyond into the realm of net negative emissions. All this is in those same "coming decades" you assert will see rising emissions resulting from the underdeveloped societies "seeking a more first world existence in coming decades," a "first world existence" that has itself become non-emitting.
You also assert that "the transition towards a low carbon future" will involve a period of increased emissions. If a portion of the carbon-emitting economy is put to the task of building the non-emitting infrastructure, it may be thus engaged in more carbon-intense activities but I would be surprised if any impact on CO2 emissions were significant, especially given the delivery of non-emitting power follows close behind. The explanation of China's high CO2 emissions is surely because China took on so much of the existing high CO2-emitting activities previously carried out by the West. Again, the building of non-emitting infrastructure is not a factor that I see at work.

One Planet Only Forever at 14:39 PM on 6 November 2022Climate Change's Controversial Policy: Loss & Damage
Walschuler and Art Vandelay have presented some valid points.
There is more to consider regarding climate change impact Loss and Damages.
Loss and damage, or reparations, is challenging (and challenged). It requires the development of adaptations by the highest harming per capita portion of the population. They need to make amends for harmful past, present and future actions they benefit(ed) from. They need to:
- admit that harmful beliefs and related actions developed in the past and continue to be popular and profitable today. The past harm includes the injustice of developed perceptions of prosperity and status and the inequitable advantages that development created.
- recognize the current continuing harm and harmful developed systemic problems.
- understand that there will be future harm done that people need to be compensated for until the harmful beliefs and resulting actions are effectively limited. The improvement of awareness and understanding, especially among the wealthy and powerful, needs to be significant enough to ensure that collective governing will limit the harmful impacts.
A key consideration is that undeserving beneficiaries of harmful beliefs and actions will try to delay corrections that reduce their perceptions of prosperity and status. Delaying the reduction of harmful pursuits of benefit makes the required future adaptation more severe. And that can make it harder to get support from people who understandably should suffer any required negative consequences.
The delayed reduction of per capita impacts by the harmfully over-developed portion of the global population is building a more damaging situation, including more vicious fighting against deserved losses by undeserving (damaging) wealthy and powerful people.
A major impediment to the understandably required corrections is the perceptions of prosperity and status hat developed via benefiting from unjustified beliefs that excuse harmful unsustainable beliefs, systems and actions.
Admitting to the need for compensation for loss and damage due to climate change impacts understandably includes compensation for harm done by the past harmful development of perceptions of superiority. That is a slippery slope for the wealthy and powerful. Some wealth and power is legitimately obtained by developing sustainable improvements for humanity. But a lot of current day wealth and power is almost certain to be due to harmful actions and the promotion of harmful unjustified claims and excuses.
Admitting to the need for Loss and Damage requires the current day wealthy and powerful to admit that they do not deserve their developed perceptions of status. And it requires them to decide how they will:
- collectively penalize themselves to stop the developed harmful pursuits of benefit
- adequately compensate and correct for all of the harm done everything that contributed to their acquisition of higher status.
Regarding insurance:
The wealthy profit from private insurance programs. They have been reported to harmfully operate private insurance to maximize their profitability. Their actions include declaring that the circumstances some people needing assistance are in make them ineligible for insurance. In addition, the harmful among the wealthy and powerful have a history of abusing their influence on leadership to limit government assistance programs or have those programs implemented in ways that they benefit from.
The required adaptation is clearly the dramatic rapid reduction of harmful unsustainable pursuits of perceptions of prosperity and status relative to others.
The obvious challenge is overcoming the developed powerful resistance to the required adaptation actions.

Regardless of population rising or not, the "developing world" still consitutes 2/3 of global CO2 emissions. The importance of that stat is to underscore the significance of population as a metric for emissions. Given that >50% of the developing world is still living in poverty it amounts to a large number of people who will be seeking a more first world existence in coming decades, so we can only expect CO2 emissions to rise for many decades, as a result of increased energy demand, food production, land clearing, transportation, urbanisation etc. Take-up of renewable energy will offset this to some extent but development itself is a highly emissive process. Indeed, the transition towards a low carbon future will itself also involve an enormous 'burp' of CO2 due to the mining, manufacturing, transportation and construction on enormous scales required to upgrade the world's energy and transport sectors.

-
walschuler at 08:17 AM on 4 November 2022Climate Change's Controversial Policy: Loss & Damage
I would add to the excellent presentation that some of the key questions include:
What precedents exist for dealing with other forms of environmental damage? Can those who pay damages specify how the money is spent by the damaged populations? In view of the universal nature of the climate crisis and the size of the damages already caused and upcoming due to inaction can we afford not to have pretty good control of how the money is spent? Private insurance has a role to play for some cases, perhaps the most localized cases. Also, the government insurance might have roles. In the US the Price-Anderson Act limits the liability of power companies operating nuclear reactors to $450mill per reactor plus up to about 100reactors at $120mill each or $12bill. This money is either by private carriers or assessed as fees to the power companies, which might possibly be recovered later in their utility rates. There is also an arrangement for cases of US makers whose reactors are in foreign countries. See https://crsreports.congress.gov/product/pdf/IF/IF10821. Perhaps there are lessons there. I wonder if there are similar arngements for nukes in Japan or Germany. A downside of such insurance schemes is that they often take al ong time to settle, and we need action world-wide. China is ramping up its solar rapidly and has caused a drop in its costs which has contributed to adoption in the US and elsewhere, but has also installed and continues to install more coal powerplants. India is building coal fired powerplants too. Perhaps the role of already industrialized countries should be first and most urgently to subsidize renewables world-wide, to the extent that developing countries get them at a cost that undercuts the cheapest fossil plants by some modest amount. Such subsidies might count against past damages. Electrification network costs, which might be mostly independent of power source types and costs, ought to be borne by the developing countries and installed with future capacity needs in mind. (The future capacity is another problem. Should we all be looking to cap it or to make it indefinitely expandable?)

1988 was the hottest year on record, up to that date. That probably helped spawn the Global Warming movement. It never warmed enough to matter to people much, so that movement didn't flourish, and we are still seeing lots of migration in the US to warmer cities.
Moderator Response:[BL] Frankly, you have no idea what you are talking about. I was an undergraduate student in the 1970s, when global warming and climate change was part of the curriculum.

Art Vandelay @5,
I think if you look properly, the emissions from countries with significant rising population is far lower than 'around two thirds' the total. The territorial emissions from what we can call 'the developed world' does constitute a third of the global total. Add in China and it becomes two thirds.
And China's population is not rising any more.
The place where there is a significant projected increase in population is Africa.
But Africa is presently the source of just 3.7% of CO2 emission.

Scientists have attributed recent rain in Australia to the Tongan volcanic blast earlier this year. The blast has temporarily increased stratospheric water vapor over the Antarctic, resulting in a strengening of the polar vortex - and a positive 'SAM' "When the polar vortex and SAM are stronger than usual, like they are now, the powerful westerlies stay closer to Antarctica. Therefore, southern Australia sees fewer colder fronts and less windy weather.

Unfortunately this has conspired with La Niña as well as IOD (Indian ocean dipole) to increase the liklihood of rain across eastern Australia.

"Some of this is very high per capita consumption in developed countries, but even lower consuming people in poor countries have a huge environmental footprint, because of the sheer size of their populations."
True, and in fact developing countries account for around two thirds of global emissions, and rising, so population is indeed the elephant in the room.

One Planet Only Forever at 01:39 AM on 2 November 2022How sea level rise contributes to billions in extra damage during hurricanes
The following quote from the opening statements of the article provide an example of the difficulty of clearly communicating in English, a language that is very flexible in its use and interpretation.
"Had Ian hit a century ago, when sea levels were about a foot lower, the storm probably would have caused billions less in storm surge damage, ..."
When I read that statement I understand the point that lower sea levels would result in less less storm surge damage, and that recent human climate change impacts have resulted in a higher sea level. But someone not wanting to understand that 'fossil fuel use needs to be rapidly ended because of the harmful climate change impacts' could 'fail to read and understand the entire document' and simplistically argue that "Of course there would have been less damage 100 years ago. There was less built back then. This big article and its referenced studies are just another verbose presentation of non-sense"
It usually takes more words to be clearer with little chance of 'alternative understanding'. That is why legal and insurance documents are so wordy.
A clearer statement would have been like:
"Had a storm of recent climate change intensified strength like Ian, intensified by being over warmer waters with more energy and moisture in the atmosphere, hit with sea levels as low as they were a century ago, before the human induced climate change increase of sea levels, when sea levels were about a foot lower, the storm probably would have caused billions less in storm surge damage to the current day developments hit by Ian."
Harmful Populists promote harmful misunderstandings by keeping their statements simple in harmfully selective ways. Their claims are irrational and difficult to defend, making them unable to be common sense in a 'learning population'. That is why they attack anyone who would 'ask embarrassing questions they cannot provide common sense answers to as explanations of their claims'. Harmful Populists also 'evade questions they cannot answer with common sense explanations' and attempt to discredit anyone who presents better, more sensible, understanding that contradicts what they want 'common people' to believe.

MA Rodger at 19:58 PM on 1 November 2022CO2 effect is saturated
The commenter currently shown @667 and naming themself 'Spooker' claims to have been awarded a PhD in Physics and asks whether it should have occurred to others that perhaps 'Spooker' "already know(s) the basic science behind the GHE."
It is not unknown for those who are very well versed in Physics to be for some reason incapable of grasping the mechanisms of the greenhouse effect and deny it exists. William Happer was such a one (I think recently he has been used as a co-author in work that does present the existence of AGW but of a much diminished form, a la the likes of Dickie Lindzen), although he does have the excuse of being very old and, as the adage goes, 'you can't teach an old dog new tricks'.
What I would ask this commenter presently calling themself Spooker, and ask in a sciency-physics sort of way, if all the IR emitted by the planet surface is absorbed by the CO2 in the atmosphere above within metres of the surface (which for the central specrtum of the CO2 emissions spectrum at ~666cm^-1 is true) and thus cannot impact the planetary energy balance at the top of the atmosphere, where does all the other IR come from? For instance, what is the source of all the downwelling IR that can be seen by instruments on the surface.
The graphic demonstrating such measurement below was sourced from here.

Spooker @667 & many now evanescent posts :-
You are far too modest about your PhD in Physics (Acoustics, I hear?). And you are even more modest about your double Laureate ~ which is in the pipeline (as I hear, from friends in Stockholm).
Which all makes it so puzzling that your confidence you understand "saturation" (re GHE) seems in a clear contradiction to your evident failure to comprehend GHE.
(~ At least, as far as can be determined from your many posts.) But perhaps you can clarify why you think some form of "saturation" is relevant to GHE . . . and at the same time clarify how & why you are correct about GHE while the generality of atmospheric physicists are grossly wrong about GHE.

Americans are up to 30 percent more likely to have a heart attack in winter because the cold weather narrows blood vessels which raises blood pressure and pulse rate, increasing the risk of a heart attack.
The increased blood pressure and increased heart rate from the cold of winter also raise the risk of stroke.
Below 60 degrees people without much clothing on, can and do get hypothermia and freeze to death.
https://survivaldispatch.com/freezing-to-death-in-60-degree-weather/
In Cleveland, the average high temperature is 61 and the average low temperature is 44, so there is a significant risk of dying from hypothermia if a person is outside for a long time with few clothes on. There are homeless shelters to protect homeless people from the cold weather.

Dear Moderator,
My only point about the robot CO2 sensor was that it measured both CO2 release and absorption by the ocean so both those two actions are happening. I saw it on a video a while back so I didn't have a link to post.
Moderator Response:[BL] Oh, my! Stop the presses! Sometimes oceans absorb CO2, Sometimes they release it!
I would say that your point is trivial, but when you first brought up ocean CO2, you claimed that warmer oceans released CO2. Twice. No, three times. Then you made reference to the "robot CO2" stuff in an attempt to justify those bogus claims.
You are back-pedalling, and it exposes your poorly-thought-out arguments.

Dear negelj, I don't know the details of the past Global Warming movement or while they were formed but when it collapsed the next movement couldn't be called Global Warming since that name had already been used and Global Cooling had also been used they decided to use the slogan "Climate Change" for their movement. They basically are calling the weather the climate of the Earth which is false. The climate of the Earth is a 2.588 million-year ice age called the Quaternary Glaciation. https://en.wikipedia.org/wiki/Quaternary_glaciation

Here are two large international studies that show that deaths caused by excess cold substantially exceed deaths caused by excess heat.
e have 4.5 million people dying each year from moderately cold weather-related causes, mainly from strokes and heart attacks caused by moderate cold, while only about 500,000 are dying from heat-related causes and most of them were also from moderate heat.

"I've been through the Global Warming movement in the 80s that said that the world would be very hot by now and here it is 40 years later still saying it will be very hot sometime in the future. I'm skeptical."
Please provide a link to back up your claims and precisely what you mean by very hot. There might have been some environmental activists and a couple of scientists thinking the world would be very hot by now , ( meaning I assume at least 2 or 3 degrees of warming above preindustrial?), but there was no consensus of climate scientists back in 1980s predicting such a thing.
The first IPCC report was released in 1990. It reviewed the scientific work of thousands of scientists and concluded we could have several degrees of warming by the end of this century, and that warming between 1990 and 2025 would be about 1 degree C. Warming has been about 0.75 deg C over that period so not far off. And bear in mind the modelling back then was not very advanced. This is from the 1990 summary for policy makers:
"Under the IPC C Business-as-Usual (Scenario A ) emissions of greenhouse gases, a rate of increase of global-mean temperature during the next century of about 0.3°C per decade (with an uncertainty range of 0.2°C to 0.5°C per decade); this is greater than thaat seen over the past 10,000 years. This will result in a likely increase in global-mean temperature of about 1°C above the present value by 2025 and 3°C before the end of the next century. The rise will not be steady because of the influence of other factors"

@666 , once again you demonstrate a disconnect from GHE concept.
The fault is not in your stars, but in yourself [excuse Caesar misquote].
Please start afresh. Forget "saturation". Look at the molecules, look at the intermolecular distances, look at the absorptions & radiations. Think about what is going on at that basic level. This is basic physics. This is reality. Scientists (excluding Angstrom) understand GHE because it is straightforward ~ when you stop to think it through.

TheSpook @664 ,
again and again in this thread, you seem to be struggling to understand the concept of saturation and its relevance to GHE. This is stuff which is in textbooks and it is straightforward, if you put your mind to it. And yet your thoughts seem locked in a futile circle of misunderstanding, and therefore you are wasting your time with excessive repetition.
Best if you start with a clean sheet ~ firstly define the term saturation (as you understand the meaning and significance of the term). Then link that to the concepts of the mechanism of GHE.
Somewhere, you yourself have a semantic and/or logical problem which is impeding your your understanding of what is basically a straightforward concept, namely GHE (of one or several gasses).

Southern Ocean storms cause outgassing of carbon dioxide
January 25, 2022
University of Gothenburg
Summary:
Storms over the waters around Antarctica drive an outgassing of carbon dioxide into the atmosphere, according to a new international study. The research group used advanced ocean robots for the study, which provides a better understanding of climate change and can lead to better global climate models.https://www.sciencedaily.com/releases/2022/01/220125112530.htm
Moderator Response:[BL] After several attempts to get you to do so, you finally provide a link to your "robot CO2" claims.
Now that we see the actual paper, we see that it refers to one area of the ocean (Antarctic), and refers to specific meteorological conditions (storms). A quote from the paper:
"We show how the intense storms that often occur in the region increase ocean mixing and bring carbon dioxide-rich waters from the deep to the surface. This drives an outgassing of carbon dioxide from the ocean to the atmosphere. There has been a lack of knowledge about these complex processes, so the study is an important key to understanding the Southern Ocean's significance for the climate and the global carbon budget," says Sebastiaan Swart, professor of oceanography at the University of Gothenburg and co-author of the study.
Once again you confuse a local pattern, under limited conditions, and treat this as if it represents a long-term global effect. You really need to read past the summary of the paper.
And please turn your links into links. You've been told how.

The 297 observations from the Weather Underground site is a large enough sample so that approximate methods, when other methods are not available, is a good way to analyze the data. Taking a small sample of 10 is definitely not a good way to compare categories. I am not saying that it is any kind of proof, next year might warm up, but it is suggestive of cooling rather than warming since the beginning of the year in Cleveland. I don't use Twitter for anything serious and seldom use it at all.

I've been through the Global Warming movement in the 80s that said that the world would be very hot by now and here it is 40 years later still saying it will be very hot sometime in the future. I'm skeptical. The Climate Change articles usually do not even mention that the current climate of the Earth, as a whole, is an ice age called the Quaternary Glaciation and that won't change until all the natural ice melts and we will probably have another glacial period before that occurs.
https://en.wikipedia.org/wiki/Quaternary_glaciation
It should only take a few years to find out if Dr. Zharkova is correct or not. Dr. Zharkova was the one that asked for a retraction, the other authors disagreed, maybe they just wanted to add a correction.
Moderator Response:[BL] Sample size has nothing to do with the failures of your "count days above or below normal" technique.
You have been pointed to articles here at SkS that cover glacial climates. Here is another one:
https://skepticalscience.com/from-email-bag-Ellis-Palmer.html
The idea that people are ignoring glacial climates is absurd, and a figment of your imagination. In the above article, you will find additional links to SkS and other posts on glaciation. It also serves as an example of how "published" papers can be horribly wrong.
Frankly, it is obvious that you will not read or cannot understand anything that does not fit your misconceptions.
You are getting your Zharkovas mixed up. V V Zharkova is the first author, and did not agree to the retraction. S I Zharkov is the third author (VV's son), and agreed to the retraction. And none of the authors requested the retraction - it was the result of other pointing out the obvious gross errors, and the editors of the journal realizing that the paper was not worthy of publication. If you read the PubPeer discussion of the retracted paper, you will see that V V Zharkova doubled-down, tripled-down, and quadrupled-down on the legitimacy of the paper, in spite of people explaining her errors to her.

The TSI data linked by scvblwxq1@6 shows the TSI for sunspot cycle 25 to-date, so TSI for the period 2018-to-date. The same website also gives TSI data back to the start of the satellite record, so since the end of 1978 (sunspot cycles 21 to 24). Comparing the two data sets (they need splicing together) shows the rise in TSI so far for sunspot cycle 25 has yet to top the peak of sunspot cycle 24, itself a rather weak sunspot cycle, as the graphic of sunspot numbers below suggests.
Moderator Response:[BL] Thank you for your efforts. This is yet another case where the sources quoted by scvblwxq1 do not support the position argued by scvblwxq1. We are seeing out-of-context quotes, inaccurate descriptions of the contents of papers, and selective presentation of data.
If scvblwxq1 was unaware of how the recent TSI data fit into the long-term trend, scvblwxq1 needs to reflect on why (s)he was unaware - and how to avoid such errors in the future. If scvblwxq1 was aware, then scvblwxq1 is not engaging in proper discussion.
