MA Rodger at 21:01 PM on 27 December 2022Human CO2 is a tiny % of CO2 emissions
The source of the 77.5 t(CO2)/acre quoted @258 is shown in the link @366. It is not a figure for annual sequestration (which is evidently being expected @358 and which would be a few percentage points of this 77.5t figure) but total sequestration. And I think it is too low. It is derived from cocoa plantations so a figure which may not be representative of replanted global woodlands.
In numbers I am more familiar with, 77.5t(CO2)/acre is (as the link says) 191.6t(CO2)/ha or [x100/3.664=] 5,200t(C)/sq km.
Over the period 2010-19, there has been 53M ha of lost tropical forest (according to OurWorldInData). And since AD1850, the figure given is 1,400M ha. The Global Carbon Project give budgets showing estimated emissions from land-use-change (this mainly due to deforestation) as 13Gt(C) for 2010-19 and 203Gt(C) since AD1850. These numbers suggest a carbon sequestration intensity for natural woodland of 24,500t(C)/sq km or 14,500t(C)/sq km, the former figure tropical, the latter perhaps global. These numbers are far greater than that given in the #366 link.
We can dodge calculating the annual uptake by considering how many sq km of forest would need to be planted to draw down today's annual CO2 emissions (which would be necessary to stabalise GHG forcing). That would be roughly 500,000 sq km or 0.3% of global land, or 0.5% of the 100M sq km global productive land, annually. Note that globally 38M sq km is currently forested, and a similar amount would be naturally scrub or grassland so also not very useful for sequestering our CO2. Thus the potential for land available to sequester our FF CO2 emissions would be somewhere near 25M sq km and such a level of replanting would provide sequestration for perhaps 50 years of our FF emissions at present levels of FF-use.

Slumgullionridge @71 :
Fair enough. SkepticalScience was set up as an educational resource. With its long list of Most Used Climate Myths , it provides you (or anyone) a reasonably quick & efficient way to gain scientific knowledge about climate. You can wade through the Myths one after the other, in turn. Or if you already have moderately good background knowledge, then you can pick out those Myths which fill the gaps (and read the discussions of the peer-reviewed studies, to be found in the comments columns there). I must confess I have not found a better website for that educational purpose.
The problem then becomes: what do you do when you have achieved a high passing grade in the comprehension of climate science? I do not mean by that, the achievement of mastery & expertise in all the minutiae & technicalities, I mean, enough knowledge to see that the mainstream climate science is correct ~ and the skeptics/contrarians haven't a leg to stand on (despite their repetitious assertions).
I guess you then consider retiring to your cabin by the lake, and dismissing the climate problem from your mind. Or you consider spending some time on the subsequent aspect ~ what to actually do, in terms of political science, ethics, and so on. Plenty of room there for hot-headed conversations . . . most of which crop up in the ephemeral/daily topic threads (such as the one where you are now posting).
Some amount of rhetoric & pomposity is almost inescapable in discussing political matters. ~ Just the nature of the beast.

I have been with Skeptical Science for about 6 months. I joined on a recommendation of a colleague of mine, a climate science associate who is a peer review committeeperson serving as Editor for the authors of a new study to be published in spring. I'm struck by the plethora of social science commentary on this site, contrasted to my expectation to be exposed to peer-reviewed hard science. I wanted to see commentary on the progress of climate science, instead it seems like the comments belong in a compendium of social science...which I have a full library of, behind my desk in English 301. I do appreciate the expansive listing of peer-reviewed studies precedent to the "comments" rhetoric, but I was hoping to see commentary about the studies, not so much about political science, ethics, or philosophy.

I'm usually the perennial optimist, but when it comes to Twitter I genuinely believe it's a lost cause. The fundamental business model is predicated on the need for revenues, by way of the fact it is a centralized business with investors and a large base of employee/engineers. The way they generate revenue is to code algorithms so that interations between users generate maximum activity to generate the most revenue possible. That maximum activity is primarily going to be a function of users attacking each other. But the company has to keep a lid on the exchanges in order to maintain advertisers for revenue.
I think Twitter was (prior to Musk) doing it's best to thread that needle, and that meant no one was ever really happy with the situation. Elon Musk's version of the business model was merely to come in and take one side on all arguments without fully understanding what he was doing.
My personal opinion is that Twitter is a total loss. I think it will be out of business in the next 12 to 18 months.

I hope that Skeptical Science does not leave Twitter. I'm a mature, educated adult, an English Professor and am world travelled. I can tell the difference between types of speech and am not uncomfortable having to sift through such material to get to where I would like to go. I do have a neighborhood family that chooses to live in a home surrounded by "refuse" and the whiff of marijuana, but I can navigate around that without analyzing who's being "harmful" or "hateful" or "pompous" or "full of rhetoric"...and I'm hopeful all of you can navigate around your definitions of "odious" as well.

Nigelj @67 :
Agreed. Woke is nowadays an ugly term. AFAICT it started as a somewhat light-hearted label, and then was seized by the non-woke and used as an all-purpose bludgeon in the identity-politics game. The word has now become almost meaningless, other than distinguishing "them" from "us the good people".
Sad when any meaningful word loses its meaning. For example, in the USA the word "socialist" has no actual meaning for 90% of the population. It is just a bludgeon used by many politicians. Impossible to have a genuine discussion using that word, because the hearer automatically short-circuits his brain into "evil enemy ... evil enemy ... Spawn of Satan ... etc." [Shades of "1984" language-shaping, eh!] And yet the same hearer is happy to accept his farm subsidy or his Social Security cheque or his Medicare-ized hospital treatment, etcetera.
Possibly, in time, the term Woke can be rehabilitated into something light-hearted and useful . . . by overusing the word and applying it to everything in sight (and especially to right-wing attitudes & activities). By making it so greasy that it can't be grasped as a weapon.
Back on topic ~ for Twitter etcetera I would prefer to be over-censored than under-censored. Much less harm done, that way. Those who wish to have an intelligent public conversation, can find indirect ways & allusions to discuss issues (by treading a tad carefully). And the truly anti-social citizens will always continue to use their echochambers & dark spaces ~ but they won't get condoned or "normalized" in the public gaze.
To some extent, laws follow public sentiment. But the converse also applies ~ and George Bernard Shaw points out how laws can shape public sentiment, over time. Useful, to start with good laws. (Think: the Anti-Slavery laws).

Rob Honeycutt at 12:20 PM on 27 December 2022Human CO2 is a tiny % of CO2 emissions
Doug @363... "It would take little or no up front capital investment to continue with FF."
This is also incorrect. All forms of generation have a useful lifetime and eventually need to be decommissioned and replaced. What is happening is much of the new added generation as well as replacement generation is being filled with some form of renewables. Renewables are currently scaling exponentially.
Moreover, the cost of FF sources is rising as renewables continue to fall in cost. The previous link to the EIA LCOE report this year includes the cost of grid level storage since those cost are now starting to fall below the levelized cost of peaker plants.

Eclectic @66
The woke label annoys me as well, however these days Im quite happy to be labelled woke and I tend to respond that yes Im woke because I dont like bigotry and racism. Whats wrong with that? They grind their teeth about that.
I promoted the normally accepted minimal constraints on free speech, and Peppers did agree, but one gets the suspicion its with reluctance and a certain lack of commitment.
Thanks for your clear statements on the censorship issue. I have contemplated the same approach to things and I tend to agree it comes down to commonsense. However I just dont know if I trust some team at google or whatever organisation to use much commonsense. There is enormous possibility of over moderation, and of shutting down discussion and sending it onto the dark web to fester, or non moderated websites, and thus reinforcing tribalism and group think and of further alienating the conservative leaning section of society by shutting down their views. And you have people like Musk who clearly lean towards very free speech.
Our government has actually made racist speech illegal. This all well intended and I loathe racist views, but as a result some of our websites wont allow the public to post comments on articles discussing racial issues, and also issues connected to gender, presumably because they are afraid of transgressing the law by letting a bad comment slip through their moderation, or getting a lot of complaints. This is a serious unintended consequence of censorship. Some racial issues should be discussed and debated, sensitively of course.
So yeah I totally get where you are coming from, but censorship needs a light touch and a lot of commonsense.
Existing long standing laws against inciting criminal activity can be used to shut down the worst of the hate speech. Sometimes we already have the tools, and generally accepted tools but just dont use them well enough.

Nigelj @63 ,
Merry Christmas and Happy New Year ! . . . or should I more wokely say "Happy Holidays" ?
Judging by his earlier comments, "he" is clearly very much opposed to any limitations/restrictions in the public sphere [includes privately-owned media platforms]. In trying to untangle later comments of his, it still seems to me that he is emotionally attached to the idea "Four Legs Good; Censorship Bad". Outright. And, he completely steered away from debating any of my instances of the desirability of censorshipping.
Putting all that aside, I return to the ideas that:
(A) since censorship is essential in a functioning society, the real question is where the (fuzzy?) line is drawn. A difficult matter. IMO, the practical criterion/standard must be common sense. Of which there is not enough in the world. Yet a sort of committee of respectable Google employees is an example of a good start [Musk-free]. Not perfect ~ but like "democracy" it is perhaps the best we can do. ~And disagreements should be devolved to the Lowest Common Denominator level (so to speak).
and (B) there is a strong reason for censorship in the public sphere (and it is reinforced by the range and flash-fire speed of modern electronic communications). It is not that our delicate ears may be offended by statements which are unsuited to genteel Drawing Room conversations. But it is that multiplier effect which I mentioned earlier. The madness of crowds, the amplification of the more evil tendencies in human nature.
~ Whether by open statements, or by dog-whistles : the Overton Window of thoughts & actions can shift rapidly in an evil direction. (Witness recent hate crimes and recent political events.)
In other words, there should not be vastly different censorship thresholds in the various large & small social settings (public or private). Sadly, it is human nature ~ but minimal censorship produces minimal health in society. Mr Alex Jones is just one tip of a nasty & dangerous iceberg.

Bob Loblow @64,
"Shouting "my free speech was censored/suppressed/violated" if a web service refuses to allow it is not my idea of "free speech"."
I agree with you if you mean the website is refusing to allow people to post any comments at all, or refusing to allow abusive, or off topic comments. Websites are as you say privately owned and totally entitled to do that, and it doesnt suppress opinion which is the essence of what matters.
But what about the website refusing to allow comments or opinions that they just dont like, for example climate denialist comments, warmist comments, comments that promote creationism or that criticise evolution, or that express hatred, or are are factually innacurate, (eg the world is flat or covid has only killed 20,000 people globally) ? They are entitled to do that if they want, but to me that is suppressing free speech. Its intruding a long way into what opinions are allowed, and is censorship that goes right against the liberal world view. Although I might make an exception for the covid claim on grounds that blatant lies like that can fool some gullable people and end up killing lots of people.
I'm trying to get some sense of where you think the line in the sand should be drawn on moderation of what people post. I confess I'm having some trouble deciding just how far websites should go with that form of moderation, although I did try to express what I think above thread and it leans towards minimal moderation. Yes its their business if they are privately owned, but to me that is not the point.
"Shouting "my free speech was censored/suppressed/violated" when someone else says something against what you said is also not my idea of "free speech"."
Agree totally. See this all the time, unfortunately. I constantly challenge these people and point out they are confusing things and their claim is illogical.

nigelj @ 63.
...but web sites are not "public spaces". Web sites are more like publications, such as newspapers. Publicly visible for reading, but not necessarily publicly accessible for writing.
Newspapers usually invite Letters to the Editor, but very few are actually published. They may accept unsolicited opinion pieces, but few of those will make it into print. Newspapers with online material may or may not allow comments, and these may or may not be moderated. It's up to them.
"Free speech" means that someone can set up their own web page. It does not mean that any web page needs to allow any material from anyone. "Free speech" does not mean that anyone has to listen to you or pay attention to you.
Shouting "my free speech was censored/suppressed/violated" if a web service refuses to allow it is not my idea of "free speech".
Shouting "my free speech was censored/suppressed/violated" when someone else says something against what you said is also not my idea of "free speech".
Far too often, it seems that the people shouting "my free speech was censored/suppressed/violated" are really wanting to speak unopposed - they want their "free speech", but they don't want others to have the same right (whatever that "right" is). Do as I say, not as I do.
You can argue whether Twitter is a service that must accept all and everything - I raised the issue of a "common carrier" in comment #11. Web services need to be careful with what they allow and support, as they may become legally liable for material they publish. I'm not sure Alex Jones is the "free speech" model we want to follow.

Bob Loblaw at 08:42 AM on 27 December 2022Human CO2 is a tiny % of CO2 emissions
Doug @ 363:
If we accept the original premise above,
It's not a premise. It's based on measurements.
the earth is a net absorber of 17 Gigatons annually. The land having 11 Gigatons of net absorption.
So far, so good.
So more land vegetation should provide more net absorption.
In a very general sense, yes, but it depends entirely on what this "new vegetation" is replacing. Are you thinking of planting something on land that has no current vegetation, and no current soil carbon? Exactly where is this "new vegetation" supposed to appear?
The .5% is the proportion (200 million acres) of total land required to absorb the CO2 emitted by fossil fuels.
This is where you lose me. As you stated in comment 356, you determine that 15.64Gt is 3.5% of the total land uptake (450 Gt/yr in figure 1 of the OP). Your total land required still appears to be based on your 77.5 tons/acres value you provided in comment 358.
The entire land ecosystem as it stands is only capable of an additional 11 Gt/yr uptake (over and above the 439 Gt/yr it is releasing). If we created a duplicate land system covering the same area that all our current vegetation covers, it will both absorb and release CO2 just like the existing one. What is it about this new land cover that you are proposing that is different from the current one, that makes you think that we only need a much smaller area than the current vegetation covers?
New vegetation on bare soil does not have carbon uptake rates anywhere near the numbers you seem to think it does. (You have not yet provided the source of your 77.5 tons/acre number in comment 358.)

Re: Rob Honeycutt 359

So more land vegetation should provide more net absorption. The .5% is the proportion (200 million acres) of total land required to absorb the CO2 emitted by fossil fuels. I would be interested in a better analysis of this if you have one. That was the original question I presented.
Regarding your staement "it will cost less to transition to renewables than it would be to continue using FF's." That may be true for developing countries who have growing needs for power and no access to natural gas. But you shouldn't misunderstand staements that say renewables are cheaper than FF.
In the U.S. for example there is little need for added electrical power.
It would take little or no up front capital investment to continue with FF. Theoretically to totally replace The terrawatts of U.S. energy with solar and battery backup would require a $1.7trillion investment. That is no doubt not the way to proceed, but it's the cheapest renewable route.
Here's a link to eia 2020 cost of electric utilities.
https://www.eia.gov/analysis/studies/powerplants/capitalcost/pdf/capital_cost_AEO2020.pdf
For large wind turbines: base cost $1265/kw plus 35.14/kw each year
For solar PV : base cost $1313/kw plus $15.25/kw each year
For combined cycle gas: base cost $958 plus $12.20/kw each year Plus $1700/Mwhr (my estimate).
It gets complicated when you have to take into account if solar and wind have a capcity factor of 25% and 35%. So as long as we continue to use renewables with fossil backup you can just amortize the cost of renewables over 30 years and compare to FF it replaces when they're operating. If you want to completely eliminate the FF backup you have to multiply the costs of renewables by 3 or 4 and add cost of battery backup.
I don't think we should argue the economics to justify renewables. We need to argue for the benefits.

Eclectic @60, I largely agree with you, but my comment was restricted to peppers views on censoring of free speech, and he clearly does accept some limits. So its not black and white for him.
I've expalined my views on free speech in my previous comment, and that limits should be fairly minimal in public doman places like websites. Would be interested in your feedback on that even if you violently disagree. If you have a spare moment. I'm wrestling a bit with the issue because free speech is important, but the internet has turbo charged the spread of misinformation and this is very bad news. Reconciling the two is not looking easy.

Charlie_Brown at 07:45 AM on 27 December 2022From the eMail Bag: the Beer-Lambert Law and CO2 Concentrations
Scruffy @29
Bob’s example illustrates the concept of a diminishing effect of increasing CO2, but as I challenged in @1 and Bob agreed in @2, it is insufficient to fully explain the complexity of the saturation effect. I prefer using the figure that Bob @7 reproduced from SpectralCalc.com for me to explain the saturation effect not as cylinders or cells in series, but as absorption lines (absorptance = 1 – transmittance) in parallel where strong lines reach an absorptance of 1.0 at low CO2 concentrations while weak absorption lines contribute to increasing absorptance with increasing concentration.It is much better to interpret the Beer-Lambert Law by looking down at the atmosphere from space than it is to look up from the surface. The common view of Beer’s Law considers attenuation of the energy emitted from a surface. For example, measure the energy emitted from a source, travels through gas such as CO2, and reaches the end of a cell. The NIST spectrum provides the results for the specified set of conditions using this approach. However, the energy that reaches the end of the cell from the original source does not include re-radiated energy. That is because IR absorbed by CO2 in the cell is re-radiated in all directions, mostly to the cell walls where it is absorbed by the cell walls. The geometry of the measurement cell, unlike the open atmosphere, precludes re-radiated energy.
You say “NO energy will be radiated into space in the CO2 absorption spectra - that atmosphere is completely opaque at those frequencies.” This should be clarified to say that none of the original source energy (photons) from the surface will be radiated into space because it will be absorbed and re-radiated along the path length toward space. However, all molecules above absolute zero vibrate and radiate energy. CO2 at all levels of the atmosphere will radiate energy. At the uppermost atmospheric layer containing sufficient CO2 molecules, energy radiated by CO2 will radiate to space in the CO2 absorption band, precisely because absorption lines have a value great than 0. Kirchhoff’s Law provides that absorptance = emittance (with the caveat of being at thermal equilibrium, which allows for energy transfer between molecules by collision or conduction in addition to radiation.)
Bob’s experiment in the original post demonstrates why it is better to view the effect of Beer’s Law on radiant energy escape to space by looking down from space. The atmosphere in the tropopause at an altitude of about 10-20 km is thin and cold. There is a lot of distance between CO2 molecules. The key is that there is a very long path length available, sufficient to bring many of the absorptance lines in the CO2 band to 1.0. With increasing CO2 concentration, even the absorptance of very weak lines becomes significant.
Your description of the overall global heat balance is incorrect. Increasing CO2 will cause more heat to be absorbed closer to the surface, and this will lower the temperature of the tropopause. This is part of a special and complicated signature of global warming by CO2. It actually reduces emittance to space, aggravating the greenhouse effect rather than offsetting it. The greenhouse effect is driven by the temperature profile of the upper atmosphere. What happens in the troposphere below the tropopause, including convection, conduction evaporation, and condensation, just moves heat around within the troposphere. You mention the effect of water vapor, which also exacerbates global warming as a positive feedback effect. The role of clouds is complicated. High, cold cirrus clouds can increase warming while low, warm, thick clouds can reflect solar energy. All of this is discussed in detail elsewhere, and is beyond the scope of a single rebuttal. But if you have any more specific questions that are stumbling blocks for your understanding, I will try to address them as succinctly as possible.

nigelj:
The problem with reading between the lines in Peppers posts is that you can find bits that show him sort of agreeing with those reasonable controls, but then he posts additional stuff that sounds like it comes from a point of "everything is fair game" viewpoint. Add in a few bits that look like "everyone's opinion is as good as any other, and there is no right answer" and it looks like an apologist's perspective on defending the behaviour you think he (Peppers) agrees is wrong.
There is a tremendous inconsistency in Peppers' stated positions. He uses "free speech", "censorship", "woke movement", "cancel culture", and similar terms in exactly the sort of pejorative dog-whistle style that is toxic for reasonable discussion. I am willing to entertain the possibility that he does not realize he is doing this - but he really needs to sit back and think about his position(s) and how to choose to communicate them.

Bob Loblaw at 07:11 AM on 27 December 2022Water vapor is the most powerful greenhouse gas
Prof Nazar:
Are you trying to claim that there is no experimental evidence that CO2 will absorb IR radiation at certain wavelengths?
Are you trying to claim that the amount of absorption does not vary with CO2 concentration?
If so, then why is it that I can buy commercial off-the-shelf technology that measures CO2 concentrations in air using those principles?
Are you arguing that the absorption of IR radiation by CO2 does not increase the energy level of that CO2 molecule? And thus the average temperature of the air?
If so, you are taking a position that does not respect the conservation of energy.
If you are just saying "I haven't seen anything that convinces me", then you are probably making an Argument from Incredulity.
You are long on assertions, and really, really short on presenting any actual evidence for your assertion.

There hasn't been a single experiment comparing temperatures of infrared transparent airtight capsules with different CO2 concentrations, including on with current-atmosphere concentration... also, comparing with different infrared filters in the "crystal" and heights, so where's the real falsifiable science? It's all based on assumptions without being able to discriminate confounding variables!

Guys, I agree with you on most things, but you might be misinterpreting what Peppers is saying on free speech. The trouble is his stuff is a bit opaque. Just have a closer read and read between the lines.
I believe hes saying he is strongly in favour of free speech in the public domain but he does accept some limitations / censoring, such as laws against inciting criminal activity, defamation law, and moderation policy forbidding name calling, off topic and spamming. He is pretty obviously saying keep limitations very minimal, and dont censor peoples opinions even if they are crazy or a bit unpleasant. I dont want to have to speak for others like this, but it needs something to stop things going off the rails. Although all individual comments are interesting to me.
I'm inclined to agree Peppers on the free speech issue (but not much else). Free speech seems very fundamental and having too many limitations on free speech is a big problem. Facebook and Twitter have tried to eliminate misinformation and so called hate speech, and they mean well but it needs an army of people and could easily be abused to delete content they simply disagree with. George Orwells novel 1984 sums up the problem perfectly.
Its better to have the nonsense largely out in the public domain where it can be debunked. Maybe with a few exceptions that are life threatening (promoting that "covid is harmless"). I can accept censoring that sort of thing if experts are saying it and so could be taken seriously.
And nobody has to host sub groups like 8chan devoted to obvious and blatant denigration of minority groups that is bordering on inciting violence. A bit of commonsense does come into it.
This websites moderation policy seems pretty good and sophisticated, and its limits on speech are fairly minimal and appropriate. People are also given plenty of warnings.
Quite willing to change my view if anyone can convince me with sensible reasoning.

Doug @358 , please show the general outline of your back-of-envelope calculations. There are numerous important factors applicable to your scheme.
For instance ~ and I know you did not mean it that way ~ your 240 years of coal/oil , multiplied by your 0.5% of total land mass . . . comes to 120% of total land area. Interesting !
But seriously, Doug, when you look at Canadian/Siberian tundra, and at semi-deserts (etc) . . . there is almost zero scope for major forest development (being land which is incompatible with high-carbon plants i.e. trees). And afforestation elsewhere, would mean replacement of crops which do ultimately produce human food. Not to mention 8 billion citizens revolting in the streets as you attempt to enforce a vegetarian lifestyle.
Yes, you should buy lithium-mining company shares at present. But battery technology is advancing very rapidly ~ and there is no shortage of sodium, aluminum, etcetera.
## Please show your workings, Doug. Including the effective average number of years for a forest to reach maturation/stasis (regarding carbon uptake).

Bob Loblaw at 06:12 AM on 27 December 2022Human CO2 is a tiny % of CO2 emissions
Doug Cannon @ 358:
Where do you get your 77 tons per acre number from? Is that tons of carbon, or tons of CO2 equivalent? And since you are using acres, is that an imperial ton, rather than metric?
I am fairly familiar with forest carbon cycles in the boreal forest, and 77 tons per acres is close to 200 metric tonnes per hectare, which is a reasonable number for entire ecosystem carbon in the boreal forest. But this includes tree biomass, root biomass, leaf litter, dead branches, and soil carbon. And soil carbon (in the boreal forest) is often as much or more than the tree biomass. And this ecosystem carbon does not accumulate in a day, or a year, or even a decade - we're talking centuries-old ecosystems.
Please explain your calculations, and give us a rate of carbon uptake per year. Then you can compare it to annual fossil fuel emission rates. Then you can calculate how much area is needed to offset current emissions - and then how much area (and time) is needed to suck out the CO2 we've already added over the past century..

Peppers @ 51: "Online is out in the street."
To begin, this is clearly wrong on several fronts.
- The Internet is not publicly-operated. People pay their ISP to get access, or get it for "free" from commercial establishments that build the cost into the products they sell.
- Most web sites, social media platforms, etc. are not publicly-operated. Each business or private entity that chooses to place information or a discussion forum on-line gets to choose what sort of open discussion they are willing to allow. They may choose to not allow any public commenting at all. They may choose varying moderation policies, such as "all comments will be moderated before being made visible". People may or may not have to register. SkS chooses a system where users must register, comments go live immediately, but are subject to moderation after the fact, as outlined in the Comments Policy.
- No "online" resource is forced to allow anyone to say anything they want, whenever they want. It's closer to "freedom of the press" - a freedom granted to anyone that has the money to own a press. Try walking into your local paper with your manifesto and demanding that they print it for you in tomorrow's paper. Please take a video of them laughing their heads off and post it to Youtube where we can all get a laugh.
Even if "online" was like "out on the street", nobody has the freedom to walk around saying anything they like to anyone they like wherever they like. I"ve previously mentioned libel and slander laws. I will now mention "public nuisance" laws. If your behaviour (even just spoken word) significantly affects the enjoyment of public spaces by others, you will be subject to legal restrictions.
I live in Canada. The relevant statue is in the Criminal Code, Causing disturbance, indecent exhibition, loitering, etc. Quoting in part:
Every one who
- (a) not being in a dwelling-house, causes a disturbance in or near a public place,
- (i) by fighting, screaming, shouting, swearing, singing or using insulting or obscene language,
- (ii) by being drunk, or
- (iii) by impeding or molesting other persons,
- (b) openly exposes or exhibits an indecent exhibition in a public place,
- (c) loiters in a public place and in any way obstructs persons who are in that place, or
- (d) disturbs the peace and quiet of the occupants of a dwelling-house by discharging firearms or by other disorderly conduct in a public place or who, not being an occupant of a dwelling-house comprised in a particular building or structure, disturbs the peace and quiet of the occupants of a dwelling-house comprised in the building or structure by discharging firearms or by other disorderly conduct in any part of a building or structure to which, at the time of such conduct, the occupants of two or more dwelling-houses comprised in the building or structure have access as of right or by invitation, express or implied,
is guilty of an offence punishable on summary conviction.
If Peppers truly believes that "free speech" gives people absolute freedom to speak, how would he react if he and his family went to a public park to have a picnic, and someone came up with a megaphone, started hurling insults and obscene taunts at him and his family, drowning out their attempts to have a nice family conversation, then followed them to the parking area as they tried to leave, followed them home, continued to hurl insults at them from public space in the street. etc?
To try to get back on-topic, the original post is about SkS considering its options with respect to participating in Twitter or not. Elon Musk paid $44B so that he could get to make the rules for his on-line social media site. Elon Musk has made claims about wanting a forum where "free speech" is allowed. What things has Elon done to make this so?
- Banning journalists for questionable reasons, and then imposing conditions for their return.
- Threatening to ban links to other social media sites.
It certainly sounds like Elon wants "free speech" for some, but not "free speech" for all. Well, it's his company, his rules. But Apple is not infringing on Elon's "free speech" rights if they decide they do not want to do business with him.
And it is perfectly reasonable for SkS to question whether they want to be part of Twitter.

Rob Honeycutt at 04:53 AM on 27 December 2022Human CO2 is a tiny % of CO2 emissions
Doug @358, 356...
It's my understanding that vegetation is both an absorber and emitter of CO2. So, just increasing vegetation by a small fraction isn't going to do much to change the overall balance. There certain is some sequestation, so it's a good thing to do, but it would take far more than a 0.5% change to offset all human emissions. And, in fact, we are currently operating in the opposite direction with deforestation in important places like the Amazon. So, we'd need to first reverse that, and then reforest from there.
Regarding, "[a] lot of money dependent on renewables and EV's," it's not exactly clear what you mean by this. Wind and solar are now cheaper than all fossil fuel sources, so it's actually cheaper to replace retiring FF energy with clean energy free of carbon emissions. Ostensibly, these means it will cost less to transition to renewables than it would be to continue using FF's.

The right to speak hasn't changed. You are still fully in your right to say anything you like, but likewise, people are free to criticize what you say. And if you say something people find offensive or damaging on their property or in their online forums, they are free to have you removed.
The only thing that has changed in recent times is that people using hateful language and conveying gross misinformation believe they should be immune from criticism. And that's just not how it works.

Eclectic @357
I find it hard to believe that the earth is at its maximum capability of supporting vegetation and couldn't increase it by 3.5%. Since 1960 we've improved land use to a level equivalent of over 3 Gigatons of CO2 annually.
I had done some estimates. Based on an average absorption of 77.5Tons per acre we would need an additional 200 million more acres. That's a little over .5% of total land mass. Not an easy task but certainly a reasonable target.
Even if we couldn't totally balance existing fossil fuel emissions we could make a pretty good dent. Maybe even enough to forego the need for battery back-up on a scale necessary for electric power generation. Hopefully we could get a capacity factor of close to 60% with a combination of wind and solar and only need 40% of existing fossil for electricity. (Then incentives for non plug-in hybrids could delay the downside of all-electric vehicles, which would otherwise delay the decommissioning of coal fired electricity.....but that's an issue for another day.)
I realize there's lot of money dependent on renewables and EVs which would make any such strategy unpopular with much of the investment and media community. But we're not getting far with the current approach of big meetings every few years to lie about goals with no plans.
Not to worry about running out of fossil fuels. We have over 240 years of known reserves at current useage (coal-139, oil-54, natural gas-49). We'll run out of lithium before fossil fuels.

No one is doing that. What seems to be the issue for those complaining of "woke" and "cancel" culture is that people are criticizing your opinions. Thus, what I'm saying is, this isn't about free speech, per se. It's that some people want the "freedom" to say awful things without criticism. And that's not how free speech works.
Free speech is a double edged sword. If you want the freedom to speak how you wish, you have to accept others speaking as they wish in response.

@53 Peppers ~ you are under a severe misapprehension.
There has never been a human society with a broad "right to speak" (in the sense you mean: of unrestricted broad freedom). You are imagining a Golden Age which never actually existed.
Not even in the micro-society of your own household is there an unrestricted freedom to be abusive/ insulting/ threatening/ demeaning, etcetera. Or if your household does indulge in such behavior, then I confidently predict an early demise of the household.
No "broad right" in the time of Socrates or Cyrus, or in any century before or since. Not even in the time of Jefferson or Lincoln, Eisenhower or Bush snr. Every functioning society has restrictions ~ restrictions applied through good laws and/or bad repressive laws, through politeness or customary etiquette, or through plain old common sense and decency.
Peppers, you are out of touch with human reality. Please come down to Earth, and have a major re-think of your opinions.
Twitter and free-speech/censorship are very much the topic of this thread. The Original Post said it well, though narrowly. IMO it is the right decision for Twitterati to stay on Twitter and continue to fight the good fight . . . preferably without investing a debilitating amount of effort. Conceivably, the pendulum will eventually swing in a healthier direction sometime in the future. [Post-Musk!] Mastodon deserves to thrive, but may not be able to achieve the more universal usefulness of Twitter.

Eclectic at 12:05 PM on 26 December 2022Human CO2 is a tiny % of CO2 emissions
Doug Cannon @356 ,
Before pursuing that idea of CO2 control by increasing mass of vegetation, it would be worth doing some back-of-envelope estimations. Potential increased tonnage of woody plants (and carbon content) per square km, as well as carbon in soil microbes/fungi . . . and where these requisite vast areas would go. And the ongoing supply of phosphates & other nutrients. And the continued increase needed. And the cycle of rotting. You might be unpleasantly surprised at the impracticalities involved.
Seaweed/algal stimulation by distributing iron salts over the pelagic ocean has been suggested . . . but failed to show practicality.
Simpler quicker & cheaper to use wind /solar /nuclear solutions ~ which we will have to do anyway, as fossil fuels run out.

Doug Cannon at 07:33 AM on 26 December 2022Human CO2 is a tiny % of CO2 emissions
I realize the article is out of date but I believe my logic would hold for 2022 as well as 2007.
The increase in ppm CO2 in the atmosphere by 2 ppm each year is pretty constant. That amounts to an additional 15.64 Gigatons per year. That's in the ballpark of the 60/40 split for absorption.
Ignoring the ocean absorption, that 15.64 Gigatons is 3.5% of the absorption over land. I'm wondering whether increasing vegetation/forest/etc. by 3.5% would hold atmospheric CO2 ppm constant. Then stretch that to 10% and we can forget about CO2 absorption plants. It seems more elegant than diverting trillions of dollars to renewables and batteries.

That was not the angle of the topic. In your sense, yes you can. There was a prior post about harm and retraining folks not agreeing, etc.
The only thing I would add would be about being welcoming to new posters. Its frustrating to hear the same ole, over again. But generally newly in's will bring those. And it will feel like work to repeat it all, but you may convert more. This is a small point.
And I have just said its best to close. There is a lot of disagreement around free speech Im surprised to find. Maybe there isnt as broad a right to speak anymore.
We recently heard about some peoples calling something foreign disinformation, censoring it and falsely advancing their group. I thought that was cheating and they were acting badly. They quelled free speech. Maybe this is just ok now and thats the new baseline. I hope to always hear the truth here.

What you fail to understand is, that we can make rules for what can be posted as comments on our website, it's called the comments policy and when you and others registered you agreed to abide by it. One of the rules states:
No sloganeering. Comments consisting of simple assertion of a myth already debunked by one of the main articles, and which contain no relevant counter argument or evidence from the peer reviewed literature constitutes trolling rather than genuine discussion. As such they will be deleted.
So, we expect commenters to make sure that they are not simply repeating already and long-debunked myths about human-caused global warming before posting a comment. If they still do and we delete the comment, it's not censoring by any stretch of the imagination and it's also not an infringement on the commenter's right to free speech as others have already pointed out. Our website, our rules. Nobody is forcing you to post comments here after all.
As a general aside: We also have a rule for "All comments must be on topic." and I'm not really sure how many of the comments posted in this thread are actually on topic as far as our Twitter & Mastodon involvement go. How about calling it quits instead of running - or posting - in circles?

Free speech is important here as it is how you can deliver your message. Labeling an opposing message to your own thought as 'harmful misunderstanding' removes the usefulness of this site and your mission.
I'd think you would want to welcome them in, hear once again the same issues all newcomers bring and try and convince them. Not silence them. Here is the list of narrow exceptions to free speech:
Rights, against
To incite imminent lawless action. ( child porn?)
Brandenburg v. Ohio, 395 U.S. 444 (1969).
To make or distribute obscene materials. (or maybe here)
Roth v. United States, 354 U.S. 476 (1957).
To burn draft cards as an anti-war protest.
United States v. O’Brien, 391 U.S. 367 (1968).
To permit students to print articles in a school newspaper over the objections of the school administration.
Hazelwood School District v. Kuhlmeier, 484 U.S. 260 (1988).
Of students to make an obscene speech at a school-sponsored event.
Bethel School District #43 v. Fraser, 478 U.S. 675 (1986).
Of students to advocate illegal drug use at a school-sponsored event.
Morse v. Frederick, __ U.S. __ (2007).The point that is really my business, is that free speech does not include labeling something something else on the delete list so you can cancel it.

Peppers @40...
I don't know how more clearly to state this. "Free speech" only means that Congress cannot enact laws that limit what you say. Everyone else is fully in their individual rights to limit what you say with respect to their own properties and businesses.
If someone is asking you to leave their home or business because what you're saying, that is not a limit on your right to free speech. It merely means they're telling you you've stepped past the bounds of what they are willing to listen to. You are free to find another venue for what you want to say.
What you're asking for, as far as I can summize, is the "right" to say awful things and not be criticized for it. And that's not how it works. Congress cannot enact laws that prevent you from saying awful things, but your fellow citizens are fully within their right to ostricize you when you do.
What you're complaining about with "woke" and "cancel" culture is merely politically motivated labeling. It's linguistic framing designed to literally do what you're complaining about others doing.
You want free speech but don't want to allow others the freedom to exercise their right to free speech in their criticisms of what you say.

you are using free speech to denounce free speech. You would miss it if gone.
the comparisons to physical harm to protect against speech does not equate. Someone promoting child harm would not fare well. Not a likely example either but you are trying to make a point, albeit extreme for a fast gain. You are using free speech.Bob yes you could call those labels. They were identifiers I thought and not as global as 'harm', but I may end up labeling too. I must have been implying negative to cite them and then my premise would have me ask, mwas I qualified to label cancel culture as a negative culture? And I was a I'm saying to not let people say their piece is a mistake. Goose and gander applies.
in addition to this site and this article, there are matches in opposition to equal it.
this Is historic. The second time in history a global issue has come to us. But this is worse. atom bombing involved deterring and withholding. This has been done and it is about containing. Even dreams of reversing. Every mock, every poke, every diminishment of one another makes me feel further from home, as Tom Hanks said in Private Ryan. Every attempt to force or bluster this through is not working and I don't know how to convey it except to display and convince and hopefully convert. The forum is free speech For that. minimizing What you don't want to hear has one minimizing what you came to get. New ones to your message.

Bob Loblaw at 00:37 AM on 26 December 2022From the eMail Bag: the Beer-Lambert Law and CO2 Concentrations
Scruffy:
As the article makes no mention of CO2, nor the length of the cylinders, when discussing the 1% per cylinder, 37% for 100 cylinders example in figure 4 and related text, your criticism of those numbers is a straw man argument. The example shows the exponential nature of the absorption relationship, and you are reading more into it than it says.
You do not explain what "NIST data" you are referring to. NIST is not mentioned in the blog post.
As for the rest of your comment, you have missed an extremely important factor. You speak of CO2 molecules absorbing IR radiation and transferring energy to other molecules. You seem to be completely unaware that the same process of molecular collision will add energy to CO2 molecules and allow them to continually emit IR radiation at the same wavelengths that CO2 absorbs IR radiation. Your conclusion that "no energy will be radiated into space in the CO2 absorption spectra" is simply wrong. For it to be true, CO2 molecules would need to drop to a temperature of 0K, which won't happen as long as they can collide with other molecules (of other gases) and maintain a tempesrature above 0K. In fact, they'll be at a temperature equal to those other molecules.
The bogosity of your argument is also made clear by your claim that other greenhouse gases can emit IR radiation "in their own spectral lines", and pass energy up through the atmosphere - energy that they received by collision with CO2 that absorbed IR radiation. This magical thinking requires that other gases follow different physics from CO2 - they can emit IR radiation, but CO2 can't. Standard physics does not claim that CO2 is the only gas that matters - it just accepts that all greenhouse gases can both absorb and emit IR radiation in the spectral lines that match their internal energy state levels. And that collisions are constantly transferring energy from one molecule to the next - in both directions (not just one, as your hypothesis requires).
You clearly do not understand how greenhouse gases play a role in atmospheric energy transfers.
-
Scruffy Scirocco at 23:24 PM on 25 December 2022From the eMail Bag: the Beer-Lambert Law and CO2 Concentrations
Useful article, but the example doesn't accurately reflect CO2 absorption. The example states that if you lost 1% of your energy through absorption in each cylinder, you would still have 37% of your ebergy after 100 cylinders. This is correct. But CO2 absorbs energy far more efficiently than that. Using the NIST data, the transmittance is only 30% through a 10cm path at 200mmHg. It's losing 70% of its energy, not 1%.
Granted, 200mmHg is far more CO2 than the atmospheric .300 mmHG of CO2 we're dealing with, but this means that an equivalent "cell" of absorption at 1 atmosphere with 400ppm CO2 would be 65.8m. After only 5 such "cells" you would have lost 99.76% of your energy to absorption.
We can discount re-radiation passing energy forward, as that's accounted for in the NIST measurements. The lost energy will be converted to heat, which will then conductively transfer to the other 99.96% of the gasses in the atmosphere, which will pass the energy upwards in their own spectral lines.
NO energy will be radiated into space in the CO2 absorption spectra - that atmosphereis completely opaque at those frequencies. Adding more CO2 won't change that. The idea that adding CO2 will change the characteristics of the re-radiation as it goes up the atmospheric column assumes that CO2 is the only gas, and that other gasses won't be conductively robbing the CO2 of the heat it's absorbed.
What WILL happen as CO2 levels increase is that the heat absorption will occur closer to the surface, causing an apparent increase in temperature, but this is offset by cooler temperatures at altitude, not accounting for convection and increased oceanic evaporation, which, while increasing the water vapor in the atmosphere (Major greenhouse gas) will also increase cloud cover and thus surface albedo, lowering the surface temperature of the ocean. -

Peppers @44 ,
Your argument fails. Intellectually and morally.
The rhetorical quote you give, about the man: "advocating at the top of his lungs that which you would spend a lifetime opposing" ~ is an example of a fine rhetorical piece which, at first encounter, seems nobly liberal & almost Voltaire-like.
But further thought shows the piece to be absurd. And absurd, because in a civilized society there must be limitations & restrictions of extremes.
Peppers, I am confident that both you and I are strongly opposed to the abduction of children for organ-harvesting and/or torture. Yet if the shouting man were advocating such immoral activities ~ would you be nobly prepared to defend his free speech "rights"? (A rhetorical question, of course!)
And assuming you do not favor severe child-abuse ~ what happens if the shouting man were not actually advocating such crimes . . . but were merely advocating de-criminalization of these activities? Where do you draw the line, Peppers? Your argument so far has been that you strongly disapprove of drawing any line anywhere which could limit "free speech".
In short, your "free speech" position is absurd. So absurd, that I rather suspect you have been filling an idle hour or two with disingenuous nonsense. But no need for that, my friend ~ there is already enough and to spare, of nonsense on the internet. Why would you wish to add more?

HI Charlie Brwon,
I dont think folks grappling or struggling with info, new to them, constitutes harmful information. Asking questions and trying to understand should not. And I maintain that labeling as harmful is a method to diminish the other, under the presumption that your opinion and/or conclusions are tantamount. You are challenged with that tack, to presume you have the last word as you also know new information may still arrive and could matter.
I am not trying to affect anyone else, but trying to figure this out a bit myself.
For something specific, I have not seen much detail in to the increase in human population from 1B in 1900 to 8B this year, yet it has an identical graph line for our Co2 increase. Not the 'humans breathe within the cycle' response. But the increase of consumption and giant leaps in fuel uses. 90.72% of this 8B have cell phones bankmycell.com. So where do these people in the somalian desert charge their phones? Because apparently almost everyone has one. Each and everyone of them also wants a car, because they are like you and I. As tech becomes more efficient, more can access one, more on the road and no gains are made. This could be very relevant as current GW reports are that no gains are being made.
My point is not about cell phones or breathing Co2 being net, but that defining the reason the increase has happened will dictate where to aim the guns. Oil gas and coal are just fulfilling demands. Our rocketing from 1 to 8 billion consumers is not talked about.
I am thinking about this, and other concerns. In what way am I being harmful to you?
Thx D

I was certain we were close on our understandings. What differences remain are what will be mine as an individual.
Id like to repeat a partial of what I inserted before, from movie American President and can be utubed.
"You want free speech? Let's see you acknowledge a man whose words make your blood boil, who's standing center stage and advocating at the top of his lungs that which you would spend a lifetime opposing at the top of yours. You want to claim this land as the land of the free? Then the symbol of your country can't just be a flag; the symbol also has to be one of its citizens exercising his right to burn that flag in protest. Show me that, defend that, celebrate that in your classrooms. Then, you can stand up and sing about the "land of the free".
