John Hartz, you are kidding, right?
Through moderation, this site is shielded from commentary by climate deniers, but try to write anything about climate science on any unmoderated forum and see the mountains of nonsense you have to put up with.
Climate deniers have had so much impact that they have effectively prevented any worthwhile political action on climate change for about three decades.

ed56 @19,
People who resist expanding their awareness and resist improving their understanding and resist applying what they learn to help develop a sustainable and improvable future for a robust diversity of humanity fitting in to a robust diversity of life are not "... natural grown inhabitants of this planet".
They are products of the socioeconomic-political systems and story-telling that they developed in. They are humans who have allowed their ability to be 'helpful members of a robust diversity of humanity' to be over-powered by the 'harmful selfish enticements and motivations of the socioeconomic-political systems' that can be seen to develop harmful unsustainable results and develop powerful resistance to correction.
Climate science and the resistance to accepting it is clearly the largest case study proving that point. But similar examples exist related to every other Sustainable Development Goal.
Whenever the harmful correction resistant portion of the population sense that learning would threaten a developed belief and resulting personally liked actions they will be tempted to use all available methods to evade 'learning to be helpful rather than continue to be enjoy being harmful'. That is on bold display everywhere. It is even tragically succeeding at temporarily winning unfettered power in some of the 'supposedly most advanced nations'. And it is having significant influence even if that harmful portion of the population do not win unfettered power. Popularity and profitability are hard to effectively fight against.
The future of humanity is at stake. And there are indeed two camps. And one of them clearly deserves to be Governed and Limited by the Other Camp. The Nature and Humanity camp must govern and limit the Popularity and Profit Camp.

OPOF, you seem to be quite happy to defend the indefensible. AOC saying "the world is going to end in 12 years if we don't address climate change" is not defensible at any level. The statement is wrong on its face. We really don't know what she actually meant and it doesn't matter. The climate denying blogosphere predictably got great mileage out of it. And, hopefully, if AOC had her time back again, she would not have fed them this goldmine quote. But she won't learn any lesson from this incident if she keeps her head in the sand and brushes it aside as obvious exaggeration as you have done.
On the other hand what did you mean by the following:
"And very few reporters who started piling on to the original misleading claims about what Mann said appear to have bothered to actually better understand the issue before piling on (potentially including Potholer54)"
I know you don't like the guy, but what does "potentially including Potholer54" even mean? If he actually did pile on Mann then you need to link to where he does so and not just say that you think he might have done so if he had thought about it or whatever else you meant by that statement.
Potholer's latest video now has over 40,000 views and over 2,300 comments. Climate Adam's video is now dead in the water. You might not like his style but he is having a significant effect here.

Here is even more independent confirmation that the rate of sequestration is reasonable and repeatable.
Soil Carbon Sequestration and the Soil Food Web
First a simple video made by Dr. Elaine Ingham explains what I have been posting about here for several years. Including the same rate of sequestration found all over the world well within the 5-20 tonnes CO2e/ha/yr found by Dr Christine Jones decades ago and confirmed by many others.
And now Dr David Johnson tosses his hat in the ring as yet another independant researcher obtaining results in this same range.

Nigelj, science denial may be a special problem in den US (much less in Europa, where I sit), but then again it is not a challenge for natural science.
It may be one for sociology, and I miss information here from this perspective.
You all know better what the effect of this website is, from my superficial perception it could have the effect of further splitting the (social) camps.
Remember, the other camp is also a natural grown inhabitant of this planet ;-) -
One Planet Only Forever at 02:15 AM on 8 December 2019Video: Is CO2 actually dangerous?
nigelj,
Trying to be brief, clear, attention getting, and unable to be misinterpreted is very hard.
Even warning about the end of the world "as we know it" does not say what needs to be said.
If "all of the SDGs, but especially the Climate Action Goals, are not achieved by 2030 and improved on after that time", humanity will have a much tougher time developing a sustainable future that can be improved by new sustainable developments.
The world humanity developed in is already irreversibly negatively affected in many ways. And lack of action towards achieving all of the SDGs by 2030, and improving on them all, makes it worse.
We are already seeing extinctions of life forms as a result of the harmful unsustainable ways of living that the current fatally flawed developed socioeconomic-political systems encourage because popularity and profitability are claimed to be "Irrefutable Proof of Good and Deserving". And the climate change tipping point of one of the Antarctic Ice Sheets has already been passed.
The robust diversity of life for a robust diversity of humanity to sustainably be a part of is being irreversibly damaged. And a very slow changing physical planet has also been irreversibly impacted by sped up changes.
The Harm of CO2 from fossil fuels is a by-product of the harm of human competition for perceptions of superiority relative to others. The developed systems, especially ones that measure merit by popularity and profitability but do not effectively limit what is allowed in the competition, are "the world as we know it" that actually needs to be ended by 2030, the sooner the better.
Actions that are likely to be sustainable should be the only actions allowed to compete. And if new learning identifies that an action is not as sustainable as originally thought, a good system would rapdly shut it down, not caring about how popular or profitable it was, and not caring to 'protect the perceptions of wealth that had been developed'. That was done with MTBE (google it). But it is essential for the system to care to make sure everyone is helped to rapidly transition to a sustainable way of living as the developed unsustainable action is very rapidly terminated.
Correcting the massively incorrect system and its current day developments means a lot of people who perceive themselves as winners actually have to admit they are 'less deserving' and need to change how they live and be more helpful to others as they give up personal benefits.
Try to say that briefly. It is what the SDGs and the GND are all about. But it cannot be 'stated briefly'. And more careful communication of climate science will not do it.

MA Rodger at 20:05 PM on 7 December 2019CO2 was higher in the past
Livinginawe @98,
You pose an interesting thought (which I think can be addressed on-topic).In essence, I don't think mankind's could ever become saviour of a living world by boosting atmospheric CO2 levels.
If we look tens-of-thousands of years into the future, there is talk (eg see this Wikithing page, although the reference it makes Berger & Loutre (2002) is not as defininte) that in 50,000 years time the world will face an ice age that will not be dodged by our emissions. By that time the impact of our emissions on the atmosphere would be much diminished. But an ice age does not of itself reduce the amount of carbon about. Rather it sucks it out of the atmosphere into oceans and frozen soils.
While these dips in CO2 could soon make life for C3 plants very difficult, C4 plants can survive at atmospheric CO2 levels well below 100ppm. And there are also aquatic plants which maybe even benefit from colder waters enriched by CO2.Over the longer term, hundreds-of-millions of years, the increase in solar strength will increase rainfall and thus increase rock weathering drawing down carbon into the geology via the slow carbon cycle(as this NASA web-page terms it) while the release of carbon back from geology via volcanic activity is presumably fixed and will not respond enough to compensate. Thus the 60,000Gt(C) on the planet will more-&-more become trapped in the geology (currently about 10,000Gt(C) is in trapped in rocks) and atmospheric CO2 levels will drop.
The works of man so-far have release ~700Gt(C) from FF with perhaps 1,500Gt(C) of FF reserves and so they don't amount to anything significant in the grand scheme of things.
Mind, as the sun warms the planet creating a wetter world which draws down more CO2 into the rocks, that loss of CO2 will cool the world and act as a brake on the process. The loss of CO2 would be something like 500My of the strenghening sun, so after that sort of time period the wetter climate would have no CO2 'brake'.Over the last 50My we have seen atmospheric CO2 levels drop but that atmospherc loss of perhaps ~5,000Gt(C) was probably driven by the Himalayas being weathered down in the wet climate of the tropics with a feedback of lost CO2 cooling the climate and drawing further CO2 into the oceans (where most of the planet's carbon resides today). So the rate of loss of atmospheric CO2 over the Cenozoic era probably shouldn't be projected into the future with any confidence.

Regarding "Flat Earthers, and the Rise of Science Denial in America," linked by John Hartz.
A good read with mostly convincing conclusions, but it was not clear what it meant by denialists. I think what you have is "hard core" denialists who have gone slightly crazy and have a very extreme view of climate science. There are many moderate sceptics who are just slightly sceptical and people who are rather "impressionable" and easily swayed. The risk is the hard core denialists infect these moderates. This is the war zone we have to be wary of.
These are two largely different groups, because we are all sceptics of everything to some extent. Facts wont change hard core denialists minds, with a few exceptions, because they are driven by ideology and conspiracy theory beliefs, but I believe facts do change the minds of the moderatly sceptical people. The article failed to make the distinction so sends a bad message.
Sadly the article was also rather vague on just how to reach the hard core denialists but rather than throw too many facts at them it might be useful to talk about motivated reasoning and confirmation bias. Thus they are not being told they are wrong or have the wrong facts. But the rest of the article was great.
These denialists seem to go over board with conspiracy theories and they really do "believe". I remember reading about the illumaniti conspiracy and it can be seductive, but I have a big internal wall that stops be falling for this sort of thing, and a careful study of the origins of the group shows its harmless. But that sort of study takes effort to find reliable information and recognise it. Makes me wonder if denialists are often just lazy.

One Planet Only Forever at 12:59 PM on 7 December 2019Video: Is CO2 actually dangerous?
nigelj @ 34,
I share your experience as an Applied Science Professional seeking justification for any claim or decision made (and trying to make sure my claims or decisions had a robust basis). My most common move regarding a claim was to ask the claim-maker (Sales-pitch deliverer) to provide a clarification or more detailed justification and independently investigate the issue.
That led me to challenging "technical Sales Reps" in ways that resulted in them changing their sales pitches. In some cases they realized they had been caught making a claim they could not defend and they changed.
To be as correct as possible here is what Mann said:
"A runaway greenhouse effect means once the planet gets warmer and warmer, then the oceans begin to evaporate. And water vapor is a very strong greenhouse gas, even more powerful than carbon dioxide. So you can get to a situation where it just — the oceans will begin to boil, and the planet becomes so hot that the ocean ends up in the atmosphere. And that happened to Venus."
And many years later some people, including the infamously incorrect Watts of WUWT, started claiming Mann had incorrectly declared the "End of the world". And very few reporters who started piling on to the original misleading claims about what Mann said appear to have bothered to actually better understand the issue before piling on (potentially including Potholer54). Few if any appeared to ask Mann what his comment or clarification was. And nobody asked the originators of the misleading claim making like Watts to explain themselves (just like few, maybe nobody, are asking the misleading climategate claim-makers to explain themselves).
The same thing happened to AOC and her "End of the World" remark. AOC was most likely correctly commenting regarding the need to achieve all of the Sustainable Development Goals by 2030, not just the climate change goal. But it is still correct to have said it if her comment was restricted to climate change because of the potential for significant irreversible future consequences if serious climate impact correction is not achieved by 2030 (the date for all of the SDGs). Many people did not bother to ask her to clarify what she meant. She could have, and probably would have, done that. And some reporters, after obtaining a better understanding of what she meant, could have asked the people who criticised her 'sales-pitch' what they think of the clarification (some of them would dislike the achievement of the SGDs, but probably would try to not admit it).
It is important to understand that people like Trump do not like to be asked to explain themselves (that is why he limits his interviews and loves His One Way Rallies with his Loyal Fans). AOC and Mann are the opposite (in spite of claims that they are just appealing to 'their base' with their sales-pitches).
Not all sales-pitchers are bad. The intention is what matters most. And seeking clarification of a sales-pitch helps determine if it is intended to improve awareness and understanding to help develop a sustainable and improving future for humanity, or is harmfully misleading and hoping to be appealing.
Helpfully tugging on Heart-strings can be effective. And a jolt to get the heart pumping can also work. But, tragically, the likes of Trump prove that anger and fear based passion is more motivating. The likes of Greta and AOC appear to be on to that, but in a helpful rather than harmful way.

OPOF: "So AOC...did not exaggerate".
AOC said: "the world is going to end in 12 years if we don't address climate change".
Well, I guess I would have to agree that this is not an "exaggeration". But only if I'm allowed to call it a "lie". But let's just settle on "hyperbole" because that is what it was and I don't for a moment think she believed her statement was actually true.
And the effects have all been negative. Climate deniers are having no end of fun pointing out how ridiculous the statement was. And climate proponents are having a pretty hard time defending her statement as hyperbole (response by climate deniers: "yeah like all climate science!").
This was a fail for climate change. No question.

Doug @13: Here's the "About" statement posted on the website of MIT's Center for Global Change Science (CGCS). Note the final paragraph in particular:
The Center for Global Change Science (CGCS) at MIT was founded in January 1990 to address fundamental questions about the global environment with a multidisciplinary approach. In July 2006 the CGCS became an independent Center in the School of Science. The Center’s goal is to improve the ability to accurately predict changes in the global environment.
CGCS seeks to better understand the natural mechanisms in the ocean, atmosphere and land systems that together control the Earth’s climate, and to apply improved knowledge to problems of predicting global environmental change. The Center utilizes theory, observations, and numerical models to investigate environmental phenomena, the linkages among them, and their potential feedbacks in a changing climate.
The Center builds on existing programs of research and education in the Schools of Science and Engineering at MIT. The interdisciplinary organization fosters studies on topics as varied as, for example, oceanography, meteorology, hydrology, atmospheric chemistry, ecology, biogeochemical cycling, paleoclimatology, applied math, data assimilation, computer science, and satellite remote sensing.
CGCS sustains a program of discovery science with research on the natural processes in the global environment, concentrating on the circulations, cycles and interactions of water, air, energy, and nutrients in the Earth system.
Parallel CGCS activities incorporate the insight gained into climate prediction models, and climate policy analysis, with the aim of providing it in a useful way to decision-makers confronting the coupled challenges of future food, energy, water, climate and air pollution (among others). The CGCS also interacts with complementary MIT efforts in the Environmental Solutions Initiative, the Energy Initiative, and the Earth Resources Laboratory.
Given that cutting-edge research about carbon capture is occurring at MIT, you might want to nose around the CGS website to see if your question is being addressed.

OPOF @, I do agree to the extent the middle grounds people need a bit of a shock or jolt. The tipping point paper does that nicely, but at least it is science based and makes it clear boiling oceans are just a possibility.
It's also interesting that the extinction rebellion people have resonated with the public in what looks like a largely positive way despite the scary and extreme name. I'm undermining my own argument a bit here, but I like to be open minded and not stubborn.
But mistakes, hype and exaggeration does annoy me. It's possibly because I did a couple of years in quality assurance, in a management role, and it cultivates a nit picking sceptical attitude. I make no apologies for that.
I think past a certain point exaggeration and stupid claims will have the reverse effect of whats intended. Ie self defeating. And while Manns claims are defensible, just, AOC was simply mistaken even if well intentioned and it undermines her many good contributions. The GND is definitely a big shock sort of policy, but that at least can be logically defended.
If people cry "fire" too often people eventually stop listening. But the tipping points research is the right sort of shock doctrine, because its evolving and has a good foundation.
Yes the slow steady kumbya style of the moderates is frustrating, but politics is politics. These people don't respond well when shouted at. They like to see evidence based reassoned argument, and not too much hype and emotional button pushing (like Trump does to people and it only really works well with his base).

ed56@9, scepticalscience is just a name. Names need to be short and calling the website "busting climate myths.org" is long and corny and could be interpreted in different ways leading to the need to write "busting the climate myths of the climate sceptics.org which is even longer.
Yeah maybe the intent in the name sceptical science was to fishook in a few climate sceptics. No big deal. Clever move.
But I get your point that Sceptical science implies scepticism should be broadly applied. I think it would be useful to have the occasional article looking at some of the extremist warming claims and dissecting them. Eg climate change will cause human extinction, and the ridiculous claims on arctic-news.blogspot.com.
This website is probably not the ideal venue for looking regularly at mitigation and adaptation and the pros and cons, ie a sceptical analysis, because it can't do everything, but it could look at the occasional mitigation issue such as the very science heavy ones. In fact it did that a year ago by taking a look at the claims made by Alan Savory about regenerative cattle farming being able to sequester vast quantities soil carbon, and took a sceptical position. Heres the article.

I'm thinking more along the lines of what we do, something that can do better than the current Google results on a question such as "how does co2 capture via chemisorption compare iin cost to direct capture." If you try that query there's no obvious place to go.

One Planet Only Forever at 03:25 AM on 7 December 2019Video: Is CO2 actually dangerous?
nigelj @40,
It would be great if 'moderates' could become passionate defenders of the future of humanity. But without a 'shock' many of the fence-sitters and by-standers are likely to remain neutralish and resist learning that developed ways of living that are popular and profitable are actually very harmful and need to be stopped.
The article about tipping-points indicates that there is the potential for 'the boiling of the oceans' (runaway hot-house earth) due to interactions between tipping-points. And it identifies that if dramatic corrective action is not taken during the next 12 years (now to 2030), the world of the future several 1000s of years that humanity could have been able to quite easily enjoy sustainably living is very likely to be Gone Forever, no possible fix to bring it back.
Climate Adam's video about the 'harm' of CO2 is valid. And the article about tipping-points indicates that limiting the impacts to 1.5 C is 'scientifically the requirement'. More than 1.5 C warming impact is unacceptably risking harm to the future of humanity, potentially bringing about more rapid changes that are far more challenging to adapt to.
The excuse seekers like to hear that 2 C is OK (and even warmer would be OK you know - to be fair to current day people). They are likely to be turned off by any attempt to get them to understand that more than 1.5 C warming impact is unacceptable, because that understanding actually leads to admitting they need to sacrifice some of their developed ways of enjoying living, and stop trying to profit from fossil fuels.
So AOC and Mann did not exaggerate. They stated 'shocking' potential future consequences. Some people succeeded in getting Others to believe that the statements were reasons to be dismissive of the concerns being raised by climate science (just like the Climate-gate email scandal was abused).
I still maintain that anyone 'significantly doubtful and reluctant to learn' because of what they 'perceive' to be an exaggeration is 'just looking for excuses' and they will always be able to find excuses.
The problem is not the attention-getting claims made by AOC and Mann. The problem is people who are looking for excuses to be less interested in paying attention to the issue and learning about the issue.
Unfortunately, current day politicians respond to unreasonable popular passion (that is what a system that rewards based on popularity and profit will develop). I wish that would change. But until it does "Shocking people into paying attention" is likely a helpful action. Climate matters are definitely in the News more (even in the Fake News more), potentially because of those 'shocking comments' (and Angry Teenage Greta).
Anyone resisting learning about the corrections that are required 'because they do not like to be shocked' is likely not genuinely interested in being helpful even if they claim to be. Many people can claim to be very concerned about climate change, maybe even saying it is their highest concern, but would still vote for a party that definitely acts contrary to that concern because of Other Concerns (often based on made-up claims and unjustified beliefs targeting status quo tribal selfishness) that tempt them to like that party.
The slow and steady, 'Kumbaya style - Let's all just get along' approach of the moderates has been a damaging failure through the past 30 years. Sadly, the new generation being significantly angry and motivated to vote (along with the adults who care about the future) may be the solution. That can be expected to be viciously resisted. But the future of humanity is actually at stake.
CO2 is potentially very Harmful.

There's a lot of redundant babble in the popular climate communications world and there could certainly be benefit from more specialization. Perhaps there is such a site— I don't know of it myself.
But as to whether or not SkS is useful, site access statistics show a clear result: some half a million persons per month arrive here and land on specific articles debunking various climate change myths. It's a very purposeful and objective use of the site. These people are on personal fact-checking missions and we're here when they need us. There's no other such resource available.
Skeptical Science is specialized on providing factual corrections to climate misunderstandings. That's our stock-in-trade, our raison d'etre. We're a climate myth debunking encyclopedia.
Perusing the "Humans dealing with our global warming" section above suggests several other available specialty communications slots. A site focusing on popular conveyance of human cognition of hazards and risks would certainly be good. Much of our problem in dealing with climate lies in our poor mental faculties for that.

ed56 @9:
If you click on the About button on this website's Home Page, you will find the following statement:
Skeptical Science is a non-profit science education organisation, run by a global team of volunteers.
The goal of Skeptical Science is to explain what peer reviewed science has to say about global warming. When you peruse the many arguments of global warming skeptics, a pattern emerges. Skeptic arguments tend to focus on narrow pieces of the puzzle while neglecting the broader picture. For example, focus on Climategate emails neglects the full weight of scientific evidence for man-made global warming. Concentrating on a few growing glaciers ignores the world wide trend of accelerating glacier shrinkage. Claims of global cooling fail to realise the planet as a whole is still accumulating heat. This website presents the broader picture by explaining the peer reviewed scientific literature.
Often, the reason for disbelieving in man-made global warming seem to be political rather than scientific. Eg - "it's all a liberal plot to spread socialism and destroy capitalism". As one person put it, "the cheerleaders for doing something about global warming seem to be largely the cheerleaders for many causes of which I disapprove". However, what is causing global warming is a purely scientific question. Skeptical Science removes the politics from the debate by concentrating solely on the science.
This has been the mission of Skeptical Science since its inception and will continue to be its mission in the future.

Being a skeptic is not being given a license to lie. The science underlying AGW is almost 2 centuries old, and has been independently researched and validated as accurate by the fossil fuel companies themselves.
I understand that pretend-skeptics don't like actual science that runs counter to their preselected opinions, but then, that's not skepticism. It's flagrant denial: denial of facts, physics and history.
Time and history are not on the side of pretend-skeptics, for the time for denial is long over.
All that is left is to stand up and be counted, either as someone who understands science...or someone who doesn't.

Red Baron @36, my reference to all the eggs in one basket only suggested that a miraculous (like really dramatic) level of results from rotational grazing would mean not needing biofuels. I made no reference to not needing anything beyond that, like not needing renewable energy. I think I was clear. And theres no evidence of miracles being likely but there is evidence of something useful.
Since you at least appear to concede we need biofuels, this will place firm limits on land areas available for grazing, which was always my point.
I agree with the rest of your comments. I tend to think there are questions about the long term sustainability of the industrial and corporate farming model, and also intensive dairy farming, particularly using feed crops. Something looks like it has to change, and the benefits to the climate might almost be a side effect of this broader level of change, if that makes sense. When there are a lot of reasons to do something, we should mostly just do that thing. We might be looking at a longer term agricultural transformation that goes well beyond 2050.
I will leave it there, and I probably wont comment more on all this for now.

ed56 @4, I hear you, but read the mission statement for this website at the top of the home page "This website gets skeptical about global warming skepticism." Having read much of the so called global warming scepticism myself, there is much to be sceptical about their claims. This website can't be all things to all people, and it focuses on getting sceptical about what the climate sceptics / denialists like to claim.
However there is published science from time to time that takes a sceptical position on mainstream climate science positions, and you sometimes see this in the weekly list of research papers.
The greenhouse effect is established science, so there's no particular reason to be sceptical about it, in the same way theres no reason to be sceptical about the earth orbiting the sun. The things in genuine doubt include the exact effects of clouds and this gets discussed from time to time.
And "warmists" argue with each other quite frequently for example look at the comments posted on the article "Video:Is CO2 dangerous" in the list of recent articles. So theres plenty of scepticism if you have your eyes open.

Scientists the true skeptics - demanding evidence for everything. Pseudo-skeptics are only skeptical about positions that offend what they would like to beleive, swallowing garbage without a blink if it backs their preferrences
"Then again, when there is no refusal of AGW (any more), why does the world need a website like this?"
If that true, then sure, the site could shut down. However, visitor no.s suggest otherwise. If you think there is no refusal of AGW anymore, then just peruse back through the "comments" link at top for a few pages and see whether you still think so. There is a very strong science consensus but not so much among the voting public who clearly prefer to convenient lies.

The author and the project may be 100% right in their scientific positions, but why the 'Skeptical' in the title?
There is not skeptic attitude anywhere in this article or the whole website. You report that the mainstream finding is the mainstream finding, you repeat over and over that consensus has been reached and that there are no AGW denial positions.
So why not change the name to 'Truescience.com'?
Then again, when there is no refusal of AGW (any more), why does the world need a website like this? -

No nigelj no one ever said we should put all eggs in one basket. Not IPCC Not Holistic management and not me.
This apparently is a lack of communication.
Potential for a sink size and rate does not mean that will be the actual any more than a 8 oz glass of water holds exactly 8 oz of water. This is the potential should all agriculture world wide adopt holistic management.
Clearly the herculean task is in changing to regenerative practises. Very likely most the agricultural infrastructure will not change any time soon.
But it is important to understand the potential, so when we say change maybe 10% of agriculture, a very reasonable and fairly easy thing to do, then we have 10% of that total potential we can count on.
Too often people misuse the reports like the IPCC and others have put out and take numbers that have already been adjusted due to probable % of adoption, and adjust them once again! So rather than 10% we end up with people thinking 10% of 10%.
The potential is as large as total emissions and could put us in drawdown if all was changed, but it won't be all changed any more than all fossil fuel emissions eliminated.
Neither one is going to happen.
But if we meet somewhere in the middle with dramatically reduced fossil fuel emissions, the soil sink is plenty large enough and the rate of sequestration fast enough that we could reach a draw down scenaio.

Red Baron,
Replying to your comment at 31:
As I said before, your links do not support your wild claims. For example, your link to Project Drawdown. To start off the page you linked does not talk about grazing at all. It is your responsibility to provide correct links.
After searching the site I found this page on managed grazing. They claim that it might be possible to remove 16.34 gigatons of CO2 by the year 2050 using managed grazing. At comment 29, you claim that managed grazing could remove 35 gigatons of CO2 per year every year until 2050. Thus you claim approximately 65 times as much carbon dioxide fixed as your reference.
The teraton initiative you linked appears to be a new project by a journalist and author. He claims that the advantages of regenerative agriculture have not been systematically measured in the past and is trying to measure how much carbon is actually fixed. All the pages I saw were about general agriculture. I could not find a page on grazing. Their calculations were all back of the napkin with no supporting science.
The teraton initiative and you both make the mistake of claiming that if you remove the extra carbon dioxide from the atmosphere the problem will be solved. Reality is worse than that. If you start to remove carbon from the atmosphere, carbon dioxide absorbed by the ocean will outgas making the problem bigger. Good luck.
You made the wild claim at the start of this discussion (lost because it was posted on another thread off topic) that in the past year or two scientists have come around to your ideas in mass. You have provided no link to even a review article, much less a summary report, to support this wild claim, not even one that does not support your claim. The references in the OP are so recent it is unimaginable that scientists would have changed their minds en masse.
We all wish that argiculture would be a magic bullet to solve AGW. Agriculture might provide a wedge or two, but many other actions will be required to turn back the problem of CO2 pollution. It does not help to motivate people to act if you falsely claim there is an easy way to solve the problem.

RedBaron @39
There's nothing inconsistent between my comments and your IPCC cut and paste, which doesn't define what the IPCC means by integrated. I mean its all fairly general but looks right in principle.
You are giving your understanding of what integrated means. But yes ok integrated farming with less monoculture and more mixed types of farming and regenerative farming might increase meat production potential. I would need to see some published research on that. I do think regenerative farming is the way to go in general principle anyway.
(I work in a design field, but I did a couple of years in quality assurance, and its made me very critical, sceptical and nit picky as I'm sure you would appreciate. But I make no apologies for that.)
I've gone back and read my comment here : "So given rotational grazing uses more land than intensive corn fed dairy farming, its rather looks like lower meat consumption to me rather than higher meat consumption." There is no fault with this all other things being equal. The integrated farming methods you propose would offset this to at least some degree, but it doesn't make my original statement wrong in any way.
I'm all for sustainably produced diets with some meat. The minimum recommendation is 60 grams of protein per adult per day and meat is a good source of protein. But many people in western countries eat far more than this, and perhaps some people in the third world dont get 60 grams but I'm guessing this would not be widespread. 60 grams is not very much, especially as a typical piece of fillet or sirloin steak is at least 100 grams.
Vegetarianism is at the other extreme and doesn't make sense to me environmentally because we have vast tracts of grasslands that only really do suit cattle, so they would be challenging to turn into crop lands.
The thing is we do need biofuels. They are about the only way to realistically get to carbon neutral air travel and shipping. Now I'm as nervous as you about vast areas of land being vacuumed up for biofuel crops, but at least some land looks like its needed.
If rotational grazing could be guaranteed to produce near miraculous levels of drawdown of atmospheric carbon, this might be a case to put "all our eggs in that basket" and say we dont even need biofuels and growing more forests, or things like BECCS, but the picture I get from all the weight of the research and commentary and articles on this website is that rotational grazing just has moderate benefits. I think higher than the harsher critics think, but less than you think.

OPOF @40, I agree that hard core denialists wont be more in denial by mistaken claims about warming, but we are not talking about those people. We are talking about middle ground people and fence sitters who in my experience very sensitive to hype. When they sense exaggeration or big mistakes, they loose confidence.
The research on tipping points is not an exaggerated or mistaken claim, as far as we know. I dont think you can compare that to Hansens claim about boiling oceans or AOC who said the world will end in 12 years. Both should have known these statements were wrong, and shouldn't have made them. Alternatively they could have been more nucanced and labelled them exreme possibilities, or something like that. This would get around your concern that there has to be a place for speculation.
Dont take it as a general criticism of AOC.

RedBaron at 04:47 AM on 6 December 2019Holistic Management can reverse Climate Change
Since I have been accused of sloganeering and had my IPCC comment snipped...
Here is the IPCC report: IPCC Report: Climate Change and Land
The report states with high confidence that balanced diets featuring plant-based and sustainably produced animal-sourced food present major opportunities for adaptation and mitigation while generating significant co-benefits in terms of human health.
For context the entire paragraph
B6.2. Diversification in the food system (e.g., implementation of integrated production
systems, broad-based genetic resources, and diets) can reduce risks from climate change (medium
confidence). Balanced diets, featuring plant-based foods, such as those based on coarse grains,
legumes, fruits and vegetables, nuts and seeds, and animal-sourced food produced in resilient,
sustainable and low-GHG emission systems, present major opportunities for adaptation and
mitigation while generating significant co-benefits in terms of human health (high confidence). By
2050, dietary changes could free several Mkm2
(medium confidence) of land and provide a
technical mitigation potential of 0.7 to 8.0 GtCO2e yr-1, relative to business as usual projections
(high confidence). Transitions towards low-GHG emission diets may be influenced by local
production practices, technical and financial barriers and associated livelihoods and cultural habits
(high confidence).This is integrated production models, not vegan diets and not as you said "reduced meat". It specifically says integrated which to a farmer has a very specific meaning. That means rather than monocropping and using those commodity feedgrains to supply the CAFO (concentrated animal feeding operation more commonly called factory farm) system , instead the animals are returned to the farm and the land and there they can fulfill their ecosystem functions for the farmer, usually in some sort of rotational system. Also please note these changes in production and consumption "could free several Mkm2
(medium confidence) of land" This is because integrated farming systems yield much MORE food per acre, compared to the factory farming system. I will repeat, they yield more in terms of yields per acre, not less. Factory farms are only more productive in terms of yields per man hour. They do not yield more food per acre.Every one of those points Savory has repeatedly said over and over. And yet people with no knowledge of agriculture read the exact same paragraph and conclude meat consumption must drop.
The key here is sustainably produced balanced diets. Yes in some cases that might mean less meat, in many cases around the world it actually means we need more meat to make properly balanced sustainable diets. Overall globally there are many more people who would benefit from more meat in their diet, not less. And if we change to integrated sustainably produced plant and animal foods, it will actually reduce the amount of land needed for agriculture, allowing large areas to be restored to the biomes present before human impact.
Exactly yet again what Savory both advocates and has proven in his award winning proof of concept.
“The number one public enemy is the cow. But the number one tool that can save mankind is the cow. We need every cow we can get back out on the range. It is almost criminal to have them in feedlots which are inhumane, antisocial, and environmentally and economically unsound.” Allan Savory
PS There is an elephant in the room though. Right now we have all surplus commodity grains producing biofuels. Reducing land in food production by integration of sustainably produced plant and animal foods will not actually help at all if we continue to send all commodity surpluses for biofuel and other industrial uses. So even if you were right that reduce meat consumption was needed, it would not necessarily have the impact you envision. Land would still be deforested to fill this nearly unlimited demand. Even desertified land restored by holistic management would likely soon after be put to the plow to fill the demand for biofuels and desertify all over again.
In my opinion this sort of industrial use must be either eliminated or highly discouraged or else none of the other issues will improve at all. It will become so much "shifting deck chairs on a sinking titanic". That last part is my opinion based on the current market dynamic.

nigelj @39,
It is highly likely that anyone showing little interest in pursuing more awareness and improved understanding of climate science 'because of comments made regarding the potential worst consequences of a lack of corrective action' actually has no interest in expanding their awareness and improving their understanding regarding this issue.
By the standard you set, the article I linked to at the end of my comment would be banned from publication. Even presenting the range of possible future consequences the way the IPCC does would not be allowed.
If the qualification is added that the near term range of climate change should be able to be presented, then why not the 'possible' longer term realities of a lack of correction, why stop at presenting the consequences in 2100? What about the consequences in 3000?
The approach you suggest, without opening it up to wider awareness, is like saying scientists should only report absolute certainty. And any science-minded individual understands the repugnant absurdity of that.
That demand for certainty is the main basis for resistance to correction of harmful developed activities. The claim is made that those activities (the people wanting to benefit from them), cannot be stopped or even be penalized unless there is a very high degree of certainty. Any question at all means nothing should be done to stop or discourage the activity. That is playing the game the way the likes of Singer want it played. And that is a dead-end game for humanity.

Perhaps this websites main page could have a permanent link to Climate Adams Videos and Potholers videos and similar videos titled "Interesting Videos", or "Interesting Information". Their work goes to the heart of debunking myths. A brief description could indicate the basic differences in their approaches.
OPOF @38, maybe yes, maybe no. I think that when the average person hears about warmists exaggerated and incorrect and easily debunked claims, its never a good thing. We could debate forever whether this is so and whether it significantly alters their perception of things, but there's an easy answer: Do the homework and don't make exaggerated and mistaken claims. Don't give denialists even the slightest ammunition.

Red Baron @29, I haven't kept a record of my calculation, but I was going by a smaller land area that I got off some website ( it looks like it was wrong), and I factored in an allowance for the fact that warming will cause some loss of soil carbon eventually as has been established in research. So my estimate was probably too low, however I doubt we would achieve your optimistic numbers either.
And like I said, there are huge competing requirements for land, and they are valid requirements. Realistically you are going to probably have to make the best of current grazing areas, and even that will be optimistic. So given rotational grazing uses more land than intensive corn fed dairy farming, its rather looks like lower meat consumption to me rather than higher meat consumption.
Savorys ideas about reclaiming desert look rather optimistic. This would not just happen in a market economy, there's not enough profit in it, and it would need massive tax payer subsidies. Again there are many competing requirements for tax payer subsidies.
However I do think theres a case for subsidising proper rotational grazing methods etc as best we can. Carbon taxes and cap and trade are too indirect to usefully promote your ideas.
So yeah the rotational grazing thing still looks very useful to me and would sequester significant carbon, but you have to be realistic about what can be achieved in the real world. Don't over hype it. Sometimes selling an idea effectively requires being just a little bit understated.

Different styles of communication will reach different people.
Any action that has a chance of changing the mind of an older person is helpful.
However, what is most important for the future of humanity is inoculating the younger generation against the temptations towards selfish interest that can convert a More Helpful Thoughtful Person into a More Defensive Correction Resistant Harmful Person.
Cranky Uncle and Climate Adam (and Greta) are likely better at that inoculation effort on the younger generation than Potholer54 (John Oliver seems to be better at providing a detailed inoculating presentation that appeals to younger people - cuz he effectively uses Hyperbole and cusses).
As for the 'tragedy of hyperbole' by the likes of Mann and AOC creating 'easy Wins' for the group wanting to resist corrections of harmful unsustainable developed human activity. Anyone easily impressed by the criticisms that are made-up based on those hyperbolic statements is unlikely to be moved to change their mind by a detailed presentation of the reasons to change their mind (nothing to do with the hyperbolic statement). Their lack of effort to investigate the merit of the criticism of the likes of AOC and Mann is likely due to a Powerful Developed Bias that would not be easily chipped through by attempts to appeal to their ability to be reasonable and helpful.
And this recent Comment published Nov 27 in Nature "Climate tipping points — too risky to bet against" is more 'valid hyperbole' with a detailed presentation of current developed understanding that appears to indicate that Mann and AOC were only being 'a little bit hyperbolic'. The potential for passing significant climate change tipping-points by a failure to 'get control of what is going on and effectively correct things by 2030' appears to deserve to be a serious concern for the 'Future of the world that humanity hopes to continue to live in' even if some people will 'get popular support for claims that it is absurd hyperbole'.

@michael Sweet,
I have back up all claims as well as debunked the false claims in the OP multiple times, if that's what you mean, sure.
And yes I have done this for years, and slowly the consensus of scientific opinion has been moving this direction too.
There are many many comming around, project drawdown being a great example: Project drawdown
Terraton initiative being another.
Even the IPCC admits it, but is under the mistaken notion that changing agriculture would lower yields, so makes the mistaken assumption relatively small acreage could be changed. In fact yields for increase substantially. So that is why although they agree it could be significant, they lowball it.
Now it is to the point that the OP position posted here is decidedly minority, Actually in my opinion it is actually a merchants of doubt talking point that somehow got past Skeptical Science..
I am not critical of Skeptical Science though, because the merchants of doubt used a shotgun approach and fired literally hundreds of obfuscation attempts and the fact you managed to debunk them all but one is pretty impressive actually.
I am just trying to help you tackle the one you missed.

You have been making the same claims here for years. I read your references and they do not support your wild claims. The OP here reviews the literature on this topic and clearly states that your claims are not supported. A review of the comments sees you repeating the same unsupported claims.
Better farming methods will help and fix a little carbon. Your claims that all released carbon can be sequestered are simply false. There is no magic bullet in graising.
New readers should read the OP for a more balanced evaluation of holistic grazing.

RedBaron at 23:42 PM on 4 December 2019Holistic Management can reverse Climate Change
There is approximately 3.5 billion ha of grazing land already. approximately 80% of it is currently over grazed or under grazed.
10 tonnes CO2e/ha/yr x 3.5 billion = 35 billion tonnes CO2e/yr
Global emissions are in that range as in 2018, global fossil CO2 emissions totaled 36.6 billion tons.
That is not counting restoring desertified land as Savory advises, nor does it count restoring farnland currently being used unwisely for commodity crops to fill a highly wasteful and unsustainable industrialised commodity system. That's about 320 million hecares worldwide that less than 1/2 of which actually feeds human beings. So another 1.6 billion tonnes CO2e/yr.
But wait there is more. Most the haber process fertilizers and fossil fuel usage for supplying these foolish production models all add up to approximately 15-20 % of emissions worldwide. Just fixing them alone potentially reduces emissions ~7.2 billion tonnes CO2/yr.
35+1.6+7.2 = roughly a potential of 43.8 billion tonnes CO2 offset against a total emissions of 36.6 billion tonnes emissions and already about 1/2 of that is already offset by natural systems!
We have the potential for drawdown. Maybe just by using holistic management to replace the commodity corn system and regenerate desertified lands.
So I am not sure at all how you obtained a potential of only 10% since you have not shown your figures.
Of course that's theorectical potential. Much like the potential for renewable energy, the actual numbers are fairly certain to fall short of the potential. Not everyone will change agriculture in a single year. It takes decades for training and infrastructure etc... and that's only after the actual commitment to make the change in the first place.
So of course reductions in fossil fuel use will need to be made to meet it 1/2 way in the middle somewhere. But certainly actual drawdown is possible. No other drawdown potential exists using any other technology currently available.

RedBaron @27
You have made a sweeping statement that I got everything wrong. You have learned literally nothing about my comments about diplomacy. Most people are going to react to that sort of comment by dismissing both you are your ideas. Fortunately for you I have a thick skin and control my temper.
It's also an immensely silly statement, because some things I said are what you have said, or close enough.
You have not answered my question in paragraph 5. Again, you show no diplomacy, and no respect.
You have mentioned one specific thing that you disagree with: that I think we should eat less meat. You think we should eat more meat, but this doesn't make sense to me, because it means we need even more land for cattle. Do you not realise there is competing demand for land for biofuels, and beccs and foresty, and crops to feed a population heading to 12 billion people at least, and urban development?
Meat is a very inefficient use of resources requiring enormous inputs of land, biomass and water for a small quantity ofprotein outputs. Obviously you must know this.
Yes I understand the "corn" issue in America, but that is only one component of land demand as I've outlined.
It's really unlikely we can or should expand areas of land for grazing. Given rotational grazing is land intensive, if anything per capita meat consumption probably thus needs to fall, although not drastically.
Now you would presumably argue that actually hugely expanding grasslands for cattle farming is a great thing, because it draws down atmospheric carbon, and so this should all take precedence over everything else. This would be a big claim so needs massive levels of proof. I have had a look at the numbers, and even taking your best numbers of 5-20 tonnes CO2e/ha/yr, and using 10 tonnes, this gives something like a reduction in about 10% of our total current emissions per year It's still a good number - but as pointed out on this website about a year ago it falls well short of the sort of claims made by people like Savory no matter how you try to spin it. And this assumes literally all farms work regeneratively, ( a massive scaling up operation with huge challenges) and this soil carbon diminishes over time as soils heat up and upper layers become a net carbon source.
The whole rotational grazing proposal has merit, but would therefore take a very long time to make a dent in atmospheric concentrations of carbon, so its hard for me to see a case for scaling up your proposal above current land area.
I can however see a very good case for making better use of what land area we "currently" use for livestock farming, and using Savorys rotational grazing system.
If you think my maths is wrong, by all means check it and tabulate your own calculations in an ordered fashion but my rough boe calcs and conclusions are not much different from scientists who actually specialise in this area.
I think you are in danger of coming across as an obsessive scientific crank with their pet project somewhat like Killian over at realclimate.org! Now perhaps I'm not being too diplomatic myslelf :) Imjust giving you a bit of advice.
You have posted a lot of details and links on soil science. I'm not disputing that stuff in the main and never have. So if you want to post it don't do it for my benefit, but perhaps you are doing it for other people reading.
To summarise, I do accept there is a valuable looking pathway where properly grazed pastures encourage the glomalin pathway and leads to deeper carbon rich soils ultimately, and as such we should farm that way, but the process looks slow to me, and theres not exactly a scientific consensus on the effectiveness of the issue, and there are many competing uses for land. As such its hard for me to think we should actually expand grazing lands, but rotationally grazing what we have seems logical. I think you are right in general terms, but you may need to be more realistic.

RedBaron at 13:59 PM on 4 December 2019Holistic Management can reverse Climate Change
@Nigelj,
Glad we are talking again, but you are still completely wrong. I am not sure how overly simplified I need to make this....
If something is beneficial, we need more of it. If something is harmful, we need less of it. Is this simplified enough for you? I am proposing eliminating many harmful practises in agriculture, and increasing many beneficial practises.
It makes no sense at all to go through all the trouble of changing agriculture to regenerative practices, then reduce our usage of those beneficial systems. You got it backwards.
You said, "The solution is to reduce our meat consumption and plant trees and farm in ways that enhance the ability of soils to absorb carbon. Proper rotational grazing can enhance the ability of grasslands to absorb carbon, so there is no need to completely stop eating meat."
That's backwards. It makes sense only if we DONT change agriculture.
Actually we need to increase meat production significantly. Global hunger and cronic malnutrition affects 815 million people (Food and Agriculture Organization [FAO] et al., 2017) As developing nations pull themselves out of poverty, they can afford more meat in their diet and balance their nutritional requirements much better.
The thing that needs to be dramatically reduced is commodity crops used to make biofuels and supply feedlots and other factory farms, make high processed foods like high fructose corn syrup etc... Cornfields need switched to forests and grasslands depending on the biome that was destroyed to make the cornfield. We can then actually raise more animals than now, cheaper, healthier, and beneficial to the newly restored environments we are now raising them in instead of CAFOs.
This would increase the meat supply significantly and drive the price down too. Especially if the ranchers and farmers got paid for the increases of soil carbon.
Its a win win all around for everyone.
