NorrisM;
You referred to a book by Dessler upthread. Would that be this one?
https://www.amazon.ca/Introduction-Modern-Climate-Change-Dessler/dp/1107480671
Note that Dessler is a climate scientist, not a journalist.
Out of curiosity, what was the other book?

aleks@33, from the paper you cited, there is the following cautionary note.
“What we are seeing is that the Earth continues to do the heavy lifting by taking up huge amounts of carbon dioxide, even while humans have done very little to reduce carbon emissions,” said Ballantyne. “How long this will continue, we don’t know.”
The fact that the earth is absorbing large quantities of our emissions is great, but it has its limits. The fact that the offset of current CO2 compared to preindustrial is 3 times higher now than in the late 1960's but the authors say the uptake has only doubled may already be a sign that the uptake is slowing down. This is the nature of systems as they become saturated.
We are digging up carbon and dumping it into the above-ground systems at a rate they are not accustomed to. The result will not be good. We need to start leaving the carbon below ground where it is, instead of trying to convince ourselves that either nature or our technology will find ways to put it back underground. Why not just leave it where it is?

aleks@33 Yes, H2O is a primary combustion product together with CO2. For "clean fuels" such as CH4, twice as much H2O is emitted as CO2. But the excess H2O just falls out of the system as precipitation. So the only increase of the steady-state H2O concentration is through the Clausius-Clapeyron equation, and is not due to direct emission of H2O. That is, the only way that the steady-state concentration of H2O can increase is if there is an increase of temperature first. Direct emissions of H2O do nothing to inrease to increase steady-state concentrations of H2O.
Regarding uptake of CO2 doubling, I am not an expert in this area, but this number does not surprise me, and it does not make me feel better. Consider that for about 10,000 years during the Holocene that background CO2 concentrations were about 280 ppm. The fact that the concentration was stable means that sources and sinks were in equilibrium. Then comes the industrial revolution and we start to ramp up CO2. By the late 1960's the CO2 concetration had increased to about 325 ppm. This is an increase of 45 ppm above the steady-state value during the Holocene. The result is that the earth starts to absorb more CO2 to draw down the concentration and to try to restore balance. Now we are at about 405 ppm, or about 125 ppm above preindustrial, and about 3 times higher than the 45 ppm inbalance representative of the late 1960's. So it is not surprising that the rate of sequestration has doubled in the last 50 years, because the increase above preindustrial has tripled. Far from making us feel better, the fact that we are dumping such huge levels of carbon into the natural system represents a deviation from the steady-state balance we had for 10,000 years, and such a dramatic departure should make us worry about what effect this will have. Such as ocean acidification. We know some of the good benefits, but we may yet discover that there are other not-so-good effects lurking in the dark.

I'm puzzled by the Chinese air pollution from factories. The equipment to remove particulates and sulphur from the smoke stacks is off-the-shelf technology that America deployed decades ago to clean up her emissions. Why don't they just buy a few units, reverse engineer them and deploy them to all polluting factories. They even make money from the recovered sulphur. As for cars, they lead the world in electric cars and in installation of wind turbines and solar panels so vehicle pollution should sort itself out over time.

Thanks, I will definitely take a look at it. This whole climate change issue started from me reading two books on the subject, one for and against after my two sisters got into an argument. The "for" book was that of Dessler (if I have not said that above).

I am very impressed with your summary of that portion of the Harris podcast with Cass Sunstein. I should have qualified my comment to Eclectic that not the whole podcast is on freedom of speech. But it is very interesting on the other things discussed so it would not have been a waste of time.
We all agree that freedom of speech is very important in our society. Sunstein's point is that we have to tolerate wackos like Jones denying the Sandy Hook massacre to protect our freedoms because to do otherwise puts us on the slippery slope of quelling any dissent with the "popular view" which would be very dangerous. I think his summary of where the US Supreme Court has drawn the line is a good one and one with which I generally agree.
As to Miersch, I have since noted that at the time of my post I did not realize that he had strong views on climate change. Of course I am familiar with GWPF because it and Judith Curry's blog are the other two that I look at only occasionally. I have now searched on Wikipedia for the German Wildlife Foundation and it is not listed as a conservation society in Germany. I am somewhat disappointed in GWPF for not making it clear who Miersch is and is not. If the German Wildlife Society was in fact a true conservation society, leaving Miersch in the position as Director of Communications would say something as to their views but that does not seem to be the case.

Notwithstanding my comment in one of your replies on the models, I really do not want to engage this any further. I did gain a further understanding of the complexities of these models by reading the Chapter 9 of the IPCC 2013 assessment but I would prefer to deal with solutions. This moves more into an area where it is less technical and more political and economic which is easier for me to digest.
My sense is that we will be watching the fireworks on the ability of the models to assist in predicting future temperature increases if the EPA does proceed with the Red Team Blue Team. The July news item I cited suggests they are proceeding.

Final comment for the moment:
I commend you in that you have shown a willingness to obtain and read a variety of sources of information on the subjects that have been raised in discussion here.
I think that you give credibility to some sources that I consider to be highly unreliable.
If you have not been pointed to it before, I suggest that you take the time to read Spencer Weart's The Discovery of Global Warming. It is written by an historian - someone with expertise in the history of science.

NorrisM:
The phrase "Business As Usual" has different meaning to different people. When the IPCC assigned that term to one of their scenarios back in the 1990s, they assumed (IIRC) continued growth as seen in the past. It was a label assigned to a particular CO2 concentration growth under certain assumptions. It was not an indicator of a particular sociological or economic system.
Your examples of China reflect that things have changed since the IPCC first started using that term. None of the IPCC RCP scenarios exactly fit what has happened - but they were not predictions, they were projections to cover a reasonable range of possibiliities to see what difference it woudl make. Look back at my description earlier regarding "sensitivity analysis".
With respect to nuclear power, my personal position is that safety of long-term disposal of nuclear waste has not been solved, and that total captial and operating costs have continually been much, much larger than originally claimed. Nuclear has historically enjoyed much government support, and it seems unlikely that it can stand on its own without it. I am not against it as a solution to reducing fossil fuels, but I am not in favour of it if it costs more than other alternatives. {But we try to avoid discussions of nuclear energy here, because it will rapidly wander into non-climate-related arguments between fiercely devoted proponents of the extreme positions.)
As for my feeling about what you call a "head in the sand approach" - it is not that you are part of that group, but that you appear to readily accept information from those sources with less skepticism than you seem to apply to well-founded science. This is called "confirmation bias", and it is something that every person has in varying degrees (and varying topics for one individual). With a legal background, surely you can appreciate the question of the credibility of the witness"?

NorrisM: "I have never said that the best estimate of the additional costs is $0."
Yes, I agree that you never said that explicitly, and it was not my intention to imply that you had said it explicitly, but rather that your position to not include it is equivalent to placing a value of $0 on it. Thus, it is implicit in your position. Ignoring those extra costs in the risk management plan is the same as including them with a value of $0.
To further clarfiy my positon: going to the lowest common denominator (US federal position) is not acceptable to me. The evidence in this blog post is that individual US states and political postions are moving away from this scorched earth federal position. This is to be encouraged. The world's politicians (mostly) have indicated acceptance to the Paris Agreement. It is non-binding, but hopefully countries will live up to their promises, and will commit to the further actions needed down the line.

Evan@28,29, thanks for detailed reply. About natural removal rates for CO2. Please, pay attention to the research by A.Ballantyne a.o. (University of Colorado)
https://www.colorado.edu/today/2012/08/01/earth-still-absorbing-co2-even-emissions-rise-says-new-cu-led-study
The authors state that "natural carbon sinks that sequester the greenhouse gas doubled their uptake in the past 50 years".
Reference to the Clapeyron-Clausius equation shows that you consider water concentration change in the atmosphere only in relation to temperature. However, water emitted together with carbon dioxide at combustin of fuel in huge quantities. So, at burning of methane the yield of H2O is 2mole/mole CO2, for oil it will be slightly more than 1mole H2O/1mole CO2. Even coal contains about 6% H by mass. This is an additional evidence in favor of the significance of water vapor for the processes of heat exchange in the atmosphere.

MA Rodger at 21:32 PM on 22 October 2017Climate and energy are becoming focal points in state political races
NorrisM @152,
Perhaps I should explain why I brand you a troll. In rough terms, it is evident that you come to SkS with a contrary view but fail at every turn when asked to justify that view. You appear more interested in piling on the startling contrary views than in attempting to reconcile the views you express with the views others expressed here, those which are in the main science-based.
Strangely, I don't appear to have branded you a troll before, strange as I don't usually hold back for so long. But let us consider the detail of your use of Miersch down this thread.
@122 you introduced Michael Miersch into this thread as an aside, suggesting his message comprises news from Germany of "a major backlash" against renewable energy. By the sounds of it, he is an enemy of on-shore wind power and is being invited to speak in the seat of UK government (the Palace of Westminster) by a UK educational charity, the GWPF. Of course, the GWPF is no normal charity but a cynical bunch of climate change deniers. (The last time I heard of a GWPF talk at Westminster it was veteran climate denier Richard Lindzen.) I can't believe you would not have known about the GWPF given you tell us @112 that your understanding of Miersch is based on GWPF information. If you did not, its dodgy nature was set out @114. ( Interestingly, your acknowledgement of this situation @127 is riven with the sort of gramatical nonsense you would expect from an non-English speaker, suggesting you found writing it very difficult. Perhaps the message you wrote there was foreign to you!)
It is true that you were goaded into continuing further with this, but you did so by citing in the most general terms an 80 minute pod-cast to support the case of Miersch having the right of freedom of speech to say what he does (even though we still don't know what it is he does say). I listened to what I assume is the passage of that pod-cast which you were citing. (It's at about 1hr to 1hr 6 here) What Cass Sunstein is saying is that you cannot slander or libel a person (which the German government were accused of by Miersch, but which the courts said otherwise. The courts say there is no libel as Miersch is a Klimawandelskeptiker). Cass Sunstein also says that a person has the right to describe the Sandy Hook massacre as being a real or imaginary event that was orchestrated by the US government to enable tighter gun laws. As long as you are sincere and not lying, you are allowed to say such outrageous things. This can be said as this is not slander/libel - no individual is being defamed. And apparently some seriously sick people do brand Sandy Hook a hoax/conspiracy. As it is difficult to establish legally that they are sincere in their belief (an so not lying) they are imune to legal challenges. Sunstein was also asked about malicious 'doxing' replying that newspapers do have the right to publish the names and addresses of rape victims even if the intention was to unleash violence against them. Sunstein says this is poor law, saying on this of Madison (a US founding father, apparently) "(it is) not clear if Madison would roll over in his grave if we said you can't disclose where someone lives if the purpose and effect of that is to increase the risk of voilence."
So that is pretty startling stuff you cite to defend Miersch's right to say... well... frankly, I get the distinct impression you do not know what Miersch says on "wind and solar versus nuclear" and so who can say if he is "someone who shared my views." So this continues to be a troll-like discourse here, or have you a source of Miersch-ism you have, golly, forgotten to share with us.Moderator Response:[DB] Everyone: Let's please return to the topic of this thread.

Thank you, MA Rodger @150 , for the further details on the sad case of mendacious journalist Miersch.
Who says the Germans have no sense of humor?! . . . I love the Galileo-like title reference: "Und Sie Erwaermt Sich Doch". How appropriate!
This thread is certainly quite a broad umbrella of topics.
Alas, NorrisM @ 149 , even this broad thread is not broad enough for us to engage in a discussion of your tendency to moral nihilism. The admirable and witty Voltaire nevertheless was acutely aware of the difference between good and evil (and the gradations inbetween) -— and I rather doubt he would approve of your hijacking & extremist usage of his aphorism on "rights of speech".
As for who judges -— who better than a German court, it seems! ;-)
To a large extent, the Germans have learnt their lesson (after some "difficulties" in the 1930's and 1940's). And they have realized that a supine & laissez-faire approach to dealing with harmful lies & propaganda, is not a wise policy for society.
That the matter of "judgment" in these affairs is not easy, is no excuse to abandon the attempt entirely. Surely a lawyer should appreciate that the legal system exists to deal with the difficult cases as well as the easy cases. Fiat iustitia ...
~And no, there I wasn't spruiking for a new Red/Blue assessment. ;-)
The basic climate facts have have already been determined 20+ years ago : by the competent authorities. Nowadays it is merely required to summon up the moral fortitude to take the necessary remediations of the AGW situation.
More bluntly : it is high time we got off our butts.
(Which brings us back on topic for this semi-political thread ! )

Defn of Troll: "A person who posts inflammatory or inappropriate messages or comments online for the purpose of upsetting other users and provoking a response."
Very disappointed in your comment. If I do not agree with your view you get upset. I guess you would prefer to hear from others who agree with you. Much more comfortable staying in your echo chamber. So much for freedom of speech.
Moderator: If you snip some of this comment then I trust you will snip the term "troll" from the above comment. All I did was quote a speaker who was appearing in England who I read from another source was the Director of the German Wildlife Foundation. Given my personal views on wind and solar versus nuclear, it was nice to hear of someone who shared my views. Is it so bad to think that wind turbines are a blotch on our landscape? Subsequent to that I acknowledged that it was pointed out that he had a history of questioning climate change and was only Director of Communications for the German Wildlife Foundation. At the time I posted this I did not know his general views on climate change. This I assume has brought on the label of being a "troll".

Bob Loblaw @ 143
I have been very impressed by your arguments generally (interesting to see two Canadians go at it). But this comment really distorts what I have said and sounds like some others which look for some "underlying preconceived notions".
A few examples:
"Just because you want to label uncertainties in these costs as "vague", "theoretical", etc. does not mean that the best estimate of these additional costs is $0."
I have never said that the best estimate of the additional costs is $0. What I have said is that you will not get the US, Europe or China onside to recognize this because of the costs to their particular society in imposing some carbon tax beyond pollution costs. Of course, the future costs are much more than the pure "pollution costs". But unless you have a very easy alternative (as to costs and viability), then you have to weigh the benefits of FF to the future costs. I have already indicated what I think should be a two-pronged approach.
"That you keep repeating shop-worn denier talking points about uncertainty, models, etc. suggests that at some deep level you are still believing or hoping that the science is all wrong and no significant change is needed."
Wrong. It has nothing to do with hoping the science is all wrong. I also do not thing the science is all wrong. But my concern with the models, especially after having read a very honest Chapter 9 of the IPCC 2013 Assessment during my recent holiday, is that I do not think that we have the ability to model, by computers, the complexities of the climate to a level that we can fully trust them. I am not saying that the models are useless, but when I read in the IPCC assessment that the models have been "tuned" to match reality in "hindcasts" (in ways not disclosed to the IPCC) then it raises serious questions as to the ability of models to predict the future 50 years from now and suggest that sea levels really will increase at rates much higher than present levels. I understand that any model would have to be adjusted in hindsight to input things like actual volcanic activity and actual El Ninos and other actual ocean oscillations but my sense is that with these "adjustments" we are not much better off than taking a ruler and projecting sea level and temperature rises based upon the last 25-50 years.
That is why I have found myself reverting to what is actually happening both as to average temperature increases and average sea level rises over X period of years. I think it is eminently reasonable to assume, in the absence of evidence to the contrary, that things will continue at the same rates as we have seen. We had a "hiatus" for a period of 12-15 years in average temperature rise but I am more than prepared to accept that this was a "blip" and that temperatures will continue to rise because the CO2 emissions continue.
At 71 years of age, I am not concerned about myself or my economic position. I am concerned about the world but I am, more than anything, a realist. I have two adult children who will have to live in this world (I actually worry that there are other things that are more dangerous to their future welfare than climate change). So when I advocate things, I take into account political realities together with a general skepticism that we as humans are apocalyptic. Just remember that climate scientists in the 1970's, or at least a fair number, were suggesting we were on our way to another mini ice age. I just do not think that we are about to go over Niagara Falls. We have some time to see if this really is a problem. For at least 25 years, we have been told we were going "over the cliff" (or over the waterfall) and it has not happened.
I am happy to deal with linear increases. If we find that "linear' is in fact wrong, then we deal with it. That is why I have been trying to sort out what the actual sea level rise has been for the last 25 years.
The other thing I have not mentioned is my question as to whether the CO2 emissions will be the same over the next 30 years with BAU as it has been for the last 30 years. China has taken massive steps using cheap coal to fuel its industrialization. Hopefully this will not go on for the next 30 years. Surely they will not again "double" their existing steel production. Clearly China will be using wind and solar (in conjunction with their existing coal plants) to mitigate their pollution costs. As I type this, it has occurred to me that China is not focussing on nuclear power. I have never heard this from any of the commentators but that is probably one of the best arguments that nuclear power does not make economic sense. If a planned economy like China has not moved to nuclear power (and the Chinese are no dummies) then there are reasons that argue for wind and solar in favour of nuclear (I still find this disappointing for our world - I saw some of the wind farms in Spain). For some they are pretty, but to me it is a sad commentary on what humans are doing to the world.
My point is that you misrepresent my concerns. They are not based upon some "head in the sand" approach. But at least I think you would agree that I am entitled to express my opinions and that I should not be shuffled off to jail or fined for expressing them.

Michael Miersch - For the record.
The discussion of German denialist Michael Miersch was introduced into this thread by troll NorrisM @112 and in subesquent comments the trammels of Meirsch have been repeatedly highlighted by NorrisM as he considers denialists like Mersch have the right to set out their opinion without let or hinderence. This was not the view of the German Federal Environment Agency who in 2013 published a 120-page exposition titled 'Und Sie Erwärmt Sich Doch. Was steckt hinter der Debatte um den Klimawandel?' ('And yet it heats up. What is behind the debate on climate change') criticising German climate denial and naming Miersch and a couple of his colleagues. This naming is described as "unusual for a government agency" by Miersch (although without naming, it would be difficult to debunk any specific climate denier or instance of climate denial) who sets out a turgid account of (to quote Kenneth Williams) "infamy, infamy, they've all got it in f' me!" and how he and fellow denialst Dirk Maxeiner were taking the Federal Environment Agency to court to enforce a withdrawal of the government brochure. Sadly for Miersch, the German courts concluded that he was after all legally a Klimawandelskeptiker. His turgid account of all this was duly publshed by the Gentlemen Who Prefer Fantasy. I think it is fair to say that, unless a translation of the full 'Und Sie Erwärmt Sich Doch. Was steckt hinter der Debatte um den Klimawandel?' is forthcoming, the rights and wrongs of all this belong in a German-speaking forum and should not be trolled around at SkS.

I have appreciated you comments in other respects. I think we disagree on this point and perhaps we should just move on to other things. By the way, I think the first one to use the expression I used was Voltaire.

NorrisM @134
Thank's, but just on this sea level rise issue. You appeared to be quoting some panel discussion where Koonin asked some questions, and you were dubious of whether the IPCC had sufficient reasons for projections of one metre by 2100 etc. I'm mystified why you think the criticism or questions of one person is particularly significant, especially given Koonin has not put any real evidence on the table about sea level rise and why he might think IPCC have it wrong. I have provided you with IPCC explanations of why sea level rise is expected to accelerate, and I see others have done the same. Do you have any proper scientific evidence of why they might be wrong? You certainly havent provided any.
"My main point is that I do not think the politicians of the world, not just the United States, are really going to impose carbon taxes beyond what is politically acceptable so it is wasted time talking about imposing carbon taxes based upon theoretical calculations of SCC"
I agree it all has to be politically acceptable, and I have already said that Norris. You start with an appropriate lesser figure like California has and increase this over time. I think they had $30 but would have to check and it should possibly be a bit more. But this figure will have to be increased over time reasonably quickly.
But you have to consider the theoretical maximum to get the wider picture and context otherwise its hard to identify any starting figure.
"So my principal point is that you do what is politically feasible. Impose a carbon tax on the cost of pollution. "
No this seems wrong to me and a pretence that climate change doesnt somehow exist. It should emphasise both pollution and climate change. But I understand where you are coming from.
"The other thing to do is convince the public that wind and solar power (for now I am leaving alone nuclear power) can viably compete with FF, using FF as a back up source of base load power. "
Yes no question about that. I hear what you say about Trump and Republicans. I have no idea what will happen there the whole thing looks like a disaster area of epic proportions in every respect. I'm just personally interested in the science, and practical policy responses. Politics tends to be the art of the compromise. I can only advocate on what I think the scientific truth is, and the most sensible response to reducing emissions, and hope people see sense on the political side of things and try not to let partisan political emotion take control and instead think of the wider picture a bit more rationally.
"One final point, ensure that the carbon tax is dividended back to the people. If you keep it to distort the economy by investing it in RE then you lose half the electorate. "
I basically like tax and dividend. I think about half should be given back to the people and about half put into renewable energy and electic car subsidies. There are many reasons for this, and I dont have time to explain the rationale. But I dont see any reason to believe people would rebel, if some went into renewable energy. The Pew poll research you are so fond of quoting clearly found a majority were favourable towards renewable energy etc.
I just dont think R Toll has much credibility for reasons others have stated and my own reading, but $30 is a useful figure to at least consider. Personally I think a bit more as a starting point, but look at the risk of repetition, nobody is going to seriously suggest a whopping really high tax at day one, the world doesn't work like that.

NorrisM @146 ,
you are (I am sure, deliberately) failing to distinguish the right to advocate genocide/mass-murder , from the right to express innocent opinion.
I am reasonably certain that jurist Sunstein (whatever his provenance) would disagree with your view that "anything goes" for freedom of speech as Freedom trumps all considerations of common sense & morality.
e.g. The stupidity of the anti-science ideas of the Flat-Earthers is one thing (since it harms no-one) -— but the criminality of a steward advising Titanic passengers to stay in their cabins & to avoid the lifeboats . . . is something completely different. ~And it's not at all innocent.
Your position is indefensible, NorrisM. Please keep your trolling mode level to 75% or below ! Even though this thread is a broad umbrella ;-)

RedBaron@30, thanks for the additional links. Interesting points you make about how much the natural cycles could be helping us.
But my basic point is that whatever the land and oceans are doing to remove CO2, we are still building up CO2 at a net 2 ppm/year, which is disasterous. At this rate we are only about 20 years from the budget for staying below 2C. So whatever promises there are for using sequestration technologies, whether natural or artificial, we had better get busy using them. If modified farming practices can be used to sequester additional carbon, that would be great.
Thanks for pointing out a side of the discussion that I know I have been overlooking.

This has been said many times before but I am not defending what Miersch said but only his right to say it.
As soon as you start putting limits on what people say based upon your views as to what is right and wrong, you are just on a continuum with dictatorial regimes whose arch enemy is freedom of speech. One of the most important things necessary to protect our democracy is to allow people to have different views and to be able to express those different views. I am sure you have read 1984 by George Orwell. None of us want Big Brother watching.
You would do well to listen to the Sam Harris podcast I referenced and see if you do not agree after actually listening to Sunstein that Miersch should have the right to say what he says. According to Harris, Sunstein is the most quoted law professor in the United States. He is not a neo-con.
The attitude you express seems to be something that has invaded a number of university campuses in the US where students shout down anyone who disagrees with them and force university administrations to "disinvite" speakers from attending on campus. It is very troubling.

Red Baron, I was reading carbon rich soil is some Australian grass lands go down 20 metres, which indicates the potential.
But what do you make of this? looks ominous:
www.sciencedaily.com/releases/2016/09/160922085737.htm
"Soil will absorb less atmospheric carbon than expected this century, study finds". It appears to be saying potential is huge but its a slow process. Or is the study wrong or out of date?

NorrisM @141 , you deserve to be rapped over the knuckles for your misstatement about German journalist/denialist Miersch [see posts #114 and #129].
i.e. your quote: "He [jurist Sunstein] would strongly defend the right of Miersch to say what he wants as long as it does not promote physical harm to other persons." (unquote)
But that is exactly what Miersch is guilty of (as are all climate Denialists). He disseminates falsehood (and advocates inaction) which will promote physical harm to millions/billions of people during the course of this century & the next one.
That point is plainly obvious. Is it not, Norris?
But let us not bother to discuss the sad case of Miersch, here. (And I am not offended that you are espousing Miersch's position, for I realise you are in 75% trolling mode.)

@ Evan #29,
You said, "That is, the natural removal rates cannot keep up with our emissions."
You are correct. But I would like to point out the primary land based rapid removal of CO2 back into the long cycle is 99% destroyed by agriculture. Even secondary pathways are by vast majority destroyed by agriculture. Of course the rate is 100 times faster than can be removed and the sequestration rate is woefully inadequate. It's basically by all intents and purposes destroyed and actually turned into an emissions source instead, with a few rare exceptions.

Evan at 09:24 AM on 22 October 2017SkS Analogy 10 - Bathtubs and Budgets
aleks@27, perhaps I should respond to your comments as follows. No analogy is perfect, and certainly the atmosphere is not a closed system in the strict sense as you point out. But the point I am trying to make is that whereas pollutants are regulated in cities because of the locally high pollution that can result from high emissions, once emission rates are reduced, the outside winds flush the pollutants out of the city. In contrast, the effect of CO2 in the atmosphere does not depend on the rate at which we emit, but only on the total amount, because CO2 slowly builds up, and there is no ourside source to flush the CO2 away. Once we raise the level in the atmosphere, we are stuck with this concentration for a very long time, until the sinks to which you refer slowly bring down the concentration. These sinks act so slowly (i.e., 100's to 1000's of years) compared to the time scales that we care about (the lives of our children and grand-children), that effectively we are emitting CO2 into a closed system: once we emit the CO2 we are stuck with it for the future we care about.

aleks@27, thanks for some good points. Here are some responses.
Regarding the atmosphere being a closed system, carbon budgets developed by the IPCC account for the fact that the oceans and biosphere absorb much of the emitted carbon. The reason why I refer to the year-on-year increase of CO2 is that the yearly increase is the net effect of emissions minus uptake by the oceans and biosphere. The fact that CO2 is increasing over 100 times faster than any natural cycles in the last several million years is evidence enough that we are essentially emitting into a closed system. That is, the natural removal rates cannot keep up with our emissions. Again, IPCC estimates account for the effect of natural removal mechanisms in determining budgerts that represent the amount we can emit into what is essentially a closed system to stay below a specific warming.
Regarding H2O as a stronger greenhouse gas, yes it is. But the H2O increases in response to increases of CO2, and not independently. Again, IPCC estimates account for the fact that CO2 is the main driver and H2O simply responds. That is, the removal rates of CO2 are so slow, that we can easily build up CO2 concentrations by emitting more. This is not so for H2O. If we emit more H2O, it simply rains out in a few weeks. The only way to increase H2O concentrations is to increase the temperature of the atmosphere. Once temperature is increased by the CO2 emitted, then H2O increases as a response (i.e., positive feedback). The H2O increase for a given temperature increase is governed by the Clausius-Clapeyron equation.
Therefore, CO2 is still the driver, and H2O merely responds.
But thanks for your comments. It is good to get different viewpoints.

Some statements in the article seem to be inaccurate. "Earth atomospere has a finite volume". Does the author mean all the atmosphere which nominal borders are determined by amount of gases retained by Earth's gravity? Rather it's lower layer of the troposphere containing most of greenhouse gases. However, in this case the borders of the lower layer are also conditional because of uneven height distribution of different GHGs according their molar masses (for example, methane and CFCs).
"We keep adding GHGs into this closed system". The system is not closed: CO2 dissolved in fresh and saline water, absorbed by vegetation.
About relationship between the "budget of carbon" and "overall warming". It would be correct within the framework of greenhouse effect theory, if CO2 is indeed the main greenhouse gas. However, water vapor is stronger greenhouse gas than CO2: Th.L.Brown, H.E.LeMay a.o. Chemistry. The Central Science. Pearson. Prentice Hall. 4th Ed. 2009, p.781. Zerenboren & Kilpinen estimated the contribution of H2O to greenhouse effect of ~2/3: http://users.abo.fi/rzevenho/greenhou.PDF According to another source "water steam accounts for 36-70% of greenhouse effect". https://www.popsci.com/environment/article/2009-03/top-ten-greenhouse-gases#page-11 Moreover, in IPCC list of long-lived (only!) greenhouse gases: https://en.wikipedia.org/wiki/IPCC_list_of_greenhouse_gases the radiative forcing (rf) value of CO2 is only 0.63 of the total rf of all gases in the list. So, the contribution of CO2 in any case will be much less than 50%. That's why analogies between atmosphere and a bathtub, as well as between CO2 in atmosphere and water in a bathtub seem to be doubtful.

NorrisM:
I agree that current federal politics in the US represent a completely dysfunctional response to the risks of climate change, and getting Trump et al to change course is highly unlikely.
- It's "The United States of America", not "The State of United America", and individual states can and will take action. California is implementing a cap-and-trade system, for example (and partnering with Ontario and Quebec, last I heard). The whole premise of the article we are commenting below (I intentionally avoid the phrase "commenting on", unfortunately) is that other politcal pressures and actions are happening in the US outside the federal level.
- Europe is far more advanced that the US in implementing measures (although much more needs to be done), and although the US is still a major world economy it, does not need to remain one if it chooses not to.
- Although China is a huge carbon emitter, they are also rapidly developing alternatives. They will own the future if countries follow the US lead and hop off the bus.
- If the rest of the world decarbonzes, and the US does not, the US will become an increasingly unimportant player.
- As damages increase, political pressures can and will change.
I completely disgaree with your phrasing of "actual pollution costs (not an extended definition)". Your position represents a continuation of externalities that distort the economic costs related to fossil fuel use. Just because you want to label uncertainties in these costs as "vague", "theoretical", etc. does not mean that the best estimate of these additional costs is $0.
Your item 2 is more likely if we remove fossil fuel subsidies, and correct the distortions caused by the externalities. Your argument against assertive action amounts to "it's too hard", and the implicit choice is that you would rather deal with the consequences of letting climate change happen.
- That you keep repeating shop-worn denier talking points about uncertainty, models, etc. suggests that at some deep level you are still believing or hoping that the science is all wrong and no significant change is needed.
- From a position of risk management, I ask "what if the science is correct, and things are as bad (or worse) than the predictions? Do you have a plan that amounts to anything more than "I really hoped this wouldn't happen"?
As for your last point: monetary transfers to help developing countries is an active point of international discussion. It will be difficult, but I have not given up hope that the international community will find a solution.
- Remember: the best way to minimize the need for these transfers to areas that have been impacted is to prevent the damage from happening in the first place. Arguing about who will pay for the damage to the car is wasting valuable time that could be used to apply the brakes and prevent or reduce the collision.
Your position amounts to appeasement. Chamberlain did not achieve "peace for our time".

Bob Loblaw
Could you respond to my principal point that anything beyond what I am proposing is simply not realistic in the political environment existing not only in the US but in Europe?
To repeat, what I am proposing consists of two things:
1. Carbon Tax based upon actual pollution costs (not an extended definition) that does not exceed $30/t CO2; and
2. Measures within each country to change their energy mix from largely FF to a combination of wind and solar supported for base load power either by natural gas, hydro or nuclear power.
Attempts at asking the US, Europe or China to compensate all of the other countries of the world who will be impacted by sea level changes by imposing some very large carbon tax and distributiing these funds to the undeveloped countries of the world is not in the cards. Do you or do you not agree with this last comment?

"Still when you have time, NorrisM (and perhaps on another thread) it would be interesting to discuss why the Anglophone court system entirely fails to protect the public from the fake news and false information disseminated by the likes of journalist Miersch."
I agree this is not the place to discuss Freedom of Speech but you might want to listen to a recent podcast of Sam Harris (just finished listening to it) interviewing Cass Sunstein, a law professor at Harvard and a former official of the Obama administration. In that podcast he provides a detailed analysis of where the legal limits are on freedom of speech and the importance Madison ascribed to this in the drafting of the US Constitution. He would strongly defend the right of Miersch so say what he wants as long as it does not promote physical harm to other persons. Opinions on what should and should not be done should not be restricted by governments. It is a slippery slope.

MA Rodger at 04:07 AM on 22 October 2017Climate and energy are becoming focal points in state political races
HorrisM @132/133.
Thank you for clearing up your source. Do note that this question you quote is not "based upon the questions posed in the APS panel conducted by Koonin" or is it "Koonin is asking the question." The question was set by the APS Climate Change Statement Review Subcommittee (which was chaired by Koonin) as part of the Workshop Framing Document. The relevance of the question can perhaps be judged by it not featuring within the resulting workshop. Indeed, contrary to your insistence that it is, your implied interpretation of IPCC AR5 is not correct. Firstly, the question itself is not entirely factual. The required average SLR 2015-2100 would be 9mm/yr not the 12mm/yr presented in the question (a relatively small but worrying error) while the acceleration through the 20th century is reported in AR5 Sec 3.7.4 at roughly 1mm/century thus in agreement with the 0.01 mm/yr^2 described by the question (although a simple comparison between 20th century & 21st century accelerations is singularly naive, even tantamount to cherry-picking as explained by Bob Loblaw @139). But beyond these errors, the most egregious of all is your parroting of this somewhat misguided question as though it was not compatible with the AR5 projected 1m SLR by 2100. The question is first asking "What drives the projected sea level rise?" to which the answer is 'GMST' and then asks "To what extent is it dependent upon a continued rise in GMST?" to which the answer is 'pretty-much entirely but with the exception of the potential for the onset of large-scale grounding line instability in the marine-based sectors of the Antarctic ice sheet.' Your interpretation of the substance of the question as being incompatible with 1m SLR by 2100 is thus flat wrong. -
Bob Loblaw at 03:03 AM on 22 October 2017Climate and energy are becoming focal points in state political races
More math:
NorrisM: "...and an order of magnitude larger than implied by the 20th century acceleration of .01 mm/yr2 found in some studies (AR WG1 Report Section 3.7.4). "
Are you cherry-picking the lowest rate the IPCC found? Or are you using a source that cherry-picked the lowest rate?
Please look at the post over at Tamino's I referred to previously. The observed acceleration over the past 50 years is 4x the number you quote. (Was about 1.5, now 3.5; 2/50 = 0.04 mm/yr^2). The most recent IPCC report referenced earlier shows rates of acceleration closer to what you state when considering the entire 19th and 20th centuries, but Tamino's post looks more closely at recent changes. (And yes, under his real name, Tamino has published statistical climate data analysis in the scientific literature.)
In the IPCC AR5 chapter referred to earlier, it states "...acceleration continues throughout the century in RCP8.5, reaching 11 [8 to 16] mm/yr in 2081-2100."
-
Bob Loblaw at 02:40 AM on 22 October 2017Climate and energy are becoming focal points in state political races
NorrisM: "...would require an average rate of up to 12 mm/yr for the rest of this century"
Let's do some math. It is now 2017. There are 83 years left in this century.
- 83 years x 12 mm/yr = 996mm.
- The IPCC graph I posted earlier shows that current sea level rise was already about 0.25m above pre-industrial values in the year 2000 (+/-).
- 0.25, + 0.996m = almost 1.25m.
If we account for the fact that this claim (and the IPCC projection) was made earlier than 2017, the error gets worse.
Can you please, NorrisM, look more closely at the credibility of some of these sources? Koonin is not "factually correct".
...and the IPCC projections are not linear. Because they look at the physics, and project the results based on our current understanding of the link between temperatures, preciptiation, and ice sheet dynamics.

NorrisM:
Thank you for answering the questions I posed. They were not, however, rhetorical questions ("asked to make a point rather than to elicit an answer."), buth rather genuine questions asked as a sequence in an attempt to focus the discussion. Think of them more as the Socratic Method, searching for areas of agreement and areas of disagreement.
First point (minor) - I think you missed a question. There were 8, and you answered 7. I think that you missed one somewhere in 3-6, as your answers 6 and 7 look more like answers to my questions 7 and 8.
Second point: Koonin's statements about sea level rise. I linked to the full IPCC report chapter 13 in comment 122, In the table of contents, it lists the following sections:
13.4 Projected Contributions to Global Mean Sea Level
13.4.1 Ocean Heat Uptake and Thermal Expansion
13.4.2 Glaciers
13.4.3 Greenland Ice Sheet
13.4.4 Antarctic Ice Sheet
13.4.5 Anthropogenic Intervention in Water Storage on Land
13.5 Projections of Global Mean Sea Level Rise
13.5.1 Process-Based Projections for the 21st Century.
13.5.2 Semi-Empirical Projections for the 21st Century.
13.5.3 Confidence in Likely Ranges and Bounds
13.5.4 Long-Term Scenarios.
Your statement that "The IPCC report does not reconcile how they get to 1m if Koonin is asking the question" is simply wrong. The IPCC does give an extensive discussion of the literature regarding where these estimates come from. That leaves two possibiities, in my mind:
- Koonin is ignorant on this subject.
- Koonin is intentionally selecting certain forms of evidence and avoiding others in order to present a particular case.
Regardless of which of 1 or 2 is correct, Koonin has no credibility as an honest reviewer on this issue. #1 can be fixed by learning (on Koonin's part). #2 is much more difficult to change. You can, however, learn that some of the sources you are using are not trustworthy.
On question 2: yes, the IPCC may be wrong. Sea level rise by 2100 may be less than stated by the IPCC. It also may be more. There are people studying sea level rise that think the IPCC summary is too conservative - that there is a real risk of large ice sheet destabilisation by 2100 that will lead to 2-3m or more of sea level rise.
I will state again: a risk management plan that assumes all uncertainties will fall in my favour is a Bad Plan.
On answers 6 and 7:
- You say "another consideration is that this is going to occur gradually over a period of a few generations." . It is already happening now. It is going to get worse. Although it is impossible to say "this extreme weather event was caused by global warming", the number and frequency of such events is increasing according to many measures and attribution studies. What used to be rare events are now becoming common. Insurance costs are rising, and government emergency bailout funds are running deep in the red.
- Yes, Florida's real estate values may go down. People may rebuild elsewhere. People also may convince politicians to provide federal dollars and rebuild. That is what the current US habit is: federally-funded flood "insurance", which takes money from all tax-payers and gives it to the rich along the coasts.That transfer is a subsidy to those on the coast. The current market is already distorted.
- Now, what do we do about Bangladesh? Can they afford to move, and where to? You mention Lomborg: he might have an ounce of credibility if he actually was making an effort to improve lives through those other methods. He is not. He is a terrible role model, and he distorts many, many facts in presenting his arguments. He is not a credible source of information.
- You admit that the problem is global. It needs global solutions, and agreements such as the Copenhagen Accord are a step in the right direction. The U.S. has backed out, and the U.S. is risking being left behind. If the rest of the world decarbonizes and the U.S. ends up isolated, it may become the "developing world".
- On paying other countries to help them adapt vs. letting them move wherever they want. Refusing to pay, and refusing to let them move is basically telling them "I don't care what I've done to you, and I won't help in any way". If things get bad enough, you simply won't be able to stop them moving,and refugee problems will become far worse. We'll be faced with mass migrations, mass deaths, etc. Look at how many people already die trying to get from Cuba to the U.S. or across the Mediterranean Sea to Europe.
- You seem to focus on costs of dealing with the mess. Wouldn't it be nice if we could find a way to prevent the problem?
Nigelj resonds to you with the statement "Then you follow up with skeptical climate statements ". Here are some specific examples (quotes in italics), with my comments in []:
- "vague future costs."
- [Failure on your part to accept uncertainty and properly Risk Manage]
- "...based upon predictions of future temperature increases which are largely based upon models."
- [Failure on your part to understand how science makes predictions. Usually the skeptical myth "based on models" implies based on computer models, which is not our only source of information. If it means based on any sort of model, then unfortunately all of science uses models of one sort or another, so rejected models writ large means rejecting science.]
- "distorting our economy with a very large carbon tax.",
- [Failure on your part to understand that externailities are already a distortion. A carbon tax tries to remove that distortion.]
- " I do NOT think that a large carbon tax beyond the costs of pollution"
- [Failure on your part to understand that releasing CO2 and causing sea level rise, increased drought, increased heavy rainfall, etc. is a form of pollution.]
Throw in a few "China is a problem and China should pay" arguments, and you are reading from the Climate Denier's Playbook - although I'm sure it doesn't seem that way to you. You have trusted a lot of very unreliable sources of information, and it is affecting your view.

NorrisM at 01:58 AM on 22 October 2017Climate and energy are becoming focal points in state political races
nigelj @ 130
My main point is that I do not think the politicians of the world, not just the United States, are really going to impose carbon taxes beyond what is politically acceptable so it is wasted time talking about imposing carbon taxes based upon theoretical calculations of SCC. And they are theoretical when there is so much disagreement on what and what should not be put into the calculation. If you want an IPCC statement which effectively acknowledges this I can point to the section of Chapter 10 of the IPCC 2014 Report which I have read in its entirety.
Beyond the US, look what has been happening in the UK with Brexit and with the rise of ultra right wing parties throughout mainland Europe. Suggesting that carbon taxes will be imposed on these nations to compensate for future SCC in other parts of the world is close to fantasy. The Paris Agreement is the perfect example of how politicians operate. All the real cuts are after 2030 when these politicians are long gone. Meanwhile they get reelected based upon grandiose statements that do not cost their electorate in the pocket book.
So my principal point is that you do what is politically feasible. Impose a carbon tax on the cost of pollution. Of course China is onboard for this. If the Communist Party does not do something about pollution they will lose their grip on power. They know this.
The other thing to do is convince the public that wind and solar power (for now I am leaving alone nuclear power) can viably compete with FF, using FF as a back up source of base load power. Replace coal plants with natural gas which emits one-half the CO2 into the atmosphere. I appreciate that this last point is somewhat problematic with Trump in power but I do not think the Republicans are all in favour of coal.
One final point, ensure that the carbon tax is dividended back to the people. If you keep it to distort the economy by investing it in RE then you lose half the electorate. I reread section of the Lomborg book where he asks Richard Tol (I think he is an IPCC contributor) as to the "pollution cost" of carbon. I thought the range was $14 to $20/t. In fact, Tol uses the range $2/t to $14/t. I appreciate the low range of the IPCC for (I assume) pollution costs only is$18/t so I may be high on my suggested $30/t. My sense is that our economy can handle $30/t so I am not retracting that figure but I think that is the high end.

Hit the wrong button, here is full quote:
"The IPCC projected rise of up to 1m by the end of this century (depending upon the emissions scenario) would require an average rate of up to 12 mm/yr for the rest of this century, some four times the current rate, and an order of magnitude larger than implied by the 20th century acceleration of .01 mm/yr2 found in some studies (AR WG1 Report Section 3.7.4). What drives the projected sea level rise? To what extent is it dependent upon a continued rise in GMST?"
These were the questions provided to the participants prior to the oral hearing. Not all of the questions included in the Workshop Framing Document were dealt with in the oral hearing.
Obviously my calculation of 3 mm/yr came from the reference to "four times the current rate".
My point is that whatever you think of Koonin, you have to agree that this is probably factually correct as to what the AR5 WG1 report has to say about sea level rises.

NorrisM @128,
In your replies to questioning set you up-thread, you appear to be presenting an interpretation of IPCC AR5 findings on SLR as set out by Steve Koonin at the "APS panel". Your actual comment was:-
"Based upon the questions posed in the APS panel conducted by Koonin from information extracted from the IPCC 2013 assessment sea levels are rising at a rate of 3 mm/yr which translates to 9.8 inches on a "linear basis". The IPCC report does not reconcile how they get to 1m if Koonin is asking the question"
I assume from this you are referring to something within the 2014 APS Climate Change Statement Workshop [transcript] but I see nothing in this workshop that provides a basis for your comment.
Can you point to the source of this?
I would add that the Executive Summary of IPCC AR5 Chapter 13 sets out quite clearly the size of the projected SLR by 2100 under RCP8.5, this being 30% already occurred (as illustrated in fig 13.27 already shown in-thread @122) thus a 1m rise would require an average SLR of 9mm/yr for the remainder of this century. Thus I don't see much chance of this Koonin character and his questioning providing any coherent assessment. (Note the 1m SLR excludes certain contributions which AR5 assesses would probably not exceed "several tenths of a meter of sea level rise during the 21st century" were they to occur.)

This may be of value to you. It's the last IPCC report on the section on sea level rise.
www.ipcc.ch/pdf/unfccc/cop19/3_gregory13sbsta.pdf
It describes evidence for historic rise over the last hundred years approx., and also future projections to 2100, and also the basis for these projections. Simply put, more warming is calculated to cause higher rates of ice melt in Greenland etc, and thus an accelerating curve leading to possibly 1 metre at the higher end of expectations.
They say for example :"High confidence in projections of increasing Greenland surface mass loss."
In my opinion any cost on carbon or carbon tax has to factor in an evaluation of problems of sea level rise along with all other impacts of climate change. It may not be building sea walls, but there has to be some sort of evaluation of costs, and it would be arbitrary to pick and choose which impacts of climate change to include. You simply have to consider all impacts but obviously acknowledging they are estimates plus or minus.
Of course nobody would say impose that cost immediately tomorrow as it would cause too much disruption and problems, and as you say would be politically hard work, so you would phase it in. But given the limited carbon budget remaining it needs to be ramped up reasonably quickly.
You say how do we convince the public? Then you follow up with skeptical climate statements and make that job harder.
I dont see why you are turning the issue into something about helping the poor. Im a believer we should help the poor but climate change is a cost on everyone, not just the poor. There is also nothing to suggest money that would have gone into climate change emissions reductions, would somehow go into helping the poor and pardon my cynicism but I doubt it would.
Likewise talking about the politics of immigration gets away from, the issue and is verging on a straw man as well. The most likely pathway is countries will have limits on immigration. Such market's cant be completely open as the results are too jarring. However immigration is also healthy and should be as open as possible with reasonable numbers, provided it is regulated in regard so total numbers. dont get out of control too fast. Really the question of developed countries somehow compensating less developed countries over emissions and climate change issues has to be done more based on who is the biggest emitter and who is economically struggling just from a humanitarian and social conscience viewpoint. Neither should we pay for other countries foolishness or laziness, so it is always a balancing act.
