Hmm, if you are fixating on a outlier paper (Zwally 2015), then I suspect you are using extremely suspect sources for your information. Gravity and altimitry methods both have weaknesses (but different ones). A clever approach which reconciles the metholodies by a joint inversion of altmetry, gravity and GPS is Espanol et al 2016. Their approach demonstrates a sustained net mass loss of 84+/- 22 Gt/yr.
"How about helping the developing countries develop and solve an ongoing humanitarian crisis now that oh by the way is truly polluting the environment?" Why do you believe fixing climate (which is important way to help developing countries) is incompatiable with your perceived priorities?

Alchemyst coments about last summer sea ice extent. How about the current values?
NSIDC, February 6, 2018:
"January of 2018 began and ended with satellite-era record lows in Arctic sea ice extent, resulting in a new record low for the month. Combined with low ice extent in the Antarctic, global sea ice extent is also at a record low." (emphasis added)

Alchemyst @21
Right now nuclear is safer than other sources of electricity. I just wonder how the statistics will look if multiple third world countries have reactors. It wont take many accidents to radically change the statistics per mwhr.
But listen. I'm not firmly opposed to nuclear power in principle. I have always said its an individual countries choice on what suits them. I doubt nuclear will become prolific enough for my worst fears about safety to materialise, so Im not too worried over the issue.
I agree safety it is a public perception thing. But you can hardly blame people. Like I said, nuclear accidents are shocking, and have a sort of disproportionate effect on our consciousness. Its the same as the way some people respond to islamic terrorism, they go batshit crazy. In fact more people in the USA are killed by lawn mower accidents each year on average. But its the unpredictability of terrorism and its gruesome nature that scares people, and much the same can be said of nuclear accidents, because they are just so unpredictable, deadly and the contamination is both a real problem, and an insidious sort of thing psychologically.
However its hard changing human nature, and so on that basis I suggest the nuclear industry needs a "gamechanger" technology in terms of safety, something that really makes a fresh start. You can't blame the green lobby. The general public look at the issues for themselves.
You quote the example of China, and rapid progress with nuclear power. Ok fair enough. Obviously in a dictatorship they don't care about any public opposition like in the west. This is great for the nuclear industry, do you really want to live under a dictatorship? And this dictatorship has made a mess of their environment in other respects.
I also wonder how many safety shortcuts are made in China to build the reactors that fast.
Western countries are free market democracies. I like that on the whole. People have a right to protest and long may this remain. Safety standards are likely going to be better than China and if this slows down construction, "so be it".
Electricity generators in America for example make the choice of nuclear or wind power, and I think it should be left to them to make that choice. Do you think governments should force nuclear power on 1)the population, and 2) onto generating companies? Seems too draconian to me and not in line with western values.
Having said that, government has to ensure the electricity system is stable, and of course lines companies have to ensure stability of supply. NZ has legislation requiring generators provide adequate generation to cope with shortgages etc, so this forces the electricity companies to carefully consider all options. They will build nuclear - if they absolutely have to for stability of supply. But right now wind and solar are economically attractive options. But my point is this seems like a generally good overall framework of decision making, that balances a free market with the state ensuring there is fundamental stability of supply
Regarding Halfnium, I do not know enough to really comment. However I was reading an article the other day that the world only has 50 years of cobalt left (ok it will be more in reality, but you hopefully see the point). The point Im making is many minerals have limited reserves. If Nuclear expands radically, it seems a fair bet some of its metals requirements are going to get expensive. Of course lets be fair, this is not unique to the nuclear industry, but nuclear power uses a lot of specialist metals, and its another problem to add to an industry with problems.

Alchymst,
Proposed theoretical reactors that have never been built are not solutions.3 have been built 2 in Germany which the green lobby shut down and one in China (see refs in above post)
Abbott discusses the breeder reactors you propose.
No he does not he only dicusses liquid cooled reactors not gas cooled as I proposed
The fact that none have been able to run for significant amounts without problems tells us how likely it is that they will be useful in a reasonable amount of time.
The Julich demonstration reactor reactor ran for 20 years
Work out a timeline: if they have a design next week it will take them 5-10 years to build. Then it will take 5-10 years to determine if the alloys they have chosen can withstand the extreme conditions in the breeder reactor and if their complex purification scheme for the fuel will work (both unlikely).
China is loading the first reactor, 7 more are in various stages of construction on the site, see above post for referenceThen they will have to apply to scale up and buiild new plants which take 9-19 years to build from the initial proposal. It will be at least 5+5+9 = 19 years before the first plants will be on-line in 2037. That is too late, we need a solution that we can build out today.
see previos comment 1 is being loaded 7 more are in construction
Abbott used the diagram of elemental abundance to show that the elements needed for nuclear reactors do not work. He included a table of how much of these metals are currently in production and current reserves which you did not address.
Abbot for example used halfnium as a rare metal which was needed in a nuclear reactor. halfnium is used in submarines as cost is of litte object. Civilian reactors use Boron, Cadmium and silver for references see above. one of the references is for 14 year old schoolscience in the UK, so if children are expected to know this why the fuss about halfnium. The second ref is from the nuclear engineering department Berkley, California.
This data showed that there are not enough materials for your nulcear utopia. Apparently Berylium is one of the key short materials. I mentioned it above but it appears to have slipped your memory.
Beryllium is a reflector it is used for small reactors and for starters. It is not needed for large reactors. no reference but a bit of physics. Beryllium reflectors bounce back the neutrons into the reactor. For this to work the k infinity of the core material is greater than unity. If k infinity is greater than one then a sufficiently large reactor does not need a reflector, and does not need to infinite!
India's "thorium reactor" includes uranium to burn the thorium. In 2013 it was scheduled to fire up in 2014. In 2014 in 2015, in 2015 2016, and last summer (2017) in early 2018. It has not fired up yet. Placing all your money on an untried technology that is years behind schedule and even in the best case will not be ready in time is not a very good plan. Not very convincing.
The advanced heavy water reactor (AHWR) is one of the few proposed large-scale uses of thorium.[52] India is developing this technology, their interest motivated by substantial thorium reserves; almost a third of the world's thorium reserves are in India, which also lacks significant uranium reserves.
The third and final core of the Shippingport Atomic Power Station 60 MWe reactor was a light water thorium breeder, which began operating in 1977.[53] It used pellets made of thorium dioxide and uranium-233 oxide; initially, the U-233 content of the pellets was 5–6% in the seed region, 1.5–3% in the blanket region and none in the reflector region. It operated at 236 MWt, generating 60 MWe and ultimately produced over 2.1 billion kilowatt hours of electricity. After five years, the core was removed and found to contain nearly 1.4% more fissile material than when it was installed, demonstrating that breeding from thorium had occurred.[54][55]
https://en.wikipedia.org/wiki/Breeder_reactor
In any case, nuclear is completely uneconomic. Renewable energy is half the cost of nuclear.
If you cannot be bothered to find references to support your wild claims you should comment at anonther site where they do not care what absurd claims you make up.Sweet please try and stop insulting peoples inteligence

nigelj,
Nuclear safety is much better than other fuel/energy producers. The difficulties are public perception of these accidents. for example the THTR reactor that used thorium uranium fuel mixture was shut down regarding an accident that released a small amount of radiation outside the building. This was following Chernobyl and with the Green lobby, the German Parliament it was used as a pretext to shut the building down. The designs are currently being used for a scaled up reactor in China. The article fails to mention that the reactor is capable of using thorium fuel.

https://www.nextbigfuture.com/2017/04/china-has-started-loading-pebble-bed-fuel-into-new-reactor-which-will-begin-operation-later-this-year.html
Your point on contaminated land is probably the most pertinent, certainly in the west, as in order to maintain low radiological doses people are removed from the proximity of the leak, But you must remember that the biggest leak of artificial radiation occurred in the 1950s, 1960s during the bomb tests.
In the west the green lobbies are strong, but I do not hear much from these in places like China, Iran and Russia. They will carry on with their nuclear programs and ignore the West hesitation. There will not be problems with siting the reactors too close to population centres.
Unhampered by lack of energy resources these economies will grow and will get more powerful and so will be able to overshaow the West
. We are already seeing this in China which is becoming to dominate the far east and is busily influecing a lot of the countries in development inAfrica and South America. If the west do not thrive economically then the eastern block will overtake the western economies.ps here is a reference to the use of Boron insted of Halfnium in nuclear reactors
https://www.bbc.co.uk/education/guides/zpp4jxs/revision/2
what it pinot out is that it is taught to 14 year olds in Britain was ignored in Abbott and the peer reviewers

michael sweet at 02:10 AM on 22 February 2018Antarctica is gaining ice
Fishfear
According to the most recent summary by the US Global Climate Change Research Program, the official report of the Trump administration, for sea level "A rise of as much as 8 feet by 2100 cannot be ruled out." That would cause a loss of more than a trillion dollars of real estate in Miami alone. World wide hundreds of millions of peoples homes would be washed away.
Your unsupported claim that " Even during the most rapid ocean rise scenarios things will be just fine..." is simply false.
According to the National Snow and Ice Data Center, the sea ice around Antarctica has set record lows each of the past two years. The land ice is declining at an increasig rate according to gravity measurements.
Your claims are all simply false. Please provide evidence to support your wild claims.

fishfear at 23:12 PM on 21 February 2018Antarctica is gaining ice
I watch the video from years ago and giggle... "The unexpectedly rapid loss of land ice..." Assuming the maximum temps projected by the IPCC does this young man understand how long it would take for a even a 10% melt? Even during the most rapid ocean rise scenarios things will be just fine... The sky is not falling. How about helping the developing countries develop and solve an ongoing humanitarian crisis now that oh by the way is truly polluting the environment?
Moderator Response:[TD] That video from "years ago" was made only 2.5 years ago. In my response to your previous comment I gave you a link to a Scientific American article that references studies from last year, which you could read if you were sincerely interested in learning. That "young man" in the video was a PhD candidate with a large number of peer reviewed professional publications directly relevant to the topic he was speaking about in that video. (A remarkable number of publications for a PhD student!) Now he is a postdoctoral fellow. His degrees and postdoc all are directly relevant: physical geography, geomatics, spatial analysis, glaciology, permafrost science, and northern environmental change.
Meanwhile you claim you are "working on" a PhD and have failed to respond to the specific counters to your claims that I already provided.
The percent of land ice melt is not relevant. What matters is the absolute amount of water released by the melt. Someone actually enrolled in a PhD program in planetary geology would know that.
Read the post about how much sea level will rise. After you read the Basic tabbed pane, read the Intermediate one. Watch the two videos. Then read professional statistician (multiple peer reviewed publications on climate change) Tamino's explanation of a new paper supporting the existence of sea level rise acceleration so much that by the year 2100 sea level would be .654 meters higher than in 2005, supporting the projections of IPCC AR5's RCP 8.5. Then explore the Surging Seas site to see the concrete, practical implications of that amount of rise, but keep in mind that the amount of rise could be double that .654 meters which was only extrapolated from observations up to now, because the current acceleration easily could increase. Then explore the US Geological Surveys site on sea level. If you really are enrolled in a PhD program, you should be able to handle the AR5 WG1's Chapter 13 on Sea Level Change. To learn about impacts, adaptation, and vulnerability, read WG2's report.

fishfear at 20:45 PM on 21 February 2018Why remote Antarctica is so important in a warming world
NASA's Operation Icebridge... Please Google it and then ask yourself why a search of Skeptical Science has no mention of the on going definitive research that now shows the overall increase in Antarctica ice. One would think this would be at least worth a mention... Right?
PS I have a BS in physical science, a MBA and I'm working on my PhD in planetary geology. I'm NOT a warming denier I'm just convinced CO2's role has been overblown and like the proverbial squirrel, we have taken our eye off the ball and should be helping a billion plus people in the developing world live better lives and stop polluting our little blue ball.
Moderator Response:[TD] Entering "Operation Icebridge" in the SkepticalScience Search field at the top left of every page reveals several hits. So what? Googling yields a bunch of hits, at least the first dozen of which fail to even hint at any "definitive research that now shows the overall increase in Antarctica ice." But there is a very informative page that should be comprehensible to someone who is "working on" a PhD in planetary geology.
Entering "Antarctic" in the Skeptical Science search field yields many hits, including a response to the myth "Antarctica is gaining ice."
Perhaps you are fixated on Zwally's 2015 paper. A more recent (July 2017) Scientific American article describes more recent research than that particular Skeptical Science post does, explaining that most scientists who study Antarctic land ice believe that its net is loss, not gain. Perhaps even Zwally:
Zwally's study team claimed that if mass losses in West Antarctica continued to increase, it would only be a few decades before they overtook the gains in the east. Also, the team has additional, unpublished data showing the mass losses in West Antarctica have not only increased, but have tripled—at least from 2009 to 2012. Early data show 2016 might have been the tipping point at which losses in West Antarctica became so great that they equaled those gains in East Antarctica. That means Zwally's results might already be in agreement with others on the key point: this frigid land—one that holds the fate of much of humanity—is melting.
A sincere word of advice from someone who's already gotten a natural science PhD: If you really are working on a PhD in planetary geology, you need to search the literature more thoroughly and critically, and synthesize what you find. PhD quality work is a big step up from BS quality work.

I read what appears to be the same article referenced by John Hartz @111 but in New Scientist 10 Feb. "Rags to Riches. It's official we cant be wealthy without trashing the planet".
Anyway, great article, but sadly the article was just too short to really do the subject justice.
I have been debating sustainability, resource scarcity, etcecetera with some people on another website. I tell you a lot of things will have to change, or the planet will teach us some bitter lessons and force change. But its off the climate change topic. Anyway I remain an optimist.
This may be of related interest on economic growth and why we may be heading to reduced growth rates:
www.politico.com/magazine/story/2016/09/economic-growth-jobs-recession-slowed-technology-214220
I have the same basic belief as OPOF: we have to ensure everyone progresses, not just a few. There are many reasons for this, not simply compassion, there are security and economic reasons. It doesnt have to be relentlessly exact, but we need to be going in at least roughly the right direction.

We obviously have some similar interests. I have "Behave" by Robert Sapolsky sitting at home in Vancouver. Too heavy to lug down here. Instead I brought along Steven Pinker's new book "Enlightenment Now".
One of the interesting parts of spending some time down south (for us in Canada) is the chance to "rub shoulders" with some real Republicans. Last night we were seated at a restaurant by a retired internist and his wife from Oregon. They were clear Trump supporters but clearly acknowledging that Trump had personality disorders (sounds like Paul Ryan). But he actually described American society as an "eat what you kill" society and seemed happy with it. For a medical doctor to espouse this view was somewhat surprising and disappointing. His only justification for "gerrymongering" was "that is the way it has always been" (again very happy with it). Although we did not have time to get into it, I think he rolled his eyes when he (not me) mentioned climate change. So Trump supporters are not just the ones alienated from globalization. A little "anecdotal" but there are some pretty wide gaps in US society. He blames the media on both sides for the disconnect that has developed between Democrats and Republicans over the last 30 years. On the other hand, there was another couple from Washington state who, when they found we were Canadian, were very apologetic about the US and Trump. The fellow had a fleecy on with the word "Canada" emblazoned on it. He said he bought it in Vancouver and planned to wear it on their upcoming trip to Great Britain. Pretty scary to see this gap in the most powerful democracy in the world.

NorrisM @ 119,
I like your story of Bob Woodward and his "sole exception of Richard Nixon".
The story is somewhat dated now, for I gather Woodward has just recently added a "second exception".
All the same, it illustrates how those who are evil-doers can still believe (at least in some small part of their brain) that they they are working towards the public good.

Jef @3
I dont see where your lack of clarity is. The "article" is actually mostly on Antarctic ice loss, and the considerable dangers of this. You are missing this fundamental point. You claim its got no references, but its full of links.
I dont really know what you are referring to on technology. Theres a link to something on blended hydrogen, but its hardly the main point of the article. You seem a little off topic to me.
You say " I have personally worked on several biofuel, syngas, biochar, and other projects alongside university efforts over the last 10 to 15 years and none of them are still active, all were essentially failures or a net wash at best. In other words as much is saved as is generated."
Your claims of experiments are not compelling and are anecdotal. Provide a link so I can check. We have a highly profitable synthetic methanol plant in my country and biofuels are actually quite well established now.
"Most if not all “renewable” energy is 100% dependent on FFs. They are a FF extender at best."
Only in their production, and studies show they reduce CO2 over time. Refer below.
www.renewableenergyworld.com/articles/2010/09/the-facts-about-wind-energy-and-emissions.html
www.scientificamerican.com/article/wind-power-proves-effective-co2-saver/
You sir just post a lot of claims, but not much in the way of peer reviewed analysis, or something from a recognised mainstream science magazine to back it up.
Like Riduna says there are ways of reducing emissions significantly, and that is whats important. I have mixed thoughts about BECCS, and I posted something on some other article recently. The best negative emissions systems appear to be tree planting and soil sequestration of carbon. Soil sequestration can certainly be scaled up in physical terms, its mainly a question of relatively simple changes to farming techniques, incentives and education.
Regarding the antarctic (the actual point of the article) there are a lot of issues pointing at possibility of more rapid sea level rise than currently anticipated. I dont like the sheer number of possible problems when you combine the antarctic and greenland etc. This suggests use of the precautionary principle.

One Planet Only Forever at 13:54 PM on 21 February 20182018 SkS Weekly Climate Change & Global Warming Digest #5
John Hartz@111,
Thank you for the informative reference. It helps me better understand how 'competition to appear to be better off than others' developed desires/excuses for things that are understandably harmful to the future of humanity, Personal/Private Interests that are understandably unsustainable.
A nit-pick with the author's Headline. The play on words with Comfortable/Uncomfortable is cute. But the study is not about 'comfort'. The study's concern is “Humanity faces the challenge of how to achieve a high quality of life for over 7 billion people without destabilizing critical planetary processes.” (the opening statement of the abstract for the report). Comfort may be a part of the life satisfaction goal that is in the study. But it is a term that is wide-open to interpretation. And even if it was more precisely defined, how significant it is could vary a lot among the population, even among the population of a single nation.
The study is limited to evaluating measurements of what has developed in nations based on 2011 data. Admittedly, data is required for an analytical analysis. But the developed data pool is not the full spectrum of possible ways people can live. It is only the results of the current global domination of human activity by competitive materialism and consumerism. The result has been competition/fighting to develop perceptions of superiority relative to others any way that can be gotten away with, generally ruled by popularity, profitability or social/financial/warfare power. A different result would develop if helping to advance humanity to a sustainable better future was the understood measure of success and acceptability (a justified Golden Set of Rules/Goals globally understood and accepted by the majority of humans to increase the chances of a helpful result developing, such as the set of sustainability goals mentioned in the report).
The required changes to have a better chance of a future for humanity will not be developed in the same socio-economic-political 'attitude environment'. In fact, the evidence is that deliberate actions in opposition to such changes are to be expected to be able to unjustifiably win in the existing developed system.
A global change of understanding regarding what is acceptable will be required. Games of power, popularity and profitability with everyone freer to believe what they want and do as they please will not develop the required changes. In fact, the developed evidence measured in the study shows that people freer to believe what they want and do as they please in pursuit of Private Interest can be expected to develop less sustainable ways of living.
A second nit-pick is in the following quote in the article (and repeated in your comment).
"Unfortunately, the same is not true for other social goals that go beyond basic subsistence such as secondary education and high life satisfaction. Meeting these goals could require a level of resource use that is two to six times the sustainable level."
The study Abstract states 'life satisfaction' as the example of goals that requires high resources. The following quote is from the Abstract: “However, the universal achievement of more qualitative goals (for example, high life satisfaction) would require a level of resource use that is 2–6 times the sustainable level, based on current relationships.”
In the report the following is stated: “The social goals with the highest associated resource use, ranging from about two to six times the per capita biophysical boundary, are democratic quality, equality, social support, secondary education and life satisfaction.”It makes sense that those items are measured as 'highly achieved goals in high resource use nations'. But the correlation exists in the socio-economic-political 'attitude environment' that has developed. It is not a required correlation.
They are the Winner Nations of the competition to gather as much benefit as possible in the games people play. The fact that there is serious poverty in many of the Biggest Winner Nations exposes that there are serious flaws in the ways things have developed, flaws in the play of, or enforcement of rules in, the games/competitions.
Clearly, changing attitudes through global education can change the resulting development. But the real change has to occur among the perceived Winners. All of the most powerful, most popular, and wealthiest need to have their helpfulness/harmfulness evaluated, with penalties personally assessed accordingly.
Things boil down to needing to correct the incorrectly developed perceptions of "Life Satisfaction" and correcting the incorrect admiration for Masters of Illusion/Deception, the undeserving winners.
And everyone can understand that unsustainability is due to the total actions of the total population. So, although the total population is a concern, the developed over-consumption and highest harm creating ways of life of the 'Biggest Winners in the competition to be perceived to be superior to, or more successful than, others' can clearly be the real problem.
Also, the problem is not 'Nations', it is people who play to Win any way they can get away with, including deliberately attacking increased awareness and better understanding that would expose the unacceptability of the way they play the game, exposing how harmful they have been. Those type of people can be Harmful Winners in any nation (rich or poor).
The entire global population needs to be educated to admire and desire actions that help sustainably improve life for others (and sustainably means able to continue to be a help into the far future, only retired/replaced when a better sustainable way is developed). The converse is for the entire global population to understand the importance of no longer being impressed by anyone who tries to 'get ahead, Win a harmful Private Interest pursuit, in an unhelpful/deceptive/secretive way', no matter how powerful, popular, or rich they appear to regionally temporarily currently be.

Yes, activism by both sides can increase polarity but I think there needs to be distinction between right-wing activists and paid disinformers. Someone lying for money is not a moral actor.
Agreed too that there is good data suggesting general public is less polarized than elites but elites act to lead opinion so it matters. Also data the importance of the middle ground. The civil rights movement didnt convince hard line racists (still hasnt), but it did influence more flexible thinkers who in turn influenced the next level down eventually creating a new norm.

jef @ 3
I think your criticism of BECCS and some of the other ‘schemes’ you have come across is quite right. You may be interested in my comment here.
You sound very frustrated that their isn’t an instant cure to halt global warming. Well, there isn’t! But there are ways of significantly reducing our greenhouse gas emissions, such as transitioning away from coal fired electricity generation (in progress) electrification of transport (in progress) and increasing the efficiency with which we use electricity (also in progress).
I know they are not overnight cures but they are among several effective ways of reducing emissions. Over the coming decade you will see them beginning to work. We need to do more and I believe we will – because if we don’t? Well, as they say, ‘nothing concentrates the mind so much as the prospect of being hanged’.

Yes I did allude to the fact incrementalism doesn't apply to everything.
Growth in fossil fuels use, population and economic growth all looks exponential. Just out of curiosity would you consider that "incremental"? It doesn't seem so to me.
I think you have explained the the purity issue very well and its not meant to be taken offensively or as a bad thing in principle. I think it depends how its applied, and whether application has some sensible basis. I do also understand Norris point of view on it.
But I would suggest politics is being polarised by activists on both left and right and feedbacks set in. The leftists are seen as disloyal etc, and the right wing activists (tea party, heartland people) are seen as not caring about fairness, and evidence based science. Its all very unfortunate.
However I read an interesting article in the Economist that researched political attitudes with Americas population. The partisan division is much stronger between politicians and elite groups than the general population overall. Of course there are big red / blue partisan state divisions, and divisions within states, but the biggest divisions are in the leadership. Apparently many people in small town america voted on gut instincts on the leaders style and personality, rather than policy or democratic / republican divisions. This is all contrary to my impression. Complicated. But the polarisation is apparently more at the top than the bottom. Don't know what it all means, but its not good.
All the moral foundations in the theory seem to have value. It just seems to me all become toxic when taken to extremes, for example excessive authoritarianism. Children need authoritarian parenting to a point, but treating adults this way can go too far. However fairness seems unique and something that is more clear cut. It seems hard to say that unfairness is ever a good thing.
I have read some moral philosophy like aristotle, kant, mill, rand (please forgive me about rand, I must have been crazy).
I also have a book you may find interesting, but I have not read much of it yet: "Behave" by Robert Sapolsky. "The biology of humans at their best and worst". This was the main point in my replying to your post. You are a busy guy so I dont expect a reply. We are possibly talked out on the issues for now anyway.

I thought the article was long on words and short, to the point of non-existence, on cost and the benefits to farmers and electricity consumers.
The problem with “BECCS”, as with coal-fired electricity generation, is the essential element involving sequestration and secure storage of CO2. This requires capture of the CO2 produced at the combustion point. Technology enables about 80% of it to be captured. It then has to be compressed into a liquid so that it can be transported by pipeline to a burial destination. That destination has to be located at a site where the liquid CO2 can be pumped into geological strata able to hold it securely for millennia.
This process has been trialled and found so expensive that it increases the cost of electricity by over 50% and, as noted above, still results in some CO2 emissions.
The question not asked in the article is: Why would any sane financier invest in wood-fired electricity generation fitted with carbon capture and storage when solar and wind generators with energy storage have a lower capital cost and can sell the electricity they generate much cheaper – and do so without producing, let alone emitting CO2?

The language is far from clear. Broad generalizations completely without reference (the onus is on the authors of the article not me).
Simply stating there is a problem then saying we need to ...oh I don't know... make it less of a problem?
It is a life threatening catastrophe that requires massive world wide action NOW!
Where is the attribution to successful beccs operations that show the potential to scale…none. I have personally worked on several biofuel, syngas, biochar, and other projects alongside university efforts over the last 10 to 15 years and none of them are still active, all were essentially failures or a net wash at best. In other words as much is saved as is generated.
Most if not all “renewable” energy is 100% dependent on FFs. They are a FF extender at best.
Oh plastics… yes thats not a problem is it?
So yes… magical thinking/technocopianism. You sir are the problem not the solution. We need real solutions not just a slight adjustment of the dial. -

nigelj - while incrementalism is generally good in governance, we also have to be aware that nature doesnt follow those rules and shouldnt necessarily be a guide in all circumstances - particularly we have ignored incrementalism to begin with.
Norrism - in MFT, the purity foundation is also called sanctity. Maybe a better term? However, forget what the term is called, and consider more it's influence on instant subconscious judgements about something. This foundation is behind why racists consider themselves moral actors. It is also believed to behind the appeal to preserve virgin forest. There is no judgement involved here on the moral foundations. Sanctity is not immoral for instance. The binding moral foundations give a very clear evolutionary advantage. However, I am noting that there is a clear left/right difference in the influence of moral foundations.
Climate change opinions are now strongly influenced by identity politics in the US which is unfortunately rather intractable. Once something becomes polarized, then feedbacks work to increase polarization. It is all to common for left-wing activists to indulge in behaviour which alienates the right where what they do can be perceived as disloyal, disrepectful or even unclean. This is one of the feedback that creates or builds polarization.

I think we have pretty well exhausted this topic. But I think you agree that the use of the word "pure" has just too many contexts related to fascism and its modern version the "alt right" to be used in a conversation to describe conservative viewpoints on climate change. I think nigelj makes this point. There is an aspect of evil (whatever that term really means) in the views of fascists and their racist views that should have nothing to do with a discussion of climate change.
I once attended a fairly small gathering in Vancouver with Bob Woodward (in town promoting his latest book at the time I believe) where he expressed the view that of all the US presidents he had interviewed, notwithstanding their differing political viewpoints, they all had the best interests of the American public at heart with the sole exception of Richard Nixon.

Incrementalism seems like a good philosophy as a general rule. The problem Karl Popper has is there are far more exceptions than he is willing to acknowledge. That's just the reality.
However incrementalism is pretty applicable obviously to things like carbon taxes, provided we start right now. The longer its left, the shorter the window of opportunity becomes, and then there could be a need for a far more drastic solution to climate change, as panic sets in, and fossil fuel companies will really be feeling pain. New research has shown strong evidence of an acceleration in sea level rise over the last 20 years, and projecting that takes us to about half a metre by end of century. Now even just a small additional acceleration this decade or so will get to a metre or more and this is what models predict, conservatively.
And there was nothing too incremental about growing fossil fuel use. Looks more like an exponential growth curve to me.

if it was global temperatures that came back after a 5-year slumber with a new all–time record, you'd think it would be news at least somewhere on the planet.
Not so for Arctic sea ice, apparently. But I do agree with you that this omission is on Axel Schweiger & the PIOMAS project, who didn't want to do the math until February 8th. Journalists follow published facts from scientists, and when there is none, there's nothing to report.

Yes. In hindsight in terms of serious problems the decrease in sea ice area is probably more significant that changes in thickness / total volume. Its a problem for endless reasons as you say, and it also has large implications for N hemisphere weather patterns.
A lot of sinkholes are opening up in northern russia. I saw a fantastic video of this by a russian scientist, showing these things in detail, and also a lecture on the issue, but I just cant find it again. However I'm pretty sure it was releasing methane and also CO2 in quantity. Soil carbon can be metres deep. Wish I could find that video.

Speaking of carbon taxes...
INDUSTRY observers welcomed Singapore's soft start in its implementation of a carbon tax through an initial price lower than the range provided earlier by the government, though some affected companies continue to hope for benchmarks to be used together with the tax.
The gradual increase upwards will help companies to decide whether they want to pay the tax or spend on projects to reduce their carbon emissions, said Nanyang Technological University (NTU) department of economics head Euston Quah.
Singapore's carbon tax will start at S$5 a tonne for five years from 2019, and, following a review in 2023, eventually be raised to between S$10 and S$15 a tonne by 2030, said Finance Minister Heng Swee Keat.

NorrisM - I actually dont dispute incrementalism as a good idea. Would just like conservatives to take a first step - even killing FF subsidies is a good first step. However, as indicated, I also think we have used FF to breach incrementalism and are flailing to cope with consequences. If we want to rapidly reduce (30 year timeframe), then time to start was long ago.
"Purity" is just a word - teasing out its meaning in Moral foundation theory really means looking at how it is measured. I am not advocating using the word in framing (white supremicists do however, appealing to that foundation) but appealing to that foundation in environmental advocacy is effective for gaining wider support. eg clean air, preservation of "virgin" forest etc.
I have to thank my son's master's dissertation for making me aware of this and I am digesting the material on effective communication. Nonetheless, I feel it is pretty hard to have a dialogue when one side has little respect for facts or logic and leap to rhetoric and FUD instead.
Storage issues are tightly linked to the actual mix of generation available and the ability of the transmission network to move power from distant sources. Having any hydro is a plus, because you can do zero cost storage by holding back water when sun shines, wind blows, and generate from it when it doesnt. While a lot has been made of storage issues as an excuse for sitting on hands, in places where need is arising, I see a rush by technology to meet the need. One of the points of measures like banning FF from a certain date, carbon taxes etc. is to actually stimulate that technology development.

"...major reduction in greenhouse gases", "...reduce CO₂ levels now...", "...new ways to reduce CO₂ emissions..."."Wiggly wormy weasle words that muddle the truth."
They don't muddle the truth, because the language is clear enough and is based on what we know is possible. You also don't explain why you think the statements in the article muddle the truth, so you are just posting empty propaganda.
"technological innovations are providing new ways to reduce CO₂ emissions..."."There are currently none that have any prospect what so ever at scaling to a degree that is even 1% of what will be necessary, but don't let that stand in the way of "magic happens aka technology"
You give no evidence that these things can't be scaled up. Theres no technical reason because the technology exists. The only thing standing in the way is perhaps human motivation, but people have found the will in the past to tackle major projects. Of course nobody said it would be easy. Where does the article say it would be easy? So you are just posting empty cynicism.
Of course one other thing standing in the way are campaigns of climate science denialism and also attacks on renewable energy, mainly from self promoting lobby groups. Maybe have a look in the mirror?
"...a low-carbon future."Which is it, negative carbon/removing carbon in massive giga, trillion, mega amounts, or just lower?"
The article said low carbon, so presumably they mean low carbon. Humanity will always use fossil fuels for things like plastic manufacture, had you not thought of that?
"What is needed is speaking truth to the masses. Difficult? hell yes, but absolutely good will happen until we take on that herculean task first.'
Yes, and you are not communicating anything very well to the masses, because you make wild, one sided, unsupported, cynical claims.

Yes pumped storage is the main current bulk storage option. There is also molten salt storage associated with some forms of solar power as below.
www.solarreserve.com/en/technology/molten-salt-energy-storage
Bulk battery storage is actually technically feasible, but the cost is too high. However we have good certainty that battery costs will fall very considerably.
Im not a person who normally buys into some of the technology hype we see, however I think theres good evidence that battery costs will fall and numerous new technologies are already in working prototype stage such as aluminium batteries.
I just take a general interest in the climate issue, and I try to make considered statements, but theres never enough time to tackle every aspect in the detail it really needs. Im sure you find the same. I rely on people being smart enough to "join the dots" sometimes. My real point was storage options do exist already.

Are you also interested in the area covered by sea ice since this affects albedo, solar energy absorbed by the Arctic Ocean and its effect on thinning of sea ice? Continuing loss of albedo in summer (doesn’t matter in winter) means Arctic ocean warming which may prove problematic on 2 counts: coastal erosion and methane release.

nigelj @95 and 106
Firstly, in answer to your question at 106, I have a number of times indicated that I would be happy starting with US$20/tonne and even perhaps US$30/tonne and see what happens. For that reason I would not "sign on" to a possible $80/tonne tax until we saw what happened at $30. Again, I personally have no real idea what the right level of carbon tax should be as I suspect is the case for most on this website because none of us have the economic resources to make rational judgments on such an issue. If there is a "peer reviewed" paper on this I would be happy to review same. Governments have those resources so I will choose to trust our federal government in Canada on what level of carbon tax can work without "complicating the economy".
But given the additional information provided by John Hartz above, the carbon taxes implemented so far are not having the effect required just as I suspected. Having said this, the answer I assume is to give them some time to work. I am happy with that but time is not on our side in the view of many on this website.
But I have intended to ask you a question related to the following comment you made in 95:
"The storage problem is largely solved in terms of technology. Look at the huge Tesla lithium battery complex in southern Australia, that is now saving them money."
My understanding that with respect to "bulk storage" this statement is incorrect. The Tesla installation has not solved the bulk storage issue associated with wind and solar power so that "pumped storage" is still the only viable source of bulk storage at present.
This view is based upon the comments of other contributors on this website. I would be happy to be proved wrong on this.

Here's a synopsis of the harsh reality and hard choices that now confront the human race...
There are now so many of us on Earth that the planet just doesn't have enough resources for us all to live comfortably, which means we require a radical rethink of how we could start living within our means.
That's the conclusion of a new study which looked at 151 nations and found not a single one was running itself in a sustainable way – ensuring a decent life for its inhabitants without taking more than it gives back in terms of natural resources.
The international team of researchers has even put together a website showing how each country is performing in terms of balancing the well-being of its citizens against figures such as land use, CO2 emissions, ecological footprint, and phosphorus emissions.
"Almost everything we do, from having dinner to surfing the internet, uses resources in some way, but the connections between resource use and human well-being are not always visible to us," says one of the team, Daniel O'Neill from the University of Leeds in the UK.
"We examined international relationships between the sustainability of resource use and the achievement of social goals, and found that basic needs, such as nutrition, sanitation, and the elimination of extreme poverty, could most likely be achieved in all countries without exceeding global environmental limits."
"Unfortunately, the same is not true for other social goals that go beyond basic subsistence such as secondary education and high life satisfaction. Meeting these goals could require a level of resource use that is two to six times the sustainable level."

Scaddenp @109, I hadn't heard of the Moral Foundation Theory, but I had a quick scan on wikipedia. I think it sounds broadly correct, and agree with your comments. Many of these differences are known anyway as part of the general discourse.
I had heard of the "purity" issue associated with conservatives, in the sense that they react very strongly to bad body habits and things like homosexuality, where liberals do also react also but not quite as strongly. So I can believe right wingers would be concerned about very optically visible forms of air pollution.
Nixon passed some great environmental law, despite his other failings. But times have changed and Republicans seem prepared to scale back all environmental laws, possibly because the liberty, loyalty and authority "foundations" seem to now over rule the purity foundation? But Norris is possibly reacting to the purity thing more like Nixon did in the old days.
However the theory as a whole is many shades of grey, because liberals also dont like visible forms of air pollution.
I'm a consensus seeker. I recognise these sorts of moral differences between left and right, (as you probably already know) but prefer to see the gap closed. Wikipedia made the point we mistake these differences for evil intent. Unfortunately differences in America are starting to spiral out of control, and it looks like I'm on the wrong side of history, in a way.
However I would still hope that conservatives (and anyone else) see the CO2 emissions problem as a "dirty" form of problem, even if its invisible and odourless.

Nigel, you may have heard of Moral Foundation theory? Haidt? One interesting feature of it, is the observation across cultures that left-wingers make gut moral judgements based on just care and fairness foundations. Right-wingers also use what are called binding foundations (loyalty, respect for heirarchies/authority, and purity). The last one means you have right-wing more ready to deal with pollution than rising sealevel.

"My point was that if Germany, Sweden and France have not fully implemented the necessary changes to meet the Paris goals, there is a reason why they have not."
How about it takes time? But if you never start, you will never get there. The OECD report looked only at taxes and only to 2015. Post-Paris there has been a raft of additional measures, in EU and other places (but not Canada or US) and it remains to be seen whether these will be sufficient. In countries which dont have neoliberal governments, measures other than carbon taxes are acceptable to the electorate. If you dont want to advocate for those, then you had been be ready to advocate for carbon tax.
Disruption to the economy is inevitable - either from decarbonizing or from adaption to a new climate. Why would you not choose to take the cheapest route?

NorrisM @ 101:
The third "arbitrary group" was "or some other group", which gives you free form to explain why you are not part of the first two. I can't see why that has been so hard.
You say "To try to do some kind of "weigh scale" measurement of costs and benefits as between different groups would be impossible." That is exactly what economic analysis attempts to do. When they do it, they try to clearly state assumptions, and provide explicit definitions for the terms they use. DIfferent assumptions end up with somewhat different results, but they nearly all indicate that future costs will outweigh future benefits.
At this point, I can only conclude that all your attempts to say things like "bring the economy down", "materially damage the economy", "put the economy into trouble", "industries that would immediately suffer greatly ", "a massive transfer of wealth", "out of a job", "all those direct costs you allege", etc. really were just rhetoric, and had nothing to do with an actual cost/benefit analysis (which you now say is impossible).

"Again, to the extent we are talking pollution rather than the consequences of rising temperatures and rising sea levels I think measurements can and should be made."
Nobody here is likely interested in a carbon tax based purely on particulate emissions and their relation to lung problems. That's just a non starter, and too contrived for words.
And the public might find such a strategy confusing and devious.
It also doesn't make sense because theres a huge difference between health effects of burning coal, gas and oil. It would be a nightmare practically.
If anything, a carbon tax should include the effects of both climate change and something limited added on for respiratory health effects. And it just goes to show a carbon tax has several justifications.
However, just my opinion, others may disagree.
Norris M @104, you are just spamming, and repeating yourself.
You have also not answered my question: do you accept a carbon tax and dividend scheme starting at about $30, and ramped up to about $80?

NorrisM: I posted a link to the Reuters article about the new OECD report as a commenter and author of the OP, not as a Moderator. For your edification here is the complete OECD news release that prompted the Reuters article.
Governments should make better use of energy taxation to address climate change
14/02/2018 -Taxes are effective at cutting harmful emissions from energy use, but governments could make better use of them. Greater reliance on energy taxation is needed to strengthen efforts to tackle the principal source of both greenhouse gas emissions and air pollution, according to a new OECD report.
Taxing Energy Use 2018 describes patterns of energy taxation in 42 OECD and G20 countries (representing approximately 80% of global energy use), by fuels and sectors over the 2012-2015 period.
New data shows that energy taxes remain poorly aligned with the negative side effects of energy use. Taxes provide only limited incentives to reduce energy use, improve energy efficiency and drive a shift towards less harmful forms of energy. Emissions trading systems, which are not discussed in this publication, but are included in the OECD’s Effective Carbon Rates, are having little impact on this broad picture.
“Comparing taxes between 2012 and 2015 yields a disconcerting result,” said OECD Secretary-General Angel Gurría. “Efforts have been made, or are underway, in several jurisdictions to apply the ‘polluter-pays’ principle, but on the whole progress towards the more effective use of taxes to cut harmful emissions is slow and piecemeal. Governments should do more and better.”
In 2015, outside of road transport, 81% of emissions were untaxed, according to the report. Tax rates were below the low-end estimate of climate costs (EUR 30/tCO2) for 97% of emissions.
Meaningful tax rate increases have largely been limited to the road sector. Fuel tax reforms in some large low-to-middle income economies have increased the share of emissions taxed above climate costs from 46% in 2012 to 50% in 2015. Encouragingly, some countries are removing lower tax rates on diesel compared to gasoline. However, fuel tax rates remain well below the levels needed to cover non-climate external costs in nearly all countries.
Coal, characterised by high levels of harmful emissions and accounting for almost half of carbon emissions from energy use in the 42 countries, is taxed at the lowest rates or fully untaxed in almost all countries.
While the intense debate on carbon taxation has sparked action in some countries, actual carbon tax rates remain low. Carbon tax coverage increased from 1% to 6% in 2015, but carbon taxes reflect climate costs for just 0.3% of emissions. Excise taxes dominate overall tax rates by far.
“The damage to climate and air quality resulting from fossil fuel combustion can be contained, but the longer action is delayed the more difficult and expensive it becomes to tackle this challenge,” Mr Gurria said. “Aligning energy prices with the costs of climate change and air pollution is a core element of cost-effective policy, and vast improvements are urgently needed. While in some cases compensation for higher energy costs faced by households or firms may be deemed necessary, especially to those more vulnerable, lower tax rates or exemptions are not the way to provide it – targeted transfers should be favoured.”
Further information on Taxing Energy Use, including graphical profiles of energy use and taxation in the 42 countries is available at: http://oe.cd/TEU2018.
An embeddable version of the report is available, together with information about downloadable and print versions of the report.

Where did I say anything about comparing Germany, Sweden and France on the one hand and North America on the other?
My point was that if Germany, Sweden and France have not fully implemented the necessary changes to meet the Paris goals, there is a reason why they have not. And the best guess is that the politicians are concerned that the required changes would bring with them substantial changes to the economy that would not be accepted by their electorates. I used the term "harm the economy" but if you want to say "significant changes to the economy" then so be it. But if these changes were not costly changes (or impractical at this time) I am sure Angela Merkel would moved on them by now.
Governments are clearly taking steps but they will not be sufficient to meet the Paris goals. As noted by the Moderator, the OECD has so much as said that. But they are doing what they can based upon political realities. Nothing profound here but it is stating the obvious.

My apologies. Your question was obviously not a yes or no answer. My answer should have simply stated that I cannot pick one of your arbitrary groups. We simply have to let the chips fall where they may on a cost/benefit analysis (outside of pollution costs) when it comes to the use of fossil fuels over the last 150 years because all groups however you classify them have benefitted. To try to do some kind of "weigh scale" measurement of costs and benefits as between different groups would be impossible. Again, to the extent we are talking pollution rather than the consequences of rising temperatures and rising sea levels I think measurements can and should be made.

Norris M made the claim that fossil fuels reduced poverty, and so on.
They have in a broad sense over time, and nobody disputes that fossil fuels have been a benefit in the past. Quite what this has to do with the issue at hand eludes me. Asbestos was a great benefit, until we discovered it had serious problems.
Anyway, its also misleading to claim the reduction in third world poverty since the 1980's (related to the numbers in MA Rodgers comments) is somehow a miracle caused by using fossil fuels. Eonomists say its strongly related to free trade and more open investment. (Something else America seems determined to dismantle).
And progress is driven more by 'energy', and we have options.
Ironically its arguably more practical to drive poverty reduction in Africa with solar power anyway.
