  1. Did Murdoch's The Australian Misrepresent IPCC Chair Pachauri on Global Warming?

    Thanks Dana. It looks to me that variability even year to year is absent - smoothed data or is the heat gain actually approaching continuous? To my mind this or similar graphs ought to be amongst the first referred to whenever a climate scientist is asked whether warming has paused, slowed or is not statistically signifant over the past x no. of years. Even before referring to Foster and Rahmstorf's adjusted temperature - or the visually compelling variation used by Kevin C www.skepticalscience.com/16_more_years_of_global_warming.html

    Why SkS withdrew from the Bloggies

    Eklectikis,

    You don't appear to understand the science well enough to make the statements that you are making.  I'd suggest you invest a lot more time in studying the actual science, and a lot less time reading WUWT, Curry, Spencer and Pielke, who don't actually communicate the science, but instead spend all of their time commenting on the politics and the 'debate' and sowing doubt in the science.  You don't need opinions, you need facts.

    I would also point out that Skeptical Science does not spread the official position coming from the IPCC.  It merely communicates the science itself.  Occassionaly, the site quotes the IPCC Assessment Reports, but more often than not, SkS directly presents and references actual scientific studies (which are also the basis of the IPCC reports).

    Or are you simply trying to say that SkS and the IPCC reports are based on the actual science, while sites like WUWT clearly are not?

    That story from Feynman, which I hadn't heard before, is a nice counterpoint to Ernest Rutherford's popular quote that a scientific discovery has no merit unless you can explain it to a barmaid.

    Since Eli brought up Groucho, my favourite quip is: "Why, this is so simple a five-year-old child could understand it! [aside] Go find me a five-year-old child; I can't make heads or tails of it.".

    China Takes a Leading Role in Solving Climate Change

    I've said many times, much of China's current energy consuption is the direct result of production of goods for western markets.  So, on a very real level, a portion of China's emissions are actually our emissions.  

    I'm hearing a lot of talk on both sides of the Pacific about manufacturing moving back to the US, so that energy consumption for manufacturered goods is headed back this direction.  And I think that's a good thing.

  5. China Takes a Leading Role in Solving Climate Change

    Phew, actually quite heartening - thank you!

  6. Why SkS withdrew from the Bloggies

    Hi shoyemore.

    I'm reasonably sure that Feynman would not support creationism, aether... Also reasonably (judging by his pragmatism, his taste for empirical verification of theories, and their detachment from the powers that be) I think that would be pretty critical of the IPCC, and specifically with the climate projections to, say, one hundred years from now... is this that bad?. But we have no idea, and we never will. Anyway, I brought Feynmann only to ilustrate the "no pejorative" meaning of the word pseudoscience in that context, that's all.

  7. Reality Drop - using social media to rapidly respond to climate misinformation

    Tom Curtis @ 13, you must excuse my ignorance as to what's hot and what's not in Baptist circles.  But I think the original reason for my interest in this isn't significantly altered.

  8. Why SkS withdrew from the Bloggies

    Apologies mispelling Feynman as Feynmann - mixup with Gell-Mann. They are no relation!

    One story about Feynman illustrates his approach to science. After his Nobel Prize was announced, a taxi-driver recognised him.

    "Hey, what did you get the Prize for?" ask the driver

    "Bud, if I could explain it to you before the end of the journey, then it would not have been worth a Nobel Prize" answered Feynman.

    It seems a strange attitude for someone who was (arguably) the greatest public lecturer on science ever. But he did not believe in Idiot Guides, and it is a questionable assumption that he would have taken to the world of science blogging and "Post-Normal" science that deniers try to push.

  9. Why SkS withdrew from the Bloggies

    Ecklecktius,

    I notice deniers fall over themselves trying to claim trying to claim Richard Feynmann as a talisman. Feynmann was a sardonic, intellectually tough individual who could flirt with Californian wackiness and keep his science straight. Somehow, I do not see him falling for Tallbloke's espousal of the luminiferous aether or Dr Roy Spencer's Creationism and membership of the Cornwall Alliance. Nor do I see him buying into the conspiracy theories purveyed on WUWT or Jo Nova.

    Feynmann was rather conservative and elitest when it came to science. "Post-Normal science" would have been alient to him. He believed in following observations rigorously, inter-scientist discussion and peer-review. I think he would have joined his friend, fellow-Nobelist, colleague and rival Professor Murray Gell-Mann in speaking up for the traducing and betrayal of science by both fringe figures and Establishment politicians.

  10. ‘Frozen Dirt’ and Methane … ‘We Cannot Go There’

    How do we stop the methane and carbon dioxide that is already escaping from permafrost areas, bubbling up from these pristine lakes and the invisible releases from other areas of permafrost?

  11. ‘Frozen Dirt’ and Methane … ‘We Cannot Go There’

    More detailed press release of the most interesting detail of this video: 1.5C being the "tipping point" of the large PF melt (based on the stalactites growth radioactive dating by Anton Vaks) can be found here in Oxford Uni press in Science 21 Feb 2013, DOI: 10.1126/science.1228729if you have an access.

    Interesting study worth close attention. Confirms Jim Hnasen's opinion that "danegerous" level of global warming is not beyond 2 degrees: we should limit it to 1 degree to avoid the "danger".

  12. Did Murdoch's The Australian Misrepresent IPCC Chair Pachauri on Global Warming?

    Ken @92 - our data are based entirely on measurements.  Ocean heat content was measured by expendable bathythermographs before the ARGO network was built.  The data are sparser in the past, particularly for the deeper ocean layers, but the data exist nonetheless.

    Did Murdoch's The Australian Misrepresent IPCC Chair Pachauri on Global Warming?

    Tom Curtis:  In your reply to my  reference to Lord Monckton's use of the Australian's version of Pachuari's views, you comment on "skeptics" silence on Monckton's views.

    He is indeed too rich for some "skeptics" liking, including Australian Senator Barnaby Joyce and conservative columnist Janet Albrechtsen:

    Christopher Monckton, 3rd Viscount Monckton of Brenchley, the eccentric UK climate sceptic, is proving too hot for some of Australia’s most prominent climate sceptics — including Barnaby Joyce.

    Joyce, who famously said that climate change sceptics were being treated like holocaust deniers and likened environmental campaigners to eco-Nazis, believes Monckton is on the fringe of the debate and unhelpful to those who question human induced climate change...

    On Wednesday conservative columnist Janet Albrechtsen in The Australian wrote that Monckton was an extremist in his language and is hurting the cause of those who want to ask hard questions of the science.

    ‘Frozen Dirt’ and Methane … ‘We Cannot Go There’

    Schaefer has said that permafrost tipping pt might be only 15 years from now. That was before some new research in Feb this year showing that permafrost carbon exposed to sunlight turns into CO2 40% faster.  All of which is to say: time to wound down the use of fossil fuels.

    Living in Denial in Canada

    Nice work Andy. Public surveys show that +80% of Canadians want their environment protected EVEN if it slows economic growth or costs them money. (Environics Research pdf)

    I wonder if denial is truly at heart of the matter or simply lack of awareness that Canada is fouling its own nest and profitting from what might one day be known as 'the crime of the century'?

    2013 Arctic Sea Ice Extent Prediction

    First posting on this website. Greetings to all.

    My estimate for 2013 minimum ice volume is 2221 km^3 based on the steepening trend seen in the last 6 years of the PIOMAS graph. If assymetric error margins are permitted, I will say +2500/-500 km^3 based on 2500 being roughly the amount of lumpiness in that section of the graph and -500 on an unsubstantiated hunch about the most northerly part of the ice sheet being the hardest to melt.

    Based on the earlier mention that research crews are now having to 'hunt' for ice thickness of 2m and taking that as a crude average thickness, my prediction for ice extent works out to 1,110,600 km^2, or a radius of ~595 km, if it were perfectly centered on the pole (c.f. ~700km from north coast of Greenland to the pole).

  17. Why SkS withdrew from the Bloggies

    (Sorry about the poor grammar. Hopefully it's not too difficult to amend my syntax on on the fly)

    "It would have been enough to post here making the point that the Bloggies' science awards are about popularity and/or fanaticism, and eschewing the nomination without actually withdrawing. (Had SkS won and thereafter publicly reiterated this position, that would have been a stronger, as well as good-natured, stand)"

  18. Why SkS withdrew from the Bloggies

    The principle for SkS has nothing to do with the awards criteria. Withdrawing misses the point in favour of declaring a preferred context (quality, not quantity). The woeful 'skeptic' blogs are ideological in nature and political in motivation. Pulling out is also political. It's a protest, isn't it?

    It would have been enough to post here making the point that the Bloggies' science awards are popularity and/or fanaticism, and eschewing the nomination without actually withdrawing. (Had SkS won and thereafter publicly reiterated this position, which would have been a much stronger, as well as good-natured, stand) I don't think any use is served by withdrawing. It won't change anyone's mind in the denialist camp, or fence-sitters. Indeed, it will more likely reinforce the 'skeptics' and look like sour grapes to more neutral types. The defense of science by protesting a popularity contest? I don't think it's a good decision.

    Why SkS withdrew from the Bloggies

    'Best anti-science blog' does have a certain ring to it. Isn't it just so... quaint that the typical Watts sycophant thinks they're doing 'real science', and that all the actual climate scientists are corrupt losers who can't even manage to walk and chew gum at the same time? Dunning-Kruger writ large, with a generous helping of right wing authoritarianism on the side (cyber bullies is what they actually are).


    What I like best is that a lot of their armchair theories contradict each other, but they rarely call each other out. As long as it goes against established scientific findings regarding AGW, it's OK by Anthony. He's becoming more strident by the week, and it's long past the point of descending into farce/jumping the shark.

  21. Reality Drop - using social media to rapidly respond to climate misinformation

    brent @12, whether an obscure American journalist or the most renown English preacher was the author of the quote is easilly checked.  The facts are, although the quote is often attributed to Twain, no such attribution also cites a source.  In contrast, it is to be found in black and white in a book published by Spurgeon in 1858 (page 74).    Spurgion writes:

    'It is well said in the old proverb, "A lie will go round the world while truth is pulling its boots on."'

    As I presume Spurgeon was not lying, it follows that neither Twain nor Spurgeon were the author of the quote, though apparently Spurgeon was the first to put it in print.

  22. Reality Drop - using social media to rapidly respond to climate misinformation

    Alces @ 5 and John @ 5.  I'll leave it to readers to consider whether the pithy quotation is more likely to have been coined by an obscure English Baptist preacher or his almost exact contemporary, one of the best humorists of all times.  But the reason I was interested in the attribution is that it's given as Mark Twain when the quote is used as the heading to chapter 12 of a tome entitled, 'The Hockey Stick And The Climate Wars'. The copy I have in front of me claims the author of this is a certain Michael E Mann.

  23. Did Murdoch's The Australian Misrepresent IPCC Chair Pachauri on Global Warming?

    Wide use of surface air temperatures as the primary measure and indicator of global warming is an ongoing communications problem. The excessive focus - it seems to me, even by climate scientists - on a measure that has high levels of internal variability allows and encourages the false perception that anthropogenic global warming is an intermittent phenomena. When the strong desire to find cause to disbelieve science on climate - without the genuine skeptic's desire to be well informed or truthful or fair-minded - the idea that the world is not currently warming gains traction. Measures of heat content such as the graph used clearly show that warming has not slowed or paused and looks like a better representation of the ongoing fundamental change to our climate system - yet it is surface air temperatures, not overall heat content or top of atmosphere changes that get the attention.

    But - how much is the Nuccitelli graph based on direct measurements? Even if the data record for ocean heat content doesn't go back as far as air temperaures accurate data about recent changes to ocean and overall heat content should help to put to rest the "pause in warming" misunderstandings.

    Tom Curtis- Thanks for the info, I was under the mistaken impression that The Weblog voting allowed an individual to vote once per day for the open period of voting,which could allow for a zealous group to bombard the poll way beyond the relative popularity of their choice. Maybe I was confusing their poll with another blogs poll,or maybe they changed their methods at some point. Thanks again.

    Magma:

    I didn't intend by my wording to imply that I didn't believe you as to the source of the quote. Exactly who said it wasn't relevent to my criticism of the statement, so I just didn't bother trying to verify it.

    If I were writing a scientific paper, the correct way to reference the quote would be something like "the founder of the bloggies posted ...(as quoted by Magma, in comment X)". I don't have direct knowledge of the quote myself, so I didn't want to say "the founder said..." without qualification - so I chose the wording I used to indicate that my knowledge was based on your statement, rather than me seeing the post myself.

    Sorry for the confusion.

  28. Why SkS withdrew from the Bloggies

    tmac57 @49, the Bloggies already have a mechanism to avoid multiple voting by a single person.  From their site, there mechanism for doing so is to restrict voting to one vote per email account, which is easy to game.  Never-the-less, finding a more effective method would be difficult.

    The problem with the Bloggies science award is that best is not the same as most popular.  WUWT is more popular than Skeptical Science because it tells a lot of people exactly what they want to hear, while Skeptical Science requires that you think (an ever unpopular activity).  That means Skeptical Science has far better content than WUWT in terms of scientific accuracy, so it is a better science blog.  That can be seen in the fact that it has recieved an award judged by scientists, and is used as source material in several university level courses.  Yet on any strictly popularity based contest, WUWT will beat Skeptical Science.

    What is worse, however, is that there are general science or technical blogs that are far more popular than WUWT that still do not win because, as it turns out, their readers are not motivated enough, or their writers do not respect the bloggies enough to ask them to, vote for that blog on the bloggies.  The Bloggies uses an unscientific polling method to determine the winner of each category, and unsurprisingly, as a result gets nonsense results for its "Best Science" category (and probably in other categories as well).

    As the owner seems uninterested in correcting the problem, he has confined his award to irrelevance.

    For Psychology Research, Climate Denial is the Gift that Keeps on Giving

    [N.B.  A new arrival to this blog, driven by hoards of denialists and trolls pretty much everywhere.  Retired physics prof, mostly lurker, rarely comment.]

    Delighted to see the recursion infinite loop on CT/denialism explored quantitatively! Still in my own infinite loop with internal debate on (A) DNFTT vs. (B) responsible engagement with scientifically honest critiques.  My own discriminator between the two just isn't able to keep pace with the rapidly propagating rage.

    Greatly appreciate the calm, rational insights from most regular commenters.  Also grateful for the moderators!

  32. Why SkS withdrew from the Bloggies

    DSL @50 and Bob Loblaw @54, there is a link to the Guardian article quoting the founder of the Bloggies in the first paragraph of the lead post.

  33. Why SkS withdrew from the Bloggies

    Climate4All gives a quote (s)he attributes to Truzzi that says:

    "Evidence in science  is always a matter of degree and is seldom if ever absolutely conclusive. Some proponents  of anomaly claims, like some critics, seen unwilling to consider evidence in probabilistic  terms, clinging to any slim loose end as though the critic must disprove all evidence  ever put forward for a particular claim."

    ...and then immediately follows it with a sentence that says

    "If we allow ourselves to diminish doubts,by black balling, name calling and unwilling to consider that science is unsettled,"

    ...in which "unsettled" is used as an absolute, without regard to the probablistic nature of "unsettled". Apparently, in Climate4All's view of science, the failure to provide absolute conclusions means things are "unsettled". This is a spectacularly useless definition of "unsettled", and is part of the "Merchants of Doubt" playbook that tries to pretend that little is known about [climate] science. Noone that has seriously read the IPCC reports or the climate science literature can pretend that real scientists ignore the uncertainty in the science. The claims of certainty and unwillingness for self-criticism and true skepticism are far more common on the "it's not happening, and we're not causing it anyway" side.

    AFAIK, physicists haven't come up with a Unified Theory yet, and an explanation of what causes gravity, but I sure as heck advise against jumping off a tall building without a parachute as a means of demonstrating that the science of gravity is "unsettled".


  34. Why SkS withdrew from the Bloggies

    Magma attributes this to the founder of the Bloggies:

    "But it seems that science blogs would rather complain about the results than try to submit nominations themselves"

    To me, this is analagous to putting up a bird feeder to attract pretty birds, having nothing but squirrels show up to eat the feed, and then saying it's the the fault of the birds. I suppose it's an easy out when one doesn't want to make any effort to design a bird feeder that is more attractive to birds and doesn't let the squirrels in.

  35. Living in Denial in Canada

    Ray@9, I am not forgetting population expansion

    I hope the third-world people have the desire to raise their standard of living, but I don't know to what extent it is true

    To see the world I would like to see in 2050, it would be absolutely necessary to raise their standard of living, but this needs to be done by leapfrogging the old model of technological progress and providing distributed clean energy sources on a massive scale. There exist analyses indicating that this is technologically and economically feasible.

    We have been able to adequately feed the entire world population for at least the last twenty years but have not done so: political will and/or skill has been lacking. Perhaps (maybe most likely) the 2050 I envision also will not happen because of lack of political will and skill.

  38. Why SkS withdrew from the Bloggies

    Well, I can agree with a good part of your discourse (DSL #47). But I read often people like Roy Spencer, Judith Curry, Roger Pielke Sr. and is difficult to me accept that they are "denialist" or that  their blogs are pseudoscience. I can accept they are wrong just in the same way that you can find mistakes here in Skeptical Science, but cross that line seems to me at least an exaggerated position.

    Yeah, I am aware that Climatology can be everything but "soft", my impresion is that some of the essential mechanisms have been well explained, and there is a good consensus in some directions. But everyone knows there is many other issues that remain unexplained, and the scientific dispute is perfectly legitimate. SkS (and many others at several levels) spreads the offitial position coming from IPCC, and others (also in an heterogeneal mixture) broadcasts other views... Can anything be more healthy? Mi answer to this question is that "no way".

    Said this, coming back to the Bloggies, I think that SkS should not have resigned, they/you have nothing to loose, and at least one thing to win: place a pro-IPCC blog between "the best" Science Blogs. People arriving to that list could compare, and ultimately change their vote for successive years. Now they will see only one side of the discussion, and this is always a bad thing. IMHO.

  39. Why SkS withdrew from the Bloggies

    Magma, can the lazy get a live link for that quote?

  40. Why SkS withdrew from the Bloggies

    Since part of the problem,as pointed out by several commenters,is that the voting is more a sign of zealousness,as opposed to popularity,maybe the Weblog Awards could get around that by restricting the voting to only one vote per person.Not a cure,but that would prevent 'ballot stuffing' so to speak.

  41. Why SkS withdrew from the Bloggies

    Some 'awards' are not worth the effort. As The Guardian quotes the Bloggies founder:

    But it seems that science blogs would rather complain about the results than try to submit nominations themselves, so I'm not very motivated. No point in eliminating sceptic blogs from the category when there's not much down the list to replace it with.

    Why play in a rigged game when the prize is worth so little?

  42. Why SkS withdrew from the Bloggies

    Not necessarily different, no.  As with the widespread "if by whiskey" arguments using "catastrophic," the term "alarmism" can mean many things to many people.  To me, the current rate of drop in ocean pH is alarming, because acidification events damage sealife, disrupt ecology, and threaten the food supply, and the current rate of drop is likely unprecedented (Honisch et al. 2012).  It wouldn't be so alarming if I knew that the world was preparing to do something about it.  Instead, the world is being successfully influenced by fake skeptic blogs that claim it's no big deal.

    If you look carefully (actually a brief glance will do) at the history of CA, WUWT, Jo Nova, et al., you'll see that advancement of the science is not at all a concern.  These sites attack climate science. They do not work with scientists to advance the science, and they never have.  The rhetoric on these sites screams, "climate science is a hoax! Doubt! Doubt! Doubt!"  I would not characterize them as "pseudoscience."  I understand what Feynman is saying re sociology and psychology.  They are necessarily "soft" because humans are extraordinarily complex, and we have to read ourselves from within our current historical moment, the bias toward which is quite difficult to overcome.  Feynman doesn't account for the more recent advances in cognitive science and the converging sciences of psychology and biochemistry.  

    Climate science is, in general, not "soft" in that way.  The physical processes involved are studied in the usual scientific way, and that study is thoroughly grounded in physics, chemistry, and biology.  Climate modeling has a "soft" aspect simply because the human response is involved.  The variable with the greatest range of movement in all climate modeling regimes is the human response.

  43. Why SkS withdrew from the Bloggies

    Okay, thank you DSL #45. Yes basically I had the computer models in mind. Anyway I'm talking about Climate alarmism as pseudoscience, not about Climate Change, and Climatology as a whole. Please, note these are very different things, isn't it?.

  44. Why SkS withdrew from the Bloggies

    Ecletikus, you say: "they are no susceptiuble of falsability, and fail to fulfill the Scientific Method."  Precisely what are you talking about?  The fundamental theory has been tested in lab, inferred from satellite (MODIS), and directly measured from surface (e.g. Puckrin et al. 2004).  Are you on just about modeling?  If so, say so.  Blanket coverage usually gets a body into trouble.  If it iss about modeling, perhaps you could list your specific complaints on the appropriate thread.

  45. Why SkS withdrew from the Bloggies

    Climate4All: "For Gods sake people, engage one another."


    I thought you said you weren't interested in discussing the science.

  46. Why SkS withdrew from the Bloggies
    Hi all!
     
    Just a note about pseudoscience. The term itself is a modern term who started on XX century. The pejorative connotation is still more modern, coming from probably when it was linked with homeopathy, astrology and so on...
     
    For example, Feynman includes Social Science and Economy on pseudosciences (but without the pejorative tone): http://www.youtube.com/watch?v=HtMX_0jDsrw
     
    I am almost sure that Feynman would do the same with Climate Alarmism today (again without the pejorative tone), because in many senses, suffers of identical failures than Economy, Sociology... they are no susceptiuble of falsability, and fail to fulfill the Scientific Method. 
     
    To say that blogs as WUWT, and many other in the same wave are pseudoscience crap, says nothing about these blogs and a lot about the people claiming that. IMHO you better should ask yourself why people read skeptics blogs more than others, and where are the differences.  
     
    Best Regards.
  47. Living in Denial in Canada

    Ray @9, so what?  Australia can afford its $23 AU per tonne carbon price applied to the largest poluters only.  California, presumably, can afford its $13 AU per tonne carbon price applied to a wider range of entities.  The fact that the two carbon prices apply to different ranges of entities means a simple comparison of price does not tell you the relative costs of the schemes, but that is beside the point.

    The key point is that both Australia and California, by implimenting a carbon price, will find their economies adapting to a low carbon economy.  That means both will be well placed economically when global agreements on carbon pricing are eventually implemented, at which time their carbon prices will be brought into line with each other, either by design or by trading between different carbon markets.

    In contrast, nations and states with no carbon price will either come into a global carbon pricing system with high emissions because they have not already started adapting; and hence at high cost - or worse, based on the fear of that possibility will hold up the implementation of a global scheme to the disadvantage of us all.

    Words like pseudoscience or anti-science were never used about Copernicus, Gallileo or Newton becasue the term "scientist" was not even coined until the 19th century.

    "Skepticism" is the Apple-pie of denialism. Who could possibly be against "scepticism"? But I think true scepticism is the recognition of the provisional nature of scientific knowledge, and that it will change is response to observations. What do you say to someone who refuses to assimilate and understand evidence, who continually shifts the goalposts and who regurgitates arguments already refuted?

  50. Living in Denial in Canada

    Tom Curtis@5, I won't debate what might or might not happen by 2050 regarding the legal status of non-permitted emissions nor whether criminal penalties ahould be added to civil penalties, etc. It's off-topic. I won't discuss the details of possible 2050 visions here unless those details are directly relevant to assessing whether the existence of a widely shared vision of the future, now only 37 years away, might be useful in reducing implicatory denial. The question I raised is what to do about implicatory denial, i.e., the large middle (in many cases, the majority) of people distributed from active denialists to climate researchers and activists. The middle believes the science, believes AGW is a serious problem, believes something should be done about, BUT continues BAU and doesn't demand appropriate action from government and business. My question is why are they in the implicatory denial state and what might suffice to make some of their behaviors conform to their beliefs.

    Ray@6, I have a good idea of the distribution of wealth and life styles around the globe and can envision a quite different world in 2050, for example, a world in which almost nobody cooks with wood or animal dung.

    In Calhoun's 1968 lecture at the AAAS meeting in Dallas, Texas, a simple model was presented involving five historical revolutions and two future revolutions. The historical revolutions were identified as the traditional-sapient revolution (about 33710 BC), the living-agricultural revolution (about 8157 BC), the authoritarian-religious revolution (about 519 BC), the holistic-artistic revolution (about 1391 AD), and the scientific-exploitive revolution (about 1868 AD). The future revolutions were identified as the communication-electronic revolution (about 1988 AD) and the compassionate-systems revolution (about 2018 AD). It seems to me that Calhoun was reasonably accurate regarding the communication-electronic revolution, a "new perspective of life as an information exchange network and ... the development of theories and electronic technologies for the transfer and condensing of information as the means for enhanced coping," which is particularly surprising to me given the simplicity of his model. If his prediction regarding the compassionate-systems revolution is just as accurate, which I hope it is, then the world will be very different two decades from now.
