Comments 63501 to 63550:

  1. Medieval Warm Period was warmer
    JMurphy: You need me to supply dates? From the multitude of posts you have through out this forum, one would have thought you had dates of this period firmly established. The dates that seem to be well established are 850-1300AD +-(50 years). The proxy data does not have enough resolution to isolate it to a precise year. As far as temps being warmer than current, the resolution of the proxy data used in MWP reconstructions is NOT defined enough to state with certainty that it warmer presently than at some period during the MWP. And in fact, that isn't even an issue. The isue at hand is WHY it was as warm during the MWP as it was. Current solar data is very upfront in showing that the cause of warmth was not solar/TSI related. Volcanism was not a contributor as the time scale of temperature disruption from volcanoes is not long enough to be a variable, and the resolution of the proxy data would not show it anyways.
  2. Medieval Warm Period was warmer
    Camburn @103, Neukom et al present a reconstruction of summer temperatures for Southern South America only. Last time I looked, the year was not 3 months long, nor the Southern Hemisphere confined to Southern South America. Consequently it is impossible to legitimately draw the conclusion you make from the data you link. More importantly, Neukom et al show a cool period from 950 to 1200 AD, coinciding with the warmest period of the NH MWP. The show a warm period from 1200 to 1400, after which temperatures decline sharply to the coldest in the record, two centuries before the Maunder Minimum and the end of the NH MWP. In other words, averaging this temperature reconstruction with NH temperature reconstructions would smooth out the record, lowering reconstructed temperatures at the beginning and end of the MWP, while raising them in the period shown as the coolest part of the MWP in most NH reconstructions. Ignoring the details of the reconstruction as you have done is entirely uncalled for, and is contrary to good scientific practice. I note that your 101 consists of a serious of dubious claims made with no supporting evidence. If you want to debate by sloganeering, as your 101 suggests you want to, then you have nothing interesting to contribute to the debate and do not warrant response.
  3. Global Extinction: Gradual Doom as Bad as Abrupt
    I have to agree that even if we can turn the denialist politicians and business leaders around it's going to be a helluva battle to save the planet as we will be ankle-tapped by the concurrent arrival of the loss of cheap energy, population overgrowth, diminishing resources and erratic weather limiting food production. Google the essay "I, pencil" for a mind-reset on just how fragile our civilization is. If it's that complicated making something as simple as a pencil, there's no way that hard drives are going to last long even assuming we can find a substitute for the lubricant needed for the bottom bearing on a hydro generation turbine. We will be able to make beer mugs, a bit of clay and fire will do that, but beer needs malt which needs barley which might be a struggle with the repeated storms and droughts.

    PLbrunson--because studies and data have no effect on some people. This site is dedicated to the communication of climate science to non-scientists, and sometimes that requires revealing for what they are those people, projects, and organizations who are significantly responsible for keeping people ignorant of the actual science.
  5. DenialGate Highlights Heartland's Selective NIPCC Science
    Please keep repeating this: "To sum up, IPCC mainstream climate science is about taking an accurate, comprehensive view of the entire body of climate science evidence, which inevitably leads to the conclusion that humans are causing dangerously rapid global warming." Note this phrase:"taking an accurate, comprehensive view of the entire body of climate science evidence,". Spending time understanding what the accurate, comprehensive view of the entire body of evidence is more productive than discussing NIPCC machinations.
  6. A mishmash of Monckton misrepresentation
    Philippe Chantreau @ 70 Thanks for the link! Unfortunately it is broken, but I did manage to find it anyway. I have to agree with you: "Damning" indeed. Will it stop him, or will his desperate need to be the centre of attention force him to carry on regardless of the facts? No prizes for guessing which!
  7. Medieval Warm Period was warmer
    Camburn, have you actually stated when the MWP occurred, i.e. what dates were globally warmer than current temperatures ?
  8. Global Sea Level Rise: Pothole To Speed Bump?
    It will be interesting to see how much sea level rises over the next few months as conditions in the tropical Pacific move toward neutral. There seems to be greater volatility in the sea level response, but it may be temporary.
  9. Fritz Vahrenholt - Duped on Climate Change
    I presume elsa would also decry those who had to come up with dark matter and dark energy to iron-out discrepancies in the standard model of cosmology. Those dastardly scientists, eh ? They can only solve this problem by coming up with stuff that is very difficult to falsify, let alone prove ! In fact, I would go so far as to state : The facts did not fit the theory, as the expansion of the universe accelerated and discrepancies were found with regards to the mass of large astronomical objects. So the big-bang group has then to add other factors to make it work. But such a theory is no longer testable, it will always be right.

    Hijacking amendment – yes. It is a good policy to keep the discussion relevant, besides it is already the unwritten policy. Written policy and practiced policy should match.
  12. Medieval Warm Period was warmer
    As far as being global, it does certainly seem that the MWP was global. Southern South America temp proxy record. This study is done on Southern SA temperatures, the results indicate that the Southern South America region recognizes proxy data that supports temperatures within the expected anamoly of the NH MWP R. Neukom et al
  13. A mishmash of Monckton misrepresentation
    The Monckton response to Abraham (or, more accurately, the Monckton response to what Monckton creates as being from Abraham) also contains the following fallacy : "Santer who rewrote the IPCC’s 1995 report, on his own, so as to change its principal finding by 180 degrees" Completely made-up and shown to be wrong. The only 'difficulty' is deciding whether you believe the people actually involved, or those who believe in conspiracies. But I don't understand this Monckton claim : "What evidence do you have that I cited Caillon et al. (2003) in my talk?" Listening to the Abraham presentation again (especially slide 62), I couldn't hear or see any such claim, and certainly couldn't hear/see anything along the lines of what Monckton claims is a "papraphrase" of Abraham : "And what he says, ... temperatures always change first and CO2 follows, and he cites the paper which I’ve got the citation listed here, [Caillon et al., 2003], which deals with the timing of CO2 and Antarctic temperatures." Either that is a Monckton version of paraphrasing (i.e. not an actual paraphrase), or it is something that has been removed from the presentation.

    Koch Brothers? not so much, in fact nothing for climate in at least ten years if ever according to this update at Desmogblog.
    [Update: Apparently even the Koch brothers think the Heartland Institute's climate denial program is too toxic to fund. On Wednesday, Koch confirmed that it did not cut a check for the $200K mentioned in the strategy memo after all. A statement released on KochFacts.com and the charleskochfoundationfacts.org states that "…the Charles Koch Foundation provided $25,000 to the Heartland Institute in 2011 for research in healthcare, not climate change, and this was the first and only donation the Foundation made to the institute in more than a decade. The Foundation has made no further commitments of funding to Heartland.”]
  15. A mishmash of Monckton misrepresentation
    Look on the bright side, when Monckton makes high profile erroneous statements, it gives an opportunity to give high profile correction. After all if you can’t see the fox who is eating your chickens you can’t catch him. In some ways it’s better to have wrong information out in open where it can be challenged.
  16. DenialGate Highlights Heartland's Selective NIPCC Science
    @33-muoncounter It's hard to say what influences people's beliefs about the world- most seem to reduce explanations to something that makes sense from their own experience- re the seasons -their everyday experience is that if you move closer to a heat source (the sun) you get warmer and if you move farther away you get colder. I have an engineer friend who thought the seasons were caused by the 'precession of the equinoxes" until I asked him to think about that. Living in the relatively far north, I associated warm temperatures with long days and short nights, and it took me some time to realize that this didn't work at the equator. It may be that this kind of approach plays into the denier meme-what's a few degrees between friends, 390ppm-that's hardly any, how can that affect climate, etc. In my opinion, that kind of 'common sense' inertia is one of the major things the scientists have to contend with.
  17. Fritz Vahrenholt - Duped on Climate Change
    I don't think that's correct elsa. The climate isn't so complex at the level which is relevant to global warming (it's fundamentally about energy flow into and out of the earth system and its contribution, together with some understanding of how this is manifest at the earth's surface where we all reside). One does need to be careful switching back and forth between philosophy of science descriptions (e.g. in the (vi)-point schematic you reproduced in your post!) and the real world. However the fundamental theory of AGW arising from 19th century science (that increased atmospheric [CO2] results in a warming contribution) has been tested virtually to destruction. Simply put it's completely compatible with observations. We've gone through steps (i) to (iv), and everything is holding up - the essential theory hasn't needed to be refined very much, 'though it would be silly not to continue to incorporate new knowledge into our attribution of component contributors to surface temperature changes. A more general theory is that the actual surface warming is the result of all of the external and internal contributions to surface temperature change, and that at equilibrium, a persisitent temperature change must result from an enhanced external forcing. Again the observations are entirely compatible with that. I don't agree with your statement about "AGW for the period 1940-1970". The change in greenhouse forcing in the middle part of the last century was small. So [CO2] was 299 ppm in 1900, and hadn't even reached 320 ppm by 1960. It's the massive post-war industrialization that took off in the mid 1960's and has seen [CO2] levels race up towards 400 ppm that has resulted in the large late 20th century warming. So the lack of surface warming in the period 1940-1970 isn't surprising when one considers all of the contributions to warming including the (then) quite small greenhouse forcing. The theory of greenhouse warming is eminently testable and falsifiable. We can determine the earth surface temperature projected from quantitation of natural attributions to temperature change and see that these cannot result in warming from the mid 20th century til now. All of the sub-components of the theory are testable and falsifiable (the absorption characteristics of greenhouse gases; top of the atmosphere radiative changes; predictions of atmopsheric water vapour concentrations; tropopause height variations and stratospheric temperature changes and so on)...
  18. Medieval Warm Period was warmer
    Crowly 2010 is using old TSI reconstructions that have been updated. Refer to my post from Lief.org slide 7. Hence, this paper has little bearing on the reason that the MWP was a warm period. It is obvious that TSI was/is NOT a factor in the MWP temperatures. Volcanoes are short lived and unless we had had a super erruption, would not be detectable in the resolution of the proxy data presented for the temps of the MWP. Once again, based on the current science published, why were temperatures higher in the MWP?

    Fritz Vahrenholt - Duped on Climate Change
    Elsa, the experiments/observations on which AGW theory are based are repeatable and could be run over and over again. As I pointed out the theory of AGW predates global observations. "This is what happens to the AGW theory for the period 1940 to 1970s. The facts do not fit the theory as the world cools in the face of rising CO2." This is simply incorrect, and is based on your ignorance of what the theory actually predicts and of the historical development of the theory. CO2 radiative forcing is only one of the forcings that govern long term climate, as it says, for instance in the IPCC WG1 report. Does AGW theory say that temperatures cannot fall while CO2 levels rise? No, it doesn't. "But such a theory is no longer testable, it will always be right. " That is also nonsense. AGW theory makes falsifiable projections.
  21. Fritz Vahrenholt - Duped on Climate Change
    60, elsa, Sort of like having a theory of classical mechanics, except the speed of light doesn't fit, so someone devises some crazy Theory of Relativity just to make the obviously flawed, broken and useless model of classical mechanics fit the observations (rather than doing the smart thing, and just plain starting over)? And then other people develop more ideas, like quarks and string theory and everything else? You're right, it's all completely crazy. Why keep expanding on what you know and further refining your understanding of a complex system, when you can instead oversimplify things and throw out everything you do know because the details don't line up perfectly the first time? Why base a theory of climate on well-known, well-understand, and proven things like atmospheric chemistry and physics, and then try to understand the other factors that influence and complicate those physics, when you can instead simply invoke the powers of the Flying Spaghetti Monster?

  23. Global Extinction: Gradual Doom as Bad as Abrupt
    In the EPA's worst case scenario of co2 emissions, co2 levels by 2100 are projected to be about 1000ppm. .1% if my conversions are right. By the end of Permian extinction, co2 levels reached 12%, and due to desertification and ocean anoxification, o2 levels dropped to almost 15%.
  24. Fritz Vahrenholt - Duped on Climate Change
    Chris, you say that the way we should do things is: (i) perform experiments/observations (ii) formulate a theory (iii) devise and perform experiments/observations to test the theory (iv) compare results with predictions... (v) refine or abandon theory... (vi) repeat steps (iii-(vi) I would mostly agree with you if we were dealing with a simple situation, eg just the force of gravity, where we could run an experiment over and over again. Unfortunately with climate we are dealing with complex phenomena with the added difficulty that we cannot run the experiment over and over again. That is why we need a starting point which is given to us by something other than measurements we have already taken, otherwise we can "refine" our theory as you put it but all we are doing is making the numbers work so the theory cannot be wrong. This is what happens to the AGW theory for the period 1940 to 1970s. The facts do not fit the theory as the world cools in the face of rising CO2. So the AGW group has then to add other factors to make it work. But such a theory is no longer testable, it will always be right.
  25. Fritz Vahrenholt - Duped on Climate Change
    Tonydunc, my apologies that I have not had time to get back to you sooner. The question you ask is, I think, do I consider the alternative explanations of global warming to be as unscientific as the general view expressed here. The answer is yes. The models that apparently explain warming via sunspots etc are equally poor and are not scientific in any way.

  28. A mishmash of Monckton misrepresentation
    84 - JMurphy Thanks for the clarification. Only I had notice, in the deniosphere, that if any individual or organisation makes one statement that isn't 100% true for all eternity, they - and any statement they make or results they produce - can be considered, not only totally discredited, but eligible for prosecution for fraud... I am, of course, thinking of the IPCC, Mann etc. Such a situation couldn't be applied to TVMOB et al. of course. who can make as many errors as they like while still maintaining full credibility...
  29. A mishmash of Monckton misrepresentation
    les, you should be aware by now (if you have been listening carefully to the so-called skeptics, and Monckton) that Hansen and Gore are in on the big conspiracy, so that Hansen produces the 'goods' (the 'hansenised' data, as you will have read it from many of those in denial) which allow Gore to take advantage by buying properties virtually in the oceans (give or take a kilometre or two) and setting-up companies that can make a killing in the carbon-trading market - thereby increasing his wealth from billions to squiilions. (Just in case any Monckton fans are reading : I am joking)
  30. A mishmash of Monckton misrepresentation
    From the same document of 82-logicman "When Hansen’s political ally and financial beneficiary Al Gore..." Over and above Hansen being in receipt of government funding and, at some point, Al being in a completely different part of government... is there any evidence for that?
  31. Breaking News…The Earth Is Warming…Still!
    Ken Lambert - If the oceans are not warm enough for the TOA imbalance to be canceled, then there is disequilibrium, and future warming in the pipeline. As long as there is a TOA imbalance, and the thermal inertial of the climate has not caught up to it, there is still warming that will occur. I have to consider your post to be semantic gaming of this point.
  32. A mishmash of Monckton misrepresentation
    JMurphy #80 The "feet from the ocean" quote is from a document published by a little known organisation called the Heartland Institute. Perhaps some of our readers have heard of them? "In 2005, the year [Al Gore] said sea level would imminently rise by 20 feet, he bought a $4 million condo in the St. Regis tower, San Francisco--just feet from the ocean at Fisherman’s Wharf." Source: Great Is Truth, and Mighty Above All Things, Lord Christopher Monckton – March 12, 2009 Anyone who cares to look at a map will see for themselves that the building in question is at least half a kilometer from the ocean.

    The Year After McLean - A Review of 2011 Global Temperatures
    Ken Lambert: "So ENSO is not the explanation for the last decade stasis in surface temperatures." This is rather silly pedandtry, ENSO is AN explanation for the "stasis", not necessarily THE explanation. I note you have performed the same pedantry in a response to scaddenup. Such behaviour does you no credit whatsoever, and I suggest you avoid it in future. Foster and Rahmsdorff's model uses ENSO, solar and aerosol forcings to explain the variations. If you want to show that ENSO is not responsible, you need to show that changes in solar and aerosol forcings that can explan the "stasis" of the last decade, whilst still being consistent with the observations since the start of the analysis? If you can demonstrate that, then your assertion might have some value, the ball is in your court. However, the major movement in the goalposts is that you said that "likely answer could be an unknown ocean cycle". I pointed out that this would be in contravention of Ocamm's razon becase ENSO already does a good job (as it happens in conjunction with solar and aerosol forcing if you want to be pedantic). Nothing you have written contradicts that.
  34. The Year After McLean - A Review of 2011 Global Temperatures
    scaddenup #55 "Foster and Rahmsdorff however show quantitatively that combination of ENSO, Solar and aerosol are sufficient to explain the observations." Well that is 3 reasons not just ENSO.
  35. The Year After McLean - A Review of 2011 Global Temperatures
    scaddenp #56 Do you mean El Nino or La Nina have dominated since 2005?
  36. Breaking News…The Earth Is Warming…Still!
    PN #58 "You say that you are considering the warming imbalance from all effects. But is the modelled 0.9 to 1 W/m^2 that you mentioned based retrospectively on the true (estimated) forcings or was it produced by the models as an ensemble average?" A good question. Fig 2.4 of AR4 plus climate responses is the answer. Ref Trenberth 2009 - "Tracking the Earth's Energy...." Probably a bit of both your options.
  37. Breaking News…The Earth Is Warming…Still!
    KR "As long as there is an energy imbalance at the TOA, as long as the oceans in particular are in thermal disequilibrium, there is "warming in the pipeline", or as I prefer to term it, unrealized warming." In thermal disequilibrium with what? The ocean heat content is a finite quantity at any point in time. Temperature might be in disequilibrium - but that is probably always the case.

    Having done this unrewarding job myself once, I value the work of moderators here. It's subjective, yes, but they do it very well. As someone said above, if people don't bite, there's no hijacking. If comments don't hurt other moderation rules, I think the proper think to do would be just warning people of the hijacking, so that they become aware of it. No extra rule needed, IMO.
  39. A mishmash of Monckton misrepresentation
    Adam @ 57 says: "I've had a look at Huang's 2008 paper, and I agree with you that their 1997 paper was not the best choice of study to include as evidence of a MWP. Although I do not believe that there was anything nefarious about Monckton including it in his talk. It was probably just an honest mistake. And might I once again point out that it is only one paper. Monckton showed graphs from eight other studies showing MWP temps were the same/higher than today. You can't just pick out one single study from his talk, and then just act like everything he said was wrong..." "Probably just an honest mistake". Really Adam? Do you consider Monckton's insinuation that Sir Richard Houghton supports telling lies and Monckton's made up false quotation he ascribes to Houghton are also "honest mistakes". You seem to have an elastic concept of "honest"! I can't see how Monckton's extreme misrepresentation of Huang's borehole data can be an "honest mistake" when he's gone to the trouble of preparing or hunting down a made-up graph that isn't Huang's at all. Monckton's (misrepresentation of) Huang's borehole data is just one of 9 examples in that slide. But as Abraham shows Monckton's misrepresentions on that slide is more widespread. We could choose another example: e.g. Monckton cites Keigwin (1996). This data set refers specifically to a location in the Sargasso sea. If one was to address this particular data set scientifically, one would likely conclude that it was consistent with a growing consensus that the temperature variations during MWP (and to a lesser extent) during the LIA, were significantly related to ocean current and wind transport regime changes that changed the distribution of global heat, with a large contribution involving “Gulf Stream” heat transport to the high Northern latitudes. It’s not surprising that temperatures in the Sargasso sea are sensitive to these. So Keigwin and Pickart (1999) have shown that if one samples historical temperatures from cored proxies in the Laurentian Fan area to the NW of the Bermuda Rise, Sargasso Sea data, that sea surface temperatures were apparently much colder during the MWP compared to the LIA, and the temperatures of the Bermuda Rise-Laurentian Fan vary in “antiphase” as current regimes change. In other words if Monckton were to have selected Keigwin and Pickart (1999) rather than Keigwin (1996) he would have come to the opposite conclusion. Monckton has "cherry picked" one piece of Keigwin's work that seems to support his agenda. Another "honest mistake" Adam? It's easy to show (simply by doing the reading of the scientific literature that any honest scientist does in putting his work in context) that in addition to misreresenting the work of Huang, on that slide, and Kiegwin, Monckton also misrepresents the work of (at least) Schonwiese, Esper and Schweingruber since the analyses of all of these scientists indicates that in their study context late 20th century and contemporary temperatures are warmer than during the MWP.
    Moderator Response: [Dikran Marsupial] The comments policy forbids accusations of dishonesty:

    No accusations of deception. Any accusations of deception, fraud, dishonesty or corruption will be deleted. This applies to both sides. Stick to the science. You may criticise a person's methods but not their motives.

    In order not to stray into dangerous waters, please everybody stick to the question of whether the science is correct or not, and avoid the issue of the motivation altogether.

    I endorse moderation along the lines suggested above. There will be grey areas, and I am happy for the mods to use their discretion. I must say though that I am attracted to AT's suggestion -- that those who post controversial claims should be invited to document or expressly retract/modify their claim, and be in moderation until such time as they do. In addition, they should be required to respond expressly to actual refutation material posted here. A failure to meet that standard would see the post deleted. A special thread could be created for the purpose. That would cut out the endless reiteration of long debunked talking points.

  43. A mishmash of Monckton misrepresentation
    It's obvious that Monckton's claim about the St Regis Tower in San Fancisco being "just feet from the ocean at Fisherman's wharf" is blatently false as far as any normal person (i.e. the majority of rational human beings) would understand it. However, judging by the rest of Monckton's attempted justifications highlighted here by others, he will undoubtedly believe he is correct (and his followers will accept his justifications implicitly) because he said "feet", which, in his mind, encapsulates every number from two to the largest number you can think of. He plays with words and uses them so that he can create his own reality and never have to admit being wrong. No wonder Adam likes Poptech too - he has the same modus operandi.
  44. A mishmash of Monckton misrepresentation
    Adam, I went through every one of Moncton's points when he came out with the rebuttal. I do remember three or four specific things that seemed to me to have been clearly valid points by Moncton. It was a long time ago, if you wants to pay me for my time, I would be happy to go through the while thing and find those places. the whole opening first pages of his response is rather self serving rubbish (meant in the English sense of the word).It is patently arrogant and obnoxious, and strangely silly, almost infantile in places. Of course that in itself is not reason to dismiss it. Can you tell me you actually read those first few pages and did not think it pretentious nonsense? Oh What the heck I will do it now for free. And I am no scientist, so it is pretty sad that someone with no rigorous background can so easily see through his supposedly brilliant rhetoric. the first 25 are meaningless snipping. 26. Moncton quotes Abraham as saying that " And if you listen to what he said, you would come to the conclusion that the following things are true" then he lists ice melt, world not warming,scientists are lying, etc. 27. The VERY NEXT point he CHANGES that "What evidence do you have for your assertion that I SAID, “The world’s not warming”. That is so obvious any intelligent person ( and certainly any judge would see are two different things. 28. He goes on to point out that he acknowledged warming in the 20th century. Abraham never claimed that Moncton denied that. 29. he then says that since 2001 has been a cooling trend. Which of course is a lie. 30-33 is the exact same thing only with sea level. Nowhere does Abraham state that Moncton said there has been no sea level rise since 1990 34-37 is exactly the same regarding sea ice melt. Of course Moncton does admit to talking about arctic recovery, for which he is of course absolutely wrong. 38-39 is similar about Polar bears being threatened. As far as I know Moncton is distorting when he says Polar bear populations have increased "very substantially" since the middle of the 20th century. I think there was some recovery due to lack of hunting. But recent studies show a decline, but this is a pretty sketchy issue on both sides of the argument in my view, and not really pertinent to determining ACC. SO another lie by Moncton. 40-42 is ocean acidification. And that one s a hoot, as he invents a series of fanciful myths about the changing nature of climate change by duplicitous climate extremists. But his argument, in my view totally supports Abrahams contention that one would get the impression that there is no such thing as ocean acidification. Is Moncton stupid or was he just pretty sure no one except an idiot (like me) would actually bother reading that far. 43-49. is about scientists lying. Now here I do not know enough to pass judgement on the ethics of statistical use. though I think it rather laughable that Moncton is schooling Abraham about it. Still as an entertainer with an interest in climate change it is celar that the IPCC was not :lying" when they conclude that global temp has been increasing faster in late 20th-eary 21st century than from the early and mid 20th century. He would have a point for the past 10-13 years, but even that is disputable if one factors in mitigating issues, such as solar radiation and aerosols, etc. 47-49 are one of the places where I thought he did have a point. Atlantic hurricane strength. But this is a case not of lying but of cherry picking. Again here is an issue that I do not think is germane to the question of climate change as there is no real consensus among experts on specific effects of storms at least not in the current time frame. 50. Moncton conflates "Where I said conspiracy" with "one would come to the conclusion" 51-61 is an amazing piece of rhetoric that is almost pure garbage 52. Gore never said there was an imminent threat of a 20 feet rise in sea levels because of ice sheet melting. Now having seen the movie, i was not thrilled that he did not say it would take many hundreds of years. and there were probably some that took it as being in the relatively near future 53-54. Moncton makes the nearly insane assertion that sea level rise from ice sheets in the coming century would be comparable to 20th century melting of the ice sheet. 55. Irrelevant nonsense. 56 Greenland ice sheet melting. flat out distortion of the science and a use of the word millennia, which, if we want to be picky means at LEAST 2 thousand years , and almost certainly flat out wrong. If Global temps go to a 3°C+ anomaly and stay there, I am pretty confident that any physicist would agree it will not take thousands of years for Greenland to have a nice luke-warm lake in it's center. 57 pretty much the same thing as 56 and untrue. 58 just blatantly untrue. IPCC is very clear that melting of ice sheets is a very difficult thing to determine with rising temps. 59. Distorting the legal ruling on Al Gore's movie. Judge Basically said that Gore's movie could be interpreted to be in the near future and that it should be pointed out to students that complete melting would take a very long time. Quite reasonable on the judge's part. So this is basically a lie. 60. Strawman argument about Gore's buying shorefront property. 61. argument about lack of sea level rise in spite of accelerating ice melting. Moncton has no explanation or rebuttal to the cited reference, just asks a seemingly devastating rhetorical question. Pointless. the issue is more complicated. 62. temperature of last interglacial. Minor point subject to interpretation. But at least this was not an outright lie or distortion. Big victory for Moncton here! 63. Whining about scientists making unsubstantiated64 assertions in referenced citations? Who knows maybe there is some validity, but still rather meaningless. 64-65. Something about IPCC projections and and doubling of CO2 and committment to future climate change. Need someone else to answer that one. 66-77. About polar bears. Again I don't see this as being of particular relevance to determining the reality of ACC. Mostly ridiculous gobbledy gook that is rather lawyerly trying to establish reasonable doubt about Moncton's distortion. The fact is that he cited a paper by an expert on polar bears and only used the information that made it appear that ACC has nothing to do with polar bear survival. He totally ignores accepted views on polar bear evolution assuming they were the same as they are now during the last interglacial, and ignoring that species can be at the brink of extinction and survive to spread rapidly. So a major change in the arctic could very well be disastrous for polar bears But he might have a point here, who knows. his point that this was four polar bears that died from a storm is not unreasonable just one sided. Waste of time basically. Ok. I am up way past my bedtime. If you, Adam, or others want me to continue, let me know and I may be able to do so tomorrow. So far I agree with my hazy memory and the contentions of numerous commenters that this is mostly a gish gallop of the ridiculous, the sometimes plain wrong, and occasionally blatant lies from Moncton.
  45. Book review of Michael Mann's The Hockey Stick and the Climate Wars
    Well, having read it. First and foremost can I offer a health warning. If you've ever - and most people have - suffered from some level of bullying or victimisation at work; this'll bring back those memories, pumped up on steroids. By the end of the 2nd from last chapter I was feeling deeply angry. Indeed, although I appreciate the comments policy of SkS - I was feeling like there should be a site where one could sink to the same level towards deniers as they have towards climate science... My other, overall, impression was "wow! Did that really happen so long ago?!?" - there are so many 'arguments' which continue to float around the deniosphere, which are just so old, out of date and discredited. It really makes you wonder what they spend their Heartland Institute money on. Finally, I guess I agree with Liam23 that the PC story remains opaque. I though it was well explained but, as 63 Brandon so clearly shows, it's possible to miss-read. Mann actually says that the tree ring data could dominate the analysis if he hadn't actually done the PC analysis correctly... which he does, which he does explain but, clearly, it's still opaque to many people. And what a shame that people miss the point that the same analysis has been reviewed, repeated and supplemented with other data so often that, in full context, the original hockey-stick analysis was as solid as it could be. all in all, a good read.
  46. 2012 SkS Weekly Digest #7
    Again, IMHO, the hijack/troll issues seems to point to a "dungeon" thread for comments... except it doesn't seem easy to move comments between posts. I was on one BB somewhere where the admins had a hack so that selected posters could only post in the dungeon (for a period, anyway).

    My wife LOLed at the beaker part of the cartoon, which I take to mean that's how she see me.
  49. A mishmash of Monckton misrepresentation
    Yes, when you engage Monckton you must understand you are engaging in a political agenda. He has made climate change the dominate part of his political platform so it’s extremely important to counter the destructive influence his bogus science and misinformation is having on the understanding of the scientific facts behind global warming and action to limit its effects.
  50. Search For 'Missing Heat' Confirms More Global Warming 'In The Pipeline'
    MA Rodger@ 16 The recent GRACE paper suggests a slightly lower contribution of land-based ice melt to sea level rise, which, if confirmed ,indicates greater thermal expansion than previously supposed. There's much work yet to be done on this, I wouldn't hang my hat on it.
