dana1981 at 03:41 AM on 22 September 2012PBS False Balance Hour - What's Up With That?
Yes that explains why the segment was more about 'why are you a skeptic?' than 'what do you think is wrong with the science?'. It's rather absurd that PBS excludes their science correspondent from climate science stories. -
Doug Bostrom at 03:29 AM on 22 September 2012PBS False Balance Hour - What's Up With That?
Intriguing detail. Bud Ward of the Yale Climate Media Forum wonders why regular News Hour science correspondents didn't handle the Watts segment:Why not use veteran science correspondent Miles O’Brien, who NewsHour brought in to cover complex science issues after he and the science staff had been let go by CNN? Climate change is an issue on which O’Brien has done substantial earlier coverage, and it’s a subject he says he is eager to continue reporting on. There’s an answer to that question, actually. O’Brien said in a phone interview that he is a freelancer with a contract to do 15 science stories a year for NewsHour … specifically excluding climate science.
From this article: A PBS ‘NewsHour’ Blog Post and Broadcast Provoke Viewers’ Ire That suggests News Hour has cast climate science completely into the political affairs bucket, a sad mistake because dragging politics into science promotes exactly the sort of cloudy thinking we saw from Watts. Was the segment about politics, or climate science? Impossible to tell. -

Dikran, there is no PaCo2 to PaO2 imbalance. It's rather the opposite. The article by Dr Zubieta-Calleja I cited above has the complete discussion. BTW, the address was damaged, this is the real link: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3068777/?tool=pmcentrez The tutorial on altitude sickness I cited earlier is also very clear. Hypercapnia is not involved. Hypoxia is the primary cause of hyperventilation that persists to and beyond alkalosis. AH1 has no clue what he's talking about, he really should be ignored. -

Here’s yet another article hot off the press about the topic du jour. Does the expanding Antarctic sea ice disprove global warming? by Eric Berger, SciGuy Blog, Houston Chronicle, Sep 21, 2012 Berger’s opening sentence: “Ice is a hot topic in the climate science community right now so let’s talk about it.” Berger’s concluding statement: “The bottom line is that scientists generally have predicted that the Antarctic sea ice will not begin substantially melting until the second half of this century.” Berger’s blog post was created in response to the recent pious pontifications about polar ice by non-scientists James Taylor and Steve Goddard. -

Antarctica is gaining ice
John Hartz - Watts (at the hometown of denial) has already commented on this paper, dismissing it with "Oh wait, it's modeling, never mind." Golledge et al 2012 actually looks to be a very interesting paper - considering how fast moving peripheral glaciers in Antarctica may respond to warming oceans, with the potential to drawdown ice over very large areas. Essentially, at how speeding up these fast glaciers may "unplug" the ice stores over significant portions of Antarctica, allowing it to drain into the oceans. -

I too, occasionally 'fall off the wagon' of polite discourse and revert to Advanced Trolliana. Dale, you seem to have at least begun to listen to, and analyze, the real conclusions and findings of the past 50+ years of climate research. I hope that you continue to add *positively* to the discussion, and perhaps your postings on WUWT will be eventually moderated there, due to your coming over to the Light Side..;) If you've not already done so, I *highly* recommend Spencer Weart's book, "The Discovery Of Global Warming." truly a seminal work in the lexicon of those who want to learn of the history. -

Dikran Marsupial at 19:17 PM on 21 September 2012It's not bad
AHuntington1 wrote: "Dikran Marsupial, but adaptation to high altitudes does provide a perfect illustration of higher internal Co2 to O2 ratios." You are missing the point. How do you know that the effect is due to the difference in CO2 to O2 ratio rather than to other changes in body chemistry due to lower atmospheric pressure and lower oxygen availability. How do you know that the same effect will also be seen at sea level pressure with the concentration of O2 to which we are evolutionarily adapted? Now I suspect that if this were the case, then competent scientists would have performed the experiment to find out (e.g. monitor glucose metabolism in a sealed environment in lab conditions where all other factors can be controlled). The fact that you can't supply a single study where this has been done suggests to me that the scientists who work on this don't suspect that mechanism has a significant effect. So please answer this question directly and unambiguously: Is there anyone other than yourself that is promoting this hypothesis, yes or no? -

one more thing AH1 (@313) is off by a factor of ten regarding harmful CO2 levels: "In summary, OSHA, NIOSH, and ACGIH occupational exposure standards are 0.5% CO2 (5,000 ppm) averaged over a 40 hour week, 0.3% (3,000 ppm) average for a short-term (15 minute) exposure [...], and 4% (40,000 ppm) as the maximum instantaneous limit considered immediately dangerous to life and health. All three of these exposure limit conditions must be satisfied, always and together." available here -

John @157 (and DB): Just want to point out, I said "last couple of months". February is not, the "last couple of months". In fact, it's 7 months ago. Also, I will refer people to a recent SkS thread where I admitted my previous prose was not constructive and that I recognised that and wanted to attempt to change.

Philippe Chantreau at 14:57 PM on 21 September 2012It's not bad
How weak of me to be suckered in to this again. For my defense, I have to say that AH1's stuff is really funny in a way. For the sake of the sincere reader examining this thread, here is some more: AH1 gives every indication that he searches the web with the purpose of finding every little bit that could be used to say "CO2 is good for us." In the course of doing so he finds stuff that he does not really understand and makes bold assertions that he later amends by trying to imply that he meant something different. We had this on post#250: "neither aerobic nor anaerobic bacteria can survive without Co2 highlights this fact." With a link to paper that does not exactly say what AH1 says it says. From the abstract: "the observation that relatively low concentrations of CO2 were adequate for satisfactory growth of certain anaerobes was of particular interest." Walker and Winslow showed as early as 1932 the ability of E.Coli to grow in the absence of CO2 on a medium more complex than the very basic one. That's obviously not the kind of depth where AH1 will go. Whatever. Then we get this: "High altitudes provide a real life example of a population that breathes a higher Co2 to O2 ratio", in the same post. When corrected on this, AH1 amended himself by saying that it was a "mis-type", and what he meant was that people living at high altitude have a higher "internal" CO2 to O2 ratio. I had to introduce the concepts of PaCO2 and PaO2, which are very familiar to those of us who really work with this and really save the lives of people in respiratory failure. He showed no evidence of that supposed imbalance. Instead he cites this article: http://jap.physiology.org/content/16/3/431 The article says nothing at all about PaCO2 to PaO2 ratio but only reinforces the well known higher ability of high altitude residents to transport and use oxygen: "The higher O2 consumption per kilogram of FFM, C, or S in the high-altitude resident seems to be one of the many mechanisms developed by the body in its process of adaptation to the low O2 tension." I will add that, from a purely physiological point of view, CO2 elimination should be easier at high altitude. The body processes are unchanged and the PaCO2 resulting from metabolism remains about the same, but the absolute pressure of CO2 in the ambient air is much lower at high altitude, thereby facilitating CO2 elimination in the lungs. The published litterature suggests that high altitude dwellers are in fact in a steady state normal acid-base balance adapted to the lower pressure of CO2, exactly as one should expect from regulatory mechanisms: http://www.ncbi.nlm.nih.gov/pmc/articles/P(1)MC3068777/ I note that this paper represents a change from the previous dominant idea, which was one of chronic alkalosis. I showed a study looking at Sherpas that found a slightly higher PaCO2 than other people. AH! AH1 jumped on it with the belief that it proved his point but he missed that part: "(1) respiratory alkalosis was a common finding both in Caucasians and Sherpas." He also seemed to have missed this part: "Apparently a more efficient adaptation to hypoxia allows Sherpas to limit alkalosis through a lower ventilatory drive and to maintain SaO2 at the same PaO2 by decreasing the [2,3-DPG]/[Hb] ratio." Sherpas limit alkalosis by a more efficient response to hypoxia but still experience it. I'll note that Sherpas seem to be unique in this ability; that points to a genetic difference that has not surfaced in other people living at high altitude like those in the Andes. The point is: there is no PaCO2 to PaO2 imbalance in high altitude dwellers. Alkalosis is the initial response and an incidental cause of the reaction to hypoxia. Balance is restored with aclimation. Alkalosis is seen in higher altitude excursions even in highly adapted dwellers. The alkalosis is brought by responses to hypoxia, not hypercapnia. AH1 tries to wiggle out of his gross error on altitude sickness by trying to imply that the sickness is due to alkalosis as an overreaction to hypercapnia and that is what would happen to people exposed to suddenly increased high levels of CO2 at normal pressure. Total nonsense. If one was suddenly exposed to high levels of CO2 at normal pressure, ventilation would increase in order to restore normal PaCO2, then would stabilize as that goal would be reached and alkalosis would not develop. In altitude sickness, hyperventilation persists despite alkalosis because of hypoxemia, leading to further alkalosis. The vascular changes associated with low Co2 and low O2 are currently believed to be the most likley causes of vessel permeability leading to pulmonary edema and cerebral edema. AH1 made an argument about people's death rates at high altitude. I took the bait and looked at life expectancy, which of course did not support his argument. Then he went on to remind us of the distinction in terms and listed all sorts of factors that are more likely to affect mortality rates than life expectancy. Right. Makes sense. It is difficult to devise a good metric for population health. Despite controversy, according to numerous demographics textbooks and the E.U. demographics department, one of the best, if not the best, indicators of population health is the expected number of years without disability or disease: healthy life expectancy. Its detractors have yet to come up with a better one. Let's see how that pans out. This paper has plenty of details, methods, etc, and nifty graphics on healthy life expectancy: http://www.who.int/healthinfo/paper38.pdf No evidence of special benefit to high altitude locales. Easier to look at: healthy life expectancy ranking http://www.photius.com/rankings/healthy_life_table2.html Conclusion: AH1 makes all sorts of claims for which he has no evidence, cites papers as evidence of assertions of his that the papers in fact do not support, misunderstands his own cites and that of others, selects quotes in his and others' citations, makes sweeping statements not supported by any evidence existing out there, adjusts his language when he's caught spewing nonsense. Impressive. This time I'm really done. I'd advise all to resist temptation better than me and NFTT. -
Bob Lacatena at 14:13 PM on 21 September 2012It's not bad
AHuntington1, I'll make it easy for you. 1. My statement is that your statement about mitochondrial respiration is irrelevant, because the negative impacts of temperature and water availability will vastly outweigh any possible positive influence on mitochondrial respiration. 2. There is no actual evidence that increases in atmospheric CO2 will result in improved health for any fauna through improved mitochondrial respiration. If you are in opposition to either of these statements, you are asked to supply specific references that clearly support your position. You are also asked to paste in the quotes of any segments from the conclusions which support your position (simply providing links to papers and claiming that they support your position will not be adequate, because it leaves you with too much latitude to simply fudge it). -

Composer99 at 12:38 PM on 21 September 2012PBS False Balance Hour - What's Up With That?
Between the (IMO highly disingenuous) potshots at NOAA, the tiresome reference to Galileo, and rhetoric such as:Have you forgotten the most basic principle of science, falsifying the null hypothesis.
I must say fretslider appears to be trying to frame the discussion on this thread in a manner better suited to climate pseudoskepticism, a framing which I for one categorically reject. The attempt to sidestep the massive body of physics, paleoclimate reconstruction, empirical observation, and experimental support undergirding the mainstream understanding of Earth climate (and supporting the consensus position on climate change) with reference to poorly-defined (at the immediate point of use), much-abused concepts from the philosophy or practice of science (as a process) is a behaviour which I personally find infuriating (as compared to conspiracy-mongering, which is amusing). It is IMO exactly this sort of behaviour that fretslider is engaging in with this sort of nonsense (which also IMO happens to be a personal attack - by oh-so-careful insinuation - against DSL, at least if DSL is a practicing scientist). Bluntly put, the four pillars supporting consensus climate science - theory, paleoclimate, experiment, observations - are of such size and robustness that they handily falsify any would-be "null hypothesis" which attempts to eliminate or minimize the human element in the modern climate change we find ourselves in - a change, I might add, which is occuring at breack-neck pace (however slowly it might be perceived). Many self-styled skeptics have been asked to pony up the evidence to support their positions and have fallen short (or fallen silent). So I appeal to fretslider to dispense with the snide innuendo and empty philosophy and get down to providing evidence. -
Extreme weather isn't caused by global warming
Pardon my confusion, AHuntington. I was responding to this claim of yours @ 47: "From an ecological perspective, desertification is almost strictly a land management problem." and then especially this: "DSL, if you believe that human emissions of fossil fuels, and human errors such as overgrazing, deforestation, etc are causing desertification, you believe that all desertification is anthropogenic. Isn't this correct? What aspects of desertification are not anthropogenic?" and now you give me this: "I agree completely, and add that since humans have existed on earth, we have become a factor that can either rapidly intensify natural desertification and ecosystem breakdown, or promote biodiversity, and ecosystem growth." which I agree with. The second quote suggests that you were not aware of any natural mechanisms for desertification. I'm suggesting that you be a little more precise in your presentation. Your first quote could be excused because you did say "anthropogenic desertification" in the preceding paragraph. The second quote is an inexcusable non sequitur: it does not follow that if I believe the enhanced greenhouse effect can cause desertification that I then must believe that all desertification is human caused. -

AHuntington1, 1) You have not supplied a single citation which proves your point. 2) It is a "strawman" only because you refuse to address the point. A positive which is outweighed by the negatives is of no value. It is a simple reality. The fact that you want to ignore that reality does not make it a strawman, it makes it an argument you want to avoid because it's one you can't win. Let me state it more clearly, then: Your point that CO2 will provide the benefit of improving mitochondrial respiration, true or false, is irrelevant because it ignores the other greater, negative impacts associated with CO2. -

anon1234 at 10:55 AM on 21 September 2012It's not bad
doug_bostrom, what attendant risks are you referring to? For humans to be negatively affected by atmospheric CO2 it would have to be over 4% (which is when deleterious effects begin occurring, if I remember correctly). Increasing atmospheric CO2 from 400 ppm to 10,000 ppm overnight would have negative health effects, but this is not very realistic. you asked, "What's the risk/benefit equation here? Be specific. For instance, for a person living in Dhaka, Bangladesh is the payoff worth it?" I have no idea- again it has to do with many other factors. Eg. if someone is starving or dehydrating increased CO2 would probably not be very effective. -
anon1234 at 10:34 AM on 21 September 2012Extreme weather isn't caused by global warming
DSL, Hadley-type circulation did exist prior to anthropogenic CO2 emissions increasing, this results in deserts with sporadic fluctuations in rainfall over time. As to why Hadley cells are widening, I was under the impression that you thought anthropogenic CO2 emissions were responsible. Thus the spreading of deserts or desertification would be anthropogenic. you said, " Desertification has occurred as large-scale circulation patterns have shifted in response to major forcings over the course of Earth's history. " I agree completely, and add that since humans have existed on earth, we have become a factor that can either rapidly intensify natural desertification and ecosystem breakdown, or promote biodiversity, and ecosystem growth. Sphaerica, you said, "The main cause of deserts is the Hadley Cells (and in a few special cases altitude). This is readily apparent by noting that the latitudes at which deserts occur are the same (above and below the equator) and is readily explained by the mechanics of the Hadley Cells." 1. I never said that the Hadley cells weren't an important factor. They are not the only factor however, this is apparent when looking at this graph: http://www.ciesin.columbia.edu/docs/002-193/fig5.gif Notice the northern arid regions that are experiencing desertification. 2. I feel like you are missing my argument, but because I have tried to explain myself (and you seemingly ignore my points) and you haven't posed any specific questions re the information I have presented, I will not elaborate further (unless you have specific questions or criticisms of the points I am making, of course). you said, "some of those arguments will be valid in some cases, but this does not change the fact that one major, unavoidable and already observed effect of global warming will be the expansion of the Hadley Cells, which will in turn necessarily and proportionally expand the existing deserts poleward." Well good, we are in complete agreement on this point. -

fretslider - consider for moment that it is proved that there is too many errors in the surface temperature record for it to be a reliable indicator of climate. Now how do you explain away the same signal, same trend in satellite MSU readings ( UAH, RSS). How about global glacial mass loss, or OHC? It is the consilience of independent measures that gives strength to the science (and confidence that the surface temperature record is useful). -
Doug Bostrom at 10:02 AM on 21 September 2012It's not bad
Let's rinse and repeat, ahuntington1, since we've been through the citation mill again and still have not heard any specific claims useful for evaluating whether metabolic benefits of increased atmospheric C02 concentration might be worth attendant risks. Can you describe specifically how one's day might be so much better breathing an atmosphere with a higher C02 concentration? What would a subject notice? What would be the impact on mortality and susceptibility to adverse health experiences? What's the payoff outside of a test tube? If you can show in concrete terms how the population stands to benefit from increased C02 respiration, how likely are the specific benefits you've shown? Certain? Sometimes? Almost never? What's the risk/benefit equation here? Be specific. For instance, for a person living in Dhaka, Bangladesh is the payoff worth it? -

Dale, did you post this at WUWT Is it true? It is possible to post something but forget the exact words later on.. Same question to the mods, did any of you edit Dale's comment here? Do any of you ever edit comments? I can say with certainty that none of my comments have ever been edited here.Moderator Response: [d_b] Edits to comments are rare and will be explicitly pointed out by moderators. Such edits might be performed if a comment is of high merit but the author slipped up and was gratuitously rude, that sort of thing, with an eye to cleaning up the comment so as to comport with moderation policy.

Sphaerica, you said, "You haven't established benefits that CO2 exhibits on organisms, you've merely claimed them." Well, way to ignore all of the evidence I have supplied so far. Please address my info, or stop posting. you also said, "Because I live in the real world, where imagined minor benefits do not outweigh proven major drawbacks." You are still attacking the same strawman... you say, "it is silly to make the presumption that increased CO2 will be beneficial to all species equally. In fact, try reading this article." Ok, well here's a new strawman, at least. Where did I ever say that elevated CO2 would be beneficial to all species equally? Where are you getting this from, if you don't mind me asking? Bottom line: consistently attacking strawmen and using red herrings does not make a point, nor even come close to proving me wrong. Implying that I do not live in the "real world" and that I am "imagining" things, drawing up bogus comparisons between CO2 and cyanide, using red herringss to distract from my point- these things are not acceptable in a scientific discussion and some of them border on ad hominem attacks. I will not engage in a discussion with you until you display the ability to carry on a respectable, scientific dialogue. -

I apologise, I didn't notice the msg till pointed out just now. John @148: I've probably posted what, 5 or 6 times at WUWT in the last couple of months? And in I think two of them I mention this site. Neither inflammatory or derisively. Please get your facts together first.Moderator Response:[DB] As Eric(skeptic) notes below, your very own words hoist thee by thine own petard.

As typical of SkS I posted a comment (not insulting, but a summary of Mandia’s review to prove to the dolts I’d actually read the reviews) and it was deleted by John Cook. Asking if my deleted post breached comment policy also got deleted. I also notice my original comment was “amended”. I’d originally said:
“The book looks to be more about Mann’s sob story than any real science.”
It now reads:
“But since the book looks to be more about Mann’s sob story than any real science, I wouldn’t have read it regardless.”
SkS at its finest.
Note that when inflammatory comments are needfully moderated at SkS, the offending text is hidden with html text rather than deleted. This makes it possible to later show what the offending, "excised", text actually was in the first place.
In the interest of full transparency and to illustrate the impoverishment of Dale's position, here is the original comment that Dale made at SkS in its entirety, unedited:
As a reader of both sites (SkS and WUWT) and having read the Amazon reviews, I must admit to being disappointed by both sides.
It's obvious that both "sides" are going in and contaminating the waters. The negative reviews slamming Mann and the book in my opinion are the same as the positive reviews literally fawning over Mann like he's a deity.
To be honest, if I were looking to buy this I would be ignoring all of the reviews as it's obvious posturing by both "sides". But since the book looks to be more about Mann's sob story than any real science, I wouldn't have read it regardless.
Climate denial at its embodied finest.
A mental retard who is clueless not only about current events, but also has the IQ level of a rock.
Nope. Nothing inflammatory nor derisive about that.

One interesting takeaway from the upcoming Lars Larson segment will be the opportunity for the "what's that little horizontal bar next to the number" aka "negative and positive: never the twain shall meet" problem to be cleared up. If inability to deal with adding a positive to a negative is repeated on a nationally broadcast radio program that'll be a very sad thing. Listen for "110%," if you bother to listen at all. -

Dale #147: You have some potential to make an interesting point here, but unfortunately with several misconceptions ... namely that you think melting of the Arctic sea ice cap is largely without serious consequences. But what's happening? You are changing a large shiny white and dry part of the Northern Hemisphere to be a large dark absorbant and humid part of the NH. That is extremely likely to significantly change weather patterns in the Northern Hemisphere, perhaps very substantially indeed. Meteorologically, the Arctic may become a region dominated by low pressure and rising air, rather than high pressure and descending air. As whether the observed changes in the jetstream will have an impact, in the words of Jennifer Francis, "How can it not?" Of course, you may think that fundamentally altering the weather patterns across the Northern Hemisphere, where most of the world's food is grown, is of little consequence, but I would disagree. And that's without considering the consequences for Greenland (likely enhanced melt and SLR). We need to be very concerned about the Arctic.
