  1. A Hack by Any Other Name — Part 2

    Russ,

    You say "I could name many prominent individuals who have done exactly that.", but you do not name a single one.  This is political sloganeering and is not allowed at SkS.  You frequently assert that you are correct without any data to support your wild claims.  By contrast, Tom provided links to peer reviewed data.  Provide a list if you have names or do not make your unsupported claims.  When you do not provide data to support your claims you are conceeding the point.  Since you have provided no names you have conceeded that you cannot find them.

    You have the same habit with your claims about the science.  Provide data links to support your wild claims.

  2. The epidemic of climate science false balance in the media

    How long do we have to read Dana's mantra about 97%. It just gives deniers more ammunition to fuel the fire. Get real. Most scientists who know anything about this agree we have global warming, ditto that CO2 contributes to GW, and ditto that Humans are the main cause for the present rise in CO2. So lets get on with the stuff thats really important - how critical is it - and what do we do about it. If the BBC were to allow only blatant onesided arguments from folks such as dana then we would be just as insensed as if they only listened to Lord Lawson. The very one sided propaganda nature of the debate is in my opinion why the public are losing sight of the real issues.

  3. The epidemic of climate science false balance in the media

    As I've mentioned on a couple of other blogs recently, I can’t actually think of any British climate scientist with a record of published research who is a sceptic, so maybe it isn’t surprising that Nigel Lawson always gets the call to provide "balance".

    If the BBC is consistent, maybe we'll be hearing the views of John Major on quantum mechanics or Kenneth Clarke on superstring theory.

  4. A Hack by Any Other Name — Part 2

    Andy... Looking at the Monbiot link, I think he's using the event as a means to bring up other sociopolitical issues, which sort of mirrors my comment @8 about exploring the issue.

    "I believe we have a right to know who is paying for public advocacy. The groups which call themselves thinktanks but look to me more like lobbying organisations working on behalf of corporations and multi-millionaires, exist to try to change public policy. Yet, with a few exceptions, they operate in a vacuum of accountability."

    So, while I don't agree that Gleick's actions are justifiable, I think the event, in-and-of-itself, presented the opportunity to discuss other tangential but equally important issues. 

  5. Humidity is falling

    dwm:  I strongly suspect that Bob Loblaw is correct about your intention.  But I'll try one more time:  You are incorrect in expecting scientists to say that they are absolutely certain about anything.  One of the criteria for writing a good scientific paper for peer-review and then publication is to always describe what further research should be done; usually that means describing ways in which your own research that you have described in this paper fails to answer all the questions anyone might have.  Such admissions of shortcomings are not appropriately interpreted as implying that the currently reported research is inadequate for drawing any conclusions.  But that, as Bob pointed out, is what you are doing.  The question always is what conclusions are adequately supportable by this research.  As scaddenp pointed out, Gentleman and Fu concluded their research was sufficient for the purpose of modeling OLR.  Similarly, the Science of Doom blog author concluded:

    Still, that’s a different story from acknowledging that climate models attempt to calculate humidity from some kind of physics but believing that these climate models get it wrong. That is of course very possible.

    At least from this paper we can see that over this short time period, not subject to strong ENSO fluctuations or significant climate change, the satellite date shows upper tropospheric humidity increasing with surface temperature. And the CAM model produces similar results.

    A broader survey of the literature was done by the IPCC.  Their conclusion that I quoted to you earlier is that the empirical evidence is more than sufficient.  Your opinion to the contrary is meaningless unless you can cite specific, concrete reasons for the empirical evidence being insufficient for the purpose to which the IPCC is using it.

  6. A Hack by Any Other Name — Part 2

    I think that there are some intreresting comparisons to be made between the Gleick case and the SkS hack. While there were a few who applauded Gleick (eg George Monbiot) many more were critical of his ethics, some harshly so. Peter Gleick himself apologized. The released material comprised budget documents and strategic plans. Released documents that contained personal information about Heartland board members was taken down.

    There was no need to hack SkS to find out our budget or strategy, anyone who asked could find out: a few bucks raised by donations to pay for webhosting, no payments to contributors, no secret paymaster. Our strategy is to keep doing what we have been doing.

    The SkS hacker must have been disappointed. All he got was confirmation of all of the above and a few intemperate comments of the kind that people make when they are chatting and venting privately among friends. Mostly, the conversation was earnest (and usually rather boring) discussion about getting the science right.

    In contrast, many of those sympathetic to the SkS hacker continue to deny that there was even a break-in. We had faulty locks, they say, so even if there was a break-in, SkS deserved it: in other words, blame the victim, plea contributory negligence. The hacker himself does not dare to come forward, even anonymously, to say what happened.

    And, among those who have published our private conversations and personal information, we hear very little in the way of doubt or questioning that this might or might not be justifiable.

  7. A Hack by Any Other Name — Part 2

    Russ... 

    Yes, please do tell. You're going to need to support that statement.

    What is absurd is to conflate a moral lapse with an extended, intentional criminal attack. 

    Think of it this way. It's the difference between having had an affair while married, and forcably beating and raping someone.

    Both are wrong but the two are not comparable. I am insulted because I have been personally affected by the hacking and you are showing a callous incapacity to see the relevant severity of the two acts.

  8. Denialgate - Internal Heartland Documents Expose Climate Denial Funding Network

    Russ R. - Considering that the document in question was anonymously sent to Gleick in hard copy, prompting the social engineering he did to get the rest of the documents, that document (with appropriate caveats due to the lack of provenance) is the least morally questionable of the papers involved. It wasn't stolen, and is entirely consistent with the content of other documents Heartland has acknowledged to be real. 

    It's still up at DesmogBlog, too.

    The epidemic of climate science false balance in the media

    These "balancing" or "Alternative point of view" claims are definitely not about improving the best understanding of the science, or about developing the best understanding of what needs to be done.

    Lawson and many other very powerful business and political figures have devoted their entire life's effort to the promotion of benefit for the few for a short-time, pushing all they can get away with to make it easier for wealth to be obtained from many unsustainable and damaging activities, including, but not limited to, the burning of fossil fuels.

    Only a fool, or a person who shares the deep desire to maximize the short-term benefit for the few from unsustainable and damaging activities, would consider that type of person to be a reasonable party to invite to comment on the merits of "undoing all their life's work, just for the benefit of future generations who have no vote and have no money to spend today".

    The future of humanity requires leaders who will genuinely push for the rapid development of sustainable ways of living, in spite of the popularity or proifitability that can be 'created by the fallible actions of greedy people". The sooner these type of people are unable to get away with their unacceptable desires the better it will be for everyone else.

    It needs to be clear that there is a real "Us vs. Them" battle to be fought. Unsustainable and damaging activities threaten the sustainability of economies, societies, and humanity's future on this amazing planet.

  10. Denialgate - Internal Heartland Documents Expose Climate Denial Funding Network

    Contradicting the claim above in "UPDATE 2" that "the link to the climate strategy document below has been removed, as Heartland disputes its authenticity.", I should bring to your attention that 2 years later, this page is still quoting from and linking to the fake "Confidential Memo: 2012 Heartland Climate Strategy" document.

    I'm assuming this is merely an oversight that will be corrected.

  11. A Hack by Any Other Name — Part 2

    Gosh, do tell. Who are these people who didnt think this was a serious error of judgement?

  12. A Hack by Any Other Name — Part 2

    Rob Honeycutt,

    "As well, no one that I know of has ever condoned Gleick's actions."

    Then you are indeed fortunate.  I could name many prominent individuals who have done exactly that.

    "But it's absurd to compare that to the CRU and SkS hacks where people have systematically, deliberated, and with malice of forethought, perpetrated very serious crimes."

    Would you be so kind as to explain what is so "absurd" about the comparison?   Assuming the SkS hacker did indeed gain unauthorized access to obtain private information and leaked it publicly, how does that differ from Peter Gleick's actions?

    "I find Russ' comparison insulting and a deliberate attempt at distraction from the issue at hand."

    I can't imagine why you would feel insulted.  I never mentioned you, nor did I suggest you would support Gleick's actions.  And it's hardly a "distraction for the issue at hand". You were the one who mentioned "people out there with such low standards of morality as to believe it's okay to do this".  I simply provided an example.

    "If he wishes to discuss the merits of whether or not the Heartland docs should be posted on SkS, it should be done on that thread, not here."

    I already noted above that "I have no issue with SkS continuing to link to the real Heartland documents..."   But fair enough, I'll move discussion of the fake document to the other thread.

  13. The epidemic of climate science false balance in the media

    I can't help but to wonder if a contrarian such as Judith Curry would have any name recognition at all (outside of the small number of climate scientists working in her area of expertise) if not for this mindless pursuit of "balance" by journalists.  It can elevate a relative mediocrity to genius (celebrity?) status. 

  14. Humidity is falling

    dwm - firstly I note that you are reading links, which is good, but to defend your position why do you need to do so? I would assume that you would adopt a position on the basis of papers you have read or had least been reported on but so far you havent shown us what these were.

    Second, it is a bit of a stunning leap to jump from the bolded quote to your conclusions. In particular, why are historical values of any importance to climate models? Also, you seem to have missed the actual conclusion of the Gentleman and Fu paper. The important point is that if climate models had it badly wrong, then they would not be modelling OLR which is sum of those processes.

     

    For Spencer, I have responded to you here.

  15. Nazis, shoddy science, and the climate contrarian credibility gap

    Responding from another thread:

    As to Spencer - well: "I view my job a little like a legislator, supported by the taxpayer, to protect the interests of the taxpayer and to minimize the role of government."

    I have a preferrence for scientists who see their job as finding out what is not known and creating useful theories; but my main objection to Spencer is his actual attempts at science and serial misinformation. More about that here but check out the articles for yourself. He can say what he likes on blogs, but for credibility in science you have to back those assertions which he has consisitantly failed to do. In short, Spencer position on a matter of science seems instead to be an ideological one. Proposed solutions to climate change dont fit the ideology and he would appear to be bankrupt of alternative suggestions which do fit his ideology, ergo climate change must be natural. Yeah, right.

  16. The epidemic of climate science false balance in the media

    I remember the late BBC One Planet podcast, that covered environmental issues: they had this "balance" in their interviews, giving space to the likes of Richard Lindzen and letting him get away with claims like "high sensitivity is just the result of biased models" or that the reason for virtually the whole scientific comunity to support climate action was "vested interests".

    This podcast has had its good moments, but bad moments like this made me feel less sorry for them being cut off.

  17. A Hack by Any Other Name — Part 2

    Tom...  There are certainly people out there who condone Peter's actions, and I don't think they are right to do so, especially seeing as Peter doesn't condone Peter's actions. Those folks are far and few.

    I also think there are private discussions about Peter's actions where people float such views for the purposes of exploring the issue, but without making a public declaration that they would condone his actions.

    I find Russ' comparison insulting and a deliberate attempt at distraction from the issue at hand.

    If he wishes to discuss the merits of whether or not the Heartland docs should be posted on SkS, it should be done on that thread, not here. Conflating the two events is not warranted.

  18. Humidity is falling

    I meant to mention, Tom, that I’m glad you brought up AQUA. Here are a couple of statements by Dr. Spencer’s who is the U.S. Science Team leader for the Advanced Microwave Scanning Radiometer flying on NASA’s Aqua satellite.

    "we do not have enough accurate global data for a long enough period of time to see whether there are natural warming mechanisms at work”

    "the climate system is quite insensitive to humanity’s greenhouse gas emissions and aerosol pollution."

    He has a website if you'd be open to checking out an alternative viewpoint.

  19. A Hack by Any Other Name — Part 2

    Rob Honeycutt @6, my take is somewhat different, in that I believe I have encountered people who have condoned Gleick's actions.  They have done so either on the grounds that the situation is now so desperate with regard to climate change that the end justifies the means; or the grounds that once "skeptics" began hacking and publishing the internal emails of scientists (and The Heartland Institute certainly republished them), they set a standard whereby they wished to be treated (ie, "Sauce for the goose is sauce for the gander").  

    Personally, I believe that neither attitude is correct.  Indeed, given that SkS has frequently moderated posts to delete links to either the UEA emails (I believe), or to draft versions of IPCC AR5 on the grounds that the information was obtained unethically, I think SkS as a matter of consistency should not link the the Heartland Institute documents.  Either that or change its moderation policy to allow links to hacked or unethically leaked material that we consider unethically obtained, and/or published.  Of the two, I believe the former to be the better approach.

     

     

  20. The epidemic of climate science false balance in the media

    The response by the BBC reported by MA Rodger @1 could be annotated thus

    Whilst there may be a scientific consensus about global warming - that it is happening and largely man-made - there is no similar agreement about what should be done to tackle it; whether money should be spent, for example, on cutting carbon emissions or would be better used adapting our defences to the changing climate. Lord Lawson is not a scientist, but as a former Chancellor of the Exchequer is well qualified to comment on the economic arguments, which are a legitimate area for debate.


    Maybe, but Lord Lawson was not invited to discuss the economic arguments, he was discussing whether the recent extreme rainfall in the UK was linked to climate change. That is not an "economic argument". Moreover he was put up against a climate  scientist whose area of expertese is not economics.  Why ?

    We believe there has to be space in the BBC’s coverage where scientific consensus meets reasonable argument about the policy implications of that consensus view.

    If that is the case, then again why was Sir Brian Hoskins invited to take part, since he is not a policy maker ? Moreover the implication of this statement by the BBC appears to be that, somehow disliking the policy implications of climate change is sufficient reason to doubt the physical science - which is a nonsensical position. There is aboslutely no reason why the scientific consensus on global warming should "meet" arguments about the policy implications; because the policy can have no influence on physics.

    That said we do accept that we could have offered a clearer description of the sceptical position taken by Lord Lawson and the Global Warming Policy Foundation in the introduction. That would have clarified in the audience’s minds the ideological background to the arguments.

    Perhaps they should have included this too

  21. A Hack by Any Other Name — Part 2

    Russ R...  As well, no one that I know of has ever condoned Gleick's actions. But it's absurd to compare that to the CRU and SkS hacks where people have systematically, deliberated, and with malice of forethought, perpetrated very serious crimes.

  22. Nazis, shoddy science, and the climate contrarian credibility gap

    mgardner said:

    "So, rather than respond at the level appropriate to the debate as presented by skeptics, and the audience it is aimed at, they foster the impression that rebuttal requires an ever-more complex analysis. "

    One of my goals is to create an ever more simple analysis and not rely on GCMs.  Skeptics should like that.  One approach I take is to include factors that alternative theory scientists such as Scafetta and Curry want to see in the models. Skeptics should also like that. 

    What I am finding that skeptics don't like, is that even with all this bowing to their wishes, when the results don't agree with their preset notiions they still complain.

    The goal-posts will always move.

     

     

  23. A Hack by Any Other Name — Part 2

    Russ R...  Interestingly, Peter Gleick, himself, stated that he believed it was wrong what he did, that he definitely had a lapse in judgement. 

    Has anyone done the same after the CRU hack? Has anyone bravely apologized for the SkS hack?

  24. A Hack by Any Other Name — Part 2

    "And it's just phenominal to me that there are people out there with such low standards of morality as to believe it's okay to do this."

    Peter Gleick, for example... and those who condone his actions in phishing and leaking documents from the Heartland Institute.

    By the way, just thought I should let you know that SkS is still quoting from and linking to the 2-yr old fake "Confidential Memo: 2012 Heartland Climate Strategy" document of which Gleick denies authorship.  (http://www.skepticalscience.com/denialgate-heartland.html).  I'm assuming this is merely an oversight that will be corrected.

    N.B.

    • I accept on good faith that SkS' editors intended to remove links to the fake document, and simply missed one link and a few quotations.
    • I have no issue with SkS continuing to link to the real Heartland documents despite the "low standards of morality" employed in their acquisition.
    • I commend SkS for removing those documents that contain individuals' personal information.
    • I do not support the Heartland Institute in any way.
    • I do not condone the actions of whoever hacked SkS.
  25. Humidity is falling

    Hi Tom,(-snip-)


    I am familiar with the water vapor articles on the Doom site, but I hadn't read the latest, thank you for that.

    Looking it over, I found several qualifying statements in the article that basically agree with the opinions I have been posting.  You seem to have missed them so here they are:

    This quote from Doom corroborates exactly what I said (in bold):
    "A major problem with analyzing UTWV is that most historic measurements are poor for this region. The upper troposphere is very cold and very dry – two issues that cause significant problems for radiosondes."
    This quote from Doom also agrees with what I wrote, water vapour is a critical issue (hence potential weak spot), and it is massively complex (hence hard to calculate and easy to get wrong, exhaustive study is necessary before having confidence):
    "The question of how water vapor responds to increasing surface temperature is a critical one in climate research.
    vapor concentration in the free troposphere is dependent on the global circulation, making it dependent on the massive complexity of atmospheric dynamics."
    This quote from Doom concedes it is "very possible" that climate models get it "wrong" when he writes that
    some people may “acknowledge that climate models attempt to calculate humidity from some kind of physics but believe that these climate models get it wrong. That is of course very possible."

    Gettelman & Fu concede that their short (and scattered) data sample by itself is “not sufficient”, or in other words, only one step in a long road yet ahead before we can conclude with confidence that the models are accurate:
    "The hypothesis we seek to test is whether water vapor in the model responds to changes in surface temperatures in a manner similar to the observations. This can be viewed as a necessary but not sufficient condition for the model to reproduce the upper-tropospheric water vapor feedback caused by external forcings such as anthropogenic greenhouse gas emissions."

    Moderator Response:

    [Dikran Marsupial] Moderation complaints snipped.  Moderation complaints are by definition off-topic and will be deleted (after reading).  I have snipped the moderation complaint this time, but in future the whole comment will be deleted as moderators do not have the time to edit posts.  If you want to make a substantive point, leave the moderation complaints out of it.  Please read the comments policy and abide by it, compliance is non-negotiable.

  26. The epidemic of climate science false balance in the media

    Among Climate Scientists, the agreement about Global Warming is 100%.  Most believe the sensitivity is above 2C per doubling of CO2.  A very few believe its below 2C.  But there are no Climate Scientists, none, who disbelieve the idea altogether.  This is a point that the public needs to be made more aware of.  Its the reason Climate Deniers say their argument is with CAGW, not AGW, because it allows them to weasel out of their advocacy like a lawyer if you manage to nail them down on specifics.

  27. The epidemic of climate science false balance in the media

    Any fool can look at detailed budget slashing at DEFRA and decode what the Conservatives actually think about climate change. Meanwhile the BBC's been on the wrong foot recently for a number of reasons, are vulnerable and hence need to be careful not to offend the wrong people. 

    Folks don't rise to the top of management with a tin ear. Tone is set from the top. It's all a matter of listening.  

  28. Humidity is falling

    In terms of quantifying feedback, there are well-acknowledged uncertainities in what the value of climate sensitivity is. However, you have asserted " we understand very little of the complex interactions of having different humidities in different layers of the atmosphere and in different regions of the earth"  and I cant find backing for this in science that I am aware of. 

    Geoengineering is discussed as only as method of last resort if humanity doesnt do the obvious step - reduce emissions. Reducing emissions is safe, since it takes us to takes us back to known state. Since you accept the precautionary principle, I assume you are good with that.

  29. The epidemic of climate science false balance in the media

    The BBC have got appalling at covering climate change over the last two or three years.
    The recent storms have been devastating in the UK and follows up on the year of flooding in 2012.

    In over two months of bad weather and extreme flooding, the BBC completely failed to look at climate change or ask scientists about the weather. Instead they happily gave the voice of a  Somerset MP who has a background of opposing wind farms and blamed the Environment Agency for failing to cope with record rain fall.

    I have to say, but don't like to, the changes have come about since the last election.
    It may be coincidence, but given that we have a government here that has a Prime Minister that refuses to acknowledge that he has appointed climate change deniers in some key positions, the BBC should be challenging the views of various government officials and politicians that they interview.

    Plus of course Labour did their bit by fueling the arguements last year about energy bills, which lit the touch paper that launched attacks on renewable energy.

  30. The epidemic of climate science false balance in the media

    MA Rodger: The BBC's response seems especially inapt given what Lawson actually spent his time arguing about (the science).

  31. The epidemic of climate science false balance in the media

    Some hope from NBC News

  32. The epidemic of climate science false balance in the media

    I put a complaint in to the BBC about Lawson's appearance on Radio 4 because "almost every point he made was woefully wrong."

    The reply I got back from the BBC was:-

    Whilst there may be a scientific consensus about global warming - that it is happening and largely man-made - there is no similar agreement about what should be done to tackle it; whether money should be spent, for example, on cutting carbon emissions or would be better used adapting our defences to the changing climate. Lord Lawson is not a scientist, but as a former Chancellor of the Exchequer is well qualified to comment on the economic arguments, which are a legitimate area for debate.

    We believe there has to be space in the BBC’s coverage where scientific consensus meets reasonable argument about the policy implications of that consensus view. That said we do accept that we could have offered a clearer description of the sceptical position taken by Lord Lawson and the Global Warming Policy Foundation in the introduction. That would have clarified in the audience’s minds the ideological background to the arguments.


    It smacks of an excuse of the moment rather than a proper explanation.

    My own explanation is that the many 'swivel-eyed loons' within the Tory party had been applying a lot of pressure on climate (and may be other things as well) and the BBC caved in.

  33. 2014 SkS Weekly News Roundup #9A

    Non-Scientist:

    I must disagree strongly with your characterization. There is no hint of what you suggest regarding "buying a Prius".

    Here is the abstract of the paper discussed in the Reuters article:

    It is widely assumed by policymakers and health professionals that the harmful health impacts of anthropogenic climate change1, 2, 3 will be partially offset by a decline in excess winter deaths (EWDs) in temperate countries, as winters warm4, 5, 6. Recent UK government reports state that winter warming will decrease EWDs7, 8. Over the past few decades, however, the UK and other temperate countries have simultaneously experienced better housing, improved health care, higher incomes and greater awareness of the risks of cold. The link between winter temperatures and EWDs may therefore no longer be as strong as before. Here we report on the key drivers that underlie year-to-year variations in EWDs. We found that the association of year-to-year variation in EWDs with the number of cold days in winter ( <5 °C), evident until the mid 1970s, has disappeared, leaving only the incidence of influenza-like illnesses to explain any of the year-to-year variation in EWDs in the past decade. Although EWDs evidently do exist, winter cold severity no longer predicts the numbers affected. We conclude that no evidence exists that EWDs in England and Wales will fall if winters warm with climate change. These findings have important implications for climate change health adaptation policies. [Emphasis mine.]

    In short, excess winter mortality no longer seems related to winter conditions themselves, but to the varying deadliness of seasonal influenza and its relatives - the paper analyses the expectation that excess winter deaths will decrease due to milder winters and finds that there is little room for improvement. (It must be said that this is a single paper, so some corroboration is surely required before it is taken as fact.)

    The headline itself is nothing more than a literal one-sentence summary of the findings of the paper as noted in the abstract.

    It's also worth noting the risk factors for mortality/morbidity for heat illness:

    Age. Infants and children up to age 4, and adults over age 65, are particularly vulnerable because they adjust to heat more slowly than other people.

    Certain health conditions. These include heart, lung, or kidney disease, obesity or underweight, high blood pressure, diabetes, mental illness, sickle cell trait, alcoholism, sunburn, and any conditions that cause fever. People with diabetes are at increased risk of emergency room visits, hospitalization, and death from heat-related illness and may be especially likely to underestimate their risk during heat waves.

    Medications. These include diuretics, sedatives, tranquilizers, stimulants, some heart and blood pressure medications, and medications for psychiatric conditions.

    [Emphasis original.]

    Increased risk of heat illness is obviously a real risk of climate change, whatever your feelings about who dies from it. All this article does is show that we can't look to decreased winter mortality/morbidity to balance it off.

  36. 2014 SkS Weekly News Roundup #9A

    No edit function: For clarity, my last sentence would be better as "...mocked as insinuating..."

  37. 2014 SkS Weekly News Roundup #9A

    "Global warming won't cut winter deaths as hoped"

    This topic, and the related topic of summer heat induced death are a tad misleading. The death rate of all causes is 100%: you are going to die at some point, and today there will be a medical diagnosis other than old age. 

    But nearly all deaths due to summer heat are natural deaths of old age, and that is a quiet passing during one's sleep, rather than while hooked up to machines, after a painful fall, or due to a hospital aquired infection.

    It's best not to distract from the real risks of climate change with headlines which will be mocked as meaning "Millyuns will die in the streets if you don't buy a Prius".

    Global warming continues, but volcanoes are slowing down the warming of the atmosphere

    Its silly to imply climate models are getting it wrong when they are not designed to factor in certain aspects of the climate. Climate models should be adjusted each year to factor in increased ocean heat, volcano eruptions and what ever else is not accounted for.

    Its great to hear that the IPCC will now start to focus on ways to reduce the impacts of climate change. Its getting a little pointless when the only arguments we are hearing are conspiracy theory's.

  40. Global warming continues, but volcanoes are slowing down the warming of the atmosphere

    chriskoz @11.

    Klimont et al (2013) shows sulphate emissions to 2011. There is a balance between rising emissions in the developing world and falling emissions in the developed world. This also results in emissions increasing at lower latitudes.

  41. Global warming continues, but volcanoes are slowing down the warming of the atmosphere

    tstreet@9,

    Human aerosol emissions can be acounted for quite reasonably in the past 100y or so, as seen on this graph from tamino:

    sulphate emissions

    The emissions clearly peaked in 70s, after they started cleaning what you've experienced in Denver, and what other experienced throughout the whole NAmerica & Europe.

    I don't see any jump on this graph as the result of recent boom in China. The graph ends at 2000 however, and would love to see latest update on this account. But so far, I don't see anything what you describe as "what's going on in China" on this graph.

    So my conclusion: "if China cuts its emissions", there will be no "ugly spike in [global] warming", because the drop in aerosol emissions should not be very signifficant. Perhaps the local temps would be affected. But the global effect might well be diluted. Often, what looks grandiose & very scary (especially when seen through sensationalism of the media) may not be actually a big deal when seen through the actual data analysis.

  42. CO2 lags temperature

    I asked @433 "Anybody any ideas?" It appears from the comments @ 434, 435 & 436 that dwm's answer to this question is "No. I have no idea whatever."

    This still may not be the definitive answer to my question (dwm has not shown here much skill in providing such answers, even when well positioned to do so), so if anybody else has any ideas, I would be happy to learn of them.

    "Debunking Charles Krauthammer’s climate lies" is missing a link, which is here

    I hope everyone reads Krauthammer's piece as its a classic 'doubt is our product' piece of misinformation.  If 'doubt is your product' then you aren't served by shedding a light on the problem, in this case, of future climate.  Rather you are served by spray-painting out the light on the problem that's being shed by others.  Hence its extremely important for Krauthammer to claim that he doesn't know whether Global Warming is real or not, because it excuses his lack of prediction of future climate.  No light from him.  Despite this ambivalence, he is somehow 'certain' that the climate scientists don't know what they're talking about- no light from them.  This leaves us all stumbling around in the dark, supporting the fossil status quo, which is his intention.  Its also why I call such people graffiti taggers.  No constructing a bridge to the future for them.  Just spray-painting over the bridge constructed by others to make it look unpalatable.

    [JH] Thank you for bringing this omission to our attention. The link has been inserted.

  44. Humidity is falling

    scaddenp, I pointed out that we are all still waiting for a good source (of a data record), and I asked for a good source if you have one, so why are you asking me for my source?

    This is getting off topic, but since you asked.. I don't disagree with the precautionary principle. The problem lies with how you define precautionary.  For instance, I am alarmed by those who advocate for pro-active measures such as geoengineering based on climate science which is, in my opinion, still in its infant stage. 

  45. Humidity is falling

    dwm - are you seriously suggesting that Clausius-Clapeyron relation doesnt hold in the atmosphere? Furthermore water vapour are constrained by OLR measurement. What is your estimate (I would love to know your source...) that the error range in the humidity estimates invalidate model estimates.

    Next question, suppose for whatever reason you decide that you dont trust models are the best predictors of future climate, and yet the physics of AGW is not in doubt. What predictor of future climate do you suggest policy makers use which you think has better skill than climate models?

    Uncertainity cuts both ways. Suppose the errors are such that warming ends up much faster than predicted? The precautionary principle would seem to apply.

  46. Nazis, shoddy science, and the climate contrarian credibility gap

    Bob @49. Thanks, got it now. I pretty much understood you post, but your the visual from your link really made me see.

  47. Humidity is falling

    JH and others:  as I said, we are years away from having reliable humidity data for the various levels of the atmosphere, and moreover, as humidity is not uniform, we understand very little of the complex interactions of having different humidities in different layers of the atmosphere and in different regions of the earth.  The facts that we don't have the data, and that we don't understand the complexities of the interactions, don't allow you to indulge in the weak defense of "It's the old "if you don't know everything, you know nothing" gambit." 

    If that is not the case, please tell me where I can find the data showing humidity levels of all layers of the earth's atmosphere for the different regions, tropic, sub-tropic..., for the past century, or heck, how about just the past 20 years.

    Without a very good idea of what humidity leves have been, climate models are left in the "best guess" scenario, and since water vapor is the most important greenhouse gas, their reliability is very much in question.

    [JH] Your personal opinions matter little on this website. If you cannot document your assertions, merely repeating them constitutes sloganeering- which is prohibited by the SkS Comment Policy.

  48. Global warming continues, but volcanoes are slowing down the warming of the atmosphere

    You can get the historical radiative forcing from aerosols from the IPCC reports

    Aerosols have improved since 1990 but way worse than 1950. What matters from climate point of view is the net forcings. Aerosols have got worse but dont cool because overwhelmed by increased CO2.

  49. Global warming continues, but volcanoes are slowing down the warming of the atmosphere

    Someone else can probably be more quantitative, but I would think that the amount of heat reflecting emssions put out by China would be at least what the U.S. and others were emitting during the period when we had a significant cooling effect.  I do remember that pollution used to be a lot worse in places I have lived like Denver, but it doesn't seem close to comparing with what is going on in China. 

    However, I would be interested also in the actual quantitative impact on the results of the models and if the models try to take into account the cooling effect of ongoing heat refleting emissions. 

    If/when China cuts its emissions to that approaching western standards, it seems like this is going to cause an ugly spike in warming.

    Not sure how you come up with the destinations, but the first thing a hacker would do is to use a proxy(even with Tor), preferabily from a country not assocciated with his own.
