  1. Global Warming’s Missing Heat: Look Back In Anger (and considerable disbelief)…

    The link to this report is this:
    http://www.atmos.ucla.edu/~brianpm/download/charney_report.pdf
    Otherwise you get the main page of the lab website.

    This is a remarkable report, albeit short (kind of a summary for policymakers), in that it already contains most of the ingredients of this climate problematics, even if the models have been considerably refined. Moreover, more knowledge now means more uncertainties now, this is a kind of paradoxical law of science but quite logic, since many unknown unknowns have come out as known unknowns. More uncertainties mean also more fodder for contrarians, and in this context, it's important to keep eyesight on the big picture. Reading this report retrospectively greatly helps.

    Moderator Response:

    [GPW] Thanks for pointing that out - a missing tilde caused the problem - now fixed.

  2. It hasn't warmed since 1998

    I did some research and found out that the principle author, John C. Fyfe was a participant of the IPCC 4AR. So it would seem that he is not a denier, and is in fact a supporter. So I am not sure what to make of this comment: 

    source: http://hockeyschtick.blogspot.co.uk/2013/08/new-paper-finds-climate-models-have.html

    The inconsistency between observed and simulated global warming is even more striking for temperature trends computed over the past fifteen years (1998–2012). For this period, the observed trend of 0.05 ± 0.08 °C per decade is more than four times smaller than the average simulated trend of 0.21 ± 0.03 °C per decade (Fig. 1b). It is worth noting that the observed trend over this period — not significantly different from zero — suggests a temporary 'hiatus' in global warming.

    So, my question is, has it gotten warmer in the last 15 years, or not? Does it matter? If it doesn't matter, then why is he bringing it up? He doesn't really make a big deal about it in the rest of the paper, which seems mostly focused on the models. I get that the model isn't important to whether or not climate change is real, so that is not what my question is about.

  3. Global Warming’s Missing Heat: Look Back In Anger (and considerable disbelief)…

    A timely reminder that certain contrarian memes are false.

    This bears repeating:

    It seems to us quite possible that the capacity of the deeper oceans to absorb heat has been seriously underestimated, especially that of the intermediate waters of the subtropical gyres lying below the mixed layer and above the main thermo­cline.

    Also the absolutely central point that obsessing over TCR/ECS is a mistake. The true question is not climate sensitivity to 2xCO2 but ecosystem sensitivity to 2xCO2. Or higher.

  4. 2013 SkS Weekly News Roundup #37A

    There's plenty of discussion out there on the point.  Schneider and Trenberth dribble this football quite a bit.  The topic gets talked about in different spots at SkS, but I don't think there's a solid article on it.  Maybe Colose or SoD could do a guest post on it.  Trenberth did a rather plain English summary a few years ago, but I can't find it.

  5. 2013 SkS Weekly News Roundup #37A

    Here's a myth to add to your list:

    "

    There is an upper bound on global warming from water vapor condensation effects, when water evaporates from the surface it takes a lot of energy with it, when the water vapor condenses into droplets at high altitude it releases that thermal energy as long wave radiation. Because the condensation takes place at relatively high altitude the thermal energy released has an easier time escaping because a large portion of the greenhouse gasses that reflect long wave radiation are below the condensation layer.

    Because of this energy convection effect so long as Earth has surface water to evaporate and condense at high altitude there is a limit to how warm the surface can get."

    I've seen variations on this arguments articulated elsewhere, so it seems to be one that has some circulation. It seems to overlook the fact the water vapor itself is a GHG, so the fact that there is more of it in the atmosphere is going to "limit the limit" that is proposed here. But I'm sure you folks can find other ways this argument falls down or states only a small part of the truth in such a way as to be misleading.

  7. The Skeptical Science temperature trend calculator

    I'm trying to understand decimal month conventions for entering data.  The blog says if you enter 1990, that includes January 1990 data.  So if enter 1990 as a start date and 1991 as an end date, I would have 13 months of data, right? 

    What do I enter to include February data all the way through and including December of a particular year? (11 months of data).  One month in decimal form is 0.08.  So logically it would seem if I entered 1990.08 as a start and 1990.92 as an end, I would obtain February through and including December data?  Help me out here, please.



  8. Global imprint of climate change on marine life

    The rising and falling of "the jellies" on their 24 hour cycle may be an oceanic response to the need for the mixing of the upper strataof water.

    this of course, implies a "Gaia" state of consideration of the "Global Intelligence", which some pedents find objectionable, but...  this IS a board for discourse..

  12. Global imprint of climate change on marine life

    I apologise for going off-topic but this article by Tim Flannery in the New York Review of Books is a gripping must-read. The article is a review of the book  Stung! On Jellyfish Blooms and the Future of the Ocean by Lisa-Ann Gershwin. It is about the rapid growth of jellyfish populations worldwide as the ecological balance of shell and bone marine creatures, from anchovies to penguins, is disrupted.

    The book sounds like it is worth reading.

    They're Taking Over!

    I appreciate less dramatic, and probably more essential, owrk done by John and his colleagues described in the post.

     

  13. Arctic sea-ice 'growth', a manufactured IPCC 'crisis' and more: David Rose is at it again

    Just in case it's of interest to anyone here, I'm currently in discussions with both the Press Complaints Commission and The Mail about the inaccuracies in David Rose's article. More at:

  14. Arctic sea-ice 'growth', a manufactured IPCC 'crisis' and more: David Rose is at it again

    If you take the first sentence of Rose's Mail on Sunday article and search for it (in quotation marks) you'll find that it already achieves 28,000+ hits. If it's anything like previous Rose/Mail articles, over the next month or so that number will increase to 50,000+. That's why Rose writes such stuff -- he has a big denial echo chamber to feed. 

  15. It hasn't warmed since 1998

    Can anyone point out the errors in this recent paper?

    http://hockeyschtick.blogspot.co.uk/2013/08/new-paper-finds-climate-models-have.html

    For the most part it looks like another rehashing of the "we are actually cooling (or staying steady)" argument.

  16. Renewables can't provide baseload power

    All: I have deleted JvD's most recent post because it was sloganeering and repetitive.  

  17. Renewables can't provide baseload power

    JvD - "...since the external cost of nuclear energy is negligable (which Budischak confirms)"

    I'll simply note that for the Budischack et al paper the externalities of nuclear power were not part of the study. That doesn't mean they don't exist - waste disposal/storage, carbon cost of low-density fuel extraction (excavation isn't free), and the cleanup of nuclear accidents; difficult to quantify as those accidents are rare events, significant because they are very very expensive. 

    What would be your estimated external cost for the evacuation of an entire city, over 150,000 people, for a period of decades? As at Fukushima? Your claims that nuclear power has no external costs is disingenuous in the extreme - nothing is free. 

    That doesn't mean that nuclear power isn't a viable option. It does mean, however, that your arguments in support of nuclear power, for example this matter of externalities and your claim that the 1950's 'truck reactor' was a potentially usable design, are unbalanced and one-sided cheerleading. 

  18. Renewables can't provide baseload power

    JvD,

    a few points from someone who is broadly speaking, a supporter of nuclear.

    1) Your tone is aggressive, and counterproductive.

    [DB] Sloganeering and moderation complaints snipped.

  23. Renewables can't provide baseload power

    Further to JvD @90:

    "Budischak's conclusion is that a renewables electricity system would cost about 10 ct/kWh more than a nuclear-based electricity system, since the external cost of nuclear energy is negligable (which Budischak confirms)." (My emphasis)

    Tell that to the people of Okuma, Fukushima.

    I do have one more relevant opinion about nulear power.  That is that the announcements of overwhelming safety by people who favour nuclear power are simply not to be trusted.  Do not misundertand me.  The catastrophe at Fukushima is small scale compared to the prospect of global warming.  If the price of stopping global warming is a Fukushima a decade, and we cannot do it any other way, that is a price we ought to pay.  But the people who tell us the nuclear power is risk free, and (even more unbelievably) external cost free are the same people who were making jokes immediately after Fukushima about how the radiation release was less than the dose from eating a banana a year - until the real figures started leaking out.

    They were so confident about the safety of nuclear power that they did not recognize a genuine, and major emergency when it occurred.

    And yet they expect us to accept their blandishments about the safety of nuclear power as gospel.

    So when JvD asserts that "the external cost of nuclear energy is negligable" all that tells me is that his opinion on the safety of nuclear power is not to be trusted. 

    Moderator Response:

    [DB] All parties should confine comments about nuclear power to the pertinent and relevant areas of supplying baseload power.  The negatives of nuclear power, a la Fukushima, while pertinent in the real world and relevant in terms of being inclusive negative externalities of nuclear power, do not fall under the aegis of this thread and are thus off-topic from this point forward.

    This thread is about the ability of renewables to supply baseload power.  As such, discussions of nuclear power in a direct capacity are off-topic on this thread as well.

  24. Arctic sea-ice 'growth', a manufactured IPCC 'crisis' and more: David Rose is at it again

    The IPCC published a press-release setting the record straight about the end of September meeting:

  25. Debunking 97% Climate Consensus Denial

    One often-unsaid aspect of the public discussion on whether human-induced climate change is real, is ideology. Several months ago, the University of Kentucky hosted of forum on climate change with three excellent speakers who were all self-described conservatives. Liberals reported how they better understand that there are thoughtful conservative perspectives on, and solutions to, climate change, thus allowing for a broadened public discussion. In turn, conservatives in attendance learned the same thing. You can watch the recording of this event at http://bit.ly/135gvNa. The starting time for each speaker is noted at this page, so you can listen to the speakers of greatest interest to you.

  26. Renewables can't provide baseload power

    JvD @90, SkS does not "agree" with anything.  That is because SkS is a website, not a person.  The website is run by a number of volunteers who agree and disagree about many different things.  As you have already been invited to do, you are quite welcome to write a post making the case for a nuclear future to mitigate climate change.  Such a post will undergo the normal SkS "peer review" process, ie, any volunteers who are interested will look at the post, make comments about how it can be improved, and/or recommend it to be published, or not published.  Should it be published, it will not be the SkS view, but the opinion of JvD published on SkS (just as my posts on SkS are not the "SkS view", but just my opinions published on SkS).  However, if you are not prepared to put that effort in, you have no right to complain about the absence of such a post.  You will also have no right to complain if your repetitive brow beating is ruled off topic under other posts (as it mostly is - not to mention tedious).

    FYI, I have virtually no opinion on nuclear energy.  I am quite happy to have nuclear power as one of the options, but will not impede the already difficult political fight to do something effective about global warming by tying it to a nuclear agenda.  Beyond that, I am quite happy to just put a price on carbon and let the people actually building the power plants decide which will generate most  efficiently and hence give them the greater profit.

  27. Renewables can't provide baseload power

    @Michael,

    "Industry brag sheets?"

    I posted a peer-reviewed scientific article written up by the respectable Barry Brooks!

    And the video of Hansen I posted is relevant, because it directly contradicts the contents of the above article (and other articles on SkS) which is supposed to be part of the 'myth busting' series of SkS. You clearly don't like that, which is why you have now stated that James Hansen is wrong about renewables, nuclear and solving climate change, but you do not support your opinion. On the contrary, you turn around on and accuse me of not supporting my opinion! Even while I have presented clear arguments and provided literature supporting my views.

  28. Renewables can't provide baseload power

    Lastly, and that will be it for me unless I'm challenged to explain myself again. I realise that the nuclear energy issue is being prohibited from discussions about solving the climate crisis on certain discussion boards. I consider SkS better than that. Interestingly, James Hansen actually has an important thing to say about why actual solution to climate change (such as nuclear power) are often disparaged and ignored, here:

    http://www.columbia.edu/~jeh1/mailings/2011/20110729_BabyLauren.pdf

    The Easter Bunny and Tooth Fairy
    The insightful cynic will note: "Now I understand all the fossil fuel ads with windmills and solar panels – fossil fuel moguls know that renewables are no threat to the fossil fuel business." The tragedy is that many environmentalists line up on the side of the fossil fuel industry, advocating renewables as if they, plus energy efficiency, would solve the global climate change matter.


    Can renewable energies provide all of society's energy needs in the foreseeable future? It is
    conceivable in a few places, such as New Zealand and Norway. But suggesting that renewables
    will let us phase rapidly off fossil fuels in the United States, China, India, or the world as a whole is almost the equivalent of believing in the Easter Bunny and Tooth Fairy.

  29. Renewables can't provide baseload power

    JvD,

    SkS does not have a position on nuclear.  SkS exists to document and counter misconceptions about human caused global warming.  SkS takes the consensus position on issues where a consensus exists.  Hansen's position is an outlier, not a consensus position, and is not directly related to SkS goal of countering false information about global warming.  For those reasons SkS does not take a position on Hansens issue.  Without asking, I am sure that the people who post on SkS have a variety of opinions about your pet peeve, some support you and some do not.  You are not convincing anyone to support your position by constantly nagging others to do your work for you.  For example, I am agnostic about nuclear but you have labeled me as an extreme enviro against all nuclear.  Why are you so incorrect in your assessment of me?  It is due to your posting style which alienates even those who might support you.

    As has been pointed out to you many times before, SkS is run by volunteers who write the posts.  You are welcome to do the work and write a detailed post about nuclear supported by peer reviewed science,  Industry brag sheets are not generally considered peer reviewed, nor are online videos.  These types of posts come on SkS occasionally, like the one we are currently posting on, so it is likely to be posted.  Since you are unwilling to do the work to support your position you should stop complaining about others not doing your work for you.  By constantly repeating yourself  you are sloganeering which is against the comments policy.

    Moderator: if my comments about SkS policy are incorrect please delete this post, since I do not represent SkS.

  30. Renewables can't provide baseload power

    @Michael,

    There is ample literature that supports my view. For example:

    http://www.350.me.uk/TR/Hansen/BarryBrook.pdf

    Meanwhile, I notice that you have now stated that - according to you - James Hansen's opinion on renewables, nuclear power, and solving the climate crisis are wrong.

    It would be nice if you did your homework can proved that Hansen it wrong. Or do you suggest that I trust your private opinions on the subject at face value, rather than James Hansens!? ;)

  31. Renewables can't provide baseload power

    Technically, as discussed in the opening post, renewables are capable of baseload power, and are likely to be economical for that in many regions, with Budischak et al 2013 ("Cost-minimized combinations of wind power, solar power and electrochemical storage, powering the grid up to 99.9% of the time") a good example of actually running the numbers.

    I think you are minunderstanding Budischak's paper. Budischak concludes that it would not be economical at all!

    Budischak monetized and included the external cost of energy in order to arrive at the conclusion that a high-penetration renewables energy system would not be more expensive that today's energy including externalities. He uses a figure of about 10 ct/kWh for the cost of these externalities in today's mix. In other words: Budischak's conclusion is that a renewables electricity system would cost about 10 ct/kWh more than a nuclear-based electricity system, since the external cost of nuclear energy is negligable (which Budischak confirms). Budischak even includes expected future cost reductions of renewable energy systems, which means that using today's technology would be even more expensive.

    The correct conclusion to be drawn from Budischak is that nuclear is far more economical than renewables, because it does not have the negative externalities that fossil fuels have, nor does it have the high internal costs of renewables. That is why James Hansen is adamant that nuclear power will be crucial in trying to solve the climate change problem. If we don't use nuclear, then society will be locked into fossil fuels, because we can monitize externalities in our desk studies 'till hell freezes over, but societies are extremely unlikely to monitize them, except in the richest regions where these externalities are likely to draw the needed political support for increasing the cost of energy by 10 ct/kWh.

    To decarbonise the entire system, it is nuclear or bust, because nuclear is cheap and clean, while renewables are merely clean! Budischak's study results confirms this, if anything.

    Now to get back to my original question, which has not been answered. Does SkS agree with James Hansen or not (see the above short video I linked which lays out James' position)? You either agree, or you don't agree, IMHO. I take it you don't agree with Hansen?

     

     

  32. Arctic sea-ice 'growth', a manufactured IPCC 'crisis' and more: David Rose is at it again

    Another article not from David Rose...

     

    http://www.telegraph.co.uk/earth/environment/climatechange/10294082/Global-warming-No-actually-were-cooling-claim-scientists.html

  33. Arctic sea-ice 'growth', a manufactured IPCC 'crisis' and more: David Rose is at it again

    The truly sad thing about all this is that people such as David Rose are fully and consciously aware that they are lying to the public, but that this deliberate misrepresentation of the science works spectacularly well to achieve their goals.

    In Australia the most conspicuous contemporary example of this is the Coalition's intention to repeal the price on carbon pollution.  Every scientist and objective economist understands that a market-based approach is the most effective mechanism for acheiving emissions reduction in a democracy (and even the Coalition's leader Tony Abbott and climate spokesman Greg Hunt understood this up to the time that the carbon "tax" was introduced), but between them the conservative body politic and the conservative media understand that all one has to do to see fruittion of rationally-untenable but desired outcomes is to repeat memes that appeal to the ideological ignorance of a large section of the self-indulgent Western middle class.  It doesn't need to be true - just true in the minds of sufficient people.

    We've long passed the point where simply being right and pointing out that the denialist industry is wrong is sufficient to make the case.  If it was otherwise we'd live in a world where singnificant and tangible changes to emissions were already in train.  David Rose and the rest of the denialist movement well know that they can spout any scientifically-preposterous clap-trap that they like, and all they have to do it to persist in repeating it for the truth to be eroded in the minds of sufficient members of the public that the end result is the same - and that they make a tidy living in the process.

    It took decades to overturn the ideological inertia of the asbestos and the tobacco industries, and even today their acknowledgement of the harm of their products is only effectively manifested in the First World, and even then only incompletely.  The fossil fuel industry is vastly more profitable than either of the former two, however, and the impacts of the fossil fuel industry materialise over centuries and millenia rather than decades, which makes the tangibility of the consequences that much more difficulkt to communicate, so any hope of an eleventh-hour salvaging of even some prospect of effective mitigation will require a much more concerted and substantively different approach to the one that has largely been followed to date.

    As a consequence of a compliant media manifesting the thinking of people such as Rose, and of an ideologically-motivated conservative  government as has just been elected, Australia is putting the cause of carbon emissions reduction behind by decades and the effects will ripple beyond Australia and around the world. 

    Our best last chance is the wording of the upcoming AR5.  If the conclusions from this report cannot galvanise governments around the world to act, then any further reporting by the IPCC or by national scientific bodies will be little more than plotting points on a graph and hand-wringing whimperings of "we told you so".

    I wish that it was otherwise, but I've watched for almost a decade as the David Roses, Anthony Watts, and Christopher Moncktons of the world have been debunked at every turn, time after time, but the effectiveness of their fallacious nonsense continues to maintain the status quo.

    People will believe an easy lie over the hard truth.  And for the last 15 to 20 years lies and deceipt have won at every turn.  As long as this remains the case David Rose and his ilk will continue to publish this type of bilge, and it will continue to have a significant effect to delay action to far beyond the point where the best outcomes can be realised.

  34. 2013 SkS Weekly News Roundup #36B

    Well, the huge fire in SF and another one in Sydney? Wait a moment, it's supposed to be winter down under... Apparently, we alredy have summer here, so no surprise. Fire seasons on both sides of equator, previously disjoint, start to overlap.

  35. Arctic sea-ice 'growth', a manufactured IPCC 'crisis' and more: David Rose is at it again

    Since the heights of summer have passed at my latitude some say that the days have been trending cooler and there are even some people who claim that it is going to get quite cold in the coming months due to something they call "winter".  However, today it is quite a bit warmer than yesterday, so surely this must prove that "winter" is just a hoax.

  36. Arctic sea-ice 'growth', a manufactured IPCC 'crisis' and more: David Rose is at it again

    For those curious about the arithmetical incompetence of the Daily Rail's top investigitive reporter David Ruse, it is worth noting that he does offer his credulous readers two values for the growth of Arctic ice 2012-3. That is 60% and 920,000 sq miles. Thus the areas he has in mind are roughly 2012 = 1,530,000 sq mile (3.9m km^2), 2013 = 2.450,000 sq miles (6.3m km^2). How did he manage to arrive at these values? Would anybody really care? Psychiatrists perhaps?

  37. Arctic sea-ice 'growth', a manufactured IPCC 'crisis' and more: David Rose is at it again

    Yeah - it's incredible. I think the IPCC nonsense is the most blatant bit, but the "growth" meme is the most disingenuous and clearly designed to be repeated by laypersons. Talk about an insult to people's intelligence.

  38. Arctic sea-ice 'growth', a manufactured IPCC 'crisis' and more: David Rose is at it again

    Composer99 and John Hartz,

    Indeed. Rose seems to have even invented/fabricated the rebound number of 60% for his cherry pick! I double checked the numbers (funny Curry ert al. didn't do the same, so much for being true skeptics):

    JAXA extent on 31 August 2012 (km2) : 3.51x106

    JAXA extent on 31 August 2013: 5.05x106

     

    Increase: 44%

     

    NSIDC extent mean August (km2) 2012: 4.71x106

    NSIDC extent mean August 2013: 6.09x106

    Increase: 29%

     

    NSIDC area mean August 2012 (km2): 2.56x106

    NSIDC area mean August 2013: 3.83x106

    Increase: 49.6%

  40. Renewables can't provide baseload power

    JvD - You seem to be presenting a False Dichotomy in your post. Technically, as discussed in the opening post, renewables are capable of baseload power, and are likely to be economical for that in many regions, with Budischak et al 2013 ("Cost-minimized combinations of wind power, solar power and electrochemical storage, powering the grid up to 99.9% of the time") a good example of actually running the numbers. On the other hand, there will be regions such as the UK where land area and energy density limits might make nuclear more economical, a decision dependent on a region by region basis.

    You are demanding an either/or approach, and that (IMO) is an inaccurate representation of the topic. Mitigation and adaptation to climate change are going to require flexibility. 

  41. Arctic sea-ice 'growth', a manufactured IPCC 'crisis' and more: David Rose is at it again

    The following addresses how much the August Arctic sea ice coverage was this year.   

    On Monday, the lead scientist at the NSIDC, based at the University of Colorado in Boulder, blasted the articles on Monday for "playing games" with world opinion.

    "It was very irresponsible reporting on their part," said Ted Scambos, a glaciologist with the ice center. "They know what they're saying and how they are saying it, and to say what they said they had to cherry pick facts."

    Scambos said the Arctic this summer was 2 to 3 degrees cooler than average, and the extent of sea ice in August was a "big increase" for a year-to-year jump. The sea ice was about the size of four Alaskas, at 2.35 million square miles, a 45 percent increase from the same time last year.

  42. Arctic sea-ice 'growth', a manufactured IPCC 'crisis' and more: David Rose is at it again

    Rose then triumphantly states in one year the ice grew by 60%.

    This is so egregious a misrepresentation of the reality that I cannot accurately describe it without being snipped.

    Rose is really scraping the bottom of the barrel here.

  43. Renewables can't provide baseload power

    JvD,

    I see that you are unwilling to write up an article to support your position.  Come back when you are ready to do the hard work.  Instead you criticize others for not doing your work for you.  You would be better off on a site that discusses solutions to AGW (that you have been referred to before) rather than criticizing SkS for not doing something that is not their purpose.

    It is impossible for me to "deny" Hansens position since it is only his opinion and not a consensus position of scientists.  You are being deliberately provocative which is against the comments policy.  Frankly, Hansen is an extreme position on this issue.  The tide of opinion is going against Nuclear.  I was pro nuclear 5 years ago before the recent, multiple disasters.

    It is a waste of SkS space to discuss nuclear further, you have provided no new data to support your position.  Nuclear is not allowed on Real Climate because of people like you.

    Debunking 97% Climate Consensus Denial

    "Lord" Monckton is another unreasonable economist who likes to play the game the way Lomborg does (my earlier comment @21), and he was even able to partcicipate in ruling England for a while.

  45. Renewables can't provide baseload power

    "What is your response to this boots on the ground truth?"

    I take it that you deny Hansen's position. You do this by cherry-picking a single failed nuclear project, which is exactly the kind of wrong approach Hansen talks about in the video. Hansen says that we shouldn't discard nuclear power because of single instances of failure (such as Fukushima), in the same way that we don't discard air travel due to a single airplane crash.

    Did you even watch the video? It's not long.

    Anyway, my response is irrelevant. My question concerns whether SkS accepts or denies Dr. James Hansen's position on nuclear power, renewables and combatting climate change. I've already discussed this issue with you in the past, and you are the kind of environmentalist that James Hansen is particularly concerned about. If you don't mind, I'll your claims for what they are.

    Moderator Response:

    [JMH] You are skating on the thin ice of excessive repetition and sloganeering -- both of which are prohibited by the SkS Comment Policy. Please cease and desist or face the consequences.

  46. Renewables can't provide baseload power

    JvD,

    Perhaps the issue is that no-one wants to volunteer the time to write a paper supporting nuclear power.  You are welcome to write such a paper and submit it to SkS.  I have submitted papers in the past, it is not hard.  Such a paper would undoubtedly get a lot of comments.  It is not the job of other SkS volunteers to support your private opinions.  In general, SkS does not go deeply into solutions, that is left to other venues.

    Hansen has supported nuclear for a long time.  Nuclear requires another $100 billion or more to develop it into a solution for AGW, if it turns out that it can provide the necessary power. India does not seem to be getting very far with their nuclear efforts.  Perhaps if we build a reactor in Syria they will have less troubles, or maybe it will melt down during the war.  On the other hand, new wind is currently cheaper than coal and nuclear and is ready for deployment.  Syria can use wind without risking nuclear holocast.

    In my part of Florida we have the highest rates for electricity in Florida because of failed nulcear power plants.  What is your response to this boots on the ground truth?

  47. Renewables can't provide baseload power

    Has anyone at SKS registered the fact that Dr. James Hansen has been coming out ever more strongly in recent years in support of nuclear power? To be sure, Dr. James Hansen would not agree with the content of this article. At all. According to Hansen, renewables are *not* up to the task. James Hansen is saying very clearly that nuclear power will be necessary in order to combat climate change effectively:

    Is SkS going to be a climate change science platform that keeps distancing itself from James Hansen? It would be nice to see a firm statement by SkS that leaves no doubt, so readers of this website know how to judge the ideology and politics of this website. Either one of the following statements will make it clear for readers what the position of SkS is. Please choose one or suggest a better statement?

    Option 1: "SkS denies that Dr. James Hansen knows what he is talking about, concerning renewables and nuclear power with respect to combatting climate change. SkS confirms that Hansen is utterly mistaken and misinformed about this subject."

    Option 2: "SkS agrees with Dr. James Hansen and will update it's articles to correctly reflect Dr. Hansen's informed position on renewables and nuclear power, in regard to combatting global warming."

    I hope SkS will take the time to clarify it's position in regard to Dr. James Hansen's conclusions on nuclear power, renewables and combatting climate change, clearly for all readers, since this issue is crucial.

    Thank you,

    Joris

  48. Arctic icemelt is a natural cycle

    I'm debating a Watt-bot and he's claiming that Arctic ice decline is all due to changes in wind patterns.  He's posted several articles, but the broadest claims are made here:

    Wind contributing to Arctic sea ice loss, study finds

    Anything in the article that points out this doesn't question climate change's role he describes as spin - even though the study itself only seems to attribute 30-50% of the ice loss to changing wind patterns, according to the article.

    Apparently this line is the dominant response to Arctic ice loss at WUWT other than the occasional rallying cry of "Recovery" (such as we are currently hearing).  Any thoughts on this?

  49. Arctic Sea Ice Hockey Stick: Melt Unprecedented in Last 1,450 years

    Thanks as usual, KR!  

    And Mod, I hate to look a gift-horse in the mouth as it were (this site has already been a God-send to me!), but I think you guys might want to get that changed.  I think it would very positively facilitate continued discussion.  I've made posts to threads that died down several years ago, but if you had that function, people who participated (and are thus interested) would know the thread is active again.  I don't know much about programming, but given it's such a common function of Internet forums, it can't be too difficult.  Just my two cents...

    Moderator Response:

    [DB] The majority of regular users follow the Recent Comments thread, so they will always see any new comments regardless of whatever thread (of the many thousand) they are placed on.  Thus, no thread at SkS is by definition "dead", but many are just temporarily inactive.

  50. Debunking 97% Climate Consensus Denial

    I note that Chris G @17 more than adequately answers Charlie A @12.

    I will note that one of the most damning facts about critics of Cook et al is that they do not employ one of the best, and well known, surveys of the opinions of climate scientists as a counter argument.  Bray and von Storch (2010) explicitly asked a broad range of climate scientists, "How convinced are you that most of recent or near future climate change is, or will be, a result of anthropogenic causes?" (Question 21).  On a scale of 1-7, with 1 being "not at all convinced" and 7 being "very much convinced", 83.51% responded 5 or higher, while only 11.081% responded 3 or less.

    I think this survey question poorly framed.  IMO, somebody who thinks that there is a 5% probability that it will rain today and a 95% probability that it will not is not "a little convinced that it will rain".  Rather, they are mostly convinced that it will not.  Therefore, as the survey question is asked, anybody who responds with a value greater than 1 is at least 50/50 on the proposition, and likely much greater.  Of course, people understand the context of survey questions, and will often treat the middle value as 50/50 even when the logic of the question suggests they should not.  As a result, and as a result of the significant disagreement with other relevant surveys, I consider the poor framing of the question to have biased the result low.

    I must recognize, however, that the 83.5% is a defensible position.  Somebody arguing that Cook et al over represents the "consensus" in that Bray and von Storch show the consensus of actual scientists (as opposed to papers) to be 83.5% has an arguable case.  Despite this, the fake "skeptics" do not argue this case for it would require admiting an 83.5% agreement the claim that most recent or near future warming was or will be the result of anthropogenic factors.  Worse, it requires recognizing that only 1.351% of climate scientists are certain that this is wrong.

    Even more troubling for the fake "skeptics", however, is that 78.92% of climate scientists are significantly convinced (>4 reponse) that "...climate change poses a very serious and dangerous threat to humanity" (question 22).  "Humanity" is vague as to whether the threat is merely to very large numbers (hundreds of millions, or billions) of humans, or whether it is a species level threat, ie, a threat of extinction.

    It is a difficult task you set yourself when you attempt to obfusticate and confuse the public on climate science.  You must thow over even reasonable arguments that appear to support your position, for using them will let too many facts out of the bag and loose you any thoughtful people.
