    2012 SkS Weekly Digest #12
    Number of items: I would prefer more in-depth, but less in number, if only due to time restraints. Yes, I read all articles and most comment threads, except when two people are battling it out and it is clear that neither will give way. Having said that, I rarely go back over the comment threads once I have read them, unless there is an unresolved issue that I am interested in that might be resolved in later comments. I post when the mood takes me, but usually only once per article.
    Moderator Response: [JH] Thank you for the feedback and for being a regular reader. Your active particpation in the comment threads is also appreciated.

    More evidence that manmade climate change has been impacting the global climate system: “The past decade has been one of unprecedented weather extremes. Scientists of the Potsdam Institute for Climate Impact Research (PIK) in Germany argue that the high incidence of extremes is not merely accidental. From the many single events a pattern emerges. At least for extreme rainfall and heat waves the link with human-caused global warming is clear, the scientists show in a new analysis of scientific evidence in the journal Nature Climate Change. Less clear is the link between warming and storms, despite the observed increase in the intensity of hurricanes.” Source:”Weather records due to climate change: a game with loaded dice,” press release posted by the Potsdam Institute for Climatic Impact Research on March 25, 2012. To access the entire press release, click here. Note: The entire press release will soon be posted verbatim on SkS.

    Better than that would be a shortened url rather than the long ones woodfortrees does.
  5. An Open Letter to the Future
    william@28 Coincidentally I was thinking about this subject this very morning. Clay tablets are cumbersome and fragile. Stamping the words into thin metal sheets (like giant dog tags) and stuck in binders would be more durable. This has risks of its own. In the post pox-eclipse world the person who finds such a book might destroy it to use the metal. Not the kinds of future I want for my kids and (potential future) grand kids.
  6. The Skeptical Science temperature trend calculator
    Very useful. Thanks. A nice-to-have would be the ability to create a hyperlink to a specific graph (like woodfortrees offers). D.
  7. An Open Letter to the Future
    ScientificSkeptic@25 We are not "being asked to gamble our lifestyles on a woolly prediction" we are, rather, obligated to make policy decisions based on the best science we have. Business-as-usual is a choice, too. As for "cut to the bone", well, I would like to hear why you think that proposals to make users of fossil fuel energy pay now, for the consequences of their putting CO2 into the atmosphere, will be all that costly. Prominent economists like William Nordhaus don't think so. See here also. I hope that you are correct about the higher quality of life in 5000AD. You are certainly correct to say that humans have a great capacity for adaptation that will continue--we'll quickly adapt to a carbon tax, too--but one thing that sets us apart from other animals is our ability, limited and imperfect though it is, to see the future. Here's hoping that we use that ability wisely. That's what Kate's article was about.
  8. An Open Letter to the Future
    Arguments like "Earth will be fine" and "humans won't go extinct" really bother me. Personally I'd like to set the bar a little higher for our species than 'not going extinct'.
  9. An Open Letter to the Future
    SciSkep#25: "I think the threat from AGW is rather exagetated " And this opinion is based on ... ? For a counter opinion, based on actual research, see Trenberth's latest: The average anthropogenic climate change effect is not negligible, but nor is it large, although a small shift in the mean can lead to very large percentage changes in extremes. ... It is when natural variability and climate change develop in the same direction that records get broken. Perhaps you will ask: What records get broken? Heat, drought, fire, flood, famine... Exaggerations, not.
  10. An Open Letter to the Future
    Perhaps it is time we put the record of our times on clay tablets, fired them and concealed them all over the world. Our paper won't survive and likewise our floppies, stiffies, DVD's and flash drives. Perhaps the best thing we could do for these people of the future is to record the greed of our bankers and CEO's and the role vested interests played in our society. Dark ages have happened repeatedly in the past but this time it will involve the whole world. Perhaps we can keep the next organized society that rises from the ashes from making the same mistakes. We aren't having much success with this one.

  12. Catching up with the Younger Dryas: do mass-extinctions always need impacts?
    It is a fine example of science in progress, with actual skepticism applied. Huge difference between that and "I don't like this so I'm not gonna listen!" It's interesting to note how some activists who oppose a lot of climate science are moving towards acceptance of the century-old physics behind the greenhouse effect and the notion that rising greenhouse gases will cause warming: yes there is a debate WRT overall sensitivity including feedbacks both in the literature and in the blogosphere, but even so, to me the bottom line is how big a risk are we prepared to take?
  13. Medieval Warm Period was warmer
    If it has unknown driver, then why do we see something like MCA in forcing-based models? (See the AR4 discussion). That is not to say that there is a strong consensus of mechanisms, especially for the regional distribution, but its not a great mystery.
  14. Catching up with the Younger Dryas: do mass-extinctions always need impacts?
    J Mason- Thank you for a very interesting post. When reading about the various research articles on the pro and con side of the impact theory I could not help but think - now this is how science really works (as opposed to the political back and forth plaguing the AGW "debate"). This would make a fascinating module for a high school or college earth science class, to expose kids and young adults to how critical thinking plays out in the world of science. Especially since it is playing out in real time. Though the latest evidence appears to be tilting in favor of an impact hypothesis the questions raised by the follow up papers on the Murray Springs site (regarding such things as background iridium levels)appear to have been the true kind of skepticism, well informed and asking reasonable questions. Having been a geology student during the time when many of the details of plate tectonics were being fleshed out I know form experience that very good scientists asking very good questions can later be perceived as having been on the "wrong" side of some of the issues being explored, which I think is unfortunate. As long as the questions are asked in the true spirit of scientific inquiry (ie you have to accept data that goes against your ideas and rework your hypothesis appropriately)there is no such thing as being on the wrong side in a scientific debate. That's why it's so sad to see such an important and fascinating topic as climate change subjected to the political hucksterism and deliberate disinformation that we have so commonly seen in recent years.
  15. An Open Letter to the Future
    Hi Dikran, As you know, AGW is real (not a prediction) and it is happening now (again not a prediction) and it is already having costly impacts (e.g. Coumou and Rahmstorf 2012, Nature), both in terms of lives lost and fiscal losses. Yet, despite this overwhelming evidence that a global disaster is in progress, some continue to deny that we have a serious problem on our hands (e.g., the poster at #23 and #25).
  16. An Open Letter to the Future
    25, ScientificSkeptic, You have it backwards. You are being asked to gamble your comfort and lifestyle in about 20 years, and that of your children and grandchildren and all their descendants, against your "thought" that "the threat from AGW is rather exaggerated" (an opinion not shared by scientists, the people who actually know) and the unfounded fear that taking action is somehow going to "gamble our lifestyles." Mitigation now is not nearly that expensive or that bad. The Inhofe's and the Monckton's of the world want you to think so, but taking adequate action now is not going to cause suffering. Failing to take action that is required anyway due to increasing energy demands and falling fossil fuel resources, so that the people who hold those resources can make maximal profits before everything comes crashing down, that's the "gamble" of "our lifestyles." I suggest you use this site to learn more about the facts of the issue. Stop looking for the Hollywood extremes and pay attention to what the science really says.

    Peter Hadfield Letter to Chris Monckton
    Dana... Anthony's issue was with the interview Hadfield did with Sinclair. There is no transcript of that. In fact, I just got an email from Anthony rejecting my offer to transcribe the interview for him.
  18. Peter Hadfield Letter to Chris Monckton
    re 41- and my apologies to those magicians who can pull a real rabbit out of a real hat.
  19. Peter Hadfield Letter to Chris Monckton
    Hadfield provided a transcript - it's also provided in the above post, below the introduction, before the video.
  20. Peter Hadfield Letter to Chris Monckton
    I have been wondering if Monckton, when he gets back to his hotel room after the applause has died down, feels even slightly embarrassed by the quality of the audience he attracts. For some reason, it made me think of a professional magician who will not show his tricks at a magician's conference, but has to find an audience that is still amazed that he can pull a rabbit out of a hat.

    An Open Letter to the Future
    ScientificSkeptic I don't think AGW will be the end of us as a species either. However I rather doubt that many people will think that is a good reason not to worry about it. I think it will almost certainly be the end of many human beings, whos life is worth exactly the same as yours or mine. I think it is also likely to cause a lot of hardship and misery in many parts of the world that don't have the resources to adapt to change as easily as we could. Most codes of behaviour are quite familiar with the concept of the "golden rule", i.e. treat others as you would wish them to treat you. I very much hope this will still be an important foundation of societies in 3000 years time. If not we will undoubtedly have regressed.

  23. Skeptical Science hacked, private user details publicly posted online
    Ha, I guess this sucks, but at the same time, my response is "Oh no, people will know I care about climate change!~" In the next few decades and beyond, I highly doubt this will be problematic for me. "Shoot, people know I care about the well-being of future generations."

  25. 2012 SkS Weekly Digest #12

    This may be slightly off-topic, but i have a question triggered by the Toon of the week... This is a Weather question (but with a climate underpinning). Currently, the UK is experiencing an unseasonal heatwave. The proximate cause is a jetstream blocking event, so we are under perpetual high pressure. I note ( from NSIDC that Arctic Sea Ice extent is relatively high (compared to the last few years only!). Is this a flipside of the same jetstream cause?

    Moderator Response:

    [DB] If you look at the areas where the ice is concentrated, you'll note that much of the recent gains in ice cover are in those areas about to melt out abruptly in the next 6 weeks:  The Sea of Okhotsk, the Bering Sea, the Kara Sea, portions of the Barents Sea, Baffin Bay and Hudson Bay.

    Get your popcorn ready, the show is about to begin (best watched from here).  Relevant discussion is here, as well.

    As for the other part of your question, Real Climate has a post up on this here and Dr. Kevin Trenberth also has a paper out on much the same topic here.

    [Sph] Personally, I think the best show is here (only in the 21st century)

    I'm with adelady - quality is more important than quantity. If you can increase quantity without sacrificing quality then go for it. I read all posts and all comments that are there at the time I read the posts - and sometimes go back to see if any one has added a useful comment. I occasionally comment.

  28. The Skeptical Science temperature trend calculator
    A very nice tool, thanks. Great work on putting that together. It's useful to see the uncertainty bounds for the different datasets over different time periods.
  29. The Skeptical Science temperature trend calculator
    Kevin, it looks great, and it all worked for me. And thanks for the kind words. I found a discussion here (near the end) of how to convert a canvas image to a PNG file.
  30. The Skeptical Science temperature trend calculator
    OPatrick: Thanks! It didn't occur to me check browser compatibility of save-as. This feature depends on the browser providing a tool to turn an HTML5 canvas into a virtual image. A quick check now shows that it works in Firefox 3.6 but not in google Chrome 17. If it doesn't work in your browser, I'm afraid you'll have to fall back on using a screenshot tool.
  31. The Skeptical Science temperature trend calculator
    This looks really cool; I may or may not want to play with it a little later. I may not because I'm already disheartened by this bit of news about "...global-mean temperature increases of 1.4–3 K by 2050, relative to 1961–1990, under a mid-range forcing scenario...". Man I hope they are way off; relative to _1961-90_ and _mid-range_ forcing caught my eye. I know, a bit OT; only thinly connected.
  32. The Skeptical Science temperature trend calculator
    A great tool, thank you. At first impressions very user friendly and clearly explained here. One possible problem, though it might just be me - you say "To save a graph, use right-click/save-image-as." However this doesn't work for me, it's not recognising it as a separate image. I can select the section and copy it, but this doesn't give me the scale or axis labels.

    Daniel #39: Watts is indeed hearing-impaired. He even used that as a defense when he made false claims about the initial BEST analysis.
  34. Daniel J. Andrews at 16:18 PM on 26 March 2012
    Peter Hadfield Letter to Chris Monckton
    Watts says "While I can’t hear what Hadfield is saying (he sounds like a British mumble to me)" And it is because of people like Watts that they replace Sir David Attenborough's distinctive clear voice with American actors thereby taking a superb documentary and turning it into just another bunch of pretty pictures with nothing to distinguish it from other nature films. I saw 30 seconds of Frozen Planet while visiting friends and it had Baldwin narrating--it was turned off quite quickly. Without saying anything to each other we all agreed it was much better to wait for it to air in Canada as they'd keep Attenborough's voice in it. On some consideration, I wonder if Anthony needs a hearing aid?? My dad started complaining that people with accents mumble (he's British so pretty much everyone he met in Canada was "mumbling"), but once we talked him into getting hearing aids--only took five years--he could understand people quite well again. Peter H certainly doesn't mumble. He enunciates quite well and is easily understandable.
    Moderator Response: [RH] Anthony Watts does have a hearing impairment which would cause this video to likely be somewhat unintelligible for him. I sent him a private email (cc'ing both Peters) saying I would take the time to transcribe the video for him. I have not heard back from him. It's one thing to not be able to hear it, but it's quite another to not want to and to come to conclusions about what is being said without actually knowing what is being said.
  35. Medieval Warm Period was warmer
    markx @ 119: "Whether it was precisely co-incidental is perhaps not of great importance" Actually, I think it is of great importance. If there were warm periods, but they were at different times in different locations, then that is merely evidence that the earth's climate is somewhat variable. On the other hand, right now, it's warmer everywhere at the same, which seems to be unprecedented for at least the past six or seven thousand years. When it comes down to it, though, it's not just about whether the climate was warmer / cooler in the past. It's about what caused those warmer / cooler periods. And right now, there's only one explanation that stands up to scrutiny for the current warming (hint: it doesn't involve the word 'natural').

    Peter Hadfield deserves a medal for holding Monckton accountable for his nonsense. Peter's efforts have placed Monckton (and those who aid and abet Monckton's fallaccies and misinformation) between a rock and a hard place :) A very sincere thank you Peter!
  38. Medieval Warm Period was warmer
    Tom Curtis at 13:17 PM on 9 February, 2012 ".....the implicit claim that the MWP was globally warmer than the last two decades for the entire period of the MWP is refuted by the same comparison..." Tom, I'm not sure that IS the claim. The argument is that there exists in various worldwide proxy records some evidence that there was an unknown driver of a temperature elevation which was evident globally within a certain time bracket.(and referred to as The Medieval Warming Period). Whether it was precisely co-incidental is perhaps not of great importance, should a spate of extreme high temperatures such as that be observed today, surely we would label it as evidence of "Global Warming"?
  39. 2012 SkS Weekly Digest #12
    I'm in two minds about the # of articles. I'll just say that I'd prefer SkS prioritised quality over quantity. I try to read every article on SkS. This can be difficult to squeeze around other commitments at times, but it's always worth it. I've learned a phenomenal amount about climate science since finding this site. Comments I sometimes read, sometimes not (depending on available time & whether that particular topic interests me). I post comments when I feel I have something to contribute. And I must say, it's easy to do so here on SkS, because I know that if I get something wrong, the inevitable correction will be a gentle one. :-D

    Barry - speak in code, man! Doug H - that's the obvious difference between the denial-o-sphere and the science. It's all open here. When the professional doubters get cranked up and try to push untruth onto the open side of the ledger, we get Scafetta, Michaels, Lindzen, Spencer, and the usual second-tier oddballs publishing mathturbation at WUWT. This hacking is a milestone for SkS. The range of possibilities is limited: private conversations twisted out of context, a chilling effect (fat f-ing chance), or the possibility of finding something juicy that 99% of the posters here know nothing about. John Cook, you are actually the clone of Friedrich Engels. Gasp! Or perhaps this is some sort of bizarre "payback" for Gleick's action. This is either childish (I know a number of net technicians who have a slim grasp on adulthood, despite their thinning hair), desperate, or just another move in the "yes, my integrity is for sale" game of opinion-making and economic manipulation (probably a combination of all three in different parts of the action). It reminds me of putting someone in a bad position on the chessboard and having their response be "accidentally" tipping the board over.

    Peter Hadfield Letter to Chris Monckton
    Look 16% of the population is rational and analytical by birth For the rest of the population, it is an ill-fitting suit. So roughly half of the non-rational are going to get it right, and half won't - maybe 75% of the rational will get it right (GIGO). so right now it appears we are losing. But CA and BC and Australia and most of Europe are already preventing climate change. We are due for one wallop of an El Nino - polling data tells us people "believe" in climate change more as it gets warmer each summer. So a particularly hot summer could turn this whole thing around, and these ignorant-on-purpose folks will find something else to be silly about. We just need that hot outlier soon, ideally in a US election year....

    I reckon the number of items published is pretty good. Yes. I read every post and every comment. There are some I might skim over, though. I do take more time with particular topics that interest me. Commenting? Not being a scientist or a statistician or any other useful occupation, I'm more interested in what some of the really knowledgeable commenters have to contribute. I limit my own comments accordingly.

    • From your perspective, does SkS publish too many, just the right amount of, or too few, articles per week? I read as much as I can find on the topic, here and elsewhere. More would be welcome.
    • Do you typically read each article that is posted? Yes
    • Do you typically read the comment threads? Yes
    • Do you typically post comments? Not often, as I am not a scientist, so have little to add to that side of discussions. I do post when I think I have something relevant to say

    Peter Hadfield Letter to Chris Monckton
    I met my first honest-to-God conspiracy theorist on Saturday, while handing out 'How to vote' cards for our State (Queensland) election. He genuinely believes that 9/11 was a USA conspiracy and that there is a small group ruling the world, amongst a raft of other ideas. I didn't engage him on AGW, not surprisingly. Up until then in my life, I have been treating everyone as reachable and teachable. Not any more. I now know there are genuine conspiracy theorists, who sincerely believe propositions that I regard as completely insane. For that reason, my attitude toward the Mighty Monckton has mellowed a little. Previously, I regarded him as an intelligent person who is deliberately spreading misinformation for reasons of his own. Now, I have to admit there is a possibility that he is like my voter: a simple soul who genuinely believes what the voices in his head are telling him. If so, it would explain his religious zeal in spreading the Word to the masses.

    John, I have solved all the problems you are dealing with many times before on the social networking sites that I run, and would to help you with my experience and tools. This testimonial on my linkedin page is quite apposite: "Andy is a multi-talented iconoclast. He's exactly the guy you want on your team when Russian hackers decide to take down your server. However, don't be surprised if you discover him playing piano late one night (or early in the morning) at your local watering hole. I'm 100% certain that Andy has capabilities that I haven't even considered. What I do know is that he is honest, loyal and hard working - the right kind of guy to have in your corner."

    FWIW, Over at Hot Topic this issue arose, and a regular poster (from the other side - one who has considerable expertise in this area, however) has downloaded the zip file and tells me the following:
    The user.csv file contains usernames, date of joining, user level (an integer 1-14 or so) and email addresses The email addresses are not really redacted as such. They seem to drop the last part of the domain (e.g) .com) Example would be joe@gmail,so therefore it is pretty easy to deduce the full email address in most cases. There are no IP addresses in the user csv, but I have since noticed that IP addresses are logged against user names in the forums (these are the “private” forums where mods and other power users are discussing SkS strategies etc). There are no passwords from what I can see. John Cook posted on SkS that passwords are encrypted on his website, so a hacker would have to get hold of the encryption key.
    (Or crack them via the method andylee discussed above, I suppose, but it's really hard to see any great benefit being derived from this.) Anyway, he echoed Gareth's statement, as reiterated above, that it would be prudent to change any passwords, especially if you share your SkS password with any other websites. I've certainly not noticed any influx of spam or hatemail, thankfully!
