    1. Mann providing access to his data is irrelevant. Everyone is free to gather the same data themselves. In fact, if one were truly afraid of some wort of bias by Mann's data gathering, then that is the only responsible thing to do.

    In all honesty, it's not terribly surprising that both Mann and McIntyre failed to get their statistics correct. Neither are statisticians, and in all honesty, a lot of the mathematical analysis by non-mathemticians are just plug and chug with some technique that's been passed down and explained cargo-cult style.

    McIntyre's paper (23 pages)

    It comes down to that the thought that Mann in 1998 got his math wrong when performing principle component analysis over the data, particularly while using Bristlecone Pine cores. (Which I have to say is an amazing organism. They live at least 5,000 years. Wow. Just wow.) The 2008 Mann paper does two different analyses, one with tree cores, and without. The hockey stick remains in both.

    Mann should have given McIntyre the data, which he started to do, but then stopped for some reason. Why, I don't know. I suspect there was some personality clash, but that's just speculation on my part. Just release the data. Who cares? If someone wants to examine the samples directly, then let them if they real credentials (i.e. a PhD in climatetology or some other related field). It's just impractical to give access to every Joe down at the bar, samples can be damaged. It's a scientific resource worth millions, not an exhibit at a hands-on museum.

    The conclusions of all the investigations was that Mann didn't do PCA right, like how McIntyre said, but McIntyre didn't do it right either.

    Perhaps the most interesting for you would be this link than contains links to the Mann's data, and statistics source code to analyze the data correctly. You just have to download R.

    Sorry about that.

    The original MBH98 "Hockey Stick Paper" is "Global-scale temperature patterns and climate forcing over the past six centuries" by Michael E. Mann, Raymond S. Bradley & Malcolm K. Hughes from Nature 392, 779-787 (23 April 1998) | doi:10.1038/33859

    The latest work, correcting for the concerns brought up in 2003 is "Proxy-based reconstructions of hemispheric and global surface temperature variations over the past two millennia" (Mann et al. Proceedings of the National Academy of Science. USA 105, pgs 13252–13257; 2008)

    PNAS is open access, and the Nature article linked to in this comment comes from Mann's homepage, so you should be able to read them both. My original link to MBH98 was to Nature's site, and they want you to pay $32 to read the article if you don't already have a license.

    The only question is why did he choose the words "hide" as opposed to "correct" and "decline" as opposed to "error" which the skeptics (of this breach) are trying to imply, that "hide the decline" has the same meaning as "correct the error". I would argue to everyone, that the word hide implies falsification or concealment. So the author was knowingly manipulatin data to conceal the truth. Where the truth is some statistic that indicates there has been a lowering of the trend.

    Oh please. Like in your private emails and informal talks with your colleagues are super precise with your words. Next you'll be telling me that when you said, "Jim fucked the code," you literally meant that Jim printed up the code, drilled a whole in the middle of the stack papers, and proceeded to penetrate it with his penis, or that when you said that "the server blew up," you literally meant that the computer experienced a Baysplosion.

    Why didn't he use "error" instead of "decline?" Easy. He knows what the error is. The error goes down ("declines").

    Since you didn't bother to do any research before tossing around allegations of lying, nor bothering to figure out what exactly "Mike's Nature trick" actually was, let me.

    A quick google search of "michael nature global temperature" points to : "Global-scale temperature patterns and climate forcing over the past six centuries" by Michael E. Mann, Raymond S. Bradley & Malcolm K. Hughes from Nature 392, 779-787 (23 April 1998) | doi:10.1038/33859

    This was a a seminal article in the climatetology community. Mann et al took tree core samples and estimated the global temperature by measuring the spacing between tree rings. (Big rings are caused by rapid growth, which is in turn caused by warmer temperatures. Small rings, slow growth, cooler temperatures.) The fact that tree ring sizes are dependent on temperature has been a long established fact.

    Let me now quote the abstract of this article in full:

    Spatially resolved global reconstructions of annual surface temperature patterns over the past six centuries are based on the multivariate calibration of widely distributed high-resolution proxy climate indicators. Time-dependent correlations of the reconstructions with time-series records representing changes in greenhouse-gas concentrations, solar irradiance, and volcanic aerosols suggest that each of these factors has contributed to the climate variability of the past 400 years, with greenhouse gases emerging as the dominant forcing during the twentieth century. Northern Hemisphere mean annual temperatures for three of the past eight years are warmer than any other year since (at least) ad 1400.

    Mann et al tried to create an accurate record of the global temperature by augmenting the estimated temperatures from the tree ring data with actual measured temperatures from 1981 and 1961 since these are actual known temperatures. This is known as "the MBH98 reconstruction".

    Now hang on. Here's where your allegation of "systematic suppression of data" falls all apart.

    In 2003, Stephen McIntyre and Ross McKitrick published (*gasp*) Corrections to the Mann et. al. (1998) Proxy Data Base and Northern Hemispheric Average Temperature Series, whose abstract reads:

    The data set of proxies of past climate used in Mann, Bradley and Hughes (1998, "MBH98" hereafter) for the estimation of temperatures from 1400 to 1980 contains collation errors, unjustifiable truncation or extrapolation of source data, obsolete data, geographical location errors, incorrect calculation of principal components and other quality control defects. We detail these errors and defects. We then apply MBH98 methodology to the construction of a Northern Hemisphere average temperature index for the 1400-1980 period, using corrected and updated source data. The major finding is that the values in the early 15th century exceed any values in the 20th century. The particular "hockey stick" shape derived in the MBH98 proxy construction – a temperature index that decreases slightly between the early 15th century and early 20th century and then increases dramatically up to 1980 — is primarily an artefact of poor data handling, obsolete data and incorrect calculation of principal components.

    So the worldwide conspiracy of climatetologists breaks down when they behave like scientists, and try to duplicate each others' work, fail to, and publish corrections, and warnings saying, "Hey! You this data set we've all been using? It might be wrong."

    Thus begins The Hockey Stick Controversy, named after the shape of the curve at the very end of MBH98 reconstruction. Far from being suppressed, it's investigated quite thoroughly

    I agree that there's no need for new regulations, except to transition the power grid en masse, but since the utilities have been wanting this for a while now, it certainly seems like this sort of transition would move naturally. The only thing would need to be worked out would be technical details, but those are easily taken care of.

    I disagree that there wouldn't need to be investment. The current meters don't have anyway of knowing what the current price is. There would need to be someway of sending that information to the customers.

    I have a feeling that it will happen. Just no time soon. After all, HDTV finally got deployed after what? 15 years? There's money involved with a smart grid. The real question is if the US will get a smart grid early or late.

    It's not a large amount of data. It's just the current demand at that instance. In order for customers to be able to regulate (i.e. shift) demand, they need to know when the power was needed and what price it was charged. Simply saying "You owe us $x," doesn't really give you enough information to shift demand effectively. Receiving a simple total, like you proposed, is exactly what we have now.

    The smart grid off peak scheduling tricks have always relied on customer controlled technology. The idea was always to have the real smarts being in every appliance in the home. The smart meter would inform the appliances what the current price of electricity was, and your refrigerator would decide whether or not to cycle for a particular hour based on that information.

    Even the big bad profiling of the different appliances would be useful. I'd like to know that my refrigerator or air conditioner is costing me $x, and that if I upgraded to a smarter and more efficient model, my costs would go down to $y. Right now it's guess work.

    Well yes. And it's perfectly fine to be uncomfortable with it. Fox has long been known to be biased from both left and right (e.g. Jonah Goldberg). Is it awkward and troubling for a media outlet to be singled out from an administration? Sure. At the same time though, it's not exactly that FoxNews has been on the up and up. It never was.

    If there's a genuine medical need for special equipment like a larger monitor then of course it's good practice to provide that where it's economically viable to do so.

    "Good practice" and "economic viability" don't enter into the equation. It's the law. As it should be. You can't simply say "Well that costs money, so no." That's unlawful discrimination. Now not everything can or needs to be accommodated, but easily rectifiable things must. Even if you think that it's "too expensive," it's the employer's responsibility to search out equally effective, less costly options, and "must also consider whether funding for an accommodation is available from an outside source, such as a vocational rehabilitation agency, and if the cost of providing the accommodation can be offset by state or federal tax credits or deductions. You must also give the applicant or employee with a disability the opportunity to provide the accommodation or pay for the portion of the accommodation that constitutes an undue hardship."

    But that's after they've sought medical advice and can support a need for special treatement.
