    Why is all the blame heaped on Snowden?

    Because he is the one that arrogantly ignored the democratic process, stole a massive store of intelligence documents, incompetently encrypted them, and made them available for friend and foe alike, and then fled to be among Americas adversaries.

    I was unaware that the activities of the NSA were carried out under the auspices of the "democratic process". We live in a representative democracy. When someone like Bruce Schneier (who has access to the Snowden documents) can meet with legislators (that is, the people who are supposed to be our representatives in this democracy) and tell them what our government is doing rather than the other way around, I think it can be argued that the activities of the NSA no longer constitute part of a democratic process but rather, an arrogant ignoring of the democratic process (as you put it).

    Bullshit. If I have a glass half full of boiling water, and a glass half full of ice water, the two glasses have an average temperature of around 50 degrees C. If I pour one into the other, the hot water will cool, and the ice water will warm; but the average temperature is still 50 degrees.
    The heat was redistributed, but the average temperature hasn't changed.

    No, in your example the average temperature will drop but the total heat of the system will remain the same.

    In the commonly understood meaning of ice water, you will have a mixture of ice and water. Such a mixture is understood to have a temperature of 0 degrees centigrade but additional heat needs to be lost to make the transition from liquid water at 0 degrees C to solid water at 0 degrees C (heat of fusion). The mixture of your water at the boiling point and your ice water will equilibrate at a temperature below 50 degrees C. The actual temperature will depend the percentage of water that is in the form of ice in the ice water.

    So if the heat can go somewhere other than to change the temperature of water you can have changes of the mean temperature of the water.

    Likewise in the rest of the comment, a global energy balance surplus need not mean a short term global surface temperature increase and an energy balance deficit need not mean a short term surface temperature decrease because the energy balance affects more than air temperatures. The oceans, in fact, act as a massive heat sink (and the data is there showing that surplus heat is going there). That is, additional heat affects more than surface air temperatures, it affects ocean temperatures. As a result, anything which affects the heat balance into this heat sink will affect air temperatures. This means that a heat surplus can be masked if additional heat gets temporarily dumped into the ocean but it also means that if the process that is dumping surplus heat into the ocean decreases you will see an atmospheric temperature rise.

  7. Re:Did it "confirm" it was caused by man? on Global Warming 'Confirmed' By Independent Study · · Score: 5, Informative

    It was probably caused by man.

    By measuring temperatures in dumb-ass places, the BBC link in the article sums it up nicely with a picture of a weather station next to an airplane, and you could argue that jet exhaust and black tarmacs are natural, but you can't argue that jet exhaust and black tarmacs are representative for the earth surface in average.

    Actually, the heat island effect was one of the things that this study was meant to address. The climate skeptic's contentions on this are basically threefold:
    - Urban heat islands exist and they are warmer than they otherwise would be if urbanization had not happened (I don't think anyone disputes this).
    - Urban heat islands exaggerate warming trends.
    - Unlike TV weathermen, climate scientists are too stupid to realize that urban heat island effects could affect their data and too stupid to correct the data for it (even though it is quite likely that clever TV weathermen probably read about this effect in the climate science literature in the first place).

    What this group has found on the matter, to their great surprise, is that not only doesn't the urban heat island effect not exaggerate warming trends, it actually dampens them a little bit. In other words, if you are not accounting for the urban heat island effect it makes the hockey stick less steep, rather than more steep.

    Which is no great surprise to me because others have already looked at this due to the stink Anthony Watts was raising and found the same thing (though I would guess Watts probably doesn't talk about that too much).

    Note the huge uptick in average temperature starting roughly 11.5k years BP.

    That's not a very reassuring comparison if you want to calm down the alarmists. You know what else happened at a time when, despite what you are suggesting, temperature change was slower than what we seem to be getting now, at ~11.5k years BP? Yup, that's right, a mass extinction.

    Wait a moment, folk! We are talking about temporary separation of already uncoiled DNA (meaning, that it's probably under the process of being expressed, anyway) under very specific conditions as predicted by a computer model.

    This is not even an empirical observation: we don't know that any of this happens in a cell free in vitro system and how significant the effect is (if any), we don't know if it happens in a cell culture in vitro system and how significant the effect is (if any) and we certainly don't know that anything like this happens in vivo.

    Even assuming that you can create these precise conditions by an airport scanner (which seems rather doubtful), you certainly would not, in any way, be facilitating mutation in any appreciable sense*. All that you would be doing, theoretically, is to subtly alter patterns of gene expression for the few seconds it would take to walk through the scanner (basically, a very subtle regulatory effect). While you certainly can facilitate the development of cancer through such a mechanism (in fact, I'd argue that dysregulation of gene expression** at some points is simply required for carcinogenesis --yes, it can be caused by mutating proteins but these mutated proteins are almost invariably going to have direct or indirect regulatory functions***), such a dysregulation of gene expression would have be the prolonged, normal state of affairs of a cell for a cancer to actually happen. For this to be happening (in a worse case scenario) for as much as a few mere seconds can hardly even be called a dysregulation in any meaningful sense and much, much less have any effect, whatsoever, on carcinogenesis.

    If, on the other hand, some government agency is monitoring you 24/7 with these scanners, then you might have reason to worry****.

    * I would speculate that there's an infinitesimal chance that DNA might be more susceptible to mutations from not being as protected as it would be when paired but you have to realize that active regions of DNA get unzipped like this all the time so this effect, if it might be real, would be a drop in the bucket and utterly swamped by the background.
    ** For purposes of this discussion, what I mean by dysregulation of gene expression is the production of various protein products at inappropriate times or in the wrong amounts (either too much or too little of a protein).
    *** Whether the function is to induce cell division or stop cell division, or to induce cell death (apoptosis) or to evade cell death (and whether it is a direct or indirect effect on the preceding --such as mechanisms sensing DNA damage, loss of contact inhibition, etc.). While other factors which may not always be strictly regulatory do exist such as invasiveness, angiogenesis, telomerase function, etc (which often will also be regulatory by involving over or under expression); these factors need to happen together with a regulatory dysfunction for an actual cancer to happen because, basically, cancer happens when a lot of different sorts of things get screwed up at the same time.

    Dogs can detect molecules on the order of a couple parts per million, far below our level of detection. They can also smell cancer, and can tell the difference between different kinds of internal cancer just by smelling the skin. They have also been shown to be able to predict seizures, and hypoglycemic attacks.

    Since when is a couple of parts per million below our level of detection? Anyway, at the "concentrations" at which homeopaths consider potency to be greatest (in other words, the most dilute concentrations) it's not so much a matter of the solute existing at infinitesimal concentrations as much as there being not solute molecules left whatsoever.

    Not even homeopaths dispute this. Instead of this they make some up bullshit, ad hoc stuff up about vibrations being left behind in the to form a memory of what used to be there.

    And I really have no clue as to why you are bringing dogs into it. That's an altogether different discussion.

    Just because we cannot detect low levels, doesn't mean they are not there nor have any effect.

    That's pretty much an oxymoron since any effect constitutes something we can detect.

    However you seem to be misunderstanding why there might not be something in there at all in some homeopathic preparations. It has nothing to do with whether we can detect it or not. It has to do with atomic theory, a concept which has been with us in its crudest forms for at least two millennia and which modern science has confirmed. You see, stuff is made up of discrete chunks. Let's say you've got a volume of water with 10000 arsenic cations (that's a kind of chunk). If you dilute it ten fold you will only have, on average, 1000 arsenic cations in that same volume of water. If you dilute it a million fold, you will have on average zero arsenic cations in that volume simply because there were a lot fewer than 1000000 arsenic cations to begin with.

    How does this relate to homeopathic preparations? The most dilute homeopathic preparations out there (in other words, the ones which homeopaths consider the most potent --ever hear the joke about the patient who forgot to take his homeopathic medicine and died of an overdose?) are prepared at 200C (sometimes also written as 200 CK depending on which nutty dilution protocol is used: that of Hahneman or that of Korsakov). What this means is that the original substance is diluted one hundred fold and then the resulting solution is diluted one hundred fold again another 199 times. That means the dilution factor is 100^^200. This is a 1 with 400 zeroes after it. Not only is this number much greater than the number which is a homophone to the name of a popular search engine, it is also greater than the estimated number of atoms in the whole universe (which http://preview.tinyurl.com/nypp6pWikipedia estimates to be a lot fewer than a googol).

    What this means is that if you put the same number of solute molecules as there exists atoms in the universe into a container and performed a 200C dilution you would end up with no solute molecules by the time that you were done with your serial dilutions.

    So basically, paraphrasing you, to say that "just because a homeopathic preparation is diluted beyond Avogadro's limit doesn't mean that it does not have any effect" is like saying that "just because distilled water doesn't have any salt in it it doesn't mean that it is not going to taste salty".
