  1. Re:The LHC should be destroyed on LHC Success! · · Score: 1

    Hawking radiation is thought to be emitted by all black holes. They will slowly evaporate by this process if nothing adds mass to them (such as infalling matter and radiation). The pairs-of-virtual-particles description is a loose description of the mechanism by which it happens. Smaller black holes emit Hawking radiation at a greater rate.

    Yes, they measure carbon dioxide levels at the largest volcano on the planet. Do you see any problems with that?

    Yeah, I bet the scientists who spend their whole lives measuring carbon dioxide never thought of that.

    Mauna Loa doesn't really outgas a lot of steady CO2. It comes in bursts, which you can see in the data, and you can independently check whether you may be getting contamination by looking at the wind direction. They have to throw out some data points now and then, but the final record is quite independent of volcanic activity.

    And if you don't believe Mauna Loa, you can look at all the other places where CO2 is also measured, as others have pointed out. Plus direct CO2 flux measurements on land and for the ocean. And the cumulative ocean uptake of carbon. And the decrease in atmospheric oxygen levels as O2 is added to C during combustion to make CO2. And direct economic numbers on how much fossil fuel has been extracted and added to the atmosphere. And you can look at trapped gas in ice cores for CO2 levels earlier than 50 years. And so on and so forth.

    This is an example of someone with such knee-jerk skepticism that they don't do any basic fact checking. CO2 levels are not what the debate is about; nobody seriously argues against those.

    Which you insisted they Google for, or else go and Google the original information in the links themselves, rather than simply telling them where your post was.

    I posted other links to data that point to the fact that the CO2 model is also fatally flawed. It DOES in fact require warming of the upper atmosphere in order to be viable... warming that is simply not happening.

    As I reminded you in my last comment, I pointed you to four published references which contradict your claim that there is a proven inconsistency between the models and the data for tropical tropospheric temperature trends. You ignored them, repeatedly, as you ignore all actual discussion of science. In addition, I pointed you to a data archive which demonstrates that this doesn't even have anything in particular to do with "the CO2 model", since non-CO2 sources of warming make the same predictions as CO2 with regard to tropospheric temperatures. You ignored that too. Hell, even Climate Audit disagrees with you: Steve McIntyre wrote a post admonishing his readers for hanging their conclusions on the radiosonde data.

    I'm afraid that it is not I who is "missing the point". Shannon's entropy relationships CANNOT be divorced from the physical workings of our universe.

    Certainly they can. If you define entropy the way Shannon does, you can derive a bunch of inequalities which are mathematically true no matter what laws our universe follows or whether it follows any at all. It's mathematical deduction.

    If they were, then they would be capable of producing any number you wanted them to.

    No, that's wrong. That's like claiming that in Euclidean geometry, the hypotenuse of a triangle right can have any value independent of the other two sides. The Pythagorean theorem says otherwise, regardless of whether our universe obeys Euclidean geometry or not.

    Now, it happens that Euclidean geometry has something to do with the universe we happen to live in. (It doesn't have to, a priori.) So Euclidean geometry turns out to be a useful mathematical tool when constructing physical theories. That doesn't mean that Euclidean geometry is science.

    However, since Shannon's findings agree with how the universe operates, they are by definition scientific discoveries.

    No: Shannon's theorem's are mathematically true independent of anything in the universe. It happens that the laws of our universe do have something to do with Shannon's theorems, but that isn't any inherent property of the math. It requires actual scientific discoveries to show that, i.e. experimentation and construction of physical theories to describe those experiments.

    If you can find a method by which Shannon's theories may be disproven, then you may have a point.

    No, the fact that they can't be disproven is why I have a point! Mathematical theorems are true or false independent of anything in the universe. If they're proven mathematically true, they're mathematically true. But scientific theories can in principle be supported or disproven by experiment. No physical experiment will or can disprove Shannon's information inequalities, because they are mathematical truths. At best, an experiment can confirm or disprove whether those inequalities have something to do with our universe. But then it's not Shannon's theory that is the scientific endeavor, it's the experiment.

    But as it stands, they are tremendously useful in the proper application of engineering and physics.

    You are still confusing "usefulness in science" with "science". Algebra is useful in science, but that doesn't mean that someone who studies algebra is a scientist.

    Hawking does not refer to "information" because he believes it to be a cool term to use. He refers to it because it is a solid concept rooted in the nature of the universe.

    Arithmetic, differential calculus, and the Pythagorean theorem are all solid concepts which can be used when constructing scientific theories. That still doesn't make mathematicians into scientists.

    Algorithm tuning against empirical data is closer to science, but it's usually more like engineering or statistics than science proper. It becomes something more like science if you're formulating and testing theories about, say, people's phone call behavior or other data-generating processes. But that's not what's usually done: more often, it's just tuning the algorithm parameters to fit different classes of data, rather than investigating the social or physical mechanisms that gave rise to that data.

    No, you're still missing the point. Obviously mathematics is used in science. That doesn't mean mathematics IS science. The practice of science and the scientific method are all oriented toward formulating theories which describe the real world. Mathematics provides tools for formulating theories, but just writing down information-theoretic formulas isn't science. It becomes science when you incorporate them into physical theories, make empirical predictions, test them against observations, and revise your theories. Shannon's entropy relationships are mathematically true independent of how anything in the real world works; that's what makes them not science. Scientific theories are conditional on observed aspects of the world.

Real translation: "I can't defend my claims so I'm going to keep handing out arbitrary `assignments' until you go away and stop embarrassing me."

    Dude, I am not going to look up 600 refutations to every crap argument you linked to off a web site. (And we can be sure that if I don't link to ALL of them, you will continue complain that I haven't "done my homework".)

    But to name just one example, take your wrong claims about tropospheric warming being inconsistent with the models. On that note, see the 2006 CCSP report on temperature trends in the lower atmosphere, Santer et al., Science 309, 1551 (2005), Thorne et al., GRL 34, L16702 (2007), and Allen and Sherwood, Nature Geosci. 1, 399 (2008). Studies you would already be familiar with if you genuinely read the literature instead of quote-mining skeptical web sites. And regarding the further wrong claim that this has anything in particular to do with "the greenhouse gas models", go to the GISS ModelE efficacy of climate forcings data archive and compare the 100-year lat-height profiles for CO2 and solar forcing and see that they both predict the same thing in the tropical troposphere.

    Like I said at the very beginning: pick what you think are the top two or three arguments, link to some scientific studies which support them, and then we can discuss something meaningful. No meaningful discussion goes on when someone posts a hundred random arguments they've quote-mined off of web sites. As I also noted before, that's the creationist "generate wrong arguments faster than they can be refuted" strategy.

    Researchers != scientists. Theoretical computer scientists are usually akin to mathematicians; applied computer scientists are more like engineers. Neither group are scientists. Mathematics doesn't have the real-world connection necessary to be science: if you develop an algorithm, it works or not independent of how the world works. Science is about developing theories describing the world, and testing them using experiments about the world. In computer science you can test an algorithm, but that doesn't say anything about the world. It's not the scientific method as that phrase is used.

And actually, it's looking right now that the amount of warming necessary to significantly slow the thermohaline circulation is large enough that the net effect may still be to end up with a warmer climate than pre-industrial: there is cooling around the North Atlantic, but it's offset by the global warming which caused it (as noted in the THC shutdown Wikipedia article).
