    Well, it's less silly than arbitrarily declaring what someone else's margin of error is. Especially if you have no idea what "80%" refers to. Relative temperature? Absolute temperature? Heat content in megajoules? Watts per square meter of forcing?

    I'm not really terribly concerned with your "format requirements". The data is presented above, and your ignoring it only harms your own position. But let's have you quit dodging around for a minute. What part of the theory of AGW do you think is inaccurate? "The whole thing" would imply, e.g. that CO2 does not absorb IR, that it does not build up in the atmosphere, that the Earth is not warming, and many other things. Given how easy some of these things are to measure, I don't think you're making that argument. If, as I said a minute ago, you can't identify any part of the theory you think is unsound, we are forced to conclude that you think the theory is sound. So what exactly is your disagreement?

    Successful predictions include surface warming and stratospheric cooling coincident with a rise in CO2 levels, and stronger warming effects at the poles. Are you under the misapprehension that producing fine-grained projections of global temperature is the only thing that climate scientists do?

    The challenge I put forth asked for correctness of just 80% for any cited prediction

    Studies usually already include their error margins. If a prediction comes in within its own error margin, that is a successful test. Surely you don't apply your own arbitrary standards to other physical sciences? As it happens, results within the error margins of prediction are true for Hansen et all (1988), linked previously, for Plass (1956), Arrhenius (linked previously), and most accurately by Sawyer (1972), who managed to get both the magnitude of increased emissions and the resulting temperature increase exactly correct. I apparently wasn't clear when I gave you the temperature predictions earlier for Sawyer, Plass, and Hansen. I assumed that you would be able to find a graph of global temperatures for the 20th Century. Here's a graph for you, which corroborates their findings. I hope it's not too much trouble to be able to look at my previous posts for the numbers.

    Also, Arrhenius (1896) and Callendar (30s-40s) were confirmed in the mid-50s with CO2 and temperature measurements. You could also consider Plass and Kaplan (1952) to be confirmation of the previous work on the matter. Also, you will note that Hansen's spacial distribution of the temperature anomaly was very accurate. Looking at graphs in the 1995 IPCC report their prediction (p40) of the warming trend matches the observed warming through to the present quite well.

    We see scary predictions published — even on Slashdot — about once a week.

    If you're getting your scientific information from the popular press, you're probably being misinformed in some manner. In my experience newspaper articles are rarely peer reviewed, and I don't think I've seen very many cited, or that have citations. As it happens, I believe most of the articles on Slashdot are concerned with weather events and annual records.

    does this mean, you admit, no predictions I seek have been made until "just recently"?

    What you want isn't actually a test of the science in the way you think it is. Global climate models cannot be used to disprove AGW any more than epidemiological models can be used to disprove the germ theory of disease, and Kerbal Space Program is similarly not a test of relativity. Economists can construct models to show that rapid expansions of the monetary supply cause harmful inflation, and there is empirical evidence to support this idea. Constructing a model to predict the exact effects of the Fed's Quantitative Easing program would be something of a challenge. Failure to model something accurately means that your model is inaccurate, not that the theory is wrong. Are climate models inaccurate? Of course they are! Every model is inaccurate. All of science is inaccurate, it's inherent to empirical observation. The question is to what degree they are useful, and to begin to be able to answer that, I would suggest you start here or

    The format is perfectly reasonable — you do not disagree. And yet, despite replying here yet again — and putting a considerable amount of effort in crafting the reply too — you are unable to complete the challenge.

    If you are more concerned with formatting than content, that's your own issue. Various studies have predicted warming which has occurred, to the detail specified in their error bounds. Namely, Hansen, Plass, and Sawyer. They published in different years, and the period their predictions covered were generally through to the year 2000. It would be harder to find a model that did not show warming, in point of fact.

    Mostly though we're just recently getting to the point of being able to make specific temperature forecasts; it's been an intensive task trying to replicate the historical data. And even today, we can only guess at what emissions levels are going to be -- those don't follow physical laws. If you're only going to be satisfied with exact answers, you're going to have to look somewhere other than science -- error is inherent to empiricism. Demanding an arbitrary level of precision allows you to disregard any theory you like, from gravity to evolution.

    Begging the question — are these facts really accepted? By who? By scientists? Who are they and what successful predictions have they made? Go back to square one...

    Tyndall, Boltzmann, Arrhenius, and various other scientists since then. Many people predicted warming, which has since then occurred. If you'd care to specify what part of the theory you find insufficiently well supported, I can try to find you a citation.

    Your demands for citations are cute. If they're not in the right format, you won't read them. I'm sure that will make them go away.

    To illustrate, that we've seen both kinds of predictions, and that the climate science has a long way to go to establish its credibility. These cooling papers came after Arrhenius, did not they?

    Again, we can find contrarian research published about plate tectonics decades after it was accepted science. The existence of papers is not an argument for their credibility.

    Arrhenius' first paper on the subject of warming is here. His prediction was about 4-6 degrees per doubling of CO2, with greater effects at the poles. That's on the high end of current estimates, but given the amount of hand-calculation he had to do, it's still a pretty impressive result.

    Most of the early work on climate change was proving that it was possible for the climate to change at all, and as you can see in Arrhenius' paper, they mostly deal with the planet in an equilibrium state, and don't account for ever-increasing levels of CO2. One early attempt at modeling the globe in order to make these sorts of predictions was Hansen et al, 1988. He overestimated warming by about 15-25%; this article gives a post-mortem on his predictions. Essentially, using the same model with one slightly different physical constant reproduces the temperature trend far more precisely. An earlier study (Plass 1956) predicted a rise of 1.1 degrees C per century, assuming 1950s emissions levels. Warming since the 1950s has been on the order of .8C, so his prediction was something of an underestimate. Sawyer's prediction in 1972 was .6C by the year 2000, which was much nearer the mark.

    However, you're also reversing the burden of proof. Basic physical laws suggest that a higher partial pressure of CO2 will warm the Earth, and simple laboratory experiments show a strong positive feedback from H2O.

    Great! And this was all known this for decades (if not centuries), right?

    The laboratory experiments on the infrared absorption of various gases date back to Tyndall (1859), and general radiative laws derived by Boltzmann (1884). A more specific overview of radiative forcing effects can be found in Myhre et al, 1998, if you're interested. So for the general idea that CO2 affects the temperature on Earth, you can look to any of the above for confirmation, or grab an IR camera and take a photograph.

    So if CO2 affects the global temperature, and CO2 is measured to be increasing (which presumably you do not dispute), then wouldn't it be obvious that temperature must also increase? Not so fast! The absorption bands of CO2 and H2O overlap, and the atmosphere is so full of water vapor that it periodically precipitates. Clearly anything CO2 could do, H2O must already be doing, right? Bzzt. The flaw in this thinking is that because H2O precipitates out before it reaches the upper atmosphere and CO2 does not, allowing the latter to build up in the upper atmosphere (Kaplan 1952). Specifically, it extends the CO2-rich layer further out into space. There are a couple more details about where emission happens at what probability for a given photon of a given energy, and how many times it can expect to hit something on its way up, but again, your IR photograph should tell you that the mean free path is pretty short. This paper gives an overview of Earth's radiative balance.

    All governments are monopolies -- on violence, if nothing else. The proper function of government is to address market failures. In some cases, this involves providing consumer information. In others, it means breaking up collusion. However, markets are not appropriate to solve all problems: there is such thing as a "natural monopoly". When competition is not desirable or possible, or when services are required to be universal, private ownership is equivalent to a private tax. Governments could be said to be the natural monopoly of natural monopolies, but that's getting a bit clever.

    No, Arrhenius was pretty clear about the warming effects. Frankly I don't know why you would mention these cooling papers, they were a minority view at the time they were published, and have been refuted since then. We can find relatively recent papers denying plate tectonics as well.

Also, your statement that clouds cause cooling is not quite correct: clouds contribute to both warming and cooling.

    However, observations using the INTEGRAL telescope, through the all-sky SPI-ACS instrument, indicate that the amount of energy in gamma-ray and hard X-ray emission from the event was less than one part in a million of the energy emitted in the form of gravitational waves, concluding that "this limit excludes the possibility that the event is associated with substantial gamma-ray radiation, directed towards the observer." If the signal observed by the Fermi GBM was genuinely astrophysical, SPI-ACS would have detected it with a significance of 15 sigma above the background.[50] The AGILE space telescope also did not detect a gamma-ray counterpart of the event.[51]

    It's also worth noting that while Fermi can tell the origin of a signal to some degree, it's not what you would call pinpoint accurate. "The region not occulted by the Earth contains 75% of the probability of the localization map," which means that the other 25% was pointing towards a terrestrial gamma ray burst but that's not what we're here to science, darn it!
