  1. The paper that started modern climate modelling on How Two Scientists Accurately Predicted Global Warming in 1967 (medium.com) · · Score: 1

    If you read any of the literature, you'd know that this is the reference-- the Manabe and Wetherald paper was the first to fully model the co-effect of carbon dioxide and humidity in a convective atmosphere, and is the one pretty much everybody references.

    Here https://www.carbonbrief.org/pr... for example, or here https://www.skepticalscience.c...

    Manabe was the grandfather of global circulation models-- pretty much all the models that exist today can be traced back to his work. This wasn't a "random" paper-- this was the paper.

  2. Wow, in 1967 scientists predicted global warming, with a study that half a century later has proven to be largely accurate...

    BUT, did that 1967 take into account all the dramatic changes that have been under-taken since 1967 to shrink the world's carbon footprint?

    No. If you'd read the article, not just the summary, you'd see that the paper did not try to predict how much carbon dioxide would be produced. It predicted if this much carbon dioxide is produced, then this much warming would occur.

    The comparison of prediction to experiment-- if you'd read the article you'd know this-- was to look at how much carbon dioxide actually was put in the atmosphere, and compare the warming to the amount predicted for that amount of carbon dioxide.

    The theory turns out to be a remarkably good match to the data. Good work, Manabe and Wetherald.

And, since they do this deletion a lot, they are very good with the Wikipedia bureaucracy and know exactly how far they can go without getting counted as "edit warring"-- and how to entice novice editors into breaking one of Wikipedia's invisible rules and getting banned.

    The article says : "As detailed in a 2013 feature in the MIT Technology Review, the decline of active editors with more than 10 edits under their belt has been attributed to the increasingly bureaucratic nature of the editing process. The semi-automation and stricter editing process was initially launched as a way to combat vandalism on Wikipedia pages. Although the new protocols did result in a decrease in vandalism, it also resulted in a steep drop off of new editors that stayed 2 months after their first edit."

    Your graph cuts off in 2010.

    I notice you don't bother to cite any data supporting your claim of a trend of "constant or declining carbon emissions". Unless you have some data showing such a trend-- and a trend long enough to be meaningful-- I stand by my statement.

    If you're quibbiling, Manabe and Wetherald's calculated climate sensitivity was 2.4, not 2.0. [...] (with your rounding of "2.4" down to "2" corrected)

    I didn't round, that's what the paper says: "According to our estimate, a doubling of the CO2 content in the atmosphere has the effect of raising the temperature of the atmosphere (whose relative humidity is fixed) by about 2C". You really need to read the paper, instead of random blog posts.

    I'd actually checked the number out of a textbook that I happen to have near my desk (Liou, An Introduction to Atmospheric Radiation, 1980, if it matters-- my usual go-to book on atmospheric light scattering) instead of digging up the original paper. But turns out it's not hard to dig up the paper, it is on the web several places, so it's easy enough to check: http://ruby.fgcu.edu/courses/twimberley/EnviroPhilo/ThermalEqu.pdf

    And, how about that?-- you're almost right. "About 2C" is indeed what is says... in the abstract.

    In the body of the paper, though, they give the calculated result to more than one figure. Table 4 and table 5 shows their calculated results. The increase from 300 to 600 gives an effect of 2.36C (for fixed relative humidity and "average cloudiness;" slightly higher for clear skies).

    So, I withdraw my statement that you rounded their result down. In fact, it wasn't you: they did the rounding. Nevertheless: the number was 2.36 (but the parts after the decimal point are probably not significant.)

    For what it's worth, their 1975 paper, calculating with a three-dimensional model instead of the 1967 2D model (which means that they have both oceans and continents, instead of an average of ocean and continent), came up with 2.39 degrees per doubling-- nearly the same.

    I don't see much real information in the rest of your post, you're arguing your opinion and policy, and not significantly disputing facts. You're saying you don't like the models because you don't understand the feedbacks, but you're more or less ok with the results to the first significant figure, although to a second significant figure you prefer a number slightly on the lower side but still within the error bars, but you think that existing societal trends will reduce CO2 emissions anyway so the predicted warming will be lower than the highest value of the IPCC scenarios (which is what the IPCC also seems to thing: that is the high case.)

    OK. I'm not sure that there's enough in that to bother arguing with.

    I will, however, quibble with two points:

    There is nothing "paradoxical" about it; irrational climate change deniers are largely a figment of your imagination.

    No, irrational climate change deniers are certainly out there, and say all sorts of bizarre things. However, you have clearly shown that you are not an "irrational climate change denier," since you're arguing with numbers based on the real science.

    The files where copied locally using cp -R based on the time and date stamps. It was a 25MB per second copy(i.e. USB2.0).

    So, what the metadata showed was that at some point the data was copied at 25MBits/second. What wasn't shown, however, was at what stage in the hack this transfer speed happened. The files could have been stolen off a server at one speed, but then copied to another file at a higher speed sometime before being released. 25 MBits/second isn't necessarily the speed at which they were initially copied.

    also, note that this is MegaBITS per second, not bytes. In fact, high speed internet connections do reach and exceed this speed, so the analysis doesn't even particularly show that the files weren't stolen across an internet connection.

    20th century patterns aren't "current trends". Current trends suggest constant or declining carbon emissions.

    The data shows otherwise: http://www.energytrendsinsider...

    But that's irrelevant: the question what if current trends continue is still an interesting one to ask, even if the answer is "current trends won't continue."

    But, by the way, why should "current trends continue" be "economically utterly implausible"? It's not economically implausible now, why does it suddenly switch to being implausible?

    Because the price of fossil fuels goes up as they are exhausted

    Historical data shows that fossil fuels don't get exhausted, because new supplies are found.

    and the price of carbon neutral sources are steadily falling. Not taking that into account is absurd.

    And that's why they also looked at the effect of substitution of other sources.

    Basically, you took a whole array of different scenarios put forth by IPCC to look at the effect of all sorts of different possible things that could happen, you took the most extreme one, and you say "look at their prediction! It is absurd!". That wasn't their "prediction". That was their analysis "here is the result if this one particular scenario takes place."

    I gave this as an example of their use of economic predictions; they use economic predictions in all their analyses, as well as predictions about the effects of government policies. Their other scenarios suffer from analogous problems, it's just not worth going through every one of them to get my main point across, namely that their conclusions are not just rooted in "basic physics" but require lots of other assumptions that are far more speculative and not rooted in any science.

    My objection stands. They gave a wide variety of different possible scenarios but you chose to point out only the most extreme what-if scenario and ignore the fact that this was only one of many different scenarios. If they hadn't looked at a "what if current trends continue" scenario, then that would have been dishonest.

    As you pointed out very clearly in your previous post, the current IPCC best estimate of climate sensitivity, 3 plus or minus 1.5 degrees per doubling, is pretty much identical to the one-dimensional constant-humidity model of Manabe and Wetherald.

    No, their most likely prediction of 3C is not the same as 2C, it's 50% larger.

    If you're quibbiling, Manabe and Wetherald's calculated climate sensitivity was 2.4, not 2.0. That is 25%, not 50%. And within error bounds of the current best estimate. You do know about error bounds? This is how science works.

    I'm annoyed at people attacking the science because they don't like proposed policies

    Stop pretending that there is something like "the science". People attack some of the science in the report because some of the science is in fact weak. Scientific conclusions and arguments are only as strong as the weakest link, that's why many people consider the overall conclusion of the report to be weak even if they (like me) agree that parts of it are strong.

    You've been asserting that some of the science is weak, but you haven't shown that-- you've just said it over and over again, on the assumption that repeating something enough times is as good as actual evidence.

    Nevertheless, paradoxically, you seem to actually agree with the conclusions of the report, since (with your rounding of "2.4" down to "2" corrected), you quote a climate sensitivity within the error bars of the current best estimate.
