Daisy, I suggest you click the links in the article, which show that these examples are indeed facts/settled science. Your claims to the contrary are simply wrong, and based on a misunderstanding or lack of understanding of the scientific evidence discussed therein. -

15, daisym, The ocean cannot be contributing to the buildup of CO2 in the atmosphere because it is, in fact, itself absorbing a large amount of the anthropogenic emissions (i.e the amount of CO2 in the ocean is measurably increasing, not decreasing). Visit here and here for more information (to start). As far as your claims of assumptions... they are false. You are yourself making a great number of (false) assumptions about the science without understanding it, but I can't direct you to just one or two links to settle that matter, because the gap is too large. You need to study more, and assume less. You will find that the answers to most or all of your own assumptions and misconceptions can be found on this site if you take the time to look, read and understand. The question of who believes that the science is "settled" (itself a strawman argument) not a political question, and is not in doubt. That some would like to make it seem to be a political question is true. That a very, very small but vocal number (like Spencer and Curry) can fool people such as yourself is true. But if you were a skeptical person, you would learn more, understand more, and see through the illusions they present. -
WheelsOC at 08:08 AM on 2 November 2011Fred Singer Denies Global Warming
Singer's comment at Nature includes a lot of content from his letter to the Washington Post dated the previous day (which I can only find as originally posted at WUWT). I instantly recognized the bizarre claims about atmospheric and proxy trends that he seems to have totally invented. Of course none of it is backed by references to the literature, so it's impossible to verify against any particular data. My favorite part is where he cites the BEST line that 70% of US stations are poorly cited, ignoring that in the very same paper they found that these siting issues make no real difference. -

Sorting out Settled Science from Remaining Uncertainties
daisym - "Only one of the three examples for settled science (presented in the first paragraph of the article) is valid fact. The other two examples are conclusions, not facts." Sadly, daisym, all three statements are settled facts. I strongly suggest you follow the links embedded in those three statements in the OP, and look at the copious evidence that supports them. Unless you can point out some references (preferably peer-reviewed) that indicate CO2 rise is not due to our emissions? Or that CO2 does not increase the greenhouse effect, or that the 4% water vapor rise over the last 30-35 years is not acting as a feedback? Otherwise, you are simply making unsupportable denialist claims. -

@ Comment 47 - Kudos on a wonderful graph showing how AGW people see the cooling trends, as compared to the actual warming trend. -
daisym at 07:36 AM on 2 November 2011Sorting out Settled Science from Remaining Uncertainties
Only one of the three examples for settled science (presented in the first paragraph of the article) is valid fact. The other two examples are conclusions, not facts. It IS a fact that the Earth’s surface has warmed. To claim as fact that "...the increase in atmospheric CO2 levels is due to human emissions..." assumes that the 90% (give or take) of Earth's CO2 which resides in the oceans isn't also a significant contributing source of atmospheric CO2. To claim as fact that "...the increase in CO2 is responsible for a substantial fraction of that warming" assumes that the feedback role of water vapor and clouds is factual as well. This isn't the case at all. It’s assumed that water vapor and clouds must amplify the raw CO2 warming to produce the harmful warming attributed to manmade CO2. Without this assumption, there’s no case against manmade CO2. Explaining the slowed surface warming is especially problematic. If natural forces are powerful enough to cool and offset warming attributed to manmade CO2, might they also be powerful enough to cause the warming attributed to man to seem greater than it really is? Who really believes that the science is settled? This is a political question. Too many scientists have yet to embrace AGW to consider the science to be settled.Response:[DB] "Too many scientists have yet to embrace AGW to consider the science to be settled."
As in more than 2-3? You must cite specifics with links to sources to back up your assertions.

Albatross at 07:33 AM on 2 November 2011Fred Singer Denies Global Warming
Thanks Riccardo. Yes, the number of logical fallacies that those who deny the reality of AGW have to make is quite impressive. "Skeptics" and those who deny AGW are really not sure what to do about the BEST results. At the same time they are accusing the BEST team of fraud, they are also claiming that they never doubted it was warming, while also claiming that the BEST data show that "The human component of global warming may be somewhat overestimated", while also bending over backwards cherry picking to try and claim that the BEST data show it is in fact now cooling! They have very vivid imaginations. When the results first came out their immediate reaction was "We never denied that global temperatures are rising!", in about a week that cry has quite miraculously morphed into "The BEST data show that global warming has stopped!". What they are doing beggars belief. Singer's error riddled post was of course given front page status at WUWT, a blog that Dr. Roger Pielke Senior assures is "devoted to the highest level of scientific robustness". Instead of being 'skeptical' about the claims made by Singer (which probably originated from a lobby group which denies AGW and which has a history of playing loose with the truth), Mr. Watts and Dr. Singer were quite happy to propagate the falsehoods and add a few of their own for good measure. In February 2011 Singer said this at WUWT: "I applaud and support what is being done by the Project — a very difficult but important undertaking. I personally have little faith in the quality of the surface data, having been exposed to the revealing work by Anthony Watts and others. However, I have an open mind on the issue and look forward to seeing the results of the Project in their forthcoming publications." Like Watts, he has too reneged on earlier assertions about being open minded about the BEST findings. -

John Russell at 05:49 AM on 2 November 2011Sorting out Settled Science from Remaining Uncertainties
@actually thoughtful writes: "I fear a return of solar activity, as the deniers will then say it is the sun now, it was the sun, and it will always be the sun." Well in many ways they're right -- best first to agree with them that the energy for the warming comes from the sun -- always has, always will -- and therefore the rate of warming will vary according to the sun's output. Then when they're nodding in agreement go on to say that the real issue is that we're increasing the thickness of the duvet on the bed; so as the central heating provided by the sun turns up, under the covers we start to overheat. In other words the concentration of CO2 in the atmosphere is purely passive -- just like a duvet on the bed -- but as it thickens, the heat it traps raises the temperature to uncomfortable levels. This explanation usually works. -

Wonderful, thanks a lot. :) From what I gathered frequentist and bayesian stats give similar results except in corner cases (limited data and very low success/fail rates). I know one of my friends used bayesian stats when he was working at LIGO trying to find those elusive GWs. -
Dikran Marsupial at 05:24 AM on 2 November 2011Baked Curry: The BEST Way to Hide the Incline
Tristan E.T. Jaynes' book is very good, it is hard going, but worth the effort. The real problem with Bayesian methods is that while they are conceptually easier to understand that frequentist methods, and harder to misinterpret, the computation is generally much more difficult, which I suspect is the reason they are not used more widely. I myself am a Bayesian by inclination, but I end up using frequentist methods a lot of the time for that very reason. -

Shocked by Prof. Curry. Until today I had her down as a genuine skeptic, but if so then her Daily Mail interview indicates that she is hideously naive with regard to the press. If she's a genuine skeptic, how can she be so daft as to give ammunition to a newspaper that will turn her into a mouthpiece for the denial industry, whether she likes it or not? Can she not understand that the damage she's done by talking to the Mail far outstrips any flaws in the BEST analysis, even if she's completely right about all of her gripes? Or maybe she's been seduced by the dark side. Wonder if David Bellamy has a spare Darth Vader helmet he can lend her? Or perhaps she feels insulted by something Muller has done, and is getting her own back, not caring about the effects on public opinion (except against him). There is no way of looking at this that casts her in anything other than a very poor light. -
Dikran Marsupial at 05:18 AM on 2 November 2011Baked Curry: The BEST Way to Hide the Incline
les thanks for the links. The best summary of the key problem I have seen is that "we want evidence of a significant difference, not significant evidence that a difference exists". It is very rare for two samples to actually have the same population parameters (e.g. for a drug to have precisely no effect - if that were true it wouldn't have gone as far as a clinical trial in the first place), so if you have a large enough population, you can always reject the null hypothesis even if the actual difference is way too small to have any real meaining. Testing for normality is the classic example of this. Random variables are only truly normally distributed in some assympotitic limit, which never actually applies in the real world. So when you are testing for normality you usually know that the null hypothesis is false from the outset, you are just checking to see that your sample is small enough that it could be confused for a normally distributed sample, and hence assuming it is normal to make the maths easier probably won't cause a problem! -

Thanks for the link DM. [OT]You have no idea how frustrating it was to go through a stats major (The MA was no different either) at university learning nothing but frequentist stats even though my lecturers acknowledged that significance testing was outdated and that bayesian analysis was a better approach. There was nothing in our textbooks (~2005) more recent than procedures from the 1950s. I've been meaning to teach myself bayesian stats for a while now. Is there a text you'd recommend?[/OT] -

65 - Dikran Yes, thanks. I think it helps to emphasis that she is not testing for a change of rate / rate staying the same (null hypothesis). But that the specific time period shows no warming... then here statement from Tamino post "“There is no scientific basis for saying that warming hasn’t stopped” is talking about whether things changed .... so she has clearly applied the wrong test for the statement. as an aside... talking about the strangeness of hypothesis testing... this The Cult of Statistical Significance and thisare quite fun. -
Dikran Marsupial at 04:50 AM on 2 November 2011Baked Curry: The BEST Way to Hide the Incline
Tristan Have you read E.T. Jayne's paper on confidence intervals. It is well worth a read, I especially liked the example of a correctly constructed confidence interval where you caoul be 100% certain from the sample of data that the true value of the statistic could not possibly lie within the confidence interval. While it is a bit polemic in style I found it very helpful in understanding what confidence intervals tell you and what they don't. -
Dikran Marsupial at 04:46 AM on 2 November 2011Baked Curry: The BEST Way to Hide the Incline
les Essentially the important issue is that frequentists hypothesis tests are not symmetrical; if we exchange the null hypothesis with the alternative hyopthesis, we do not necessarily get the opposite answer. Essentially the test assumes that the null hypothesis is true and it is up to you to prove that it isn't. This gives a correctly cautious approach to assessing the evidence for our hypothesis. Prof. curry though is arguing FOR the null hypothesis used in the test for the presence of a warming trend. So she is assuming that she is right and it is up to the data to prove he wrong, which is very different and frankly dangerous approach to statistical analysis. The correct thing to do would be for Prof. Curry to re-frame the argument, so that warming at the long term rate were the null hypothesis and that the alternate hypotheisi were that there had been a change in the trend. She would then have to demonstrate that the null hypothesis (no change in the warming rate) were unlikely to be true. In this case, the time period is so short that the null hypothesis is unlikely to be rejected in either test, which is because there is too little data to be sure either way. However, Prof. Curry is the one arguing that there has been a change in something, so Occam's razor (the simplest explanation is probably correct) suggests that we should have a preference for "no change" over "change" to some degree. If this sounds confusing, don't be worried by that, the more I look into frequentist hypothesis testing, the more I wonder how we arrived at the recipe we currently use in science! -
Steve Bloom at 04:45 AM on 2 November 2011Not so Permanent Permafrost
Re #s 7/11: AIUI, high northern latitude Eemian warming resulted fairly directly from Milankovitch forcing. That's not the case now, and in particular warmth carried to the Arctic by warming currents (originating in e.g. the Agulhas) is a big factor. Also, the current temperature rise is much faster than during the Eemian, which seems likely to result in somewhat different melting effects (and much greater forcing per unit time). But the main lesson from the Eemian seems to be that a relatively mild push (compared to what we're doing) resulted in a lot of melt, although mostly of land-based permafrost rather than the much nastier stuff that lurks off the coast. A point I wanted to add that may have been mentioned in one of the prior related articles here but IMO doesn't get mentioned enough, is the geologic uniqueness of the yedoma and the shallow ESS permafrost/clathrate deposits. Their presence requires, variously, a shallow Arctic Ocean, a deep freeze (noting that this is only the third such of the Phanerozoic), an extensive Arctic coastal area that doesn't glaciate, and finally major rivers that dump large amounts of carbon-rich sediment into the shallow coastal zone. I haven't seen a scientist address this exact point, but the uniqueness of this combination of factors (leading to immense amounts of CO2 and methane mobilizable by us) seems clear enough. It's a whole nest o' Krakens, and we're stepping in it. -

"There is no scientific basis for saying that warming hasn’t stopped [since 1998]" Which is wrong, but what she meant to say was: "One cannot reject the null hypothesis of 'the warming has stopped since 1998' using the BEST data" She's right but it's pretty meaningless. -

les at 04:17 AM on 2 November 2011Baked Curry: The BEST Way to Hide the Incline
61 - Dikran Marsupial Just for clarification... I'm a bit confused about what her (or the) Null hypothesis actually is. Surely it's not "no warming". That statement is just "the slope of the line is zero" and 'zero' there is just an arbitrary number, could be any other number. (the zero in no warming is not the same as Null!) I'd have though the null hypothesis should be "the trend in period X is no different to the trend leading up to period X" for some reliable measure of preceding trend. Surely? No? As an analogy. If I wanted to test the breaks on my pushbike, either I could stand next to the thing (bike not moving... [zero] null hypothesis applying the breaks makes no difference to the speed) and squeeze them a 10,000 times (nice low p-value) and go, well the bike isn't moving so they must work. Or I could roll the bike at some speed (null hypothesis; applying the breaks makes no difference to the speed) and squeeze the breaks once (horrid low p-value, illustrating the p-value fallacy while we're at it) and see if the bike stops. -

Dikran Marsupial at 02:53 AM on 2 November 2011Baked Curry: The BEST Way to Hide the Incline
Tristan, reporting the outcome of a frequentist hypothesis test is a rather subtle issue, the problem with reporting the p-value is that it is only half the story. It is the probability of observing a statistic at least extreme assuming that the null hypothesis is true. The key point is that the alternative hypothesis doesn't enter into the calculation anywhere, and the probability of observing a statistic at least as extreme under the alternative hypothesis might not be greatly different. The danger if presenting the p-value is that it will be interpreted as the probability that the null hypothesis is true (the "p-value fallacy"). The thing to do is to always interpret the result of the test in the way that provides the least support for the argument you wish to make, and Prof. Curry is doing the exact opposite of that in suggesting that the non-significance of the warming trend is evidence that there is no warming. Like Prof. Pielke she is arguing for the null hypothesis, rather than against it, so she needs to talk about the statistical power of the test to make her case (or to re-frame the test so that warming at the long-term rate is the null hypothesis). -

Tamino has a new post up challenging Dr. Curry: "You stated explicity that warming has stopped, your latest is vague enough to be satisfied by “slowdown” but the first two say “pause” and “stopped.” Either way — slowdown or stop — you need to provide some actual evidence that the trend has changed. The one thing that nobody has yet seen, is your scientific basis for any of these claims. Question #1: Do you still maintain the above statements? No ambiguous answers, please, it’s yes-or-no for each statement. Question #2: If any answer to #1 is “yes,” then what’s your scientific basis for claiming that the trend post-1998 (or post-2001 or whatever) has changed?" I will be surprised is she provided forthright answers. More likely she will engage in more hand waiving and some other carefully constructed narrative to try and caste doubt or suggest incompetence by someone other than herself. Or she will claim not to understand what the fuss is about, or the meaning of Tamino's post. She tends to do that when confronted with inconvenient facts. -
Dikran Marsupial at 01:46 AM on 2 November 2011Baked Curry: The BEST Way to Hide the Incline
Tom Curtis Yes, the Bayes factor does ignore the prior probabilities, however you can put them back in by multiplying the Bayes factor by the ratio of prior probabilities to give you the ratio of posterior probabilities. However the problem with priors is that a "skeptic" can dismiss the argument by saying that your priors are unreasonable. Equally they could say that solar-tidal forces means that the PDO oscillation ... blah blah blah ... natural cycles mean that the prior ratio for cooling to continued warming is 100. The Bayes factor has the advantage of telling you by how much your prior belief should be altered by the evidence provided by the data. The advantage of the Bayes factor is that it is a continuous measure of the relative support from the data for one hypothesis over another, rather than a binary decision of "satistically significant" or "statistically insigniicant". This means the key problem here, that a non-significant trend not necessarily meaning the null hypothesis being true, doesn't arise as it is clear from a Bayes factor below three. -

Dikran Marsupial @50, I dislike likelihood measures because, by ignoring the relative a priori probabilities of two hypotheses, they will often favour the hypothesis with the least a priori probability, while Bayes theorem would favour the other. So, while useful in some applications, likelihood measures are not universally applicable, and I am far from certain that Bayes factor would be applicable in this situation. -
Tom Curtis at 01:25 AM on 2 November 2011Baked Curry: The BEST Way to Hide the Incline
CBDunkerson @49, you are correct that I presupposed the period of the BEST record. Without the caviate, I think the conditions would need to be stated: There exists at least one interval with a statistically significant positive trend such that: a) The period 2001-2011 is a sub-period of that interval, and b) The interval contains no sub-periods with a statistically significant zero or negative trend. Given that these conditions are satisfied, the statistically significant positive trend is a sound scientific reason to accept an underlying positive trend in the interval 2001-2011, and the lack of any sub-periods within that interval (including 2001-2011) with statistically significant zero or negative trends means there are no defeaters for those sound scientific reasons. -

muoncounter it may not be a trend, but it is significant! ;o) dana1981 I am in complete agreement. Even giving Prof. Curry the benefit of the doubt, her comments do her little credit. It doesn't overly surprise me that scientists don't do a good job of communicating the science, the really susprising thing is that they have not actually performed the required statistical test of their hypothesis. Bob Loblaw ;o) I once read a microbiology paper where a "quadratic response surface" was fit to two points with one independent variable! Fortunatly the software wisely decided that the coefficient of the squared term was zero (which was faithfully written down in the equation for the model). Tom Curtis Nice comment. Perhaps the Bayes factor, which gives the ratio of the support from the data for two hypothesis (taking the uncertainties into account), would be a better approach. If the Bayes factor is less than three the evidence is generally considered "barely worth mentioning", which I suspect would sum up the 2001-present trend.

Presumably you intended this to refer just to the duration of the BEST record, but without that caveat being explicitly stated there are technically very large intervals (e.g. the past 50 million years) for which it would not be true. Here's a thought... when was the last statistically significant zero or negative trend within the confines of the BEST record? I'm guessing that it was decades ago. -

Tom C #35: If I may repeat your points with a minor correction, "1) We have strong evidence from medium term trends (greater than 17 years) that the temperature trend is close to 0.27 degrees C; 2) No short term trends provide evidence significant enough tobringsuggest the evidence in (1) is misleading about the future temperature trend." I agree with your statements 1 (where the stated trend is in deg C per decade) and 2; a most cogent and compelling summary. The implication of (2) is clear: it is nonsensical to go on about 'there is evidence for a change in trend' or 'there is no evidence that the trend hasn't changed.' In the first case, because it is incorrect; in the latter case, there is no evidence that a lot of things have not happened; what kind of science deals with that? Unfortunately, those who are in denial must find something to deny, so they will go on with this nonsense. That leaves them to practice their chosen field: pseudo-skeptic climastrology, which now includes the study of the lack of evidence of that which hasn't happened. -

38, garythompson,...how can you look at this graph and say that warming has not stopped.
You are so right! Take a look at this graph. Warming hasn't merely stopped, but cooling has started. In fact, cooling started back in 1973 and the globe has cooled since. The fact is that all trends are negative since 1973, without pause, and therefore the inescapable conclusion is that there has never been any warming. [Hint: A "skeptic" can pick any point in time in the past 30 years and prove that the globe is cooling. What does that tell you?]

You know, I read Curry's statement, "This is 'hide the decline' stuff", and immediately thought; 'what, you mean people grossly misrepresenting the data?' She then proceeded to grossly misrepresent the data. So... I agree with Judith Curry. This is 'hide the decline stuff'. The same sort of nonsense as the claims that 'hide the decline' referred to a decrease in global temperatures, rather than the divergence problem in recent tree ring proxies. That Curry is still promoting that old falsehood, and now 'shoring it up' with new misrepresentations places her towards the bottom of the 'Scientific' Denier Credibility Scale. Somewhere around Spencer's level I'd say (i.e. higher than Singer / lower than Pielke). -

Logicman's upcoming piece should be interesting, although with the current (and growing) furore over at WUWT, he might be forced into a few quick re-writings in order to keep up with the gathering pace of the spittle flying over there. And Watts might want to keep an eye on some of his sycophants. Some of their guff is skirting toward libel. -

An excellent and timely piece. I think it's a good thing that Curry et al are nailing their tattered colours so firmly to the mast of warming having stopped. It's become increasingly obvious to everyone that it hasn't; and this conviction is likely to deepen with time. Curry and her ilk can only cherry pick these figures for so long before there are no cherries left on the tree - and no fig leaves either...
