       Bad news for climate contrarians – 'the best data we have' just got hotter
       

       @  17  Yes I did look at the web site and although I read "The large volume of data associated with the more frequent observations (such as one minute data) limits the quality control of these observations to automatic processes, whereas some human interaction is involved in quality controlling maximum and minimum temperature data"  I didn't see any reference to what the human interaction was nor were minimum and maximum cut off points and their range for automatic temperature quality control mentioned.  It is these to which I was referring.  As I noted, BoM did change the temperature from  the -10.0C cut off that had previously been used to -10.4C.   The inference that could be drawn, particularly  by those receptive to such inferences, is that the BoM would not have reversed the initial change had it not been noted by others

       Why the Republican Party's climate policy obstruction is indefensible
       

       nigelj@27,

       My concern is deeper than critical thinking. Why don't the supposedly advanced societies raise the vast majority of their members to be 'moved by rational consideration of distant motives'? Why do they fail to raise responsible considerate adults?

       The best explanation I have is that those who want to get away with the easier/lazier, less responsible, less considerate behaviour would struggle to be winners in such a society.

       And once a few of those types get away with their undeserved competitive advantage others are eager to follow the unacceptable examples.

       As more people focus on believing whatever they want to excuse what they want to get away with the society devolves to the point where the callous greedy and the intolerant can actually win popularity contests by the easy appeals to tempt people to try to benefit form being greedier and less tolerant (far easier than getting people to be moved by the rational consideration of distant motives). And if things are allowed to degenerate far enough the most abusive and aggressive among them can win the Presidency and the unfit for Leadership likes of that 'Winner' can be appointed to leadership roles by that undeniably undeserving President.

       And the fuel for all of this is the creation of unsustainable and undeserved perceptions of prosperity and opportunity by over-development of the economy in the wrong direction (unsustainable and damaging development).

       A main demand seems to be that people will change as long as the change is an improvement on their current developed perception of prosperity and opportunity (or fond regional memories of the prosperity of past-times before an unsustainable way of living came to its inevitable and deserved end).

       Trying to get people to understand climate science also requires many of them to understand the unacceptability and unsustainability of their perceptions of personal prosperity and opportunity. And it requires many wealthy powerful people to accept that they deserve to lose the economic gambles they made.

       A critical thinker is not immune to the powerful temptation of personal Winning. In fact, a critical thinker can choose to behave less acceptably and be 'very smart' about how they behave unacceptably.

       ubrew - models dont put ENSO/PDO etc into model at all.  These are emergent features from running the physics. Its just that because they are essentially chaotic, each different model run produces a completely different wiggle.

       I not sure about the subtely lost - the deniers writing up about perceived model/obs mismatches have to get the data in first place and publications very much emphasize what models predict and dont. If someone wont read your text, how are you supposed to communicate?

       "What is the point is that the use of these filters and their set points have not been generally disclosed."

       Hmm, so on the BOM page for Observation of Temperature we find under quality control:

       "Once the data arrive at the Bureau they proceed through a number of quality control processes to detect errors, which includes checking for:

       • Consistency in the observations (e.g. checking that the maximum is not less than the minimum);
       • "Flat-lining", where values do not change for several days;
       • Values close to or outside the normal climatological range of values for the time of year (which may be real or incorrect).

       (Emphasis mine). If putting this on their web page isn't "general disclosed", what more do you expect? Took me seconds to find, did you bother to look? This is more faux outrage from Nova/Marohasy/deniers because they dont know what they are talking about.

       Scaddnp @17, one of my obsessions is why people dont teach critical thinking better in schools. It's crazy that they don't. I agree maybe it's so people dont question religion too much.

       Another additional reason might be so people dont question and analyse politicians or lawyers too cleverly, or authority in general. Never underestimate the power of lobby groups behind the scences influencing how schools do things. I suppose teachers might not like it either, but they have a duty to teach these skills in my view.

       Tom Curtis @23, yes we have so many lies by omission in sceptical climate articles it's frustrating. Thank's for the link to the NASA explanation for adjustments.

       Regarding these temperature adjustments. The  graph on page 11 in the Wallace research study appears to be land temperatures, im not sure it doesn't say.The adjustments adjust temperatures upwards anyway. The research is critical of this, but doesnt really say why in any detail, just vague accusations.

       This link  below shows a broader picture, with graphs showing adjustments for all three: land, ocean and combined. It also gives explanations on why they are made.

       variable-variability.blogspot.co.nz/2015/02/homogenization-adjustments-reduce-global-warming.html

       It shows land adjusted upwards, oceans steeply downwards and the net result is land and ocean combined actually adjusted downwards slightly. Interesting that the Wallace study didn't bother to mention all that. You are obviously aware of all this, but its a great article with clear visuals, and may be of interest to us non experts.

       This article is also interesting, and gives more detail on why adjustments are made

       theconversation.com/why-scientists-adjust-temperature-records-and-how-you-can-too-36825

       I cant see a problem. The links all provide good reasons for adjustments to compensate for various biases, and urban heat island effects, etc,etc. The fact that the land / ocean combined is actually downwards seems lost on the sceptics. 

       I hope Im interpreting it all right. But the graphs in my link are pretty clear and the sources legitimate.

       Maybe mistakes are made in adjustments, but I would like to see proof and none is on offering. It seems unlikely that every adjustment would be an error, especially when you look at the checking process and how good it is. It seems unlikely there is a global conspiracy across countries to adjust things one way on land. This is in the region of nasa moon landings conspiracy nonsense. And if so why would they do the opposite for the oceans? 

       Like you say it doesn't remove the alleged "cycles" anyway.

       Bad news for climate contrarians – 'the best data we have' just got hotter
       

       Interesting that Jo Nova should be mentioned in posts 13 and 14.  In actuality the original  report came from Jennifer Marohasy and was picked up and put on line by Jo Nova.  Personally, I prefer, whenever possible, to go to the original source rather than subsequent re-iterations as this approach removes the possibility of distortion on retelling.  And @13 as for the "automatic recording of any value regardless of how nonsensical it is"  it is obvious that, after challenge,  the -10.4C  was recorded  and eventually pubished as such.  This rather negates your point but raises the interesting questions as to why the filtering was reversed and why the -10.4C value was not entered in the CDO database.  

       And @14 your guess about filters on upper temperatures might well be right and my guess is Jo Nova has no problem with filters on low temperatures either.  That really isn't the point. What is the point is that the use of these filters and their set points have not been generally disclosed.  That they have not may introduce another  element of distrust as to the veracity of the readings to those who are already distrustful of what they regard as manipulation of temperature data

       Curiously the very low temperature on July 2 at Goulbourn Airport was not reflected by similarly low temperature at the nearby stations of Goulbourn TAFE College, Taralga Post Office, or Nerriga (the later two being very distinctly rural stations).  Please note also that BOM preliminary (ie, non-audited) data for Goulbourn Airport show the -10.4 value, contrary to rocketeers claim.  The curiously low values at the airport relative to nearby stations, however, suggest there may have been some factor causing spurious readings.

       Why the Republican Party's climate policy obstruction is indefensible
       

       scaddenp@24: none of that is a subtlety the deniers claim to understand.  'In the Eyes of the Law' (which are the same 'eyes' that would today be calling for a 'honest-broker' red team/blue team debate on climate change), the models didn't match reality, and therefore are wrong.  You know, and I know (well, maybe I don't know, exactly), that a random-number-generator is probably used to determine if 'this year' is a La Nina/ a neutral/ or an El Nino.  I presume that most models don't even include the PDO cycle, or knew that the ramp-up in Chinese and Indian coal usage, with associated aerosols covering the N Pacific and Indian Oceans, was imminent.  But what is that saying, other than that they are friggin' models?  Only a Lawyer is going to 'prosecute' a model for not matching the reality, because Only a Lawyer would think it should.  And that is the actual problem.  It doesn't matter that climate models should only match the 30-year trendline, because what matters is what the Koch-funded lawyers think.  And that's where this battle must be fought, since lawyers, depending on who is paying, can argue themselves into thinking humans can breathe seawater.  And if you disagree, and can't, then you must not be human.

       @12...I guess you'd rather have automatic collecting instruments set to record any value regardless of how nonsensical it is without being further checked?

       It's really not a conspiracy to set limits on data collection instruments such that suspect readings can be validated no matter how much Jo Nova thinks so.

       ubrew - what model claim is to be able to predict is climate - ie 30 year weather averages and that they have skill in doing that. What they do not claim and have no skill at, is predicting decadal-level variation. Models have ESNO-like features but are incapable of predicting the size and timing of ENSO event even months out let alone years. On short term, ENSO dominates. On long term, you have climate and that is what models are attempting to predict. They should be evaluated only against the predictions for which they claim skill.

       supak @14, nigelj @20, Wallace may be an obscure engineer, but D'Aleo is a meteorologist, and Idso is a climatologist.  Both, however, are well known deniers, and Idso has earned a reputation for, for want of a better word, dishonesty when it comes to climate science.  Idso does not appear to have any peer reviewed climate research since the early 2000s, but has been very productive of misleading denier "reports".

       I have not gone right through the report but evidence in the early sections suggests this is just another in that sequence.  In particular, they show a graph of various versions of the GISS temperature trends (Figure IV-1), the differences between which they attribute to "adjustments".  The graph plots versions for 1980, 1987, 2007, 2010 and 2015.  Wallace et al, however, feel no need to inform readers that the number of meteorological stations used increased from 1000 to 2200 between 1981 the 1980 (actually 1981) and 1987 versions, or that it increased to 7200 for the 1999 version.  Nor do they feel any need to inform their readers that prior to 1995, no Sea Surface Temperature data was used, so that the data was for meteorological stations only.  The very substantial changes in the temperature series between "1980" and 1987, and between 1987 and 2007 are probably influenced by these large increases in available data.  Attributing the effect to "adjustments" without taking into account the change in available data is straightforwardly dishonest IMO.

       Hardly any better is the "proof" that the "adjustments" eliminate a large "cyclical" component by comparison of global temperature data to US and North Atlantic temperature data.  What is not noted is that the current versions of temperature data, even with all the adjustments, retain that large "cyclical" element in those areas. This can be seen clearly here, for example.  (I should note that adjustments have increased the trend of the temperature data for the contiguous US, but has not eliminated the "cyclical" pattern.  As a further note, I put "cyclical" in inverted commas because it is unclear to what extent the pattern is due to cyclical patterns in the climate, and to what extent it is due to changes in the aerosol forcing over time.)

       rocketeer @11 "Tiny corrections" to data can be a source of controversy in the deabate about climate change.  At Goulburn airport in New South Wales Australia, the recorded raw data for the minium temperature on Sunday July 2 2017 was -10.4C  This temperature was however adjusted automatically to -10.0C .  When the alteration was queried The Bureau of Meterology stated that temperatures below -10.0C are automatically moved to -10.0C.   The BoM did change the -10.0C value to -10.4C in the Daily Weather Observations page for Goulborn Airport but left the value blank in the Climate Data Online database, the database used to calculate regional, national and global temperatures.  Is this the way climate scientists should operate at the BoM?  Are maximum temperature cut off points used?  If so what are they?  Reports such as this serve to fuel the sceptical side of the debate on climate change

       scaddenp@17 quoted NorrisM@6: "The models did not predict this and therefore are unreliable."  Claiming that models didn't match 'reality' and therefore cannot be trusted, is like claiming that hands only have five fingers and therefore cannot be used.  You have the benefit of intellectual purity.  On the other 'hand', you are reduced to using your toes to grasp things.

       Supak @14

       I had a very quick scan through this research paper out of curiosity.  James P Wallace is some obscure engineer. It doesnt appear to have been conducted by climate scientists. I dont claim any specific climate expertise, but I take an interest, and the paper was easy to follow.

       The paper makes claims there are a lot of adjustments in temperature which accentuate a warming trend, that they consider suspicious and unwarrented. Maybe they are starting to see conspiracy theories. But they have to prove in meticulous detail why those adjustments would be invalid, and they just haven't really done this from what I can see.

       The most interesting and useful graph is fig1v-1 on page 11 which shows global temperatures, and essentially the very early data and  subsequent corrections. It is obvious that the raw data and corrected data since the 1970s is much the same. The real change has been early last century where data has actually been corrected downwards, which does lead to a stronger warming trend. But again the research paper haven't really demonstrated why that has been wrong.

       Either calculate some linear trends, or just step back and just squint your eyes down. The overall linear trends comparing the unadjusted data and adjusted data are just simply not hugely different anyway. We are still left with a strong warming trend, in even the unadjusted data. And they havent really proven why any adjustments are wrong.

       Now the research paper focuses a lot on America, but why would you do that? They are one country. Its better to look at global averages surely.

       The research makes a peculiar claim that in America "cyclical trends" have been removed or ignored. But they are making an unsupported claim that these are cyclical trends. We cannot say they are, and in fact all the evidence of global warming says they aren't.

       They also have a graph for my country NZ, which is really why I'm responding, and did have a quick read of the research. It got my attention obviously.

       Firstly the graph looks slighly wrong to me. But let that pass. We have recently had a big debate and enquiry as to whether adjustments to our data were valid, led by a certain sceptical lobby group. The bottom line is this became a big issue, involving a court case taken by the sceptical group against NIWA, our climate agency that prepared the temperature record and adjustments. The judge threw the case out of court, on the basis that the sceptical group didn't present properly qualified experts, and other failings.

       The temperature reconstructions were handed to an Australian climate agency to peer review, and they concluded there was nothing wrong with what NIWA had done and adjustments made were all in order. Refer link below:

       "Many Republican policymakers will now admit, like Perry, that humans have “some impact” on the climate. That simply represents an acceptance of 150-year-old science. They don’t deserve much credit for finally accepting science that was first established when John Quincy Adams was president."

       And the understanding that something was making the Earth warmer that it would otherwise be if it re-radiated directly the all energy back into space that it receives from the Sun goes way back to the late 1600s.

       The Trump administration and many republicans are stuck way back in the Middle Ages on this topic when many people believed in succubi and succubuses and such things. Then again maybe they still believe in those things as well.

       Taking an anti-information position can not and will not work in the real world.

       Contributing my 2c.

       "The models did not predict this and therefore are unreliable."  This is a rhetorical trick - a straw man. Models have no skill at decadal prediction, never claim to. If you look at individual model runs,

       

       pauses are not uncommon.

       Going back to early times, I think republicans had a visceral response to AGW from combination of sounds expensive/more govm't/less freedom/Al Gore is fat. From there it is look for reason to discount it. "Climategate" gave one. I would suspect 99% read the damaging attacks from denialists and believed them as confirming what they suspected without making any effort to seek out context despite climate scientists almost immediately providing that context. Investigations of course did look at context and exonerated the scientist but I doubt many read the detail, preferring to claim whitewash/cover up.

       Why are US and particularly GOPers so locked in denial? More interesting question. To me it seems "critical thinking" skills are completely lost. I wonder whether there is a deep distrust in teaching critical thinking least it lead to atheism? The red/blue team idea seems to indicate a strong tendency to legal thought and process rather scientific.

       NorrisM @12

       Thank's for clarifying your views on Trump and Pence. I was probably a little unfair to have suggested you were being disingenuous. It was just impatience on my part.

       Just briefly on the issue, because I'm more interested in the red, blue team issue. I have the same reaction, Trump is scary, and Pence is too ultra conservative for me and particularly regarding religion. I could much more easily accept someone like Reagon.

       I'm also not impressed with politicians who just make things up, and while they are literally all guilty of this, and none of us are perfect, Trump is in a class of his own.

       When people cannot even agree on basic facts, theres nothing left but fighting and tension, or even all out civil war.

       However I would prefer Pence by a small margin. I have real concerns that Trump could start an unnecessary war, and this is the greater concern for me living in NZ, as such things have global implications outside America, either militarily or econiomically, so Pence seems preferable from my own admittedly self interested perspective. But surely none of us want a war? Especially another war that literally doesn't make sense.

       I have mixed feelings about Trump surviving the first term. It would be hard to impeach him, although moves have already started in earnest. The Russia thing is a mystery, and I would not like to guess an outcome. Perhaps Trump is teflon coated like certain other presidents, and it's common with shrewd politicians, but he is so mired in so many scandals that there's quite a high probability he might not survive the first term.

       I doubt he will be re-elected unless his attitudes change. Republicans have no love for him. However much may depend on the economy, as this determines politicians fates more than anything.

       I'm still very sceptical about your red blue team. I suppose if it produces more funding that would be nice. JW Rebel has raised some good points.

       I would do as you yourself say in general, and "step back and look at the issues from the outside". The scientific community are unlikely to take the red blue team seriously as its just a smaller version of the IPCC, and set up by people with a very strong hatred of climate science, so hardlly objective people. The rest of the world will see it as a jacked up joke of a process, that may be biased and untrustworthy. The Australians would call it a sort of Kangaroo Court. So whatever the result, it is likely to have poor credibility. And who would be on the panel? It will be hard to find exemplary people, and if its staffed with numerous sceptics it will be considered a joke by the rest of the world.

       I think Tom Curtis made a key point about sceptics. Yes, I would accept climate scientists like Michael Mann are not perfect. The last IPCC report had a mistake about Himilayan Glaciers, (one mistake in a document over a thousaand pages long, and not actually remotely crucial to basic climate theory). This stuff gets enormous publicity, but rarely does the so called "media" do a review of the numerous mistakes made by "sceptics" and believe me they are numerous. 

       So yes what might ultimately count most is the substance of someones ideas, we should never forget that, but one side in this debate has far more general credibility, and its not the sceptics. But the mass media are corporate owned, and have done a cynical and I believe deliberate job protecting the sceptics from any real scrutiny. 

       Sceptics are always sure they are right about everything and never admit uncertainty, ever. Have you noticed this? They do come across like lawyers. In comparison the IPCC meticulously documents varying levels of certainty across varying things.

       Ultimately the sceptical campaign is a huge delaying tactic.

       About Olivine. 
       Indeed there is NO silver bullet. So we need to reduce CO2 emissions, but also remove CO2 from the atmosphere.
       -1- So solely counteracting all of the global CO2 emissions with solely olivine is not a good idea.
       -2- There is more and more research available. See i.e. this open access article from Francesc Montserrat (and myself ;-) )

       Why the Republican Party's climate policy obstruction is indefensible
       

       1. The only honest climate "sceptics" are those who are rather unfamiliar with the material: people who out of some sort of misguided ideological loyalty to their group or tribe think that it is another left-wing progressive government ploy, out to destroy traditional values, work, and families. The rest are being disingenuous at best. Those who are taking a group position may be open to changing their minds under the right circumstances, probably not by learning about IR-bands and CO² molecules, but by appeals to their loyalty and conservatism which mandate not running down the farm before handing it over to their children.
       The others are not well-intentioned or well-meaning people.

       2. Just because 97% of [climate] scientists have stated that anthropogenic climate change is real does not mean that the other 3% have good theories and other data sets showing the opposite. Far from it. That would mean there are a lot of bona fide scientists with reasonable alternate theories whose research and credentials are impeccable. That is not true: finding sceptics that you can parade around as "real" scientists is like searching for a needle in a hay stack. That is why you keep meeting the same very small handful of star-status sceptics, none of whom are close to producing some synthesis of theoretical grounds on why the data has not been interpreted correctly and can be better explained by their alternative.

       3. Staffing a red team (Richard Muller is no longer a candidate) with qualified specialists is therefore pretty much mission impossible. It's like equipping moderate "rebels". After ½ a $billion there were 5 rebels, who immediately passed their equipment on to the other side to which they defected at the first encounter. Educating new candidates for your red team would be like cupping some sea water and crossing the entire beach — they would be convinced by the material as soon as they started understanding the efforts and results undertaken so far.

       4. If there were qualified scientists with convincing alternate explanations of the facts, they could make a killing$. Such a person would be herded into every studio and corporate office around.

       5. The whole sceptical delusion is a disorder that only seems to occur in a select group of Anglo-Saxon countries, much like an infection, mainly due to patterns of media ownership and corporate funded think tanks and lobbyists.

       >> Only rhetorical and political considerations remain. It is time for investments in energy alternative and research in the same order of magnitude as military spending: this is one war we cannot afford to lose. People on the wrong side of this issue have to be outed as dummies, fakes, mercenaries, nincompoops, malevolent charlatans, hired ideologues, whores. None of the talking points are remotely plausible for anybody who takes the time to look into the actual science and responses by scientists. People who raise the "talking points" need to be pointed in the right direction once or twice, but any sign of perseverance means it is willful stupidity.
       Against the foolhardy even the gods contend in vain.

       Why the Republican Party's climate policy obstruction is indefensible
       

       NorrisM@6 said: "ClimateGate had a very damaging effect... It is very similar to evidence given by a witness testifying in some legal case... For any jury, ALL of the evidence of that witness is tainted."

       I'm constantly amazed how often climate deniers use the Law as an example to Science.  Who has a more questionable reputation, lawyers or scientists?   Next time I see a scientist chasing an ambulance I'll revise my opinion.  For example, deniers keep harping on the exact timing of the demise of the Arctic summer sea ice.  It is apparently really, really important to them that the scientists accurately predict the exact year when Arctic summer sea ice disappears.  Who, other than a lawyer, performs this kind of misdirection?  Hey, prosecutor, 80% of the sea ice is already gone!  Past tense.  In the last 30 years.  Outside a courtroom, is there any question where the remaining 20% is headed?

       Those of us fighting what is going on need to be aware that we are fighting rooms full of lawyers, and their speciality is misdirection.  A favorite is 'moving the goalposts': like suddenly its no longer sufficient to point out that 80% of Arctic summer sea ice is gone, scientists must now predict exactly when the remaining 20% will be gone or their reputations will be ruined, their testimony tainted, and climate denial justified for the rest of eternity.  

       The appeal to jurisprudence is how NorrisM can point to the 'hiatus' and render judgement, "The models did not predict this and therefore are unreliable."  But barrister, outside the kind of courtroom that found OJ Simpson guiltless of murder, any model of reality fundamentally cannot beat reality.  It's not possible.  It can only beat other models.  It's not the fault of scientists if the Heartland Institute won't produce any.  What you really should be asking yourself, NorrisM, is: 'Why won't they?'.  That would at least lead you to a constructive outcome.

       Why the Republican Party's climate policy obstruction is indefensible
       

       nijelj and Tom Curtis.  Thanks, some very interesting replies. 

       As a non-scientist (and Canadian) I am just trying to get a handle on a very important issue looking on from the outside given that the main battleground is in the US.  Please be assured that I think that the election of Trump is one of the scariest things to happen in my life.   My concern is that everything that I have read and listened to (Sam Harris podcasts especially) tells me that we have Trump for a long time unless evidence is uncovered showing that Trump personally colluded with the Russians.  But all that means is that we end up with Pence as President.  Given my views on religion, this is just as scary a prospect. 

       So my point is that a "new" red team blue team is about the only thing that I think the Republicans will undertake.  If this ultimately gets more money for observational equipment, then that would be a positive.

       Funny how the 'climate science deniers'  (I like this term because it clarifies exactly what they are denying) get so upset about the tiny corrections made to the surface data (i.e. Karl 2015) but think the satellite data is incontrovertible, despite the major revisions made every few years.

       Why the Republican Party's climate policy obstruction is indefensible
       

       NorrisM @6 ,

       regarding the APS (American Physical Society) workshop/review of global warming [carried out in January 2014] and its 500+ page transcript (fortunately each page is brief!!!) :-

       I have read through the transcript, with particular attention to the sections which you highlighted (in another thread) as showing dubious science and/or dubious answers/fudging ..... and I must say I found nothing substantive there which could be taken as overthrowing the mainstream science.     Nothing at all.    So I must beg you to be specific in nominating and clarifying any points which you feel strongly could support the denialist position (other than points of sheer empty rhetoric — of which there were many!!!!).

       And in support of my statement above : it comes as no surprise that the senior officials/scientists/physicists of the APS found nothing substantive enough to justify them altering the APS Statement on AGW and climate science.

       Furthermore, you will have noted that the review panel workshop date was January 2014 : just before the 3 record hot years 2014 / 2015 / 2016 (plus year-to-date in 2017) gave added demonstration of how empty and unreal were the claims that Global Warming had stopped.   On top of that, the accompanying tropospheric warming now shows Christy's own claims to be wrong.  And also reinforcing that Lindzen is very, very wrong.

       Tom Curtis and Nigelj have indicated the false reasoning i.e. "motivated reasoning" used by many science-deniers such as Koonin Lindzen Christy and Curry.  It must be highly likely that Curry's claim that "Climategate" suddenly converted her away from mainstream science ..... is a factitious claim made in retrospect : a demonstration of "motivated reasoning" on her part.  After all, numerous independent reviews have shown that the "Climategate" allegations were a beat-up over nothing substantive.  And what real scientist would alter her views, citing evidence known to be false?!

       That is why the Republican politicians' professed desire for "Red Team" reassessment, is pure poppycock.  All they wish to do is achieve further years of delaying tactics, and at the same time give the public the impression that the genuine climate scientists are sufficiently moved by doubt of their own position (as to agree that review is necessary).

       Here is a direct comparison of the new RSS TLT record and the RATPAC-A record based on weather balloons with real thermometers. The latter is an average of the four altitude levels 1.5, 3, 5.6 and 7.2 km. The two records use different base periods, but that doesn’t change the fact that their trends are very similar after the RSS update.

       Why the Republican Party's climate policy obstruction is indefensible
       

       Norris M @6

       Interesting comments, but I largely disagree.

       "Rightly or wrongly, I think that ClimateGate had a very damaging effect on the climate change views of conservatives everywhere. "

       Well it probably didn't help their views. I  can appreciate that much. 

       People do get tainted by one so called mistake (alleged in the cause of climategate), but that is very shallow to dismiss people on that basis.

       It's also very much "wrongly" that climate gate tainted anyones views. I'm a political moderate, with a reasonably  decent arts, technical and some science education. It only took me five minutes reading the actual evidence of climate gate and both sides of debate and commentary, to see there was literally nothing there, nothing wrong. Numerous investigations have also concluded the same.

       People concluding otherwise, must want to conclude otherwise, and are being irrational. I do however agree it was an unfortuante thing and rather bad luck, but to claim it means the damage is irreversible is absurd, innacurate and lazy thinking.

       "Judith Curry has herself admitted that this made her seriously question her position which was until then "mainstream"

       Her views are in a small minority of climate scientists, and she does not have a spectacular research record or any great clarity on anything, in fact she is rather vague about things. So please explain why you give her views prominence.

       "The hiatus"

       So much rubbish is talked about this. Firstly the latest information shows the pause was more of a short blip, and entirely within expectations. Last years temperatures changed everything.

       It's at least partly  inaccurate to claim models didn't predict the pause. All models without exception expect flat periods, but its impossible to predict them exacly because short term natural variation is slightly random. Models have been reasonably reliable predicting temperatures, as evidenced by articles on this website.

       Things are still slightly under predictions, but only slightly and this is not enough to be concerned about. Republicans dont appear to want to hear that, instead they seem to hear, things are not 100% as predicted to within millimetres, so everything must be wrong. With respect this is childish, self interested, and intellectually empty thinking, and they are smarter than that.

       "For now let us not get into arguments about this because you will NOT convince the Republicans by one "new study" that shows that the IPCC was mistaken. "

       So you are saying don't even try because people are so stubborn with minds closed? Humanity might as well give up. Just imagine your outrage if Hilary Clinton said something like that. Nobody needs to be that closed minded.

       Remember the only evidence that really counts is the science, and weight of scientific evidence, and it all points one way. Not politics, or character of climate scientists, or scandals, or occasional mistakes, or the like. One mistake on a minor point does not make an entire theory wrong, or key conclusions wrong. Climate change theory is built on wide evidence, not one piece of evidence.

       "So "97% of climate scientists" does not cut it with Republicans. They simply do not trust the climate scientists believing, rightly or wrongly, that their bread and butter is really based upon making sure that climate change is primarily man-made."

       Well that is just foolish thinking. Scientists are not exaggerating to manufacture work. Scientists get work in all sorts of fields because its needed, without glamourising everything.  

       We could turn around and say we dont trust politicians because their bread and butter depends on xyz, or business people or anyone. The world cannot and doesn't work like that or it would come to a complete stop . You have to have fundamental trust in professionals, unless they personally start to consistently act otherwise. Now look at the many, many false claims by Donald Trump, and there you have someone of dubious integrity.

       Basically people just do their jobs, and scientists are no different. They very critical of each other if they can find fault, because its in their interests. 

       "Can anyone really be a scientist and say that 100% of climate change is man-made? "

       Obviously yes, if thats what the science finds, and it does or very close to it. It's like certain diseases have very precise causes.

       "Climate change has been on-going for the life of the planet and the man-made CO2 emissions simply cannot be 100% unless you have strong evidence that we are in a natural "cooling period". "

       There is overwhelming evidence that we are in a natural cooling period. The solar energy output of the sun has been in a decades long cooling phase. Review "Is it the sun" on this website. This is a key reason for scientists beings concerned, quite apart from the evidence and calculations that point at CO2.

       "It is not possible that the climate naturally is not going either up or down. "

       No because the science doesn't find this. There are over 12,000 research papers on climate change, and many look at this aspect. How many would be enough for you?

       "When you say "100%" you sound like an extremist. Most people, and especially conservatives, do not like extremists. Not a smart thing to say."

       Maybe so, but when they said 90% that was too extreme as well. Seriously do we have science here, or "pc" correctness on an acceptable level? What is an "acceptable level" and why? 

       "But back to the Republican position. When they see there are real-life climate scientists like Judith Curry (who I have to admit sounds much more balanced than Michael Mann in testimony before the various Congress committees and who is not subject to any "ad hominem" attacks that seem to be levelled at Christy and Lindzen),"

       With respect, you are being one eyed. There's fault on both sides. Michael Mann gets abuse each week for example. Forget the short tempers, and look at the scientific research.

       "then the "red team blue team" approach with other scientists (primarily physicists I hope) may be the best answer to the Republicans"

       It's a staged, dubious sort of enquiry that can achieve nothing new. It's too small. The IPCC is much, larger and they include sceptics as well as so called warmists, and rotate new scientists on each review panel. You have a very good process, but most people haven't read what really happens overall, only biased little snippets of information taken out of context.

       The rest of the world has moved on while the Republicans alone seem stuck. You are just engaging in delaying tactics yet again, and we are sick of it for over a decade now. The rest of the world has seen through the ruse, and moved on to accept the obvious reality of human caused warming.

       "Once we get past what Dessler calls "positive statements" (in his very good book on climate change)"

       It's a very dubious book, and it's not about books and opinions, it's about the weight of published evidence in proper journals.

       "I just think the climate science community has to do a reality check. Trump won and he in all likelihood is here for at least for the remainder of his first term and possibly 8 years (would Pence be any better?). "Anyone who does not accept this is really like the ostrich in the sand pictured on the home page of this website."

       That's a real laugh given Trumps approval ratings are so low. I doubt he will even survive this term, and chances of re-election look slim. I'm sorry he is probably a good family man, but imho he is a confidence trickster, and does not have solidly founded policies and beliefs.

       "I personally am very unhappy with this situation but the American people have spoken!'

       Yeah sure. All your previous comments suggest otherwise. 

       "Churchill has noted, democracy is close to unworkable but compared to the alternatives, it is the best. "

       Well I would agree on that, but not with much else.

       Why the Republican Party's climate policy obstruction is indefensible
       

       NorrisM @6, while I agree that "climategate" was damaging, your analysis does not give the reason. 

       In the first instance, while the climate scientists may have used a poor choise of words in several (among many thousands of) emails, multiple independant investigations showed they had done nothing wrong as regards science (one was guilty of trying to avoid Freedom of Information requirements).  This is even demonstrable on the public record, with the most damaging accusations being that the scientists "hid the decline" whereas they had discussed the decline in late twentieth century tree ring widths (ie, the decline in question) in multiple publicly available scientific papers.  Several more damaging accussations were complete fictions; ie, the people making the accussation were involved in fraudulent behaviour in making and presenting "evidence" for the accussation.

       Secondly, even if the scientists in question had been guilty of scientific misconduct, they represented a handful of scientists among literally thousands of climate scientists.  In almost all industries, cases of misconduct will rise well above the approx 1% level that would imply.  The people rushing to condemn climate science do not typically condemn those industries of dishonesty on that greater basis, so it is not true that they are condemning climate science on that much smaller sample.

       Thirdly, the climate "skeptics" in general, and nearly all of them in particular, have been guilty of demonstrable dishonesty or sharp practise on a regular basis.  So much so that it is difficult to find a single "skeptical" paper in recent times that does not involve blatant misrepresentation of either what others have claimed, basic science, or observed facts.  This far more wide spread dishonesty has not resulted in a general distrust of climate "skeptics", or their positions.  Therefore they have not rejected climate science because of the purported dishonesty of climate scientists.

       The second two points rely on a fundamental of causation, ie, that like causes have like responses.  This is a factor in reasoning.  If we do not trust x because of circumstances, y, then we will also not trust x' if an exactly similar set of circumstances, y' applies.  The exception is with motivated reasoning.  That is, when we do not trust x because we do not like the message they give, but we asribe the mistrust to circumstances y to give a cloak of rationality to our mistrust.  If we then come across x' who gives a message we do like, even though exactly similar circumstances, y' apply, we will trust them because the actual reason for our distrust was the dislike of the message.

       To be honest, most conservatives are probably not that direct.  They may reject climate science simply because Pravda on the Hudson (ie, Fox News) does so, which they in turn trust because of motivated reasoning; while Fox News gives great, and very distorted prominence to "climategate" while concealing the many distortions of their regular contributors on climate.

       The same motivated reasoning applies to rejection of consensus messaging, as it implicitly means accepting Scott Westerfield's far more implausible "plot idea":

       Noam Chomsky talks plenty of sense. His book "Who Rules the World" is a recent  introduction to the full range of his views, and chapter 11 the doomsday clock covers climate change and nuclear issues. He also discusses neoliberalism.

       This guy has some "new deal" leaning economic views which I partly agree with, but some dont like. I suggest put economic ideological bias aside. His main points are more related to political values and foreign policy, where he is just asking that America be consistent, that they apply to themselves and their own government the rather high standards they demand of everyone else. 

19036. NorrisM at 16:31 PM on 6 July 2017
       Why the Republican Party's climate policy obstruction is indefensible
       

       Rightly or wrongly, I think that ClimateGate had a very damaging effect on the climate change views of conservatives everywhere.  It is very similar to evidence given by a witness testifying in some legal case who is  completely honest in his testimony until the last question, where, in his desire to "win the case" for whatever side, he  "fudges" his last answer.  The cross-examining lawyer then leads another witness who proves on that very point that the witness was not telling the truth.  For any jury, ALL of the evidence of that witness is tainted.  I truly think this happened with this issue.  Judith Curry has herself admitted that this made her seriously question her position which was until then "mainstream".   It is just about irrelevant now as to what was or was not the intention of those emails.  The damage has been done.  End of story.

       When you add this to the issue of the "hiatus" of X number of years whether or not it was really there (the IPCC at least in 2013 coined that term) has added to the legitimate questions of conservatives that are we being led down a garden path.  The models did not predict this and therefore are unreliable.    That is not an unreasonable position to take IF the hiatus really occurred.  For now let us not get into arguments about this because you will NOT convince the Republicans by one "new study" that shows that the IPCC was mistaken. 

       Then you add on John Christy's famous graph which so impressed Steve Koonin between the predictions of the models and the actual observations (see APS panel hearing below).  Do you not think that those pressing the Republicans not to do anything on the climate change file have not read the transcript of the APS panel hearing where three (3) of the top IPCC contributing climate scientists, Collins, Hand and Santer, admitted that the model predictions do not track the observations?  Their answer was that they do not trust the observations.  Can you not see how this would make conservatives suspicious?

       So "97% of climate scientists" does not cut it with Republicans.  They simply do not trust the climate scientists believing, rightly or wrongly, that their bread and butter is really based upon making sure that climate change is primarily man-made.  Can anyone really be a scientist and say that 100% of climate change is man-made?  On  that point I fully agree with Perry.  Climate change has been on-going for the life of the planet and the man-made CO2 emissions simply cannot be 100% unless you have strong evidence that we are in a natural "cooling period".  It is not possible that the climate naturally is not going either up or down.  When you say "100%" you sound like an extremist.  Most people, and especially conservatives, do not like extremists.  Not a smart thing to say.

       But back to the Republican position.  When they see there are real-life climate scientists like Judith Curry (who I have to admit sounds much more balanced than Michael Mann in testimony before the various Congress committees and who is not subject to any "ad hominem" attacks that seem to be levelled at Christy and Lindzen), then the "red team blue team" approach with other scientists (primarily physicists I hope) may be the best answer to the Republicans.  Give it a go and see what happens.  If the Koch Bros result happens again, then you will have a very legitimate and strong position to force the Republicans to act.  If their own "red team blue team" comes to the conclusion that CO2 emissions are really the cause then we are at least then only into the question of how much warming and decisions as to how best to approach this.  So I say, fully support the "red team blue team" even if it has been done before. 

       Once we get past what Dessler calls "positive statements" (in his very good book on climate change) which are the facts, then we can get into "normative statements" on what we think the results are in economic terms and what we should do about it, both as to mitigation and adaptation.

       I do suspect that such a "red team blue team" debate will get bogged down on the facts and largely because we do not have the proper instruments to measure what is happening year to year.  If the result is that the Republicans do at least decide to dedicate much more money to funding both weather/climate satellites and water buoys and on-land temperature measurements then it will be a "win" for the majority of climate scientists who believe that we are the cause.

       What I found most unsatisfying about the APS panel struck in 2014 to re-evaluate their statement on Climate Change is that after having somewhat of an "appellate hearing" there were no "reasons for judgment", just a decision by the Board of Directors of the APS one year later to effectively stick with their previous statement.  I have no problem with them sticking with their same statement but by providing their reasons they could have provided massive "independent evidence" outside the climate science community that man made warming is a major threat to our world.  On another post, I have made reference to the APS panel.  You can read the APS Workshop Framework Questions and transcript of the proceeding with 6 of the top climatologists on both sides of this debate on the APS.org website just searching "Climate Change Policy Review".

       I just think the climate science community has to do a reality check.  Trump won and he in all likelihood is here for at least for the remainder of his first term and possibly 8 years (would Pence be any better?).  Anyone who does not accept this is really like the ostrich in the sand pictured on the home page of this website. 

       I personally am very unhappy with this situation but the American people have spoken!  Get used to it!  As Winston Churchill has noted, democracy is close to unworkable but compared to the alternatives, it is the best.  Comey must stay awake at nights realizing how he might have turned the course of history.

       The New York Times has published an email based interview of Noam Chomski. The interview presents an interesting perspective on Team Trump and who the supporting trouble-makers really are (spoiler alert - it is not Russian Hackers attempting to rig the election).

       An interesting point made is that Climate Change and Nuclear War are Noam's top identified concerns (and it is hard to argue against that) with the current USA leadership and its supporters being the major concern related to those two concerns (also hard to argue against).

       It is deplorable when someone who does not have the capability to understand complicated important matters gets promoted to the level of their clear incompetence (the Peter Principle). It is more deplorable when that person's boss is as incompetent at being the Boss of that role.

       Rick Perry first claimed he was a skeptic then proved that he was not a skeptic. When faced with something that doesn't sound reasonable a skeptic would say they will have to investigate the matter to better understand it and promise to return with an honest response after achieving a better understanding. Rick Perry did not do that regarding the best explanation of what has been going on as presented by the Lead Scientist on the BEST Team.

       So Rick Perry showed that he was incapable of investigating, or unwilling to investigate, a matter to be sure he understood it. That makes him undeniably incapable of properly performing the responsibilities of his appointed leadership role. He should be removed from the role and b required to take training and pass tests to prove he has developed the required capabilities before getting a similar role. If he tries to excuse his statement and claim he actually did know better then he is worse than incompetent and should be penalised in addition to being removed from his role.

       What I have presented above regarding Rick Perry applies in properly Lead Businesses and Governments.

       The fact that Trump has not removed Rick Perry from the role he has proven his lack of ability to properly perform should be adequate proof that The Boss is also not capable of properly performing the duties of the President.

       Bad news for climate contrarians – 'the best data we have' just got hotter
       

       Jeff T@7,

       Initially I wasn't certain about what you were referring to, so I checked the graphs.

       It appears you are commenting on the trend line shown on the "Major revisions upward after 1998" graph. That graph compares the trends of the data since 1998 for the correction of interpretation of the satellite data.

       The trend of the entire RSSv4 TLT data set is shown in the lower graph labelled "Satellite temps warming faster than surface". The trend line of the entire data set is less than 0.2 in 1998 and nearly 0.5 at the end (2016/17). The trend line in the earlier graph that starts in 1998 is above 0.2 in 1998 and clearly below 0.5 at the end.

       So the trend of the overall data set is actually a more rapid rate of increase than the rate from 1998 to today.

       And I agree, deniers would attempt to claim something similar to what you thought you had discovered and hope that people will 'like what they hear and not bother to check if what they want to believe is actually valid'.

       Bad news for climate contrarians – 'the best data we have' just got hotter
       

       DrivingBy @5 and Nigelj @6:
       The satellites providing the data used by RSS and UAH are not 20,000+ miles above the Earth, but only about 800 km (~ 500 miles), roughly twice as high as the International Space Station and orbit the Earth every 100 minutes or so.
       Maybe you were thinking of the geostationary orbit (35,800 km / ~ 22,000 miles) used by the communication satellites? If these satellites really were that high up, they wouldn’t suffer from the tiny atmospheric drag that still exists a few hundred kilometres above the Earth and causes the orbits to change over time.

       I think the RSS TLT record is reasonably accurate now, not only because it agrees pretty well with NASAs surface record (the second graph) but also with lower troposphere measurements by weather balloons with real thermometers in direct contact with the atmosphere.

       John, thanks for the explanation of the RSS changes and your many other efforts to encourage action on climate change.  One complaint though: the graph that compares old and new RSS data shows trends since 1998.  The trend lines were clearly computed by ignoring data prior to 1998.  Consequently, there is an implicit discontinuity of temperature in 1998 that makes the trend steeper than it ought to be.  Skeptical Science has correctly faulted people like Christpher Monckton for similar calculations.  Please make it clear in the text that you don't consider it proper to ignore some of the data.

       Why the Republican Party's climate policy obstruction is indefensible
       

       Republican politicians tend to have been in business or have ties to the business sector. They have been responsible for large corporations, or managing other peoples money, or are contracted to produce results and profits, and maybe they see climate science as threatening to that and their friends in the business sector. 

       But thats not really an excuse to deny basic science, or irresponsibly damage the environment, or promote dubious modes of business behaviour. Clearly plenty of executives have acted unethically at times, for example the GFC exposed this. Politicians deregulated the business sector, and created an environment conducive to unethical behaviour. We the public should not have to put up with any of this.

       Making a profit is not a reason to cut corners. The rest of us have to do our jobs correctly and within ethical guidlines, and various rules, so the same should apply to everyone. Nobody is above the law, or simple ethics, and responsible behaviour.

       I'm pro business, but voters are stupid if they keep voting for parties that over protect the business sector.

       It would be great if the Republicans (and a large part of their voting base) just took a deep breath and look at examples like Vovo Car's, who clearly accept the problem, given they are moving to 100% production of electrics and hybrids. So their ceo, executives, owners and managers clearly have a different attitude to the envionment than the Republican Party. Maybe they are just smarter business people as well, and see the writing on the wall.

       Driving by, yes true in your first half on corrections. Very clever point.

       The surface data is more important as we inhabit the surface , but I think climate scientists consider satellite data important because most climate models (but not all) expect 25,000 miles up would heat slightly more than the surface, and this would be a strong sign of the greenhouse effect. the latest data does appear to confirm this. It's something to do with how the lapse rate works.

       Here's another fustration on corrections, regarding surface temperatures, the denialists say its all due to "urban heat islands" and then the data is adjusted to ensure this effect isn't biasing temperatures upwards, and then the denialists say "you fiddled with the data". You can't win with these people. It's like falling into a river full of piranah fish.

       Wouldn't it be helpful to point out that satellites

       • Are 20,000+ miles above Earth
       • Do not have thermometers.  
       • Don't measure the temperature where stuff lives.

       A theromometer on a satellite would just measure the temperature of space. I suspect most denialists have no clue about that, as they do a copypaste of bullet points they've seen somewhere.  If they whine about 'corrections', then give them the raw (microwave sensor) data and tell them to interpret it themselves, but accurately.  Then if they just translate microwave sensor raw to temp, it's "wrong, you didn't calibrate". If they do calibrate, come back with "you just used corrections on the data". 

       But more to the point, note that they're looking at an air mass far above ground that's partly insulated by the greenhouse effect (it's blocking some of the ground's IR radiation). If if you can process the EMR sensor data (microwave sensor, iirc) from 25,000 miles up into an accurate temperature, it doesn't look at the ocean temp (90%+ of surface heat) OR the ground level air temp.  So the question could be "Why are you looking away from the thing we're talking about (ocean+surface) and staring into space?

       Planet Hacks: Flying
       

       I do much of my holiday travel with Google Earth Streetview.

       It's less than perfect but is cheap, I don't need to leave my home and chair, and I don't have to put up with other passengers and cramped seating.

       More seriously, for several years I and others have been trying to introduce virtual meetings via Skype to Rotary Clubs and the many committees that they spawn.  Progress has been slow, but at least the legislation in NSW, Australia was amended a year ago to enable electronic attendance at meetings.

       Just some comments.

       • The figure of 30 billion tonnes a year. I have done a rough estimate that all mining and quarrying activity is around 100-150 billion tonnes a year, so a significant increase.
       • Then all of that needs to be crushed to reasonable fineness. Currently of that 100-150, only part of that is crushed, mainly mineral ores, so possibly doubling world crusher capacity. And crushing is energy intensive. So a substantial expansion. Obviously all this would need to be powered from renewable sources.

       So all in all a huge undertaking.

       Next, I would want to see a lot more research into consequences in the oceans, that paper is rather light on that topic but it may be the make or break issue. Although they are right about the basic chemistry there is a lot of scope for unintended consequences for the biosphere in the ocean.

       Imagine we have spread a couple of 100 billion tonnes, then we discover some unexpected bad consequence in the oceans. Once the dust is scattered that is one very hard Genie to put back ino that bottle.
       
       So I think this idea needs to be explored very strongly, but it is very preliminary at this stage.
