  1. BEST Results Consistent with Human-Caused Global Warming
    Excellent post. Should be a must read for anyone still open minded about the extent of human impact on the climate. And regarding that, the discussion of what levels of CO2 is "safe", related of course to prevent some catastrophic breakdown in the biosphere, atmosphere, and ocean systems supporting both humans and other creatures, what is absolutely critical here is a wholistic approach-- true Anthropocene Management. Increasing CO2 levels are just one of the many ways humans are altering this planet, and have been for many centuries. In a wholistic approach, we would look at not just CO2 but land uses, methane, the nitrogen cycle, water use, etc. Thus, while it might be good to pick a general target of CO2, at say 350 ppm, it should be part of an overall Anthropocene Management effort that looks at all the ways humans alter the planet of which controlling CO2 levels is just one aspect. My bigger fear related to this is that things will get out of control faster than most might imagine, leading to ever greater instability in governments and societies around the world. You might see reactionary governments come to power who have no interest in climate control or the instability might cause some to "go it alone" in terms of attempting to geoengineer the planet. We could have geoengineering efforts that end up doing more harm than good. It would be like having 10 different doctors independently treating a patient without any consultation with each other. This all could be very counter productive of course.
  2. Watts' New Paper - Analysis and Critique
    Trent1492: one way to refer to a paper is by the author(s), and the year it was published. see for example the reference to "Schaal et al. 1977" in the article. in this case, Bernard is implying that they're somewhat jumping the gun when they assuming that 5 months will be sufficient to get this particular mess into a publishable state.

    IPCC is alarmist
    Krisbaum's difficulty in obtaining reliable information is transparent in others of his unsupported statements: "it is fairly common knowledge that aerosols do not travel far from their source typically 10km or so. You need localised measurements to get any kind of global pattern." This assertion is not supported by any scientific reference in the post. Anyone looking at a satellite picture of China's dust traveling over the Pacific will come to the conclusion that saying "10km or so" is so removed from reality as to indicate deep ignorance of the subject. Earlier Krisbaum was mentioning the lack of a historical depth to the science of atmospheric aerosols. If one does explore the subject, however, one of the first things to be found is 19th century research centered on studying the reports of ships receiving dust from the Sahara while thousands of km away in the Atlantic. Not 10 km, thousands. This remains a common occurrence, that can easily be seen on satellite pictures. On this one from NASA, the dust crosses the entire Atlantic: http://earthobservatory.nasa.gov/IOTD/view.php?id=44169 Th entire Atlantic, not 10 km. It should be noted that this is dust picked up from the ground, not injected directly in the stratosphere by a volcano. How quickly that latter type travels around the world has already been studied extensively. I do not believe that it is even necessary to post any reference on that, as it takes only a few seconds on Google to find an entire list. The picture of Saharan dust above took me less than 10 seconds to find. In light of this, it is safe to say that this statement: "it is fairly common knowledge that aerosols do not travel far from their source typically 10km or so" is total nonsense that can not possibly form in the mind of anyone actually trying to get information on the subject. Now, let's examine this: "You need localised measurements to get any kind of global pattern." There is a contradiction of terms in the first place, but let's consider that what was meant was something like: you need many, gridded local measurements to get etc etc. It still makes no sense. Aerosols that do not reach the upper atmosphere have no global climate influence. The impossible-to-pronounce- Icelandic volcano that disrupted air travel not long ago did not create a real forcing because aerosols did not go high enough. Having a local record will tell only how some aerosols could have affected that local area. Records from Greenland, where there are no local sources, show the amount of well mixed aerosols, that are present in the atmosphere at large and can be a global forcing.
  4. Watts' New Paper - Analysis and Critique
    @Bernard J, What does calling this paper "Watts 12" mean?
  5. Debunking Climate Myths from Politicians
    John B - the Great Barrier Reef may be entering a time of great danger. Not only is ocean acidification bubbling away in the background, but a return to an El Nino-dominant period will probably bring on mass coral bleaching. Not good for a reef already losing coral cover year-by-year due to pollution, disease and crown-of-thorns outbreaks. You'd expect an Environment Minister to be.....concerned about the environment.

    Micheal Sweet maybe explain how you come to the conclusions that you have written above??? it looks like a lot of opinion to me....

    Unprecedented Greenland Ice Sheet Surface Melt
    I did get a response back from Dr. Box agreeing that Greenland surface melt "150 year cycles" should be looked into. He further added that the 1 degree C summer temperature increase in the period of instrumental observations, continuous for west Greenland since 1840 (173 years), make melt episodes more likely. As an FYI, Dr. Box has a blog post update of relevance, here: http://www.meltfactor.org/blog/?p=677. In which can be found this excellent graphic: The warming of the GIS during the 1930's is notably less than that warming being experienced by the GIS today.

    IPCC is alarmist
    Krisbaum, It is difficult to discuss the IPCC with you because you appear to have no understanding of how the IPCC works and what its intended goals are. The Intergovernmental PCC was formed to inform the world's governments about the possibility of climate change. As such governments choose the experts who write the reports. Who do you suggest would be better to choose the experts- you? Your suggestion that someone else should choose the experts is absurd, there is no-one else who could choose them. In any case, if you do not like the experts chosen you can complain. While I have not heard of anyone replaced because they were complained about I would be surprised if no-one has been removed from a position. The experts include scientists from the oil industry. I am astonished that you complain that an expert had only earned his PhD two years before he was made a lead author. It sounds to me like he was a rising scientist who was willing to take on a job. Experts agreed he was qualified, what data do you have to contradict their assessment? I note this person wrote the 1994 report. If you have to look that far into the past to find a complaint the reports since then must be perfect. Your suggestion that governments should not have any involvement in the SPM is also absurd. The whole purpose of the IPCC is to develop a consensus report for governments to use. The SPM is a political document based on the underlying scientific report. It is the responsibility of the governments of the world to ensure an accurate summary is made. As I recall, the US representative was booed because of some statements he made. The USA generally tried to make the SPM less sure than WG1 and other , more progressive countries, fought to keep the SPM more true to the scientific report. Complaining that a political document was compiled by governments is just arguing for arguments sake. The scientific report has been drafted and reviewed several times before the SPM is written. Final edits are small. Changes are agreed on by expert reviewers. You are arguing that if the report is not perfect, by your ever changing standards, it is not dependable. You will never be pleased since you can just change your standards again. In many countries reports are written and published in different ways than we do in the USA, Europe and Australia. In these areas the gray literature is where the data is. When the IPCC experts used these reports they review them before citing them. You are insisting that the IPCC produce a perfect report, 3000 pages long, in a world that is not perfect. Why do you accept denier garbage that has errors in every paragraph when the IPCC must be perfect?
  9. BEST Results Consistent with Human-Caused Global Warming
    #23 ranyl pretty much speaks my mind. Human discontent, such as demonstrated by the Arab Spring, has already been connected to AGW. I once made a bumper sicker that read "Peace by 1927" because it sounded cool (I'd just read 1984, and like it's author, I reversed the current date.), and a history buff told me that it was about the right date to prevent WWII. So now, as a single issue voter, I might say "Peace with 350 ppm". At least this is something we can theoretically get back to. As it says in Deuteronomy "so that you and your children may live."

    Unprecedented Greenland Ice Sheet Surface Melt
    Not yet. This is the height of the field research season, though. I counsel patience.
  11. Is Greenland close to a climate tipping point?
    @ 4 Chris G You're exactly right. In fact, massive ice loss due to darkening as the mixture between ice and dust (lag) becomes more dusty as ice melts has already been observed elsewhere in the solar system. This process is part of what is thought to have caused Saturn's icy moon Iapetus to have one side which is 10x darker than the other. ref: Spencer and Denk 2010

    Unprecedented Greenland Ice Sheet Surface Melt
    Daniel, Regarding the '150-year natural melt cycle' - any clarification on this from Dr. Box yet?
  13. Debunking Climate Myths from Politicians
    On ABC radio PM program 4 Jun 2012:- MATT WORDSWORTH: The Great Barrier Reef Marine Park Authority issued a report in 2009 citing anthropogenic climate change as a priority issue for the reef. But Queensland's Environment Minister Andrew Powell is not convinced about the role of humans. ANDREW POWELL: Look, I believe the climate is changing; I am still to be convinced of the degree to which we are influencing that. But having said that, are we polluting the environment? Certainly. Are we using a non renewable source of energy? Certainly. Do we need to address both of those factors? Most definitely. As environment minister he should be aware that scientists have positively identified (via carbon isotopes) the source of this additional CO2; it originating from the burning of fossil fuels.
  14. Debunking Climate Myths from Politicians
    The NSW Deputy premier ANDREW STONER: On ABC radio PM program 4 Jun 2012:- MATT WORDSWORTH: New South Wales' Deputy Premier Andrew Stoner recently voiced his concerns about climate science. Three weeks ago he attacked the Climate Commission's report, The Critical Decade, which predicted a rise in heatwave events and flash flooding. ANDREW STONER: This is alarmist, we've heard predictions of all our dams drying up in the past, we've heard predictions of the Central Coast and other coastal parts of the state going underwater, the polar ice caps melting. I'm sorry, none of this has happened so unless he's got some new evidence, I think the average person would be a little sceptical. An example of dismissing the issue by assuming an unrealistic timescale on the predicted possible occurrence of these dire events. He should be reminded of the planetary timescale on which climate change occurs.
  15. Is Greenland close to a climate tipping point?
    Thanks 17, 18 and 19 for your reply. I consider it wishful thinking that "melting could stop"; especially in view of climate warming events over recent years. The adventurous statement by Kurt H. Kjær "the current thinning of the ice sheet is likely to ease within an 8-year period." will unfortunately be fodder for vested deniers.
  16. IPCC is alarmist
    krisbaum - I counted 5284 citations of peer-reviewed scientific literature in Working Group 1 of the 2007 IPCC report (the physical science basis). The 10 citations of grey literature therefore equals 0.19 % of the citations in that report. This is in stark contrast to your claim @ 40: "Something like 1/3 of the references in the last report are grey literature - WWF reports, Greenpeace, news, un-peer reviewed.. etc.." Your claim is total bunk.
  17. Watts' New Paper - Analysis and Critique
    One of the things that's been amusing me about this 'paper' is that it's being referred to as Watts 12. There's a huge assumption here that it will actually find publication this year. Given the extremely poor quality of the first draft, and the length of time it would require to salvage anything from it, let alone to re-write, submit, review, refine, accept, and print any future version, the '12' appellation is optimistic indeed.
  18. IPCC is alarmist
    Krisbaum. You appear to have a very serious problem with 'grey literature'. Given (conservatively) that more than 99.9% of the denialist literature is at best 'grey', what from that body of commentary do you accept, and why? On the matter of the IPCC's use of grey literature, with which of their references do you have particular issue? The most obvious one that I can think of is the 2035 Himalayan glacier melt gaff, which appears to have originated with a tyographic error in reproducing the date 2350. Tellingly, the offending paragraph did not alter conclusions elsewhere in AR4, and if this is as serious as errors go in a document of many hundreds of pages, then even the most stringent scientific publisher would be proud.
  19. IPCC is alarmist
    Source for grey literature claim here.
  20. IPCC is alarmist
    'Interesting. I wasn't aware of those ten grey literature citations in WG1. However I've tallied up the citations in the first 3 chapters of WG1 and there's 1745 citations in those chapters alone. So the grey literature citations make up less than 1% of the first 3 chapters of WG 1. This shows that krisbaum's claim is total bunk, but I may as well tally up the rest of the citations and show the relative percentage. ' wher are you getting your numbers from? My posts got deleted because I didnt provide relevant evidence.
  21. IPCC is alarmist
    Tom; thats news to me! I havent seen that section before. Thanks! Here's what Pachauri has been saying--> “People can have confidence in the IPCC’s conclusions…Given that it is all on the basis of peer-reviewed literature.” – Rajendra Pachauri, IPCC chairman, June 2008 “The IPCC doesn’t do any research itself. We only develop our assessments on the basis of peer-reviewed literature.” – Rajendra Pachauri, IPCC chairman, June 2007 “This is based on peer-reviewed literature. That’s the manner in which the IPCC functions. We don’t pick up a newspaper article and, based on that, come up with our findings.” – Rajendra Pachauri, IPCC chairman, June 2008 i dont think i will write anything more to respond, all the links/evidence I give just gets deleted. Good luck with your climate studies.
  22. IPCC is alarmist
    To add to Tom's comment, the following passages are from the June AR5 WG1 Progress Report: "The IPCC provides governments with a clear scientific view of the current state of knowledge about climate change, its potential impacts, and options for adaptation and mitigation, through regular assessments of the most recent scientific, technical and socio-economic information published worldwide. These assessments are policy-relevant, but not policy-prescriptive." (emphasis mine) and "Working Group I, which covers the physical science of climate change, received 21,400 comments from 659 experts worldwide in the expert review of its first order draft, which ran from 16 December 2011 to 10 February 2012. Working Group I authors are now considering these comments, as they work on the second order draft, which will be available for expert and government review from 5 October to 30 November 2012."
  23. IPCC is alarmist
    Krisbaum, the with regard to the IPCC AR4 Working Group 2 report, the IPCC states:
    "The Working Group II Fourth Assessment, in common with all IPCC reports, has been produced through an open and peer-reviewed process. It builds upon past assessments and IPCC Special Reports, and incorporates the results of the past 5 years of climate change impacts, adaptation and vulnerability research. Each chapter presents a balanced assessment of the literature which has appeared since the Third Assessment Report[1] (TAR), including non-English language and, where appropriate, ‘grey’ literature."
    (My emphasis) Your thesis that the IPCC claims to not use grey literature is, therefore, clearly false. The IPCC has clearly delineated procedures for the use of grey literature. Clearly you are arguing a straw man. If you would actually like to address the issue of the quality of references used by showing scientific flaws in the references that have made it into the reports, you might have something interesting to discuss. As it stands your are simply trying to denigrate the reports by innuendo.
  24. IPCC is alarmist
    Interesting. I wasn't aware of those ten grey literature citations in WG1. However I've tallied up the citations in the first 3 chapters of WG1 and there's 1745 citations in those chapters alone. So the grey literature citations make up less than 1% of the first 3 chapters of WG 1. This shows that krisbaum's claim is total bunk, but I may as well tally up the rest of the citations and show the relative percentage.
  25. IPCC is alarmist
    As someone who has been yelled at several times (and gotten over it) for doing the same thing you've just done, I must point out that it is possible to write better, more to-the-point posts. Give your thesis and supply the evidence. Don't dance around with insinuations and "look there! uh-huh . . . wink wink."
  26. IPCC is alarmist
    Leave it, DB! No statement could better cap off the pointless exercise that krisbaum has just performed. I think krisbaum thinks s/he is special for having had posts deleted. If so, we're all special.
  27. IPCC is alarmist
    Right, krisbaum, and I am asking you if you think the PhD theses lack quality because they haven't been peer-review by journal reviewers for a journal. Have they been reviewed by experts? If you've been through a PhD defense, then you know the answer. It's entirely possible that the review was performed by scientists who do review work for journals. And I am quite certain that the IPCC reviewers didn't simply accept the theses as the equal of peer-reviewed, published work. The IPCC has used grey literature. They point this out themselves. What is your point? Do you have a hypothesis to share with the group?
  28. IPCC is alarmist
    [DB] Um, no. - please be a bit more specific? Um no to what exactly?
    Moderator Response: [DB] Read the linked post, which documents that in detail.
  29. IPCC is alarmist
    DSL- my original point was that the IPCC does not produce a report solely on peer reviewed literature. It advertises the fact that it does - agreed? Its not whether the science is good or bad in the grey literature, you cannot tell the world your report is only based on peer reviewed literature - when in fact it isnt.
    Moderator Response:

    [DB] Your citations are insufficient because you fail to demonstrate for each which specific portions of WG1 they are based on and why the reference you cite fully fulfills the role of citation for that section.

    Simply copy-pasting from fake-skeptic sources is insufficient. It is incumbent upon you to demonstrate the relevance of each source you cite to support your extraordinary claim.

  30. IPCC is alarmist
    krisbaum, you assign blanket mistrust to the category "grey literature." I guess you assume that because the PhD thesis was not published, it must not be trustworthy. Something must be "wrong" with it. You should let the thesis committees for these individuals know that you've caught on to their fraud. What is your assessment of these pieces of "grey" literature? Are they good science? PhD theses/dissertations are not published for a variety of reasons.
  31. IPCC is alarmist
    the above are referred to as grey literature because they are; '"information produced on all levels of government, academics, business and industry in electronic and print formats not controlled by commercial publishing" ie. where publishing is not the primary activity of the producing body." (ICGL Luxembourg definition, 1997 - Expanded in New York, 2004)'
  32. IPCC is alarmist
    a reference from WG1 that is from a grey source; Jiang, Y.D., 2005: The Northward Shift of Climatic Belts in China during the Last 50 Years, and the Possible Future Changes. PhD Thesis, Institute of Atmospheric Physics, China Academy of Science, Beijing, 137 pp.
    Moderator Response: [DB] Um, no. This citation is covered by this SkS post here.
  33. IPCC is alarmist
    a reference from WG1 that is from a grey source; Vérant, S., 2004: Etude des Dépressions sur l’Europe de l’Ouest : Climat Actuel et Changement Climatique. PhD thesis, Université Paris VI, Paris, France, 204 pp.
    Moderator Response: [DB] Which portion of WG1 specifically? And why do you think this is a "grey" source (your comments still do not specifically comply, but this becomes tedious)? More is required than merely furnishing a source lacking a link.

    As an FYI, you are not complying with this site's Comments Policy; specifically, this section:
    "No link or picture only. Any link or picture should be accompanied by text summarizing both the content of the link or picture, and showing how it is relevant to the topic of discussion. Failure to do both of these things will result in the comment being considered off topic."
    Which has resulted in your two three most several recent comments being deleted. You have elected to assign yourself the task of showing which section of WG1 is based on grey literature. Please proceed to do so.
  35. IPCC is alarmist
    'Don't expect SkS readers to fossick around in that mess. Cite one portion from WG1 that is based on 'grey literature.' ' I already cited on Rob http://www.newscientist.com/article/dn21940-climate-panel-adopts-controversial-grey-evidence.html
    Moderator Response:

    [DB] Do you understand the distinctions between WG1, WG2 and WG3? Your link (essentially a newspaper article/blog post) deals with WG2, not WG1.

    Again, you asserted that the whole IPCC report, which includes WG1, was based on grey literature.

    Try again.

  36. IPCC is alarmist
    'Rob, I think it would fairer to suggest the krisbaum is reading frothing-at-mouth denialist sites and prefers to believe what he is told there.' I think its a little unfair you can write such things about me - I havent been nasty to anybody here.
    Moderator Response:

    [DB] "I havent been nasty to anybody here"

    Actually, your very first comment in this forum contained sufficient vitriol towards a regular member of this forum that the entire comment necessitated immediate deletion. Nevertheless, can all participants exercise more discretion in their comment formulations, please?

  37. IPCC is alarmist
    Rob, I think it would fairer to suggest the krisbaum is reading frothing-at-mouth denialist sites and prefers to believe what he is told there. krisbaum, you are implying lead authors have "vested interests" in results. What is the basis of this belief? By the way, I would be perfectly happy for Exxon staff to be reviewing and writing what they would so long as they are Exxon's scientists. I am oil man. By your interpretation of the world, I should be a rabid anti-AGW activist because AGW threatens my current position. In fact, I mostly find widespread acceptance of the IPCC conclusions among my colleagues and client's scientists.
  38. IPCC is alarmist
    Don't expect SkS readers to fossick around in that mess. Cite one portion from WG1 that is based on 'grey literature.' If you're familiar with the details it won't take long. We're waiting.............
  39. IPCC is alarmist
    How about showing us a portion in WG1 (the scientific basis) that is based on 'grey literature.' Failure to do so will lead to the inescapable conclusion you simply made that up.
  40. IPCC is alarmist
    DB - i cant furnish your request unless I know what your interpretation of 'reputable' is ????
    Moderator Response: [DB] Either something like a commentary paper in a peer-reviewed journal or showing directly which section of WG1 was based on which specific piece of grey literature. It was your statement; it is incumbent upon you to be able to furnish documentation supporting it...or to withdraw the assertion.
  41. Watts' New Paper - Analysis and Critique
    Just saw this little gem over at WUWT: Ric Werme says: August 3, 2012 at 1:58 pm ........... It might be interesting to take pre and post homogenized data and see how that displays and analyzes. Is there anyone here who can help this poor guy out? ;)
  42. IPCC is alarmist
    'To suggest that government should not be involved is absurd. ' Thats correct, the government should not be involved in generating the report. Like I mentioned before, do you have the police judging their own court cases? Do you have the government enforcing their own laws? We have separate entities for a reason. 'what like the scientists of the world? That was the idea in drawing up the IPCC. Who do you propose should do this audit? the uninformed?' Its pretty easy to find people that have no vested interests in the IPCC's conclusions. You dont need to audit what the auditors write - you just need a cross-check from another external party. Over a 3rd of their sources are grey like i mentioned, yet Pachauri declares all sources 'peer reviewed literature'. So he says one thing and does another. Let it be clear the shortfallings of the report, or enforce your standards. Grey literature is used throughout the whole IPCC report. The fact you admit there was grey literature is enlightening. Dont you therefore see it a problem Pachauri tells everybody that its peer reviewed when its not?
    Moderator Response:

    [DB] "Grey literature is used throughout the whole IPCC report."

    Please provide a link to a reputable source that documents the usage of such literature in WG1, or, failing that, provide a link to that portion of WG1 in question and to the grey literature on which it was based. Note that fake-skeptic blogs are not reputable.

    Failure to provide such a link will result in further moderation of your comments here.

  43. IPCC is alarmist
    krisbaum at 10:23 AM on 4 August, 2012 Actually, you have made my day. Thanks. I think these news broke here at SkS too but I somehow missed it. And ok, you realize the police/judge/offender juxtaposition was a bit too much. Thank you again for being this open minded. So your main criticism is that the process does not garantee the quality of the information. You even imply that it has vested interests, and is therefore biased (correct me if I read too much from your comment). I will set aside for a moment the fact that it is painfully and repeatedly reviewed by thousands of scientists from all over the world before publication - including countries that make great efforts afterwards to ignore it in pratice. After 22 years, we have had time to check some of the main projections, and they are basically right. Even too conservative sometimes (sea level rise). Where would you say the report missed the point and got carried away by its "bias"? (it's bedtime here in Brazil, so see you tomorrow)
  44. IPCC is alarmist
    "You have countless IPCC staff who are inexperienced scientists and not experts. They determine what to include and what to not include from the science - and that doesnt just mean peer reviewed". The IPCC doesnt have countless staff - it has next to none. The review decision is by lead authors who are not IPCC staff and are chosen as the experts in their field.
  45. IPCC is alarmist
    Krisbaum - governments govern. That's what they do. They do it will if their policy is well-informed. To suggest that government should not be involved is absurd. They requested the report. Yes, the editors make their decisions but every decision is transparent. Which one do you agree with. You want audit by others with no vested interests - what like the scientists of the world? That was the idea in drawing up the IPCC. Who do you propose should do this audit? the uninformed? And whose choses the auditors? And would you then demand audit of the auditors if you still didnt like the answer. Note that "grey literature" was only used by WG2 in the absence of any other. However, you are challenging WG1 but so far I dont see a basis for that.
  46. IPCC is alarmist
    *if it wasnt for these people we'd have polluted water, rivers and probably be dead by now.
  47. IPCC is alarmist
    DSL; There is no error in my analysis - the problem is much wider than 'a few erros and loose practices'. You have countless IPCC staff who are inexperienced scientists and not experts. They determine what to include and what to not include from the science - and that doesnt just mean peer reviewed, they also include other grey literature. Something like 1/3 of the references in the last report are grey literature - WWF reports, Greenpeace, news, un-peer reviewed.. etc.. If you believe this kind of working practice is acceptable then fair enough, I on the other hand think its not. The world needs people who believe and are passionate. I have no problem with activists, climate activists or environmentalists - on the contrary - if it wasnt for some of these people, but - you have to consider people's vested interests and take precautions to make sure those interests dont get in the way. It would be like the IPCC obtained funding and had 1/3 of its staff filled with Exxon employees. What would you think then?
    Moderator Response:

    [DB] "You have countless IPCC staff who are inexperienced scientists and not experts."

    Participants here are not allowed to simply make things up as they please. You will need to furnish source citations for extravagant claims such as this. Else moderators will intervene.

  48. IPCC is alarmist
    krisbaum: "My suggestion is that, considering the report produced by the IPCC is being used to decide one of the most critical fates of humanity - spending trillions on alternative energy in effect - there could be an external policing of their processes." This represents a fundamental error in analysis on your part, krisbaum. The IPCC ARs gather the existing science and integrate it into a readable summary. If the IPCC did not exist, the science would still be there saying the same thing, and the probable outcomes would be just the same (or arguably worse). You imply the IPCC is a bad idea and subject to corruption. I say not having the IPCC is a worse idea. I can imagine a version of the IPCC that is worse than nothing at all, but the current form is far, far from that. I agree that the process can improve, but I fail to see how a few errors and loose practices (recognized and in correction) are justification for condemning the whole process. You also seem to assume that all of the regular SkS posters bow before the IPCC and are oblivious to its problems. No. In fact, they are so aware, from having to explain it daily, that they know where practice is sound and where it needs work. It is a large project with many aspects. It does inform the world, and it does a much better job than individuals trying to piece together the science and then explain it and the implications to the world.
  49. IPCC is alarmist
    Michael Sweet; ' In fact, the governments of oil producing countries, with help from the USA, diluted the conclusions of the scientists in the SPM. Your suggestion that the IPCC is alarmist is backwards, it reduces the conclusions to make AGW seem less of a problem' Well, this alarms me just as much as the opposite. No government should have their hands in diluting or concentrating such a report. Its my point exactly. At least we agree that politics is getting in the way ;).
  50. IPCC is alarmist
    Alexandre, It is here in Australia - the IPCC is quoted as the definitive place to go to for climate change science/recommendations. It was pivotal in the stern report brought out in the UK, and without it there wouldnt be a Carbon Tax in Australia. I think the police analogy came across wrong. What I mean is, they produce a report but there is no external auditor or group of people that have no vested interests, scrutinising the report and how its generated. So Alexandre - ther's your meaningful example - the Carbon Tax in Australia.
