  1. The Y-Axis of Evil
    No offense intended,,, I think jimspy sort of has a point in that larger numbers have an effect on peoples' perception. (humor) I would indeed be probably more understandable to general public if, let's say 0,05 picoCelsiuses would be converted to... let's say 'negative dollars'. Then it could be easily stated that we're fighting against a temperature rise of -40'000'000'000'000 dollars. This might even be divided against the negative of population of the earth to get the temperature rise per person to get 5714,3 dollars/person which would approximate towards the cost of conversion of a averge american household running on renewables instead of fossils. It might be I got the numbers wrong there. Of course this sort of scale would only obfuscate the argument for those using €s or other currencies, like the Zimbabwean dollar which (at least a couple of years ago) was the basic unit of currency being the smallest measurable unit of currency (the so called 'Planck currency') (/humor) Of course this sort of thing has been calculated better in those carbon trading schemes, but apparently nowadays people are talking more about carbon taxes.

    From Peru@2 Hasn’t Watts got two eyes in his head?
  3. 2012 SkS Weekly Digest #52
    I have made a comment on the previous open thread, about one article at WUWT: The Geodetic Reference Antenna in Space (GRASP) It claims that the current Terrestrial Reference Frame is riddled with sistematic errors, making satellite Sea surface altimetry (TOPEX-POSEIDON-JASON1-JASON2) and gravimetric (GRACE) measurements to be unreliable data. If this issue is not clarified, it could become a major argument against global warming, perhaps one of the strongest ones.
  4. Perspectives of 8 Scientists Attending AGU Fall Meeting
    Boswarm @ 2, you said "The sleeping masses won't wake up!" Regrettably, they have not yet woken up and their peaceful slumber is being perpetuated by mass media non-science such as the article you linked to in The Age. Nothing would make me happier than scientific evidence that all the effects of AGW, which are currently being measured, are wrong. I can promise that such science will not be found in popular newspapers, such as The Age, but in reputable scientific journals, where the science is put to the test of peer review. So far, the papers denying AGW are very thin on the ground.
  5. 2012 SkS Weekly Digest #52
    Well, that’s very interesting - best/most popular “science websites”. I looked them up and WUWT, Jo Nova etc. are nowhere to be seen. Now best “science blog sites” is a different matter. There are WUWT and the rest of the pseudoscience crowd. Must be the dodgy voting system that the blogosphere folks use to come to such a startling conclusion. Skeptical Science has won an award for demolishing denier’s myths, and if they changed the blogosphere voting system would undoubtedly beat the denier blog sites hands down. Go Skeptical Science, and fully informed New Year to all us readers.
  6. Contrary to Contrarian Claims, IPCC Temperature Projections Have Been Exceptionally Accurate
    All I can do is LOL at cormagh @24. No matter what dataset you pick, deniers accuse you of cherrypicking. You average multiple datasets together, and you're accused of 'combining temperature records to prove your point'. There's just no winning with denialists.
  7. The Y-Axis of Evil
    Vroomie & Villabolo: From my decidedly un-scientifically-uneducatedly layman's POV, working as I do with the Great Unwashed, I have to point out, as does Villabolo, that the masses are only dimly aware that there two temperature scales (and don't even mention Kelvin to them). At the very least, they are not -instinctively- aware of the six-degree problem, and must be told about it. And then it's a crapshoot as to whether they believe it, or become fully invested in it. The average person thinks, When I drive from New York to Miami in the winter, the temperature goes up THIRTY degrees, so how bad could 6 be? It's probably a bit difficult for some scientists to fully appreciate the depths of American ignorance of science, working as they do with colleagues and interested students who have acquired a modicum of knowledge. But people do react to large numbers, and I merely thought the opportunity for us to say the words "Six thousand millitherms" would give us a chance to open some eyes. However, if you think it will muddy the waters, or give deniers yet more fodder for lobbing grenades, forget I mentioned it.
  8. Contrary to Contrarian Claims, IPCC Temperature Projections Have Been Exceptionally Accurate
    cormagh - It's not terribly common to average multiple temperature records in these discussions. But this certainly short-circuits the "You used a data set that (has poorly specified problems that boil down to contradicting my point of view)" arguments commonly heard from 'skeptics'. Personally, I prefer GISTEMP for accuracy, as it avoids the polar holes present in (for example) the HadCRUT and satellite data. And that's because I prefer looking at all the data rather than subsets. But again, averaging multiple data sets is reasonable, and probably preferable to plotting multiple data sets in this already crowded graph.
  9. Contrary to Contrarian Claims, IPCC Temperature Projections Have Been Exceptionally Accurate
    Regarding Figure 1, when did it become common to combine whatever combination of temperature records were needed to prove one's point?

    An afterthought, have any of the gardeners here thought of permaculture? Can orchards be more resistant to the weather than other crops?
  11. Food Security: the first big hit from Climate Change will be to our pockets
    I believe that any future civilization will have to rely on solidly built greenhouses to shelter crops from the local weather.
  12. The Y-Axis of Evil
    @ vrooomie & jimspy Jimpsy, I know you're thinking from a PR point of view but there is a flaw in your terminology. "Milli" is a well known term by the public for thousandths thus using it will give the impression of triviality. A more public friendly response to this pseudoscientific nonsense would be to simply state that the chart has been "compressed" or "squashed down" or some similar phrase that the public can understand. vrooomie Most Americans, uneducated as they are, won't fully appreciate what a 6C rise would do; especially if they live in a relatively cool place.
  13. Perspectives of 8 Scientists Attending AGU Fall Meeting

    Ive found this a REALLY USEFUL APP but since Ive started using Windows8 it doesn't accept my log-in. Ive tried logging in on Sks but the app (sorry add-on) asks me to log in again, i do so but nothing happens. Anyone else having this problem?
  15. The Y-Axis of Evil
    Respectfully, jimspy, and from my POV as a earth scientist, I see absolutely no reason whatever to muddy up the discussion with a new metric of temperature. Degrees are widely-and well-understood by lay and scientific folk, and though we (Americans) still cling to our Fahrenheit, over the *rest* of the world, there is still a plenty enough comprehension of what a 6C temp rise will be: Uninhabitable.
  16. This is Global Warming - A Lesson for Monckton and Co.
    Ron King, you're really asking the wrong question. Relevant questions are: "What qualifications do Drs. Douglass and Knox have as "climate scientists" Douglass and Knox paper on ocean heat content is the one that Nuticelli et al. (2012) address] answer: none. Douglass is a low temperature superconductivity physicist. He gained his PhD in 1959 and essentially retired as a publishing physicist in 1991 (his last paper in the area of his expertise was published in 1991). Knox is a spectroscopist with a particular focus on biological photochemistry. He gained his PhD in 1958. "Why are Drs Douglass and Knox writing occasional papers in an area completely divorced from their expertise in their late 70's? answer: Difficult to understand. Their first paper in their late career choice [Douglass, Blackman and Knox (2004) Temperature response of Earth to the annual solar irradiance cycle. Physics Lett. A. 323, 315-322] was scuppered by their error in not accounting for the fact that the (albedo-corrected) total solar irradiance has to be divided by 4 to account for the spherical geometry of the Earth when considering the Earth-absorbed irradiance. The smattering of papers this pair have published since on climate science have almost uniformly been shown to be blatantly flawed by rebuttals published in the scientific literature. The answer to your question: "...is John Church the only recognised climate scientist among the co-authors..." answer: John Church is a recognised climate scientist. That's ONE MORE than the authors of the paper Nuticelli et al. are addressing. Robert Way is a graduate student studying glaciology, climate statistics and climate change attibution. John Cook is at the Global Change Institute at the University of Queensland. That seems like quite a bit of climate expertise status to me (If it's "staus" you're after which seems to be the case). Judging by the postings at this site the other authors have the requisite qualities to address the issues, i.e. a strong physical understanding and honesty. Three questions for you Ron: 1. Couldn't you have found this out for yourself? 2. Don't you think it's a little odd that two elderly physicists choose to write very occasional papers on subjects completely outside their expertise, and that are objectively shown to be wrong? 3. Don't you think it's quite a good idea that objectively flawed analyses that find their way into the scientific literature are robustly rebutted?
    Moderator Response: (Rob P) Ron King was yet another sock puppet of Ken Lambert - banned some time ago for troll-ish behaviour.

  18. 2012 SkS Bi-Weekly News Roundup #12
    I was navigating the internet when I found this posts in WUWT: Why ice loss and sea level measurements via satellite and the new Shepherd et al paper are highly uncertain at the moment Where, after briefly reviewing the Shepherd et al. paper A Reconciled Estimate of Ice-Sheet Mass Balance that makes a review on ice sheet melting related sea level rise, show this: The Geodetic Reference Antenna in Space (GRASP) -A Mission to Enhance the Terrestrial Reference Frame Where is stated that there are systematic errors in the Terrestrial (GPS?) Reference Frame that would make highly uncertain the measurements of the TOPEX-POSEIDON-JASON1-JASON2 satellite altimeters and GRACE ice sheet and ocean mass gravimetric data. They show, for example, this slide: As an example that “TRF errors readily manifest as spurious sea level rise accelerations” So that WUWT concludes “A good first step would be to get the GRASP mission funded and then go back and redo Shepherd et al to see if it holds up. Until then, it’s just noisy uncertain data. ” I do not know what to think about it. If true, this is a serious blow to the satellite missions and all their data. Note: sorry for the big size of the slide. In the comments policy page the HTML tag to re-size images does not work.
    Moderator Response: [RH] Fixed image width that was breaking page formatting.
  19. The Y-Axis of Evil
    Bernard J: I realize that, which is why I went for the more specific "millitherm = 1/1000th of a degree CELSIUS." Creating a new term gets the media's (and their readers') attention. And attention is what is needed, and quickly. It also allows us to speak in terms of hundreds, and not "hundredths."
  20. Food Security: the first big hit from Climate Change will be to our pockets
    Have added an image of a waterlogged arable field to the end of the post. Right across the English Midlands similar scenes are everywhere. Had a few beers with a local farmer last night and the conversation revolved around ground conditions and how on earth these fields could be ready for spring planting.
  21. Mexican Climate Legislation and Other Hopeful News
    At pwc page Low Carbon Economy Index 2012: Overview we have the following statement: "Even doubling our current rate of decarbonisation, would still lead to emissions consistent with 6 degrees of warming by the end of the century. To give ourselves a more than 50% chance of avoiding 2 degrees will require a six-fold improvement in our rate of decarbonisation." The full report in pdf format can be downloaded from a link at the bottom of the page linked above.

  24. Mexican Climate Legislation and Other Hopeful News
    The Price Waterhouse Coopers reference/link is weak. It points to a Guardian blog piece which itself refers to other Guardian pages, which in turn are a bit dead. I would like a reference to the actual PWC information.
  25. Perspectives of 8 Scientists Attending AGU Fall Meeting
    "What is more, they do so only by a massive and deliberate cherry pick of an interval with an extreme El Nino at the start and multiple strong La Nina's at the end - a circumstance that should lead to a strong cooling trend. Instead we have a weak warming trend indicating a strong underlying trend." Can anyone point me at any actual research out there examining this proposition in detail? The proposition makes sense to me, and should, i think, be an "oh dear, WTF is actually going on here" moment in the "debate" about anthropogenic climate change. Yet the "no warming for 16 years" is the current "killer" meme amongst the skeptic lobby when the data its based on, maybe, has serious implications for a warming future.
  26. This is Global Warming - A Lesson for Monckton and Co.
    Ron @60, "...should not be attacked for not being a climate scientist by people who aren't climate scientists." Your red herring argument dismisses one and all critiques made by non-climate scientists in this faux debate? You are conceding that the opinions Monckton, Watts, McIntyre, Ridley, McKitrick, Morano, Michaels, Pielke Jnr., Inhofe, Bastardi, Douglass, Knox, Singer, Easterbrook, Peiser, McLean, Jo Nova, Montford, Mosher, Baliunas, Loehle, Tom Harris, Muller, Liljegren, Condon, Happer, Lewis, Plimer, Soon, Idso, Tisdale, Dyson and many, many other fake skeptics and contrarians are to be ignored when it comes to climate science. For the record, in science it is not considered an "attack" to note legitimate and noteworthy errors and flaws in arguments made by fake skeptics and those in denial. Trying to invoke that hyperbole in a scientific debate is conceding that you have lost and are grasping at straws.
  27. This is Global Warming - A Lesson for Monckton and Co.
    Ron King - Global energy is increasing, despite all variations (ENSO, low solar cycle) and some forcings (aerosols) currently acting to decrease that warming. All that, and the trend is still up, which shows the strong long term warming trend. If there wasn't a trend under the noise, we would be seeing a strong temperature drop right now - which we are not. You can continue to claim that short term variations in warming indicate (to you) that the world is now cooling - and those with any knowledge of statistics will continue to see that you are just looking at the noise. Year to year variations are on the order of 0.2-0.4°C (peak-to peak ENSO is ~0.4°C, for example). The trend shows 0.8°C over the last hundred years or so, 0.16°C per decade over the last 40 years - and to see that you need to look at enough data for the signal to be larger than the noise. Stats 101 - make certain you're looking at signal, not at noise. The rest of your post consists of, quite frankly, Arguments from Authority. That does not support your argument.
  28. This is Global Warming - A Lesson for Monckton and Co.
    dana 1981 (-argumentative wordplay snipped-). Regarding your cited paper 'Nuccelli et al 2012' - is John Church the only recognised climate scientist among the co-authors? (-reverse argument from authority snipped-).
    Moderator Response:

    [DB] "...is John Church the only recognised climate scientist among the co-authors..."

    Non sequitur. As noted, arguments from authority used as denigration do not advance the dialogue. If you have nothing positive to add to this conversation, then refrain from detracting from it. Please thoroughly review this site's Comments Policy before composing any future comments.

  29. The Y-Axis of Evil
    I've seen similar trolls on Slashdot: . Note that the average depth of the ocean is 3790 meters. Graph that including zero, and I think it is safe to say that a 0.1% increase would look like no change at all -- a mere 3.79 meters.
  30. Perspectives of 8 Scientists Attending AGU Fall Meeting
    Michael @ 4: Somehow the myth of Sandy as just another storm has persisted…check Jeff Masters’ blog for a more fact based look: This is a storm that essentially simultaneously blew over things in Indiana and Nova Scotia, 1500 miles apart. http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=2293 Science Michael, bring us some science….as scaddenp suggests….
  31. Perspectives of 8 Scientists Attending AGU Fall Meeting
    Perhaps Michael would like to point us instead to published science that supports his point of view. That would be a worthwhile topic of conversation. Even perhaps pointers to where this site is making claims that are not supported by published science might be educational.
  32. Perspectives of 8 Scientists Attending AGU Fall Meeting
    Rob @10, typically, as you know, the constant barrage of insults, accusations of fraud, and/or conspiracy against climate scientists and their defenders in both blogs and commentary on denier sites is invisible to their perpetrators. Despite the barrage of invective they hurl, they are always ready to take insult on the slightest pretext.
    Moderator Response: (Rob P) Please focus on the science. Michael's attempts to draw readers attention away from the facts (blimp-pointing) should be ignored.
  33. Perspectives of 8 Scientists Attending AGU Fall Meeting
    Look, rather than me speaking for Boswarm, let us ask him if he will clarify what exactly he meant by his statement.
  34. Perspectives of 8 Scientists Attending AGU Fall Meeting
    Michael of Brisbane @4, 1) Weather is actually becoming extreme, as illustrated by the 2010 Moscow heatwave (a on in a thousand year event, according to the Russian weather service); or the recent heatwaves and droughts in the United States. Deniers like to play the silly game that just because there is a one in a thousand chance of an event occurring without global warming, therefore global warming did not contribute to the event. That reasoning is, of course, simply denial. 2) Hurricane Sandy was unprecedented in its diameter, and exceptional in terms of its Accumulated Cyclone Energy for a Hurricane making landfall so far north. Just because it is not unprecedented by all measures does not make it "not unusual in any way". 3) The Age article was a disgrace, trotting out denier talking points with no evidence of independent thought of analysis. The simplest case of this is the claim that the last 16 years represents a "pause" in global temperature rise, base on the fact that the continuing positive trend over that period is statistically indistinguishable from zero. That claim is, first, nonsensical. The trend over teh same period is also statistically indistinguishable from rates of warming higher than those predicted by the IPCC. If the inference from being statistical indistinguishable from zero is valid; then so also is the parallel and opposite inference. Denier's who push this claim, therefore, avoid contradiction only by selective and inconsistent reasoning. What is more, they do so only by a massive and deliberate cherry pick of an interval with an extreme El Nino at the start and multiple strong La Nina's at the end - a circumstance that should lead to a strong cooling trend. Instead we have a weak warming trend indicating a strong underlying trend. The extent of the cherry pick is made clear by comparing the trend over the last 32 years to that of the first 16 years of that period. The 32 year trend (0.158 C per decade) is appreciably greater than that of the first (0.093 C per decade) and last (0.87 C per decade) 16 years of that interval. The closeness of the 16 year trends shows that, by denier reasoning, warming occurred in neither the first 16 years, nor the second. Therefore, deniers are logically committed to the claim that there has been no warming over the last 32 years, despite the strong warming trend. The simple fact is that if you allow yourself to play silly buggers by deliberately misinterpreting statistical facts, and cherry picking your data, you can pretend to prove anything you desire. This is something deniers take full advantage of. 4) I am unimpressed that you take offense to a term first used in writing the English language 400 years before the Holocaust. Because of its ancient history, the pretense and manufactured outrage about the supposed imputation that deniers of climate science are the moral equivalents of holocaust deniers is ludicrous. Frankly, I take offense at the denier's blatant attempt to manipulate the language so that a plainly accurate descriptive term will not be applied to them. Indeed, I take greater offense at the retreat from rationality inherent in the entire climate science denying movement - a retreat from rationality that will have real, and harmful consequences to my children, and theirs.
  35. Perspectives of 8 Scientists Attending AGU Fall Meeting
    Michael @4... Clearly you do not live in the NY region. Nor are you paying attention to what the science is saying about weather extremes.
  36. Perspectives of 8 Scientists Attending AGU Fall Meeting
    @ Michael. Have you actually read/studied the most used used climate myths on this site. They are available for your perusal anytime. Just scroll to the top of the screen and look left, where it says in BOLD RED printing. Most used climate myths. As for Boswarm's term "allowing". Try looking up the meaning of the word "irony". OK ? Now be a good boy and do your homework.
  37. Michael of Brisbane at 06:53 AM on 30 December 2012
    Perspectives of 8 Scientists Attending AGU Fall Meeting
    I think that what will "wake the sleeping masses" is for at least some of the predictions from modelling (and alarm) to actually happen, and for weather to actually become "extreme". Hurricane Sandy was not unusual in any way when compared historically, nor is any weather event that is blamed on AGW nowadays. Thanks Boswarm, for the link to that article in The Age too. (did you really use the word "allowing"??) That article sums up my stance on AGW pretty well. (especially what it says about the use of the word "denier".) I am indeed one of the "sleeping masses" and I am very much awake already, thank you.
  38. Perspectives of 8 Scientists Attending AGU Fall Meeting
    For some reason I couldn't access the video. May just be my slow system. The only thing that will wake up the masses is a few more Sandys squared. There are already signs that the drought in the USA, Sandy, Arctic ice melt and a couple of other relatively mild events (relative to what is likely coming) are already having an effect on public opinion. I find it very hard to believe that even the most extreme measures at this late date to reduce carbon emissions would stop the brown stuff from hitting the wind pusher.
  39. Contrary to Contrarian Claims, IPCC Temperature Projections Have Been Exceptionally Accurate
    Ron, yes the overall decadally (or multi-decadally) averaged ENSO will be small over the coming decades. However ENSO can make a large contribution over a period of several years to a decade (depending on the length of time ENSO persists in an overall positive or negative mode). Can't really say what solar/volcanic influences will be in the coming deades since their variability is (as far as we can say) stochastic outwith the solar cycle. The solar contribution is expected to be small. However a prolonged solar "downturn" can make a persistent (small) contribution to surface temperature. So inspection of the ENSO index indicates it's been largely negative especially during the last 6 or 7 years. Likewise there has been a rather anomalous progression of solar activity with an extended minimulm out of cycle 23. These add up to a significant negative contribution to surface temperature since about 2005/6. So the decadal temperature trend just past is suppressed. That's not difficult to understand I think. However neither of us needs to attempt to characterize these contributions in words since Foster and Rahmstorf (2011) have done the calculations!
  40. IPCC Draft Report Leaked, Shows Global Warming is NOT Due to the Sun
    Tom Curtis #114-That is an excellent point,and I would like to add to your comment: "Rawls, very carefully keeps the two analyses separate to avoid that falsification; but such methods turn his theory into pseudo-science." I would amend that to read "...such methods turn his theory into Pathological Science"
  41. This is Global Warming - A Lesson for Monckton and Co.
    My response is that you're going down the up escalator.
  42. Contrary to Contrarian Claims, IPCC Temperature Projections Have Been Exceptionally Accurate
    Ron, read the paper. You're basically saying "I don't agree with the results of FR11 because my eyeballs disagree". Sorry, eyeballs are subject to bias, statistics are not.
  43. Contrary to Contrarian Claims, IPCC Temperature Projections Have Been Exceptionally Accurate
    dana 1981 Looking at your post on FR201: The authors conclude by averaging all of the data sets together (Figure 4): "Because the effects of volcanic eruptions and of ENSO are very short-term and that of solar variability very small, none of these factors can be expected to exert a significant influence on the continuation of global warming over the coming decades. ." This says that the effects of ENSO, volcanoes and solar are effectively small to negligible over the coming decades. Yet you conclude that those 3 factors were significant (cooling) effects over the last 2 decades - effectively masking the AGW warming signal with natural cooling factors. Again there are nearly 2 solar cycles in the last 20 years which should neutralize TSI effects which are small anyway according to FR, volcanic chart shown Pinitubo (1993?) as the only major volcanic cooling effect (short term), which leaves ENSO which is also short term and not expected to be decadal factor in the future. So practically the whole case rests on ENSO being a major cooling factor in the past 20 years - so much so that it has flattened the temperature trend from 0.18 down to 0.06 deg/decade. Sorry, I can't see this from the MEI chart from FR 2011 from 1990 - 2010. Neutral to slightly positive over 20 years looks more like it.

  45. The Y-Axis of Evil
    Chriskoz: don't say this "I become depressed and I really wish that "polar bears" be replaced with "homo sapiens" in their silly, ignorant talk" Don't give up - it's the only way to defeat the mindset of the Cranks above. The collective will win.
  46. The Y-Axis of Evil
    Bernard @26, Denialists often show your temp graph (of the Cenozoic era from d18O proxy) but dress it in precisely opposite ethical considerations: "the Earth was far warmer few My ago, so a little bit of warming ain't bad... Acrtic ice will melt and polar bears will go extinct as the result? So what? Extinctions have always been happening and old species have been replaced by new ones. Polar bear will be replaced by a better species" When I'm looking at such thoughtless crank, and see other egotic cranks or such being our policymakers (i.e. reps in US, libs in Australia), I become depressed and I really wish that "polar bears" be replaced with "homo sapiens" in their silly, ignorant talk. If homo sapiens' collective mindset is determined by the lowest denominator (i.e. a crank above), then this species is not worth living on this planet.
  47. CO2 effect is saturated
    Now a specific question: In NACAR from Archer web site I keep everything default except I increase the high cloud fraction from zero. The temperature goes down, not up. As an amateur here I have absorbed the "high clouds tend to add to the Greenhouse Effect, low clouds tend to reflect" (over?)generalization. So why does adding high clouds cool in this NACAR program at default settings? I do not think there is a way to ask a question on line with that course.

    The weather effects of an ice free Arctic, let alone those of sea level rise, will propagate across the planet.

Anyone who is not alarmed by now must be living in an alternative universe where the laws of physics do not apply. Fool's Paradise, my Gran would have called it.
