Comments 57901 to 57950:

  1. New research from last week 23/2012
    I could find no indication that Judith Curry participated in the North Carolina workshop on uncertainty.
  2. Pal Review - the True Story and the Fairy Tale
    Dikran wrote: "Seriously, there are very good reasons why the possibility of a natural cause can be effectively ruled out completely." Maybe we should establish a standard of requiring that people provide a citation of at least one climate scientist making a claim before we'll entertain it. Or get a list of the published 'skeptic' scientists and check if any of them will put their name behind it. So far as I know there are not any who dispute that humans are responsible for the increase in atmospheric CO2 levels. Or that this increase is causing planetary warming. Even with the 'pal review' system documented in this article, there are some claims that are just too ridiculous. Lindzen, Michaels, Spencer, Christy, Pielke... they all acknowledge that human CO2 emissions are increasing global temperatures. Yet here we have Rufus professing 'skepticism'. Indeed, one of the few good things with the progress of the global warming 'debate' is the ever shrinking pool of contrary claims which the 'skeptic' scientists are willing to put their names behind. If we could get the online 'skeptics' to observe the complete absence of scientific support for positions like this it could wipe out about 95% of the crazy things they believe (e.g. 'undersea volcanoes are melting the Arctic ocean ice') and just leave, 'ok you are right about the physical process but we are going to assume that a powerful negative feedback will come along any day now and cancel out most of the warming'. That's still crazy, but at least it would match the actual scientific position of the remaining 'skeptics'.
  3. Glaciers are growing
    Henry, don't you think the title of Carlisle's work is a little, well, ignorant? Decline in glacial mass is not cited as evidence for the theory of AGW. No scientist would say, "glacial mass is declining and this proves AGW." Carlisle: "Glaciers are influenced by a variety of local and regional natural phenomena that scientists do not fully comprehend. Besides temperature changes, glaciers also respond to changes in the amount and type of precipitation, changes in sea level and changes in ocean circulation patterns. As a result, glaciers do not necessarily advance during colder weather and retreat during warmer weather." What a revelation. Glaciers "do not necessarily" shrink or grow in response to changes in global temp, but in general they do, as evidenced by the change in global mass balance. The analogous situation is global sea ice. Area of both poles are subject to regional fluctuations from year to year, but Arctic extent, area, and volume are, across the entire Arctic region, rapidly decreasing. Antarctic sea ice extent is slightly increasing, even while ice shelves show signs of increasing deterioration.
  4. Pal Review - the True Story and the Fairy Tale
    Whoa, I must have just engaged in time travel, responding to CBD's comment a half hour before he made it!
  5. Pal Review - the True Story and the Fairy Tale
    CBD @27 - at one point a couple years ago Roy Spencer did question whether the CO2 increase was anthropogenic, on his blog. I don't know whether his position on the subject has changed since then though - I would certainly hope so. Spencer does acknowledge that the CO2 increase is causing warming though.

    Fabulous work, Kevin, both in your analysis and presentation. Found a typo in paragraph 5: "but not the Antartic coverage bias." ... s.b. "Antarctic".

    Rufus9 wrote: "So from my perspective, when I see Dikran's comment that seems to question "any paper that argues that the rise in CO2 is a natural phenomenon", it triggers my skeptical self-defense mechanism." As long as the same skeptical self-defense mechansim swings into action if someone claims that the rise is not anthropogenic ;o) Seriously, there are very good reasons why the possibility of a natural cause can be effectively ruled out completely. It is a subject I have looked into in some depth and even ended up writing a peer-reviewed comment for a journal on the subject. I'd be very happy to go over all this with you in detail on a more appropriate thread, e.g. this one.

    A drop in volcanic activity caused warming
    Henry Justice, Perhaps this is a better thread to raise your volcano questions. (I could not find an ice and volcano thread). I suggest that you calculate how much energy a volcano emits and compare that to how much energy it takes to melt a gigaton of ice. You will find that even if there is a volcano in the middle of an Antarctic glacier the melting it causes is not significant. The energy imbalance in the Arctic is equal to hundreds of unknown volcanoes (would so many volcanoes cause seismic activity?). In keeping with your posts I have provided no references, that is your responsibility.
  10. Carbon Pricing Alarmists Disproven by the Reality of RGGI
    I'd also point out that Norway has had a carbon tax since 1991. Apparently it's made a difference relative to business as usual, of up to ~10%. But its emissions still increased: this could be due to sheer wealth or due to the parts of the economy that aren't included. Norwegian GDP has increased ~200% since the carbon tax was introduced.
  11. Carbon Pricing Alarmists Disproven by the Reality of RGGI
    @ actually thoughtful The update is that not much has changed. This year will see the last legislated increase in the rate of the carbon tax. The current political mode (in which the governing Liberals who introduced the tax find themselves in trouble for reasons unrelated to the tax) means that the tax will stay at its current level of $30/tonne for the foreseeable future. Or at least until the next election in 2013; one new political party has vowed to kill the tax if they get elected and there is a chance that might happen. As for what the tax has achieved, that is harder to say. The last BC GHG inventory only has data for 2009 and earlier. The next report to be released some time in 2012 will cover emissions from 1990-2010. The inventory report does show a slight drop but that could easily be due to the global recession. On the plus side BC's gasoline consumption has dropped by three per cent compared to the rest of Canada. This could reasonably be attributed to the carbon tax But like I said in the original article the tax is still too small to have any real effect on emissions, but there is only so much a single jurisdictional can do to price carbon before it begins to export industries that have high emissions (which doesn't do anything to lower global emissions). What the BC carbon tax has demonstrated is that properly designed and implemented revenue neutral carbon tax doesn't in fact hurt the economy, despite what some critics would have you believe.

    Pal Review - the True Story and the Fairy Tale
    Rufus9 It's OK to be skeptical, but you shouldn't be reflexively cynical of all of science based on a few select audits. That is equally naive, in my opinion, and it produces a false equivalency. As your Begley article shows, it is possible, with due deliberation and experimentation to separate the wheat from the chaff in published science (although he oddly dissociates himself from the whole scientific process by tying himself down to non-disclosure agreements.) Thus, it is not because of one flawed paper that that humans are believed to be the cause of the rising CO2. There are in fact many papers using different lines of evidence that come to the same consistent conclusion. The analyses rest on basic principles that have served us well for centuries, like conservation of mass, radioactive decay, dissolution chemistry, etc. To question the role of humans in CO2 would be akin to challenging these principles. Similar statements could be made for the evidence for increasing surface temperatures, the role of CO2 as a greenhouse gas, and the role of greenhouse gasses in current warming. I think Begley would applaud this kind of reproducibility. The same cannot be said of skeptic papers. They typically do not address the larger body of data and the implications of their findings, choosing instead to focus almost exclusively on details that appear at first blush to cast doubt on one aspect or another of AGW. When analyzed properly or placed in context we see over and over that they do no such thing. The mistakes and the bias are often so obvious that any reasonable review process should have uncovered them. That is dana and John's point...they were forced to engage in pal review to get through peer-review. It is exactly this kind of thing that Begley is decrying in your example.
  13. Pal Review - the True Story and the Fairy Tale
    Rufus9: Let's look at it another way: Michaels et al have accused the mainstream scientists of "pal review", arguing that friendly reviewers and editors make it easy for the "pals" to get papers published with the "accepted" viewpoint. If we accept that this is true, then we can ask the question, "What would we expect to see as a pattern in the publishing of papers by this group?" I think we'd expect to see: - more papers by the "pals" appearing in "friendly" journals than in "unfriendly" journals - a higher ratio of papers from "the pals" appearing in these journals than papers by "outsiders" (in the same journals) Do we see evidence of this? Yes we do, but it is in the papers from the skeptics that we see the evidence, not in the rest of the discipline. To say that this pattern exists in the authors outside of the "skeptics" group, you'd have to argue that the "pals" control virtually the entire publishing industry, and that gets you into fairy-tale conspiracy theories, not objective evidence. As is pointed out by John Mashey, feel free to search for such evidence, but it will have to be as strong as John's evidence is against the "skeptics" to have any hope of turning the pointer away from the "skeptics" and towards the mainstream consensus position. Are we certain? No, but there is more evidence to support Michaels et al of this behaviour than there is to support saying this about the mainstream scientists. Neither is certain, but we're a lot less uncertain about the "skeptics". As for the statement of Dikran's about "any paper that argues that the rise in CO2 is a natural phenomenon" - I agree with him completely. At this point in the science, to think the rise is not due to humans burning fossil fuels is pretty close to claiming that falling objects are not under the influence of gravity. Most of the rest of your discussion appears to be of the form "we don't know everything, and aren't always right, so I get to act as if you know nothing and you're always wrong".

    Oh, boy. Be on the lookout for deniers cherrypicking data on this one. Delawarre and Maryland saw electricity bills increased by 22% and 29%. Also Rhode Island's unemployment rate increased by 4,7%, much more than the US average. Plenty of room for cherries.

    Tom Curtis at 22: "you are assuming that Otzi died in an ice free area that later became glaciated." Here is what I stated: "Does this indicate the present melting of the glaciers are now back to the level where they were when this mummy was first frozen?" This does not state or indicate an ice free area!

    Dan Moutal its been over a year since your article - is an update in order? Using individual states and regions as a test case for the concept makes sense, and now that the data is coming in, at a minimum it proves the ideas work, and seem to provide some evidence for the case I have been making - the non-monetized benefits of renewables exceed any nominal cost, and indeed, renewables are, even at face value, cheaper than fossil alternatives.

  20. Pal Review - the True Story and the Fairy Tale
    Bad science gets published all the time, no doubt about it. The question is though whether there is any good science published at all that seriously challenges modern climate theory? The "skeptic" papers are mostly very bad science that can only get published in journals with low standards or via pal review. The perception is not helped by dubious paper sneaking through (McLean et al, Soon & Baliunas) which are then trumpeted in press statements as saying (incorrectly) more than in fact is possible.
  21. Today's Climate More Sensitive to Carbon Dioxide Than in Past 12 Million Years
    Martin @13, it is not clear how, and to what extent Knorr et al, 2011 disagree with LaRivierre et al, 2012. Knorr et al. discuss the mean global temperature in the Late Miocene rather than just the NH mid latitude Pacific as discussed by LaRivierre et al. Therefore there is may be no contradiction between their respective estimates of the temperature anomaly, ie, 3 Degrees C for the Global Mean Temperature Anomaly by Knorr et al, compared to 5 to 8 degrees C for part of the NH Pacific Ocean for La Rivierre et al. Like wise, the explanation for the anomalous global warmth may well be, primarilly, changes in albedo; while the explanation of the greater anomalous warmth in the NH Pacific may well still be ocean currents, as it is a different (although related) phenomenon. However, yes, the science of Mioncene climate is certainly unsettled. This is not because of a problem with the physics of climate, however. The same physics which predicts rising temperatures with increasing anthropogenic emissions can explain the anomalous warmth in the Miocene, as is shown by Knorr et al. What makes the science of Miocene climate unsettled is the restricted observational data set. To give one example, LaRivierre et al rely on just two data sets for their analysis of Miocene CO2 levels. One is an analysis of alkenones by Pagani et al, 1999 showing just 33 observations over the 7 million years discussed (panel a): The other is from Pearson and Palmer (2000), which shows just six observations over the 7 million years: (Note, I have set the CO2 concentrations as determined by Pagani et al as background for comparison.) With such limited information, several hypotheses may remain consistent with the data. Of course, those several hypotheses are consistent with the physics of the greenhouse effect as determined from better observed times. No doubt, of course, we are about to see an entertaining display from the fake "skeptic" community as they take the limited and partially conflicting observational data from the Late Miocene as being above reproach so they can falsely claim a counterexample to the known physics; while of course they insist the thousands of modern direct measurements with thermometers are not an adequate basis to determine that the Earth is warming.
  22. Pal Review - the True Story and the Fairy Tale
    John - nice admission that "... we really don't know." What is true of your study as well as many others is that it has established correlation but not causation. As such, the results are sufficient for generating hypotheses, but not "proving" anything (I'm not saying that was your objective). Similarly Dana notes that " Michaels for example got 7 published in CR and 7 published in other journals at the same time." Without some additional information, it is hard to know how to interpret that statement. Does it mean that there were 7 other journals that were also susceptible to "pal reviews", or does it lend credibility to Michaels because he was also published in those other journals. Once again, we can generate a hypothesis, but cannot prove it one way or another based on your work. If you listen to the Econtalk podcast I linked previously, there is a very good discussion of the pitfalls of scientific studies, and we should not be so naive to think that bad research is limited to once side of the climate debate or the other. As Dikran (14) noted, "The major problems with peer review is the "publish or perish" nature of academia, which means there is great pressure on all of us to publish in quantity often at the expense of quality. This is becuase it is hard to make an objective metric that measures quality (at least hard to make one that operates without a delay of 5+ years). This means that (i) there are many more papers published than there used to be (ii) academics have less time to review them than they used to do (iii) comments papers have little or no value, so academics have pretty much stopped writing them. The result is an explosion of the number of journal and a reduction in quality control." In other areas of science, for example cancer research, it was recently discovered that 47 of 53 "landmark" studies could not be replicated, and yet they were cited over 200 times by other researchers. http://blog.sethroberts.net/2012/04/03/lack-of-repeatability-of-cancer-research-the-mystery/ Quote from a Reuters article: "During a decade as head of global cancer research at Amgen, C. Glenn Begley identified 53 “landmark” publications — papers in top journals, from reputable labs — for his team to reproduce. Begley sought to double-check the findings before trying to build on them for drug development. Result: 47 of the 53 could not be replicated." So, while we might expect there to be some honest error in any field of research due to the limits of knowledge, an 88% non-repeatability rate is certainly shocking. Does this extend into other fields of research? It most certainly does. I'm a big fan of Gary Taubes, whose work often highlights flawed research in the area of nutrition and health. (he's written in other areas as well). For an enlightening view into this world, I suggest reading "Do We Really Know What Makes Us Healthy" or, more recently, his commentary on Harvard's latest "correlation study" showing the supposed dangers of eating red meat (which has been severely critiqued upon review of the actual data). See garytaubes.com So from my perspective, when I see Dikran's comment that seems to question "any paper that argues that the rise in CO2 is a natural phenomenon", it triggers my skeptical self-defense mechanism. It does not matter to me if Harvard says red meat causes increased mortality or if a stack of 500 climate research papers supports the AGW theory because it is simply naive to believe that all of those papers are correct. And, if 5% or 10% or 88% of them are flawed or not repeatable, then the skepticism is warranted. I think you've actually done some interesting work, but at the end of the day, as you said, we don't know.

    Hey, the Brazilian president on the toon of the week! That doesn't happen very often. BTW, is there an online source with a list of emission targets and actual emissions of each country? The most recent Brazilian emission inventory I've found has data from 2005.
  24. Fred Singer Promotes Fossil Fuels through Myths and Misinformation
    NSherrard - while speculation is big on volatility in oil pricing, the line that the price wriggles around is dependent on production versus demand. Production can be producer whim but also under-investment in new production as older production peters out which is certainly a problem in Middle-East/North Africa at moment. Of course, getting new production on stream gets harder all the time. However, since problems with production/demand in oil will only get worse, and since there is only so much damage we can do to climate via petroleum, the real issue for climate is coal.

    Fred Singer Promotes Fossil Fuels through Myths and Misinformation
    Dana and Phillippe, I think arguing the semantics of "theory" and "proof" is the wrong approach to take with Mr. Rauch, and will probably just leave him rolling his eyes in exasperation, feeling that you are missing the point. The fact is that he said that global warming was "at best" an unproven theory, suggesting that he dismisses all aspects of the science, not merely its certitude. In that event, I would suggest that a better approach with Mr. Rauch would be to point him towards the wealth of information available here, along with the fact that the only people who contradict the position of every major national science academy in the world is a small, loud, vocal cadre of outliers and an equally loud cadre of PR firms and personalities (Forbes writers, not-exactly-lobbyists, weathermen, not-exactly-Lords, etc.). Just because they have his attention, and keep hammering their misinformation at everyone who will listen, does not make what they are saying true.

    Fred Singer Promotes Fossil Fuels through Myths and Misinformation
    "there are myriad reasons to begin adopting alternative energy resources" Most definitely. It is plain that fossil fuels of all kinds will be exhausted if mined to, well, exhaustion. Then what? This question by itself is enough reason to do all the work we need to do to get away from fossil fuels, now that we are enjoying the unprecedented comfort and ease of living that these same fuels have allowed and that we can afford to do that work. We have a small window of opportunity; with billions of people wanting to enjoy the good life like we do in the West, it will not last very long, and the aftermaths of the big carbon release will call for some serious flexibility on our part.

    Fred Singer Promotes Fossil Fuels through Myths and Misinformation
    I think Marc Rauch is right, that there are myriad reasons to begin adopting alternative energy resources. There are national security issues, domestic jobs issues and many other fantastic and meaningful reasons. But I believe he is misguided in his desire to see AGW and alternative energy sources to be separate issues. The science for man-made warming is overwhelming, and very often it's very difficult to convince people in his position of this. I think there is extreme exasperation within the scientific community to find ways to explain to people like Mr Rauch exactly how overwhelming the research is. There is no doubt at all that man-made greenhouse gases are warming the planet. There is no doubt that reduction of those gases is absolutely necessary. There are uncertainties with regards to how severely the planet will respond but even the lower estimations are very concerning. How to make this clear to people like Mr Rauch is an issue that is keeping lots of scientists awake nights.

    Fred Singer Promotes Fossil Fuels through Myths and Misinformation
    Mr Rauch, I certainly do not want to impinge on SkS comments policy that precludes "dogpiling." However, I have to point out, seconding Dana, that "unproven theory" in the context used in your post indicates a lack of understanding of what a scientific theory is. Quantum theory is also an "unproven" theory, whose implications are at odds with the General Relativity theory. Yet both of them are very successfully applied together in GPS, where electronics put Quantum to use, and where General Relativity allows for the accuracy that newtonian physics would not permit, considering the velocities and distances involved. It should be noted, however, that Relativity did not disprove Newtonian physics, only changed its domain of application. A scientific theory is not a hypothesis. This misunderstanding appears to be common in the US because of the pervasive deceitful argument made by creationists that "Evolution is only a theory." It works well with that part of the public that does not understand the difference between theory and hypothesis. The consensus model of Earth climate as it has been experienced by Humans is a well supported theory, not a hypothesis.
  29. Fred Singer Promotes Fossil Fuels through Myths and Misinformation
    Mr. Rauch, first of all, all scientific theories are unproven because theories cannot be proven. Saying "unproven theory" is redundant. It's also no different than saying "evolution by natural selection is just an unproven theory." Secondly, the best case for supporting alternative fuels is that they are a key solution to human-caused global warming, which is one of the greatest threats humanity has ever faced. Bringing up absurd conspiracy theories of 'fraud' and the like only harms the case for alternative fuels. While you might prefer that the two issues be treated separately, that's not going to happen. Most of the people who oppose alternative fuels oppose climate science for the exact same reasons.
  30. Carbon Pricing Alarmists Disproven by the Reality of RGGI
    Remember here in British Columbia we have had a carbon tax for the past several years. And if the economy was destroyed, I haven't noticed. I even write an article about it here as sks.
  31. Fred Singer Promotes Fossil Fuels through Myths and Misinformation
    One of the biggest problems with acceptance of alternative fuels and energy is that so-called man-made global warming has been lumped together with it. If man-made global warming is real and if the use of non-fossil fuels would impact the effects of global warming then there would be a reason to put the two issues together. But, even if man-made global warming is happening, there is nothing but conjecture to support the theory that alt-fuels can mitigate it. However, there are sufficient good reasons to support the wide-spread use of alt fuels without taking into account man-made climate change. In fact, because man-made global warming is at best an unproven theory, tying the two issues together drastically hurts alt-fuel acceptance. The issues should stand on their own, which I believe would make arguing for alternative fuels much easier and more palatable for the vast majority of people who believe that man-made global warming is a fraud. On the other hand, if man-made global warming is real, and if the production and use of non-fossil fuels are a helpful solution, then fine, both issues are addressed. But if we can get alt-fuels accepted then everyone wins. Marc J. Rauch Exec. Vice President THE AUTO CHANNEL
  32. Today's Climate More Sensitive to Carbon Dioxide Than in Past 12 Million Years
    @12 Tom Thanks for posting Knorr et al. It seems to me that Knorr disagrees with this nature article regarding the causes of a warm, low CO2 Miocene world. Knorr emphasizes a change in albedo due to a change in vegetation distribution whereas the Nature article focuses on changes in ocean circulation. I'm tempted to believe that the science isn't settled at least with respect to the Miocene.

    Fred Singer Promotes Fossil Fuels through Myths and Misinformation
    NSherrard, most of the (very large) volatility in the price of the oil barrel is owed to speculation. "Pure" oil speculation consists of buying and selling oil without ever taking possession of a single drop of it. It does, in fact, represent a problem for the purpose of working our way out of oil dependence. Right now there is no political will to regulate the parasites cashing in on the system without adding any value to anything. As push comes to shove, which will inevitably happen, low-hanging fruits for easing oil prices will be picked first and the enormous speculation will be eliminated, giving everybody the impression that oil is cheap and pllentiful again, for a little while. As with other kinds of speculation, it is a far greater threat to economies than any large scale action to curb GH gas emissions. As a matter of fact, it is easy to demonstrate that the behaviors of the important actors of Wall Street and other big markets are largely responsible for every major depression or recession that has happened since, and including, the Great Depression.
  34. Fred Singer Promotes Fossil Fuels through Myths and Misinformation
    Slightly off-topic, but related to the post, how can the increase in crude oil price from $35 a barrel in 2004 to $144 a barrel in 2008 have anything to do with "unrest in Libya and elsewhere in the Middle East" which began in December 2010? The price and future (and future price!) of oil is inextricably linked to the fate of our climate. I have not yet seen a satisfactory explanation from any government report of the behavior of the price of oil over the past decade. Someone somewhere is obfuscating.

  36. Carbon Pricing Alarmists Disproven by the Reality of RGGI
    MarkR @1 - yes we certainly can't tease out the exact effects of the carbon pricing system on the RGGI states' economies. However, as noted in the post, the contrarians like Monckton and the Koch brothers have said that these types of systems will spell doom for the economies of whatever states and countries implement them. That is pure alarmism, as RGGI demonstrates. Of course as with all climate myths, the fact that it is disproven by reality won't stop the contrarians from continuing to make the argument.
  37. Don Easterbrook's Heartland Distortion of Reality
    Hi Tom @5, Yes, that is a good read and exposes more of the errors and misrepresentations in Easterbrook's talk. It is hardly a surprise that shoddy "science" is being presented at Heartland "climate" conferences, but still importnant to document.
  38. Carbon Pricing Alarmists Disproven by the Reality of RGGI
    John, technically yes... but in reality most retirees pay no income tax because the deductions are greater than the tax which would be due. The exceptions are usually cases where some other form of income is still coming in. Also, most states do not subject social security returns to income tax.

  40. Carbon Pricing Alarmists Disproven by the Reality of RGGI
    MarkR, I think I can safely say that most of the American people aren't paying enough attention to be insulted. Last year the GOP came out with a bit about half of all Americans paying no taxes (really income taxes, but they always seem to forget to include that word). It was a big deal with angry rants on major 'news' programs. I felt horribly embarrassed for the retirees brought on the shows to denounce these "filthy leeches"... not realizing that they constituted the majority of the people in question (i.e. they're retired... they have no income... ergo no income tax). The vast majority of Americans have no idea what is going on and just accept whatever their chosen party tells them... even when that is directly at odds with what the party was telling them last year. Thus, the fact that reality proves the 'carbon pricing will destroy the economy' claims to be complete nonsense doesn't really matter. A good deal of what the people who believe that hold to be true is complete nonsense. They aren't about to change now.
  41. Carbon Pricing Alarmists Disproven by the Reality of RGGI
    In the US the fossil fuel lobby has been saying that any climate action would be too expensive and ruin the economy. Since the US was recently around 20 tons CO2 per person and European nations around 10 tons (France ~6 and UK ~10 iirc?) the argument from the lobbyists is basically 'America is so incompetent compared to Europe that if we gave ourselves 30 years to match what they're already doing, it would destroy America!' Which is ridiculous, America isn't the useless incompetent country that the lobbyists are trying to persuade the people & politicians it is. I'm surprised the American people aren't more insulted.
  42. Carbon Pricing Alarmists Disproven by the Reality of RGGI
    I think the important thing we can take from this is that these data aren't enough to say whether the policy cost x% or had benefits of x%. the alarmist claims about demolishing economies are obviously far wrong.
  43. Today's Climate More Sensitive to Carbon Dioxide Than in Past 12 Million Years
    Perhaps Knorr et al, 2011 will help put the above article in perspective:
    "Proxy records from the Miocene epoch (∼23-5 Ma) indicate a warmer climate than today in spite of lower atmospheric carbon dioxide (CO2) concentrations in the range of preindustrial levels. As yet the simulation of a warm Miocene climate with these low CO2 values has proven to be a challenge. In this study we present climate simulations of the Late Miocene (11-7 Ma) with a preindustrial CO2 level, using a coupled atmosphere-ocean general circulation model (AOGCM). The simulated global mean surface temperature of ∼17.8 °C represents a significantly warmer climate than today. We have analyzed the relative importance of tectonic and vegetation changes as forcing factors. We find that the strongest temperature increase is due to the Late Miocene vegetation distribution, which is more than three times stronger than the impact induced by tectonic alterations. Furthermore, a combination of both forcing factors results in a global temperature increase which is lower than the sum of the individual forcing effects. Energy balance estimates suggest that a reduction in the planetary albedo and a positive water vapor feedback in a warmer atmosphere are the dominating mechanisms to explain the temperature increase. Each of these factors contributes about one half to the global temperature rise of ∼3 K. Our results suggest that a much warmer climate during the Late Miocene can be reconciled with CO2 concentrations similar to preindustrial values."
    Also, for reference, here is the abstract of the article referred to by the OP.

    Martin @ 7... CO2 is the "biggest" control knob, not the only control knob.
  45. Today's Climate More Sensitive to Carbon Dioxide Than in Past 12 Million Years
    Point of clarification:
    "The Miocene is a geological epoch of the Neogene Period and extends from about 23.03 to 5.332 million years ago (Ma). The Miocene was named by Sir Charles Lyell. Its name comes from the Greek words μείων (meiōn, “less”) and καινός (kainos, “new”) and means "less recent" because it has 18% fewer modern sea invertebrates than the Pliocene. The Miocene follows the Oligocene Epoch and is followed by the Pliocene Epoch. The Miocene is the first epoch of the Neogene Period. The earth went from the Oligocene Epoch through the Miocene and into the Pliocene as it cooled into a series of Ice Ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regional boundaries between the warmer Oligocene and the cooler Pliocene. The plants and animals of the Miocene were fairly modern. Mammals and birds were well-established. Whales, seals, and kelp spread. The Miocene Epoch is of particular interest to geologists and palaeoclimatologists as major phases of Himalayan Uplift had occurred during the Miocene Epoch affecting monsoonal patterns in the Asia, which were interlinked with Northern Hemisphere glaciation."

  46. Pal Review - the True Story and the Fairy Tale
    Dana: think of how many papers Michaels could have gotten published elsewhere if there wasn't a conspiracy against him! Seven per journal, dozens and dozens of journals. ;-)
  47. Today's Climate More Sensitive to Carbon Dioxide Than in Past 12 Million Years
    The study explains a wider local effect in a narrow period some 12 million years ago. So what? Interesting is the clue about the increased sensitivity which has been stromg for more than 500,000 years. More important: For more than 20 million years the planet hasn't shown higher CO2 concentrations than the rapidely rising current ones. At that stage earth was about six Celsius warmer!
  48. New research from last week 20/2012
    Perhaps this should be edited in light of the recent developments in the Gergis paper.

    @1 Dave - I am eagerly awaiting the future denialists (in Europe) commenting on that finding ... we'll see
  50. Pal Review - the True Story and the Fairy Tale
    Ah but Bob, while the pals got a great many papers published in CR during this timeframe, they were also able to get papers published elsewhere. Michaels for example got 7 published in CR and 7 published in other journals at the same time.
