  2. How I lived through a carbon tax and survived to tell the tale
    Gilles#217: "high extractions costs have reduced emissions ! It's very clear that the production of FF has leveled off during the spike of barrel price" By 'the spike,' I take it that you mean 2007-2008. Yet your graph shows that production leveled off in 2005. Unless we have some kind of time-travel inverting causality here, I'm not sure how you accomplish this. How do you translate the spike, a short-term event (by the definition of the word 'spike') to a reduction in emissions, which did show a measurable decrease until the recession of 2008-2009 flatlined economic activity? And what, exactly, does increased price paid to a producer per barrel of oil have to do with extraction cost? Friendly word of advice: Until you have some legitimate understanding of the oil business, you really should stop believing everything you read on the peak oil blogs. Or at the least, apply some of the finely honed skepticism that you've displayed here.

  4. A Plan for 100% Energy from Wind, Water, and Solar by 2050
    Daniel Maris- Certainly, the UK and other countries should exploit renewables to the best of their abilities. However, this 100% renewables goal simply won't materialize, and even if it does, the timeframe would've been so large that it would've been an idealogical reject-everything-that-isn't-renewable campaign that turns down other solutions (like nuclear), which would most likely take longer and cost more than using renewables and other solutions (like nuclear) combined. Let's examine the three worst commercial nuclear accidents: Tsjernobyl is what happens when you try to outcompete and outproduce a wealthier neighbor, and then shut down the cooling system in a testosterone moment. The United Nations Scientific Commitee on the Effects of Atomic Radiation places the death count (including cancer deaths) at 62 as of 2008 http://www.unscear.org/docs/reports/2008/Advance_copy_Annex_D_Chernobyl_Report.pdf Three-Mile Island resulted in zero deaths and was blown vastly out of proportion. Fukishima is what happens when you hit an old reactor with a level 9.0 earthquake and a 17-meter tsunami. The plant should've been decommissioned a decade ago, and none of Japan's 54 other nuclear plants had similar problems. And nobody died. Many reactors that are built today utilize what's known as passive-safety, in which the reactor can cool without mechanical failsafes. Several reactor types that use this include Integral Fast Reactors, pebble-bed reactors, pool-type reactors like TRIGA, certain breeder reactors, etc. Interestingly, India and China are doing much of the research for us; we'll see in 2030 whether their nuclear economies are superior to renewable economies.
  5. Christy Crock #3: Internal Variability
    John C. and Dana, "As John sometimes says, they have to explain why the increased greenhouse effect isn't warming the planet significantly, and why their alternative is warming the planet exactly how we expect GHGs to warm it. " That quote is a great assessment. A keeper for sure.
  6. There is no consensus
    Bruce, I would characterize science is learning to use data to overcome our biases. Some non-scientists learn this; some scientists dont. Overturning AGW is straightforward at one level. Current climate theory (from which AGW is a consequence) makes a huge no. of predictions. If reality turns out different using both the margins of errors in data and margins of error in the prediction, then the theory must be modified. Of course, even more convincing would a different better theory that explained all current observations and had stronger predictive power. Nothing doing so far on either front, but who knows? Convince me. So, care to tell us what data would it take to change your mind? What's the point at which you decide that you are wrong?
  7. How I lived through a carbon tax and survived to tell the tale
    @ Gilles " And tar sands production hasn't risen - for the good reason that nobody wanted to buy more." I couldn't let this slide by. It is absolutely false. The Tar sands are still booming. In fact The US just opened up its first tar sand operation. People are still addicted to oil. Demand is as high as it ever was.
  8. Monckton Myth #16: Bizarro World Sea Level
    WSteven: I know education standards are often considered to be slipping, but I'd hope that anyone who tried that trick even in junior high would be slapped down with a big fat 'F'... It puts me in mind of that famous quote popularised by Adam Savage from Mythbusters: "I reject your reality, and substitute my own."
    Moderator Response: [DB] Then you'll like this reality.
  9. How I lived through a carbon tax and survived to tell the tale
    @ Gilles The mods are right of course, but are still only looking at part of the puzzle. Oil isn't the only FF. Coal is also an issue, arguably an even bigger one than oil. And as oil prices have risen more than a few people have contemplated coal liquefaction, which absent a price on carbon would release even more GHG emissions. And we are still only looking at the liquid fuels part of the problem. High fossil fuel prices mean that more unconventional fossil fuels become economically viable, and in many cases (like the examples above) they are dirtier than the conventional fuels they replace. Hence why a price on carbon emissions is essential to lowering GHG emissions. Otherwise one can have both rising FF costs AND rising emissions. All of this was explained in the interviews I posted. Please listen to them, you can learn a lot from someone who has spent a great deal of time thinking about the issue.
  10. Christy Crock #3: Internal Variability
    "There was never any reason to think that it would increase temperatures." Not only that, but volcanoes also put up far, far more aerosols-into the stratosphere-than they do CO2, so leading to an overall *cooling* effect in the troposphere (but a warming of the stratosphere).
  11. Christy Crock #3: Internal Variability
    Alexandre - those are all valid questions. It gets to the point we made in the post that there are a number of 'fingerprints' which AGW can explain but which internal variability cannot. As John sometimes says, they have to explain why the increased greenhouse effect isn't warming the planet significantly, and why their alternative is warming the planet exactly how we expect GHGs to warm it. cloa 513 - please see "it's cosmic rays" and "climate sensitivity is low" where we show both your comments are incorrect.
    Response: [John] Actually I haven't published that article yet, it's due out on April 28 :-)

    Albatross:"Re credibility seppuku-- that is not a comment or opinion, it is an empirical observation based on your posts here. You are entitled to your opinion, but do not expect to overturn credible science or make compelling arguments by talking through your hat." What are you talking about? If I am objectively trying to overturn science, what science am I trying to overturn? Please be *specific* because I *don't know* what you mean. Is there a reference which says that we can represent all indirect solar forcings as multiples of TSI? I am unaware of such, and, frankly, if there is such a reference you would be better off just providing it rather than continuing to make unsupported claims.

    Christy Crock #3: Internal Variability
    "There is low CO2 temperature climate sensitivity- the reaction of the temperatures to major volcanic eruptions shows that." Major volcanic eruptions have a tiny impact on the amount of CO2 in the atmosphere. Pinatubo for instance released about 1/30 as much CO2 as we did that year. There was never any reason to think that it would increase temperatures. There was plenty of reason to think it would temporarily lower temps because of the ejection of aerosols into the stratosphere; this was predicted before hand and the models showed excellent agreement with the subsequent cooling.

  15. How I lived through a carbon tax and survived to tell the tale
    "you just forget something : we already have cars." Wow, is that the *best* you can do? Hilarious. In the 19th century, we already had a number of relatively cheap modes of transportation (horses, horse-drawn carriages, bikes, our own two feet). Yet that didn't stop the public & private sectors from collectively investing in the construction & sale of very expensive motor cars-or the construction of an entire fuel infrastructure. Similarly, when TV's first came out, we already had access to a number of relatively cheap entertainments (the radio, the theater, the movies). Yet, again, that didn't stop the manufacture & sale of relatively expensive TV sets-or the construction of an entire infrastructure to make us of the new medium. Now of course most renewable energy sources aren't starting off nearly as expensive-relative to existing energy options-as cars & TV's were relative to their pre-existing "competition". The *real* point of my analogy, though, was that once economies of scale got going, both cars & TV's (& coal-fired electricity for that matter) all came down in price until they were affordable to the masses. In the same vein, the life-cycle costs of renewable energy technologies will continue to improve as economies of scale (& improved manufacturing technologies) kick in. Meanwhile, increasing scarcity of fossil fuel resources will make the life-cycle cost of coal-fired electricity even more expensive. So much so that I feel confident in making the following prediction-the nations which have failed to make a switch towards a *mostly* renewable energy fueled economy, by around the middle of this century, are setting themselves up to the Third World Countries of both the latter half of the 21st century & the 22nd century.
  16. Christy Crock #3: Internal Variability
    Both wrong- its external variability- cosmic rays (and the sun) explain the cloud cover. There is low CO2 temperature climate sensitivity- the reaction of the temperatures to major volcanic eruptions shows that.
    Response: Problem with the "cosmic rays are driving global warming by changing cloud cover" argument is cosmic radiation and climate went in opposite directions in the latter 20th Century - if anything cosmic rays and the sun should be having a cooling effect.

  17. Christy Crock #3: Internal Variability
    Christy dismisses all the evidence supporting AGW as insufficient, perhaps. I would guess that his own theory has a much more compelling set of evidences. But it fails to answer a lot of questions: - Why did DLR increase and OLR decrease over the last decades? - Why did this measured trapped IR energy NOT increase the temperature? What has happened to it? - Where’s the very compelling evidence that global temperatures vary as wildly as the last decades (some 0.6ºC in 40 years). Why did all those clouds decide to warm the planet now, if they don’t usually do it? - Where’s the evidence that cloud cover has varied as much as to justify the observed warming over these decades? I’m a layman, so I’d be pleased if someone more knowledgeble explained to me why my questions are for some reason irrelevant. Or not?
  18. It warmed just as fast in 1860-1880 and 1910-1940
    42, Rob, Wow. Okay, so this guy has a really, really deep bag of scientific "tricks." And the deniers are all up in arms about "hide the decline?" Sheesh. Adam, Sorry, but as a source, that one is downright pathetic. Please check your sources more carefully in the future. If you don't mind taking a bit of advice, usually I find it helpful to be skeptical about these sorts of things, read them carefully, and look into them in some detail. Otherwise you could find yourself falling for some very alarming scientific hoaxes.
  19. Monckton Myth #16: Bizarro World Sea Level
    I love the tilted graph. I'd expect that kind of nonsense from someone in junior high or _maybe_ senior high school. How can anybody who does this be considered a credible source of information? Good article, Dana.
  20. It warmed just as fast in 1860-1880 and 1910-1940
    All, Re the dubious TSI data from Soon. Here is a graph by Kopp and lean (2011; both (eminent scientists in this field) that shows a distinct downward trend between 1979 and 2010: Caption: Contributions to the empirical model of temperature shown in Figure 1 are broken down here: El Niño Southern Oscillation (purple), volcanic eruptions (blue), anthropogenic effects (red), and solar irradiance (green). [Source] and compare those data with the SAT data: Caption: Global surface temperature from 1980 to 2010 has risen by 0.4 degrees Celsius (0.72 degrees Fahrenheit) according to Climate Research Unit measurements (black) and an empirical model (orange). (Courtesy Kopp and Lean), same source as above. Not surprisingly, Kopp and Lean conclude that: "Using this model, Lean estimates that solar variability produces about 0.1°C global warming during the 11-year solar cycle, but is not the main cause of global warming in the past three decades."

    Weather vs Climate
    Bruce@124 If you think there is anything interesting in that, you have just demonstrated that you don't understand the difference between weather and climate. A warming climate does not imply there will not be bad weather, there isn't anything ironic about it. Dellingpole shows rather poor taste in his sarcastic gloating about it IMHO, I don't know why anyone would want to share in that.

    Weather vs Climate
    Climate vs weather. A group of activists headed up to the arctic circle in May 2009 to "raise awareness" that the "warmer climate" was creating mild snow, ice, and temperature conditions there, thus driving polar bears to extinction. They were driven back by ferocious snow, ice, and temperature conditions that nearly killed them; they needed to be rescued lest they die under the horrific cold conditions they found on the way. The number of polar bears they encountered was posing yet more deadly risk to the party. It incident was all due to colder "weather" and not the warmer "climate" http://blogs.telegraph.co.uk/news/jamesdelingpole/9802307/Global_warming_explorers_in_Arctic_get_nasty_shock_polar_ice_caps_blooming_freezing/
    Moderator Response: Yes exactly, as you pointed out this is an example of weather not climate. If your argument is that the arctic is not warming, please take it to one of the related Arctic threads posted here.
  23. How I lived through a carbon tax and survived to tell the tale
    "The reason why high extractions costs wont reduce emissions has already been answered. (hint tar sands)" The issue is that high extractions costs have reduced emissions ! It's very clear that the production of FF has leveled off during the spike of barrel price, and will do it again with the current new spike. And tar sands production hasn't risen - for the good reason that nobody wanted to buy more. Personally I'm not fond of "reasons" explaining non-existing facts ...
    Moderator Response: [Dikran Marsupial] ISTR having pointed this out before, but extracting FF from tar sands takes up a great deal of energy. You can't measure total emissions by counting barrels of oil shipped, because that ignores the carbon emissions from energy expended in extracting it. For tar sands, that is very far from negligible. There is also the issue that oil sales are not necessarily driven purely by demand. Oil is not in plentiful or unlimited supply, and it is not necessarily to the economic advantage of those that hold the reserves to sell in such quantities as to satisfy demand. Thus the levelling off of sales does not necessarily imply that the cost of extraction is the cause of the levelling off, or that total carbon emissions are also levelling off. The Earth doesn't care if the carbon emissions are from tar sands oil or from energy expended in extracting the oil from the tar sands. The CO2 is a greenhouse gas either way. Also oil is not the only FF. IIRC also a major justification for tar sands is security of supply rather than cost. Apart from that the comment is fine.

    Monckton Myth #16: Bizarro World Sea Level
    Daniel Maris@30 Would you accept then that the Telegraph article that you raised on another thread has been refuted by the evidence I have presented in this thread, which show the allegations made by Morner are completely without foundation? I ask because a common trait of deniers is to avoid explicitly acknowledging when one line of argument is refuted (so they can return to it later or elsewhere) and simply pick a new line of evidence? What you have just done looks very much like exactly that, so maybe you would like to dispel that impression. Secondly, have you investigated the WUWT story to find out whether it checks out, or whether like the Telegraph article it is full of bogus claims?
  27. There is no consensus
    Bruce@345 "So far I have seen no scientific evidence of any kind here being presented here by anyone." Then you should be doing more reading and less typing. This site is chock full of links to scientific studies and data that support the the premise that the earth is warming and that human activity is driving the change in temperature. Not many people here are practicing climate scientists so not much original work is generated, thus the links to others work. If you have a published paper of your own or links to studies that you think are relevant to the discussion then please post them in the appropriate thread. As for this thread, you have not provided anything constructive to the discussion (not debate! not argument!) of the original post. Your first comment @311 was an accusation that Climate Science is driven by politics rather than data with no supporting evidence. That is not how this site works. If you are going to take a position you need to support it somehow.
  28. There is no consensus
    Hummm two more looong post by Mr. Frykman and still no evidence to back up his earlier claims. Clearly not here to present nor discuss facts.

    Adam... "I have explained why Greenland and Arctic temperature variations are not man made." No, you have explained why you believe there is an inconsistency between the warming period in the early 20th century and the warming in the latter 20th century, making the wrong assumption that both had to be directly correlated with the increased concentrations of atmospheric CO2.
  30. Dikran Marsupial at 08:24 AM on 14 April 2011
    Earth hasn't warmed as much as expected
    Rovinpiper@1 Practically all modern models include ocean effects and are known as coupled atmosphere-ocean general circulation models (AOGCMs). Practically all modern models incorporate aerosols as well (you can't adequately model 20th century climate without them c.f. "ice age predicted in 70s" canard).
  31. The e-mail 'scandal' travesty in misquoting Trenberth on
    Sphaerica : "express exactly where he stands on the topic of this post (i.e. how a statement by an important and respected climate scientist was clearly and manipulatively taken out of context by people who simply don't like what the facts and science have to say). " Frankly ? i don't care much about what people think of what other people say. You may be right , but it's not a question of physics - may be of psychology, politics, sociology. Billions of people think stupid things anyway, so I can't waste my time in looking at them all. So I posted here to correct what I thought being incorrect : no we don't have a precise measurement of fluxes, yes the Earth doesn't seem to have gained energy these last years - whatever the reason is. Read the thread again - I didn't try to "manipulate" anybody - I just explained why some sentences appeared erroneous to me. Alec Cowan : I don't really get what you're trying to argue - yes multiplying 1 W/m2 by the surface of the Earth and the number of seconds in one year gives something like 10^20 J/year - and so? what does it change ?

    Shawn @58, "Just throwing an offhand comment that I am committing seppukku is not helpful.

You are entitled to your opinion, but do not expect to overturn credible science or make compelling arguments by talking through your hat. Re "That may be true, but again, one does not need to invoke GCRs or some other hitherto unknown mechanism to explain the observed warming. Surely you agree with that much?" OK, I think that we finally agree on something--I am referring to the observed warming since the early sixties, when TSI and global SATs traces diverged.

    It seems that Prof Morner isn't safe from ad hominem attacks. I suggest people take a look at this site: http://wattsupwiththat.com/2009/03/19/despite-popular-opinion-and-calls-to-action-the-maldives-is-not-being-overrun-by-sea-level-rise/ You'll see some very interesting photos there which suggest that the alleged sea level rise in the Maldives is really pure fiction. There is also some very relevant criticism of tide guage measurement. Interesting to see the rickety structures - there's only one way they are going and that is down!
    Moderator Response: [Dikran Marsupial] Just for clarification, there has been precisely one ad-hominem against Morner posted on this thread, and it has been deleted by a moderator (not me as I am actively involved in the discussion) because it contained an ad-hominem. So it would seem Prof. Morner is quite safe from ad-hominem attacks here, provided you give the moderators time to do their jobs.
  37. Monckton Myth #16: Bizarro World Sea Level
    adrian, when you read the IPCC carefully you will notice that they _explicitly_ exclude any contribution from melting ice sheets. Not because they think it's a bad idea, or it's not happening, or it can't be measured. It's excluded because of the IPCC's role. To report on the science as published up to a point in time. At the time of collecting and evaluating available papers, there was too little explicit calculation and attribution of the amount or the rate of rise attributable to melt - let alone projections of expected rise due to melt. That situation won't apply for the next round. Don't say you weren't warned if there are big differences between the next and the previous IPCC reports.

Do any of you have any data of figures that substantiate what and who represents this majority? I belong to several groups but I would never be mindless enough to suggest that "group think" constitutes is my think. It all sounds rather militaristic. In discussing all of this science do any of you ever favor one individual scientist's ideas over another's?

Staying on-topic on a science-discussion (not debate) website is a must, not a want. Adherence to the Comments Policy is also not optional.

    @ KR Not an expert an the Arctic, but my read on Chylek2009 is this: The Arctic temps are heavily influenced by the AMO, which makes sense. The problem is, and perhaps Robert Way could provide some insight on this, that (as currently defined), the AMO is not properly detrended for the post-1975 warming. The detrending performed is linear, but the warming itself since 1975 is non-linear. Tamino made that observation here, that (under the linearly detrended AMO definition, the post-1975 increase reflected in the AMO is because of global warming. It is the residue of global warming. That being said, Chylek 2009 only says the rates of Arctic Amplification were greater in the earlier time frame than the later. It does not say that the earlier was warmer. Tamino also removes the cyclical exogenous factors from the temperature records to show this: My two cents. HTH. The Yooper

    33, Adam, I love that graph, and that paper!!!! I love them!!! The caption for the graph, in particular referencing the lower graph where things match so very nicely between cosmic rays and tropospheric temperatures, says this:
    The lower panel shows the match achieved by removing El Niño, the North Atlantic Oscillation, volcanic aerosols, and also a linear trend (0.14 ± 0.4 K/Decade).
    This is great. Remove El Niño. Check! Remove North Atlantic Oscillation. Check! Remove volcanic aerosols. Check! Remove global warming. Check! Wait! Remove global warming? Yes. If you take global warming out of the picture, the match is perfect. They have basically proven for us that cosmic rays have nothing whatsoever to do with current warming. Does it have an influence on natural short term variations? Apparently (although I'm not so sure that these are people I trust, but since I could care less about short term variations, it doesn't matter much). But does it have any influence on global climate? Is there any attribution whatsoever for the current warming trend due to cosmic rays? They have proven that this answer is "no." [I also despise anyone who puts out a PDF of a paper and tries to make it look like a peer reviewed journal article, which this clearly is not. For shame.]

    Adam - Thanks for repeating the Chlylek link. Looking at their paper, it's quite evident that Arctic (and for that matter Greenland) temperatures follow the global temperature trends. Their statement that Arctic amplification is insufficient to explain the magnitude of such trends is a bit more iffy, however, bordering on odd. I would be interested in the Arctic expert's opinions on this. The AMO data is also quite interesting; given that the AMO appears to also track the temperature anomaly record, however, I would consider this a possible correlation to temperature (and changing wind patterns) as a first cause - otherwise you have to argue that the AMO is affecting global temperatures, including the Southern Hemisphere, which I quite frankly would have to see some strong evidence (and a plausible mechanism) for before accepting. Have you at least dropped the strawman argument about CO2 being the only driver of climate?
  45. There is no consensus
    Bruce Frykman - The major problems that I see with your posts are: - Ad Hominem accusations of distortion against the majority of climate scientists with no evidence for same. - Posting ideology rather than facts. - Major, major tendencies to run off-topic. Do you have any science to present? Evidence? This site is set up to discuss science, after all, not politics. If you don't, then it's your opinions versus assembled facts. Quite frankly, in my view, your opinions aren't holding up very well...
  46. Monckton Myth #16: Bizarro World Sea Level
    adrian #24 - try in the ballpark of 1 meter sea level rise by 2100. Just because the IPCC AR4 didn't include melting land ice doesn't mean it won't melt - in fact it already is.
  47. The e-mail 'scandal' travesty in misquoting Trenberth on
    @Albatross #84 Don't worry. I understand what you say. I see this kind of characters like they being magicians that are meaning they really vanished the coin because they have powers and idiotic masses prone to believe them. But the answer is not speaking about the impossibility of violating the laws of Thermodynamics, but explaining the public what blind spot the magicians exploited, and most of all, where are the hidden coins.
  48. It warmed just as fast in 1860-1880 and 1910-1940
    Anyway, this is getting pretty tiring. I'm leaving now. I'm going out tomorrow, so I probably won't be able to comment again until tomorrow evening. So long.
  49. There is no consensus
    Bruce@343 "Is this really a debate forum?" No. It is a forum for the presentation and discussion of scientific evidence.
  50. It warmed just as fast in 1860-1880 and 1910-1940
    Adam#22: "the 2003 and 2010 spikes were just one year events, which quickly went back to normal straight after. Could you please explain how it could have been anthropogenic co2, which caused those two spikes," No one said those one year events were caused by CO2. "The temperature in Greenland for 1920-1940 didn't have many outlier temp anomalies, it stayed at roughly the same trend over those few decades. " That's just not true. There is in fact a 1.2 degree jump in 1919 (I just plotted the Polyakov data). If that's in error, your rapid 1930s warming is a thing of the past. Wouldn't a real skeptic question an entire conclusion that rests on the validity of a single data point?
