Comments 97851 to 97900:

  1. It's freaking cold!
    Thanks for linking to the paper JMurphy. I just read it "Our discovery of an ecologically sudden demise and back-stepping signature in reef-crest deposits from the Yucatan is therefore compelling evidence for a sea-level jump with a similar rise rate during the late stages of the last interglacial. This jump implies that an episode of ice-sheet instability, characterized by rapid ice loss, occurred late during an interglaciation that was warmer than present." Wanted to see that video, Michael. Perhaps you could just post a direct link to it? I don't know. Watched that video Truevoice and I don't see how your and the article's conclusions match the evidence.
  2. The Climate Show #5: Green roofs and Brisbane floods
    Camburn, I think you underestimate the satellite-derived precipitation data. Please read more about the SSM/I data and there validation. I'm afraid to tell you that rain gauge and radar (especially C-band) data are also fraught with problems, they are not the panacea that some think them to be-- I have worked with both platforms and can attest to the fact that they have issues. Yet, I do not dismiss the research done using them simply b/c they provide inconvenient or uncomfortable results. Regardless, I pretty coherent, robust and substantive picture is beginning to emerge with time using data from multiple, independent precipitation observation platforms. Further, the observations suggest that the models are likely underestimating the increase in precipitation intensity (see the papers by Zhang et al. and Wentz et al above). Please apply your "skepticism" properly and not uni-directionally.
  3. It's freaking cold!
    Sorry my link has been deleted. Apparently Accuweather does not like it when they are transparently stupid. Today Bastardi is showing a temperature chart of January over the USA and claiming that it shows the globe has cooled.
  4. It's freaking cold!
    Let's also not forget Bastardi's inability to recognize a temperature anomaly map early last year. Typing from an iPad, so I'll have to link the hard way: http://climateprogress.org/2010/03/24/accuweather-joe-bastardi-anti-science-meteorologist-sea-ice/
  5. A Case Study in Climate Science Integrity
    Tom (RE: 33), "RW1 @29, you seem to alleging that because a seasonal cycle which results in a 200+ w/m^2 variation in insolation at mid latitudes causes an appreciable change in temperature within a year, that therefore an approximately 4 w/m^2 forcing will heat the ocean to the equilibrium temperatue in less than a year." Not quite. I'm simply saying that the amount of ocean temperature change that occurs every year in each hemisphere would be impossible if the equilibrium response time to increases in radiative forcing were on the scale of years or decades. "You allege this despite the fact that the lower the difference between net energy in and out, the lower the rate of heating;" We are talking about equilibrium response time - not rates of heating. Unless you want to argue that smaller increases in radiative forcing take longer to reach equilibrium than larger ones? If so, under what law of thermodynamics would this occur? "and you allege this despite the fact that even for seasonal variations the ocean never reach the equilibrium temperatures associated with the maximum and minimum of insolation." I'm well aware the seasonal variations of the oceans never reach equilibrium; however, the rate and amount of heating that occurs is way too fast to be years or decades.
    Moderator Response: [muoncounter] Further discussion of ocean heating must go to the appropriate thread. Further discussion of laws of thermodynamics must to to that thread.
  6. It's freaking cold!
    Check out this video of Joe Bastardi to see how "accurate" he is. In it he criticizes the NSIDC for inaccurate graphs of the sea ice, compared to several other graphs. The actual issue is that Bastardi cannot read the graphs and is completely wrong. Bastardi also calls the ice area "close to average" when in fact it is close to the record lowest level. The NSIDC corrected him and he apologized. Anyone who cites Bastardi as a reliable source needs to learn how to read graphs.
  7. Monckton Myth #6: Global Sea Ice
    Eric the Sceptic #5 Your graphs shows a decline in sea ice from around 1850 to the present, represented as a simple dashed straight line fit to the curve. A temperature or CO2 increase over the same period would show the same straight line fit as a rising trend. So what are you being sceptical about? Your data doesnt go back quite far enough, but looking at the trend more closely year by year, your data shows a reasonable fit between declining sea ice which seems to start on average in roughly 1910 and rising temperaturs which also started significantly in around 1910. Ice core data shows CO2 rising significantly from around 1880. Solar activity was also strong around 1900 to mid century and likely an influence. So I cant see why you being sceptical or what your point is.
  8. It's freaking cold!
    Tom Loeber, as already noted, your link (and the actual paper) does not back-up your interpretation. As Sphaerica writes, the melting mentioned in the paper is not stated as causing a rapid cooling, therefore your statement that "recent evidence that melting of the caps immediately preceeded major swings of the climate into major ice age conditions is another thing suggesting that warming leads to cooling" is not true. Not only is the "evidence" not recent (the paper being nearly two years old), it merely shows that ice-sheets melt when temperatures rise, leading to a rise in sea-level. And you don't need to read the paper to know that glaciations follow inter-glacials at regular intervals.
  9. It's freaking cold!
    The Eemian interglacial period began about 130K ago and ended 114K ago. 121K is almost dead smack in the middle of that. The article was about sea level rise. If you go find the paper, I'm sure that you'll find it was about sea level rise. You are choosing to infer some correlation between ice melt, sea level rise and the onset of a glacial period. No such correlation is stated by either the article or the study in question, so it fails to support your position that the earth is going to start cooling.
  10. It's freaking cold!
    Sphaerica, thank you for at least partially admitting your error. I do wonder though at the idea that 121,000 years ago was " seven thousand years before the earth had descended into the next glacial period." Without referencing, that appears to contradict what I recall the quite well established record suggests.
  11. Monckton Myth #6: Global Sea Ice
    Jonathan @ 10: The graph I linked in number 1 shows the ice extent. The graph that you see first on Cyrosphere Today shows sea ice area. The extent is the amount of sea covered by more that 15% ice. The area is the total amount of ice only, so it is smaller. I think you are comparing the 2010 ice area to the ice extent in 1980. The NSIDC likes to graph sea ice extent (IJIS also graphs extent). Cryosphere Today likes to graph area. The two data sets are very similar in trends, but you have to be careful not to directly compare them.
  12. It's freaking cold!
    Tom, 98. In looking back into the numbers (121K ago), they look like they were referring to what amounts to the last half of the interglacial as the "terminal phase." That said, this fell at the midpoint (the high point) of the interglacial. [I was confused because "terminal phase" is a term commonly used for the abrupt and extreme warming which marks the very beginning of an interglacial, but the end of a glacial period.] But the period discussed in the article was still seven thousand years before the earth had descended into the next glacial period. The melt was not the cause of the coming glacial, nor was it even a sign of an impending descent into a glacial period. It merely came at the point of peak temperatures, which also marks the beginning of the decline (which is triggered by changes in the earth's orbit, axial tilt, etc.), so the person quoted described it as a terminal period. You're interpretation of what was said is still incorrect. Melting Arctic ice is neither a cause nor a sign of impending cooling.
  13. It's freaking cold!
    Tom, Sphaerica knows exaxtly what he's talking about, your own comprehension is what is in question. An interglacial is a period during an ice age in which ice does not dominate the planet. This means the interglacial itself is a "terminal phase" of glacial dominance. You don't understand ice ages, you don't understand the terminology and you seem to be unaware of the difference between a newspaper and a scientific publication. Grab a copy of "The Physics of Glaciers", read it, then come back and we can discuss your difficulties.
    Moderator Response: [muoncounter] This thread is about cold weather as an aspect of or objection to global warming. Further discussion of ice ages belongs on We're heading into an ice age.
  14. It's freaking cold!
    Tom, So you didn't read it. Good to know. You still haven't responded to the fact at hand: you linked to an article which you claimed provided evidence of polar ice melt being linked to rapid cooling, when in actuality the article discussed melting due to warming during the previous interglacial. Your own link stands in complete contradiction to your assertion. At this point I can no longer tell if you simply don't understand the science, or are being deliberately obtuse.
  15. It's freaking cold!
    Sphaerica "during the terminal phase of the last interglacial period." You interpret that to not mean what it says?
  16. It's freaking cold!
    The article is reporting of a scientific publication. Even the publication itself is an article. "Did you even bother to read it? Trueofvoice, could you lay off of the ad hominem please? I don't think it adds to your credibility.
    Moderator Response: [Daniel Bailey] A simple question does not constitute an ad hominem. If you think it does, you should perhaps look the phrase up.
  17. It's freaking cold!
    Tom, 94, You have completely misunderstood this quote from that article, and the context of the article.
    "We constrain this jump to have occurred 121,000 years ago and conclude it supports an episode of ice-sheet instability during the terminal phase of the last interglacial period."
    "The terminal phase" is the period immediately following a glacial period, i.e. a period where temperatures suddenly and abruptly warm, taking the planet out of (not into) a glacial period. "Terminal" refers to the end of the glacial period, not the end of the interglacial period. The article is discussing the rapid and large sea level changes which can occur during those termination events. That is completely the opposite of your interpretation:
    "I think the recent evidence that melting of the caps immediately preceeded major swings of the climate into major ice age conditions is another thing suggesting that warming leads to cooling."
  18. It's freaking cold!
    Tom, Your link is to a newspaper article, not a scientific publication. More importantly, the article is regarding rapid sea level rise during the previous interglacial. It says nothing about melting ice caps initiating an ice age. Did you even bother to read it?
  19. It's freaking cold!
    Hi JMurphy. "We constrain this jump to have occurred 121,000 years ago and conclude it supports an episode of ice-sheet instability during the terminal phase of the last interglacial period."
  20. Monckton Myth #6: Global Sea Ice
    MikeCoombes @13, here is the graph of global sea ice area Tamino reproduces in the update linked in the main article: By eyeballing the graph, I estimate the annual average sea ice area is around 19-20 million square kilometers. The sea ice area anomaly over the last few years has averaged (by eyeball) around -1 million square kilometers, which represents a 5% decline. The sea ice extent anomaly seems to be of similar magnitude, ie, around a 5% decline. Given that, are you inclined to agree with Monckton, or James Wright and Tamino?
  21. It's freaking cold!
    Tom, 91,
    all of that last post of yours appears to be an attempt to deride my character
    Not your character, I am deriding the quality of the information you post and the debate tactics that you use to present it.
    ...you wont look at Bastardi's presentation of satellite data...
    Something written, yes. Video blogs, no. If you make a claim, and someone requests a cite, you are obliged to comply or else your statement must be dismissed as unsupported by evidence. So far, several people have asked you for cites, and you have not complied once.
    ...you claim to know his stance exactly.
    I never made any such claim. He is a well known AGW denier. I've seen any number of false and misleading statements by him. I have never seen a truthful or well reasoned statement by him. There are any number of people who have achieved the status of untrustworthy in the subject of climate science, and for me he's one of them. I will not waste my time looking at his claims until he succeeds in publishing a paper in a peer reviewed journal. Until then, it's just another guy coming up with crazy theories based on an incomplete and incoherent background in science. But so far, what you've presented is that you like his statements, and to you they seem true, so everyone else should accept that. My position is that you have presented only (1) his claims and (2) false statements, or (3) true statements which either fail to actually support his position or else simply confuse the reader. You're going to have to do better than this if you want to succeed in making a valid point.
  22. It's freaking cold!
    Tom, "So, cooling of the stratosphere and the mesosphere proves global warming". Proofs occur in mathematics, not science. This, however is clearly not the least of your confusion. 1) CO2 gets pulled out of the air by ocean aborption and rock weathering. Biomass doesn't have the capacity to draw down sufficient CO2 to cause an ice age. 2) more moisture in the air means more heat, because water vapor is a greenhouse gas. 3) More snow in Antarctica won't reflect more sunlight into space because the whole freakin' thing is already white! 4) Your repeated references to scientists and the goverment "spinning" and "spending" in favor of Milankovitch Cycles is really, really weak. The fact that you resort to making political statements ruins any credibility you may have had. 5). If Joe Bastardi has a serious analysis indicating major negative feedbacks, let him publish them in a peer-reviewed journal. His videos are assertions, nothing more. 6) "Do you agree that I don't agree with AGW"? What does that even mean?
  23. It's freaking cold!
    Sphaerica, all of that last post of yours appears to be an attempt to deride my character. You suggest that you wont look at Bastardi's presentation of satellite data and yet you claim to know his stance exactly.
  24. It's freaking cold!
    Tom Loeber wrote : "I think the recent evidence that melting of the caps immediately preceeded major swings of the climate into major ice age conditions is another thing suggesting that warming leads to cooling." I'd be interested in reading about that. Got any references/links ?
  25. It's freaking cold!
    Tom Loeber, #87,
    ...the data is in his video blogs that prove you mistaken a number of times in your characterization of Bastardi.
    I think not. As requested, please provide a cite rather than a vague reference to statements buried somewhere in his video blogs (which I promise you I will never waste my time watching).
    But does it prove that the climate will only continue linearly to warm?
    Strawman distraction. Other evidence proves warming. My statement merely proves that your reference to the mesosphere cooling as evidence of a coming cooling period is silly.
    I understand Italy recorded...
    Yes, yes, yes, and it still snows in the winter etc. etc. etc. This is all covered elsewhere and is evidence of and an argument for nothing. Global mean temperatures are rising. Anecdotal evidence of places and times with low temperatures are meaningless.
    I am attempting to look at the evidence myself ...
    No, you're not, your spreading a great amount of disinformation under the guise of scientific statements and (according to you) reputable sources. Little of what you've posted is true, but it looks just erudite enough to confuse the unwary.
    ...you are deluded.
    But at least I'm educated, I understand everything you wrote and every place that it wanders from merely false into laughably silly. My position, whether or not you think it is a delusion, is based on reason, science, observation, and understanding. You, and anyone who is reading your posts and nodding in agreement, would be well advised to hit the books. Reaching a false conclusion based on the best possible evidence and effort is one thing. Reaching a false conclusion because one refuses to learn, study, or reasonably try, or because one has a predetermined conclusion which they are desparate to support... that's self-delusion.
  26. It's freaking cold!
    Tom Loeber, #85, Whoa, that's quite a great example of gish-gallop. The number of false statements, misinterpretations, innuendos, leaps of logic and unjustified conclusions, not to mention the subtle back-handed pleas to try to make yourself seem reasonable ("Hmmm, I see that the concept of it being natural is considered contemptible by some") are too numerous to take the time (and space!) to debunk. It's quite a collection. Your understanding of ice ages, glacial ice formation and the like is extremely weak. You need to study that a lot more before making your proclamations. When you get to this:
    I think you are just continuing with the misinformation.
    Wow. Just wow.
  27. It's freaking cold!
    Sphaerica, the data is in his video blogs that prove you mistaken a number of times in your characterization of Bastardi. So, cooling of the stratosphere and the mesosphere proves global warming. I don't doubt it. But does it prove that the climate will only continue linearly to warm? I understand Italy recorded an all time record low something like yesterday. I think Florida just recorded record lows for at least the lower half of the state. I'm not trusting any one, actually. I am attempting to look at the evidence myself and formulate an on-going subject to change opinion. Again, I suggest if you think that you KNOW exactly what is going to happen, whether or not it is your own opinion or taking the opinion of others, you are deluded.
  28. It's freaking cold!
    Tom Loeber, Um... I'm not sure how you can present Joe Bastardi as in any way reasonable. He is very much the opposite. It looks very much like you're simply trying to build him up as reasonable and scientific to get people to keep reading, only to reach his personal punchline, which is that AGW is a hoax.
    I know some folks find anything that is alarming should be met with much skepticism.
    That was your tag line to make it seem like you're on the AGW side of the fence.
    Bastardi seems to base his understanding only on quite substantially verified evidence.
    Um, sorry, no, he bases it on the same, old, tired denial arguments that this site exists to debunk.
    I learned he doesn't appear to totally discount the idea that our influences on the planet might somehow be involved.
    Um, sorry, no, he is in complete denial about AGW, and there's no way of arguing otherwise (if you honestly think you can prove otherwise, please provide a cite).
    ...he states the need to go green or carbon neutral is more necessary to avoid greater destruction by cooling than by warming...
    Funny how quickly we flipped from AGW to AGC, while making him seem like a reasonable chap because you claim he wants to "go green" and "carbon neutral"... again, a cite to this would be nice.
    He appears to be ... valuing honesty and openness as well as have an understanding of basic logic and sound theorizing
    No, no, and no. He uses the same dishonest denial positions that are used elsewhere. Casting him as valuing honesty is itself dishonest.
    ...that seems to fit in with Bastardi's observations and predictions, on-going global cooling for the foreseeable future...
    And this is where you start running wildly, totally off the rails with jibberish.
    There is a recent finding that the mesosphere within the last couple of months was measured as having reached the lowest temperature ever recorded.
    This is a beauty. This actually is evidence of GHG induced global warming. The mesosphere is a vast area above the stratosphere. GHG theory predicts that CO2 will warm the troposphere and cool the stratosphere. Observations support that this is in fact what is happening. The mesosphere is only warmed by the stratosphere, so if the mesosphere is cooling, it is further evidence that the stratosphere is cooling, which is further evidence in support that greenhouse gases are warming the planet. Here's a tip: Don't get your climate science from meteorologists, whether they be named Bastardi or Watts. Trust climate scientists, not snake oil salesmen.
  29. Monckton Myth #6: Global Sea Ice
    The sentence at the end of third paragraph (see below in italics) does not provide the reader with the information to agree or disagree. You would need to provide the total area or state what percentage decline that is. If it is a 0.10% decrease most would agree with Monckton; if it 10% most would agree with you. The net result is a statistically significant global decrease of more than a million km2 – would you agree with Monckton that this is “virtually no change”? Keep up the good work!
  30. It's freaking cold!
    Hmmm, I see that the concept of it being natural is considered contemptible by some. I think the evidence that remineralizing soils greatly increases the amount of carbon dioxide sequestering biomass is probably a part of the cycle. I wonder as to the use of the term "natural" and suppose it only holds to something that is not man-made though I think we can argue that humans are a natural phenomenon and their actions on the planet consequentially natural but, seeing ourselves as somehow separate from the equation, isn't that what the deniers are claiming? I think the recent evidence that melting of the caps immediately preceeded major swings of the climate into major ice age conditions is another thing suggesting that warming leads to cooling. Think about it. What provides the energy to put great amounts of the planet's water onto the land masses in mile thick glaciers? Are ice ages where there is more biomass tying up carbon dioxide or might they be the result of more green house gases in the atmosphere, more moisture driven into the atmosphere that leads to more turbulence driving moisture so high and more methane release as to create those noctilucents? I think the Milankovitch cycles are less damning of humanity's actions and why there is evidence that money was spent to spin the evidence in their favor, absolving human activities of any influence. How about that hit piece on noctilucents? Should I go dig up the pdf linked to earlier by another so you could take a closer look at it? i suppose you are aware that much money has been spent to provide research favorable to discounting humanity's influence on climate and weather. I think I could dig up the references to the analysies that suggest millions of dollars have been spent meant to keep us nonchalant and discounting of AGCC, read that as Anthropogenic Global Climate Change. Trueofvoice, I was with you until you presented not understanding what Mr. Bastardi published, with reference to possible cause but at the same time he stated he did not buy into the sun's output lessening himself as being the cause. He did offer that though counter to your claim. As far as referring to Riccardo and Daniel arguing from sound scientific principles, I think you are just continuing with the misinformation. Do you agree that I don't agree with AGW? I mean, it is quite obvious that was not a scientific conjecture of any plausibility and just a simplistic straw-man argument approach. I don't know. It's too bad only those who seem to cater to the idea that there is more than just theory seem to have the temerity to post here. I do hold that us humans as relatively recent biological systems are quite naive and we tend to lend credibility to our organization experiments beyond any sense or reason even to the extent of considering this message board as beyond error, beyond censoring or bias. I know that is not truth though many have countered that it is not so.
  31. Monckton Myth #6: Global Sea Ice
    My drinking buddy, Morde Lockton, insists that it is all cosmic rays. He read that scientists in India studied and measured increased Galactic Cosmic Rays. http://www.hindustantimes.com/News-Feed/newdelhi/Ramesh-backed-paper-questions-another-IPCC-claim/Article1-652754.aspx So it must be.
    Moderator Response: [muoncounter] They measure GCRs in other places on earth as well, so maybe they are secretly a Martian genetic engineering weapon (see HG Wells). However, they are off-topic for this thread. Go to Its cosmic rays for further discussion of fiction vs. non-fiction.
  32. It's freaking cold!
    Tom, Actually it would be great if you would elaborate. Exactly how will global warming reverse itself into a cooling trend? What negative feedbacks are powerful enough to accomplish this? If Mr. Bastardi is aware of such a mechanism, why hasn't he published his findings? Daniel and Riccardo are arguing from sound scientific principles, while your working assertion that climatologists can't see past averages and surface temperatures is utterly false. You're going to have to do better than that.
  33. It's freaking cold!
    Tom Loeber it's really hard for me to understand how you can think I don't like observing the data. It's also hard to understand how you can think he proved anything wrong when he just threw a few insignificant facts, claiming they're conclusive. As for the "grand over-all reaching theory" I don't understant what you're referring to, I don't know any. It may just reflect your perception of the knowledge in climate science accumulated for over two centuries.
  34. Monckton Myth #6: Global Sea Ice
    Ron #6 - we'll be discussing Flanner et al. 2011 in an upcoming post, probably early next week. I'll also touch on it in Monckton Myth #7 (regarding snow cover), which is also in the works.
  35. Monckton Myth #1: Cooling oceans
    #67: "7-8 years of Argo is hardly a short period" Seven-eight years is a short period in any climate context. The length of the data record doesn't change that.
  36. Monckton Myth #6: Global Sea Ice
    What is visually most striking in this post is the fact that the summer sea ice extent in 1980 is the same as the winter extent in 2010.
  37. It's freaking cold!
    #81: "staying open with questions as to the possibility of AGW leading to AGC is so much of a no-no" An idea is only a 'no-no' if you can't support it with some credible evidence. Do you have any for 'AGW leads to AGC'? Or is that a natural cycle?
  38. The Climate Show #5: Green roofs and Brisbane floods
    #8: "Note the last sentence of the abstract." The Huntington paper, with its "should not be taken as evidence that further warming will not lead to such changes in the future" was accepted for publication in July 2005. Ironic that a mere 6 weeks later, Katrina arrived and the remainder of the 2005 Atlantic tropical storm season was one of the worst ever. Pretty good prediction of the future after all.
  39. Monckton Myth #6: Global Sea Ice
    Camburn @ 8... But that phase is well understood in terms of obliquity. The north pole was pointing more directly at the sun some 6-8000 years ago. On the other hand we are currently looking at ice free summers in the arctic in the coming decade or two, something we have NOT seen on this planet for a much longer period of time.
  40. It's freaking cold!
    Yooper, I totally agree with everything you state there and I too am a believer that we have AGW. I guess though staying open with questions as to the possibility of AGW leading to AGC is so much of a no-no that straw-men arguments are seen as worth while. Ah, thank you Riccardo. i see you maybe don't like analogies nor observing the data but would rather there be some kind of grand over-all reaching theory presented as knowledge? You know that guy? Care to elaborate? I tend to like that he seems to not hold certainty but is only looking at confirmable data and what we know from the past to conjecture about the future. The fact that he suggests great alarm at being proved wrong should show that he is not suggesting he knows what the grand scheme is. I wonder as to your wherewithal if the major criticism you have to offer is that he doesn't offer or adhere to any grand theory.
  41. Monckton Myth #6: Global Sea Ice
    The ice declined a lot during the early Holocene as well. http://gizmo.geotop.uqam.ca/rochonA/Fisher_et_al_Eos_2006.pdf
  42. It's freaking cold!
    Re: Tom Loeber (78) The Big Picture you are missing is that the part of the atmosphere where humans happen to live is the part warming the most. And that the cooling of the stratosphere and mesosphere is an integral part of that warming signal so characteristic of rising levels of CO2. Recent events, both in terms of temperature and precipitation, are being shown to have a causal relationship consistent with AGW. To say that we cannot have a level of understanding deeper than that you've demonstrated is simply incoherent. The Yooper
  43. It's freaking cold!
    Tom Loeber "He appears to be relatively free thinking" a little too free, in my opinion; free from the influences of the physics of climate, in first place. He goes on and on with analogies and eye-balling correlations while I was waiting for some insight on the mechanisms leading to his predictions. I wasted my time. Not a surprise, though, I know this guy. "Maybe though we are missing the big picture if we only consider surface temperatures and averages." I agree that if one considers only surface temperatures and averages is missing the big picture. I wonder who's doing this. This post was written exactly to counter such kind of over-simplifications. I think we may agree on the simple fact that the globally average surface temperature is the end result of much more complex processes which determines it. No surprise that it took 1000 pages and a lot of scientists time to just summarize in the IPCC AR4 the most recent science. But this end result is what has a direct impact on our lives, so I'll keep watching the surface temperature trend.
  44. Monckton Myth #6: Global Sea Ice
    Eric, I have not seen data with error bars on them. Even if the error bars are large, it still indicates a substantial decrease in the ice area before 1980. The scientists at the NSIDC would know what the error is. The flatness, especially in the Antarctic, is certainly due to lack of accurate data. On the other hand, that does not mean that there is no data. You have to work with what data you have. And the data after about 1940 is more detailed. Your ice edge data is consistent with the Arctic data from Cryosphere Today. The ice declined a lot from 1900 to 1980. That needs to be kept in mind when we look at the ice situation today.
  45. It's freaking cold!
    Gee, I've gone through the past couple months of these videos by the meteorologist Joe Bastardi of Accuweather.com . This latest one is alarming. I know some folks find anything that is alarming should be met with much skepticism. Bastardi seems to base his understanding only on quite substantially verified evidence. I learned he doesn't appear to totally discount the idea that our influences on the planet might somehow be involved. In one of the other recent video blogs he states the need to go green or carbon neutral is more necessary to avoid greater destruction by cooling than by warming. He appears to be relatively free thinking, coming off the top of his head and valuing honesty and openness as well as have an understanding of basic logic and sound theorizing. Boy, that hit piece on noctilucents that only used 36% of their spread in time to discount their influence appears to have done the trick to keep the alarm of their appearance and increase apparently in step with the increase of carbon dioxide on the planet from consideration. That seems to hold greater impact on the climate, basically via Earth's albedo, than sunspots. As far as I can tell, the sun is still only within one tenth of a percent of its observed output. To have first surface mirrors coat the planet in the mesosphere reflecting perhaps as much as one percent of the incoming sunlight back into space, growing in frequency and duration, that seems to fit in with Bastardi's observations and predictions, on-going global cooling for the foreseeable future. There is a recent finding that the mesosphere within the last couple of months was measured as having reached the lowest temperature ever recorded. Please. Yes there has been record heat. Maybe though we are missing the big picture if we only consider surface temperatures and averages. It is the idea that we are experiencing unpredicted anomalies in the weather AND climate that suggests interpretation of global warming as only increasing and proceeding linearly as quite non-causal. Meteorologist Joe Bastardi discusses satellite evidence of a cooling atmosphere. I don't know, really. I do think that any one who pretends to know is misleading themselves as well as others.
  46. The Climate Show #5: Green roofs and Brisbane floods
    Albatros@11: Personally, I am not comfortable with satillite data indicating rain, or its intensity. As a farmer, I watch the satillite/radar data with great interest. South America does not have a very good radar system, so one has to rely on satillites for hints of their precip pattern. Cloud temp etc will indicate that rain should be falling, and a lot of times it isn't. The satillite maps are useful in that one can see what should be happening, then find the local meteorlogical office for that potential event to see what emperical evidence of rain etc is there.
  47. The Climate Show #5: Green roofs and Brisbane floods
    Camburn, Thanks for the link. Huntington (2006, J. Hydrol.). From his conclusions: "Consistency in response among multiple variables lends observational support for theoretical arguments and GCM predictions that warming will likely result in further increases in evaporation and precipitation.The theoretical hydrologic response to a warming-induced intensification as manifested in an increasing frequency and intensity of tropical storms and floods (Knutson and Tuleya, 1999; Tuleya and Knutson, 2002; Karl and Trenberth, 2003) is not supported by the preponderance of evidence to date. Because of the long-term return intervals and stochastic nature of the occurrence of extreme events, however, it may require substantially more time before a change in frequency can be detected (Free et al., 2004). The lack of detectable trends in the frequency and intensity of tropical storms during the 20th century should not be taken as evidence that further warming will not lead to such changes in the future, particularly as the rate of warming in the 21st century is expected to be several times greater than in the 20th century (Cubasch and Meehl, 2001)." The Huntington paper is actually in closer agreement with the findings papers I cited than his abstract suggests. The paper cited referring to tropical storms and floods are quite old, from 1999-2003. The Allan et al. (2010) paper uses satellite data (which provides continuous spatial and temporal coverage) and reveals a different picture regarding tropical storms: "The SSM/I data indicate an increased frequency of the heaviest events with warming, several times larger than the expected Clausius–Clapeyron scaling and at the upper limit of the substantial range in responses in the model simulations."
  48. Monckton Myth #6: Global Sea Ice
    Don't forget the albedo. Flanner et al 2011 "We estimate mean Northern Hemisphere forcing at −4.6 to −2.2 W m−2, with a peak in May of −9.0±2.7 W m−2. We find that cyrospheric cooling declined by 0.45 W m−2 from 1979 to 2008, with nearly equal contributions from changes in land snow cover and sea ice. On the basis of these observations, we conclude that the albedo feedback from the Northern Hemisphere cryosphere falls between 0.3 and 1.1 W m−2 K−1, substantially larger than comparable estimates obtained from 18 climate models."
  49. We're heading into an ice age
    LandyJim, "Dominance" isn't a relevant term in regards to Milankovitch Cycles. MC's are forcings, meaning they initiate a change. CO2 and other greenhouse gases begin to accumulate in the atmosphere in response, which is why we call them feedbacks. Once those gases reach a certain concentration, they exert a greater influence on climate than the relatively small change initiated by the change in Earth's tilt toward the sun. Let me say this again: Milankovitch Cycles do not "dominate", they initiate.
  50. A Case Study in Climate Science Integrity
    fydijkstra @36, your objection shows a misunderstanding of the effect of thermal lag on green house warming. When the level of greenhouse gasses increase, that creates an imbalance betweeen incoming and outgoing energy at the top of the atmosphere. The balance is restored primarilly by the surface of the Earth, including the surface of the ocean, warming until the increased IR radiation from that surface compensates for the imbalance. Now suppose the ocean warms to that temperature, but then some of the heat flows to the deep ocean, cooling the surface. Well, then the surface of the ocean will no longer be warm enough to compensate for the imbalance anymore. Consequenlty the surface of the ocean will warm some more. Until the temperature required to restore the imbalance is reached, and heat transfers in the ocean are in quasi-equilibrium so that the surface does not cool again, it will keep on warming. You are wrong, by the way, about both Mann and Santer. Mann did not do anything untoward in his first papers on temperature reconstruction. He did not do it perfectly, but that was because he was the first to do it, and nobody knew what was the best technique. It was only after a few attempts were made that it became clear which were the best techniques, and what pitfalls to avoid. McKittrick has tried to take some minor and inconsequential flaws and try and blow it up into a case for fraud, and and indictment of everything that has followed in the field regardless of how disimilar the techniques used. He is a con artist who is trying to keep you preoccupied with his flashing hands so you don't see the mountain of science that demolishes his position. I'm sure Dana can redirect you to a thread which is better for discussing this topic, and Santer.
    Moderator Response: [muoncounter] There is a thread for the ocean heating/cooling discussion here. Comments re thermal inertia of the oceans should go there.
