  • The “Canonical” Varve Thickness Series « Climate Audit
    786 Alaska climatological divisions Trends of varve thickness also correlate with trends of annual temperature in Seattle and North Head Washington r 632 and 850 respectively Comparisons of trends of varve thickness with trends of annual temperature in California Oregon and Washington suggest no widespread regional correlation Trends of annual snowfall in the southern Alaska climatological division and trends of annual temperature in the southern and northern Alaska climatological divisions are reconstructed for the years 1700 1906 A D Climatic reconstructions on the basis of varve thickness in Skilak Lake utilize equations derived from the regression of series of smoothed climatological data on series of smoothed varve thickness Reconstruction of trends of mean annual cunulative snowfall in the southern Alaska climatological division suggests that snowfall during the 1700s and 1800s was much greater than that during the early and mid 1900s The periods 1770 1790 and 1890 1906 show marked decreases in the mean annual snowfall Reconstructed trends of the annual temperature of the northern and southern Alaska climatological divisions suggest that annual temperatures during the 1700s and 1800s were lower than those of the early and mid 1900s Two periods of relatively high annual temperatures coincide with the periods of low annual snowfall thus determined I have inserted r where the paper had r with an overscore not sure how to reproduce the overscore in my browser Matt So it was well known 30 years ago that snowfall confounds temperature in proglacial lake sediment varve thickness On the west coast of the US snowfall occurs when marine moisture meets cold dry arctic air This is weather more than it is climate Note that the coldest periods 1770 1790 and 1890 1906 somewhat coincide with the coldest periods in the other proglacial lakes I would surmise that the cessation of snow during these periods would be related to the weather we have right now a massive dome of frigid arctic air keeping marine systems well off the coast HaroldW Posted Dec 5 2013 at 2 51 PM Permalink Comparisons of trends of varve thickness with trends of annual temperature in California Oregon and Washington suggest no widespread regional correlation What does this say about reconstructions which estimate global or hemispherical temperature history from widely scattered proxies Even if the proxies were ideal thermometers for the meteorological vicinity they are not necessarily representative of the region Yet the reconstruction methodology posits that they are Craig Loehle Posted Dec 5 2013 at 5 21 PM Permalink Since Alaska is tied in closely to the PDO an obvious hypothesis for this site would be that precipitation snowfall could exhibit multidecadal fluctuations which could lead to spurious attribution of varve thickness to temperature since the highest correlation is to cumulative snowfall It is stunning how many times the effects of multiple factors distance of the glacier effect of snow or rainfall are simply dropped out of the models for temperature reconstruction too inconvenient I guess Kenneth Fritsch Posted Dec 5 2013 at 11 48 AM Permalink Is not this analysis merely a round about way of pointing to the flaw in the basic approach to almost all of these temperature reconstructions i e selection of proxies based on the correlation of the response to the instrumental record as it very clearly is noted in the Shi et al 2013 paper Do not these authors of temperature reconstructions realize how easy it is to obtain a low frequency correlation between an upward trending observed temperature and any other upward trending measurement and without a direct cause and effect relationship between the two variables That there is poor correlation between these proxy responses is evidently not a major concern with these authors as the stated criteria does not include that relationship The authors might attempt to wave away these concerns by noting that there are regional differences in temperatures which there well may be but as SteveM has been careful to note the discrepancies between proxy responses are over extended periods of time Unfortunately if temperatures were spatially varying in this manner over extended periods of time the uncertainty of any estimated mean regional temperature that encompasses these locations should have properly calculated confidence intervals from the floor to the ceiling I continue to attempt to rationalize the conceptual blind spot that allows these authors to continue to make this basic error in their approach to temperature reconstructions Perhaps part of it is that in their hurry to confirm their prior beliefs that we are in an unprecedented warming they see a correlation in some proxy responses in the same upward direction as temperature and proceed to stop thinking and start publishing Steve the older specialist literature on varves shows very clear understanding that varve thickness is not linearly and homogeneously related to current temperature but seem to be ignored in the articles proposing these various temperature reconstructions from varves tty Posted Dec 5 2013 at 4 38 PM Permalink Well that was supposed to be fixed by the shiny new methodology used by Gergis Karoly Neukom Filter out the low frequency signal and select proxies by using the high frequency signal only And we know how that worked out Kenneth Fritsch Posted Dec 5 2013 at 5 39 PM Permalink Well that was supposed to be fixed by the shiny new methodology used by Gergis Karoly Neukom Filter out the low frequency signal and select proxies by using the high frequency signal only And we know how that worked out It can easily be shown that two series with very good correlation higher frequency correlation can have very different trends low frequency correlation Ideally one would want a proxy response that shows both good high and low frequency correlations with the observed temperature like a thermometer does The conundrum is that temperature reconstructions are carried out primarily to look at low frequency phenomena trends which would point to finding temperature responses of proxies to temperature trends The problem there is that finding a spurious low frequency correlation between two trending variables is not difficult at all and particularly when you are selecting proxies I believe it is the dendroclimatologist Rob Wilson who has always reminded us of the consistency of tree rings to record prominent historical volcanic events i e a potential proxy getting a high frequency response correct The problem remains that those responses even in close proximity do not have nearly the same magnitude in response and it is that near same magnitude in a proxy response that would be required to properly proxy a temperature trend Steve McIntyre Posted Dec 5 2013 at 6 29 PM Permalink E M Leonard studied varve chronology at Hector Lake ALberta and observed that high sedimentation rates occurred during periods of moraine deposition ice maximums or during rapid recession this certainly seems consistent with the Hvitarvatn data A comparison of sedimentation rate records with recent regional glacial history indicates that high sedimentation rates of one to a few decades duration occur either during and immediately following periods of moraine deposition ie maximum ice stands or during periods of rapid ice recession Comparison of sedimentary records with somewhat longer term glacial and vegetation records indicates that sedimentation rate variations of several centuries duration closely parallel changes in upvalley ice extent Over this time scale high sedimentation rates occur during periods of relatively increased ice extent low rates during periods of reduced ice extent Within this general pattern however sedimentation rates may remain very high for nearly a century following maximum ice stands due to the exposure of unstable glaciogenic deposits to fluvial reworking during ice recession The temperature reconstruction jockeys seem to have lost contact with previous scientific knowledge about varves A number of the early temperature reconstructions using varves were from Raymond Bradley s students cbb Posted Dec 5 2013 at 8 11 PM Permalink this is off topic but Dr Leonard was a professor of mine in college He had a comic on his office door that depicted some arctic explorers looking at their dog sled All of the harnesses were empty and laying on the ground The caption was Well that s it We ve eaten the last of the geologists This was 30 years ago Seems like things haven t changed that much Matt Skaggs Posted Dec 6 2013 at 9 53 AM Permalink So the proxy actually has a U shaped response to ice extent This reminds of the work trying to compensate for age in tree rings which is also U shaped except the U is inverted Somebody was it Craig Loehle showed that with a U shaped response to an independent variable buried in the data the correlation to the variable of interest was always going to be indeterminate no matter how fancy your math Jim Bouldin s excellent series of blog posts on treemometry using synthetic data supported similar conclusions Since ice extent at any given time correlates poorly to temperature at that same time the same limitations seem to apply Geoff Sherrington Posted Dec 5 2013 at 6 02 PM Permalink Kenneth Are you saying that much of what we see is noise That s how it looks to me I agree with Steve s comments about using simple algebra as an aid to rejection of low quality data and I agree as would most of us I guess that the desirable path of data evaluation is from high quality down But then my experience might be atypical because in mineral exploration we were most interested in the fine structure of anomalous values whereas the dominant trend in climate work is to reject or smooth them Rejection of the anomaly in its broad definition not the climate one is possibly approaching the data from the wrong end david eisenstadt Posted Dec 5 2013 at 8 55 PM Permalink if you view unexplained variance as noise its easy to go down that road Instead of looking at the data available and thinking that we don t really know how to explain what we all can see we smooth away anything we think is noise The urge to draw conclusions from momentary glimpses at the underlying physics must be strong indeed unless its the late 20th century in that case the variance isnt noise its signal give me a break Kenneth Fritsch Posted Dec 6 2013 at 3 29 PM Permalink Are you saying that much of what we see is noise Those doing the reconstructions admit to that Unfortunately their approach cannot extract a signal because selection of proxies after the fact does not allow for subtracting out noise assuming that the noise is random There may well be valid temperature proxies out there but those doing the reconstructions are so wrongheaded in approach and unwilling to do the preliminary work that finding and differentiating those proxies from the invalid ones will not be an easy task I suspect the field you worked in was driven by profit and loss and involved science that was harder than that used in constructing temperature proxies You had the opportunity to conclusively test the validity of your methods and without waiting years for out of sample test results And profit and loss are good motivators for getting it right or at least better DocMartyn Posted Dec 5 2013 at 8 17 PM Permalink Steve you stated that the older specialist literature on varves shows very clear understanding that varve thickness is not linearly and homogeneously related to current temperature but seem to be ignored in the articles proposing these various temperature reconstructions from varves When did the transition between it being generally believed that varves were poor temperature proxies to being generally accepted that they were a valid means of determining regional temperature Steve McIntyre Posted Dec 5 2013 at 9 56 PM Permalink When did the transition between it being generally believed that varves were poor temperature proxies to being generally accepted that they were a valid means of determining regional temperature Interesting question that I ve been wondering about It looks like Raymond Bradley and his students had a large hand in it Lamoureux and Bradley 1996 did a temperature reconstruction for Lake C2 on Ellesmere Island They considered the possibility of inhomogeneity but set it aside Once a couple of reconstructions were in print they seem to have been relied on as authority without the contradicting literature being cited Their introduction into multiproxy studies seems to be mostly due to Kaufman et al 2009 I don t think that any of the TAR multiproxy reconstructions including MBH used any Bradley Hughes and Diaz 2003 used a couple of varve series Murray Lake and one other Kaufman used all of the varve series that are now canonical Following Kaufman they became widely used in the various Ljungqvist studies PAGES2K Shi However the repertoire of varve thickness series becomes fairly stereotyped Skiphil Posted Dec 5 2013 at 10 24 PM Permalink In my ongoing naïveté I would expect a broad series of major rigorous calibration and validation studies of diverse locales and conditions before any scientist would even begin to treat varves as reliable temperature proxies What kind of scientific field treats casual guesswork as confirmed scientific results Steve McIntyre Posted Dec 6 2013 at 12 00 PM Permalink Looking more closely Overpeck et al 1997 used six lake series including C2 and Donard jim2 Posted Dec 5 2013 at 8 22 PM Permalink After reading the varve posts my concept of their validity as a temperature proxy has become consdierably muddier Yancey Ward Posted Dec 6 2013 at 11 17 AM Permalink LOL j ferguson Posted Dec 8 2013 at 7 20 AM Permalink Bottom Feeders kim Posted Dec 6 2013 at 12 19 AM Permalink So 1 Find paleo series which are proxy to multiple physical phenomena among which conceivably temperature 2 Data mine for a hockey stick from any of the phenomena 3 Claim temperature as THE phenomena causing the hockey stick Next week we ll cover climate science communications Read up Skiphil Posted Dec 6 2013 at 12 49 AM Permalink aahhhh Kim surely there is a more sympathetic way to describe such sophisticated rigorous and bullet proof scientific procedures p s I do enjoy how you can describe the methods of current ClimateScience TM so succinctly miker613 Posted Dec 6 2013 at 9 24 AM Permalink I wonder if you have a stratospheric overview of temperature reconstructions of the past What are all the methods used what are the problems and strengths of each of them and which if any do you consider reliable Craig Loehle Posted Dec 6 2013 at 10 33 AM Permalink It is remarkable to me that there is an unwillingness to ever accept that the answer to a question such as finding a signal in noisy paleo proxies is the data are just too noisy for a valid answer or we can t verify that these are really proxies Some things are simply impossible It is not possible to drill to the Earth s core It is not possible to forecast the weather not climate 30 days out It is not possible to predict earthquakes at this time It is important to be clear about what science can and can t do Otherwise you fall for bogus claims like N Rays and healing crystals and cold fusion Someone asked if I had written about the upside down U causing indeterminacy too much nesting to reply to them Yes It is Loehle C 2009 A Mathematical Analysis of the Divergence Problem in Dendroclimatology Climatic Change 94 233 245 stevepostrel Posted Dec 6 2013 at 6 19 PM Permalink It is not possible to drill to the Earth s core Not all agree although possible and practical are not the same thing http www phschool com science science news articles going down core html Willis Eschenbach Posted Dec 6 2013 at 12 47 PM Permalink Steve McIntyre Posted Dec 5 2013 at 6 29 PM E M Leonard studied varve chronology at Hector Lake ALberta and observed that high sedimentation rates

extent Within this general pattern however sedimentation rates may remain very high for nearly a century following maximum ice stands due to the exposure of unstable glaciogenic deposits to fluvial reworking during ice recession This was the subject of my discussion with Michael Loso and the question to which he never replied I came across the reversal when I took a look at how the Iceberg Lake varve thickness compared to the local temperature There was a good fit except it was 180 out from what Loso claimed He was saying that the thick varves were a sign that it was warmer weather than usual but the data showed that thick varves were correlated with cold weather He never answered this presumably because he d have to retract a bunch of his previous assertions the details of all of this were published and discussed on CA back in 2007 the graphs are here w Geoff Sherrington Posted Dec 6 2013 at 6 46 PM Permalink Although I am a geochemist and a geologist only by contamination it can be noted that sedimentary deposition is a major topic in geology In some places it has special features that draw
