Argus at 20:50 PM on 27 February 2010Arctic icemelt is a natural cycle
Well Riccardo, who was warming it so much then, when human CO2 emissions were only a fraction (less than 1/10) of what it is now? The cows and their methane outlets? What explanation do you have in your 'data'? -
Douglas McClean at 19:24 PM on 27 February 2010Misinterpreting a retraction of rising sea level predictions
@53, Berenyi Peter wrote: "Of course, there is a steady linear rise as well due to geophysical processes (like glacial rebound), but it can hardly be more than 10 cm/century." Surely post-glacial rebound, the process by which landmasses rise after removal of the weight of glaciers which had rested upon them and caused them to sink into the mantle, causes sea levels (as measured with respect to those land masses, and ceteris paribus) to *fall* and not to rise. It is my understanding that the linear rise component you observed in these data is in fact attributable to warming (some of it an extremely delayed response to the warming experienced as we emerged from the last ice age) and not to "geophysical processes" (as distinguished from warming). -

The argument about CRU and the data is silly. CRU is not an archive center. They got the data from the original sources, who have the responsibility to archive the data. Nobody has to get the exact data set from CRU, and almost all of the data is freely available anyway. If someone takes the freely available data and gets a significantly different result than CRU, then they should submit their result and methods for publication -- and more power to them if they are right! As for my own nearly 20 year old dissertation, all of the results not published on paper are on unreadable 9-track tapes (probably long since degraded). To even read the electronic files of my dissertation itself, I would need to buy a translator program or unscramble the out-or order text. But so what? Anyone can download the original data and reanalyze it. -

gallopingcamel at 15:19 PM on 27 February, 2010 Funny! Yeah, that IOP thing is blazing around the internets today, carried far and wide because it's that rare instance where rejection is seemingly endorsed with the imprimatur of a legitimate organization. It's been dutifully deposited wherever climate science is discussed. I'm betting it'll blow up dramatically when the IOP membership notices they've been spoken for. It's a familiar narrative. -

doug_bostrom (@29), It appears that I have caused you some distress which was not my intention. Please accept my apologies. Now I will try to explain my position without using the f***d word. Yesterday the UK Institute of Physics submitted a memorandum to the British parliament that did not once use the f***d word. Even so their meaning is pretty clear: http://www.publications.parliament.uk/.../uc3902.htm I wonder why the US press is ignoring the Climategate eruptions that are taking place in the UK? Ooops! I hope you do not find the C*********e word offensive too. -

Charlie A at 14:13 PM on 27 February, 2010 Based on this analysis, you should be careful of your odds: New analysis released today has shown the global temperature rise calculated by the Met Office’s HadCRUT record is at the lower end of likely warming. The study, carried out by ECMWF (the European Centre for Medium-Range Weather Forecasts) with input from the Met Office, performs a new calculation of global temperature rise. This independent analysis is based on information from a wide range of sources. It uses all available surface temperature measurements, together with data from sources such as satellites, radiosondes, ships and buoys.The new analysis estimates the warming to be higher than that shown from HadCRUT’s more limited direct observations. This is because HadCRUT is sampling regions that have exhibited less change, on average, than the entire globe over this particular period. This provides strong evidence that recent temperature change is at least as large as estimated by HadCRUT. New evidence confirms land warming record

Charlie A at 14:13 PM on 27 February 2010Senator Inhofe's attempt to distract us from the scientific realities of global warming
@ Doug_bostrom #67 I'm merely saying that the CRU results most likely cannot be replicated. As for starting with the raw station data, it appears that the Met Office may indeed do this. I don't expect any tremendous changes in the temperature series, but then again we are looking at trends of 0.1 or 0.2 C per decade. Were I a betting man, I would give 2 to 1 odds that the overall temperature trend of the reconstructed series is lower than that of the CRU. OTOH, I would be surprised if the difference in trends were more than 0.05 C/decade. -

Sounds as though you believe the whole CRU process is quite useless. That being the case, there's no point in following their method. Instead you should obtain the raw station data and do your own analysis. Maybe you'll come up with some new insights. -

I guess you haven't read much of the harry.txt file and seen how arbitrary, opaque and non-replicable were the decisions on how series were chosen and combined. And how many known errors are in the current database. -
Charlie A at 13:18 PM on 27 February 2010Senator Inhofe's attempt to distract us from the scientific realities of global warming
The missing data at CRU is an old story. I tried to replicate some time history for islands in the Pacific and requested the original station data used for the HADCRUT3 time series for those locations. Their response was "we don't have it anymore". UEA put up this notice back in August 2009: http://www.cru.uea.ac.uk/cru/data/availability/ The key section says "Since the 1980s, we have merged the data we have received into existing series or begun new ones, so it is impossible to say if all stations within a particular country or if all of an individual record should be freely available. Data storage availability in the 1980s meant that we were not able to keep the multiple sources for some sites, only the station series after adjustment for homogeneity issues. We, therefore, do not hold the original raw data but only the value-added (i.e. quality controlled and homogenized) data." -

The raw data underlying CRU's analysis is available, the processing methods are known, if there's serious doubt about wagering large amounts of cash on predictions made on the basis of this research there's no actual obstacle to verifying the results. Compared to the money everybody's worried about the cost of doing so is infinitesimal. Moralizing about Phil Jones and CRU's lack of candidacy for being patron saints of data archiving is sort of beside the point. I'd be the last to criticize, just based on my own experience. In my real life I'm sometimes dependent on restorations done from backups being done on an hourly snapshot basis with modern equipment. When we're called to rely on those there's invariably something missing. Nobody is perfect, sadly enough. -

I would add a further point Doug. I doubt that any of the researchers collecting original climate data 30-50 years ago could have predicted the politically motivated attacks that the current crop of researchers would be subjected to. Had they predicted it, I've no doubt they'd have made a far greater effort to keep every last paper-clip & staple. -

Karl_from_Wylie at 11:59 AM on 27 February, 2010 Karl, I have a very good friend who is an active researcher and who has performed many experiments over the years. She has attempted like any good scientist to retain all data used in the course of her investigations, "just in case." Presently there are something like 500 boxes of moldering floppy disks, papers, hard disks etc. sitting in the downstairs of her house. Theoretically nearly all her work product is there, but I can almost guarantee that if she had to account for all of it there would be a shortfall of some percentage. Guess what? When a grant expires, is consumed, there's no annuity provided to fund record keeping in perpetuity. When a grant is zeroed out, entropy sets in regardless of the best efforts at preservation. If nobody is tasked specifically with archiving data it'll inexorably rot. There's nothing controversial or mystifying about this phenomenon, these artifacts are subject to the same vagaries as anything else in the physical world. CRU has managed to hang on to something like 95% of their records going back decades. That's actually a very good performance and of course is indicative of an active attempt to combat rot. Some folks would like us to imagine there's incompetence or worse at play in this matter, but in fact the CRU resides in the same physical world as the rest of us and cannot reasonably be expected to do otherwise. -

Sorry, my mistake. It is 14C, not 13C-I have a tendency to get those two mixed up-thanks for clearing that up Stuart. Still doesn't invalidate my point-namely that we *know* the most recent CO2 emissions are from fossil fuels due to the change in carbon isotope ratios in the atmosphere. Even if we couldn't identify the CO2 in this fashion, it would still leave the following question-if there was so much additional CO2 being held in natural sinks, why did CO2 levels in the troposphere never exceed 290ppm over the past 7.5 million years, in *spite* of significant changes in temperature during the interglacial periods? -

tobyjoyce at 09:48 AM on 27 February 2010Have American Thinker disproven global warming?
@garythompson, In my view, figure 5 destroys your revised statament in AT that: "Since half the wavenumbers experienced a decrease and the other half experienced an increase, the data is not compelling enough to make conclusions either way with regard to OLR for these wavenumbers associated with CO2 absorption" As Figure 5 shows,the vertical grey bans indicate regions where the differences in spectra are significantly different from zero. The legend beneath the chart says: "The regions of the difference spectrum with 95% statistical significance that the differences shown are nonzero are shaded with vertical gray lines." The number of such shaded areas is striking, particularly in Figure 5 (b). If you superposed the 3 charts (a), (b) & (c), the CO2 absorption band would be almost entirely grey, indicating uniform difference from 0 across the band. For you to prove your conjecture, you must demonstrate that these regions of statistically significance differences are of no consequence. Your handwaving explanation (above) just does not cut it. So I am sure where this came from: "...so the bottom two graphs on that figure (which look at deltas over 27 and 33 years) show a rise or no change in OLR emission in the spectrum associated with CO2 absorption" I repeat: the graphs show a statistically significant difference from 0 over substantial regions of the band. You can't argue black is white. This has nothing to do with time windows. The guys at RC prbably are top notch for climate science, but time windows are no part of the point I am trying to get across to you. The points you raised were interesting, and thank you for what we have all learned here. But your article at AT is grotesquely triumphalist in tone and should be retracted. -

The Arctic seems to be warming up. Reports from fishermen, seal hunters and explorers … all point to a radical change in climate conditions, and hitherto unheard-of high temperatures in that part of the earth's surface. … Ice conditions were exceptional. In fact so little ice has never before been noted. The expedition all but established a record, sailing as far north as 81 degrees 29 minutes in ice-free water. … Many old landmarks are so changed as to be unrecognizable. Where formerly great masses of ice have been were found, there are now often moraines... At many points where glaciers formerly extended far into the sea, they have entirely disappeared. - - - The above alarming excerpts were taken from an October report to the US Weather Bureau. October 1922, that is, not 2009. So it has happened before, and will happen again. We should not think that everything is so special for our time: the contents of this site strike me as very centered around here and now. It is 10 years this, 30 years that, highest since record began in 1978, and so on. That is a very short time perspective. Somehow the lack of perspective in the climate discussions remind me of the 2000+ year old quote attributed to Socrates that most people would place in our time frame: "The children now love luxury; they have bad manners, contempt for authority; they show disrespect for elders and love chatter in place of exercise. Children are now tyrants, not the servants of their households. They no longer rise when elders enter the room. They contradict their parents, chatter before company, gobble up dainties at the table, cross their legs, and tyrannize their teachers." It is presumptuous to think that mankind rules the earth's climate. There are other, more powerful, forces in play. But we think we can raise or lower the average temperature of the earth at will! 0.33 degrees up, or why not 4 degrees. Or raise the oceans, 38 centimeters up, or why not 6 meters, or whatever ! Invent a figure, and people will bow to you in awe. Ridiculous. Anything could happen, and probably will, but we are not in control. -

Marcus: Slight correction to your post #12 - Carbon-13 is stable and the reason fossil fuels are relatively depleted in C13 isn't radioactive decay, it's photosynthesis's affinity for lighter isotopes of carbon. The decay of Carbon-14 means it has very low concentrations in fossil fuels, and therefore burning fossil fuels should lead to a decrease in both C14 and C13 concentrations in the atmosphere (according to the Suess effect), but C14 is complicated by factors such as nuclear testing which greatly increased the atmospheric concentration. -

Berényi Péter (61) wrote: "Kinematics, uniform acceleration. You've forgotten to divide by 2." I see the confusion. As Jeff (63) pointed out, I took your statement about fitting a quadratic function to be in the form: h0 + v*t + a*t^2 All my computed data is in this form. Berényi Péter (61) wrote: "Linear component is trivial, does not add much, depends on place. No accelerating acceleration (i.e. no jolt, snap, crackle, pop, etc.), no scare." The linear rise rate is actually the dominant part of the sea-level rise projection in my polynomial equation of the NY data. If the acceleration term were dropped, you're still looking at 20.5 cm rise by 2100 and over 42.8 cm by 2200 (the acceleration term only adds an additional 12.3 cm by 2100 or 33.4 cm by 2200). However you look at it, the current trend line from NY guage data shows an expected sea-level rise of an additional 32.8 cm by 2100 and 76.2 cm by 2200. I'd call those extremely low-ball estimates, since the ice sheet dynamics haven't yet really come into play and there was very little global warming during the early part of the NY tide guage dataset. If I start my NY guage data projection fit from 1950 or 1960 (vs. 1856) there's a significantly more rapid acceleration component. I'll gladly post the data, if anyones interested. Though my analysis here is much too simplistic, it certainly helps convince me that Siddall's results appear quite reasonable. -

1077 - "Science is only used in support of one or the other political position." Your partially correct. The evidence can be used to support one position or the other. We all take positions for different reasons. But the argument doesn't work in reverse. The collective process of science itself is as a-political as any process we can use. The peer-reviewed process, isn't perfect, but it does move us in the right direction to the facts. The process mitigates personal biases and agendas. But the evidence supporting ACC is what it is. Backed up by numerous, independent measurements. The process to get to this point isn't political. Now, twisting the facts, and simply denying that evidence can and does serve political purposes. But, that's not science. John's article was dead-on. -

RSVP - Follow up on my post #28. I see a lot of blog posts and radio appearances by Archibald, but no peer-reviewed work by this Geologist. I did find a critique of his methods at realclimate: http://www.realclimate.org/index.php/archives/2007/10/my-model-used-for-deception/ So forgive me if I'm a bit skeptical (aren't we all?) of the point of page 46 (post #5), if it hangs on claims that can't be supported in peer-reviewed literature. -

Thanks to satellites we can be confident that sea levels have risen 55 mm in the last 17 years. That works out at about 320 mm/century. The 20th century rise was <220 mm so it seems plausible to suggest that the 21st century will see a rise in sea level greater than the last century. However, the 750 - 1,900 mm predictions by 2100 sound high given the current rate of rise. We may be in danger of missing the big picture by agonizing over what may turn out to be small, short term fluctuations. My understanding is that sea levels have risen by ~360 feet in the last 9,000 years. That works out at an average of 4 feet/century or 1,200 mm/century. My conclusion is that the rise in sea level is a good thing because it will be accompanied by longer growing seasons in the high latitudes and eventually the de-glaciating of the poles as in the Eocene. I don't buy your sea level "Catastrophe". Rapidly falling sea levels on the other hand will constitute a "Catastrophe" as they will be accompanied by famines on a horrific scale.
