Global warming impact on tropical species greater than expected
Of some interest to this thread is the related Flowers blooming earlier now than any time in last 250 years discussion. I suspect that some of the more successful tropical species will be the ones that migrate pole-ward, as invasive species in the temperate zones. -

headpost: "Plants prefer carbon-12 over carbon-13. This means the ratio of carbon-13 to carbon-12 is less in plants than it is in the atmosphere." Does this preferential uptake of carbon-12 also apply to corals and their algal photosymbionts? -

Chris: From your link to coldest winter in 13 years: "This winter was still warmer than the long-term average." When we claim winters warmer than average are now cold that tells us what the trend is. From coolest September in five years: "The city had an average maximum temperature of 21 degrees, making it the coldest September in terms of daytime temperatures in three years. This is despite being warmer than the long-term norm of 20." Have the last five Septembers been the hottest five on record? If we limit our records to a single year it will always be the coldest year. -

BP, Where is the causal link between lead in gasoline and a specific injury to children? tThere is lead in the environment and also in paint. When scientists learned how dangerous lead is it was banned for all uses. Now, 40 years later, people are not getting exposed to lead like they were. Oil companies claimed it would make gasoline much more expensive, but they were wrong. It is the same with CO2. BP and RSVP, your claim that CO2 is "different" is ignoring the facts about previous pollutants that were controlled. If you ignore enough facts you can support any argument you like. -
adelady at 01:43 AM on 12 October 2010Global warming impact on tropical species greater than expected
Praise be. But what really concerns everyone is just how infrequent the record cold temps are compared to the frequency of the hot record temps. I really do not want to see what might happen if there were no record cold temperatures showing up anywhere in the world. Or is that comment related to the view of warming being like transposing music? I see so many people saying that if it's warming why can't I look forward to things being milder where I am (UK or US). It's not supposed to be like transposing a piece of music up a third from C to E. It's more like a couple of toddlers joining you at the piano and banging discordant keys anywhere and everywhere. -

@Ken: don't be so arrogant when you keep missing the same point over and over again. In fact, by saying that "well-mixed greenhouse gases" is the same as "positive AGW forcing," you confirm the point I was making - and admit it's false to claim that it was a zero in 1750, because there *were* greenhouse gases in the atmosphere back then. Again, the reason these start in the middle of the graph is that the graph measures deltas, not absolute values. Wrapping your ignorance in a big layer of jargon isn't going to make it any more valid, I'm afraid. (See, I didn't even need to put numbers in my post to demonstrate yours was wrong. That's called logic - you should try it sometimes.) -

Tom Loeber - The post you are referring to here was from me. I was following the request of the moderators to move the discussion to a more appropriate thread. You were asked repeatedly to move the discussion yourself; the deletion of off-topic posts (off topic in the ice age thread) has been a standard of this site since it began. It's worth reviewing the Comments Policy. That wasn't a cross post at all - it was a redirection to the appropriate thread. If we don't try to keep on focus in our discussions, it makes it impossible for anyone else to (a) see relevant postings and to (b) contribute to an ongoing exchange. If we toss useful information onto a thread where nobody will ever think to look for it, we're wasting our time! -

muoncounter at 00:50 AM on 12 October 2010Arctic icemelt is a natural cycle
The Prince of Cherries is at it again. the ice itself is about to set a record high for the date in the DMI database (emphasis added). BTW, that database includes the years 2005-2010. We are about to set a record high for a specific date in a statistically insignificant 6 year period. Huzzah! With just 3 more years, we draw a different conclusion:
Note that the annual rebound of new ice is always steeper than the melt. And yes, even with globally increasing temperatures, there will still be winter in the Arctic.

I'll finish off the comment omitting some of the links, which are a bit hard to reconstruct. Basically, corals can adapt to some extent to a drop in pH and still make calcium carbonate but apparently at the cost of metabolic stress, which may in turn lead to less efficient growth and/or reproduction. Some species are much more adaptable than others. Temperature rise can lead to proliferation of algae . Temperature rises may also cause metabolic stress. Corals consequently face a potential double whammy. However, it's important to distinguish between reef damage attributable to drops in pH rises in temperature and damage arising from leaching of fertiliser from agricultural land which can trigger proliferation and expulsion of algae (which give corals their characteristic brown red colouration) thus causing bleaching. Interestingly, although corals first appeared in the Cambrian period, some 542 million years ago, fossils are extremely rare until the Ordovician period, 100 million years later, when Rugose and Tabulate corals became widespread. As readers of this site know well,CO2 was much higher in the late Ordovician although temperatures were much lower because solar output was also lower during these periods. At the same time, given the lower temperatures at the time, ocean pH would have been significantly higher as seas would have been more saturated with CO2. Admittedly, the Rugose and Tabulate corals of the late Ordovician are now long extinct and so may not tell us that much about what will happen with modern coral populations or their capacity to adapt to significant drops in pH.Moderator Response: If you could check your links in your comment at 6 above to see if they were what you intended, I think I fixed them. Previewing comments before submitting catches a lot of issues. :) -

Nice new look. Does the increased central column width allow images wider than 450px? I second CBD's suggestion re comments policy, which needs to be up high. There's plenty of room in the right column (I'm not a big fan of twitter feeds on the front page). Would some form of advanced search or comment search be possible?

@ #7 Roger A. Wehage : Perhaps by combining "Plants prefer carbon-12 over carbon-13" plus the food chain starts with "plants" so any byproduct will reflect this preference plus much calcium carbonate in coral reefs being provided by coralline algae, you can find the reason for the value starting below "the measured standard for carbon stable isotopes". I was taught to firstly look for the answers within the system and look for an external event as a last resort. I find this approach not so common every time I read some debate about climate change written in English. Is there something I should know? -

archisteel #668 The KR chart at #623 uses the same data as IPCC AR4 Fig 2.4 forcings which are labelled 'Anthropogenic' (AG my shorthand). Natural Forcing from Fig 2.4 is Solar irradiance. 'Well mixed greenhouse gases' forcing is a sum of CO2, CH4, N2O and Halocarbons - which are termed 'long lived greenhouse gasas' in same Figure. At 2005 CO2 contributed about 1.66W/sq.m and CH4 and the others about 1.0W/sq.m - total about 2.7W/sq.m - which aligns with the green curve in Chart #623. All these AG forcings are supposedly caused by fossil fuel burning and and did not exist before AD1750 - and were pretty small before AD1850. So 'well mixed greenhouse gase forcing' archisteel is in fact the main positive AG forcing - same thing. Maybe a short course in IPCC AR4 would help your understanding. -

Riccardo at 22:33 PM on 11 October 2010The first global warming skeptic
Glenn Tamblyn the gaussian shape was used just to show the behaviour in the wings of the absorption. It's not really a gaussian but a convolution of different broadening mechanisms. The line width of an isolated molecule would be very small. It would be given by the so called natural width, which is a manifestation of the uncertainty principle applied to time and energy. If the molucule is not isolated, the two most important broadening mechanisms are Doppler and pressure broadening. The former is the well known Doppler effect applied to the emission of electromagnetic waves by moving molecules. The speed of the molecules depends on temperature, so the effect will be larger at higher temperatures. The latter is due to the influence exerted by nearby molecules on the emitting molecule. Usually collisions dominate, but there could also be an electrostatic contribution. It depends on pressure (through the number of molecules) and on temperature (through their speed). It depends also on the gas composition, i.e. the species that collide or otherwise interact with the emitting molecule. The broadening effects have been first noted exeperimentally, the theory followed to explain the mechanisms. The reason why different absorption lines have different strength is quantum-mechanical in nature and involves the probability of transition between quantum states. In classical physics terms, we may immagine the strength of the line as dependent on the change in the dipole moment during the vibrations. On passing, this is the reason why O2 and N2 in the atmosphere do not interact with IR waves, no change in dipole moment during the vibration. Absorption strength and line broadening are two really complicated issues; a proper treatment is way beyond the reach of a blog post. I apologize for being so generic. -

Perhaps the answer to my previous question in #7 might lie in the International PDB standard for Carbon Dating. The following definition was taken from the "Volcanic activity" reference in #7. Isotope ratios are, usually, expressed in δ-units. In the case of 13C/12C isotope ratio in carbon dioxide, the δ-value is given by: δ13C = (R13sample/R13reference-1), where R13 represents the abundance ratio [13C]/[12C]. Usually expressed in per mill (‰), it is referred to the PDB-standard material (Belemnite of the Pee Dee formation in South Caroline, [13C]/[12C]=11237.2 10-6). -
Roger A. Wehage at 22:05 PM on 11 October 2010The human fingerprint in coral
What is the justification for starting the delta 13C change at -1.5% in the graph? My first reaction to this post was, "Something must be missing. What about the CO2 12C/13C makeup in ice core samples?" Two articles, and there are others, shed more light on the subject: Preindustrial People Had Little Effect on Atmospheric Carbon Levels in Science Now and Stable isotope constraints on Holocene carbon cycle changes from an Antarctic ice core in Nature. I still don't understand the justification for starting delta 13C change at -1.5% in the graph. At what point in time was delta 13C change at 0%? Volcanic activity can also modify the 13C/12C ratios and bias the measurements. Does the report note any activity in the vicinity and make appropriate adjustments? -

It is hard to understand the extent of such problems but I suspect it will be more severe than Chernobyl but less horrible than Bhopal.
Fortunately the scale is much smaller than Chernobyl and the stuff released is also more manageable (even if its sheer volume is enormous). Neither is it nearly as lethal as dioxin pollution at Bhopal. Still, it is bad enough. However, at least the Danube appears to be saved at the moment due to heroic efforts to neutralize pH of sludge.
We will also see to what extent and how fast Mother Nature is able to mitigate the effects by turning Sodium Hydroxide in sludge to baking soda (Sodium Bicarbonate) using atmospheric Carbon Dioxide. Heavy metal contents of the stuff is controversial. Government experts say it is hardly above environmental levels while Greenpeace claims it is extremely toxic. I think the problem may be some of the metals are bound in water soluble complexes now as opposed to their original insoluble state in source rocks.
I still think treating carbon dioxide as a pollutant in a legal context is a silly move. At the philosophical level one can rearrange concepts any way one likes, but the legal battleground is an entirely different matter.
Neither the liability insurance business nor the judical system can cope with emissions where you can't trace down causal links from those responsible for it to actual persons suffering damage using plain common sense or standard expertise. Therefore if actual pollutants, where this procedure is supposed to be straightforward get mixed up with other stuff in legalese, you get laws that are impossible to implement, opening up one of the richest sources of lawlessness this way.

Some interesting work suggests coral reefs may also be under threat under threat from non-anthropogenic sources of CO2 and other anthropogenic non-CO2 related hazards . The impact of non-anthropogenic CO2 is presented here as a model of the potential impact of anthropogenic ocean acidification. Some reefs, however, seem to have evolved resilience in the face of rises in temperature . It seems some corals have evolved resilience in the face of temperature rises . I note concerns about acidification is presented here as related predominantly to dissolution of calcium carbonate. However, problems with acidification are complex in that acidification impacts more strongly on bleaching and productivity than calcium carbonate formation. I could not find much other material relating to coral resilience to acidity beyond this article in a sceptical source - I did not have the time or inclination to follow up the references in the article but thought I'd include the link for what it's worth. Looking at a peer-reviewed source, it seems that coral symbiota involved in initiation of coral bleaching events show greater capacity to pass on traits associated with resistance to warming than do corals - not a good outlook, if this is correct. At the same time, the appearance of corals in the Ordovician when CO2 levels were much higher (though temperatures lower) may warrant further discussion. -

I've always used the highest resolution the computer can handle, so the change makes the SkS layout now look less like it was designed to fit under a postage stamp. Glad to hear that the 'no more than 800 pixels' web page standard is finally dying. For the right column... I'd suggest that might be a good place for some of the 'hidden' / 'lost' pages. The one that I always have trouble finding is the page where you can put in sort conditions like 'peer reviewed', 'skeptical of AGW', and 'within the last month' to get a list of submitted links. I've found that a good way to keep up on the latest research... when I can find it. Also, the comments policy is linked by the comment box, but nowhere on the main page. I know there have been other pages I've seen once or twice and then lost track of. -

Eric L: the change is per mille. Which is like per-cent, but per thousand rather than per hundred. So it's a fractional change, but to get to per-cent divide the figures by 10. (this sounds small, but it can be a very sensitive test - it's the sort of stuff they use to determine temperatures from ice and sediment cores) -
Mike Palin at 18:35 PM on 11 October 2010The human fingerprint in coral
Eric L- The y-axis scale is given in "delta" units which represent the deviation in parts per thousand of the 13C/12C ratio in a sample - coral calcium carbonate in this case - measured relative to that in the international reporting standard for carbon stable isotopes - PDB, a carbonate fossil (belemnite) in the Pee Dee Formation in South Carolina. A value of -3 indicates that the 13C/12C ratio of the sample is lower than that of PDB by 3 parts per thousand or 0.3%. -
Glenn Tamblyn at 18:20 PM on 11 October 2010The first global warming skeptic
Riccardo I have read a similar description over at RealClimate and the general point being made seems to be that a major part of the increased absorption involves CO2 (and I presume other GH gases in their behaviour) absorbing at some central wavelengths first and this absorption then 'spreading' to adjacent absorption lines at higher concentration. You describe it as following a gaussian distribution. The point that isn't clear is why, if CO2 has a range of absorption frequencies, the central lines would absorb preferentially and thus saturate first. Why don't we see equal degrees of absorption across all the absorption lines. All the descriptions I have read to date make good sense apart from the explaining the causal mechanism of WHY that gaussian spread occurs. Is this theoretically derived, observational, what? This seems the only missing piece in the puzzle as far as an explanation of this goes. -
Eric L at 17:24 PM on 11 October 2010The human fingerprint in coral
I find the y-axis of the graph a little confusing -- it appears to be a negative percentage change, but it isn't clear what the baseline the change is being measured against is. Also, one thing you could make clearer is that I don't think the total amount of C13 in the atmosphere is declining, it is the percentage of all CO2 which is C13 that is declining. -

Re: The Inconvenient Skeptic As scaddenp rightly points out, you are in error. The atmosphere is layered, like an onion. The different dataset sources measure different things. Attempting to homogenize them into a "blended" dataset is less like comparing apples to oranges than it is comparing apples and breadfruit. Attempting to shift the focus of the debate to "skeptics using satellite only and the AGW crowd using CRU only" is also misleading. Scientist use the theory that best explains the preponderance of the data. Multiple, independent lines of evidence (of which station data and satellite data are but two) show that our world is warming and that we are causing it. That is what science is telling us. Most "skeptics" choose to focus on part of the evidence available rather than all of it. I can appreciate wanting to roll all of the instrumental data (station and satellite) into one neat package, but it isn't necessary. It's rather like combining the four Gospels into one continuous narrative: while interesting, it doesn't tell us anything we don't already know. The Yooper -

Well me, if I wanted to know what is going on in the surface record, I would use the surface temperature record. If I wanted to know what is going on in lower troposphere, I would use MSU data. Giving the complexities in the relationship, I would certainly not be interested in a combination, least of all one put together with arbitrary weightings. What would you think of someone doing this in your area? Think you could get such an approach published. I did indicate how you would combine them properly but first you solve a very difficult problem. Also, the idea that "skeptics" use satellite and AGW use surface is bogus. It is use for what purpose. -

Weeds are perfectly ordinary plants in the 'wrong' place. Noxious weeds are those in the wrong place whose vigour threatens an environment or a crop. There are good reasons for authorities to ban or control them. (There's a similar argument about vermin and other pest animal species.) Pollutants are substances in the wrong place and /or the wrong quantity. (Flooding other than normal predictable water flows for the area is in the same category.) Authorities have good reason to insist on proper drainage arrangements for their own and for private property. They also have good reason to regulate all sorts of things from tanneries to chemical factories to private incinerators - write your own list. Very few of the things that need regulating, controlling or eradicating are "unnatural" or inherently poisonous. They're the simple consequence of human activity. Careless or thoughtless activities like those that introduce vermin or weeds or overflows to an area. Others involve lack of foresight or knowledge when undertaking actions like introducing cane toads to Australia or choosing to expand coal fired power technology around the world when other options were available. Regulation, control or eradication are all appropriate responses when the dangers are known. -

Doh!!... Those darn links... Working link. I did indicate that the satellite measurement is a measurement of wavelength. I am not saying that it is perfect method, but none of them are perfect. Hadley and CRU also give different results. This is the one place where anomaly is beneficial. I think it is a more useful method than all skeptics using satellite only and the AGW crowd using CRU only. Instead of arguing about interpolation methods and UHI I am using more sources of anomaly data. If you have a better proposal for incorporating satellite data into a standard record I am all ears. I don't particularly care what method is used, but a single set that attempts to use the station and satellite data would be helpful for all. -

Try reading up on how MSU measurements are made, corrected etc. ALL of them valuable, all of them show a warming trend.

Using only station records when there are two versions of satellite data available is a form of cherry picking. Since those are limited time wise, I propose that a compromise set be used. This is the set I will use from now on for the instrumental period. It is a merged set that uses the CRU, Hadley, UAH and RSS. Details are available on my site as well as the file. No set is perfect, but I hope that using a set like this is acceptable, more reliable and reduces the complaints from each side of the debate on which set of data they use. http://theinconvenientskeptic.com/2010/10/what-global-te…rement-is-best/ John Kehr The Inconvenient Skeptic -
