Tom Curtis at 08:59 AM on 24 August 2012How much has nuclear testing contributed to global warming?
vroomie @4, thanks, and fixed. Byron Smith @1, this is certainly not the loopiest idea I have ever seen from AGW "skeptics". The most bizarre is the idea that it is radar that is causing global warming. The next most bizarre is that not only is geothermal energy causing global warming, but the relatively temperate climate at the Earth's surface is entirely caused by geothermal energy. The theory that nuclear weapons is the cause involves primarily a simple failure to grasp the scale of the energies involved. Consequently it will have an intuitive appeal to the scientifically uninformed; but fortunately only to a very few on the sidelines. -

scaddenp at 07:23 AM on 24 August 2012Global Warming - A Health Warning
John, since by definition there is no convection operating above the tropopause, I would say the "incursions" by diffusion would be too small to be measurable. Furthermore, it is only persistent in cold, dry condition. Within the lower troposphere, its half-life is a matter of days. -

Andy Skuce at 06:35 AM on 24 August 2012Sea Level Isn't Level: This Elastic Earth
The "crust" is actually the lithosphere, which is not that weak or that thin (100-200km) and the stuff underlying it is not exactly fluid either, being many orders of magnitude more viscous than pitch. Perhaps a better analogy for isostasy would be a water bed filled with peanut butter, overlain by a two-inch thick rubber sheet. -
Pete Dunkelberg at 06:34 AM on 24 August 2012Teaching Climate Change in Schools
Michael Sweet @ 8: "I address AGW by assigning a several reports where the students look up their own data and write reports on sea ice or global temperature." Yes! Do it that way. What is your physics teacher's argument? Is he a "2nd law of thermo forbids downwelling radiation" type? Why on earth is it hard to address the "grant money" argument? That's about the trashyist argument there is, and an opportunity to explain what science and scientists are all about. Grants have been well addressed at RC sometime ago. Obvious factors start with: 1. The first criterion for getting a grant is that the proposed research will advance scientific knowledge. You don't get or need a grant to say what everyone else is saying, nor do you need to do all the work of research. 2. You don't get the money anyway. The money goes to the institution. First they take their "overhead" off the top. Then they disburse the remainder in bits as graduate student or postdoc stipends, or to suppliers for equipment, etc. When you get a grant, what you, the researcher, get is an obligation to do a lot of work. Why would you do that? see below. 3. If it is money you are after, and you are enough of a scientist to do original research in earth science, you can make much more money working for industry. which brings us to what scientists and science are all about: *** Finding things out is what it's all about *** That's the first realization your students need to start understanding scientific methods. Then you get into How to find things out. But you won't get far without a drive to find things out. Michael, learn to take that trash "grant money" argument as an opportunity. ... then finally point out that it is not a scientific argument - is it an implicit admission of not having one? If not, back to your Assign a report method. ======= Steve @ 12: "When we first take physics, we start with Newton. (Don't we?...." Well there's http://www.physics2000.com/. ======= @ 16 "If children *see* a container of C02 getting warmer than one of air, Linda's first co2 experiment ...." search on Linda's first CO2 experiment. As for wanting teachers to cover all those other things you mention, by and large they are struggling to cover what they have to (their state standards) while following the text and preparing the students for standardized tests - three sometimes contradictory aims. -

Pete Dunkelberg at 05:22 AM on 24 August 2012New research from last week 33/2012
With polar ice volume decreasing faster than models predict, we had better note the "at least" aspect of the predicted sea level rise. Semi-empirical projections may also not take account of losing our coal-induced aerosol cover, hopefully well before 2100. As for after 2100, what was sea level the last time CO2 went above 400 and stayed there for a good while? Above 450? -

Steve from VA:Climate scientists are part of pop culture as well. Not everyone can be a real climate scientist which is why individuals like Pielke and Monckton gain credibility ... I've long thought that Monckton's special influence in the U.S. and Australia hinges in part on atavistic cultural impulses to do with his peerage, plus of course his toff accent and appealingly florid writing. Just because you're no longer a colony doesn't mean you instantly abandon the instinct to knuckle your forehead. Does it help to know that Chris Monckton is a lord only because his grandpa was a politician shunted out of government over disagreements with Anthony Eden and given a consolation prize of peerage, that the current Lord Monckton wasn't even born a peer? Probably not; Brits don't care that Lady Gaga is the child of a NYC city couple of humble origins, but Lady Gaga gets the power of "Lady" in front of any name. -

Byron: I thought I was familiar with pretty much all the myriad loopy dissenting arguments. Me too. There are a lot of problems with this idea beyond the basic erg deficit. I don't think nuclear weapons release a new form of energy that is unusually subject to gravitational attraction, weapons testing largely ended a long time ago, yet the energy released in those tests is supposed to be lingering? How? Is a bizarre argument like this a sign of hope or cause for depression? Desperate hail Mary or indicator of a receptive audience whose thinking skills have collapsed and dribbled away like ice cream on a a hot summer day? -
Byron Smith at 03:22 AM on 24 August 2012How much has nuclear testing contributed to global warming?
I thought I was familiar with pretty much all the myriad loopy dissenting arguments. This one took me by surprise. There are some very important historical links between nuclear weapons and climate science, since the rapid improvement in atmospheric monitoring and modelling that occurred after WWII was very significantly driven by the desire to learn more about the likely fallout distribution of nuclear explosions. I read a fascinating article drawing many of these links, though can't find it right now. -

steve from virginia, I disagree. I think the solution is that world leaders -- indeed leaders at all levels -- need to be above falling for denial shenanigans, and to actually lead. If the world leaders (including USA Republican presidential candidates, for example) were united and serious about things -- recognizing their need to be mature and intelligent in everything, especially an issue with such gravity as this one -- you wouldn't have nearly so many people watching the Marx brothers versus the Keystone Kops and getting confused. We don't need scientists pretending to be salesmen or conmen, we need leaderspretending to beacting like leaders. -
Bob Lacatena at 01:50 AM on 24 August 2012Global Warming - A Health Warning
From the Carbon Dioxide Information Analysis Center, concerning ozone levels in ice core proxies:The short atmospheric lifetime of ozone (hours-days) together with the spatial variability of its sources precludes a globally or vertically homogeneous distribution, so that a fractional unit such as parts per billion would not apply over a range of altitudes or geographical locations. Therefore a different unit is used to integrate the varying concentrations of ozone in the vertical dimension over a unit area, and the results can then be averaged globally. This unit is called a Dobson Unit (D.U.), after G. M. B. Dobson, one of the first investigators of atmospheric ozone. A Dobson unit is the amount of ozone in a column which, unmixed with the rest of the atmosphere, would be 10 micrometers thick at standard temperature and pressure.

Denial is part of pop culture, part of mainstream industry marketing. The denial approach works because modern culture's inherent false-ness: everything we engage with is fashion, that being trendiness, desire (the latter a business good), frivolousness/triviality and contrariness-for-its-own-sake. Modern, post-WWII culture is 'girlish' and erratic, vamping and gay (homosexual); pornographic, inconsequential and theatrical. Business isn't presumed to behave this way (where is that bottom line, again?) but business is a component of culture -- not the other way around. Business conforms to roles culture sets out for it. One role for business is the gay outlaw: business as misunderstood/evil and all-consuming: businessmen are therefore evil and cannibalizing, they have no choice. Saintly businessmen cannot compete because culture has created a business environment that gives evil businessmen various social and economic advantages over the rest. Climate scientists are part of pop culture as well. Not everyone can be a real climate scientist which is why individuals like Pielke and Monckton gain credibility that eludes actual scientists: they self-create the terms of their own 'success', they are democrats who open up the science process: they 'speak truths to power', they are 'scientists for everyman'. The process of democratization is what matters, not content: in America (and its copycats) every mediocrity can become a great artist (Warhol) a great musician (Snoop Dog), a great writer (EL James) simply by 'flaunting convention' (mom and dad), branding themselves in the process. There is nothing more: anyone can be an 'instant rebel without a cause' in the (fake) tradition of (fake) James Dean. Why not fake scientists? What's so special about scientists? The fake scientists are chosen because of how they look, dress and speak, where they are from and whom they know rather than any quality of thought or research, 'qualifications' or relationship to 'facts'. Real scientists are boiler tenders who are required to mind to the machines and keep them from blowing up. Because of how pop culture inverts priorities, the fake scientists are real: the real versions lack the social status to get anyone to pay attention to them. Scientists are constrained to the boiler-tenders' role: to invent technology. When scientists speak out, they cease being tenders and technologists, they cease being scientists -- as determined by role -- at the same time. The social role of 'scientists' is determined the fakes then filled by them. Scientists chasing deniers in newspapers is like Marx brothers being chased by Keystone Kops. Uh ... you guys are the 'Kops'. "Ha ha! Very funny. Look at those dumb scientists!" Because the dead-end kids can always outmaneuver the 'kops' in self-created (theatrical) contexts the kids are made out to be smarter in their own (self-created) way than the smarty-pants scientists. The only possible hope to blow this business up is to draft some photogenic, charismatic 'real' fake scientist like Captain Kangaroo or Rod Serling. Put this individual on TV as frequently as possible telling folks as graphically as possible how their grandchildren are going to die because of global heating -- use that term 'global heating'. It's scary, it frightens people. Nothing else will do. Science has to compete with non-science on its own (false) ground and not shilly-shally around. Part of pop-culture is apocalypse: best to start making use of it! Nobody takes anything seriously in America unless there are bodies in the streets. By then it is too late ... Plan B is for the scientists to start preparing for that day: coming up with lists of things to be jettisoned so that some humans might survive the next 500 years. Start with getting rid of the cars, all of them. Step two is getting rid of industrial agriculture. Any possible response to climate change that does not include getting rid of all the cars as the first step has not one shred of credibility. Otherwise, overpopulation -- of cars and humans -- will take care of itself. A question: how many climate scientists have cars, vacation 'homes', flat screens? (sigh ..)

Dale,You also didn't explain how proxy O3 records show pre-1800 ozone levels being stable for thousands of years, when if as you say temperature affects ozone production, proxy levels should rise and fall with the temperature proxies over the centuries.
You say this because you don't understand the problem or the chemistry. 1) Do you really think that Greenland or Antarctic ice cores can in any way reflect the frequency of unusually high peak afternoon ozone levels at the surface in specific locations (e.g. Houston or Los Angeles or Sydney)? 2) Anthropogenic pollutants absolutely are a major factor, and I will grant you that those did not exist in the past. I will also grant you that if we could completely eliminate such pollutants, this aspect of global warming might be considered minor, because without the pollutants, ozone levels might rarely reach dangerous levels (I don't know that, I'm putting it out as a possibility). But seeing as how many climate ostriches there are in the world, not to mention pollution ostriches, do you really think that we can ignore global warming because we are going to completely scrub the air of all other pollutants? Come on Dale, you're not even trying. Climate ostrich. -
Bob Lacatena at 00:03 AM on 24 August 2012Global Warming - A Health Warning
Dale,The irony of your list of links is that none of them discuss temperature regulating the construction of ozone
Can you read? Are you really in that much denial? You really need to flat out lie in your posts, when anyone who wishes to can check the veracity of your claims? [Note to all participants: In the future, whenever Dale posts lies, please link directly to this thread.] From the Nasa link, under Ozone and Climate at the Surface:In general, an increase in temperature accelerates photochemical reaction rates. Scientists find a strong correlation between higher ozone levels and warmer days. With higher temperatures, we can expect a larger number of "bad ozone" days, when exercising regularly outdoors harms the lungs.
From the EPA link:Many factors impact ground-level ozone development, including temperature, wind speed and direction, time of day, and driving patterns. Due to its dependence on weather conditions, ozone is typically a summertime pollutant and a chief component of summertime smog.
From the first IPCC link:...strongly relate to ambient levels of sulfur dioxide and ozone and to temperature...
andMany studies have focused on the relationship between temperature and ozone concentrations (Wolff and Lioy, 1978; Atwater, 1984; Kuntasal and Chang, 1987; Wackter and Bayly, 1988; Wakim, 1989). For example, the large increase in ozone concentrations at ground level in 1988 in the United States and in parts of southern Canada can be attributed, in part, to meteorological conditions; 1988 was the third-hottest summer in the past 100 years. In general, the aforementioned studies suggest a nonlinear relationship between temperature and ozone concentrations at ground level...
andRegression analyses have revealed that high temperatures are a necessary condition for high ozone concentrations at ground level;
From the Union of Concerned Scientists:Here’s the connection: warmer temperatures increase ground-level ozone. That’s why we hear warnings of “bad air days” due to ozone pollution most often during the summer and on cloud-free days.
From the Environmental Literacy Council link:Ozone is not emitted directly into the air; it is formed through a complex series of reactions from nitrogen oxides, volatile organic compounds, and sunlight during periods of elevated temperature.
andGround-level ozone levels increase in the spring and summer when there is more sunlight and temperatures are higher. Formation of ozone is lowest in the morning and highest in the late afternoon when sunlight intensity and temperature peak.
From the North Carolina Division of Air Quality link:Ozone is primarily a problem during the summer months, when heat and sunlight are more intense. Ozone levels also vary on a daily basis. Ozone levels peak in the afternoon, when temperatures are higher.
From the government of New South Wales link:Hotter temperatures resulting from climate change can reduce our air quality by creating good conditions for particle pollution and ground level ozone.
From the second IPCC link:Formation and destruction of ozone is accelerated by increases in temperature and ultraviolet radiation.
From the Australian government Dept. of lots of stuff link:Ozone is one of the main photochemical oxidants. ... Environment agencies measure the level of ozone because it indicates the total amount of photochemical oxidants in the air. Cities that have abundant sunshine over periods of time, together with moderate winds and high temperatures, are most likely to experience high levels of photochemical oxidants.

Dale, more and more, you are sounding like a troll, and if not, purposely and willfully ignorant, in the sense of ignoring blatant references to what you assert is not said. You: "A couple discuss how temperature can affect the amount of precursors, but none say "temperature increases ozone production." From the North Carolina link: "Ground-level ozone forms when nitrogen oxides (NOx) react with volatile organic compounds (VOCs) in the presence of sunlight and heat. Sunlight is necessary to start the chemical reactions that form ozone, and heat is important to make the chemical reactions more efficient." Just how do you interpret that statement as 'temperature doesn't cause O3 production? From the same source [asterisks mine]: "Sunlight is necessary to start the chemical reactions that form ozone, and *heat is important to make the chemical reactions more efficient.* Ozone is primarily a problem during the summer months when long days deliver plenty of sunlight and when temperatures are warmest. In most areas of North Carolina, ozone levels peak during mid-afternoon through evening, when temperatures are higher, then drop at night, and are lowest around dawn. However, at high elevations (above 4,000 feet) in the mountains, ozone levels can remain high throughout the day and actually reach their highest values overnight." Dale, it really appears that you are *not* concerned with pursuing scientific truth, but simply engaging in Gish Gallops of mis/disinformation. -

Ostricheyed is what deniers are when they look at rising temperatures and see natural variation, or they look at melting arctic ice and see natural variation, or they look at an ostrich-load of extreme weather events and they see... you guessed it, natural variation. Ostrichfied is what deniers do to any science that they choose to willfully misinterpret (such as the 2nd Law of Thermodynamics). -

Dale, Follow some references. Learn instead of trying to instruct. Dozens upon dozens of documents, from NASA to the EPA to individual scientists state that increased temperature increases ground-level ozone levels. Basic chemistry, two steps: O2 + uv --> O + O [UV breaks O2 into 2 separate O] O2 + O --> O3 [A collision combines O2 with O to make O3] The first step depends on UV. The second step depends, as is very common in chemistry, on collisions. Increased temperature increases the velocity of the molecules and through that the number of collisions, i.e. the chance of the reaction taking place. Readers can: 1) Believe you 2) Believe a plethora of qualified scientists, chemists, and scientific organizations (NASA, the EPA, the IPCC, the Union of Concerned Scientists, The Environmental Literacy Council, the North Carolina Division of Air Quality, The government of New South Wales, the IPCC again, the Australian government's Department of Sustainability, Environment, Water, Population and Communities).

Sphaerica (-Snip-) Photolysis is the chemical breakdown due to LIGHT not heat. Heat plays no part in photolysis. This has been experimental proven and is actually a first year chemistry experiment (exposing various gasses to bursts of light and observing). Natural ozone production/destruction is a balanced process. The seasonal variation of biogenic NMVOC's is stable and shown via ice cores and proxies to be stable pre-1800 for thousands of years. And yes, this is during temperature fluxes over time. If heat had anything to do with it, then you would expect ozone to vary with temperature pre-1800. Post 1800 industrial processes have increased ozone production/destruction to the point where anthropogenic and natural sources of precursors are about the same in industrialised areas. In rural areas, NMVOC's are still the main component of the ozone cycle. Two things that can impact the levels of biogenic NMVOC's is CO2 and stratospheric ozone incursions. CO2 causes plants to reduce the openings in the stomata which reduces the amount of biogenic NMVOC's. As stratospheric ozone recovers (due to Montreal) we should expect to see increased stratospheric ozone incursions into the troposphere. So the bottom line is, as I've been saying GW has nothing to do with ozone production. If it did, that would show in ice cores and other proxies pre-1800. Thankfully due to EPA controls and Montreal human based precursors are dropping. But surface ozone is not something that can be completely eliminated because of biogenic NMVOC's. BTW, here's a nice little study which actually states clearly that temperature had no affect on ozone creation in Siberia. And there's plenty more where that came from. (http://adsabs.harvard.edu/abs/2012EGUGA..14.4533S) Here's also another nice PPT which describes the entire process very nicely. (http://envsci.rutgers.edu/~rodenburg/522/photo.ppt) I go back and put my head in the sand now.Moderator Response: Inflammatory snipped. -

Andy, somewhat tangential, but in line with your post at 12. And The Band Played On I *lived* through those dark years, lost more than a few friends to the inactions of He Who Shall Not Be Named (as documented by Shilts, that name rhymes with Kagan), and now, ever so depressingly (except now I *are* a scientist) I'm seeing he same denialist claptrap about an issue that may well have much further effect on the planets' population, as a whole. Make no mistake, I do not minimize the importance of HIV/AIDS in the entire pantheon of humanity's ills, but if we make the planet hostile to just everyday life, HIV/AIDS will pale in comparison. I find it a ~very~ difficult thing to remain in my scientists' 'face of calm,' when engaging in a debate with a spittle-spewing denialist, irrespective of what verifiable scientific fact or rationale s/he may be railing against.

"Perhaps MIT really isn't as good as it would have us believe." Mmmmphft! Mmmmphft! (snipped observation)--amned Beaver rings! >;-) Your point is well-taken; someone posited that shame was likely the only solution but, given the extreme amount of attention they've gotten, methinks the FF-funding smothers that in its volume. Shame seems to be a quaint old idea, these days. It's all a mystery to me how this topic *ever* became such a political football, but...see aforementioned FF funding. What they have to throw against their opponents makes what the tobacco industy used seem like a virtual greenback peashooter. -

Rob Painting @ 28 You are preaching to the converted. I just wonder how many times this site must expose respected climate scientists dishing out myths and falshoods before we get some political action. I have to assume that not all politicians are bought by election donations. Some must be acting on what information they have seen. If that was false, then they need to be made aware somehow or other of that fact. Perhaps the experience of this summer might help some of the brighter politicians look at climate change with an open mind instead of an open mouth. I don't think that there is a cat in hell's chance of Lindzen suing Dana. But wouldn't it be nice for MIT to enquire why he tolerates being describe in such manner. After all, that MIT tolerates a professor who can be desribed thus without reacting does reflect on MIT itself. Perhaps MIT really isn't as good as it would have us believe. -

dana@27...a case of 'the [climate change fake skeptic] lady doth protest too much, methinks?" >;-P I, too, am galled at the temerity and hypocrisy seen on WUWT, RC, et al, ad nauseum. It'd be WAY funnier if so many people didn't buy their [self-snipped expletive] version of climate science. -

FWIW: I drove to the top of Mt. Evans (14,265 ft, 4348 m)this past Monday, in my E Type, and it's the VERY first time I'd done that drive (many, many times, over the years, and saw *not a single bit* of snow, anywhere. That is highly unusual. There are numerous other signs in the state as to warming of the globes... The Global Warmings For fun, if I may be allowed, here is last year's drive. Mt.

But, I NEVER heard them use the *delicious* term, 'ostrichism," Sph! H/T for that term! -

Excellent article Dana -- thanks very much. If I can make a suggestion, it would be extremely helpful if someone would write up a basic tutorial on the physics of drought. In struggling to understand basic climate science, I find that when I read some of the papers, the basic physics is somewhat obscured by the complexity of the models. I found within this site, some very helpful discussion in the comments on Hadley cells and the intertropical convergence zone, but it's not pulled together into a coherent picture for me yet. So for example, I read the very recent Dai (August, 2012) paper and the regions where the models most disagreed with the observational data was in the US and the Sahel -- the observation being that in the recent past the US was wetter than expected and the Sahel dryer. When Dai projects ahead the model then predicts it to be dryer in the US and wetter in the Sahel. What's the physics here? In the quote above from the Revkin article, Dai says it's been colder in the Pacific since 1999 and he expects it to last 20-30 years. But I thought we were entering an El Nino phase where the eastern Pacific should be warmer? And why is the Sahel expected to have more moisture? Is it that the ITCZ is expected to move North from it's present location with increased warming or for some other reason? As I said, a basic tutorial would be immensely helpful for people like me. Thanks. -
dana1981 at 06:00 AM on 23 August 2012Patrick Michaels' 1992 claims versus the 2012 reality
Steve L @8 - that was me who called Linzen the most consistently wrong climate scientist (reposted by Romm). Michaels definitely gives him a run for his money, though as DB notes @9, it's a bit of a stretch to call him a climate scientist these days, since as far as I'm aware he doesn't do serious research anymore. I think it's fair to say that people treat Lindzen as more credible, given that unlike Michaels, Lindzen doesn't work for a fossil fuel-funded think tank. Regardless, both have been quite consistently wrong on climate issues. I'd say Lindzen is more wrong, whereas Michaels' wrongness is primarily due to misrepresenting others' work. -

Funglestrumpet - Lindzen repeated the CO2 and plant food myth. Mate, even school children know better than that.
