Gawd, I hate misleading headlines.
"Natural gas won't save the planet, says new peer-reviewed report"
It should say "Natural gas without supporting policy won't save the planet, says new peer-reviewed report", because that's what the study says.
If there's good policy on things like curtailing fugitive gas and carbon prices, it can work. Otherwise, it's not going to help that much.

Interested party,
You would be better off studying climate science that chaos theory when you want to comment on a climate board. The natural trend now is cooling. Without human influence the temperature would be cooler. Your general comment seems to suggest it is impossible to know anything. Scientists feel we can learn and project what needs to be done.
Perhaps you can sugggest a specific topic you want to discuss and we can help you figure out what you want to learn.

Ok, so it is important to rebut obviously innacurate models (i.e. no pressure broadening and LW "windows" to space)
HOWEVER,
If the Durack et. al estimation is correct and ECS is now pushed much higher, (with associtated TOA values pre 2005 much higher) then we must conclude that the aerosol forcing factor is much greater (negative) than current models hold.
The implications are then that, as China has been radically reducing its sulfate emissions since 2011, we are seeing a regional NH spike in heating (though we are only now experiencing the warming increases).
Further implications are that the anthropogenic signal may now be accurately extracted from the 1910 to 1975 global temperature regime.
If this is true, it changes everything. near and long term temperature responses, incresed near-term land based and permafrost carbon cycle feedbacks, increased regional rainfall and land-based temperature extremes, radically incresed long-range projections for sea level rise. And all of these produce an accelerated damage function in the IAMs leading to an estimation of the social cost of carbon greater than $300.00 per tonne CO2e (with a completely immoral and indefensible 3% pure-time multigenerational discount rate)
In short. If these implications are correct, we have crossed a threshold where mitigation discussions must now take on the urgency as an existential threat, without prejudice. -

hank at 02:58 AM on 20 October 2014IPCC admits global warming has paused
Aside — you'll find many 'septic' sites posting a partial quote from Al Gore's 2007 Nobel acceptance speech (one way to identify that sort of misattribution and spin is to look for their copypaste repeats of the partial quote).
Here it is in context:
"Last September 21, as the Northern Hemisphere tilted away from the sun, scientists reported with unprecedented distress that the North Polar ice cap is "falling off a cliff." One study estimated that it could be completely gone during summer in less than 22 years. Another new study, to be presented by U.S. Navy researchers later this week, warns it could happen in as little as 7 years."

Hans11230 at 06:17 AM on 19 October 2014Breathing contributes to CO2 buildup
I'm sorry to bring up this subject again, but I've only just been introduced to this platform. I have had no previous opportunity of discussing whether " Breathing contributes to CO2 buildup "?When we replace forests bij vegetable fields a lot less carbon is stored in vegetable fields than in forests. The forest canopy is higher and permanent while vegetables are also a seasonal crop.
The differrence in carbon storage has been burned and is introduced into the atmosphere. Therefore 7 billion people needing more crops than 4 billion people will subsequently have displaced carbon from storage in forests to the atmosphere. This is added to the GHG. Breathing will not further increase the amount of GHG as we have to keep growing crops to keep the cycle in balance.
So yes there should be more GHG and I think you can feel this in your bones. But its in facilitating our food that crops are a far less functional temporary carbon sink.
And breathing does NOT contribute to a buildup of CO2 as we will allways have to cultivate new crops to ensure a continual supply to enable future bre -

Phil at 22:30 PM on 18 October 2014How did the UK grid respond to losing a few nuclear reactors?
For a brief time early this morning, Wind was the second largest contributor to the UK grid, and came within a whisker of being the largest
Time Coal Wind CCGT Nuclear 5.20am 5.87 5.578 5.316 4.343 6.20am 7.321 5.99 5.956 4.337
(figures in GW)
Obviously this is cherrypicking; demand at this time is at its lowest, and wind conditions appear to ideal for power generation at the moment. Nevertheless it does indicate that the UK grid can accomodate a substantial proportion of wind power. The interconnector to Holland was also fully importing, suggesting that mainland Europe also had an abundance of wind energy.

Most significant climate papers are published in journals that have a larger base than climate science and so have same process as all the other disciplines. I do hope you will further at the dispersions cast on scientists and peer review than just the misrepresentations by "skeptics". It is not often you get mass resignations of journal editors.

mbryson at 10:52 AM on 18 October 2014Why ice sheets will keep melting for centuries to come
Ranyl: Your first question is the one I logged on to ask. I can understand that the amount of ice makes a big difference, but the rate of warming now, as I understand it, is much higher than at the end of the last ice age. So an inference about likely rates of sea level rise in the future based just on the amount of ice seems to leave something important out.

Please take this as an entirely tongue-in-cheek look at publications and citations, but as soon as I read this thread I was reminded of the old chain-mail take on how to get tenure. I easily found the full text online at this location, with a bit of background info on its origin, but here it is for local fun. I particularly enjoy the third paper cited.
Dear Fellow Scientist:
This letter has been around the world at least seven times. It has been to many major conferences. Now it has come to you. It will bring you good fortune. This is true even if you don't believe it. But you must follow these instructions:
- Include in your next journal article the citations below;
- Remove the first citation from the list and add a citation to your journal article at the bottom;
- Make 10 copies and send them to colleagues.
Within one year, you will be cited up to 10,000 times! This will amaze your fellow faculty, assure your promotion and improve your sex life. In addition, you will bring joy to many colleagues. Do not break the reference loop, but send this letter on today.
Dr. H. received this letter and within a year after passing it on she was elected to the National Academy of Sciences. Prof. M. threw this letter away and was denied tenure. In Japan, Dr. I. received this letter and put it aside. His article for Trans. on nephrology was rejected. He found the letter and passed it on, and his article was published that year in the New England Journal of Medicine. In the Midwest, Prof. K. failed to pass on the letter, and in a budget cutback his entire department was eliminated. This could happen to you if you break the chain of citations.

Riduna at 10:25 AM on 18 October 2014Why ice sheets will keep melting for centuries to come
“When starting with double the modern ice volume or less, sea levels did not rise faster than 2m per century”
Not quite. Meltwater pulse 1A produced SLR of 200m in a thousand years some 14,000 years ago. What unprecedented AGW is now doing to climate and OHC indicates that average global sea level rise this century is going to be a lot more than current predictions of 1m by 2100.
Governments should be planning on SLR of at least 2-4m by 2100 rather than relying on conservative assessment such as this.

I'm not sure what the peer review process really is in Climate Science, although some disquieting emails on peer review in Climate Science were brought to light a few years ago. I suspect it probably is no different from the peer review pocess in my own area where I never found out who peer reviewd the papers I submitted. On publishing in open journals, which seem to be a lot less rigorous in their scrutiny of submitted papers, I write seem as I haven't submitted to such journals, it does add to the body of published work by an academic. Although this may not enhance his/her standing in their particular scientific community, it could be very advantageous in internal applications for promotion where a long list of publications can have a ssignificant positive impact on the university promotion committee

Dikran Marsupial at 00:56 AM on 18 October 2014Dinner with global warming contrarians, disaster for dessert
CBDunkerson, I don't think that is necessarily the case, there are comparatively few skeptics, so even if they all cite every paper each of them writes, that is still a relatively small number of citations for any given paper, compared to the available citations available from the research community in general. A basic newtork analysis would expose their gaming of the system, so there would be little to gain from it.
However, I was more thinking of acedemia in general rather than climate science in particular. If academics no longer have an incentive to write papers that nobody cites (i.e. that everybody ignores), there will be no profit in running a predatory open access journal.

CBDunkerson at 21:44 PM on 17 October 2014Dinner with global warming contrarians, disaster for dessert
Dikran wrote: "One possible solution to this problem is to make promotions etc. for researchers contingent on the citation of their papers rather than merely the existence of the papers themselves."
Unfortunately, I doubt that would work for very long. Given the established willingness of 'skeptics' to game the system, changing the details of the sytem will just mean a brief period of clarity until they adjust by changing their gaming strategy. In this case... if citations are the determinant it seems inevitable that groups of 'skeptics' would get together and cite each other's papers en masse. Even legitimate scientists might be tempted to cite a friend's tangentially related work just to 'help them out'.
Unless some 'ungameable' benchmark can be established, switching the benchmarks only serves to make an even bigger mess in the long run as each standard is deliberately corrupted in turn.
An alternate approach is to play 'whack-a-mole' with each effort to undermine the current standards. In this case, if we take the problem to be publication of dubious research in journals with low standards, a solution might be to establish a means of identifying such journals and excluding them from consideration. No doubt this would lead to cries of 'bias' and 'censorship', but the reality is that various forms of publication (blogs, vanity press, un 'reviewed' papers, et cetera) are already excluded. This would just move the line slightly from including 'anything even ostensibly reviewed' to 'anything reviewed in a remotely competent manner'.

Ashton - The Lindzen and Choi paper was discussed on this thread. Nothing new from the previous 3-4 papers on the same topic, no addressing of the multiple rebuttals and previously demonstrated errors.
The Harde papers references of Lindzen et al 2001, Spencer and Braswell 2011, Salby 2012, Ludecke 2011, etc, are rather blatant examples of relying on wholly debunked works without referencing any of the later and contradicting literature.

A response from Dr. G. Kramm (who is well published in climate studies) on the earlier EIKE thread promoting Harde states (again, my apologies for auto-translated German) with respect to Hardes paper:
[Notes that Harde hasn't cited relevant works]... The rivers of sensible and latent warmth allowed to be calculated only according to local temperature and humidity distributions. Everything else is colored blooming nonsense.
-
Dinner with global warming contrarians, disaster for dessert
Hermann Harde has commented regarding his paper on the EIKE website (German climate denial lobbying group), which has been promoting his paper. My German is quite poor, so I'm relying on Google Translate for this - I expect fluent readers to have more clear information. Some notes and statements from that comment:
- Harde is retired, writing on climate in his spare time.
- "...but generally about the greenhouse effect. It is almost nonsense, of a self-heating mechanism or Perpetuum Mobile to talk..." -this is Gerlich & Tscheuschner level nonsense, and in fact a term straight from G&T; the greenhouse effect is not invalidated by thermodynamics.
- "That the CO2 concentration increases delayed (by Prof. M. Salby about 9 months) due to heating caused mainly by increased solar activity, no one disputes in this county. This has only effect that so climate sensitivity is additionally influence as a feedback or gain to the solar sensitivity." - No, it's not the sun, CO2 increases over the last century are _not_ due to the warming ocean, as oceanic concentrations are rising too, and Salby's nonsense is demonstrably just that.
- "...GCMs turns out here so great that all were not able one and all and to indicate the climate evolution of the last 17 years and also for the near future..." - Ah, the inevitable 'hiatus' comment...
- "Limitations to this, it is only at a underlying thermally induced cloud feedback in the superimposed oscillations and can change the feedback coefficients." - The only feedback in his model appears to be a fixed cloud scaling with temperature. I cannot find any reference to water vapor or specific humidity.
- "Circulation and exchange between different zones I do not treat as a global ECS and no climate sensitivities of individual zones are considered here." - A _very_ simple model.
His starting point is rather worse than I had expected, loaded with climate denial myths. And while his radiative model is quite complex (228 layers - as I understand it line by line radiative code converges asymptotically after about 40 layers), his climate model and it's response to CO2 changes is clearly inadequate to the task.

When I read the name "Harde" I had the bad feeling that another G&T embarassment might show up. To my relief the Rabett states: "Harde's stuff is of a much higher quality than the G&T joke."
But it may well not be much higher, either. The citation base seems to be grounded on known outliers (Lindzen, Spencer...), even Vahrenholts "Kalte Sonne" gets cited. How low can you possibly go? And then this brave retired man gets his applause from web sites like EIKE or "science skeptical" (a kind of german SkS travesty). Like G&T it is one of those 450+ "papers" that EIKE uses to show the real true truth that everything from the Alarmistas is wrong and fabricated (and they never turn down anything from that ongrowing list, even if so debunked and burned that the authors themselves do not mention it anymore).

Jonathan:
What KR and Glenn said. Scattering and absorption/re-emission are different beasts.
Wikipedia actually has an article on Rayleigh Scattering, which in the atmosphere is the scattering caused by the air molecules themselves. Ditto for Mie Scattering, which in the atmosphere is caused by all the particulate matter. In fog, also add reflection (including internal - i.e., inside the water droplets). And in all cases, expect multiple scattering - light that is scattered many times, sometimes to the point where you can't tell up from down (white-out in a blizzard).

Bob Loblaw at 11:48 AM on 16 October 2014CO2 effect is saturated
Glenn @ 308:
A good catch. I had realized that figure 7.3 in that source was not covering the peak absorption wavelengths - hence my reference to figure 7.2 where the right side shows much greater absorption.
Other references I had on hand gave absorption coefficients with units such as kg/m2. When using Beer's Law, you must be careful of units, and typically simple distance (e.g., metres) isn't one you'll see because distance isn't a measurement of the amount of gas - you need density, pressure, etc. to get the full picture. I wasn't about to try to figure it out late at night, and missed the context of figure 7.1. I had also looked at table 7.1 in that document, which gives several possible units for path length, including "cm" and "cm atm". I don't think either one of them is intended to be simple linear distance.
It is possible to measure gas amount in length units, but the length isn't ordinary distance. Take ozone for example, where a Dobson Unit (a common measure of total column ozone) represents a thickness of ozone of 10 µm, when compressed to standard tempeature and pressure. The WIkipedia page also calls that a "milli-atmo-centimeter", so I'm going to guess that the "cm atm" unit in table 7.1 is a similar measure. Thus, just because an absorption coefficient has units of length doesn't mean the path length is really distance or height.
The data from figure 7.1 does definitely appear to represent a physical path in the free atmosphere of 1 metre, though. They refer to 100 and 1000 mb as the pressure, and "typical CO2 concentration".
The PDF file I linked to appears to be just one lecture in a course on atmospheric radiation, and the course syllabus is available here. It looks like it has a lot of interesting material.

I have not heard of any scientists excluded for their scientific reticence about extrapolating negative info, so I think it is a bad precedence for peopl who err slightly on the other side. I would say the former (reticence), all in all, is ultimately more...problematic.

On the methane bomb... There seem to be a lot of good scientists who are skeptical of this idea. Richard Alley, I believe is one who states something along the lines of, maybe, but probably not anytime soon. I've seen others state that magintudes are insufficient to compete with CO2.

I would count any scientist who works in such extreme conditions to also be an 'explorer.' Last year a ship of scientist was in danger in a storm in the Arctic. They were saved, but many who went to save them perished.
Two such brave explorer/scientists are Igor Semiletov and Natalia Shakhova. They just returned from another long and dangerous voyage studying this critical region only to find that, in spite of being the two scientists with the longest history of working in the area, they were excluded from a session at the Royal Academy on just this topic.

"It is to an authors advantage to send their work to a journal that is likely to give them a hard time,"
Yes. In many areas of science (especially where there is real controversy rather than manufactured) , each paper published is a shot fired in a war. It is common around here to suggest as a reviewer the person that will hate the paper most. Such a person is much more likely to put the time and effort into giving the paper an exhaustive review. This results in a much better paper than one that has only had prefunctory review from busy colleagues, even if it delays publication.
-
Dinner with global warming contrarians, disaster for dessert
There are a couple of references to earlier versions of Prof. Harde's work on Rabett Run, here and in the comments here.
The gist of it seems to be that Harde used some quite good molecular data for radiative calculations in a very simplistic climate model without feedbacks (or for that matter oceans) - and that seems to be the case with the current publication.
His result of 0.6 ˚C/CO2 doubling is therefore only comparable to the generally computed 1.1 ˚C of direct CO2 forcing (prior to feedbacks), as per Myhre et al. 1998. By comparison, Myhre used multiple atmospheric profiles with differing cloud levels, and compared three different radiative models for their estimates, which have held up in the literature quite well. I believe that Harde's very limited (and crude) model is responsible for the difference.

Dikran Marsupial at 00:37 AM on 16 October 2014Dinner with global warming contrarians, disaster for dessert
I used to teach a postgraduate course (an afternoon) on how to review a paper, and I usually started by discussing why we publish and what the author gains from peer review (so you understand the aim of reviewing). The main purpose of publishing is so that other people working in our field will read ours ideas, test them, and if they work will use them in their own research. The thing that the author gains from peer review ought to be rigorous criticism that prevents publication of a paper that would be damaging to our research reputation (perhaps because it is wrong, or doesn't support the argument sufficiently well with observational or experimental) and if it is publishable make it a better paper that is more likely to be cited by other researchers who find it useful.
It is to an authors advantage to send their work to a journal that is likely to give them a hard time, as it is the criticism provided by peer review that maximises their chances of having an impact and being cited. If you think you have something that shows a whole research field is wrong, you ought to send it to the top journal, and if they don't accept it then perhaps it is because your idea isn't as good as you think it is and you need to work to refute their criticisms.The important thing in science though is not the source of the argument, but its validity. As others have suggested above, Prof. Harde's method is not actually very advanced, and has a number of obvious flaws.

Thanks for the discussion which is not overly supportive of Professor Harde. From the summaries of the list of reviewers from Tom Curtis I have to agree with Dikran Marsupial that the review panel may lack experience. I also have to agree that Dr Harde might have selected a more apposite and auspicious journal to which to submit his paper. Of course I can't know that he didn't.
I frequently disagree with posters here but on this occasion it is plain that the discussion of the paper here is in an entirely different and better, class from that I have read elsewhere

Dikran @11, here are the members of the Editorial board registered with google scholar.
Chandra Shekhar Prasad Ojha cited 1126 times
water resources, evironmental engineering
Mohammad Hadi Dehghani cited 282 times
Environmental Health, Solid Waste Management, Air Pollution
Mrinmoy Majumder cited 70 times
watershed management, climate change, hydro power, nature based algorithm
Panagiotis T. Nastos cited 1382 times
Climatic Change, Human Biometeorology, Outdoor Thermal Comfort, Urban Microclimate, Atmospheric Pollution
T.N.Singh cited 1729 times
Rock Mechanics, Artificial Intelligence, Engineering Geology, Mining
That makes an avearge of 917.8 citations per editorial board member.
I don't have much perspective on that, but (for example) Kevin Trenberth has 39953 citations, Judith Curry has 12073, and John Church has 9905. It appears then, that they are on the lower end of a respectable citation results. However, the connection between their output and the journal's subject matter seems a little stretched in most cases.

Tom, the h-5 index of the journal would indeed be a useful metric if it were available, however in its absence you can look at the h-indices of the editorial board. If the editorial board are not experienced leading researchers, it is likely to be a recipe for errors in the peer review process (c.f. Pattern Recognition in Physics)
It isn't immediately clear to me why a truncated icosahedron would be more mathematically tractable than a sphere!
