jdixon1980 at 02:04 AM on 14 November 2013Cosmic rays fall cosmically behind humans in explaining global warming
I'm disappointed that suckfish @1 got a down vote. I see no reason to assume his questions were anything but an honest and relevant inquiry.
I do like the way chriskoz and Dana responded with a wealth of information; that's what makes this a great site. That is, with the exception of chriskoz's admonishing opener, "Your assessment is simplistic and incorrect," a mischaracterization of suckfish's comment - suckfish was explicitly airing out an "impression," not making an "assessment," and even inviting the impression to be corrected. All of us get wrong impressions from time to time due to gaps in our own level of understanding/expertise and/or incomplete information, and there's nothing wrong with that. (What can be harmful is precisely when people mistake their own wrong "impressions" for thorough and sound "assessments.") A purported "assessment" would reflect a belief by the speaker that she has considered enough of the relevant data and evaluating the conclusions of others to form her own firm conclusion. It would not be accompanied by a question about what the latest research indicates, and it would not itself be punctuated by a question mark, both of which appear in comment #1.
I don't know if there may be some history related to any prior comments by suckfish in other threads that may have triggered the downvote and/or the (in my view, inaccurate, as explained above) admonishment, which might justify them in a private conversation, but in a public forum it would regardless tend toward giving a wrong impression to anyone unaware of that history that we here at SkS are quick to assume anyone questioning any part of the main post is just a troll to be criticized and condescended to.
I think I speak for the community of regular visitors and contributors (my own small contribution so far consisting entirely of a single Spanish translation of the "ocean acidification is not a problem" climate myth, though I aspire to pick up the pace soon and start adding more translations) when I say we want to encourage honest and relevant inquiry, and that there is no shame in approaching an issue with initial impressions that may turn out to be incorrect.
Moderator Response:[PW} I agree: the never-ending onslaught of denier drivel has had, unfortunately, a corrosive effect on even the most genial of discussions and some--I am not absolved in this either--of us have an 'itchy rigger finger,' when we think we see a concern troll in its initial salvos.
I think it instructive, this bit of behavior and the poster's observations about it, and urge all to give everyone who visits SkS the benefit of the doubt, unless/until they show what their true motives are in commenting here.

Dikran Marsupial at 01:17 AM on 14 November 2013Models are unreliable
dvaytw It sounds to me as if your firnd may be thinking of "flux corrections" but modern climate models have improved to the point where they are no longer necessary. Sadly unless he can give a concrete example, it is difficult to address his concerns more directly. The modellers do however perform experiments to determine the sensitivity to the parameters, which I understand are called "perturbed physics experiments". IIRC there are on-line repositories that contain the results of such experiments resulting from a sort of SETI@home type project where people can use their spare processor time to run climate models (I'll see if I can find it again).

dvaytw at 01:06 AM on 14 November 2013Models are unreliable
I have a friend of a friend who is a physicist. He is ~not~ an AGW denier; he does however have objections to models as he claims they are used in climate science. He fears that, to quote him:
Where are the studies of model sensitivity to variations in the way any given model fixes up non-conservation of mass and/or energy? Every model I have looked at in detail has non-conservative processes, and they are always fixed up by hand at the end of each time step. This is a very bad thing. and I have yet to find any study on the sensitivity to the various choices one might make as to how to do this.
I suggested he post this question himself, but since he didn't feel it worth his time (which, I pointed out, is maybe why, though ignorant myself, I shouldn't take his objection too seriously), I told him I'd post it and see what people had to say. If this question doesn't explain his position clearly enough, I have some longer expositions of it I can post as well.

tlitb1 at 22:46 PM on 13 November 2013Deconstructing former Australian Prime Minister John Howard's 'gut feeling' on climate change
@BillyJoe
Google is your friend. Try "john howard religious zealots".
Thanks but I’m afraid Google isn't my constructor. I've tried Google and not found any examples of Howard literally describing scientists as "religious zealots".
In the above linked speech I *do* see he talks about
"...zealous advocates of action on global warming..."
"...public support for over-zealous action on global warming has passed."
But I have found nothing that remotely supports this statement:
Howard characterised scientists who accept the evidence that humans are disrupting climate as “religious zealots”.
This preceding statement implies it is derived from specific source statements emanating from Howard himself, not interpretations found in the media.
This piece is supposed to be "deconstructing Howard" not the media.
I think any reasonable person would think a more direct quote or reference can easily be offered up to justify the claim that Howard has described any scientists as “religious zealots".

Tom Curtis at 22:39 PM on 13 November 2013Deconstructing former Australian Prime Minister John Howard's 'gut feeling' on climate change
tlitb1 @1, I am not aware of John Howard calling climate scientists "religious zealots". In the lecture, he does say:
"I chose the lecture’s title ["One religion is enough"] largely in reaction to the sanctimonious tone employed by so many of those who advocate quite substantial, and costly, responses to what they see as irrefutable evidence that the world’s climate faces catastrophe, against people who do share their view. To them the cause has become a substitute religion."
He does not call anybody a "zealot" in the lecture, but refers to "public support for over-zealous action", and refers to "the more zealous advocates of action on global warming". Neither term implies directly that anybody are zealots as such. There is widespread reporting of the contents of the lecture as indicating that Howard had called the "climate change spruikers religious zealots" to quote a headline from The Australian. Note, however, that "religious zealots" does not appear in quotes, and so is not a direct quotation, but rather a paraphrase or interpretation of Howard's claims.
Absent evidence of a direct quotation, it appears that John Cook has mistakenly taken an indirect quotation to be a direct quotation. It is not clear whether he was original in doing so, or accepted, without due diligence, the mistake of another. In any event, the phrase "religious zealot" in the OP should not be in quotation marks.
Response:[John Cook] Howard does actually use the term zealot - but you have to watch the YouTube video of the speech where he opens with some off-the-cuff remarks. I've updated my blog post an excerpt of his exact words. Thanks for the comments, Tom.

tlitb1,
Google is your friend. Try "john howard religious zealots". Lots of links. This one explains his ignorance:
"Mr Howard revealed before the speech that the only book he had read on climate change was Lawson's An Appeal to Reason: a Cool Look at Global Warming, published in 2008.
Mr Howard said he read it twice, once when he was writing his autobiography, when he used it to counter advice for stronger action on climate change given to him by government departments when he had been prime minister."http://www.smh.com.au/federal-politics/political-news/the-claims-are-exaggerated-john-howard-rejects-predictions-of-global-warming-catastrophe-20131106-2wzza.html

Howard's remarks put me in mind of a saying of the great statistician and management consultant W.E. Deming.
"In God we trust; all others must bring data.“
Abbott and Howard (more like Abbott and Costello) are saying "Trust me; I know better than the data"

BillyJoe at 21:59 PM on 13 November 2013Deconstructing former Australian Prime Minister John Howard's 'gut feeling' on climate change
John Howard supported an emmissions trading scheme in 2006 for the following reason:
"... late in 2006 my Government hit a 'perfect storm' on the issue. Drought had lingered for several years in many parts of Eastern Australia, leading to severe restrictions on the daily use of water; not for the first or last time the bushfire season started early; the report by Sir Nicholas Stern hit the shelves, with the author himself visiting Australia, and lastly the former US Vice President Al Gore released his movie An Inconvenient Truth. To put it bluntly 'doing something' about global warming gathered strong political momentum in Australia"
He is now rejecting action on climate change for the following reason:
"In the past five years, the dynamic of the global warming debate has shifted away from exaggerated acceptance of the worst possible implications of what a majority of climate scientists tell us, towards a more balanced, and questioning approach"
In other words, political expediency.

Howard characterised scientists who accept the evidence that humans are disrupting climate as “religious zealots”. Consequently, he is not so convinced of the scientific evidence.
Could you show your source for where Howard specifically used the phrase "religious zealots" applied to scientists? I ask because it is not seen in the speech you link to.
On what does he base his views? Howard states that “…I instinctively feel that some of the claims are exaggerated.”
Also, could you show your source for this partial quote from Howard? It too is not included in the speech you link to.
Thanks.

dana@5,
You've got it opposite to me@2, therefore one of us must be wrong.
All of the credible resources, including our own graphic of Cloud Feedback point that you are wrong. The science of cloud feedback is not intuitive, so it's easy to get it wrong. Thhe best way to remember it is, as I pointed @2, by thinking of clouds as reflecting the sun in summer: low clouds (usually heavy and dark) "obstruct a lot of sun rays" therefore cool you down, especially in summer when the scorching sun may be unbearable. On the other hand, the high, very thin clouds (like jet contrails) have little influence on scorching summer sun. That's the main difference. Difference in IR absorbtion by low vs. high cloulds, although goes in the same direction of climate feedback, is not that signifficant.

Dana, thanks for an informative summary of recent work. Although there doesn't seem to be any contribution from cosmic rays to the secular trend of temperature, there does appear to be a correlation between CR and decadal temperature fluctuations. Of course, that correlation may just result from the correlation of CR with total solar irradiance (TSI). You could add Foster and Rahmstorf (Environ. Res. Lett. 6 (2011) 044022) to the evidence against a strong CR influence on temperature. They found that the amplitude of the TSI effect on temperature fluctuations since 1980 is no more than 0.05C. The TSI effect would implicitly include any CR effect. Since the sun is quieter now than it was in 1980, they found a small negative net solar effect from 1980 to 2011.

-
dana1981 at 01:26 AM on 13 November 2013Cosmic rays fall cosmically behind humans in explaining global warming
suckfish @1 - it depends on the type of cloud. As a general rule, low level clouds tend to have a net warming effect while high level clouds tend to have a cooling effect. Cosmic ray theory suggests more low level clouds would form.

One Planet Only Forever at 00:49 AM on 13 November 2013Free computer game - World at the Crossroads
Barry,
Why is there still any "desperate poverty" if the GDP has grown so many times quicker than the population?
Every nation has the wealth to ensure that none of its people are desperately poor. The most fortunate nations have excess ability that can easily assist less fortuante nations. And yet that simple and possible to do thing "does not happen", except in small grudging ways, or only if the more fortunate see a bigger personal payback.
The probable explanation is the way that callous selfish interest can become popular. Marketing of mass-consumption consumerism promotes the "bad attitude". A higher percentage among the poor are willing to do more to help other poor people. That is because the callous greedy ones have a competetive advantage leading them to be concentrated among the more fortunate. That competetive advantage can also result in the callous greedy ones having more political and international trade infuence. It is easier to appeal to self interest than generosity. Guilt can be used to get better bahaviour out of the less generous, but guilt is not a sustainable way to get someone to behave in a more caring and considerate manner. Also, guilt does not work on the "career callous pursuers of more for themselves".

"It is interesting to note that Global GDP has grown significantly faster than global population, yet there are still many people living in horrible poverty."
By all metrics that I know of, increased GDP has led to reductions in poverty. A notable example is China, which has achieved rapid growth over the last 30 years (arguably stimulated by fossil fuel development amongst other things), and steep reductions in poverty. At the same time, the gap between rich and poor has widened.
While a sizable fraction of the world's population still live in poverty, this fraction has decreased over the last 50 years. In the short term at least, accelerated productivity seems to have been a boon to the impoverished. The future under a changing climate is generally assessed as less optimistic.

chriskoz at 20:31 PM on 12 November 2013Cosmic rays fall cosmically behind humans in explaining global warming
suckfish@1,
Your assessment is simplistic and incorrect.
"clouds-keep-heat" (not just "at-night" but 24h) when they absorb ountgoing IR. Such property is attributed to high "Cirrus" clouds. Their effect is warming.
Other clouds, like low "Stratus" clould, do not a bsorb IR but they are very good at scattering the incoming solar radiation (with that respect they act as if they increased the Earth albedo), that's why the "look dark" from below. Their effect is cooling.
But on global average, the "cooling clouds win", i.e. stratus effect outweigh the effect cirrus effect. So, if the increased CR results in more cloud seeding, the net effect is cooling, assuming on average all types of clouds are seeded uniformely. I think that's the assumption of this article.
Of course, verious "sceptics" might argue only certain type of clouds (depending on their agenda) are seeded by CR, I don't know much about CR to comment on that. All I can say is: in the present trend, they seem to try reinforcing the fading "it's the sun" myth by pointing out that sun's energy variation has a positive feedback from CR. It seems now, that the feedback, even if positive, looks miniscule, unable to explain the Earth energy budget and its history.

Hi Lei@14.
The timeline covers over 200 years of history and the Vostok Core was extracted in the 1990s. As you can see in the project, space is constrained and when designing anything like this, information has to be edited in order to fit in with a design.
I have had many discussions with Skeptical Science contributers about what should and shouldn't be included, the reality is we all had different projects in our heads and this one is I guess the result of me leading it! If someone else had led it, the result would have been different.I take your point though. We have the Argo project in the timeline which is a project that provides data, so why not mention Vostok?
It's probably one for the to do list!
I'll point out that the project data is not 'static'. The data can be added to and in theory that is my intention. For example we did consider including the IPCC AR5 report, but I thought that because it is a 'history' project, AR5 isn't really history yet. It's to soon to include it and it can be added laterThe software is designed to automatically configure itself to new data, so that in the future it can be extended to as many years as is needed.

Re (3) of the hypothesis (fewer clouds will warm the earth) - is that true?What's the latest on the relationship between cloud cover changes and global temperature?I was under the impression that clouds-keep-heat-in-at-night and clouds-reflect-sunlight basically cancelled each other out? -
One Planet Only Forever at 14:19 PM on 12 November 2013Free computer game - World at the Crossroads
In my formative University years there was a program developed to simulate the development of a nation. The interface was a real-time responding dot-matrix text printer (pretty slick at the time).
Through trial and error, what could be seen was that rapid industrialization produced a higher GDP, but with horrible social costs. A much slower, smaller scale economic development of cottage-style collective activities (no investors just making money because they had money), took much longer to produce higher GDP but never produced the horrible social consequences of rapid industrialization.
It is interesting to note that Global GDP has grown significantly faster than global population, yet there are still many people living in horrible poverty.
Slow and steady, sustainable development is possible and is better, except for those who want as much as possible for themselves as soon as they can get it.
Short-term interests are not helpful. And the interest rate spike of the late 1970s played a significant factor in magnifying the focus on the short term. Unfortunately, the recent long stretch of low interets rates has not undone that tragic change of attitude. It seems that our currently popular socioeconomic delusion is not only producing damaging development, it is significantly influencing people to "more desperately want more for themselves as soon as possible", which feeds the pursuit of damaging unsustainable behaviours.
A more fully informed population is the answer, but that is not easy to achieve.
Part of the required solution is an end to the success of "partial information deceptive marketing". Full information marketing is seldom used because it is boring, more expensive, and would probably produce results that are contrary to the ineterests of the people with the money to develop and deliver it. Full information about climate change is never used by those trying to discredit the scientific findings. It is also never used by promoters of a hoped to be "Profitable Pursuit".
Another part of a sustainable better future for all is the lifestyle of the most fortunate being sustainable. If the most fortunate were not consuming non-renewable resources and were not over-consuming the renewable resources "everybody could develp to be more fortunate - for a very long time", no conflict, no unneccessary poverty.

Oh, and lets have some perspective on the relative drivers. The milankovitch forcing that drives ice age is due to change in forcing that is about -0.25W/m2 per hundred years at 65N. Globally, its maybe a tenth of that. By comparison, anthropogenic GHG is about 2.29W/m2 (from the latest AR5) over last 150 years on a GLOBAL scale. Given that 0.25 on one point of the planet is very much smaller than 2.29 averaged over entire globe, I think we stop worrying about ice ages.

Lei,
It is good that you have come here to try to learn more. In the 1970's there was extensive scientific discussion of the ice core data showing Ice ages every 100,000 years. The consensus (reached over 30 years ago) is that AGW has delayed the upcoming ice age at least 100,000 years and perhaps for much longer. The natural peak of the current interglacial was about 5,000 years ago. It then cooled until about 1900. For the past 100 years it has been warming faster than any other known period in the paleogeological record (see Mann's hocky stick for details of current warming). This warming is completely caused by humans and is the topic we discuss here on Skeptical Science. It is now warmer than at any time previously in the current interglacial.
If you have question about the problems likely to be caused by this un-natural warming, find a thread here and let her rip! You are welcome to ask how CO2 pollution has stopped ice ages if you wish.

PluviAL at 03:23 AM on 12 November 2013Greenhouse Gas Concentrations in Atmosphere Reach New Record
I too sigh with relief that the permafrost is not belching yet. The article repeats the common assertion that CO2 will remain high even if we stop CO2 augmentation immediately: It seems that natural consumption could increase substantially, especially with the help of civilization. Perhaps it is foolish, but our book, Pluvinergy … proposes that if we eliminate CO2 augmentation and increase uptake we can adjust the concentration back down within the century. Our hypothesis proposes working at the scale of the atmosphere to both eliminate CO2 augmenting fuels as well as directly cooling the planet. Thus, the theory proposes that we can have a chance of fixing the mess. Is our work that far off? I hope not.

CBDunkerson at 01:54 AM on 12 November 2013Extreme weather isn't caused by global warming
dvaytw, in my experience the fact that Lomborg wrote something is in and of itself a solid indicator that it is unlikely to be true.
More specifically on the IPCC, see this article on how the leaked draft of the impact report actually shows dire consequences indeed, rather than the low impact being falsely claimed by Lomborg and other climate fiction writers.
Unfortunately, I haven't seen a point by point rebuttal of that particular article. However, all his claims are all fairly generic denier talking points which have been debunked on this site and thus rebuttals can be found in the 'most used myths' or via the search box.
My suggestion would be to ask your 'skeptic' to quote the IPCC report itself saying that there is a scientific consensus that AGW is not increasing extreme events.... rather than Lomborg falsely making that claim. There is no such conclusion in the IPCC reports. It's fiction.
