Not ad hom. See Tusenfem's post. Your quote from Schneider is pretty much the theme of my "rant": "Each of us has to decide what the right balance is between being effective and being honest." What I have done in many of my posts in this thread is exhibit the use of rhetorical techniques that maximise effectiveness at too much cost in honesty. I am an economist, not a climate scientist, but it is not necessary for me to be an expert in climate science to spot these rhetorical devices. I have also pointed out some abuse of statistics, where I have some expertise. Complete honesty without effectiveness is the material of dry scientific papers. The IPCC is not expected to be at the "no effectiveness" end of the scale, and most of us do not wish to address material of no effectiveness. In the case of the misappropriation of Keenlyside et al (2008) to make points that the authors say it does not support, who's being effective and who's being honest? For honesty, I will own up to the rhetorical device of anecdotalism in that comment. |

I genuinely do want to keep this civil and friendly, so I'll put my cards on the table too, so you can recognise me as a reasonably intelligent human being and hopefully treat me as such. I come from an engineering background in fluid mechanics and systems. I have studied the science around climatology in some depth over the last few years. I also have formal training in examining and evaluating data, hypotheses and theories, and understanding the way individual scientists and institutions work, which I gained in a degree course in the history and philosophy of science. With regard to your concerns about co2: An extra 30% of naff all on top of naff all is still naff all. In any case, a doubling of co2 would warm the earth by at most 1C (IPCC figure), unless the apparent negative feedback nixes even that. The water vapour feedback the AGW theory relies on for the extra warming Schneider and his colleagues try to scare us with isn't happening. The reduction in outgoing radiation predicted by greenhouse computer games isn't happening. The mythical 'extra heat in the pipeline' can't happen because it doesn't make it past logic 101. It's a falsified hypothesis being endlessly modified against each new piece of contrary real world empirical evidence in a desperate ad hoc fashion. Bad Science. ![]() If someone tried to present AGW as a new ATM theory they would get a justifiably good grilling from Tusenfem and others. Back it up with $80,000,000 and a compliant disaster story hungry press however, and who knows where it will end. |

How is that post not political, again?
I thought you were screaming "ad hom" when someone pointed out the politics in your post, and now... more politics.

If there is room for skepticism in the AGW debate, it is A) the extent to which feedbacks amplify CO2 forcing, and B) whether the time constant of ocean thermal inertia is really long enough for significant "heat in the pipeline".Though my background is engineering, I've spent a lot of time reading papers on both subjects, and it is clear that zero or negative net forcing is statistically impossible--and anything under 1C is not very likely. It is also clear that for the high end predictions (anything over 3C) to be correct, the ocean thermal inertia time constant has to be huge--long enough that we have only seen half or less of the forcing of current CO2 levels so far. That is the part I'm skeptical about (I won't re-hash my previous posts). I'm comfortable with the low end of the IPCC report's range of 2C-4.5C--which doesn't put me in the ATM camp, but puts me squarely outside the alarmist camp (2C is bad enough, but probably not the end of the world).

As I said, 1C is the IPCC's figure. I know the physics, and it might be 1C all else being equal, but it never is. The climate system is such that if one parameter changes, all the others do something too, both because they were busy changing anyway, but also in response. We just don't know enough about how the Earth might compensate for an increase in one atmospheric gas. What we do know is that the earth has maintained itself within liveable limits in a bi-polar sort of way for a very long time. Not much sign of feedbacks disastrously amplifying anything so far. Lots of indications that the earth tends to equilibrium within limits. There is heat in the pipeline, but it's solar heat and nothing to do with co2. Solar radiation penetrates the ocean to depths of a couple of hundred feet and gives its energy up. Back radiation from the atmosphere can't penetrate the ocean surface further then it's own wavelength. It concentrates a lot of energy there and causes prompt evaporation. The ocean has an equilibrium level with respect to solar input of energy at which it neither gains nor loses heat-energy. Solar activity was well above that level for most of the C20th from around 1915 on to a peak around 1960 and another in the late 80's. The ocean heat content has been rising since we started measuring it in the late 50's, until 2003 when it started to level out and fall again. So the cooling ocean will keep the land and atmosphere warm for a while yet, but unless solar cycle 24 get's it's act together, things will start to get a lot colder in a year or so from now. Just like 200 years ago, the last time the sun did a similar funk on us. Volcanos and earthquakes are statistically more likely when solar activity is low too. There are lots of things to worry about besides co2, if you are the worrying type. The evidence suggests the Earth was around 0.6C warmer than now about 1000 years ago. then it got pretty cold from around 1300-1740, then it has warmed back up since, and seems to be topping out about now. Pardon me for not panicking. Last edited by Stroller; 17-November-2009 at 10:03 PM.. |

Also, since you apparently believe that adding a tiny amount of something to a tiny amount of something should have no effect, perhaps you wouldn't mind increasing the dioxin level in your body to ~1 part per billion. That's a very small amount: much, much, much smaller than the amount of CO2 in the atmosphere. By your logic, it shouldn't have any effect at all, right? Quote:

I've repeatedly linked to Oreskes' paper showing the consensus in the peer reviewed literature. You described Oreskes 2004 as "... past her propagandize by date." That's extremely insulting, blatantly false and does nothing to refute the fact of the consensus. You said "... an increasingly large proportion of scientists question the attribution of that increase in temperature to increased co2." Well then, where are they publishing? If your claim is true, repeating Oreskes' study should find a large fraction of peer reviewed articles that dispute the consensus view. Where are they?

http://www.populartechnology.net/200...upporting.html Plenty for you and Gillian to get your teeth into there. Note well that I do not necessarily agree with or endorse all the views or hypotheses expressed in all these papers. Just as there are many pro AGW papers which don't agree with each other either. Science isn't neat, coherent, or cut and dried. A lot of these were written since 2004. Like I said, Oreskes 2004 is past it's propagandize by date. If you thought that statement was scandalous, you should consider whether I was talking about her paper, or your misuse of it. Five years is a long time in science. Quote:

When you say something, anything at all, on climate it would be a very effective method of discrediting it, regardless of its merits, simply to point out that you stand by this claim.

In addition to parejkoj's thorough response, couple of things about carbon dioxide's effect of the climate of the Earth:
- We have measured its absortion properties in laboratories - We have measured the same properties from atmosphere - We have measured how the outgoing longwave radiation decreases in carbon dioxide absorption band as expected theoretically - We have measured how the downward longwave radiation increases accordingly, that is, we have measured how atmosphere emits more heat back to the surface. We even have measured it happening in the spectral band of carbon dioxide. - We have measured that the water vapor feedback is positive, in other words it is amplifying the carbon dioxide induced global warming, just as expected theoretically. - Cloud feedback has been unclear due to lack of measurements with enough quality but latest research shows that also cloud feedback is positive (Clement et al., 2009). As Lindzen was advertised once again despite all the flaws in the latest work, here's some papers that show how Lindzen's iris hypothesis doesn't work in real world.

Hi Ari,
I'm always open to the science, so I will work my way through your links and air my thoughts on the papers. ETA I see most of the links are from your own blog. Excellent, I'll answer you there. Last edited by Stroller; 18-November-2009 at 10:29 PM.. |

One thing that I have to say about Deniers: They will always, without exception, applaud any argument that even looks like it supports their argument.
This is just another case in point. I have yet to be proven wrong.

![]() One of the interesting things about the Mishchenko result is that it agrees with the calculations I did on ocean heat retention between 1993-2003 where I identified a 4W/m^2 forcing which had caused the rise in steric sea level over the period. Of course, no-one here was interested in the calculations when I posted them on this thread. Probably because they didn't involve reference to the gas which warmists are addicted to.

Stroller, stop this immediately! You seemed to be on the nice track lately. SolusLupus, don't feed the frenzy, that does not help in any way. Apparently, this thread is going for a train wrack again, maybe soon we will have to put in a cooling down time on this topic, of say ... 50 years.

No, the discussion is here so answers are also expected here. Besides, lot of the evidence I gave have already been presented here many times, and some of it you already have given the "I take a look at it" sidebrush before.

Also, a request:
Can people please avoid PMing me over this discussion? I'm not interested. If you can't say it in public, don't bother at all.

Meanwhile, in climate science (what this thread and forum should be about):
Two interesting papers have been posted to arXiv today: ACRIM-gap and total solar irradiance revisited: Is there a secular trend between 1986 and 1996? - Krivova et al. (2009) Abstract: "A gap in the total solar irradiance (TSI) measurements between ACRIM-1 and ACRIM-2 led to the ongoing debate on the presence or not of a secular trend between the minima preceding cycles 22 (in 1986) and 23 (1996). It was recently proposed to use the SATIRE model of solar irradiance variations to bridge this gap. When doing this, it is important to use the appropriate SATIRE-based reconstruction, which we do here, employing a reconstruction based on magnetograms. The accuracy of this model on months to years timescales is significantly higher than that of a model developed for long-term reconstructions used by the ACRIM team for such an analysis. The constructed `mixed' ACRIM - SATIRE composite shows no increase in the TSI from 1986 to 1996, in contrast to the ACRIM TSI composite." The Greenhouse Effect Does Exist! - Ebel (2009) Abstract: "In particular, without the greenhouse effect, essential features of the atmospheric temperature profile as a function of height cannot be described, i.e., the existence of the tropopause above which we see an almost isothermal temperature curve, whereas beneath it the temperature curve is nearly adiabatic. The relationship between the greenhouse effect and observed temperature curve is explained and the paper by Gerlich and Tscheuschner [arXiv:0707.1161] critically analyzed. Gerlich and Tscheuschner called for this discussion in their paper."

I think a good analogy for what we will see out of this is the Truthers who pick through the news footage for “discrepancies” in the official story. It’s really pretty easy to pick though incomplete informal communication for things that “seem” to contradict the end result.
The nature of pre-publish work is uncertainty, questions, opinion and speculation. This process as a whole lead to a clear picture at the end but this isn’t true though the entire process so there will always be an abundance of details that don’t seem to fit the final conclusion if you look at them out of context. The realclimate link above details just such out of context quotes being misused already. |

Theories make predictions. A theory that cannot explain observations is incorrect in some aspect.
Observations require an explanation. As the planet has stopped warming there must either be some unknown mechanism that is cooling the planet (as CO2 continues to increase however the planet's temperature has not changed when corrected for El Niño and La Niña) or the late twentieth warming was due to a different mechanism than increases in CO2 AWG. Also interesting is the recent abrupt unexplained simultaneous stoppage of Greenland Ice sheet surges into the Atlantic. As noted there is past evidence during the cyclic "Heinrich Events" of concurrent abrupt solar minimums, by the late Gerald Bond. Comment: There is no explanation of what caused the original ice sheet surge or why the ice sheet surge has abruptly stopped. Also interesting is evidence the increase in the ocean level has also abruptly stopped. What is observed during a "Heinrick event" is a surge in ice flow into the Atlantic from multiple unconnected ice sheets followed by a roughly 500 year to 1000 year abrupt cooling period. Specifically what causes a Heinrich event is not know, however, there are multiple suggested mechanisms. http://www.spiegel.de/international/...662092,00.html Quote:
