^^^ "Chaos Theory: Also referred to as non-linear dynamics, chaos theory is a mathematical concept explaining that it is possible to get random results from normal equations. The main precept behind this theory is the underlying notion of small occurrences significantly affecting the outcomes of seemingly unrelated events.
Chaos theory has been applied to many different things, from predicting weather patterns [emphasis added] to the stock market. Simply put, chaos theory is an attempt to see and understand the underlying order of complex systems that may appear to be without order at first glance" (Dictionary.com).
^^ My point is that so-called experts and even actual experts in any field can be wrong. And I never said that "we should completely give up on" anything, as you put it. I said, "I'm just asking people to think critically, to not just accept the spoon-fed 'news' and the whims du jour of the mainstream media and special interest groups concerning global warming." In addition, I did not say that global warming--if it is caused or worsened by humans--and any other real threats should be mutually exclusive. Decisions must be made to apply scarce resources to those short- and long-term problems that actually exist and can actually be remedied by humans. 10/15/2006 3:12:57 AM |

^ From the BBC link:
"The simulations of present climate and past changes will be used to test different versions of the model, and the most realistic will be used to predict the century's climate.
Dr Myles Allen, of the University of Oxford, said: 'Thanks to chaos theory we can't predict which versions of the model will be any good without running these simulations, and there are far too many for us to run them ourselves.
Together, participants' results will give us an overall picture of how much human influence has contributed to recent climate change, and of the range of possible changes in the future.'
David Stainforth, the experiment's chief scientist, said: 'While many model studies in the past have made plausible predictions of climate change, it hasn't been possible to quantify our confidence in these predictions.'"
From the Columbia University link:
"[Edward] Lorenz, M.I.T. Professor Emeritus of Meteorology, opened the 1997-98 International Research Institute for Climate Prediction (IRI) lecture series on Sept. 30 with 'How Well Can We Predict Climate Change?' in the Shapiro Center for Engineering and Physical Sciences. He has been studying irregularities in the atmospheric energy cycle at M.I.T. since 1948, and his research in dynamic atmospheric systems led to his development of the chaos theory and his 1993 book, The Essence of Chaos.
He defined chaos as 'a system that has two states that look the same on separate occasions, but can develop into states that are noticeably different.' In an example of a non-chaotic system, he referred to a golf ball dropped twice from the same height above a fixed point. The golf ball, he said, will fall to the same point both times. He distinguished this from a very different system illustrated by the meandering path of the sheet of paper.
Weather forecasting, like the fall of a golf ball, has short-range accurate predictability. Lorenz asked, 'Can we then continue weather forecasting to reach desired climate prediction?' The audience waited. 'It's not that simple," he said, 'because climatic systems are inherently chaotic.'"
By the way, sarijoul, I own you now. Can you give me the standard deviation on that? Step off.

because someone is applying chaos theory to a system doesn't make it chaotic. you don't know what you're talking about.
in turbulence modelling we have these things called time-averaged equations.
they're averaging states that we can't exactly predict 100% accurately, but over a decent time period the prediction can be quite good. these same sorts of models can be applied to large systems (like the planet).
just because it's not simple doesn't mean that it's unpredictable and scientists and engineers are getting further along in being able to do this. 10/15/2006 3:56:57 AM |

the point is: we can't necessarily predict a specific day in the future's weather. we are getting to a point where we might be able to predict the average temperature over a number of years 100 years in the future.
this is of course reliant on assuming some things like human intervention into the system.
but the point of these predictions isn't to know the exact one day or even one year, but more to know the reactions of different stimuli to the system. the science is fairly solid in that regard. a lot of the challenge is simply in scale and complexity. this does not make the system chaotic in itself. it just makes it complex. but not so complex that it is outside of our grasp to get useful results with a feasible level of complexity in the near future. 10/15/2006 4:27:05 AM |

climate is not chaotic (weather prediction over a short period of time otoh is chaotic for all intents and purposes). climate is affected by far fewer (relatively) variables, such that we should be able to handle in the coming years. if you really want to get down to it everything is chaotic. but what use does the term have at that point.
this argument has basically become one of semantics.

Climate modelling is, as of my last check, still bunk.

An interesting and legit argument. I was thinking the same thing the other day. If you look at the past 50 years, since the "global warming" myth came into existance, you can see that there has been a general trend in fluctuating hurricane seasons. Katrina was an anomale, obviously, as was Hazel, Andrew, Carmen, so on and soforth. There is no proof that they are increasing, and this season shows this. 10/15/2006 3:54:51 PM |

i've thought that the hurricane argument on either side is pretty much a red herring. hurricanes are uncommon enough and unpredictable enough that not much can be said for the limited data set that we have. average temperature on the whole is an entirely different story. we have plenty of data regarding global and localized weather trends. 10/15/2006 4:05:53 PM |

^ First, I'll address your latter "point," as it were. I was smart enough to quote a person who does understand chaos theory. Here it is again for the ill-informed:
From the Columbia University link:
"[Edward] Lorenz, M.I.T. Professor Emeritus of Meteorology, opened the 1997-98 International Research Institute for Climate Prediction (IRI) lecture series on Sept. 30 with 'How Well Can We Predict Climate Change?' in the Shapiro Center for Engineering and Physical Sciences. He has been studying irregularities in the atmospheric energy cycle at M.I.T. since 1948, and his research in dynamic atmospheric systems led to his development of the chaos theory and his 1993 book, The Essence of Chaos.
He defined chaos as 'a system that has two states that look the same on separate occasions, but can develop into states that are noticeably different.' In an example of a non-chaotic system, he referred to a golf ball dropped twice from the same height above a fixed point. The golf ball, he said, will fall to the same point both times. He distinguished this from a very different system illustrated by the meandering path of the sheet of paper.
Weather forecasting, like the fall of a golf ball, has short-range accurate predictability. Lorenz asked, 'Can we then continue weather forecasting to reach desired climate [emphasis added] prediction?' The audience waited. 'It's not that simple," he said, 'because climatic systems are inherently chaotic [emphasis added].'"
Second, concerning your former drivel, I never claimed to be a statistician. As to my cartooning or my understanding thereof or what have you, I am the recipient of a North Carolina Press Association award for journalistic illustration, which was presented to me by then-Governor Hunt, for my work, among other honors. If I were you, I wouldn't be so down on a so-called cartoon understanding of things--people with such an understanding win Pulitzers every year.

Of course we should, this is not at issue. The question is what you intend to do about it. If you want to increase the federal gasoline tax from 18 cents to 20 cents, go right ahead. If you want to slap a $1 per ton tax on coal go right ahead.
But if it is your intention to raise the gasoline tax from $0.18 to $4.00 then we will fight you tooth and nail. To inflict that much harm upon the American people you had better have strong evidence that not doing so with cause far greater harm, which is in dispute. Climate modeling is uncertain, so even if Climate modeling predicts an apocalyptic future, which it doesn't, you must discount it in accordance with its certainty, which is small, and then again with the probability of arrest, which is also small, and then discount the future value.
Hence why some researchers conclude more good can be done for mankind by expending our energy fighting corruption and alleviating poverty.10/16/2006 11:14:42 AM |

L.F. Richardson:
Quote : | "Big whirls have little whirls That feed on their velocity, And little whirls have lesser whirls And so on to viscosity." |
Point 1 - On global warming Some people act like hurricanes are the only evidence for global warming, and that one year tells the whole story. There are icecore samples, direct correlations between Co2 and temperature, shrinking icecaps, etc. No one can dispute the increasing amounts of Co2 that we are adding to the atmosphere. The questions seem to be impact, and expense.
Point 2 - On Chaos theory 101 I don't think that many nonscientists understand chaos theory -although they like to throw it around. An example of chaos conditions: When you incrementally turn up the temperature on a pot of water, linear convection occurs. At some point though, when you turn the temp up a just a little more the pot goes into a mad boil. You've passed a boundry into a nonlinear state where that small change had huge effects.
Chaos occurs in instances of time, until the energy in the system goes back below the boundry level and things move back to a relatively linear state. Chaos is a series of instanious occurences. If you measure weather over time (climate?) then you are averaging the effects of instantaneous chaotic events. Averages over long periods of time are, by definition, are not chaos.
I, by the way, do believe that global warming is a reality. And I don't think the real costs to make improvements would be as high as the naysayers would have you believe.

The fact that termperature increases correlate with increases in CO2 is not in dispute.
You should find something that is in dispute to argue ... like whether it's man's fault, or whether that is the cause of the temperature rise, or whether the whole thing is just nature's cycle ... or whether it would cost too much to do anything about it, etc ...

^x9 Damn cogent argument, BoBo. I'm inclined to believe that our planet MAY be warming.
My main point of dispute is the incessant need of some to blame global warming--if it is in fact happening--only on or primarily on humans. Even if we all magically agreed tomorrow that humans are responsible for the warming in question, what could we actually do about it? We do have the ability to affect weather in a minor way, but we certainly cannot exert long-term control over the climate of the world. To think we could is sheer arrogance!
And concerning chaos theory, of course I don't fully understand it. I never claimed that I did. I simply quoted the man who literally wrote the book on chaos theory and he apparently claims that it has a correlation to climate prediction. Hell, I often quote Poe; yet, I am not a master of trochaic meter, either.
Again, predicting a giant system that may be affected by variables as obscure as cow farts and the flap of butterfly wings and many others over a period of decades is inexact, to say the least. Therefore, I find the certainty about global warming that some espouse to be maddening.
