What are the generally accepted estimates of total C02 going into the air from industrial activites? What are the generally accepted estimates of total other non-water anthropogenic GHG going into the air? (Im deliberately leaving out water for right now, but I will reintroduce it) |

so far we have not really proved that human activity contributes to climate change, but neither have we disproved it, either. in any case, i think the environmentalists would do better focusing on aspects of human activity that DO have a very direct, measurable change in the environment, such as air/water pollution. why vilify CO2 when far more deadly carcinogenic chemicals heighten incidences of asthma and cancer? i think what humans CAN do is find mutually beneficial activities that both promote environmentalism and free-market principles. for example, raising efficiency makes energy production (among other things) cleaner, but also raises the bottom line. developing cleaner and lighter jet engine frames certainly reduces CO2 emissions (among other things, and for whatever that's worth) but also allows for fuel savings (and that's worth a lot). what i do disagree with are the idiots, for example, who stand outside heathrow protesting air travel.

Looking closely at the energy transfer and energy balance estimates. Finally, I did a lot of work looking at net GHG flux, the isotropic signatures of that flux, and the basic physics behind CO2 and other GHG reemission characteristics. Next, I investigated the claims in the contra- camp relating to H2o heat retention and the relationship of H2O in the energy cycle.
Finally I looked at closely at the energy transfer and energy balance estimates. What I also found interesting were how many claims that the skeptics (and I, at one time) used, were not necessarily indicative of the the entire mechanism. Truthful in whole, yet obfuscating in use. And, quite frankly, the recent satellite data showing prototypical warming of the atmosphere as it is predicted to occur in a CO2 and other GHG warming manner was eye-opening. Finally, most of the recent studies involving solar irradiance convinced me that while the sun could be responsible for portions, (see the Osanski study above which is being used as evidence of "sun only", where the authors state that that cannot be the case, or the Lockwood study that just came out), there is not nearly enough energy irradiance in the solar record to hold accountable all the warming effects we see here. I said earlier: Quote:

Finally, I realized that the "water is a greenhouse gas" argument, while true, is not indicative of the true nature of the problem. Water vapor is a feedback mechanism, not a forcing. Further the H2O is greenhouse gas argument overlooks some very basic mechanics of the CO2 forcing effect. And, as I indicated, the warming signature is very much in line with what one would expect with AGHG effects. I will readily admit that all these items are not "perfect", nothing in science ever is. But the items were enough to overcome my "it can't in any way shape or form be AGHG", and further it overcame my "we don't know enough about it to call it" level. |

In a scientific talk, I will expect you to back general statements up. If those are presented in a respectful way, they will be shown a respectful response. And when you call someone else's facts, evidence, studies, and/or data "puffheaded numbers", expect your more generalized statements and incorrect items to be treated with the corresponding amount of respect that your "puffheaded numbers" statement shows (which is none, by the way.) And when you make the statement of "Your scientific number crunching sounds pretty persuasive only for those not thinking", I will treat any mistake or generalization even more harshly, since again, that shows a fairly significant lack of respect. And further, when you basically accuse me of using numbers to lie (which is what you are doing above), I will definitely show lapses in a reasoning process in a very harsh manner. So before you get all bent out of shape over my tone to you, please consider your tone to me on your initial reponse, which was fairly disrespectful and (quite honestly) downright rude. So if you want my respect in comments to you sickle, I would expect at least the same from you. So, sickle, do you wish to start over on a clean slate here? |

Pari: I mentioned the IPCC report. There has been 3 reports released. The
4th will not be released until November of this year, but I read the summary of the highlights of it last night. Further, I have read the previous 3. Now, all of your arguments are taking all of you in circles until you establish a few ground rules as to facts and figures. First, what each of you have to establish is what reports are acceptable to you. There are some conclusions of researchers that have been proven politically motivated as well as bank-rolled. This is also mentioned in the IPCC reports. A variance of past, present, as well as future models were used in each report. Facts were ascertained in each report based upon each model. HOWEVER, the results, and what caused them, can not be proven 100%. I stipulate, in my opinion, that the earth is warming, since facts have proven such. However, the CAUSATION, is the main question to be answered. Does the warming coincide with the 100 year cycle, concluding a natural occurrence......or, is it warmng at a more rapid rate, and deviating from the 100-year cycle? I'm particularly interested in the stratosphere findings. |

1. Observe some aspect of the universe. 2. Invent a tentative description, called a hypothesis, that is consistent with what you have observed. 3. Use the hypothesis to make predictions. 4. Test those predictions by experiments or further observations and modify the hypothesis in the light of your results. 5. Repeat steps 3 and 4 until there are no discrepancies between theory and experiment and/or observation. So where in there is the part where the guy who has the new theory about anthro GW can ignore counters about orbital mechanics and the Sun's radiance unless the people asking use Tanqy-approved methods?

What causes the huge amount of CO2 on Venus?
Quote:
Do you belong to the 'Flat Earth Society'? If the Sun increase its radiance by 25% what would the Earths temperature be and why? You get it? Don't complicate the obvious and expect us all to take a radical change because you would perfer Al Gore as Emperor of socialist America. When the obvious out weighs unproved headiness and pomp I will choose the obvious because as history has shown science is not always right. And living by pop-science can cause death. Inter Diet and nutritional science for one. Forrestry for another. IVAN

A summary of global conditions
Global Warming Fast Facts
I would like to throw in a question which never comes up in discussions on global warming. We know that the earth's atmosphere is not heated directly by the sun, but rather by the earth via longwave radition, conduction and latent heat from evaporating water which are all the product of solar radiation. But we also have at the core of the earth molten rock. Assuming that molten rock contributes to the heating of the surface of the earth and hence the atmosphere, and assuming that such heat reaches the surface faster in some regions of the earth's surface than in others due to the varying material consistency of the earth between the molten zone and the earth's surface--here is my question--could removal of large underground seas of oil from the earth cause more heat to escape from the earth's core in the form of increased longwave radiation? Now jumping ahead: If the absense of former oil deposits causes the earth to pump out more heat these days, more than the sun's radiation accounts for, then can we say the the earth is cooling more rapidly than usual? And if it is cooling faster, won't a point be reached when its heat LOSS begins to decrease, thereby lowering its contribution to atmospheric warming? Perhaps current global warming is the prelude to global cooling, solving one problem for man and creating another, namely an new ice age. burrr. ![]()

I could some choice nouns and adjectives for that behavior. I choose not to use them based on respect and potentially making a gross over-generalization. I mean I have already been taken to task for referring to critics of AGW (i.e. those who do not think that AGW is a viable theory) as a "naysayer." Based on your last two ad-hom laced posts, I was stupid for apologizing for that action. Quote:
The interesting thing about this concept is that solar flux into the system is the important concept in the energy balance equations, not the combined effects of "everything that has happened centuries ago". The important solar readings are the ones not from "over the last few centuries" but the ones from the time of the increased excess energy. The current ones do not show any high readings in the time during the energy buildup, and in the skeptic's best case in the recent studies, at most solar irradiance accounts for only 20-30% of the increases.

Too bad most of the "proofs" I have seen here are limited to one phrase utterances of "Mars attacks" and "the sun". But, when someone has the temerity to state an opposing thesis, you spout "prove it". No offense Dale, but that is hypocritical as all h*ll. Quote:
Par actually has, by posting on online correlation study by Ahlbeck (not peer reviewed, though) Quote:
6. state the hypothesis 7. allow others to replicate 8. others should be able to state a cogent reason *why* the author's reasoning is not correct. But, this step 8 is also step 2, where the critic is now the person who has the onus to prove their counter. That is when you utter a single phrase answer of "mars is warming" utterly fails. Quote:
Quote:
Funny thing there is precious little evidence of global warming on Mars. You seemingly want to jsut gloss over that fact.... well to be precise, that lack of facts. Finally, since you are so convinced that Mars is warming due to solar irradiance, find me unequivocal data that ties the solar mechanism to that warming. Dale, what I am saying is that you do the same steps that you demand of others. Or, don't. If you fail to do that, your "its the sun" or "its the Mars warming" assertions are as specious as you call the "correlators" in the AGW debate. Or did you fail to realize that? You want Pluto? Okay, lets look at the what I see as the available data from Pluto. The "only" evidence on termperature on Pluto is a difference in Pluto's atmospheric thickness, inferred from two occultation observations 14 years apart. (sarcasm mode on)Yah..... that nails it..... (sarcasm mode off) If you have any more, please feel to add. But, all I think at this point the only thing one will get from you is your pithy "Mars is warming", "its the sun", followed by your demand for proof from anyone else who has the temerity to state anything else.... or perhaps I will be called a horse's a$$ for bothering to look at the vaunted "studies of Pluto" ------------- If you want to have a discussion on the science, that's great. If you want to disaprage talk about the science and evidence on the same as ""drip(ping) snot ... from lofty heights", well that is your right as well. And if you want to devolve your talk on science into one line pithy proofs, while demanding much more from others, I find that hypocritical. And I would find that fairly humorous coming from someone who seemed to excel and demand that others do that one time...... (but apparently not now.) On a side note, I hope your modeling hobby is doing well for you. |

A desert that is almost unbearably hot by day can actually be very cold at night. The only exception I have found was in Aden (now South Yemen) where the lowest recorded temperature during my 13 month tour was 93 degrees Fahrenheit. (The highest daytime temperature was 154 degrees in the Wadi Tyme!)
