That's true only if, by 'global temperature', you include geothermal energy (that's probably where your often repeated 'conservation of energy' non-sequitur came from). To his credit, even Al Gore doesn't take the argument to that level of absurdity (although it wouldn't surprise me if that was the Ace up his sleeve). In the context of the controversy of global warming (man's contribution to the causes of *atmospheric* warming), one must acknowledge that periods of increased volcanic activity and the resulting increase in atmospheric greenhouse gases - the likes of which would put our best efforts to pollute to shame - are neither the result of human activity, nor the result of atmospheric composition. Would you agree? And I'm confused as to why you dismiss increased solar output as a contributor to the observed increase in global temps. (Actually, I'm not confused by your dismissal, at all. I'm just trying to keep the discussion lively) Other factors forcing temperatures down, at the same time that an increase in Greenhouse gases is forcing it up, are well- established--see Global dimming. -- FF |

I'm just trying to keep the discussion lively) It is apparent that you came late to this discussion, and therefor do not understand some of what I say. There are two valid ways to inform yourself that are immediately obvious. The first, would be to review the thread. The other would be to ask me. That you eschew either method and instead chose the invalid approach of assuming I am a crackpot leads me to certainly conclusions about yourself that I prefer to not articulate in order to reduce the liveliness of the discussion. I use the addmitedly ill-defined term 'global temperature' in much the same way as everyone else, meaning some sort of ground level 'average' air temperature. I did refer to radioactive decay and tidal friction when pointing out the role of the conservation of energy, and lest you be confused, I did so only for the sake of completeness and do not contend that either plays a role in short-term climate change though either or both may have dominated long-term change at other times. Conservation of energy requires that the temperature of a body change whenever the energy absorbed by that body plus the energy generated within does not equal the energy emitted by it. Regarding the present effects of volcanism on climate change: http://volcano.und.edu/vwdocs/Gases/man.html "Present-day carbon dioxide (CO2) emissions from subaerial and submarine volcanoes are uncertain at the present time. Gerlach (1991) estimated a total global release of 3-4 x 10E12 mol/yr from volcanoes. T his is a conservative estimate. Man-made (anthropogenic) CO2 emissions overwhelm this estimate by at least 150 times." and, courtesy of the minions of the Bush administration who are routinely accused of 'suppressing' real science: http://www.osti.gov/energycitations/...sti_id=5271302 "Volcanic CO{sub 2} presently represents only 0.22% of anthropogenic emissions but may have contributed to significant greenhouse` effects at times in Earth history" Would you agree that volcanic eruptions in the distant past are non-sequitur as they have no effect on future short-term climate changes? I dismiss increased solar irradiance as a factor in the recent global warming on _Mars_ because solar irradiance has decreased over the three Martian years during which that temperature increase has been observed. Pleas try to maintain an awareness of what planet you are on. I've also noted that studies of variation in solar irradiance over more than one solar cycle establish an upper limit on any increase that corresponds to a a forcing of about 0.1 W/sqm, about one quarter of the forcing attributed to increasing CO2 over the same period of time. Other factors forcing temperatures down, at the same time that an increase in Greenhouse gases is forcing it up, are well- established--see Global dimming. FF |

If there were animals around then, was global warming caused by the animals doing too much farting and thus a rush of CO2 was released into the atmosphere and vola global warming began. Eighty percent of all CO2 that is released into the air today is caused by methane from livestock. This 80% figure may or may not be correct -- but surely you must acknowledge that while livestock flatulence is not the direct result of human activity, at least some of it certainly is an *indirect* result. I'm still trying to figure out how that methane contributes to the CO2 in the atmosphere. Does OP go about sparking cattle farts? Well, I'm a little puzzled by that too -- my best guess is that CO2 and methane are probably released simultaneously when a cow farts, and the OP is a little confused about the exact mechanism. Evidently methane in the atmosphere decomposes to CO2 and water. OP was just being succint. My point was that it's not accurate to regard livestock emissions as being unrelated to human activity -- surely there wouldn't be nearly as many bovines on the planet were it not for human agriculture. Yes it reminds me of a cartoon of someone who looked like Chief Dan George standing on a cliff i overlooking a herd of bison and saying to his young son, "Someday these buffalo will all be gone. The white man will replace them with cattle that will belch a lot and cause global warming." It's time to throw all their damned tea in the harbor again. The court case that prompted you to put that in your .sig was remarkable only in that the defendant was able to get his case to the USSC. The (ab)use of eminent domain to transfer property from one private party to another has been settled law for centuries. Being a liberal, I would have liked it if the BOR had always been interpreted so as to put an end to the practice on our side of the pond but I'm pretty sure it was never so. -- FF |

In article , D Smith wrote: Well, increased extremes in temperature and precipitation has been one of the predictions. I heard that being said back in the 1970s. Horsepuckey. Back in the 1970s, the 'panic du jour' was global COOLING. And global cooling has been happening too. Otherwise there would have been a much greater temperature rise over the last 40 years. As it is, the warming effect have been negating the cooling effect and may soon win out. The particulates responsible for global cooling (actually for global dimming that in turn causes global cooling) have a much shorter lifetime in the atmosphere than do green house gases. http://www.environmentaldefense.org/...5338&linkid=mp When were we first alerted to global warming? The study of global warming and the greenhouse effect goes back more than 180 years. But, the international scientific consensus pointing to humans as a major cause of global warming was affirmed in 1985 when a body leading environment and climate scientists formally recommended a treaty to address global warming. The concept of the earth's atmosphere acting as a heat trap was first proposed by French mathematician and physicist Joseph Fourier in 1824, during the early years of the Industrial Revolution. In 1896, Swedish chemist Svante August Arrhenius, one of the founders of the science of physical chemistry, first put forward the idea that more carbon dioxide in the atmosphere from human activities could raise the earth's temperature. Six decades later, in 1957, American geophysicist Roger Revelle coauthored a paper with Hans Seuss finding that much of the carbon dioxide pollution emitted to the atmosphere was not absorbed by the oceans as some scientists had argued - leaving more in the atmosphere, which would eventually warm the earth. At about the same time, Charles Keeling set up a long-term carbon dioxide monitoring site in Mauna Loa, Hawaii. It first documented the slow but inexorable rise in atmospheric carbon dioxide concentrations in response to the emissions from burning fossil fuels and tropical forests. [I first saw the Mauna Loa data cited to predict global warming in the early 1970s--Natural History magazine I think, FF] Then, in 1985, a conference sponsored by the United Nations Environment Program (UNEP), the World Meteorological Organization (WMO), and the International Council of Scientific Unions forged a consensus scientific view warning that some future warming was inevitable due to past emissions. The conference recommended consideration of an international treaty to address global warming. See also: http://discovermagazine.com/2006/feb/global-cooling/ http://www.wmconnolley.org.uk/sci/iceage/ I presume you are not confusing these issue with 'nuclear winter', though wouldn't be so generous with some others. I do remember a movie or two and some other touchy-feely stuff predicting another ice age. -- FF |

Nonsense, absolute and utter nonsense. If Kyoto were about reducing CO2 emissions, it would have placed restrictions on India and China as well. In order to keep the pool clean, you have to stop _everyone_ from peeing in it. OK, if that's so -- then why does Kyoto allow China and India to keep peeing in the pool? Like I said -- political basis, not scientific. How much would Kyoto allow a Chinese to pee in the pool and how much would it allow an American? Got any numbers? |

This does not in any way speak to whether or not GW is a real problem or not. But, Kyoto is a political cesspool, nothing more. country or subset of countries can find a complete solution in isolation. In order to keep the pool clean, you have to stop _everyone_ from peeing in it. Then why does Kyoto punish the people who are barely in the pool and who never pee in it while requiring little or nothing from those using the pool as their outhouse? Kyoto doesn't punish anybody. A quarter of the pee in the pool comes from North America. -- FF |

The point is that Kyoto places *no* restrictions on China and India, and *does* place restrictions on the western industrial democracies. Why is that? Is CO2 emitted by China somehow less harmful than CO2 emitted by the United States? There is a lot less of it. That looks to change in a couple of decades at most. -- FF |

All the more reason why they should be under the same restrictions as the western industrial democracies. But they're not. Neither is India. Neither are we. I agree that they should be. But it is worthwhile to note that if they were under exactly the same restrictions, they could STILL continue to increase their emissions without violating those restrictions. It would be like imposing a speed limit of 55 mph for bulldozers, same as for cars. Kyoto is at bottom a politically-motivated attempt to gut the economies of the western industrial democracies. Do you have any evidence to support that nonsense? -- FF |

Neither is India. Neither are we. Yes, but that's only because we haven't signed and ratified it. If we had, we would be. Yes. We'd be restricted to releasing no more than several times the CO2 emitted by China and India combined, though 5.2% less than we did in 2000. Objecting to that is rather like objecting that a 55 mph speed limit for automobiles is unfair when there is no speed limit for bulldozers. [snip] Kyoto is at bottom a politically-motivated attempt to gut the economies of the western industrial democracies. Do you have any evidence to support that nonsense? I just *gave* you the evidence: Kyoto exempts India, China, and other developing nations from the CO2 restrictions that it imposes on western industrial democracies. Not *my* fault you're willfully blind. The evidence supports the idea that the motivation for the treaty is EXACTLY what the treaty states. That makes sense, even if the world is wrong on the science. Your idea requires that the Western Democracies who did sign on to Kyoto to have agree to gut their own economies for no particular reason at all. Does THAT make sense? -- FF |
