Heat Definition: The energy transferred from one body or system to another as a result of a difference in temperature. The energy in the body or system before or after transfer is sometimes erroneously called heat and that usage should be avoided as it leads to confusion. That is one definition. Symbols and equations would be a better way of expressing yourself. O.K. Now you have made your point. It is another 'dictionary diversion'. It's called mathematical precision and theoretical consistency. You could have made this simple revision of the literature back at the beginning, and don't tell me to read the references. Until you make a point there is no incentive to verify it. The point I made, was that you are not keeping abreast of modern scientific advances and developments. You are not using scientific methods in the problem solving process, that is, you are not participating in the production of scientific results and solutions. Learning and relearning should be a never ending process. I offered a solution to your particular problem in the form of links, which you declined to examine. Guys, guys. Thomas is obviously refering to the version of the second law that no useful work can be extracted from a system where there is only a single heat reservoir. However, I do not think that this means that temperature is what is important, not heat energy. josh halpern However, there is also heat energy and that was obviously the way the term was being used. I am afraid that I have to convict you of being deliberately obscure. Yes, I admit it was another pathetic attempt to get you to read and do research, and solve practical problems, like the fundamental human problems of global warming, global pollution, species extinction and warfare, driven by hydrocarbon combustion, heat engines, and the resultant overpopulation and resource exhaustion. The problems are extremely challenging and difficult, but they are not insoluble, if you accept that challenge, and participate in their resolution.

Thus, it follows that global warming has an effect on weather. ;-) It was pathetic, but hardly an attempt to educate. That would require presenting your objection in a more rational and direct fashion related to the issue at hand. As in links to precisely defined mathematical symbols and equations. As long as you maintain the confusion between the engineering term of heat and the 'heat energy' under discussion, nobody is going to follow your logic. Perhaps then they can follow the links and read the mathematics. Thomas Lee Elifritz http://elifritz.members.atlantic.net |

It was pathetic, but hardly an attempt to educate. That would require presenting your objection in a more rational and direct fashion related to the issue at hand.

As long as you maintain the confusion between the engineering term of heat and the 'heat energy' under discussion, nobody is going to follow your logic. Perhaps then they can follow the links and read the mathematics. Why? Do you have a new point to introduce? The last one is pretty well defined as 'not even wrong' but irrelevant to the point raised.

In the global weather system there are NEVER uniform levels of heat, because there are three primary shear forces exerted on the atmosphere by planet rotation, there is polar and equator insolation differences, there is season tilt., there are irrgularities of surface features, there are irregularities in oceanic topography, there are different albedos of surfaces. Even current levels of CO@ have effects and it is paramount to be monitoring these effects to build the database crucial to accurate predictions of the future. You have been a denialist, and a "uniformist", and you have been visibly wrong. |

Fine, but that was not the point. The point was a technical one about a statement that was wrong *in and of itself*.

You have been a denialist, and a "uniformist", and you have been visibly wrong. No. The problem now becomes, not whether a uniform temperature can be converted to mechanical energy (winds, currents, etc ) but whether global warming ( a change in the average temperature) will have an effect on the levels of heat differences. It is not a simple question. |

Fine, but that was not the point. The point was a technical one about a statement that was wrong *in and of itself*. You statement is consistent with your body of statements. You believe in uniformitism in global warming, and you are disputatious about evidence that focallized hot spots are being aggravated TODAY by increases of greenhouse gases. Since you have a posting history, track record, reputation, you are interpreted to mean your normal position advanced regularly and frequently. YOU put words in your mouth, and you are held responsible for consistent self-inflicted blindness that causes you to keep repeating them. If evidence has alterred your position -- say so, and you will be held accountable to a new (instead of the old) position. Even current levels of CO2 have effects and it is paramount to be monitoring these effects to build the database crucial to accurate predictions of the future. You have been a denialist, and a "uniformist", and you have been visibly wrong. No. The problem now becomes, not whether a uniform temperature can be converted to mechanical energy (winds, currents, etc ) but whether global warming ( a change in the average temperature) will have an effect on the levels of heat differences.

Yeah, like *China* is breakin' is hind-end to sign Kyoto. Where did I mention Kyoto? I don't support it. Being out of touch with reality means recognizing that global warming is going to be a problem requiring real action with solutions that work. Because I don't think that the Kyoto Protocol is a solution that would work, I don't support it. (However, I do support the UN Framework Treaty on Climate Change.) The Kyoto treaty is still nice to have in place until something better has been worked out, flawed as it is. If you look at all the complaints against the treaty you will find that they are quite contradictory and these contradictions are going to plague any further treaties too. My focus has always been on how Kyoto is phrased; it expects countries to make self-sacrificing moves that are not in their national interest. It seems to me already obvious that the signees can't live up to their commitments, and I really doubt that most of them want to try. Thus, I think that their ratification provides a convenient excuse for not really doing anything, in the line of "Look, we signed the Kyoto Protocol, we must be serious about climate change -- nevermind that our fossil fuel consumption is still increasing and we aren't hitting our targets. And let's bash the United States for being realistic while we're at it." For a treaty like this to work, it's got to be designed to cater to national interests. Like a scorecard. A country gets points awarded for each program it implements, for each reduction it achieves, for each unit of hybrid vehicles that its citizens drive. The points translate into real things: discounted prices on the world market for vital commodities might be an example. Or contracts with other countries for specific business objectives. You trade success on pollution and energy consevation for something else. I don't know China's status regarding the Kyoto Protocol, since they were specifically exempted, along with India. I would have expected that they'd ratify it for that reason. Good guess. China ratified the Kyoto treaty 30/08/02 http://unfccc.int/resource/kpstats.pdf It was a good guess. I couldn't imagine China not signing something that favored their interests like that. ------------------------------------ SwimJim (formerly James G.

Kyoto is about setting up a framework, just as the Montreal Protocols were originally. I don't think the Kyoto Protocol's framework is workable. I'm going to say this in a couple of posts, but there isn't a reward system that does something for countries that hit their reduction targets. They just promise to try, and current results indicate that isn't doing much. Give them incentives and they might try a lot harder.

Because I don't think that the Kyoto Protocol is a solution that would work, I don't support it. (However, I do support the UN Framework Treaty on Climate Change.) Playing Devil's Advocate for a minute, if we can't get something relatively minor like Kyoto agreed on how do you propose we arrive at a solution that will work that everyone is happy with? We're getting to the point where we need to start running, but we haven't even figured out how to walk yet. Well Dave, you ask an excellent question. Not being an international diplomat, I don't think that I can offer you a superb answer. My basic point is this: whether or not Kyoto is agreed to, it probably won't work. And even if it was implemented to its fullest extent, it wouldn't have much of an impact on the problem. Therefore, I think that too much time and effort and money has been expended in trying to achieve an idealistic "agreement" that will be paid nothing more than lip service. Meanwhile, coral reefs are disappearing. In order for something like this to work, there have to be economic incentives. Countries would sign in a minute (even the U.S.) if there was a perceivable and achievable economic gain. Al Gore, bless his misguided heart, wrote in "Earth in the Balance" that if costs to the environment could be quantified, very quickly the "balance sheet" of current economic development and growth would be drastically altered. So, what I would propose, speaking in generalities because specifics are always hard to come by, is this: a treaty that quantifies the environment economically. For example, how much is the fresh water from melting glaciers worth? How much will a given economy suffer if that fresh water supply diminishes by 25% over the next 50 years? If a country takes steps to reduce greenhouse gas emissions, can you reward them with fresh water "credits" -- perhaps some tugs will pull an Antarctic iceberg up to Oman and provide fresh water to the Arab states. Another example is soot control. Both India and China still release tremendous amounts of soot, which causes health problems and is also an element of climate change. So REWARD them for steps they take to reduce soot -- let the WHO give them increased child health care services in return for hitting soot reduction targets. (And I full admit I borrowed this particular idea.) Technological "first world" nations should be rewarded for developing new energy technologies and exporting them cheaply to developing nations that need them. This would reduce emissions and improve the enviroment in those countries. Anybody reading this newsgroup who's familiar with me may find it surprising that I don't support the Kyoto Protocol. Well, let me put it in simple terms: while I admire the beauty and grandeur of Mt. Rushmore, I don't support it. It besmirched the natural environment, cost a lot, and it makes a grandiose statement of United States nationalism. In essence, it's a useless symbol. And that's what I think of the Kyoto Protocol. I admire the effort and the aims, but not the result. Until we get realistic about what works -- what SELLS in the international marketplace -- nothing useful will be achieved.
