There's been a lot of discussion lately about rules and definitions. The following is a cut and paste from a variety of sources that I compiled and arranged for my own use. The more I compiled the more I thought it might be useful to post here as a sort of guideline. I welcome the opportunity to refine it and, hopefully turn it in to a durable resource for this board at large. First some simple definitions of science taken from dictionary.com: - a branch of knowledge or study dealing with a body of facts or truths systematically arranged and showing the operation of general laws: - - the mathematical sciences. - - systematic knowledge of the physical or material world gained through observation and experimentation. - any of the branches of natural or physical science. - systematized knowledge in general. - knowledge, as of facts or principles; knowledge gained by systematic study. - a particular branch of knowledge. Science is a discipline that collects and organizes knowledge in the form of testable explanations and predictions. The earliest efforts of science were purposeful attempts made to provide explanations of events in the physical world based on known causes. Science is based on research. This is an iterative process which led to the development of the scientific method. It is required for knowledge creation and seeks to objectively explain the events of nature in a reproducible way. Scientific research is used in support the scientific method and can be labeled as either basic or applied research. Basic research is the search for knowledge and applied research is the search for solutions to practical problems using knowledge. An explanatory thought experiment or hypothesis is put forward as explanation using principles and are expected to seek consilience – fitting well with other accepted facts related to the phenomena. Modern science is divided into three major branches that consist of the natural sciences (e.g., biology, chemistry, and physics), social sciences (e.g., economics, psychology, and sociology), and formal sciences (logic, mathematics, and theoretical computer science), which study abstract concepts. Formal sciences do not rely on empirical evidence and are therefore not considered to be science in some circles. Disciplines that use existing scientific knowledge for practical purposes, such as engineering and medicine, are described as applied sciences. Climate would also be an applied science. What we are looking for in the science of weather or global temperatures is physical in nature. The primary source, empirical evidence is information acquired by observation or experimentation, in the form of recorded data, which may be the subject of analysis. Empirical evidence is the information received by means of the senses, particularly by observation and documentation of patterns and behavior through experimentation. Empirical evidence is information that verifies the truth (which accurately corresponds to reality) or falsity (inaccuracy) of a claim. In the empiricist view, one can claim to have knowledge only when based on empirical evidence. In science, empirical evidence is required for a hypothesis to gain acceptance in the scientific community. This validation is achieved by the scientific method of forming a hypothesis, experimental design, peer review, reproduction of results, conference presentation, and journal publication. This stands in contrast to the rationalist view under which reason or reflection alone is considered evidence for the truth or falsity of some propositions. Early in the 19th century, John Dalton suggested the modern atomic theory, based on Democritus's original idea of indivisible particles called atoms. The laws of conservation of energy, conservation of momentum and conservation of mass suggested a highly stable universe where there could be little loss of resources. The understanding that all forms of energy as defined in physics were not equally useful as they did not have the same energy quality led to the development of the laws of thermodynamics, in which the free energy of the universe is seen as constantly declining: the entropy of a closed universe increases over time. Beginning in 1900, Max Planck, Albert Einstein, Niels Bohr and others developed quantum theories to explain various anomalous experimental results, by introducing discrete energy levels. Quantum mechanics shows that the laws of motion did not hold on small scales. Einstein's theory of relativity and the development of quantum mechanics led to the replacement of classical mechanics with a new physics which contains two parts that describe different types of events in nature. Classical physics, the description of physics existing before the formulation of the theory of relativity and of quantum mechanics, describes nature at ordinary (macroscopic) scale. Most theories in classical physics can be derived from quantum mechanics as an approximation valid at large scale. Quantum mechanics differs from classical physics in that energy, momentum, angular momentum, and other quantities of a bound system are restricted to discrete values (quantization), objects have characteristics of both particles and waves (wave-particle duality), and there are limits to how accurately the value of a physical quantity can be predicted prior to its measurement, given a complete set of initial conditions (the uncertainty principle). Quantum mechanics gradually arose from theories to explain observations which could not be reconciled with classical physics, such as Max Planck's solution in 1900 to the black-body radiation problem, and from the correspondence between energy and frequency in Albert Einstein's 1905 paper which explained the photoelectric effect. Early quantum theory was profoundly re-conceived in the mid-1920s by Erwin Schrödinger, Werner Heisenberg, Max Born and others. The modern theory is formulated in various specially developed mathematical formalisms. In one of them, a mathematical function, the wave function, provides information about the probability amplitude of energy, momentum, and other physical properties of a particle. Planck's hypothesis that energy is radiated and absorbed in discrete "quanta" (or energy packets) precisely matched the observed patterns of black-body radiation. Planck corrected Wien's law model using Boltzmann's statistical interpretation of thermodynamics and proposed what is now called Planck's law, which led to the development of quantum mechanics. Einstein further developed this idea to show that an electromagnetic wave such as light could also be described as a particle, or quanta (later called the photon), with a discrete quantum of energy that was dependent on its frequency. Quantum mechanics describes the behaviors of atoms during chemical bonding and the flow of electrons. Quantum mechanics is essential to understanding the behavior of systems at atomic length scales and smaller. Quantum mechanics was initially developed to provide a better explanation and description of the atom, especially the differences in the spectra of light emitted by different isotopes of the same chemical element, as well as subatomic particles. In short, the quantum-mechanical atomic model has succeeded spectacularly in the realm where classical mechanics and electromagnetism falter. You learn something new every day if you are lucky! |

1. A great deal of what I have posted above I had read here before. I just didn't have the proper background to work within. 2. Climate science should be an applied science. I can forgive them if they are trading on old science. 3. Climate science only exists in the rationalists' view which only requires reason or reflection. 4. Climate science is failing because the underlying natural science does not support it. 5. There is no empirical evidence that supports climate change. 6. It's time to put green house gas and effect to bed as it is used today. I would call upon physicists to update the theoretical foundation of the heat effect of carbon dioxide in the atmosphere. 7. There is no testable prediction in climate science. The phenomena they are relying upon is not reproducible. 8. Classical mechanics is subordinate to new physics of quantum mechanics. 9. References to Boltzmann's statistical interpretation of thermodynamics is superior to classical mechanics and must be observed. 10. Classical mechanics and electromagnetism fail to explain light and chemical bonding. 11. I need to know quantum mechanics relied upon for the atomic behavior of chemical bonding and the flow of electrons. Chew me up. You learn something new every day if you are lucky! |

Let's apply this rationale to Chritianity and see how it sounds: "The science of the human soul should be an applied science. I can forgive Christians if they are trading on old science." That sounds just as silly. Harry C wrote: 3. Climate science only exists in the rationalists' view which only requires reason or reflection. There is no reason or rational basis for a religious belief. Harry C wrote: 4. Climate science is failing because the underlying natural science does not support it. No religion has ever had science supporting it. It would cease to be a religion if there were. Climate Science is still a religion and as such, is not "failing" per se. Harry C wrote: 5. There is no empirical evidence that supports climate change. Nor can there ever be. No one has ever unambiguously defined the "global climate." No one has been able to figure out how to gather data on the completely undefined. Harry C wrote: 6. It's time to put green house gas and effect to bed as it is used today. I would call upon physicists to update the theoretical foundation of the heat effect of carbon dioxide in the atmosphere. There is no update required. Chemistry already gives us an accurate understanding of the physical properties of CO2 and thermodynamics tells us that it cannot create additional energy. Harry C wrote: 7. There is no testable prediction in climate science. The phenomena they are relying upon is not reproducible. There are plenty of Doom&Gloom predictions, of earth-bake and of rising sea levels, that the ocean will turn into caustic chemicals, that humans will be baked into zombie-like refugees, etc ... What you must specify is that there are no predictions that are specifically derived from a falsifiable Climate Change model. There are none of those. Harry C wrote: 8. Classical mechanics is subordinate to new physics of quantum mechanics. STOP! You are egregiously in error. Quantum mechanics is not physics. Quantum mechanics is a branch of mathematics ... specifically statistical math word problems concerning nature. Quantum mechanics is not science because it makes no predictions; it renders only probabilities and distributions. If you throw two dice at the craps table, physics will tell you how the dice will bounce around given a felt surface, the initial height of the throw, the mass and material of the dice themselves, etc... Quantum mechanics will tell you the probability the roll will result in a two, the probability of a three, of a four, etc..., i.e. math, except that all the word problems involve photons or protons or electrons or other elements of the quantum world. Quantum mechanics doesn't predict what will happen because it cannot. Heisenberg made sure of that. The uncertainty principle must be factored into the calculation of probabilities, i.e. the more you know about momentum the less you know about position ... and vice-versa. Bottom line, quantum mechanics is just math word problems, e.g. "a stream of photons pass through a double-slit front screen in which two five-inch vertical slits are spaced three inches apart. How will the photons be distributed on the back screen. Show your work." Harry C wrote: 9. References to Boltzmann's statistical interpretation of thermodynamics is superior to classical mechanics and must be observed. Absolutely false. Boltzmann used classical physics ... to predict nature. Where he could not, because it was too complex a system, he used statistical math to establish probabilities and distributions. Harry C wrote:10. Classical mechanics and electromagnetism fail to explain light and chemical bonding. False. If you have ever purchased chemical consumer products like soap, window cleaner, etc... then you can be pretty confident that chemistry has a pretty good grasp on chemical bonding. If you are using a computer with a microprocessor and a motherboard, or have ever seen a traffic signal, you can rest assured that physics has electromagnetism under control. If it can be engineered then classical physics has it covered. . I don't think i can [define it].

tmiddles wrote: Let me start with the easier 2 of 3. As to the empirical evidence on temperature data and reliability I wrote in another thread: How many data collection points would it take to have a high probability global average temperature? Part of the problem with the current temperature data sets, besides being corrupted by reporting agencies, is that it not only requires the temperature at the surface but at elevation intervals that can track changes in temperatures as it moves around the globe and throughout the atmosphere. I can only venture a guess that the temperature would have to be measured to a point in space where it does not vary based upon what happens on earth. I received this answer from IBdM which is on the mark: That depends on the target margin of error. I'm sure you have noticed that no one ever discusses this but it is an absolute requirement at the very beginning of any discussion of this type. I understand your previously stated GW theory as surface and 2 meters above. My own thought was that there is so much temperature variability in the atmosphere, how do you know that the temperature change isn't just moving around in the atmosphere. So, my thought was that you have to have temperature measurements from the surface up to the limit of CO2 range in the atmosphere or the native temperature of space. I'm not sure what your mane by "contradicts the theory". temps falling at times as CO2 increases. I believe the 'alarmists' view is that there is a direct correlation between increased CO2 and temperatures. This has not been proven. I think it's generally acknowledged and can find the charts to demonstrate it if needed. I've got to do some work to create my answer to number 1.

I am on the same page with you that the easiest box to check here is that we cannot claim to be detecting +/- 0.25 C annual changes. I'd go with Pat Franks on that one: Earth surface temperature measurements I would say that as IBD has presented it we wouldn't know summer from winter, which are often just 10C apart (a 30+ degree margin of error is way too high) but this is not work I know how to do myself. As for 3, In general I think accepting the premise for an argument temporarily is worthwhile. By the data claimed CO2 has spiked and temps have not. This is what I meant by "contradicts the theory". However the theory is that CO2 levels have a delayed effect CO2 Takes Just 10 Years to Reach Planet's Peak Heat, some estimates were 40 years It does "sound right" to me that it would take years for a change in atmosphere to be reflected in ground temp.

I don't know the answer but want to believe that CO2 cannot increase temperatures. I understand many of the peripheral arguments that support that position. However, there are enough things I'm not comfortable with that leaves me searching. The first thing I wanted to do was understand what the alarmists believed was CO2s action in the atmosphere to create heat. I had already deduced that it must have been assumed to amplify heat. I cannot find anywhere that demonstrates the a mass balance equation of the energy that hits a CO2 molecule. But in the other direction I cannot find anyone else that takes the position that CO2 cannot increase heat in the atmosphere. The non-alarmists or skeptics that I read allow for minor increases in temperature from increased CO2. It would appear so easy if leading physicists could agree on the effect of CO2 in the atmosphere. But that's not the case. That begs two questions of both ITN and IBdM. 1. Which scientists influenced your beliefs about the effect of CO2 in the atmosphere? 2. Did you create your position or were you influenced by someone else? I want to see a nail driven in the coffin of AGW/CC in the worst way. But I suspect there is a missing piece to the argument that there is NO change in temperature based upon CO2 in the atmosphere. I will accept that there is an insignificant change in temperature based upon increased CO2 in the atmosphere. I'm still working on my own mass balance illustration to synthesize what I think is happening. I felt like I got a curve ball in my thoughts when I started reading about quantum mechanics.

I just saw your post above this one and will wait for ITN/IBD to weigh in.Harry C wrote:...there is no positive correlation in the change in reported CO2 levels and reported global temperatures.... Not correlating to my mind would mean no increase or a decline in temperature. To reiterate all of this is pretending we can detect minute changes of 0.25C which neither of us buy: The temperature shown by NASA/GISS does sown temp increasing from 1960 to 2020 by about 1.2C.  CO2 measurements show that CO2 increased in that time frame:  Which makes sense since fossil fuel CO2 emissions blew up around then:  So my thoughts pro and con are: Pro- The dramatic increase in fossil fuel Co2 emissions, Co2 ppm measurements, and the forecast that those factors will grow even more dramatically going forward, seems reliable to me. I can see how this is scary on it's face. It freaks me out. Con- Using the same sources temp data we can see that temps have risen and fallen before the last 60 year period. It's not like it was level and smooth and suddenly temps changed. More questionable is looking at US temperature which is arguably more well documented than many other parts of the world:  Without question (even disbelieving the ability to accurately meassure temperature) the US saw a heat wave in the 1930s. This would have had nothing to do with CO2 because it wasn't elevated then. So the question I see is IF CO2 played a roll in pushing the temp up the last 60 years then from what? Was the temp going to rise for other reasons anyway? Was it going to fall and we've really seen a boost? I've yet to see that question addressed. This was talked about (here)  Basically if someone "knows what's going on" they should be able to state what temperatures would be doing without CO2s influence. A bit on the PRO side it is fair to say that AGW theory is based pretty exclusively on fossil fuel use and that has only very recently increased dramatically. So the lack of historical data on massive fossil fuel use is just a reality. We can wait and see, jump the gun, be proactive, let the good times roll, panic for no reason, but it's not the fault of anyone analyzing this that this is a "new one". Edited on 06-02-2020 04:08 |

Harry, I figured out your confusion. You don't understand the crucial difference between "heat," "temperature" and "thermal energy." You have been throwing those words around as though they are interchangeable. They are not. Look: Harry C wrote: This is the whole reason I came to this forum. I don't know the answer but want to believe that CO2 cannot increase temperatures. ... then you pivot ... Harry C wrote: But in the other direction I cannot find anyone else that takes the position that CO2 cannot increase heat in the atmosphere. Increasing heat has no bearing on increasing temperature; it's the other way around, i.e. increased temperature increases heat. Thermal energy is energy. It gives matter temperature. Temperature cannot increase without additional (thermal) energy. Heat, on the other hand, is a FLOW of thermal energy, from higher temperature to lower temperature. A lake and a river both have a lot of water but only the river has a FLOW, from higher elevation to lower elevation, and no water in the river is actually the flow of the river. You can increase the flow of water by reducing restriction, e.g. change to a wider pipe. You can increase the flow of thermal energy (heat) via conduction by reducing restriction, e.g. by swapping in a material with a greater heat coefficient. This however will not cause the average temperature of the system to change because no additional thermal energy is added ... and none can be "created." If you empty a lake into a river by opening the flood gates of the dam, you clearly have increased the flow of the water, but you haven't increased the amount of water. .

IBdaMann wrote:This is a well described definition that is not disputed anywhere I'm aware of. I'd add that the greater the temperature difference between two objects the greater the heat. So there is more heat between two plates that are 10C and 40C then there is between two plates 200C and 205C. Though the second set of plates has a higher temperature the heat between them is only from 5C difference in temp. "Hot" and "Heat" are not equivalent concepts. You will "turn the heat on" in your house in most cases to achieve a thermal equilibrium with your environment and in effect reduce the heat or flow of thermal energy out of your body. Where there is dispute is that ITN/IBD do not believe in Flow being a "Net Flow" as I do, when it comes to radiance.

No. Planet earth's temperature remains unaffected. The room might certainly increase in temperature.

tmiddles wrote: what I meant was not the air temperture in the room but the temperature of the entire contents of the room: air + computer + furniture .... This is moderately complicated. Thermal energy cannot be contained or "stored" so everything in the room will increase in temperature, perhaps negligibly, as the thermal energy from the CPU "dissipates" into the room and then out of the room. So yes, the earth's molten core does ultimately radiate out into space, it's just that the earth's crust greatly restricts that flow of thermal energy to the surface (the substances of the earth's crust have very low radiativities and very low conduction coefficients) ... and there are miles of crust. This results in a negligible flow and we treat it as zero. It is not actually zero but we treat it as such. When there is a volcanic eruption, the amount of thermal energy reaching the surface is so small (relatively) that the rest of the planet remains completely unaffected (temperature wise) as that thermal energy quickly radiates off into space. Back to the CPU, its thermal energy will act like soot and find its way into everything ... just not necessarily in quantities of substance. However, the reason I mentioned the server racks previously is that when the central heating shuts down in a building in the dead of winter, the server rack room becomes really popular. In there the walls, the air, the people ... everything has a warmer temperature. . I don't think i can [define it].

Energy from a nuclear reactor gets pretty well contained for a while. Some of them use H2O for the containment. Some nuclear energy waste gets contained for a long time. That's a lot of energy. |

For that to be true there must be correlation. CO2 increases would indicate a commensurate increase in temperature at some point lagging the CO2 increase.

ITN, Not that i'm an expert on nuclear reactors but i can see that you aren't. In some reactors water is used to shield from radiation and from thermal energy transfer. I gave it as an example of "insulation" that works really well, sort of like greenhouse gasses. The difference between containment and shielding is not difficult to understand. Your fixation on semantics isn't so easy to understand. It seems to me that it is just a lot of smoke and mirrors. Edited on 06-02-2020 21:50 |

keepit wrote: Not used for either in any reactor. Water is coolant in reactors. The nuclear reaction generates thermal energy, which heats the water, which conveys that thermal energy a heat exchanger to a secondary loop, which carries that thermal energy to turbines, which convert it to mechanical energy, then to electrical energy. All reactors on board navy ships operate this way and all nuclear power plants operate this way. Water is not used for shielding in any part of the reactor or it's primary loop. ...deleted Mantras 33...22...10...(containment<->shielding)...17... Shielding blocks neutrons by absorbing them. Containments block nuclear material from getting out into the environment. They are built to withstand steam should a reactor leak it's primary coolant into the containment area. The primary loop never leaves the containment building. Water is used in storage ponds for spent nuclear fuel. It keeps the rods cool and absorbs the stray neutrons from them (it's a heated pool! ). Only in this instance is water used as a shielding. The Parrot Killer Debunked in my sig. - tmiddles Google keeps track of paranoid talk and i'm not on their list.

ITN, I got my info on reactors from Wiki. And you're missing the main point as usual and that is that energy is and can be contained, at least temporarily. You continue to misapply the the 2nd law. The "insulation" in reactors is an analogy to greenhouse gasses. |

So I think we can set aside the birth of the planet as being a unique situation : ), so looking at the mesozoic on what explanation is there for changing CO2 levels not correlating with temp? AGE OF THE DINOSAURS  I believe where the two meet in the mesozoic is when they think an steroid hit us. Now that chart was posted here: https://wattsupwiththat.com/2013/06/04/dr-vincent-gray-on-historical-carbon-dioxide-levels/ Who concludes "Increase of Carbon Dioxide is thus wholly beneficial to "the environment" There is no evidence that it causes harm." And here: http://www.biocab.org/carbon_dioxide_geological_timescale.html So I found this counter argument (not my own work):  https://skepticalscience.com/co2-higher-in-past-intermediate.htm It's rebutting: ""The killer proof that CO2 does not drive climate...Jurassic-Cretaceous periods...4000 ppmv...should have been runaway greenhouse..." And no I'm not done I plan to post a real argument once I've gone through that article but wanted to share the links in advance. Edited on 07-02-2020 01:56 |
