Here's my answer to your questions:...Hard test. Here's my answer to your questions:<br /><br />1) a. heat rises<br /><br />2) b., no, atm is not a greenhouse<br /><br />3) d. none of the above, Venus is not not hot because of greenhouse effect or what Carl Sagan said: it is likely hot because of electric circuit (plasma) coming from the sun.<br /><br />4) a. Rise, an IR lamp increases the temp.<br /><br />5) a. Heat always flows from hot to cool as per 2nd law of thermodynamics.<br /><br />6) b. No, entropy can only increase without work input; the natural state of the universe.<br /><br />7) a. 0.09C object can only heat another to same temp without heat input.<br /><br />9) b. increase as per Stefan-B output.<br /><br />10) a. definitely by limiting convection. "Greenhouse effect" in atmosphere does not exist.<br /><br />11) Greenhouse effect requires decrease of entropy in defiance of corollary of 2nd law of thermos.<br /><br />12) b. applies only to solid bodies, not atmosphere.<br /><br />13) a. hard to say. Pressure not mechanism for 33C warming via pressure law as you claim.<br /><br />14) b. Totally false, Jupiter is twice expected heat output of EMR input from the sun. Self-generated heat, nothing to do with gas pressure laws, but from unknown and previously unrecognized heat source. I think it's free energy generation via homopolar generator free energy effect. Present physics too limited to recognise.<br /><br />15) b. decrease due to increased heat-to-atmosphere energy sink effect.<br /><br />16) b. Dry lapse rate is shallower, hence putting lie to so-called "greenhouse effect". Anthony Watts to stupid to realise.<br /><br />17) Neither a nor b. Greenhouse effect responsible for no greenhouse warming, since greenhouse effect doesn't exist.<br /><br />18) c., since, again, no atm greenhouse effect<br /><br />19) We don't know enough to say. It's not b. as you claim. I say electric circuit from sun most likely.<br /><br />20) We don't know. I think 33C warming is due to a) electric circuit from the sun; or b) homopolar free energy generation (based on my work with DePalma and free energy generation of N-machine) of earth's supposed liquid metal core.<br /><br />21) It's a violation of what convention physics knows at present, but we don't know why...yet._https://www.blogger.com/profile/02172141732539373669noreply@blogger.comtag:blogger.com,1999:blog-4142988674703954802.post-84477350300055258042014-02-25T14:04:26.806-08:002014-02-25T14:04:26.806-08:00Robert Austin says:

And again we see a dense atmosphere, not greenhouse gases, responsible for the relatively high 320K temperature at this altitude.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4142988674703954802.post-88548945538498043902014-02-23T12:17:34.367-08:002014-02-23T12:17:34.367-08:00Related posts from Claes Johnson:

Rather, it reduces the steeper gravitationally-induced thermal profile so that it meets the surface at a lower temperature where the wet adiabatic lapse rate prevails.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4142988674703954802.post-36079659876316736362014-02-18T16:10:15.414-08:002014-02-18T16:10:15.414-08:00http://wattsupwiththat.com/2014/02/17/crises-in-cl...http://wattsupwiththat.com/2014/02/17/crises-in-climatology/#comment-1570611<br /><br />Alex Hamilton says:<br />February 17, 2014 at 3:19 pm<br />Donald C. Morton<br /><br />I dispute your statement “There is no controversy about the basic physics that adding CO2 to our atmosphere absorbs solar energy resulting in a little extra warming on top of the dominant effect of water vapor.”<br />There is absolutely no empirical evidence that increasing the percentage of water vapor above any particular location leads to warmer mean temperatures. In fact a statistically significant study has shown the opposite to be the case and dry deserts do in fact have warmer mean temperatures than rain forests at equivalent altitudes and latitudes, as intuition tells us.<br />From what do you suppose water vapour is raising the temperature? Are you really going to try to tell me that an isothermal troposphere (all at 255K) is a state of thermodynamic equilibrium with maximum entropy and no unbalanced energy potentials, when clearly the molecules at higher altitudes would have greater total energy because of the extra gravitational potential energy? Where Sir is your understanding of the Second Law of Thermodynamics?<br /><br />The planet Uranus provides all the evidence we need that it does not require water vapour or carbon dioxide to raise temperatures at lower altitudes in a planet’s troposphere. As you can read in Wikipedia (Uranus | Troposphere) that troposphere is about 320K at its base, despite a radiating temperature of less than 60K. So it’s not “33 degrees of warming” out there, nearly 30 times further from the Sun: it’s 250 degrees of warming due to a gravitationally-induced thermal gradient that is seen in the whole of the 350Km high troposphere. And in case you think the methane is doing the trick, it’s all concentrated in the uppermost layers where it absorbs virtually all of the solar energy and radiates it back to space. There is no convincing evidence of internal energy generation, no significant energy imbalance at the top of the atmosphere, no significant direct solar radiation reaching down into the troposphere and no surface at the base of that troposphere to absorb any radiation. Yet it’s hotter than Earth there.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4142988674703954802.post-85657905217255720762014-02-17T09:54:23.006-08:002014-02-17T09:54:23.006-08:00http://hockeyschtick.blogspot.com/2013/11/new-pape...http://hockeyschtick.blogspot.com/2013/11/new-paper-shows-simple-basic-physics-of.htmlMShttps://www.blogger.com/profile/06714540297202434542noreply@blogger.comtag:blogger.com,1999:blog-4142988674703954802.post-92026441289143940152014-02-13T17:18:36.484-08:002014-02-13T17:18:36.484-08:00Konrad says:

Tropospheric convective circulation is not a constant flow. Due to the diurnal cycle, the breakaway of airmasses from the surface boundry layer stutters. Each dawn the Reyligh number for airmasses must be exceeded before they rise.<br /><br />All that doubling CO2 can do is cause breakaway to occur a few seconds earlier in the day and slightly speed up tropospheric convective circulation and the non-radiative transport of energy from the surface.<br /><br />Increased radiative gases will also cause more powerful subsidence of airmasses from altitude due to increased OLR to space.<br /><br />When their critical role in tropospheric convective circulation is taken into account it can be seen that radiative gases net effect is cooling at all concentrations above 0.0ppm.<br /><br />http://wattsupwiththat.com/2014/02/13/103183/#comment-1567063Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4142988674703954802.post-703535578701868502014-02-13T17:12:33.758-08:002014-02-13T17:12:33.758-08:00http://wattsupwiththat.com/2014/02/13/assessment-o...http://wattsupwiththat.com/2014/02/13/assessment-of-equilibrium-climate-sensitivity-and-catastrophic-global-warming-potential-based-on-the-historical-data-record/#comment-1567147<br /><br />Alex Hamilton says:<br />February 13, 2014 at 4:53 pm<br />I suppose some may doubt in my comment at 3:13pm that carbon dioxide acts in the same way as moisture in the air in reducing the lapse rate and thus reducing the greater surface warming resulting from the thermal gradient (dry lapse rate) which evolves spontaneously simply because it is the state of greatest entropy that can be accessed in the gravitational field.<br /><br />Many think, as climatologists teach their climatology students, that the release of latent heat is what reduces the lapse rate over the whole troposphere.<br /><br />Well it’s not the primary cause of any overall effect on the lapse rate. That effect is fairly homogeneous, so the mean annual lapse rate in the tropics, for example is fairly similar at most altitudes. But the release of latent heat during condensation is not equal at all altitudes and warming at all altitudes would not necessarily reduce the gradient anyway. In fact, one would expect more such warming in the lower troposphere.<br /><br />The effect of reducing the lapse rate is to cool temperatures in the lower 4 or 5Km of the troposphere and raise them in the upper troposphere, so that this all helps to retain radiative balance with the Sun, such as is observed.<br /><br />So where is all the condensation in the uppermost regions of the troposphere and why is there apparently a cooling effect from whatever latent heat is released in the lower altitudes below 4 or 5Km?<br /><br />It’s nonsense what climatologists teach themselves, and the claims made are simply not backed up by physics.<br /><br />Radiation can transfer energy from warmer to cooler molecules within the system being considered, so this transfers energy far faster than the slow process that involves molecular collisions. That is why the gradient is reduced and the reduction also happens on other planets where no water is present. That is why water molecules and suspended droplets in the atmosphere, as well as carbon dioxide and other GHG all lead to cooler surface temperatures.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4142988674703954802.post-88739798287847016042014-02-13T16:46:01.910-08:002014-02-13T16:46:01.910-08:00http://ruby.fgcu.edu/courses/twimberley/EnviroPhil...http://ruby.fgcu.edu/courses/twimberley/EnviroPhilo/FunctionOfMass.pdfMShttps://www.blogger.com/profile/06714540297202434542noreply@blogger.comtag:blogger.com,1999:blog-4142988674703954802.post-26338992420797773492014-02-13T16:34:51.784-08:002014-02-13T16:34:51.784-08:00Alex Hamilton says:

T...Alex Hamilton says:<br />February 13, 2014 at 2:16 pm<br />The assumption relating to climate sensitivity to carbon dioxide is dependent upon an assumption that there would be uniform temperatures in the troposphere in the absence of moisture and so-called greenhouse gases. GH gases are assumed to establish a “lapse rate” by radiative forcing and subsequent upward convection.<br /><br />In physics “convection” can be diffusion at the molecular level or advection or both. It is important to understand that the so-called “lapse rate” (which is a thermal gradient) evolves spontaneously at the molecular level, because the laws of physics tell us such a state is one with maximum entropy and no unbalanced energy potentials. In effect, for individual molecules the mean sum of kinetic energy and gravitational potential energy is constant.<br /><br />So this thermal gradient is in fact a state of thermodynamic equilibrium. If it is already formed in any particular region then indeed extra thermal energy absorbed at the bottom of a column of air will give the impression of warm air rising. But that may not be the case if the thermal gradient is not in thermodynamic equilibrium and is initially not as steep as it normally would be. In such a case thermal energy can actually flow downwards in order to restore thermodynamic equilibrium with the correct thermal gradient.<br /><br />What then is the “correct” thermal gradient? The equation (PE+KE)=constant amounts to MgH+MCpT=constant (where M is the mass, H is the height differential and T the temperature differential and Cp the specific heat.) So the theoretical gradient for a pure non-radiating gas is -g/Cp as is well known to be the so-called dry adiabatic lapse rate. However, thermodynamic equilibrium must also take into account the fact that radiation could be transferring energy between any radiating molecules (such as water vapour or carbon dioxide) and this has a propensity to reduce the net result for the thermal gradient. Hence we get the environmental lapse rate representing the overall state of thermodynamic equilibrium.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4142988674703954802.post-12041370307518482702014-02-13T16:30:11.355-08:002014-02-13T16:30:11.355-08:00Alex Hamilton says:

So the “lapse rate” is already there, and indeed we see it in the atmospheres of other planets as well, even where no significant solar radiation penetrates.<br /><br />In fact, because the “dry” lapse rate is steeper, and that is what would evolve spontaneously in a pure nitrogen and oxygen atmosphere, and because we know that the wet adiabatic lapse rate is less steep than the dry one, it is obvious that the surface temperature is not as high because of these greenhouse gases. Carbon dioxide (being one molecule in about 2,500 other molecules) has very little effect, but whatever effect it does have would thus be very minor cooling.<br /><br />I don’t care what you think you can deduce from whatever apparent correlation you think you can demonstrate from historical data, there is no valid physics which points to carbon dioxide warming.<br /> <br />http://wattsupwiththat.com/2014/02/13/assessment-of-equilibrium-climate-sensitivity-and-catastrophic-global-warming-potential-based-on-the-historical-data-record/#comment-1567041Anonymousnoreply@blogger.com
