In 2003, astronomers at the University of Texas at Arlington performed refined calculations to determine that the habitable zone around 47 Ursae Majoris, where an inner rocky planet (with suitable mass and atmospheric gas composition and density) can have liquid water on its surface, lies between 1.05 and 1.83 AUs of the star.

High density fog, atmospheric anomalies, and severe thunderstorms in an almost liquid atmosphere, will make drone design more challenging and provide unique gameplay.
It's something of an abstract concept, but with real world implications, and the universality of such physical models, based on things like radiative balance, atmospheric composition and density, distance from the local Sun, etc., is a very strong argument in favor of general acceptance of the results of climate models and observations on Earth.
Re 423 Chris G — whether the effect saturates at a given density depends on the way the temperature is distributed; if the temperature from TOA downward is isothermal for a sufficient thickness, than the effect could be saturated at TOA (if starting from a large enough optical thickness per unit atmospheric mass path, a change in the density of the gas / etc that contributes optical thickness would then have little to no effect on the flux at TOA, which is what is meant by saturation.
The only things that can change that resultant point of temperature equilibrium are changes in solar radiance coming in or changes in overall atmospheric density which affect the radiant energy going out.
The only things that can change that resultant point of temperature equilibrium significantly are changes in solar radiance coming in and changes in overall atmospheric density (a function of mass and pressure) which affect the radiant energy going out or a change in the speed of the water cycle which, because of the unique characteristics of the phase changes of water altering the speed of energy flow through the system is capable of exerting a powerful regulatory effect.
For example, let's say that evidence convinced me (in a way that I wasn't convinced previously) that all recent changes in land surface temperatures and sea surface temperatures and atmospheric temperatures and deep sea temperatures and sea ice extent and sea ice volume and sea ice density and moisture content in the air and cloud coverage and rainfall and measures of extreme weather were all directly tied to internal natural variability, and that I can now see that as the result of a statistical modeling of the trends as associated with natural phenomena.
However, I have argued elsewhere, that because of both temperature and density gradients, the escape path to space is favored over the return path to the surface; because of re-absorption in subsequent atmospheric layers.
There were atmospheric CO2 density sets made early in the 1900s, some showing CO2 densities as high or higher than today.
The atmosphere is analogous to a flexible lens that is shaped by the density distribution of the gas molecules, of the atmosphere in the space between the sphere holding them, and space; Incoming heat gets collected in many ways and places,, primarily by intermittent solar radiation gets stored, in vast quantities, and slowly but also a barrage of mass and energy fluxes from all directions; that are slowly transported great distances and to higher altitudes mostly by oceanic and atmospheric mass flows.
For us, one of the most fascinating findings of this analysis is that the atmospheric temperature profiles from the boundary layer to the middle of the stratosphere can be so well described in terms of just two or three distinct regions, each of which has an almost linear relationship between molar density and pressure.
I did not read that «the idea that gravity by itself can create a permanent gradient of temperature in an atmosphere» other then the idea that atmospheric density by itself creates greater heat capacity, thus a longer residence time for energy to saturate while insolation continues unabated.
In fact, atmospheric density is far more important than the proportion of CO2 in dictating the strength of a planet's atmospheric greenhouse effecIn fact, atmospheric density is far more important than the proportion of CO2 in dictating the strength of a planet's atmospheric greenhouse effecin dictating the strength of a planet's atmospheric greenhouse effect.
In atmospheric physics, lidar is used as a remote detection instrument to measure densities of certain constituents of the middle and upper atmosphere, such as potassium, sodium, or molecular nitrogen and oxygen.
As Anthony pointed out some time ago, when looking at the temperature profile of Vensus, where the atmospheric density reaches one bar in the atmospheric column, the temperature is nearly the same as Earth's.
In short, your idea that the temperature of the earth has been remarkably stable over times is correct, and the idea that water seems to dominate also looks correct, but the idea of a stable atmospheric density appears incorrect, and the ancient sun is a complete unknown that needs looking into.
Micro bubbles found in deep polar ice cores of the ancient atmosphere (1 - 200,000 years ago) showed a higher atmospheric density than now, perhaps 2 atmospheres, also higher water vapor and CO2.
It is further argued that the transition of vertical circulation patterns is in response to adjustments to geostrophic imbalance — an adjustment time scale of 6 — 9 h. Although unproven, we suggest that antecedent rainfall over the alkali desert 2 weeks prior to the event was instrumental in lowering the bulk density of sediments and thereby improved the chances for dust ablation by the atmospheric disturbance.
So density weighted temperatures of the entire atmosphere would be a step in the right direction (provided good long - term records for the rest of the atmosphere — which only go back to the 1970s), but strong El Ninos would continue to drive substantial variations in global density weighted atmospheric temperatures.
