Atmospheric Pressure vs Surface Temsp{See Ned Nikolov} "Ever wondered, what the Earth's surface temperatures would be under different atmospheric pressures?"

"This graph shows results from the latest extended NZ planetary temperature model based on the best available NASA data for Venus, the Moon, Earth, Mars, Titan and Triton. These planetary bodies were used to derive universal thermodynamic relationships (valid over a huge range of physical environments) between surface temperatures one hand and pressure, atmospheric density & incoming solar radiation on the other."

"The predictions for Earth depicted here are so accurate that you can take them to bank, as the saying goes."
The green curve shows average latitudinal temperatures under the current pressure (0.9855 bar).

"The overall pattern is that an increasing atmospheric pressure raises the mean global temperature while reducing the latitudinal temperature gradients at the same time. Thus, the higher the total pressure, the more isothermal the planet becomes! That's because molar air density increases with pressure, and a higher density makes the meridional heat transport more efficient due to the presence of large number of molecules per cubic meter carrying heat. Venus with its 93 bar of surface pressure is an example of an isothermal planet surface caused by a very high atmospheric molar density... The relationships are strongly non-linear, however."

Abstract

Past studies have reported a decreasing planetary albedo and an increasing absorption of solar radiation by Earth since the early 1980s, and especially since 2000. This should have contributed to the observed surface warming. However, the magnitude of such solar contribution is presently unknown, and the question of whether or not an enhanced uptake of shortwave energy by the planet represents positive feedback to an initial warming induced by rising greenhouse-gas concentrations has not conclusively been answered. The IPCC 6th Assessment Report also did not properly assess this issue. Here, we quantify the effect of the observed albedo decrease on Earth’s Global Surface Air Temperature (GSAT) since 2000 using measurements by the Clouds and the Earth’s Radiant Energy System (CERES) project and a novel climate-sensitivity model derived from independent NASA planetary data by employing objective rules of calculus. Our analysis revealed that the observed decrease of planetary albedo along with reported variations of the Total Solar Irradiance (TSI) explain 100% of the global warming trend and 83% of the GSAT interannual variability as documented by six satellite- and ground-based monitoring systems over the past 24 years. Changes in Earth’s cloud albedo emerged as the dominant driver of GSAT, while TSI only played a marginal role. The new climate sensitivity model also helped us analyze the physical nature of the Earth’s Energy Imbalance (EEI) calculated as a difference between absorbed shortwave and outgoing longwave radiation at the top of the atmosphere. Observations and model calculations revealed that EEI results from a quasi-adiabatic attenuation of surface energy fluxes traveling through a field of decreasing air pressure with altitude. In other words, the adiabatic dissipation of thermal kinetic energy in ascending air parcels gives rise to an apparent EEI, which does not represent “heat trapping” by increasing atmospheric greenhouse gases as currently assumed. We provide numerical evidence that the observed EEI has been misinterpreted as a source of energy gain by the Earth system on multidecadal time scales.
