That is wrong, wogoga.The discussion of 2010 has shown that the extremely high temperature on Venus' surface is at most marginally influenced by a greenhouse effect.
This discussion from 2010 showed that you did not understand the physics behind the extremely high temperature on Venus' surface.
This post shows that in the lest 6 years you have still not learned about the physics involved.
Atmosphere of Venus
An atmosphere that is 96.5% carbon dioxide supports an extreme greenhouse effect. This is physics, not a "result of ideology".The atmosphere of Venus is the layer of gases surrounding Venus. It is composed primarily of carbon dioxide and is much denser and hotter than that of Earth. The temperature at the surface is 740 K (467 °C, 872 °F), and the pressure is 93 bar (9.3 MPa).[1] The Venusian atmosphere supports opaque clouds made of sulfuric acid, making optical Earth-based and orbital observation of the surface impossible. Information about the topography has been obtained exclusively by radar imaging.[1] Aside from carbon dioxide, the other main component is nitrogen. Other chemical compounds are present only in trace amounts.[1]
NASA climate modeling suggests Venus may have been habitable is simply that physics that works for Earth will work for other planets! The climate models that have been shown to work for our climate will also work for the climates of other planets such as Venus.
If a planet has "always been radiating away more energy than receiving from the Sun" then it cools down, not heats up!

''The original greenhouse effect:
The sun heats the ground of a greenhouse, the ground heats the air, and the glasses prevent the hot air from flowing outside the greenhouse''
no the basic statement is wrong
sun light heats the air
windoz trap the heat retaining it in the air
some heat is lost to the ground
but later returned by the ground to the air at night
also trapped by the windoz
he is claiming the air is only heated by the ground
not by the lights passage thru the air
starting with bad data seldom get a good result

so how did it retain so much dense atmosphere
It didn't.
It generated all the CO2 by dissolving the carbonate rocks and releasing the CO2 to the atmosphere.
The deuterium is the big clue.
