Focus yourself within a 10% area, situated one third up, roughly center:

Indeed Venus is a hot planet, though not as entirely heated from the outside, but instead from the inside out.
Those extremely reflective clouds are not only thick and robust and obviously somewhat acidic, as well as getting cryogenic (worse than icy) cold above 60 km and especially getting extra cryogenic by way of their unavoidable season of nighttime, but they otherwise do tend to insulate whatever geothermal plus the little amount of solar energy that gets through, which is actually quite minimal compared to the all-inclusive 20.5 watts/m2 of global energy escaping, whereas the solar contributed factor of surface heating could be as little as a fourth or roughly an average of 5 watts/m2 because, the daytime surface simply doesn't get all that much illumination (a few percent) of the solar 2650 w/m2 spectrum to work with, and most of that cloud filtered influx isn't IR.
In other words, the vast bulk of solar energy gets reflected, and much of whatever continues inward is getting recycled within the thick layers of those clouds that continually recirculate solar energy in much the same fashion as our oceans recirculate and transport solar energy. Most of the incoming recirculation of IR energy gets moderated or diverted by the S8 layer acting somewhat like a personal protection fire blanket, below which are those mostly CO2 acidic clouds and finally a 5~10 km depth as a layer of mist or fog area of semitransparent atmosphere. Below the acidic fog and mist of micro-droplets that never reach the surface, is where the mostly buoyant and otherwise clear atmosphere as dominated by CO2 is relatively calm and basically inert, though getting hotter as you approach the active surface where that atmosphere is continually replenished and where most of the heat is coming from.
