we know that fraudcurrents is a thoughtless troll who will not consider contray science or logic on this subject... but you need to be more scientific... nitro...
there are plenty of variables besides co2 to be considered -
the density of the gases and convection
proximity to sun
other greenhouse gases like water vapor
come on man... be scientific and use the properly level of equivocation...
science does not know that co2 is responsible for the greenhouse effect on venus... its just speculation... for instance wikipedia has this... notice the due equivocation in the first sentence.... "may"...

A runaway greenhouse effect involving carbon dioxide and water vapor may have occurred on
Venus.
[9] In this scenario, early Venus may have had a global ocean. As the brightness of the early Sun increased, the amount of water vapor in the atmosphere increased, increasing the temperature and consequently increasing the evaporation of the ocean, leading eventually to the situation in which the oceans boiled, and all of the water vapor entered the atmosphere. On Venus today there is little water vapor in the atmosphere. If water vapor did contribute to the warmth of Venus at one time, this water is thought to have escaped to space. Some evidence for this scenario comes from the extremely high Deuterium to Hydrogen ratio in Venus' atmosphere, roughly ~150x that of Earth, since light hydrogen would escape from the atmosphere more readily than its heavier
isotope,
Deuterium.
[10][11]Venus is sufficiently strongly heated by the Sun that water vapor can rise much higher in the atmosphere and be split into
hydrogen and
oxygen by ultraviolet light. The hydrogen can then escape from the atmosphere and the oxygen recombines. Carbon dioxide, the dominant greenhouse gas in the current Venusian atmosphere, owes its larger concentration to the weakness of carbon recycling as compared to
Earth, where the carbon dioxide emitted from volcanoes is efficiently
subducted into the Earth by plate tectonics on geologic time scales.

No man did not create runaway climate change on Venus. My point is that it can happen, with or without mans' help. My further point is that greenhouses gases are clearly the smoking gun, regardless of initial conditions, and if humans as a side effect of their everyday living burn carbon fuels, we will contribute to whatever catastrophe Venus endured naturally.
Global Warming is the limit point of too much greenhouses gases in your atmosphere. The rest is details.
