What Caused Venus to Become Uninhabitable?

Venus, once a planet with a temperate climate and possibly oceans, underwent a dramatic transformation that rendered it uninhabitable. A runaway greenhouse effect, triggered by volcanic activity and the buildup of carbon dioxide in the atmosphere, led to a rise in global temperatures. This extreme heat caused a catastrophic evaporation of water, resulting in the loss of oceans and the formation of a thick, dense atmosphere composed primarily of carbon dioxide. The extreme heat and pressure on Venus make it one of the most inhospitable planets in our solar system, with a surface temperature hot enough to melt lead and an atmospheric pressure that would crush a human in an instant.
