The runaway greenhouse effect on Venus occurred when the planet's surface temperatures rose so high that all its water evaporated, leading to a dramatic increase in atmospheric pressure and greenhouse gas concentrations. This process initiated a feedback loop, where the absence of water led to an inability to regulate temperatures, causing even more heat retention by the thickening carbon dioxide atmosphere. As a result, Venus transformed into an extremely hot environment, with surface temperatures averaging around 462 degrees Celsius (864 degrees Fahrenheit), and a thick atmosphere composed mainly of carbon dioxide, with clouds of sulfuric acid. This phenomenon illustrates how atmospheric conditions can drastically alter a planet's climate and habitability over time.
