Part 3/6:
The transformation of Venus underscores a critical aspect of planetary climate dynamics: if a planet becomes sufficiently hot, gases like CO₂ can escape its atmosphere into space. This loss of gases eventually halts the greenhouse cycle, preventing further warming, but only after a planet has already been rendered nearly uninhabitable. In Venus's case, this cycle resulted in an environment with surface temperatures soaring beyond 800°F (around 427°C). Such extreme heat creates a feedback loop, where increased thermal energy causes more volatile gases to be released or trapped, intensifying the greenhouse effect.
