The Runaway Greenhouse Effect: When Ocean Planets Boil Away

Quick fact

Venus is the classic example: it likely experienced a runaway greenhouse effect in the past, and its surface temperature now reaches about 460°C, hot enough to melt lead.

Why this is interesting

We know Earth is warming, but did you know that on some planets, warming can become so extreme that entire oceans boil away? Could our planet ever cross that threshold?
