Will Earth's Ocean Boil Away?
Description: Venus has a thick atmosphere that is 96.5 percent carbon dioxide. The planet's water boiled off to space long ago. Could that really happen on Earth?

As carbon dioxide warms the planet through the greenhouse effect, more water evaporates from the ocean-which amplifies the warming, because water vapor is a greenhouse gas too. That positive feedback is happening now. Some scientist argue fossil-fuel burning could cause the process to run out of control, vaporizing the entire ocean and sterilizing the planet.
