Earth Has An Expiration Date
Featured
Description
The sun has been growing hotter ever since its birth. Over time, the sun will also grow larger. This growth will eventually cause a cataclysmic greenhouse event as the Earth moves further out of the sun's habitable zone. Once this happens, oceans that have existed on Earth for billions of years could evaporate in as little as ten thousand. | http://science.discovery.com/tv-shows/how-the-universe-works/
