Was Earth a Migratory Planet?
astroengine writes "Why our planet isn't a "snowball Earth" — a dilemma called the 'faint young sun paradox' — has foxed solar and planetary scientists for decades. Since the Earth's formation, a planet covered in ice should have stifled any kind of greenhouse effect, preventing our atmosphere from warming up and maintaining water in a liquid state. Now, David Minton of Purdue University has come up with a novel solution that, by his own admission, straddles science fact and fiction. Perhaps Earth evolved closer to the Sun and through some gravitational effect, it was pushed to a higher orbit as the Sun grew hotter. But watch out, if this is true, planetary chaos awaits."
just so you know, CO2 is a poison.
Also, getting farther away and darkening the atmosphere isn't really a survivable strategy.

Noun:
A substance that, when introduced into or absorbed by a living organism, causes death or injury, esp. one that kills by rapid action.
Counter: It is. Though everything is in large enough quantities. Even water. It is all about the LD50.

In the beginning God created the heavens and the earth. 2 Now the earth was formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters. 3 And God said, “Let there be light,” and there was light. 4 God saw that the light was good, and he separated the light from the darkness. 5 God called the light “day,” and the darkness he called “night.” And there was evening, and there was morning—the first day. Believe it if you want, don't believe it if you don't, but it is enough of an explanation for me. It's something called FAITH. The problem I have with a lot of people is I don't try to shove my belief in god on them, but a lot of them want to shove their non belief on me.
