How far out of whack can the orbit of a planet like Earth get before we all die?

There is nothing further to see at the above cited, if you are not a subscriber (which I am). But the article can maybe be looked up at your local library.
I'm not up to doing a major review right now, but the essence of the article is that there could be considerable variation in the earths orbit (could be much more eliptical), and earth would still be habitable.
Perhaps that topic would be a better place to pursue that theme?

Added by edit: I just checked the "Discover" link again. There is now quite a bit of content available there, even if you are not a subscriber.
