LOL Thing is stuff like this is going on all the time. Our bodies are tough enough to withstand most of it. Even the pole flips won't do any long-term damage, except to the GPS system, but even that can be compentsated for.
The next Ice-Age is being over-doomed, we still have a good 10-15000 years, which is a long long time from a human standpoint.
Cometary collision... well, I believe I mentioned a 3D no friction snooker table 200km long in HLP
Things aren't bad, but we would be fools to consider things stable.
Edit : Oh, and if this thread gets too intense, feel free to close it, the original purpose was to point out that we are a special kind of creature that has earned it's place on Earth, and to say the those who believe in Evolution can be just as proud as any Creationist for their origins, not to start a Evolution/Creation argument
That is the point of the whole thread I suppose,
despite the fact that the Earth has bounced from one 'Environmental disaster' from our point of view, to the next. Despite that, here we are, the outcome of those which survived all of it, humans, cockroaches and all
