As the sun continues to evolve, grow and get hotter, the climates of earth and Mars will continue to warm. Long before the sun has become a red giant, earth will have lost its oceans due to boiling off. This is not billions of years off. Much sooner, although by then humanity will have evolved into something else or died off altogether anyway. Humanity might have taken its ecosystem into deep space before then or not--looks like not--but that won't stop evolution, and humanity will have become something else by then. Whether it stays and dies with dignity or leaves, the billion hours of a species will end.

Not in Kansas or parts of Pennsylvania.

HAHAHAHA! Now that's funny. Reminds me of the other day when that guy was trying to say he was "evolving", mutating into a creature of the dark because he felt he had better vision in the dark than all other humans.

Read the bible. The end is spelt out much better. No guessing. Man will be around to witness the end of life on this earth.
