Our sun is approximately half way through it 10 billion year lifespan. In another 5 billion years the sun will swell to become a giant and engulf the Earth thereby ending all human life with it's demise. But even before that time- in approx 1 billion years time the sun will be about 10-15% hotter than it is at present time which means the oceans will boil away and humans will die out soon after that. My question is do you think the human race will last another 1 billion years to see take place or will we become extinct due to some other reason e.g nuclear war, asteroid/comet, pollution, global warming etc etc. Even if we don't blow ourselves up with a nuclear war the odds are stacked against us as far as nature goes- but will our demise be man made or will it be natural?

With regards to the the sun burning up, 1 billion years is a loooong time away. I think we will be technologically advanced enough to do something about it (i.e. move to another planet or solar system).
