Yeah I was going to see it won't happen in a million. They can estimate the life of the sun and the amount of fuel left relatively accurately since it's right there. It will be at least a billion. As for if the Earth will be uninhabited by then, I estimate we will be so advanced as a species, provided we haven't killed ourselves, that we'll be able to do whatever we want with our Earth long before the warming phase.
