11. Actually the Earth will be uninhabitable well before that

And I'm not talking about Anthropogenic Global Warming. As the sun evolves over the next billion years it will grow hotter and hotter. With in one billion years only, though the sun will still be burning hydrogen, it will be so hot as to make the oceans boil. We have time to solve this problem. One of the physicists at the University of Michigan has proposed a "move the Earth a higher orbit" scheme which involves gravitationally assist by passing an asteroid just ahead of our planet every 10,000 years or so to deal with this. But since we can't even form a global concensus to deal with CO2 and Methane which is a much much more pressing and much easier problem it seems unlikely that we will survive the 10's of millions of years into the future when this will begin to actually become a problem.
