I'm going to assume this is a serious comment and that you are attributing global warming as the cause of the feared extinction. In that case I think you should dial it back a bit. Humans are pretty adaptable. Even assuming the changes in temperature and sea-level are on the high end of predictions, we will adapt. People will move, infrastructure will be built, and so on. Mass extinction certainly isn't going to happen from global warming as we understand it today. You might argue there there will be mass casualties, but that is also uncertain, difficult to quantify, and is quite a different thing than 'mass extinctions'. Of course, mass casualties due to weather has and is already a problem -- it isn't something that is uniquely associated with global warming.
