The thing is, global warming and overpopulation won't even come close to eradicating humanity. Even if lots and lots of people die (say 3/4 of humanity) that still leaves a population larger than what the human population was for a great portion of history. Famine can't possibly end humanity, as people are smart enough to grow crops in a variety of climates, and near future technology will allow for genetic enhancements of food sources that will make it easy to feed up to 10 billion or so people. Europe and the US essentially grow at a sustenance level. Overpopulation is not an issue here. The US pays farmers not to grow certain crops, because they are too plentiful here. The US could feed twice it's current population in a heartbeat. Eventually India and China will level off their population growth.
As far as environmental issues, some global warming related damage will occur, but the worst of the damage was really done from the beginning of the Industrial Revolution to about 1900. Since 1980 or so, pollution in general is down quite a bit. People will eventually start to take things more seriously, and oil will eventually be scarce enough that a mass switch to renewable energy sources will happen. If China and India can be kept in check, the effects of global warming will be minimized.
I think the biggest threats to people are super-contagious deadly viruses and asteroid hits. Even a devastating virus would not wipe everyone out, considering how spread out across earth people are. Some people would survive and move on.
I also think the age of nuclear threats is basically at an end. Even if terrorists obtain some nukes, 6 billion people is a lot to kill.
