A lot of these causes don't make sense at all. How is overpopulation going to wipe out humans? It's frickin self-correcting. You get too many people they start starving to death and then you have fewer people. It's not like once we hit a global population of 20 billion everyone will suddenly starve to death at the same instant.
Disease is also self-correcting. If a disease is so deadly and infectious that it kills everyone infected then it will burn itself out pretty quickly because all of its vectors are gone. If it isn't %100 lethal than you get some people who are immune that repopulate and the entire population becomes immune to it.
Global warming/climate change? Unless all of our air disappears or the temperature goes up to 60 degrees celsius in a month I don't see how it's going to wipe out every single human. If we assume that climate change is caused by human industry, then if it starts killing people on a massive scale it will also decrease the amount of human industry. This in turn will reduce the climate change. Self correcting again. More likely it will be slow enough process that we can adapt to it as we go.
Racism. Umm you need people alive to have racism. If all the asian people kill all the black people and all the white people, humans still won't be extinct.
War. Same deal. Unless by some chance you have the entire world split into two perfectly matched sides and the last two soldiers left alive in the world shoot eachother at the same time it aint going to make people extinct.
Nuclear war. Nuclear war might involve at most maybe 20 countries or so. That still means that the majority of the earth will still be undestroyed. The remaining countries only have to deal with fall out and nuclear winter. There would be high cancer rates for a few hundred years maybe, but not global extinction. If for some reason Russia and the USA made a deal that they would spread out all their nukes to hit every inhabitable part of the world, yes then it might exterminate all humans.
Animals that go extinct is mostly because the environment changes and they lose their niche. The human niche is so big that if these types of environment changes can't hurt it. We don't rely on any single food source or climate or region to survive.
The only really believable one is meteor strikes which have wiped out most of the life on the earth in the past.
