It has been warmer... But we've never been so many people on this planet who really depend so much on a stable climate. We are really pushing this planet to the edge right now even without climate change. If the climate changes, we all have to adapt. Cities with millions near the ocean or in extremely hot areas will have to be relocated. Existing agricultural land will become unusable, and we'll have to come up with new land. We are already using up most the planet's fertile ground on agriculture, so it is not like we can just start using the desert. So you'll have migration and food crisis on your hands... I don't know what your definitions of "wipe out" og "end of the world" are, but it will definitely not be without significant issues.
