When will climate change end the world?

Hi, I’m a young person that’s concerned about my future due to climate change. I’m not scared to die, I’ve come to accept that my life won’t last forever and that we have to embrace death with open arms. I do however, want to live till I’m old. I came here to ask when will climate change wipe out all life on earth? I keep getting 2 answers as to when climate change will end the world, the first is that it will happen in “2050”, the second is that it will happen in “2100”. I’ve also heard that it won’t wipe out all life on earth and that humanity will instead go back to the tribal society days when we had to hunt for our food due to everything getting destroyed and less places being habitable. Which one of these answers is correct? Are none of them correct? Are any of them correct? Which one is it?

Thanks
