Most likely climate change will make humans extinct but I wonder if all humans - poof!- disappeared in a sci-fi fashion, would that fix the Earth? In 70,000 B.C., a mega-colossal volcano called Toba blew up and humans almost went extinct. Some say almost down to 40 breeding pairs. 12,000 years ago megafauna went extinct due to humanoids and global warming. So is this a repeat of history or the end of human history? I'm pretty sure the Earth will carry on no matter what unless everybody nukes out simultaneously & cracks the world into pieces.

Yes, the Milankovitch cycle, where we are supposed to be going into another mini ice age about now. Last one was the Medieval/Dark Ages.
