If 90% of the human population on earth would just disappear tomorrow morning, would climate change just stop and become a non-issue? Or would it just be pushed back for a little while?

Please re-read my original comment.

I'm saying that there's disagreement about the degree to which humans are contributing to global warming, and can influence climate change, one way or another, in any meaningful way.
