Uhm... what? Climate change won't wipe out humanity, no matter how bad it gets, but hundreds of millions of people are at risk of suffering a lot from it, particularly in impoverished nations due to drought causing deadly heat waves, food, and water shortages etc. but according to you that is good because then we have reduced the population?

Overconsumption is the problem, not overpopulation. As long as unrestricted capitalism reigns supreme this won't end.
