It's hard to understand someone that doesn't care about human survival. You lost me. You're so confident in the Earth but you at the least 50% want humanity to go fail.Is that, the Earth this "rock" you call it does not need our intervention. Climate change will occur regardless of our activities. Its the way the Earth cleanses itself. It has its cycles. Everything we produce comes from the Earth and in time will be given back to the Earth. For as long as we are here. However long that may be. And if we somehow disappear, you can be sure that something else will take our place. Until the core goes cold and the planets atmosphere dissipates (see Mars).
Hate to break it to you but humans may just outlive this planet, when it's dead. Cheers.
