I like to look on the bright side, in that climate change will either wipe humans off the map or send us back to the Stone Age so we no longer have any real impact.
Both scenarios will heal the planet, animals will re-populate, and homeostasis will again be restored. Checks and balances. We’ll just be another animal that that got out of control, which nature corrected, like it’s done thousands of times over with every animal that’s ever been out of control.
A healthy world. I like that outcome, with or without us.
