The arrogance of our species is astounding. Our perceptual timelines are far too short and our reactions are far too erratic. Nature grinds forward - with or without intervention by humans - and with or without the survival of life on this planet. It's not clear to me whether we have the power to remove all life on this planet and make it just another dead, lifeless space rock - I suspect we do not - not as long as the oceans contain micro organisms that can evolve very quickly such that even we can't easily eradicate them. Either way - the universe doesn't give d@mn - and thinking we have the ability to "control" our environment is the height of folly. Our mindset should be to try to survive and live within the current state of the planet - whatever that current state looks like. If the mean temperature of the planet is increasing, fine - then instead of trying to stop the environment's current direction - figure out how to live with the new status quo. Adapt or die - it's as easy as that. Hopefully, the squid will do a better job after we are gone and the squid rise-up to take our niche in the hierarchy.
