if you're referring to climate change and i would expect that it would cause the 4th near human extinction event at a minimum; so there's a chance humanity will survive and there will be some sort of a society if it does.

perhaps since we've exhausted most of the easily accessible sources of energy; maybe the next society won't be able to advance past the next stone age on-wards to develop the industrial or technological capabilities that enable such absurd disparities in wealth they can afford to bend the entire world to their will for a genocide; rending 99% of the world helpless as they can do nothing but witness palestinians culled into numbers small enough that isreal no longer considers them a threat.
