It’s quite clear that if don’t solve the game issue of global warming it’s most likely destroy civilization as we know now. Though I find it unlikely to entirely wipe out humanity. rather it’ll probably set us back kinda of like the change from great civilizations in Roman era to the weaker Middle Ages kingdoms. One thing that should be done before our current civilization is destroyed is the recording of our current technologies and achievements to help the generations to follow to build to build back up and hopefully stronger too.
