Honestly, Jared Diamond (the guy who wrote Guns, Germs, and Steel) basically wrote another book called "Collapse" where he looks how several massive powers collapsed, several of them due to climatological chances, causing logistical chaos that made many early empires unable to feed the city-states that ruled their empire.

One exception to this is actually Easter Island because factionalism actually depleted the island's supply of wood, because the large trees were being cut down to support the creation of those giant stone heads and move them into positions in an intra-island culture war. The island was so deforested (and the inhabitants didn't have any forest management), that boats could no longer be built, meaning that the island couldn't engage in trade, and had accidentally isolated itself. This basically caused a massive demographic collapse and turned a late stone-age tribe into an near early stone-age people that wouldn't encounter other humans for hundreds of years until Europeans encountered them.
