Will Climate Change Increase Global Conflicts?

According to the IPCC's fifth assessment report, a half-metre sea level rise would displace 72 million people. At six degrees Celsius of warming, warmer areas without air conditioning could become unlivable,. Migration crises, heat stress, sea level rise and broader economic effects on these countries could all contribute to the chances of conflict. Climate change makes it harder to solve coordination problems. For example, it incentivizes dangerous arms races which are even more dangerous when they're between great powers. Because of this, it stands to reason that conflict, especially between powerful nations, increases existential risk.
