While much of the present concern over climate change has more to do with rises in temperatures and sea levels, could it be that one of the major consequences of a warming planet will end up being a rise in the occurrence of armed conflicts? That’s the scenario proposed in Tropic of Chaos, by the writer Christian Parenti. The recently published book warns convincingly of a “catastrophic convergence” in which long-term political mismanagement and instability collide with deep-seated poverty, along with the added threat of climate shocks in cases where each problem intensifies the magnitude of the next. And what’s more, the convergence is already taking place. If devastating cycles of flooding and drought weren’t reason enough to worry about our climate systems, there’s also the resulting violence that might go with them.
     It’s an interesting thesis from a journalist who has spent more time covering war zones than climate zones. But as Parenti explains, his travels through the parts of the world most rife with conflict led him to observe that a common factor was contributing to the problems in each of them. He noticed that unpredictable changes in weather patterns were putting populations at risk of falling into the trap of poverty and of then fighting over the limited resources that remained. The isolated wars that he thought he was witnessing were but minor skirmishes in a greater war taking shape on a global scale.
