As the planet warms, we can expect an increase in political instability and violence
The US Department of Defence (the Pentagon) states in its 2014 Review:
“Climate change poses a significant challenge for the United States and the world at large. As greenhouse gas emissions increase, sea levels are rising, average global temperatures are increasing, and severe weather patterns are accelerating. These changes will devastate homes, land, and infrastructure. They may worsen water scarcity, lead to sharp increases in food costs and competition for resources. Climate change will increase pressure on economies, societies, and governments around the world, increasing problems like poverty, environmental degradation, political instability, and social tensions which can lead to terrorist activity and other forms of violence.”
