Drought, crop failure, submerged coastal cities, mass migration, armed conflict - those are the kind of horrors we can look forward to if the world fails to get its collective act together on climate change, and temperatures and sea levels continue to rise.
Climate security enthusiasts agree that global warming is, well, a global issue. It cuts across national boundaries, and while most people on the planet will be affected by climate change in some way, it's likely to be the poorest who suffer the worst.
A group of disasters experts argue in their report "Climate Change and Human Security" that climate change will affect both "inter-state relations and international and national security in a narrow, geo-strategic sense" and "the well-being and survival of human beings and humankind and thus human, water, health and livelihood security".
