The consequences of climate change will be multifaceted. Each region of the world will face unique threats that range from extreme weather to rising sea levels to increased drought. These threats will interact with other vulnerabilities to exacerbate existing tensions. Southeast Asia is uniquely vulnerable to the growing threats of climate change. Highly reliant on fishing and often living on the ocean’s edge, Southeast Asian coastal communities there will face some of the worst impacts. Their high dependence on the ocean and fisheries, both of which will be seriously affected by climate change, will drive the overall security and stability of the region.
