This document discusses the relationship between climate change and international security. It examines four aspects of security that may be impacted by climate change: human security, national security, international security, and ecological security. It explores predictions about impacts of climate change like rising sea levels and temperatures. It also analyzes how climate change may fuel conflicts over issues like water and displace large numbers of climate refugees. However, the document concludes that assumptions about "climate wars" are overstated and not supported by reality. International cooperation and complementary legal protections can help manage issues like water disputes and displacement of climate refugees.
