The National Security, Military, and Intelligence Panel (NSMIP) analyzed the security implications of two warming scenarios: Near Term (1-2oC by mid-century), and Medium-Long Term (2-4oC). The former would pose High to Very High security threats; the latter would pose a Very High to Catastrophic threat to national and global security.  At all levels of warming, climate change will pose significant and evolving threats to global security environments, infrastructure, institutions, and US military missions in all geographic areas.  These threats could come about rapidly.  Mitigating these risks requires reducing and phasing out global greenhouse gas emissions, making infrastructure and institutions “climate-proof”, and integrating these considerations across all security planning.
