This year’s World Economic Forum called for greater urgency in discussing the impacts of climate change on human security and social, political, and economic stability. And a recognition of the destabilizing effects of climate change also has led the UN to emphasize the risks they pose to the most vulnerable populations, including poor, conflict-affected, and displaced persons.

Ever since the CNA’s Military Advisory Board—composed of former U.S. military personnel—named climate change as a “threat multiplier” in a 2007 report, the term has gained widespread currency both in environmental and national security circles. It also has propelled the need to assess and address climate-related security risks higher up overall policy agendas.
