From the Executive Summary: "Current conversations about climate change and its impacts are often rancorous and politically charged. As an organization that is, by law, non-partisan, the Department of Defense (DoD) is precariously unprepared for the national security implications of climate change-induced global security challenges. This study examines the implications of climate change for the United States Army. This includes national security challenges associated with or worsened by climate change, and organizational challenges arising from climate change-related issues in the domestic environment. Given that, the study's starting point is the implications of climate change for the U.S. Army, and the Army is therefore the focus of the analysis and recommendations. That said, much of the analysis involves DoD and other elements of the government, and most of the Army-specific recommendations have parallels that apply to other military services."
