From the Introduction: "This report does not analyze climate change science, the causes of multidecadal climate change, or the experienced or projected effects of climate change. Rather, this report describes activities related to climate change adaptation within the Department of the Interior (DOI). The information in this report reflects the state of climate change adaptation activities within DOI and its agencies as of the end of 2020 and does not address activities undertaken under the Biden Administration. Climate change adaptation activities described herein have been implemented both through administrative actions (e.g., executive and secretarial orders and actions taken within agencies' discretion under existing statutory authorities) and pursuant to statutory requirements. This report provides an overview of selected DOI departmental and agency policies, programs, and actions (herein collectively referred to as 'activities') aimed at adapting to experienced and projected effects of climate change. This report focuses on activities related to 'adaptation' to climate change rather than activities related to the 'mitigation' of climate change. For the purposes of this report, 'adaptation' includes activities undertaken to adjust to and prepare for, including through research, the experienced or projected effects of climate change; 'mitigation' includes activities directed at reducing the magnitude of climate change."
