Impacts of Climate Change on Biodiversity, Ecosystems, and Ecosystem Services: Technical Input to the 2013 National Climate Assessment.
Scientific assessments are essential tools for linking science and decision making. They survey and synthesize science, within and between disciplines and across sectors and regions. They highlight key knowledge that can improve policy choices and identify significant gaps that can limit effective decision making. Assessments also track progress by identifying changes in the condition of the Earth, changes in human response, and advances in science over time. Assessments have been integral components of USGCRP since our inception. We have a legal mandate to conduct a National Climate Assessment (NCA) every four years, the third and most recent of which was released in May 2014.
