The National Climate Assessment (NCA) serves as a status report on climate change science and impacts based on observations made across the country. It incorporates advances in the understanding of climate science into larger social, ecological, and policy systems and serves to integrate scientific information from multiple sources and to highlight key findings and significant knowledge gaps. The First National Assessment report was produced in 2000 and a second, Global Climate Change Impacts in the United States, was produced in 2009. This document, The United States National Climate Assessment–Alaska Technical Regional Report, is one of eight regional reports that will provide input to the 2013 National Climate Assessment. |
