The National Climate Assessment (NCA) is a United States government interagency ongoing effort on climate change science conducted under the auspices of the Global Change Research Act of 1990. The NCA is a major product of the U.S. Global Change Research Program (USGCRP) which coordinates a team of experts and receives input from a Federal Advisory Committee. For the Third National Climate Assessment, released in 2014, USGCRP coordinated hundreds of experts and received advice from a sixty-member Federal Advisory Committee. NCA research is integrated and summarized in the mandatory ongoing National Climate Assessment Reports. The reports are "extensively reviewed by the public and experts, including federal agencies and a panel of the National Academy of Sciences. The First National Climate Assessment was published in 2000.〔The First National Climate Assessment Report was "prepared by the National Assessment Synthesis Team (NAST), an advisory committee chartered under the Federal Advisory Committee Act to help the US Global Change Research Program fulfill its mandate under the Global Change Research Act of 1990. The National Science and Technology Council forwarded the report to the President and Congress for their consideration as required by the Global Change Research Act. Administrative support for the US Global Change Research Program is provided by the University Corporation for Atmospheric Research, which is sponsored by the National Science Foundation (NCA 2000)."〕 Between 2002 and 2009, USGCRP previously known as the U.S. Climate Change Science Program (CCSP), produced twenty-one Synthesis and Assessment Products (SAPs).〔 The second NCA was published in 2009 and the third was released in 2014. NCA's overarching goal according to their May 20, 2011 engagement strategy summary, "is to enhance the ability of the U.S. to anticipate, mitigate, and adapt to changes in the global environment (NCA 2011:2)." According to the USGCRP official website the NCA, In 2013, the President's Climate Action Plan〔Barack Obama’s 2013 climate action plan〕 released by the Executive Office of the President specifically noted the importance of the National Climate Assessments in achieving the goal of "Using Sound Science to Manage Climate Impacts". ==Global Change Research Act== The National Climate Assessment (NCA) is conducted under the auspices of the Global Change Research Act of 1990. The GCRA requires a report to the President and the Congress every four years that integrates, evaluates, and interprets the findings of the U.S. Global Change Research Program (USGCRP); analyzes the effects of global change on the natural environment, agriculture, energy production and use, land and water resources, transportation, human health and welfare, human social systems, and biological diversity; and analyzes current trends in global change, both human-induced and natural, and projects major trends for the subsequent 25 to 100 years. The Federal government is responsible for producing these reports through the U.S. Global Change Research Program (USGCRP), a collaboration of 13 Federal agencies and departments. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「National Climate Assessment」の詳細全文を読む スポンサード リンク
