Number: RL32997 Title: Climate Change: Federal Expenditures for Science and Technology Authors: Michael M. Simpson and John R. Justus, Resources, Science, and Industry Division Abstract: For over 25 years there have been federal programs directly or indirectly related to climate change. Direct programs have focused largely on scientific research to improve the capability to understand climate systems and/or predict climatic change and variability. Energy use has been one major focus of efforts related to possible climate change because carbon dioxide, the major "greenhouse gas," is added to the atmosphere when fossil fuels are burned. All those efforts, which sought to reduce oil imports, manage electricity needs, and address environmental concerns including climate change, involve many parts of the government. Climate science efforts in various agencies have sought to expand scientific understanding of the dynamics of climate and its societal consequences as a basis for policy decisions that rely on improved predictions of future climate conditions and climate impact assessments. This report identifies and discusses direct climate-focused scientific and research programs of the federal government, as well as an array of energy programs that relate indirectly to climate change.
