The Climate Change Impacts and Risk Analysis (CIRA) project quantifies the physical effects and economic damages of climate change in the United States (U.S.). Using detailed models of sectoral impacts (e.g., human health, infrastructure, and water resources), the project seeks to quantify and monetize how risks, impacts, and damages may change in response to greenhouse gas mitigation and adaptation actions. This web area provides access to peer-reviewed journal articles, technical documentation, and reports from the project.
