Integrated Assessment of Global Climate Change

The goal of the program is to reveal key insights into the long-term, complex interactions of human and natural systems and their implications in a changing climate and changing world, delivering science-based models and tools that inform national and regional decision-making, and integrated perspectives, on mitigation, adaptation, and long-term energy sustainability and vulnerability.

Program Description

The Integrated Assessment Research Program (IARP) supports research on models and tools for integrated analysis of both the drivers and consequences of climate change. Past work has focused on drivers, specifically sources of greenhouse gas emissions within a common, most often economic and risk-based, modeling framework. Until recently, only modest attention and resources were devoted to modeling the interactive effects of consequences, that is, impacts and adaptation, but this is now a major focus for the program. Additionally, future Integrated Assessment Models (IAM) will need to go beyond a national focus to better provide regional insights and perspectives. While IAMs have already proven their worth as critical decision tools, next generation models will be developed to provide broad-based vulnerability analyses spanning multiple, interactive stressors; analysis of the role of science and technology in both mitigation and adaptation; assessment of the combined economic effects of different response strategies and policies; and improved interoperability across various spatial and temporal scales and levels of modeling detail and complexity. These models will also be challenged more extensively to explore key intersecting systems and their interdependencies, such as found at the energy, water, and land nexus and in connected infrastructure dynamics .

Program Funding Opportunity Announcements

Announcements are posted on the DOE Office of Science Grants and Contracts Web Site and at grants.govExternal link Information about preparing and submitting applications, as well as the DOE Office of Science merit review process, is available at theDOE Office of Science Grants and Contracts Web Site. For current announcements visit BER Funding Opportunities.

The most recently closed Announcement (DE-FOA-0000219) requested applications for a single, coordinated research effort that would: 1) advance progress on a select set of major scientific challenges in the field of Integrated Assessment that are widely recognized and confronting the major Integrated Assessment modeling teams, 2) advance methods and capabilities for inter-model testing and diagnostics, and 3) enhance capabilities for multi-model, "ensemble-like" analyses for improved insights in science studies and science-based analyses.

Why the Program's Research is Important

Climate change is real, its effects are more immediate and profound than previously anticipated, and old questions (are humans the cause?) are yielding to new: What are the impacts? Who and what will be most vulnerable? What can we do about it, and how can we prepare? Against this backdrop, and with an eye toward:

  • regional and local scale insights
  • quantitative predictions at the decadal, annual and even shorter time scales
  • policy-making, planning and decision support tools
  • impacts, adaptation, and vulnerability studies, and
  • highly integrated analyses spanning energy, environment, and economic security,

New or vastly improved Integrated Assessment Models will inform some of the most significant U.S. energy and other infrastructure decisions and investments of this century. In short, these models shape our fundamental understanding of climate change: the drivers, its pace, its consequences, the implications and role for energy systems of the future, changes in availability of natural resources, food, and water, and shifts in global economies, vulnerabilities and overall national security.
