Climate Impacts and Risk Assessment (CIRA) Modeling


  • To effectively combat climate change, we must quantify impacts across multiple domestic sectors.
  • Abt’s multi-disciplinary teams develop rigorous analytical methods to measure those impacts.
  • Our findings provide context for decision-makers, and are featured in numerous peer reviewed publications.
The Challenge

Abt Global’s staff has developed and implemented spatially specific modeling approaches for the U.S. Environmental Protection Agency (EPA) to quantify, and often estimate the cost of, the impacts of climate change on a number of sectors and dynamics in the United States.

These include:

  • Coral reef cover and visitation;
  • Terrestrial ecosystem carbon storage;
  • Wildfire frequency and severity;
  • Fishing and winter recreation;
  • Coastal and inland flooding damage;
  • Bridge degradation and replacement;
  • Water supply and demand;
  • Vector-borne disease;
  • Labor supply; and
  • Human mortality associated with extreme temperatures (heat and cold).
The Approach

Our ongoing research includes efforts on inland flooding and tick-borne disease. Our work coordinates efforts across in-house interdisciplinary teams of experts as well as external consultants.
