The Actuaries Climate Index® (ACI) is an educational tool designed to help inform actuaries, public policymakers, and the general public about climate trends and some of the potential impacts of a changing climate on the United States and Canada. The index is an objective measure of observed changes in extreme weather and sea levels. It is intended to provide a useful monitoring tool of climate trends and will be updated quarterly as data for each meteorological season becomes available.
