Actuaries Climate IndexTM Updates for Fall 2016

On June 28 2017, organizations representing the actuarial profession in Canada and the United States updated the Actuaries Climate IndexTM, an objective, quarterly measure of changes in extreme weather frequency and sea level, available online at For the United States and Canada combined, the Actuaries Climate Index value for fall 2016 was 2.07, the highest seasonal level recorded.

Updates for values will be posted quarterly on the ACI website as data for each meteorological season becomes available. The organizations are also developing a second index, the Actuaries Climate Risk Index, to measure correlations between changes in the frequency of extreme events as measured by the index and economic losses, mortality, and injuries.

The ACI partnership includes the American Academy of Actuaries, the Canadian Institute of Actuaries, the Casualty Actuarial Society, and the Society of Actuaries. The Climate Change Committee appointed by these organizations established a Climate Index Working Group which worked with climate scientists from Solterra Solutions to develop the index.
