Fire seasons are changing, and Alaska Climate Adaptation Science Center science is trying to help fire managers prepare.

Jeremy Littell, an AK CASC research ecologist, is presenting on what those changes might look like in a webinar for the Alaska Fire Science Consortium Tuesday, April 21.

Littell will explain how future projections from ALFRESCO fire modeling and the Canadian Forest Fire Danger Rating System (CFFDRS) may be used to plan for future changes in fire regimes and weather.
