A multi-decadal analysis of fire in Alaskan tundra ecotones was completed using records from the Alaska Large Fire Database and an analysis of future fire potential was performed based on future climate scenarios and the Canadian Fire Weather Indices (FWI).  The authors analyze tundra fire potential in different tundra areas and conclude that most areas will see substantial increase in the number of high-fire-potential days in the next few decades.  This figure shows, for example, the Seward Peninsula and Southwest areas with historical (1951-2005) fire weather indices and modeled with 3 different climate projections to 2095.  Although the Seward Peninsula FWI only exceeded 20 twice in the historical record (1977 & 2005), it is projected to exceed 20 much more frequently in the  next decades.  Read the full article:  French, N.
