Abstract

Areas with high severity levels are projected to expand into the central and northern parts of the Prairies, north-eastern British Columbia, south-central Yukon, and north-western Ontario. The projections for the forest fire danger levels were based with relation to global warming for the period of 2090 to 2099. The warming impacts may include more frequent and severe fires, shorter growth periods between fires, proportionally younger stands, and a decrease in the carbon storage of northern Canadian forests. The Seasonal Severity Rating, which is a measure of fire danger conditions over a complete fire season, has a relative scale with values above 6 being extreme.
