Alaska Fire Seasons

Here a plot of total acreage burned in Alaska over the past 70 years. Plainly, a few big seasons are sandwiched between summers with much less activity. However, the frequency of "big years" has doubled since the late 1980s. This year is a near certainty to exceed a million acres, which would make this the first time in the period of record with three summers in a row with a million plus acres burned.
