Smoke plumes from these fires degraded air quality over most of Alaska, inducing the first ever dense smoke advisory for Anchorage, and some of the world’s worst air quality in Anchorage and Fairbanks. Fires are spreading farther north, burning more intensely and starting earlier, in line with what scientists have warned would happen with climate change. Several studies, as well as ongoing satellite monitoring, show that fires are spreading farther north into the Arctic, burning more intensely and starting earlier in the year, in line with what climate models have long suggested would happen as sea ice dwindles and ocean and air temperatures rise.

Extreme wildfires have increased in Alaska, affecting the economy and public health of an entire region. Summer ocean heat waves contribute land heat waves; in the fall, warmer ocean and land temperatures delay the freeze-up of ice near the shore, which leads to even more heat buildup in the ocean, part of the death spiral of the Arctic climate system as we know it, now headed toward an uncertain future, according to scientists.

The normally moist, black organic peat soil and lush forests have been drying, and when they catch fire, they burn relentlessly.
