Tundra Wildfires in Arctic Alaska Are More Severe Than Any Seen in the Past 3,000 Years
Wildfires in the Arctic tundra of Alaska have reached levels not seen at any point in the last 3,000 years, according to a new scientific study that warns of accelerating climate-driven changes in one of the world’s coldest ecosystems.
The study, conducted by an international team of researchers from Germany, Poland, the United Kingdom, Romania and the University of Alaska Fairbanks, found that tundra fire activity during the past century has surpassed anything recorded since around 1000 B.C. The findings highlight how warming temperatures are reshaping the Arctic landscape in alarming ways.
Researchers used a multidisciplinary approach to reconstruct the region’s fire history by extracting peat soil cores from nine sites north of Alaska’s Brooks Range, along the Dalton Highway betwe...
