This article discusses how, with far-north temperatures rising, Alaska tundra fires proliferate.
In Alaska, where sea ice has shrunk to record lows in places and far-north temperatures have climbed to record highs, dozens of fires are burning the treeless tundra and releasing carbon into the atmosphere.
The latest flurry of Alaska tundra fires has been on the Seward Peninsula, which juts out to the Bering Strait.
