The Atchuelinguk Fire, an 800-acre tundra blaze near Marshall, Alaska, extinguished naturally. Ipsen said that the fire occurred in an area where blazes are allowed to play out when not threatening known sites of value or people. The cause of the fire has not been determined.

Adding to the concerns are stories of increasingly aggressive foxes in Marshall and other villages. It appears to be a strong year for the fox population, a state biologist said. Marshall is shooting stray dogs to protect village residents.

The loss of frozen ground in Arctic regions is a striking result of climate change. And it is also a cause of more warming to come.
