The melting and erosion of permafrost is probably the most visible manifestation of climate change in Alaska.

Author and photographer Seth Kantner has a new blog that shares his observations of a changing Arctic in words and images. From trees invading the tundra and freakish weather to the hair-raising loss of the permafrost, it’s a must-read. His phenomenal book Ordinary Wolves (one of my favorites of the last 10 years) takes place in the town of Kotzebue on the northwest coast of Alaska (where he’s from), where the tundra is literally melting away from underfoot and into the sea.
