Caption

Near Drew Point, Alaska, along the northern coast. The photo shows how ocean waves have undercut the land nearest the shore. Grassy turf extends out over a wave-cut notch.

Ocean waves slowly eat away coastal cliffs the world over, but in parts of Alaska, these processes have accelerated due to changing climate. There, coastal erosion owes its accelerated pace to two climate-driven phenomena: declining sea ice and thawing permafrost.
