This time-lapse of Barter Island in Alaska during three summer months in 2014, shows the pack ice melting and the subsequent effects to the beach and permafrost cliffs from storms and summer temperatures. This camera sat on a fallen snow fence to capture storm events. As more storms hit the coast, winter ice no longer sticks around long enough to buffer them, and the waves eat away at the base of...
