“ A study by U.S. Geological Survey scientists published in February found that erosion along a stretch of Alaska coastline during 2002 to 2007 was twice as fast as in the period from 1955 to 1979. That USGS study also found erosion occurring at a rate of 13.6 meters (44.6 feet) annually from 2002 to 2007.
The three-year study from the University of Colorado used time-lapse photography, global positioning systems, meteorological monitoring, and analysis of sediment and sea-ice distribution with photographic images snapped every six hours during the around-the-clock sunlight of summer showed the rapid rate of decline were alarming. They showed the cliffs being gouged out one large piece at a time. It looks as if a giant continues to rip out large chunks of the cliffs. The cliffs are more than half ice so warm water, stronger waves and higher wave action quickly carves these cliffs
