2012 Columbia Glacier, Columbia Bay, Alaska.
Iceberg-choked Prince William Sound reveals that the retreat of the Columbia Glacier is accelerating: It’s lost two more miles of ice in six years. And since 1980 it has diminished vertically an amount equal to the height of New York’s Empire State Building.

2009 Bridge Glacier, British Columbia.
Retreating roughly five feet a day during melt season, the 10.5-mile Bridge Glacier in British Columbia’s Coast Mountains suffers the double whammy of lower snowfall in winter and hotter temperatures in summer. As the glacier shrinks, the lake at its foot keeps growing.
