In graduate school and as a mountaineer and nature photographer, I’ve visited many of the world’s great mountain ranges and seen hundreds of glaciers.
In spite of this, I didn’t understand how fast truly enormous quantities of ice could disappear until 2005 when I went to Iceland and shot a story for The New Yorker Magazine. This led to a 2006 National Geographic magazine assignment to document changing glaciers in various parts of the Northern Hemisphere and South America. By the time this cover story was done, the Extreme Ice Survey was born.
