1930s photos show Greenland glaciers retreating faster than today

After the expedition returned the photographs were used to make maps and charts of the area, then placed in archives in Denmark where they lay forgotten for decades. Then, in recent years, international researchers trying to find information on the history of the Greenland glaciers stumbled across them.

Taken together the pictures show clearly that glaciers in the region were melting even faster in the 1930s than they are today, according to Professor Jason Box, who works at the Byrd Polar Research Center at Ohio State uni(t).
