1930s photos show Greenland glaciers retreating faster than today • The Register
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.
...It now appears that the glaciers were retreating even faster eighty years ago: but nobody worried about it, and the ice subsequently came back again. Box theorises that this is likely to be because of sulphur pollution released into the atmosphere by humans, especially by burning coal and fuel oils. This is known to have a cooling effect.

Box would be wrong. According to ice cores, aerosols were greater pre-1940, than post 1940.
