In the early 1900's, Arctic glaciers were nature's most mysterious and undiscovered wonders. Over 100 years of research, exploration, and exploitation later, the glaciers have become a haunting testament to the effects of climate change. Christian Åslund, a Swedish photojournalist who works with Greenpeace, gathered some early photos of glaciers in Svalbard, Norway from the Norwegian Polar Institute, and juxtaposed them next to his own photos of the same locations from 2002. The differences were unbelievable. He's using the photo series to promote #MyClimateAction, a National Geographic campaign encouraging discussion about climate change, and as a protest against Norwegian oil companies drilling in the melting Arctic.
