During the climate conference COP21 in Paris, the US White House plans to post photos on its website illustrating the effects of climate change. The first such photo is of Sólheimajökull glacier, South Iceland.
This is what the glacier looked like eight years ago. The photo was taken by James Balog.
Time-lapse images show how the glacier has receded in the past eight years.
