Climate activists gathered Sunday in the Swiss Alps to protest and mourn receding glaciers.
A black and white photograph shot in 1891 dramatically illustrates the shrinking of Switzerland's Trient glacier.
More than 200 activists walked to the foot of the glacier on one of western Europe's tallest mountain ranges.
They rallied to draw attention to the impact of climate change on Switzerland's natural landscape.
Their protest came one day before the Swiss parliament begins debating new legislation on reducing CO2 emissions.
The government says 90% of the remaining 15-hundred Swiss glaciers will vanish by the end of the century if nothing is done to cut emissions.
The Trient glacier has already receded by more than six-tenths of a mile over the last 30 years.
