These Before and After Photos Show How Glaciers in the US Are Melting

Over the past several years, the U.S. Geological Survey has been shooting a "Repeat Photography" project in various locations to show how glacier ice has been retreating over the past century. Using photos from the late 1800s and early 1900s as references, photographers are rephotographing those same scenes to show how things have changed (and are changing).

Photographer Documents a Melting Glacier in Africa with Lines of Fire

For his project "When I Am Laid in Earth," photographer Simon Norfolk traveled to Mount Kenya to photograph the melting away of the Lewis Glacier, the largest glacier on Africa's second tallest mountain. To capture what once was compared to what exists today, Norfolk used gasoline to create lines of fire that mark where the glacier lines once stood.

The photograph above shows where the Lewis Glacier ended in 1934.

Speeding Up Climate Change Through Time-Lapse Photography

The Extreme Ice Survey (EIS) is a multi-year project by National Geographic photographer James Balog that aims to make show climate change in action through time-lapse imagery of glaciers. Balog has 27 Nikon D200 DSLRs pointed at 18 glaciers around the world snapping 8,000 photographs each year while powered by solar panels. His custom-designed rigs -- created through months of trial and error -- also include heavy duty tripods, waterproof cases, and wind-proof anchors. He has also created a documentary film about his project titled Chasing Ice.
