Franz Josef Glacier
Where on Earth is Franz Josef Glacier?
Franz Josef Glacier is approximately 6.8 miles (11 kilometers) long and is located in the Southern Alps on the south island of New Zealand at a latitude of 43.47° South and a longitude of 170.19° East. It begins as an alpine glacier at an elevation of about 11,500 feet (3500 meters) and ends at the bottom of a valley at about 790 feet (240 meters) in a temperate rainforest. Franz Josef is the alpine glacier with the lowest elevation terminus of any alpine glacier in the world.

Until recently, Franz Josef Glacier was spared the fate of retreat that most of its neighboring glaciers in the Southern Alps are experiencing. However, from 1999 to 2005, it began losing mass, but then made a slight comeback from 2005 to 2008. It has since started retreating again; and according to a study done by Anderson (2008), it will continue to decline into the 22nd century.
Franz Josef has not seen as much retreat as other glaciers in the Southern Alps region because it lies on the western side of the divide where it gets greater snow fall and is protected from wind and sun, whereas its neighbors to the east are not as lucky. Because of this, Franz Josef is more slowly affected by a warming climate; hopefully, we still have time to save this glacier.

"The results indicate that [...] the glacier will retreat 5 km and lose 38% of its mass by 2100" —Anderson et al. (2008)
Because of the revenue generated by tourism around Franz Josef Glacier, it is highly monitored. A study done in 2008 by Anderson et al concluded that Franz Josef would lose approximately 38% of its mass by 2100.

In the geography department at the University of Canterbury in Christchurch, New Zealand, researchers are studying Franz Josef to determine the connection between climate change and glaciers.
