A kind of unwanted progress…
The Tasman Glacier / Haupapa is the largest glacier in New Zealand and one of several large glaciers which flow south and east towards the Mackenzie Basin from the Southern Alps in New Zealand’s South Island.
The glacier remained at a constant 28 km (17 mi) in length for all of its recorded history in the 20th century before progressing with its current period of rapid melting in the 1990s. Between 2000 and 2008 alone, the glacier receded 3.7 km. Since the 1990s it has retreated, on average, about 180 metres (590 ft) a year.
The glacier is now in a period of faster retreat where the rate of retreat is calculated to be between 477 to 822 metres (1,565 to 2,697 ft) each year. With this rate of progress, it is estimated that the Tasman Glacier will eventually disappear.
