With an elevation of over 4600 metres, Carstensz Glacier is one of the last few glaciers found in the tropics, but due to global warming, the glacier is not expected to exist at all by 2030.
The Carstensz Glacier is found near the a sub-peak of Puncak Jaya, Carstensz East. Puncak Jaya is a mountain in the Sudirman Range of the island of New Guinea, territorially the eastern highlands of Central Papua, Indonesia. The glacier is situated at an elevation of approximately 4,660 metres (15,290 ft) and is 1.5 kilometres (0.93 mi) east of the summit tower of Puncak Jaya. In 2002 the Carstensz Glacier was 1.4 kilometres (0.87 mi) in length and .60 kilometres (0.37 mi) wide. In November 2025 it was only 440 metres (1,440 ft) length and 100 metres (330 ft) wide.
