The glacier on Puncak Jaya in Papua, Indonesia, the Earth's highest island, is quickly melting away, giving geologists little time to extract ice core samples.
A team of scientists is climbing Indonesia's tropical glacier, Puncak Jaya, to dig out ice cores and study them for past patterns of climate change. They will also study samples from China, Peru, and Kenya.
Melting ice on Mt. Kilimanjaro is mirrored on other tropical summits around the world affected by global warming.
