The remaining remnant glaciers on Punkak Jaya were once part of an icecap that developed approximately 5,000 years ago. At least one previous icecap also existed in the region between 15,000 and 7,000 years ago, when it also apparently melted away and disappeared.

of the New Guinean glaciers indicated that in the two years from 2000 to 2002, the Carstensz Glacier had lost a further 6.8% of its surface area. An expedition to the remaining glaciers on Puncak Jaya in 2010 discovered that the ice on the glaciers there is about thick and thinning at a rate of annually. At that rate, the remaining glaciers in the immediate region near Puncak Jaya were expected to last only to the year 2015. A 2019 study predicted their disappearance within a decade.
The remaining remnant glaciers on Punkak Jaya were once part of an icecap that developed approximately 5,000 years ago. At least one previous icecap also existed in the region between 15,000 and 7,000 years ago, when it also apparently melted away and disappeared.
