プンチャック・ジャヤ
Research presented in 2004 of IKONOS satellite imagery 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.
