As the majority of (tropical) glaciers retreat on a global scale, we analysed area changes of the Puncak Jaya glaciers in South East Asia on West Papua, Indonesia, using high resolution optical satellite imagery, supported by historical glacier accounts. The results show a decrease of total glacier surface area by more than 99 % since 1850 and by ~65 % since the last survey in 2018, with glacier area (in 2024) amounting to 0.165 km² ± 5 %. Puncak Jaya glaciers will likely disappear around 2030.
