A mountain in Oceania was stripped of its title as the region's highest peak simply because its neighbour melted slower.

In 1936, the peak of Ngga Pulu in the central highlands of West Papua stood taller than its neighbor, Carstensz Peak, owing entirely to a massive crowning cap of glacial ice.
However, according to records from the World Meteorological Organisation, the glacial system across these peaks has lost more than 99 percent of its coverage since approximately 1850. As the ice sheet retreated, Ngga Pulu physically lost enough elevation to drop below Carstensz, permanently reorganizing the geographical ranking of Oceania's highest summits without any tectonic movement taking place.
The remaining ice around Carstensz Peak has shrunk to approximately 16 hectares. Recent studies conducted on the East Carstensz Glacier by glacial ecologist Marie Sabacka of Charles University and Roberto Ambrosini of the University of Milan revealed that the vanishing ice holds an isolated microscopic ecosystem. Core samples and dark sediment showed lineages of microorganisms and microscopic animals rarely documented on other glaciers, which exist exclusively within this rapidly disappearing tropical ice archive.
