Head of the Meteorology, Climatology and Geophysics Agency (BMKG) Dwikorita Karnawati said the impact of global warming is increasingly real in Indonesia and the BMKG predicts that the ice cover in Puncak Jaya, Papua, will completely disappear by 2025.

“It will be gone, so of course if Puncak Jaya Wijaya has no ice, it means that global warming has really taken place, and getting ready for extreme weather will become normal,” said Dwikorita in his keynote address for the launch of a Sustainable Development Policy Document.

Based on research conducted by the BMKG team in Puncak Jaya, in June 2010 the thickness of the ice there reached 31.49 meters. The ice thickness decreased by ~ 526 meters from 2010 to 2015, averaging ~ 1.05 meters per year.
However, it is known from subsequent studies that the ice thickness has decreased by ~ 5.7 meters from November 2015 to November 2016. It was a year with strong El Nino.
In February 2021, the ice loss in Puncak Jaya has reached 23.46 meters. So the BMKG predicts the ice cover there will disappear by 2025, according to Dwikorita.
Previously, he explained that the trend of greenhouse gas (GHG) emissions in Indonesia, based on data from 1981 to 2020, seems to be fluctuating. Carbon dioxide (CO2) concentrations are still below global averages, but some graphs that are higher than the global average are strongly associated with the incidence of forest and land fires triggered by climate extremes.
