Indonesia Reaches New Level of Climate Change, BRIN Study Reveals

TEMPO.CO, Jakarta - Researchers from the National Research and Innovation Agency (BRIN) disclosed that Indonesia has reached a new level of climate change. This finding is based on an analysis of several key indicators in a long-term climate study from 1990 to a 2050 projection.

Erma Yulihastin, a researcher from BRIN's Climate and Atmosphere Research Center, stated that this new phase reflects Indonesia's regional response to atmospheric temperature fluctuations, which are increasing by around 1.5 degrees Celsius.

"As Indonesia is dominated by the ocean, the responses of each region to climate change are not uniform," Erma said in a written statement on Monday, June 30, 2025.

One of the main impacts identified is the alteration of seasonal patterns. The rainy season now tends to last longer, yet dry days without rain are becoming more frequent. Conversely, the intensity of heavy and extreme rains has increased in several regions, including the southern part of Sumatra, the western part of Java, the southern part of Kalimantan, and the southern part of Sulawesi.

The dry season has also experienced changes, becoming wetter, especially in Indonesia's southern regions. The central and eastern parts of Java, Bali, Lombok, and Nusa Tenggara have recorded an increase in the frequency of extreme rains.

In the western part of Sumatra, Jambi, Pekanbaru, and most central areas of the island, extreme rain is predicted to occur more frequently.

Java has undergone significant changes in maximum and minimum temperature variations. "In this case, northern regions of East Java, including Surabaya, will be more frequently exposed to extreme maximum temperatures," Erma said. Meanwhile, the western part of Java will experience lower minimum temperatures more frequently.

According to Erma, this changing temperature variation in Java has the potential to strengthen the intensity of land-sea winds and increase wind instability over land. This could lead to more intense storms and more frequent extreme weather across Java.

For Kalimantan, there are distinct differences between East and West Kalimantan in their response to climate change. "West Kalimantan tends to face more threats of extreme rain, while East Kalimantan and South Kalimantan are facing future drought threats," she stated. Higher air temperatures are expected in the eastern, central, and southern regions of Kalimantan.

The results of this study have been published in various international scientific journals and serve as an important reference for understanding and mitigating the future impacts of climate change in Indonesia.
