Climate change made Indonesian fires more severe, say scientists
A University of Melbourne wildfire researcher said September 2026 was Indonesia’s fifth-driest September since 1991, with below-normal rainfall across 84% of the country.
Indonesian wildfires from August to October intensified due to record-breaking heat driven by human-induced climate change, according to scientists. A report by World Weather Attribution found that additional heat contributed around 1.6 degrees Celsius during the fire season, exacerbating a very strong El Niño that caused extreme rainfall shortages in Indonesia.
Researchers noted that the extreme weather conditions for these fires would not have occurred without human-induced climate change. Additionally, decades of deforestation and peatland drainage for industry and agriculture have made Indonesia's landscapes more vulnerable to ignition, with September 2026 being the fifth-driest since 1991.
The independent geo-monitoring platform Nusantara Atlas reported that almost 2.88 million hectares of Indonesian territory were affected by fire from January to October 2026, a 35% increase compared to the same period in 2019.
