Fires Char New Guinea

Emissions on both sides of the island are unusually high as human-set fires spread in a landscape parched by drought. NASA Earth Observatory Oct 22, 2026 Article View more Images of the Day: Oct 21, 2026 Instruments: NOAA-20 — VIIRS Topics: El Nino Southern Oscillation Wildfires New Guinea, the world’s second-largest island, harbors an extraordinary variety of plant life across more than a dozen distinct ecoregions, including seasonally dry savannas, tropical rainforests, and lowland swamp forests. But in September and October 2026, as drought gripped New Guinea (sometimes called Papua) amid a strong El Niño, fires scorched the island and smoke shrouded large swaths of it for weeks.

The VIIRS (Visible Infrared Imaging Radiometer Suite) on the NOAA-20 satellite captured this image of thick smoke streaming from the southern part of the island on October 11, 2026. In recent weeks, soaring levels of air pollution delayed and canceled flights, closed schools, and prompted officials in some areas to urge children and older people to wear masks. "Sometimes smoke that has drifted into the convection of nearby thunderstorms will get washed out or lofted up into the upper troposphere, but a lot of smoke stays near the surface and causes air quality problems," said Robert Field, an associate research scientist at NASA’s Goddard Institute for Space Studies and Columbia University.

"It’s a horrible situation." According to the Global Fire Emissions Database (GFED), a fire emissions monitoring system, fires in Papua New Guinea, on the eastern half of the island, had released nearly 32 megatons of carbon by October 19, more than any other year on record at that point in the year. "Emissions are already much higher than the 2015 total for the year, and it’s very likely that this will become the highest year on record for Papua New Guinea, even surpassing 1997," said Guido van der Werf, a fire scientist at Wageningen University & Research. On the Indonesian side, sometimes called West New Guinea or Indonesian Papua, carbon emissions exceeded 35 megatons, the third highest after 2015 and 1997, other El Niño years with severe fires.
