2026 cumulative daily total fire emissions for Indonesia to 30 Sept continue to keep pace with previous El Niño years of 2015, 2019 & 2006. #CopernicusAtmosphere GFASv1.2 data available via Fire Emissions Watch apps.atmosphere.copernicus.eu/fire-emissio... @copernicusecmwf.bsky.social @ecmwf.int
Cumulative daily time series of fire emissions from Indonesia for 2003 to 2026. As of mid-September the 2026 emissions are keeping pace with the increased fire emissions during previous strong El Niño years (i.e., 2015, 2019 and 2026)Time series of daily total estimated fire emissions from Indonesia between 1 July and 31 December for all years between 2003 and 2026. Daily total emissions for 2026 have been consistent with those of the previous strong El Niño years of 2015, 2019 and 2006.

Once smoke is generated, chemical reactions reshape its gaseous and particulate constituents, altering what travels downwind and what people, ecosystems, and the climate are exposed to.

NEW for @carbonbrief.org As El Niño intensifies, the forest fires ripping through Indonesia are on track to reach levels not seen since 2015. The country's 2015 fire season has been linked to 100,000 premature deaths and produced emissions on a par with the EU's fossil-fuel emissions that year.
Line chart showing cumulative daily fire emissions in Indonesia. The 2026 trajectory, highlighted in red, rises sharply to around 75MtC and is closely tracking the early path of 2015, shown in dark blue. In 2015, emissions later surged to about 330MtC, far above the 2000–26 average of roughly 85MtC. Other years are shown in light grey. Source: Global Fire Emissions Database.
