Credit: Xu et al., 2026 A new international study published in Nature Geoscience reveals that dark brown carbon from wildfires exerts a powerful warming effect on the global climate—potentially matching or even exceeding that of black carbon in the visible spectrum. Conventional understanding has held that brown carbon—a type of organic aerosol from biomass burning—mainly absorbs sunlight in the near-ultraviolet range, giving it only a limited climate impact.
