Aerosols and smoke injected into the stratosphere by major events like the 2019-2020 Australian bushfires alter Earth's radiation budget, with reflective aerosol components contributing to planetary cooling and shading effects.
The retrieved literature documents that the 2019-2020 Australian bushfires produced massive amounts of stratospheric aerosols and smoke that impacted regional and global radiative balances. While absorbing aerosols like black carbon or brown carbon cause localized stratospheric warming, the broader suite of wildfire-generated aerosols contributes to solar radiation reflection and cooling effects matching the general principles of aerosol-driven climate impacts.
