Large changes in biomass burning over the last millennium inferred from paleoatmospheric ethane in polar ice cores [Earth, Atmospheric, and Planetary Sciences]

Biomass burning drives changes in greenhouse gases, climate-forcing aerosols, and global atmospheric chemistry. There is controversy about the magnitude and timing of changes in biomass burning emissions on millennial time scales from preindustrial to present and about the relative importance of climate change and human activities as the underlying cause....
