Global carbon emissions from biomass burning in the 20th century /Mouillot, F. Narasimha, A. Balkanski, Y. Lamarque, J. F. Field, C. B. We used a new, 100-year, 1 x 1 degrees global fire map and a carbon cycle model (CASA) to provide a yearly gridded estimate of the temporal trend in carbon emissions due to wildfires through the 20th century. 2700 - 3325 Tg C y(-1) burn at the end of the 20th century, compared to 1500 2700 Tg C y(-1) at the beginning, with increasing uncertainty moving backward in time. There have been major changes in the regional distribution of emissions from fires, as a consequence of i) increased burning in tropical savannas and ii) a switch of emissions from temperate and boreal forests towards the tropics. The frequently- used assumption that pre-industrial emissions were 10% of present biomass burning is clearly inadequate, in terms of both the total amount and the spatial distribution of combustion. 2006 text https://www.documentation.ird.fr/hor/fdi:010065884 fdi:010065884 Mouillot F., Narasimha A., Balkanski Y., Lamarque J.
