CO2 Attribution RSM

This page is for the corrected version of Attribution of Surplus CO2 in the Atmosphere (December 13, 2015), which replaces the original article, published around December 10-11.

Sources & Methodology

• In accordance with IPCC views, so-called Airborne Fraction (AF) was used for calculations, and assumed constant and equal 45%.
• Annual emissions data from fossil fuels according to the Carbon Dioxide Information Analysis Center-Fossil Fuels (CDIAC-FF) from 1850 to 2011 [Boden et al., 2013]
• Annual emissions data from land use change according to the Carbon Dioxide Information Analysis Center-Land Use Change (CDIAC-LUC) from 1850 to 2005, [Houghton, 2008], extrapolated by the author through 2011

Fossil fuels emissions from China before 1902 were not included.  The 2015 correction to the recent fossil fuels emissions by China was not included. Some data was disregarded as insignificant: CO2 release by all countries prior to 1850 and land use change CO2 release by Australia.
