To the extent that deforestation has been significant, its contribution to airborne CO2 would be higher than previously estimated and the fraction of fossil fuel emissions retained in the atmosphere consequently lower. We do know that currently, half of the earth’s carbon remains in the forests still standing. We also know that between 1850 and 1890 83 gigatons of carbon dioxide were released into the atmosphere as a consequence of deforestation. But what about the carbon released due to earlier massive deforestations chronicled in A Forest Journey ? What makes this accounting so crucial is that most of this destruction occurred in temperate lands where much of the land subsequently fell to agriculture, which further degraded the soils where more carbon is stored than in the trees themselves.
