I'm not understanding the point you're trying to make. The article you posted states clearly that fossil fuels are the largest net contributor (4-5 gigatons/year) to atmospheric carbon: "Before the industrial revolution, the main source of fluctuation in atmospheric carbon was from changes in biomass and soil organic carbon. Now, fossil fuel burning is the greatest factor in atmospheric carbon fluctuations." Lots of carbon is absorbed into the soil and lots is released as part of the normal carbon cycle, with the net effect being: "The soil organic matter pool is currently losing about 1 to 2 gigatons of carbon per year to the atmospheric pool." > Erosion is not the result of global warming If global warming causes more droughts, and droughts cause soil loss, then isn't global warming contributing to erosion?
