2010-08-22 ::: CO2 emission from fossil fuel burning is not more than from breathing

This essay was first posted on the Activist Teacher blog.

The present (2010) rate of CO2 emission from fossil fuel burning, expressed as kilograms of carbon per year, is 0.8 x 10^13 kg-C/y (where, in scientific notation, 10^13 = 10,000,000,000,000 with thirteen zeros). This includes all fossil fuel CO2 emissions; from petroleum, coal, natural gas, and cement production.

My calculation (below) shows that this rate of CO2 emission is roughly equal to the CO2 emissions from the simple breathing of air of humans and domestic animals (humans, cattle, swine, sheep, goats, chickens, pets, etc.), so-called anthropogenic (from humankind) animal breathing. ...
