With the unending avalanche of embarrassments in climate science recently, global warming “deniers” are becoming ever more strident in their triumphalism over defeat of the “warmists.” I must admit that I have not familiarized myself with the science behind the IPCC report.  But there is a simple, irrefutable fact that those committed to rational inquiry must not lose track of, and that is that we have been pumping a hell of a lot of carbon dioxide into the atmosphere.

This can be corroborated with CO2 measurements from around the world and is really not contested.

However, some people seem to still believe that this change could not be caused by human activity.  Here I present a simple, back-of-the-envelope computation to measure the total weight of CO2 in the atmosphere, compared to the total weight of CO2 released by burning fossil fuels. more))
