What I understand of the studies involving organic verses other farming
practices is that organic farming has less CO2 release into the atmosphere.
Other gasses involved in the greenhouse effect are responsible for the
negative rating involving organic farming.
The effects of CO2 on global warming is greatly increased by other gases.
Any study that only looks at CO2 fails to be of much use as to prediction of
global temperature.
I wish I had keep the article but I did not, I just thought that it was
interesting.
