Carbon dioxide is the chief greenhouse gas and most of it lasts about 100 years in the air, but some of it stays in the atmosphere for thousands of years.

BZZZZZZZT! WRONG! Water is. Thanks for playing.

Some carbon dioxide is natural, mainly from decomposing dead plants and animals. Before the Industrial Age, levels were around 275 parts per million.

I wonder what the levels were before fermentation? By the way, just how much CO2 does the fermentation process to manufacture Ethanol produce??

Could 'renewable fuels' be a culprit?

Are these guys having a cold one while they are measuring?

All of the CO2 capture by growing corn should be released during processing and burning the fuel. It should be essentially CO2 neutral.
