Lol, he said "global warming!" Most brewers know that CO2 is a heavy gas and high concentrations of it sink to the lowest point. Hence the danger in venting excess CO2. Anyone who thinks that CO2 is a "greenhouse" gas is plain uninformed. Most on the west coast are familiar with the term "tree line." It's the term used to describe the highest elevation trees will grow due to the fact that there is not enough CO2 up there to sustain their growth.
So, I guess we can put this "global warming caused by CO2" crap to rest.
