Ah, I was confused at first as well. With a name like Greening Earth Society, you have to be suspicious! However, digging a bit deeper, the GES was created by Western Fuels Association to promote the benign effects of CO2. Their site has links for studies that have been done showing that plant growth increases with increased CO2. So, in effect, the GES is on our side. Of course, with an affiliation like Western Fuels, they certainly have their own agenda to promote! :eek:
