Study: Ethanol may add to global warming

Here is an interesting article from Yahoo.

I thought it was at least worth checking out.

"The researchers said that past studies showing the benefits of ethanol in combating climate change have not taken into account almost certain changes in land use worldwide if ethanol from corn — and in the future from other feedstocks such as switchgrass — become a prized commodity.

'Using good cropland to expand biofuels will probably exacerbate global warming,' concludes the study published in Science magazine."

I'm not sure how good their assumptions are, but you can decide for yourself.
