A new study from Stanford University has found that converting large swaths of farmland for large-scale cultivation of bioenergy crops could help with global warming by actually lowering surface temperatures at a regional scale.
The study, published online in the Feb. 28 edition of the Proceedings of the National Academy of Sciences (PNAS), follows a U.S. Department of Agriculture forecast that by 2018, more than one-third of the country's corn harvest will be used to produce ethanol, the announcement stated.
