Crop switch likely to increase emissions Good science news (or bad, depending on your point of view) has arrived with two reports on the carbon footprint of biofuels, in the paper edition of Science magazine. They deal serious damage to the belief - which up to now has been driving the biofuel bubble - that stepped-up ethanol production in the US is an answer to global warming.â¦
