Global warming reports: poor prospects for corn ethanol

Global warming could scorch the corn economy to the tune of about $1.4 billion a year, according to a report that compiles data from academia and government. The damage would come in the expected places: the Midwest and South, according to the Environment America study released Thursday.

The report contradicts assurances from climate-change skeptics that warming would have a net benefit on agriculture by increasing growing seasons and crop yields.
