Was ethanol industry’s rebuke of “Frontline” warranted?

The ethanol industry’s overreaction to “Heat,” a Frontline doc about climate change that aired this week, says “a great deal about the nervous state” of the industry, writes a Chicago Tribune columnist. The Renewable Fuels Association, a pro-ethanol group, attacked the doc as one-sided (PDF). But “nothing in the broadcast was new to anyone who has paid attention to the ethanol debate over the last couple years,” writes David Griesing.
