Thanks for the link.

As expected, the press distorted the study's conclusions to the point of actually lying:

  "we find that the production of corn-based ethanol in the United States has failed to meet the policy’s own greenhouse gas emissions targets and negatively affected water quality, the area of land used for conservation, and other ecosystem processes"

It's one thing to "fail to meet" some emissions reductions and quite another to actually increase the emissions altogether.
