"Experts warn of long-term climate change impacts on food" The Hills E2Wire

"The U.N. and global leaders have paid particular attention in recent weeks to U.S. biofuels policy as drought ravages corn supplies. They say the country needs to free up more of its corn for food to combat rising prices that heavily affect poor nations.
The United States, a major international corn exporter, reserves 40 percent of its corn acreage for biofuels production. U.S. corn has hit record highs of above $8 per bushel this summer.

Environmentalists and poverty activists have pushed the Environmental Protection Agency (EPA) to waive or end a rule that requires refiners to blend 13.2 billion gallons of corn ethanol into traditional fuel this year. They contend it contributes to some of the price shocks in global food markets that the drought has exacerbated. "
