Farmers turn to engineered corn to adapt to drought. But will it be enough?

The current U.S. drought will cause at least $18 billion in crop damage this year. And climate models suggest that drought will only get more severe in the years ahead. So how will farmers cope? Many scientists are hoping genetically engineered crops could help provide the answer, but not everyone's convinced that it will be enough.

Mitt Romney once said that "it's important for us to reduce our emissions of pollutants and greenhouse gases." Paul Ryan once accused climate scientists of trying to "intentionally mislead the public." Those sound like very different views. But when it comes to energy and climate policy, Ryan and Romney don't disagree much at all.
