How Big Agriculture Mislead the Public About the Benefits of Biofuels

Summary

Something felt off.Article continues after advertisement Tim Searchinger lacked the proper credentials to say exactly what was off that day in the spring of 2003. He was a lawyer, not a scientist or economist. He was reading a complex technical paper on an unfamiliar topic, produced by well-respected researchers at the world-renowned Argonne National Laboratory. Sitting at his cluttered desk in the Environmental Defense Fund’s sixth-floor offices in Washington, D.C., overlooking the famous back entrance to the Hilton where President Ronald Reagan was shot, he just had a sense the paper didn’t add up. Searchinger tended to distrust new information until he could study it to a pulp. He never assumed consensus views were correct, conventional wisdom was wise, or sophisticated-looking scientific analyses reflected reality. He questioned everything, so his unease that day didn’t feel particularly unusual. He had no inkling it would eventually lead him to a new profession—and the world to a new way of thinking about food, farming, land use, and climate change. The Argonne study analyzed whether fueling cars with corn ethanol rather than gasoline reduced greenhouse gas emissions, which did not seem like a particularly urgent question in 2003. And Searchinger was a wetlands guy fighting to save the streams and swamps that provide kitchens and nurseries for fish and wildlife, not an energy-and-climate guy trying to keep carbon out of the atmosphere. So it was a bit odd that he would slog through such an obscure report. He had a hunch the Argonne researchers and their spiffy analytical tools were also understating the climate costs of using grain to fuel our cars instead of ourselves.Article continues after advertisement But not too odd. He was also an agriculture guy, because farms were the main threat to the wetlands he wanted to protect. And he was above all a details guy, a data sponge willing to soak up minutiae far too technical for less obsessive laymen. The revelatory...
