How Big Agriculture Mislead the Public About the Benefits of Biofuels: Michael Grunwald on the Cascading Impact of Ethanol Production on Climate Change (Michael Grunwald, July 21, 2025, LitHub)
Searchinger’s spidey-sense kept tingling, though. His father, another question-everything guy, liked to quote H. L. Mencken: “For every complex human problem, there’s a solution that’s clear, simple and wrong.” That’s what ethanol felt like. And the more he thought about the study, the less he understood its conclusions.
Yes, corn soaked up carbon as it grew. But it soaked up just as much carbon whether it was grown for fuel or food! Why would growing corn for ethanol and burning it in an engine be any climate-friendlier than growing that same corn for food and burning an equivalent amount of gasoline in an engine? The carbon absorbed in the field wouldn’t change; neither would the carbon emitted from the car. If the only difference was that producing ethanol emitted much more carbon than producing gasoline, where were ethanol’s benefits?
That led back to his original concern: If more corn was diverted from food to fuel, how would the lost food be replaced? Presumably, Midwest farmers would plant more corn, converting more wetlands into farmland that would get blasted with more chemicals. Again, he wasn’t focused on the climate impact, just the environmental impact of losing habitat and increasing pollution. But 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.
