The cattlemen's global warming files (1986–1996)
The National Cattlemen's Association's records, 719 boxes, now sit at the American Heritage Center at the University of Wyoming. Researchers Jennifer Jacquet and Loredana Loy read 154 internal documents and 48 news stories from the period. They found the association commissioned reports questioning methane science that carried no methods section and do not appear to have been peer reviewed.
One commissioned analysis appears to have counted only beef cattle, leaving out dairy cows, which pushed its estimate of livestock's contribution downward.
The association's 47-page strategic plan for 1992 and 1993 listed no specific actions on global warming, even though its own commissioned reports mentioned feed as a way to cut emissions.
The dispute over how much methane cattle produce, and whether to say so plainly, is the same one that removed the 2026 lesson.
