DTN's ag meteorologist reviews research from MIT suggesting that dense crop canopies from intensive agriculture have cooled summer temperatures and increased rainfall in the central US. Corn production has grown sevenfold since 1950 as the Corn Belt expanded.
Evidence that crop canopy affects local weather highlights a feedback loop in Corn Belt yields, but it is a background climate-science point with no direct price impact.
After 445 past neutral weather events, CORN moved a median +0.1% over 5 sessions (52% higher; middle half -1.4% to +1.6%), and +0.7% over 20.
Moves of each commodity's benchmark from the last close before the event. Historical reads pool past events of the same kind; they describe what happened, not what will. Not investment advice.
