An interview with a University of Illinois researcher examines how elevated CO2 and rising temperatures affect photosynthesis and productivity of Midwest corn and soybeans. The piece notes that 2019 flooding prevented planting on nearly 20 million acres.
This is long-term climate research with no immediate supply or price signal for feed markets.
After 2,467 past weather events, Corn moved a median +0.1% over 5 sessions (51% higher; middle half -1.5% to +1.7%), and +0.6% over 20.
After 1,964 past weather events, Soybeans moved a median +0.1% over 5 sessions (51% higher; middle half -1.7% to +1.8%), and +0.3% 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.
