New Paper: Humans Caused Central U.S. To Cool By -0.35°C Since The 1940s As Crop Yields Soared

Post-1940s ‘Agricultural Intensification’
Caused Deep Cooling, 400% Crop Growth
In a new paper published in Geophysical Research Letters, three MIT scientists assert that the human influence on the climate of the Central United States is dominated by agricultural activity rather than greenhouse gas (GHG) emissions.
Human activity has caused a significant long-term cooling trend (-0.35°C between the 1940s and 2009) and higher rainfall totals via the mechanism of “agricultural intensification†– a photosynthesis-associated increase in the air’s water vapor or humidity levels due to an explosive (400%) increase in crop production and yield since the 1940s.
