New research suggests that no-till farming could help mitigate climate change.
A study from Iowa State University, released Monday, examined Midwest land use between 1850 to 2015. As agriculture and the practice of tilling spread, less carbon was being stored in the ground and more was going into the atmosphere. That added to the carbon emissions already accumulating from burning coal and driving cars.
A solution, according to study co-author Chaoqun Lu, is ending tilling.
