The article explores how climate change will affect global agriculture and the potential for reducing greenhouse gas emissions from the sector. Using a computer model, the researchers looked at different climate scenarios and their impact on agricultural productivity and greenhouse gas mitigation costs. They found that climate change will have significant effects on agricultural production worldwide, which will in turn affect the ability of the sector to reduce greenhouse gas emissions. This study provides valuable insights into how different regions may contribute to global greenhouse gas mitigation efforts in the face of climate change.
