  **Discussion.**Our analysis highlights the effects of climate change on global- and regional-specific maize 
  yields and the associated economic consequences in 1.5 °C and 2.0 °C -warming scenarios. We find that the 
  reduction risk of maize yield under global warming by 2.0 °C is much more serious than that under global warm- 
  ing by 1.5 °C. On the one hand, the larger the temperature rise, the greater the evapotranspiration would be. 
  Although the precipitation is also increasing, the evapotranspiration would become more intense. The limitation 
  of water supply for maize growth leads to the decline of yield. On the other hand, relative to global warming by 
  1.5 °C, maize production would be faced with more serious and frequent extreme climate events, such as drought 
  and heat waves, which would increase the risk of corn yield reduction under global warming by 2.0 °C. In the
