text: **Conclusion.**According to the simulation results, the yield of maize under global warming by 2.0 °C would 
  decrease between 3.0 and 18.7% in the worldwide relative to 1986–2005; the maize yield would fluctuate between 
  − 6.8 and 7.2% under global warming by 1.5 °C. From the spatial distribution, the gross maize yield in the top 5 
  high-yield countries (including the United States, China, Brazil, Argentina and Mexico) would decrease by 2% 
  under global warming by 1.5 °C and 11.4% under global warming by 2.0 °C. At the global level, the market price 
  for maize would increase by 0.7% and 3.4% under 1.5 °C scenario and 2.0 °C scenario, respectively, which would 
  vary quite largely among different countries and regions. So, it is urgent for all countries to pay enough attention 
  to the loss risk of maize yield and take actions of mitigation and adaptation to climate change. The time left for 
  changing our minds and actions is becoming less and less.
