This article points out through climate simulations from the National Center for Atmospheric Research (NCAR) that global warming will be increased by the end of the 21st century 3.3°C and in some areas as 7-8°C. This change will have an impact on agricultural production and human mortality. A new emphasis on the integration of social sciences with physical sciences will be fundamental to address the problem of climate adaptation; likewise, it will be important for decision-making to overcome the vulnerability and the challenges that brings a climate change
