With ArcGIS and climate data from the National Center for Atmospheric Research (NCAR) Climate Change Scenarios GIS Data Portal, you will learn the basics of GIS-based climate modeling. First, you will calculate summer average temperatures during the growing season (June, July, and August) using simulated, present-day, climate-modeled output (1980 to 1999). Then, you will make the same calculations using projected, future, climate-modeled output (2021 to 2040). Next, you will visually compare the temperature differences for the two model runs. Finally, you will create a temperature anomaly map to highlight areas around the globe that will experience either air temperature increases or decreases in 2030 relative to 1990.
