The ESRI storymap on climate refugees does a phenomenal job sampling locations in the world that experience migration effects as a result of climate change. Though many times, there are other causes of migration shifts, it is an important cog in the gear. Attached is a guided worksheet that accompanies the ESRI Climate Migrant Storymap. Students can complete for homework or be used as guided discussion questions.
Here is the site for the Esri Storymap which they also allow to copy and paste code into a personal website as seen below.
