This video, from Yale Climate Connections, explores the 2014 melting of the West Antarctic ice sheet that captured headlines. Interviews, animations, and news broadcasts explore what the melting meant for both the future of some of the Antarctic glaciers and sea level rise, and informs the viewer how seafloor terrain influences the speed of ice sheet melt.

In this activity, students compare carbon dioxide data from Mauna Loa Observatory, Barrow, Alaska, and the South Pole over the past 40 years. Students use the data to learn about what causes short-term and long-term changes in atmospheric carbon dioxide. This activity makes extensive use of Excel.
