Students explore positive feedback effects of changing albedo from melting Arctic sea ice.

Students watch a video explaining albedo and its impact on Earth. The video shows visualizations of albedo across Earth and how it can change. Students will interpret the images in the video and answer questions about albedo.

Students will analyze a graph showing the variation of energy imbalance on Earth over the year along different latitudinal zones and answer the questions that follow.

Students will watch and examine a NASA animation of Earth’s rising surface temperatures over an almost 150 year period.
