The ocean's surface is not level, and sea levels change in response to changes in chemistry and temperature. Sophisticated satellite measurements are required for scientists to document current sea level rise.

Students watch a short video to gather information about sources of methane emissions and then extend their understanding of these sources to evaluate monthly trends in the Alaska region, ultimately making connections to Earth’s energy budget.

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

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