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.

Check out the Arctic and Earth SIGNs video to explore how climate models are used in climate change research.
This activity is one of a series in the collection, The Potential Consequences of Climate Variability and Change activities.
In this activity, students use satellite images from the NASA Landsat team to quantify changes in glacier cover over time from 1986 to 2018.
In this experiment, students make a claim about the cause of ocean currents and then develop a model to explain the role of salinity and density in deep ocean currents. This lesson is modified from "Visit to an Ocean Planet" Caltech and NASA/Jet Propulsion Laboratory.
How much do you know about the frozen poles of our home planet?
Students explore positive feedback effects of changing albedo from melting Arctic sea ice.
