In this learning activity, students use a web-based geologic timeline to examine temperature, CO2 concentration, and ice cover data to investigate how climate has changed during the last 715 million years.

In this activity students use a series of Landsat images from 1975 to 2005 to examine changes in land cover and abundance of vegetation in the summer (peak abundance) and relate these changes to climate conditions.

In this activity, students use Google Earth and team up with fictional students in Chersky, Russia to investigate possible causes of thawing permafrost in Siberia and other Arctic regions. Students explore the nature of permafrost and what the effects of thawing permafrost mean both locally and globally. Next, students use a spreadsheet to explore soil temperature data from permafrost boreholes and surface air temperature datasets from in and around the Chersky region for a 50-year time span.

In this interactive simulation, students adjust mountain snowfall and temperature to see the glacier grow and shrink, and use scientific tools to measure thickness, velocity, and glacial budget.
