This interactive visualization adapted from NASA and the U.S. Geological Survey illustrates the concept of albedo, which is the measure of how much solar radiation is reflected from Earth's surface.

Video introduces wind energy research at the National Renewable Energy Lab (NREL) and provides an overview of the NREL Wind Technology Center near Boulder, Colorado.

This is an interactive graph that involves records of ice cover in two Wisconsin lakes - Lake Mendota and Lake Monona - from 1855-2010.

This activity identifies and explains the benefits of and threats to coral reef systems. Students read tutorials, describe the role of satellites, analyze oceanographic data and identify actions that can be undertaken to reduce or eliminate threats to coral reefs. As a culminating activity, students prepare a public education program.

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.

This short NASA video focuses on the Aquarius satellite, launched on June 10, 2011 to observe how variations in ocean salinity relate to climatic changes. By measuring salinity globally, Aquarius shows the ocean's role in climate change and climate's effects on ocean circulation.

Activity in which students investigate what causes the seasons by doing a series of kinesthetic modeling activities and readings. Activity includes educator background information about how to address common misconceptions about the seasons with students.

This activity utilizes labs, online resources, and student ideas to build an understanding of polar climates, how changes in polar oceans can affect coastal climates, and how changes in polar regions affect climates elsewhere on Earth.

This video documents the challenges that climate change presents for four specific Arctic predators: polar bears, Arctic foxes, beluga whales and walruses.

This is a video that documents the reflections of members of the Steger International Polar Expedition team reunited at the 25th anniversary of their landmark trek to the Arctic, and how climate change has made their trek difficult to replicate.
