This short video, adapted from NOVA, explains how Earth's position relative to the Sun might be responsible for the dramatic shift in the climate of what is now the Saharan nation of Djibouti.

This video illustrates how one community developed and implemented a sustainable solution to rising temperature in a stream.

In this activity, students utilize a set of photographs and a 3-minute video on weather to investigate extreme weather events. They are posed with a series of questions that ask them to identify conditions predictive of these events, and record them on a worksheet. Climate and weather concepts defined.

Students use real satellite data to determine 1) where the greatest concentrations of aerosols are located during the course of a year in the tropical Atlantic region and 2) their source of origin. This is an inquiry-style lesson where students pull real aerosol data and attempt to identify trends among data sets.

This narrated animation displays three separate graphs of carbon emissions by humans, atmospheric concentrations of CO2, and average global temperature as it has changed over the last 1000 years. The final slide overlays the three graphs to show how they all correspond.

This qualitative graphic illustrates the various factors that affect the amount of solar radiation hitting or being absorbed by Earth's surface such as aerosols, clouds, and albedo.

This animation depicts the carbon cycle in a fashion that is suited for younger audiences. The video discusses how carbon enters and exits the environment through both natural and human-driven ways.

This hands-on activity explores the driving forces behind global thermohaline circulation.

This flow chart shows the sources and activities across the U.S. economy that produce greenhouse gas emissions.

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