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.

This detailed animated map shows global weather and climate events from the beginning of 2009 to the present. As the animation plays, specific events are highlighted to provide context and details for the viewer.

A simplified representation of the terrestrial carbon cycle side by side with the ocean carbon cycle. Fluxes and reservoirs expressed in gigatons are included.

This video explores what scientists know about how changes in global climate and increasing temperatures affect different extreme weather events.

In this activity, students investigate how sea levels might rise when ice sheets and ice caps melt by constructing a pair of models and seeing the effects of ice melt in two different situations. Students should use their markers to predict the increase of water in each box before the ice melts.
