This video discusses observations of two key warning signs of global change effects on the Southern Ocean: changes in Antarctic bottom water and ocean acidification.

This activity engages learners to make a model of sediment cores using different kinds of glass beads and sand. They learn how to examine the types, numbers, and conditions of diatom skeletons in the model sediment cores and tell something about the hypothetical paleoclimate that existed when they were deposited. The students get to be climate detectives.

This carbon calculator, developed by the EPA, guides students in calculating their carbon footprint and then using that information to make decisions about how to reduce their carbon emissions.

This activity offers an introduction to working with Geographic Information Systems (GIS) by using field data on the Urban Heat Island Effect that was collected by students. The field data is entered in the GIS, displayed in a map, and analyzed.

This video provides a good overview of ice-albedo feedback. Albedo-Climate feedback is a positive feedback that builds student understanding of climate change.

This video looks at the impact of changing climate on animal habitats around the world, showing how different creatures are responding to changing temperatures and precipitation patterns.

This visualization, from the US Geological Survey, provides a simple schematic of the various pathways that water can take as it cycles through ocean, lakes, atmosphere, surface and ground.

This video describes why tropical ice cores are important and provide different information than polar ice cores, why getting them now is important (they are disappearing), and how scientists get them. The work of glaciologist Lonnie Thompson is featured, with a focus on his work collecting cores of ice from high mountain glaciers that contain significant data about past climate change.

This video highlights a variety of current climate change research initiatives from scientists at the University of Colorado, Boulder. It describes the changing dynamics of Antarctic ice sheets and glaciers and the impacts of reduced Arctic sea ice on people, animals, and global albedo and sea levels, while providing a glimpse of the excitement of this field research through interviews and video clips of scientists in the field.

This is the first of three short videos showcasing the dramatic changes in Alaska's marine ecosystems through interviews with scientists and Alaska Natives. This introduction to the impacts of climate change in Alaska includes interviews with Alaska Natives, commentary by scientists, and footage from Alaska's Arctic.
