This video examines how scientists learn about the effects of climate change on the water cycle and what those effects might mean for our planet.

A short video on the causes of ocean acidification and its effects on marine ecosystems.

In this video segment, adapted from Navajo Technical College, two Navajo Elders speak about climate change and differences in the environment that they have observed.

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 well-designed experiment compares CO2 impacts on salt water and fresh water. In a short demonstration, students examine how distilled water (i.e., pure water without any dissolved ions or compounds) and seawater are affected differently by increasing carbon dioxide in the air.

A collection of repeat photography of glaciers from the National Snow and Ice Data Center (NSIDC). The photos are taken years apart at or near the same location, illustrating how dramatically glacier positions can change even over a relatively short period in geological time: 60 to 100 years. Background essay and discussion questions are included.

This animation describes how citizen observations can document the impact of climate change on plants and animals. It introduces the topic of phenology and data collection, the impact of climate change on phenology, and how individuals can become citizen scientists.

This video is the second of three short videos showcasing the dramatic changes in Alaska's marine ecosystems. The video highlights the marine mammals and birds and how they depend on Arctic sea ice, as well as questions about how these animals will cope in the face of climate change.

This animation provides a clear set of graphics related to the consequences of climate change on the Arctic (e.g., sea ice, shipping routes, permafrost, tree line).

This video adapted from Bullfrog Films examines the effects of global warming on the Pacific island of Samoa with testimonials from an expert in both western science knowledge and traditional ecological knowledge. Background essay and discussion questions are included.
