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 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 montage of spectacular NASA satellite images set to music shows different types of ice and ice features as well as descriptions of satellite-based measurements of ice cover. Text captioning provides guidance as to issues related to changing global ice cover and its measurement.
This video features Austria's Sonnblick Mountain Weather Station, which is the oldest high-elevation weather station in the world, and its structure is being threatened by permafrost melting beneath. It is important to preserve the weather station's integrity because it has been collecting weather data for over 100 years and provides important information about how climate is changing in the Alps.
This NASA video presents animations, photos and footage of melting polar ice as a result of climate change, the resulting sea-level rise, and selected consequences of that rise. Excellent animations, interviews with scientists, and clear step-by-step explanations provide a solid introduction to one facet of sea level rise and its consequences.
This interactive map from National Geographic shows selected geographic locations for a number of impacts of global warming (on freshwater resources, food and forests, ecosystems, etc). Impact overview is summarized for each highlighted impact.
This video, along with a background essay, focuses on impacts of climate change on the lives of Native Alaskans around Barrow, Alaska. Specific changes include the timing of the changes in the formation and breakout of sea ice and the impacts on subsistence living.
This interactive world map shows the impact of a global temperature rise of 4 degrees Celsius on a variety of factors including agriculture, marine life, fires, weather patterns, and health. Hot Spots can be clicked on to get more specific information about the problems in different regions.
This short video examines the recent melting ice shelves in the Antarctica Peninsula; the potential collapse of West Antarctic ice shelf; and how global sea levels, coastal cities, and beaches would be affected.
