In this video, adapted from KUAC-TV and the Geophysical Institute at the University of Alaska, Fairbanks, viewers learn how one-celled organisms in permafrost may be contributing to greenhouse gas levels and global warming.
This is a short NASA video on the water cycle. The video shows the importance of the water cycle to nearly every natural process on Earth and illustrates how tightly coupled the water cycle is to climate.
This video features a short animated sequence that illustrates the difference between young and old carbon released into the atmosphere from the consumption of food (young carbon) and the burning of fossil fuels (old carbon).
This narrated slide presentation shows the carbon cycle, looking at various parts of this biogeochemical sequence by examining carbon reservoirs and how carbon is exchanged among them and the atmosphere.
This audio slideshow/video describes the Greenland ice sheet and the difficulties in getting scientific measurements at the interface between the ice and the ocean. It features the work of a researcher from Woods Hole Oceanographic Institute researcher. She gives a personal account of her work on the recent increase in melting of glaciers, the challenges of working in Greenland, and the reasons why so many climate scientists are looking there for answers to questions about climate change.
This video is one of a series from the Switch Energy project. It presents pros and cons of hydraulic fracturing, or fracking. In this video, new fracking technologies are presented as more economical and environmentally safe.
In this short video, host Dr. Ryan interviews graduate student Amy Steiker at the Institute of Arctic and Alpine Research about her research, using isotopes of nitrous oxide, connecting human activity to greenhouse gas emissions.
This narrated slideshow describes the impact of sea level rise on Tuvalu, one of the low-lying island nations in the South Pacific. As the frequency and intensity of floods and cyclones increases, the island is shrinking and saltwater intrusion is affecting local food production on the plantations. As a result, many residents are moving off the island to New Zealand, where they face major cultural changes.
This interactive animation focuses on the carbon cycle and includes embedded videos and captioned images to provide greater clarification and detail of the cycle than would be available by a single static visual alone.
