Video presents a broad overview of what (NASA) satellites can tell us about how climate change is affecting oceans.

This video segment features subsistence fishing and harvesting in the Northwestern US. The segment was adapted from a student video produced at Northwest Indian College in Bellingham, Washington.

In this video segment, a team of scientists seeks evidence to support their hypothesis that atmospheric warming may cause water to form beneath the West Antarctic ice sheet. This water causes ice streams to flow much more quickly than the rest of the ice sheet, which has important implications for sea level rise.

This introductory video addresses key points as well as pros and cons of oil as an energy source for transportation.

This is a photo essay linked to a New York Times story about climate-related stressors on forests -- including mountain pine beetles, forest fires, forest clearance, and ice storms -- and the importance of protecting forests as an important carbon sink.

This video documents the challenges that climate change presents for four specific Arctic predators: polar bears, Arctic foxes, beluga whales, and walruses.

This is an interactive map of California and the Sierra Nevada mountains, showing how the amount of water stored in the snowpack will vary under different climate scenarios. The tool shows observations and projections from 1950 to 2090, and uses low or high emission scenarios to model future snowpack. The tool can be adjusted to show different months of the year and various climate models, graphed by site.

This online calculator converts from one energy unit to another - from gallons to British thermal units (Btu), kilowatt/hours to megajoules, short tons to metric tons.

This short, animated video describes what is meant by climate, its characteristics, and the range of impacts due to climate change. The difference between mitigation and adaptation is also discussed.

This video introduces phytoplankton - the base of the marine food web, the source of half of the oxygen on Earth, and an important remover of CO2 from the atmosphere. The video also explains how satellites are used to monitor phytoplankton and how warming waters and acidification negatively affect phytoplankton.
