This video provides a simple introduction to wind turbines and how they generate electricity.

This animation demonstrates the changing declination of the sun with a time-lapse animation. It shows how the shadow of a building changes over the course of a year as the declination of the sun changes.

This interactive visualization provides information in text, graphic, and video format about renewable energy technologies. Resource in the Student's Guide to Global Climate Change, part of EPA Climate Change Division.

A short video that discusses how changing climate is affecting the population of AdÃlie penguins.

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

This video is part of the Climate Science in a Nutshell video series. This short video looks at the effects of climate change happening right now around the globe, including: more extreme weather events, droughts, forest fires, land use changes, altered ranges of disease-carrying insects, and the loss of some agricultural products. It concludes with a discussion of the differences between weather, climate variability, and climate change.

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 is the first of a three-video series from the Sea Change project. It features the field work of scientists from the US and Australia looking for evidence of sea level rise during the Pliocene era when Earth was (on average) about 2 to 3 degrees Celsius hotter than it is today.

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

This interactive shows the extent of the killing of lodgepole pine trees in western Canada. The spread of pine beetle throughout British Columbia has devastated the lodgepole pine forests there. This animation shows the spread of the beetle and the increasing numbers of trees affected from 1999-2008 and predicts the spread up until 2015.
