This video discusses two key signs of global change in the Southern Ocean: changes in Antarctic bottom water and ocean acidification.

This short video shows how humanity uses energy today; what sources we use; and why, in the future, a growing global population will require more energy.

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 collection of photos from the NASA Climate website features images of global change, such as floods, wildfires, and retreating glaciers. Not all images show change caused directly by climate change and energy use, and descriptive captions indicate causes for change in most of the images.

A set of eight photographs compiled into a series of slides explain how urban areas are facing challenges in keeping both their infrastructure and their residents cool as global temperatures rise. Chicago is tackling that problem with a green design makeover. This report is part of PBS's Coping with Climate Change series and could challenge students to consider engineering designs to help their own cities be greener.

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 introductory video summarizes the process of generating solar electricity from photovoltaic and concentrating (thermal) solar power technologies.

This short, engaging video created by NASA presents a complex topic via a simple analogy. The idea of positive and negative feedback is demonstrated by Daisyworld - a world with black and white flowers growing on it.

This video explains what is involved in conducting a home energy audit. Such an audit evaluates how much energy you use in your house and suggests the most cost-effective measures you can take to improve the energy efficiency of your home. The outcomes are the use of less energy resulting in cost-savings on your energy bills.

This short video makes the case that rapid climate change affects the whole planet, but individuals can make a difference and make their carbon footprint smaller. Common suggestions are identified for young children to consciously consider what they can do.
