This video and accompanying essay examine ways to reduce the environmental impact of burning coal. Two technologies are discussed: turning solid coal into a clean-burning fuel gas (syngas), and capture and storage of CO2.

In this interactive, students can investigate a typical hydrogen fuel cell prototype car from its fuel cell stacks to its ultracapacitor, a kind of supplementary power source.

The limited-production vehicle seen in this feature is a Honda 2005 FCX, which is typical of the kinds of hydrogen fuel cell cars that some major automakers are researching and developing.

As a segment in PBS's Coping with Climate Change series, Hari Sreenivasan reports on the actions the city of Chicago is taking to mitigate climate change in an urban landscape.

This slideshow lays out a photo story with short descriptions of how designers of city buildings all over the world are taking climate change and rising sea level seriously.

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.

The video offers a simple and easy-to-understand overview of climate change. It poses basic questions such as 'What is it?' and 'How will it effect us?' and effectively answers those questions.

This visualization focuses on public acceptance of climate science. The set of interactive maps illustrates public opinion on a variety of climate beliefs, risk perceptions, and policy support. The data is from the Yale Project on Climate Communication.

This video documents the impact of the 2011 drought on the water supply of two Texas towns. It discusses how the higher temperatures have increased the evaporation from open reservoirs, resulting in a drop in water levels. The use of water in fighting wildfires has also contributed to this drawdown. While some jurisdictions have been able to develop pipelines to other sources, others have had to resort to trucking water in.

A short video on the causes of ocean acidification and its effects on marine ecosystems.

This is a simulation that illustrates how temperature will be affected by global CO2 emission trajectories. It addresses the issue that even if global emissions begin to decrease, the atmospheric concentration of CO2 will continue to increase, resulting in increased global temperatures.
