Coral Reefs in Hot Water is a short video displaying computerized data collected on the number of reefs impacted by coral bleaching around the world.

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 video provides an overview of the Center for Transportation Technologies and Systems and its research on alternative fuel vehicles and why they have less impact than current fossil fuel-burning cars on the environment.

This interactive visualization provides a clear, well-documented snapshot of current and projected values of several climate variables for local areas in California. The climate variables include observed and projected temperatures, projected snowpack, areas vulnerable to flooding due to sea level rise, and projected increase in wildfires. The projected values come from expert sources and well-established climate models.

In this hands-on activity, students explore whether rooftop gardens are a viable option for combating the urban heat island effect. Guiding question is: Can rooftop gardens reduce the temperature inside and outside houses?

In this activity, students model circulation in gyres, explore characteristics of gyres found around the world, and predict the climate impacts of changes to the circulation in these gyres and climate on adjacent land. Gyres, large systems of rotating ocean currents, play an important role in Earth's climate system.

This static graph of changes in CO2 concentrations is going back 400,000 years, showing the dramatic spike in recent years.

This is a classroom activity about the forcing mechanisms for the most recent cold period: the Little Ice Age (1350-1850). Students receive data about tree ring records, solar activity, and volcanic eruptions during this time period. By comparing and contrasting time intervals when tree growth was at a minimum, solar activity was low, and major volcanic eruptions occurred, they draw conclusions about possible natural causes of climate change and identify factors that may indicate climate change.

This video is one of a series produced by the Switch Energy project. It reviews the pros and cons of natural gas as a source of energy.

Video introduces wind energy research at the National Renewable Energy Lab (NREL) and provides an overview of the NREL Wind Technology Center near Boulder, Colorado.
