This collection of photos from the NASA Climate website features images related to global change. 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.

In this activity, students study the relationship between changing climate conditions and the distribution of plants across North America, using a unique tool called the Pollen Viewer. This tool allows the user to animate the retreat of the North American glacier and the migration of plant species during the waning period of the most recent Ice Age.

In this video segment, adapted from a student video produced at Northwest Indian College in Bellingham Washington, Native American elders discuss the impact of climate change on salmon populations and the importance of restoring balance in the natural world.

This NOAA visualization video on YouTube shows the seasonal variations in sea surface temperatures and ice cover for the 22 years prior to 2007 based on data collected by NOAA polar-orbiting satellites (POES). El NiÃo and La NiÃa are easily identified, as are the trends in decreasing polar sea ice.

This visualization is a website with an interactive calculator that allows for estimation of greenhouse gas production from croplands in the United States.

This activity is a learning game in which student teams are each assigned a different energy source. Working cooperatively, students use their reading, brainstorming, and organizational skills to hide the identity of their team's energy source while trying to guess which energy sources the other teams represent.

This animated map shows prevailing surface wind direction and strength across the United States.

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.

In this jigsaw activity, students explore meteorological data collected from Eureka, Canada to try to decide when would be the best time for an Arctic visit.

The Electricity data browser allows individuals and organizations to create, download, or view graphs, reports and tables based on energy data sets for 2001-2013 from the US Energy Information Administration. Data sets include generation and consumption, sales, costs and quality. Can choose various ways to represent these data sets. Note: This site is being updated based on feedback from users.
