A collection of repeat photography of glaciers from the National Snow and Ice Data Center (NSIDC). The photos are taken years apart at or near the same location, illustrating how dramatically glacier positions can change even over a relatively short period in geological time: 60 to 100 years. Background essay and discussion questions are included.

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

This animation describes how citizen observations can document the impact of climate change on plants and animals. It introduces the topic of phenology and data collection, the impact of climate change on phenology, and how individuals can become citizen scientists.

In this activity, student teams research and develop a proposal to decrease the carbon footprint of their city's/town's public transportation system and then prepare a report that explains why their transportation plan is the best for their community.

This video describes the work of scientists who are studying the precise combination of trees that would be most effective in reducing the level of greenhouse gases in the air around Syracuse, NY. This is a pilot study that will serve as a model for other urban areas.

In this instructional lesson plan, students analyze data from a study on the effects of climate warming on a subalpine meadow in Gothic CO, called the "warming meadow". This long-term experiment provides a means of discovering the actual mechanisms governing ecosystem responses to climate warming.

This qualitative graphic illustrates the various factors that affect the amount of solar radiation hitting or being absorbed by Earth's surface such as aerosols, clouds, and albedo.

This introductory video addresses key points as well as pros and cons of oil as an energy source for transportation.

This interactive map allows students to experiment with decadal average temperature projections. Overall temperatures are expected to rise throughout the century and this tool demonstrates those projected measurements.

In this activity, students examine the energy required to make a cheeseburger, calculate its associated carbon footprint, and discuss the carbon emissions related to burger production. The activity is geared toward Canadian students but can be customized to the consumption patterns and carbon footprint of American students since the resource references the amount of burgers consumed by Americans in addition to Canadians.
