This is a National Geographic short video that briefly describes how succulent plants in the South African Karoo biome are dying off due to changes in climate.

This figure shows the various astronomic cycles that influence long-term global climate cycles (Milankovitch cycles), plotted on the same time scale for easy comparison.

In this lab activity, students use brine shrimp as a proxy for krill to study how environmental factors impact behavioral responses of krill in the unique environment of Antarctica.

This video introduces the concept of daylighting - the use of windows or skylights for natural lighting and temperature regulation - and how it is a building strategy that can save operating costs for homeowners and businesses.

This is a photo essay linked to a New York Times story about climate-related stressors on forests -- including mountain pine beetles, forest fires, forest clearance, and ice storms -- and the importance of protecting forests as an important carbon sink.

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, and at the same time of year. These images illustrate 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.

In this activity, students use the GLOBE Student Data Archive and visualizations to explore changes in regional and seasonal temperature patterns.

In this activity, students explore real data about renewable energy potential in their state using a mapping tool developed by NREL (National Renewable Energy Laboratory) to investigate the best locations for wind energy, solar energy, hydropower, geothermal energy, and biomass.

This video highlights a variety of climate change research initiatives from scientists at the University of Colorado, Boulder. It describes the changing dynamics of Antarctic ice sheets and the impacts of reduced Arctic sea ice. The video illustrates the excitement of this research through interviews and video clips of scientists in the field.

In this activity, students use a physical model to learn the basics of photosynthesis and respiration within the carbon cycle.
