This short video from NASA discusses the role that salinity plays in Earth's climate and ocean circulation, focusing on the observations of the Aquarius satellite.

This visualization graphically displays temperature and CO2 concentration in the atmosphere as derived from ice core data from 400,000 years ago to 1950. The data originates from UNEP GRID Arendal's graphic library of CO2 levels from Vostok ice core.

This short, time-lapse video shows the changes in the Columbia Glacier from May 12, 2007 to August 20, 2010. Narration provides general description of the geophysical dynamics and processes.

This audio slideshow examines the changes in the ecosystem that will occur to the Arctic due to increasing temperatures and disappearing sea ice.

In this video from the Polaris Project Website, American and Siberian university students describe their research on permafrost.

This video shows where and how ice cores are extracted from the West Antarctic Ice Sheet. The cores are cut, packaged, flown to the ice core storage facility in Denver, further sliced into samples, and shipped to labs all over the world where scientists use them to study indicators of climate change from the past.

In this activity, students use authentic Arctic climate data to unravel some causes and effects related to the seasonal melting of the snowpack and to further understand albedo.

This sequence of activities using real-world data to explain the importance of coral reefs and the relationship of coral reef health to the surrounding environment. Unit includes five activities.

This easy-to-understand video animation describes drought and explains the different categories of drought used by the drought monitor. It discusses the effects of and contributions to drought, what the implications of the different drought levels are, and puts the drought maps into context to understand how the impacts vary geographically (e.g. drought in Nevada vs Kansas - one could affect tourism, the other agriculture). It also touches on how the development of maps/drought severity is determined and how it might vary geographically. The animation provides a basic overview of statistics and percentiles and the concept of '100 year events.'

This web-based activity tackles the broad reasons for undertaking ocean exploration - studying the interconnected issues of climate change, ocean health, energy and human health. Students examine the types of technology ocean scientists use to collect important data.
