This short NASA video focuses on the Aquarius satellite, which was launched in 2011 to observe how variations in ocean salinity relate to climatic changes. By measuring salinity globally, Aquarius shows the ocean's role in climate change and climate's effects on ocean circulation.

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 documentary film takes the viewer on a virtual trip around the world to visit communities in different countries (Asia, Africa, Central America, Australia) taking action on climate change.
