This video describes how the normal thousands-of-years-long balance of new ice creation and melting due to ocean currents has been disrupted recently by warmer ocean currents. As a result, glacier tongues that overhang the interface between ice and ocean are breaking off and falling into the ocean.

In this video, NOAA's Deke Arndt, Chief of the Climate Monitoring Branch at the National Climatic Data Center, recaps the temperature and precipitation data for the continental US in summer 2012. It describes how these conditions have led to drought and reduced crop yields.

This video montage of spectacular NASA satellite images set to music shows different types of ice and ice features as well as descriptions of satellite-based measurements of ice cover. Text captioning describes how global ice cover is changing, and how this is measured.

This color-coded map displays a progression of changing five-year average global surface temperatures anomalies from 1880 through 2010. The final frame represents global temperature anomalies averaged from 2006 to 2010. The temperature anomalies are computed relative to the base period 1951-1980.

This Changing Planet video documents scientists' concerns regarding how melting Arctic sea ice will increase the amount of fresh water in the Beaufort Gyre, which could spill out into the Atlantic and cause major climate shifts in North America and Western Europe. The video includes interviews with scientists and a look at the basics of how scientists measure salinity in the ocean and how ocean circulation works in the Arctic.

This National Geographic video explains the origins of the El NiÃo Southern Oscillation using animations and shows the impacts on humans, wildlife and habitat, particularly in the United States.

This video is accompanied by supporting materials including background essay and discussion questions. The focus is on changes happening to permafrost in the Arctic landscape, with Alaska Native peoples and Western scientists discussing both the causes of thawing and its impact on the ecosystem. The video shows the consequences of erosion, including mudslides and inland lakes being drained of water. An Inuit expresses his uncertainty about the ultimate effect this will have on his community and culture.

This interactive animation focuses on the carbon cycle and includes embedded videos and captioned images to provide greater clarification and detail of the cycle than would be available by a single static visual alone.

This video documents how scientists, using marine algae, can study climate change in the past to help understand potential effects of climate change in the future.

This video documents the impact of the 2011 drought on the water supply of two Texas towns. It discusses how the higher temperatures have increased the evaporation from open reservoirs, resulting in a drop in water levels. The use of water in fighting wildfires has also contributed to this drawdown. While some jurisdictions have been able to develop pipelines to other sources, others have had to resort to trucking water in.
