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 video describes how concentrating solar power (CSP) technologies reflect and collect solar energy to generate electricity. This video explains what CSP is, how it works, and focuses on parabolic troughs.
This short video uses animated imagery from satellite remote sensing systems to illustrate that Earth is a complex, evolving body characterized by ceaseless change. Adapted from NASA, this visualization helps explain why understanding Earth as an integrated system of components and processes is essential to science education.
This visualization is a chart that displays future climate change in terms of temperature increases and the impacts and Food, Water, Ecosystems, Extreme Weather Events, and Risk of Abrupt and Irreversible Changes that are predicted with the increasing temperature benchmarks.
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 provides guidance as to issues related to changing global ice cover and its measurement.
From the National Academies of Science, this video demonstrates how different strategies for coping with climate change affect different people and organizations, and emphasizes America's need for a clear, coordinated national response to the challenge.
Key figure from the 2007 Intergovernmental Panel on Climate Change (IPCC) report that shows changes in global average surface temperature, global average sea level, and Northern Hemisphere snow cover from as far back as 1850.
Teaching Climate: This CLEAN-reviewed video is part two of a seven-part National Academies series, "Climate Change: Lines of Evidence." The video outlines, with the use of recent research and historical data, how we know that the Earth is warming.
