This collection of photos from the NASA Climate website features images related to global change. Not all images show change caused directly by climate change and energy use, and descriptive captions indicate causes for change in most of the images.
This short video, the sixth in the National Academies Climate Change, Lines of Evidence series, explores the hypothesis that changes in solar energy output may be responsible for observed global surface temperature rise. Several lines of evidence, such as direct satellite observations, are reviewed.
Bell Telephone Science Hour produced this video in 1958, explaining how the production of CO2 from factories and automobiles is causing the atmosphere to warm, melting the polar ice caps, and causing the sea level to rise.
This short video describes how the compression of Antarctic snow into ice captures air from past atmospheres. It shows how ice cores are drilled from the Antarctic ice and prepared for shipment and subsequent analysis.
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 narrated animation displays three separate graphs of carbon emissions by humans, atmospheric concentrations of CO2, and average global temperature as it has changed over the last 1000 years. The final slide overlays the three graphs to show how they all correspond.
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 their 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.
