A collection of repeat photography of glaciers from the National Snow and Ice Data Center (NSIDC). The photos are taken years apart at or near the same location, and at the same time of year. These images illustrate how dramatically glacier positions can change even over a relatively short period in geological time: 60 to 100 years. Background essay and discussion questions are included.

This video introduces the concept of daylighting - the use of windows or skylights for natural lighting and temperature regulation - and how it is a building strategy that can save operating costs for homeowners and businesses.

This is a series of graphical animations that compare the contribution of natural factors (including orbital changes, variability in the sun's temperature, volcanic action, deforestation, ozone pollution levels, and aerosols) to the contribution of increasing atmospheric carbon dioxide, to increases in global atmospheric temperature... in a visual and concise way.

This animated slideshow introduces biodiesel as a fuel alternative. With concern about the use of petroleum-based fuels at an all-time high, biodiesel is experiencing a popularity surge. And algaeâotherwise known to some as pond scumâ are grabbing headlines as the next potential biodiesel superstar. But how and why do algae make oil? And why do they make so much of it? In this audio slide show, U.C. Berkeley's Kris Niyogi describes the process and its potential.

This series of visualizations show the annual Arctic sea ice minimum from 1979 to 2015. The decrease in Arctic sea ice over time is shown in an animation and a graph plotted simultaneously, but can be parsed so that the change in sea ice area can be shown without the graph.

This video reviews key points as well as pros and cons of nuclear power.

This interactive visualization is a suite of weather and climate datasets as well as tools with which to manipulate and display them visually.

In this video scientists discuss possible rates of sea level rise, storms and resulting damage, rising temperatures and melting ice, and their collective effects on ecosystems.

This visualization focuses on public acceptance of climate science. The set of interactive maps illustrates public opinion on a variety of climate beliefs, risk perceptions, and policy support. The data is from the Yale Project on Climate Communication and is updated every one to two years. The most recent data at the time of this record is 2019.

This video describes the joint NASA-JAXA GPM (Global Precipitation Measurement) satellite mission and why it is necessary for monitoring precipitation around the Earth. It also discusses the science around issues of having too much or too little precipitation such as landslides and drought. It emphasizes the need for data to fill in gaps, and why data and being able to predict natural disasters is so valuable.
