This video takes viewers high into the Rocky Mountain snowpack, where researchers dig snow pits to explore the source of Colorado's water supply. Highlights how important snowpack is to the supply of fresh water available in western and southwestern states. Snowmelt dynamics are discussed, including the impact of a warming climate on these dynamics.

This video from the U.S. National Academies summarizes the energy challenges the United States faces, the technological challenges, and the need for behavior and policy changes required to meet the challenge.

This short video clip summarizes NOAA's annual State of the Climate Report for 2009. It presents a comprehensive summary of Earth's climate in 2009 and establishes the last decade as the warmest on record. Reduced extent of Arctic sea ice, glacier volume, and snow cover reflect the effects of rising global temperature.

This video addresses two ways in which black carbon contributes to global warming - when in the atmosphere, it absorbs sunlight and generates heat, warming the air; when deposited on snow and ice, it changes the albedo of the surface. The video is effective in communicating about a problem frequently underrepresented in discussions of climate change and also public health.

This video introduces photovoltaic energy resources and the related science and engineering research conducted at the National Renewable Energy Laboratory (NREL).

This video reviews the benefits and drawbacks associated with growing corn to make ethanol.

Students use Google Earth to analyze oil consumption per capita in the US and around the world. Students then use spreadsheets to create graphs and calculate statistics regarding per capita energy use among various categories.

In this short video, host Dr. Ryan interviews graduate student Amy Steiker at the Institute of Arctic and Alpine Research about her research, using isotopes of nitrous oxide, connecting human activity to greenhouse gas emissions.

In this video, a PhD Student from the University of Maine explains how ice cores are used to study global climate change.

These flow charts show carbon dioxide emissions for each state, the District of Columbia and the entire United States. Emissions are distinguished by energy source and end use.
